    Weathering prevention of plate glass {ANTI-WEATHERING SYSTEM FOR FLAT GLASS}
    [32] The present invention relates to preventing the weathering effect of alkali eluting on the surface of the plate glass to reduce the transparency of the plate glass. In order to explain the present invention will be described with respect to the manufacturing process of the plate glass and the constituent material of the plate glass. The main raw material for producing flat glass is silicon oxide. This silicon oxide is difficult to dissolve in a general melting furnace at a high temperature of more than 1500 ℃.
    [33] Thus, alkali materials are mixed and dissolved to lower the melting temperature of silicon oxide. Alkali-dissolved silicon oxide is plasticized because it does not have a constant solidification temperature and gradually solidifies as the temperature drops. Therefore, it can be molded into a mold. In other words, the dissolved silicon oxide molecules have high intermolecular viscosity, and when cooled and solidified, irregular silicon particles are fixed and bonded silicon oxide molecules and intermolecular gaps are formed (see Fig. 2). The glazing is cooled and reinforced with the fill gap exposed on the surface to produce a pane. Since the plate glass is repeatedly expanded and contracted according to the change of ambient temperature and humidity, alkali filled in the gap between silicon oxide molecules inside the plate glass is slowly eluted to the surface.
    [34] The eluted alkali combines with the fine particles in the air on the surface of the plate glass, reducing the transparency of the glass and blurring the glass surface. This is called weathering of the glass. The glass is molded in a molten state, and the molded glass is slowly cooled down (ANNEALING). When the glass glass temperature reaches 480 ℃ (fluorinated hydrocarbon refrigerant ignition point) at the time of refrigeration, the molecular density of the hydrocarbon fluoride gas (refrigerant R152A) is uniformly distributed between the air and the hydrocarbon fluoride gas at a constant ratio. When contacted with the flat glass surface in the opened state, the fluorocarbon (refrigerant R152A) is combusted on the flat glass surface to produce oxygen fluoride steam and carbon dioxide gas. The generated oxygen fluoride and water vapor act on the surface of the plate glass to neutralize the alkali filled in the intermolecular gap exposed on the glass surface and form a molecular structure as shown in FIG. 2 so that there is no alkali eluted to the surface of the plate glass. In order to achieve this effect, conventionally, the glass surface may be cleaned with sulfuric acid or hydrofluoric acid solution, or SO 2 gas may be injected. By the way, when cleaning with sulfuric acid and hydrofluoric acid solution, the cleaning device, etc. should be made of expensive special alloy, and the material is toxic and not easy to handle. By the way, the hydrocarbon fluorinated refrigerants R152A and R134A are stable in their composition and are odorless and non-toxic under a certain temperature. As described above, when the surface temperature of the glass glass reaches the fluorinated hydrocarbon fluoride refrigerants R152 and R134, the hydrocarbon fluoride refrigerant is reacted with combustion, and the toxic substance generated therein is combined with molecules constituting the plate glass on the glass surface. Toxic oxygen fluoride is not released into the atmosphere as the material is produced. This prevents the elution of alkali, which causes weathering. An object of the present invention is to prevent the weathering of the plate glass to prevent the glass of the automobile glass and the building made of the plate glass due to the weathering effect is blurred. At present, there is no process to semi-permanently prevent weathering and improve transparency by structurally changing molecules on the surface of the glass plate as in the present invention. In order to prevent the flat glass produced by the flat glass manufacturer from being blurred by weathering during distribution, the product is thoroughly packed and the temperature and humidity of the storage warehouse are controlled to minimize the weathering. Another method is to coat the surface of the pane with a transparent material to temporarily prevent weathering.
    [35] The technical problem of the present invention for preventing the weathering action of the plate glass semi-permanently is to first make the hydrogen fluoride hydrocarbon refrigerant (R152A) gas is uniformly burned and reacted on the surface of the plate glass to make the light transmittance and reflectivity of the plate glass uniform. . If the molecular structure of the glass surface formed by the combustion reaction is not uniform, the light transmittance and reflectivity is uneven, so that the surface of the glass plate is stained. And when the surface of the plate glass is uneven, it may cause defects when cutting the plate glass. This ensures that the molecular density of the hydrocarbon fluoride (R152A) that burns on the surface of the pane is always uniformly burned.
