Daily precautions of bag filter dust collector

In the daily operation of bag type dust collector, due to some changes in operating conditions, or some failure, will affect the normal operation of the equipment and performance, it is necessary to be regularly checked and properly adjusted in order to extend the life of filter bags, reduce power consumption and recycle useful materials. The following is daily precautions of bag filter dust collector: 1. Running record Each ventilation and dust removal system must be installed and equipped with the necessary test instruments in the daily operation must be regularly measured and accurately recorded, this can be based on the system pressure, inlet and outlet gas temperature, the main motor voltage, current and other values and changes to judge, and timely troubleshooting, to ensure its normal operation. The problems discovered through the records are: the working condition of the cleaning mechanism, bag conditions (broken, paste bag, plug and other issues), and changes in system air volume 2. Fluid resistance U-type differential pressure gauge can be used to determine the operation: If the pressure difference increases, it means that the filter bag is clogged, water vapor condenses on the filter bag, the cleaning mechanism fails, the dust hopper clogs the filter bag and the gas flow increases, etc. If the pressure difference drop, means that there is a broken or loose filter bag, the inlet side of the pipeline blocked or the valve closed, leakage between the box or the sub-room, the fan speed slowed down and so on. 3. Safety Bag filter should take special precautions to prevent burning, explosion and fire accidents. In the treatment of combustion gases or hot gases, there are often incomplete combustion of dust, Mars, there is combustion and explosive gases into the system, some dusts have the property of spontaneous combustion or chargeability. At the same time, most of the materials of the filter media are inflammable, and the friction tends to accumulate static electricity. Under these operating conditions, there is a danger of burning and explosion accidents. The consequences of such accidents are often very serious. Should be well considered to take fire, explosion-proof measures, such as: (1) In front of the bag filter placed a combustor or spark catcher, in order to completely combust the incompletely-burned dust and gas or trap the spark. (2) To prevent the accumulation of static electricity measures, all parts of the conductive material grounded, or in the manufacture of filter media by adding conductive fibers. (3) Prevent the accumulation of dust, so as to avoid spontaneous combustion of dust and explosion.
