How to make the filter bag more useful?

Because the filter bag is often leaked into the air, the gas temperature of the bag room is lower than the dew point, and the filter bag will be moisture, resulting in dust no longer loose, but adheres to the filter bag, causing the fabric holes to block the eyes of the fabric hole, forming the ash clearing into an invalidation failure , During the drop of the dust collector too much, it was unable to continue working, and some paste bags could not dust. In order to prevent the dew, the temperature of the gas in the dust collector and its system must be higher than its dew point at 25 ~ 35 ° C (such as the dew point temperature of the kiln grinding machine 58 ° C and the working temperature above 90 ° C) to ensure that the filter bag is good Application effect. The method of filter bag manufacturers is as follows:

1) Increase raw material stacks. The water content of various raw materials, fuels and mixed materials in cement production is different. If it is placed in a shed to prevent rain from soaring, it can greatly reduce the moisture content of the material. This is a method of effectively reducing material moisture. Essence The situation of the southern cement plant is relatively ordinary, but some of the sheds of the material piles are too small, and some are not, so it brings some difficulties to the application of the cloth bag dust collector.

2) Reduce leakage. There is a leakage of the dust collector's body. The leakage of the process equipment in the dust removal system, such as the closed ash unloading valve of the grinding machine, the wind leakage of the closed ash valve under the dust collector, and the pipeline flange connection, etc., is often ignored by the protected managers, so that the bag -type dust removal The working environment of the device deteriorates.

3) The dust -containing gas should be evenly distributed in the dust collector to prevent the vortex from the corner of the dust collector and reduce the amount of gas, which constitutes a local low temperature to form a dew problem.

4) Do a good job of warming and rain -proof work everywhere. Verifications, good insulation measures can make the pocket dust collector in and export temperatures very differently, which is an effective measure to prevent exposure.

5) Adopt appropriate heating methods. For example, there is a far -infrared electric heater, an electric heater inside the dust collector, or adding a heating piece in the bag room, which can appropriately increase the host's smoke temperature.

6) Strengthen the temperature monitoring of the dust collector and the dust removal system, master the application of the bag dust collector to prevent the occurrence of exposure.
