4 measures to stop condensation on pulse bag filter


(1) Reduce the air leakage phenomenon of pulse bag filter

1, During the process of production and installation of pulse bag filter, it is necessary to strictly implement the JC / T532 welding standard for welding, to eliminate the phenomenon of less welding and missing welding of the dust collector.

2. The unloading port of the pulse bag filter should adopt the air lock device with good sealing performance. At present, it is mainly based on pneumatic or electric lock valves. When necessary, two-stage wind locks can be used.

The leakage rate of a pulse bag filter should be controlled within the ≤3% range.

(2) Strictly control the water spray volume of the humidification tower

When the cooling device of the cement dry-line kiln adopts a humidifying tower, the water-spraying amount cannot be increased after unilaterally pursuing the cooling effect, and the water spray volume of the humidifying tower must be strictly controlled under the condition that the inlet temperature of the pulse bag-type dust collector is ensured. . The humidifying tower uses high-quality spray guns as much as possible to make the sprayed water fine and uniform, and achieve the best cooling and quenching effect with the least amount of water.

(3) Stable flue gas temperature in a smaller range

When the temperature of the treated flue gas is too high, it is necessary to immediately reduce the operating temperature, cool air and other cooling measures; when the flue gas temperature is low, it is necessary to immediately increase the operating temperature and other warming measures so that the flue gas temperature can be stabilized in the prescribed range Inside, ensure the normal and stable operation of the dust collector and reduce condensation.

(4) Reducing the temperature difference and de-wetting of the pulsed gas and smoke inside the dust collector

Currently, the commonly used gas supply routes for compressed gas in China are: compressed air - gas storage tank - gas supply triple unit - air bag - pulse valve This gas supply has the advantages of low investment and simple equipment, but when the outside air temperature is over When it is low, the compressed gas is insufficiently treated and it is likely to cause condensation.

Airslide Fabric

Air slide fabrics are used for the pneumatic conveying of fine dry powdery products such as cement. The air slide cloth divides the air slide into upper and lower chambers. The chamber is inclined at as low as 1.5°.Compressed air is injected into the lower chamber which then goes through the media and “fluidises” the cement powder. The cement then behaves like a fluid and “flows” down the length of the chamber.

TIPS

Airslide is a semi-permeable textile cloth which allows air to pass through but not the products.

Airslide Fabrics other names are: airslide fabric,air slide fabric,air permeable fabric,fluidising fabric,fluidizing fabric,air slide belt,air slide canvas,aeroslide,airslide membrane,aeration pad, aeration fabric.air slide fabric in shipping,air slide fabric for silos,chute bottoms.
