A. Take appropriate heating measures. As in the precipitator with far-infrared electric heater, electric heater, or in the bag of indoor add radiator, can be appropriately raise the flue gas temperature of the host. Strengthen the dust collector and dust removal system of temperature monitoring, in order to master the conditions of use of bag filter, prevent dewing.

2. Reduce the air leakage. The dust collector body section gap of air leakage, bag filter body air leakage should be controlled below 3.5%. Process equipment in the dust catcher system of air leakage, such as ball mill discharge outlet under airtight airtight discharge valve, filter the air leakage and piping flange connection of the ash discharge valve and so on, these are often ignored by the maintenance and management personnel, therefore, increased the unnecessary leakage air volume, worsening the operation condition of bag filter.

3. Add heap tent material. In cement production 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. Cement factories in the south of China this kind of situation is normal, but the material stack shed some small, some are not, therefore, caused some difficulties to the use of bag filter.
