![]() Method of using electric filter in production of phosphorus
专利摘要:
The invention relates to a process for operating a lead-in-device receiving a conductor which passes through the cover of an electrical precipitation apparatus down to its electrode system. A portion of the conductor is encircled by an insulator which is radially spaced therefrom and of which the upper end provides support for a structural component having the conductor gas tightly passed therethrough. The space inside the insulator receives a sealing gas which is maintained under a pressure higher than that prevailing in the electrical precipitation apparatus. The sealing gas used for operating the device is a gas mixture consisting of an inert gas and at least 10 volume % of methane. 公开号:SU1169522A3 申请号:SU802901945 申请日:1980-04-01 公开日:1985-07-23 发明作者:Эберт Ханс;Кербер Ханс;Квек Роберт 申请人:Хехст Аг (Фирма); IPC主号:
专利说明:
This invention relates to the electrical purification of gases produced in the production of phosphorus. The closest to the invention in its technical essence and the effect achieved is a method of operating an electrostatic precipitator used in the production of phosphorus, including a system of discharge electrodes under voltage, and a device for supplying voltage to the system of corona electrodes, which is supplied with a seal pressure gas is the highest pressure in the electro filter p J. The disadvantages of this method are the short lifetime of the electro-filter and the instability of the efficiency. The purpose of the invention is to increase the service life of the electrostatic precipitator and to stabilize its efficiency by preventing the arc from damaging the insulating parts in the voltage supply device to the system of corona electrodes. This goal is achieved in that according to the method of operation of the electrostatic precipitator used in the production of phosphorus, including a system of corona electrodes, which are under voltage, and a device for applying voltage to the system of corona electrodes, into which pressurizing gas is applied, above pressure in an electrostatic precipitator, a gas mixture consisting of an inert gas and at least 10% by volume of methane is used as a sealing gas. In addition, a gas mixture containing up to 90% by volume of methane is used; The inert gas may additionally contain carbon dioxide. 222 In this case, the product of combustion of natural gas with air is used as the inert gas in the stoichiometric ratio between hydrocarbon and oxygen. In addition, a mixture containing methane in the form of natural gas is used. With the introduction of the proposed method, the surface corrosion rate in the electrostatic precipitator is about 1 mm / year, which is acceptable. The deposits in the electrostatic precipitator consist of dry, easily removable dust. The degree of ionization of the sealing gas is so insignificant that no electrical discharges occur at the location of the insulating parts. When carrying out the proposed method under conditions when the electrostatic precipitator is exposed, for example, to a phosphorus furnace gas mixture passing through it, the calorific value of methane contained in the sealing gas does not disappear. The dense gas is mixed in the electrical separator with the gases mainly from vaporous phosphorus and carbon monoxide. After phosphorus is washed out of this mixture with water, a gas mixture is obtained consisting of carbon monoxide, methane and inert gas, which is used as flue gas and can be burned. When the content in the sealing gas is at least 10 vol.% Methane gas. the mixture is practically not ionized at operating voltages in an electrostatic precipitator up to 60 kV. Moreover, the metal surface does not corrode. In particular, the use of a gas mixture with a methane content of up to 90% by volume gives good results.