    [36] Oxygen fluoride produced by the combustion of fluorocarbons reacts on the surface of the plate glass, and the remaining traces of oxygen fluoride are polluted when released into the atmosphere as toxic substances, and the polluted atmosphere may cause harm to everyone including workers. . In order to minimize the oxygen fluoride discharged to the atmosphere, the mixing ratio of air and oxygen fluoride refrigerant is mixed with the density of refrigerant molecules contained in the mixed gas. Therefore, the second technical task of the present invention is to reduce the amount of expensive refrigerant consumed and to reduce the amount of toxic oxygen fluoride, which is not only economically profitable.

    [37] The configuration of the present invention for solving this technical problem is to maintain a constant supply pressure and the liquid refrigerant automatic supply device 100 that can continuously supply the refrigerant, by evaporating the refrigerant in the supplied liquid state of a constant pressure, a certain temperature Evaporation apparatus 200 made of superheated steam, mixing apparatus 300 to maintain a constant molecular density of refrigerant steam in a state where the refrigerant and air in a superheated steam mixture at a constant ratio, air and refrigerant vapor at a constant ratio Combustion apparatus 400 for injection combustion on the surface of the plate glass in a mixed state, and a purification apparatus 500 for neutralizing the toxic substances generated during combustion.
    [38] The function of each component is explained in more detail as follows.
    [39] ○ Automatic liquid refrigerant supply
    [40] The refrigerant saturation vapor pressure in the vessels 104 and 105 in which the refrigerant is stored varies with temperature. If the liquid refrigerant stored in the containers 104 and 105 is supplied to the evaporator 200 by saturated steam pressure, the supply pressure of the refrigerant flowing into the high-performance automatic expansion valve 201 for adiabatic expansion of the liquid refrigerant is changed. Therefore, the adiabatic expansion outlet pressure is changed accordingly. To prevent this, the compressed air is supplied to the valve connected to the gas part inside the container 104 and 105 filled with the refrigerant much higher than the saturated steam pressure of the refrigerant in the container, and the compressed air pressure is kept constant.
    [41] Compressed air pressure used in the plate glass manufacturing plant is about 5kgf / ㎠ or less and the saturated steam pressure of the refrigerant (R152A) in the vessel is about 7kgf / ㎠ when the ambient temperature is 35 ℃. Therefore, in order to supply the refrigerant at a constant pressure regardless of the season, the compressed air pressure supplied to the gas portion inside the container must be maintained at a constant pressure of about 8kgf / ㎠ or more. To this end, the air pressure regulating valve 101 which maintains the pressure supplied at a constant pressure at all times and the back pressure 102 which doubles the pressure of the compressed air supplied from the air pressure regulating valve are applied to the container 104 and 105 gas portions. Compressed air of constant pressure of 8kgf / ㎠ or more is supplied.
    [42] It has two containers A 104 and B 105 filled with refrigerant and detects when all liquid refrigerant in container A is discharged, so that the liquid refrigerant in container B is supplied, and even when containers A and B are replaced. There is an accumulator 110 to always supply a constant pressure liquid refrigerant to the evaporator 200. The accumulator 110 has all of the liquid refrigerant from the container A 103 flowing into the inlet 112, and when the compressed air is introduced, the compressed air introduced is lighter than the liquid so that the liquid level detector on the accumulator 110 is upper. The liquid surface inside the liquid level sensor 111 descends. Upon detection, the solenoid valve SV1 connected to the vessel A 104 is closed, the solenoid valve SV2 connected to the vessel B 105 is opened, and the refrigerant filled in the vessel B 105 flows into the accumulator 110. do. At this time, the solenoid valve SV3 is opened and the air inside the liquid level detector 111 is discharged while the air in the upper portion of the liquid level detector 111 is raised, and when the liquid level reaches a predetermined position, the solenoid valve SV3 is closed.
    [43] Capillary tube for controlling the amount of compressed air discharged through the solenoid valve SV3 so that the supply pressure of the refrigerant flowing into the accumulator outlet pipe 113 does not change even when the refrigerant supply is replaced with the container A or the container B ( CT) is connected.
