Adsorbed water treatment tank 420 is connected.
    [42] In addition, the centrifugal separator 210 and the exhaust fan 400 are integrally connected to the rotating shaft 220 so as to be integrally rotated when the driving motor 400a is driven.
    [43] The water treatment tank 420, the second nozzle 420b of the multi-stage is installed to gradually reduce the water particles are injected from the lower side to the upper side, the discharge pipe 420a is connected to the upper, the second nozzle ( 420b is made of a configuration that is connected as a water supply pipe (300a) branched to the water tank (300).
    [44] Reference numerals 200a and b denote drain pipes and discharge holes for resupplying water in the chamber to the water tank 300, and 220a denotes bearings for supporting the rotating shaft 220.
    [45] Referring to the operation of the present invention made of such a configuration as follows.
    [46] As shown in Figure 2 to 6, when the smoke is generated in the combustion device 100 including the harmful gas after the digestion of the material is delivered to the chamber 200 through the input pipe 120.
    [47] At this time, through the reagent inlet (120a) is connected to one side of the inlet pipe 120, the reagent reacts with the harmful substance is introduced, the reagent inlet (120a) is connected to the water tank 300 and directly mixed with water You may use it.
    [48] In addition, the smoke introduced into the chamber 200 forms the resonance region 270 through the first and second blades 230 and 240 of the rotating shaft 220 connected to the driving motor 400a. The resonant zone causes the harmful gas contained in the smoke to metathesize and neutralize with water and reagent.
    [49] The formation of the resonance region 270 by the resonance forming means 205 will be described in detail.
    [50] The resonance forming means 205, the pressure of the fluid flowing in the forward direction by the first blade 230 on one side and the pressure of the fluid flowing in the reverse direction to the first blade 240 on the other side is kept uniform The resonance region 270 is formed in the first and second blades 230 and 240.
    [51] At this time, the second blades 250 are installed between the first blades 230 and 240 to form a reaction force directed to the first blades 230 in the fluid toward the shaft center, and at the same time the Reaction force directed to the first blade 230 is formed by the second blade 260.
    [52] As a result, a resonance region 270 is formed on the second blades 250 and 260, and in the resonance region 270, the decomposition of harmful gas by the mixture introduced through the first nozzle 310 is performed. The process of causing neutralization at the same time is easy.
    [53] In addition, the inclination angle of the first blade 230 is smaller than the inclination angle of the other first blade 240 so that the flow pressure is increased so that the fluid flows into the resonance region.
    [54] In addition, a plurality of first nozzles 310 connected to each other through the water tank 300 and the water supply pipe 300a are installed inside the chamber 200 to spray the particulate mixture inside the chamber 200. This allows metathesis and neutralization of the gas.
    [55] In addition, at the inner diameter side of the chamber 200, which is the outer side of the first blades 230 and 240, the stop jaws 340 are formed in the circumferential direction to minimize the fluid flow for resonance formation by changing the flow direction of the fluid. It is possible to form a reliable resonance region.

    [59] As described above, the smoke eliminating device having the above configuration is one-stage double decomposition and neutralization in the resonance region installed inside the chamber 200, and is purified again by a water treatment tank, and only the clean gas is discharged into the air to be discharged by the combustion gas. Air pollution may be prevented, and a multi-stage resonant zone may be formed and processed in the chamber 200 according to the fluid introduced therein.
    [60] On the other hand, the control method of the present invention smoke purification apparatus shown in FIG.
    [61] Combustion gas is introduced into the inside of the chamber through an input pipe connected to the combustion device, and the chamber is provided with a plurality of braids inside the chamber to have a fluid flow in one direction.
    [62] At this time, the inlet pipe connected to the exhaust device is installed in contact with the chamber to simultaneously supply the combustion gas to the inside of the chamber to be heated to a temperature of 40 ~ 60 ℃.
    [63] Subsequently, inside the chamber, a plurality of braids having different diameters and inclined directions are respectively connected to the same rotational shaft to form a plurality of resonant regions, and at this time, one of the braids having a fine angle difference according to the flow direction of the fluid is provided. To have fluid flow into the furnace.
    [64] Then, a mixture of soda, acetic acid, calcined water, ammonia water, and the like diluted in water is supplied to the inside of the chamber through a pump.
