In order to assure the well utilization effect of bag filter and avoid moisture condensation, we should make the air temperature in filter higher than dew point. The following measures are useful to realize the above assurances. Once we use the coal slime dryer, all kinds of raw material, fuel and mixed material should be kept in shed house. Or else, the water content in material would increase once being exposed to the rain. Air leakage caused by bag filter itself should be controlled at no more than 3.5%. Parts related with air leakage in bag filter include: airtight discharge valve and flange connection, etc. Operators are easy to overlook the checks for these parts.

In order to maintain the well operation of bag filter and sludge dryer, we should pay much attention to the above parts. The dusty gas in bag filter should be distributed evenly. Or else, the vortex occurring in corners would cause moisture condensation. It is proved that suitable heat preservation measures can make the temperature difference become smaller between feeding mouth and discharging mouth of bag filter. In another words, heat preservation and waterproofing measures for bag filter is effective to avoid moisture condensation.

To improve the flue gas temperature of coal slime dryer or sludge dryer, we can take some heat preservation measures, for example installing heater in bag filter or allocating heating radiator in bag house.