    [44] ○ The liquid refrigerant of constant pressure supplied to the evaporator 200 is adiabaticly expanded at a constant pressure in the automatic expansion valve (EV), and the expanded refrigerant is heated in the heat exchange coil 203 inside the evaporator to maintain a constant pressure and a constant temperature. Furnace is introduced into the mixing device (300).
    [45] ○ Compressed air of a constant pressure is introduced into the mixing device 300 through an air pressure control valve 301 that maintains a constant pressure of the air supplied to the mixing device 300, and a constant pressure and a constant temperature from the evaporator 200. The superheated steam refrigerant of is supplied to the mixer through the flow control valve 303. In the mixer 304, the compressed air introduced and the refrigerant in the superheated vapor state have different ratios of the number of molecules of the two gases mixed according to the pressure of the two gases when the two kinds of gases are mixed with each other in the gas state.
    [46] The amount of compressed air must be maintained at a constant pressure in order to transport the refrigerant molecules to be burned to the surface of the pane and to react efficiently with the burned oxygen fluoride and water vapor at the surface of the pane.
    [47] It is supplied at a constant pressure to form a constant air flow on the surface of the plate glass to form a flowing air layer. In order to maintain a constant ratio mixing ratio in the flow of the air, the refrigerant pressure flowing into the mixer 304 evaporated from the evaporator 200 should always be higher than the air pressure. The pressure of the mixed gas inside the mixer 304 is a pressure obtained by subtracting the pressure loss due to the flow rate of the refrigerant supplied from the flow rate control valve 303 to the refrigerant pressure evaporated from the evaporator 200. Therefore, the flow rate control valve 303 is displaced to adjust the flow rate, thereby controlling the flow rate of the refrigerant flowing into the mixer 304 and thereby controlling the amount of the refrigerant reacting on the surface of the plate glass.
    [48] ○ Gas mixed with air and refrigerant is supplied to the combustor through the distribution pipe (305). The combustor 400 is evenly sprayed on the glass surface through the nozzle at the portion where the surface temperature of the plate glass reaches the temperature at which the refrigerant R152A ignites. The injected refrigerant and air reach the surface of the plate glass, and after a predetermined time passes as shown in FIG. 1, a combustion reaction occurs and sparks are generated. A temperature sensor for sensing the temperature of the flame (T 1, T 2,. . T n) depending on the temperature sensed by the automatic adjustment is controlled by variable 302 the flow rate of refrigerant flowing into the mixer 304. That is, if the amount of refrigerant flowing into the mixer increases the length of the flame, and the detected temperature value is high, if the amount of refrigerant is small, the length of the flame is shortened and the temperature value is low. At this time, when a large amount of refrigerant is injected to lengthen the flame, the glass surface is blurred. Therefore, the length of the flame must be kept constant. The flow control valve 303 is to manually control the length of the flame and the automatic control valve 302 is the temperature value detected by a plurality of temperature sensors (T 1 , T 2 , ... T n ) in continuous operation The amount of refrigerant flowing into the combustor is automatically controlled based on the calculated value.
    [49] The refrigerant R152A used at this time is burned with C 2 H 4 F 2 to generate oxygen fluoride, water vapor, and carbon carbonate, and double oxygen fluoride and water vapor react with the glass surface. Reaction gases generated and reacted on the surface of the pane are sucked into the purifier.
    [50] The purifier 500 is composed of a combustor 501 and a septic tank 502, and the combustor is a porous ceramic heater, the gas which is not completely burned out of the exhaust gas is completely burned here, and the burned gas is dissolved in water with water solubility. . That is, while passing through the septic tank 502, carbon fluoride and carbon dioxide is dissolved in water and diluted. The diluted water is sent to a wastewater treatment plant for purification.
    [51] Flat glass is mostly used for building windows or windshields of automobiles. Glass windows of buildings and glass of automobiles are exposed to the atmosphere, and are exposed to the temperature and humidity of the atmosphere. The surface of the glass that has been exposed to weathering for a long time is blurred, thereby preventing the transparency from being lowered.
    [52] In order to prevent the quality of the product from deteriorating due to weathering of the produced glass during distribution, the product is packaged and the packaged product must be stored in a space where humidity and temperature are constantly controlled. Since the weathered glass does not occur weathering has the effect of reducing the cost of maintaining a constant temperature and humidity of the space for storage.
