Always check control pneumatic valve, electromagnetic pulse pneumatic valve as well as the action of the timer 2)

directly affect the soot cleaning effect. To prevent burning and explosion: cement rotary preheater of exhaust fumes, coal grinding equipment out of combustible materials such as waste gas containing a CO coal dust, dust concentration of its content, and a certain temperature under the condition of burning explosion accident will happen, not burnt dust removal equipment, also affected the normal operation of the production of the host, influence of the coke oven filter dust removal efficiency. 2 to prevent dust catcher internal short circuit. Because of the high dust concentration of dust source gases, such as g/m to prevent dewing: used to prevent the gas in bag indoor cooling below the dew point, especially under the negative pressure more attention should be paid to the use of coke oven collector. Because of its shell often have to leak into the air, bag room temperature is lower than the dew point of gas and filter bag can be affected with damp be affected with damp, the dust is not loose, but thick paste adhesive on the filter bag, the fabric pore blocking, resulted from dust, coke oven collector pressure drop is too large, cannot continue to run, some paste bag can't dust removal. To prevent condensation, it is necessary to adhere to the gas inside the filter and its system are higher than the dew point temperature ~ ℃ (everywhere As the dew point temperature of kiln grinding machine ℃, often should check control pneumatic valve, electromagnetic pulse pneumatic valve as well as the action of the timer, etc. The failure of the pulse pneumatic valve rubber diaphragm is rare fault. Operating temperature should be above ℃ to ensure the good use effect of filter bag. The measures are as follows: (1) adding raw material heap. Cement production in all kinds of raw materials, fuel and mixed material moisture content, if on fixed pile relative, prevent the rain can reduce the water content of the material, it is an effective measure to reduce the material moisture. Southern Chinese cement plant this kind of situation is normal, but the material stack shed some small, some are not, therefore, caused some difficulties to the use of coke oven collector. 2 to reduce air leakage. Dust catcher ontology local aperture leakage, air leakage should be controlled in coke oven collector ontology. % the following. Dust catcher system in process equipment of air leakage, such as ball mill discharge outlet under airtight sealed discharging pneumatic valve, filter ash discharge the air leakage and piping flange connection of the pneumatic valve and so on, these are often ignored by the maintenance and management personnel, therefore, increased the unnecessary leakage air volume, worsen the terms of the operation of the coke oven collector.
