Pulse jet bag filter condensation solution

1, To reduce leakage phenomenon precipitator
(1) dust in fabrication and installation process, must strictly enforce the JC / T532 welding standards for welding, to prevent dust and less welding, weld phenomenon.
(2) dust discharge opening should be good sealing performance air lock devices, mainly in pneumatic or electric lock air valve based. When necessary, can be dual-stage air lock device. A pulse jet bag filter air leakage rate should be controlled in ≤3% range. 2, Strictly control the amount of water conditioning tower When the cement kiln dry normal cooling device using the conditioning tower, not one-sided pursuit of the cooling effect and increase the amount of water necessary in ensuring the precipitator inlet temperature strictly controlled amount of water conditioning tower. Humidifier tower as far as possible the quality of the gun, so that a uniform fine spray of water, with the least amount of water to achieve the best cooling quenching effect. 3, Stable flue gas temperature in the range of smaller When the flue gas of high temperature treatment, to be taken immediately to reduce the operating temperature, and other cooling measures put cold; when the flue gas temperature is low, to be taken to improve the operating temperature raised immediately. Within the flue gas temperature can be stabilized at a predetermined range, to ensure the normal and stable operation of dust and reduce condensation. 4, Reducing the temperature difference between the gas dehumidification process pulse jet dust collector internal flue gas The current common domestic gas supply routes compressed gas are mainly: compressed air – tank – triple gas source – air bag – pulse valve. This air supply with less investment, simple equipment advantages, but when the outside air temperature is too low, insufficient compressed gas processing, easy to condensation. When the outside air temperature is too low and the air compressor gas station distance, the supply line can be used: compressed air – tank – triple gas source – air dryer – air heater – air bag (gas bag laying insulation material) – pulse valve. This dehumidified air supply fully, completely, a small pulse jet dust collector internal flue gas temperature, difficult to produce condensation. When Pneumatic gas station not far from the gas source FRL air filter to meet the dehumidification needed, just pay attention to the air filter near the air bag at the can, thus eliminating the need for this part of the air dryer. When the temperature is too low, gas pipes, the air bag and pulse valve must be insulated to prevent condensation and dust air condensation. 5, Strengthen precipitator insulation measures Precipitator housing insulation measures must be taken, the general use of rock wool insulation dust, aluminum plates, pearl swelling rocks low thermal conductivity, good insulation properties, low water absorption, good heat resistance of insulation materials. The thermal conductivity of the material is generally not more than 0.23W / m. K. The thickness of the insulation material should be based on geographic location, local annual minimum temperature, annual average temperature depending on the specific can be determined according to the formula “Control unit heat loss law”.