    [65] The mixture introduced through the nozzle inside the chamber reacts with the harmful substances in the smoke in the resonance zone to metathesize and neutralize the harmful substances in the smoke.
    [66] Subsequently, the liquid neutralized by the mixture is collected in the reservoir through the bottom line, and the smoke to be purified is discharged through a blower installed at one side of the chamber.
    [67] Such a purification method will be described in detail by way of examples.
    [68] Example
    [69] A plurality of braids are coupled to the rotating shaft to form a resonance region by combining a first blade having a long radius and a second blade having a short radius inside the chamber, and the rotating shaft has a rotational speed corresponding to the amount of exhaust gas introduced thereto. The rotation speed is rotated at 1200 ~ 2200rpm.
    [70] And, the number of blades of the braid is 3 to 4, the inclination angle of the front braid having a long radius is 50 to 70 degrees, the inclination angle of the rear braid is 50 to 75 degrees, the inclination angle of the front and rear second blade having a short radius is 40 degrees to 50 degrees each.
    [71] At this time, the rotational speed of the rotating shaft is appropriately adjusted by the amount of the discharged gas is injected, when the number of the applied braid is generally less than 3 to 4, the rotational speed should be increased, when the number of blades is more than the rotational speed It should be reduced, and in this state, the best resonance region can be formed.
    [72] The first blade inclination angle having a long radius and positioned in the forward direction of the fluid is inclined to have a fluid flow in a forward direction, and the inclination angle is inclined to have a direction of 50 to 70 degrees in a clockwise direction on the horizontal line. The rear first blade inclination angle opposite to the first blade is formed to have an inclination angle of 50 to 75 degrees counterclockwise on the horizontal line to have an air flow in a direction opposite to the fluid flow.
    [73] At this time, the speed reduction reduction motion and the constant speed motion formed by the long radius first braid and the short radius second braid become equal to the sum of the parallel linear motions, thereby causing a resonance shape.
    [74] The desired braid angle of the long radius is reduced from 50 to 75 degrees or more, and the throughput is reduced, and the first braid is formed to have a predetermined angle difference.
    [75] In addition, when the inclination angle of the second braid of the short radius is greater than or equal to 40 to 50 degrees or less, the force for pushing the fluid toward the first braid of the long radius increases or decreases, thus breaking the balance of the force, making it difficult to form resonance. do.
    [76] Then, the mixture was put into the chamber is kcl- 20g, ca 2 (OH) 2 in water 100㎏ - consists of a mixture of 10g - 50g, AlOH - 20g, CH 3 COOH.
    [77] In addition, the mixture is put into the chamber with respect to the water 1000㎏ Na 2 Co 2 - consists of a mixture which is added 140g - 100g, CH 3 COOH - 10g , (OH 2) - 750g, NH 3 H 2 O.
    [78] In addition, the installation angle of the nozzle is provided so as to be positioned at 29 degrees clockwise on the horizontal line and 158 degrees counterclockwise.
    [79] Further, the installation angle of the nozzle is more preferably provided so as to be positioned at 45 degrees 170 degrees 280 degrees in the counterclockwise direction in the lowermost direction, respectively.
    [80] The smoke purified by the control method of the smoke purification device is treated as shown in Table 1.

    [83] Thus, by treating the harmful gas contained in the smoke through a process such as decomposition, metathesis, neutralization and saturation, the neutralized final treatment unit is discharged and the amount of carbon monoxide, carbon dioxide and sulfuric acid contained in the smoke is minimized.
    [84] As described above, according to the present invention, the pollutant contained in the extinguishing gas is decomposed and neutralized in a resonance state to minimize the emission of smoke and pollutants after combustion, and the neutralization proper state is achieved by a simple configuration that increases the resonance forming means inside the chamber. Maintaining simultaneously performs metathesis and neutralization saturation.
    [85] In addition, there is no need to periodically input and discharge gas filtering components or clean the inside of the chamber, thereby improving operation efficiency and minimizing maintenance costs.
    [86] In addition, it removes carbon dioxide, carbon monoxide, sulfuric acid, etc. from the combustion gases, as well as lowers the gas content of Knox.
