Baghouse operation (2)

Daily operations In the daily operation of the bag filter, since the operating conditions, certain changes occur, or some failure, will affect the normal operation of equipment status and performance, should be regularly inspected and appropriate regulatory purpose is to extend filter bag life, lower power consumption and recovery of useful materials. Attention problems are: 1, running record Each ventilation and dust removal system voltage and must be installed with the necessary test instruments, in the daily operation must be regularly measured and accurately recorded, which according to the system pressure, inlet and outlet gas temperature, the main motor and current values and the change to be judged, and timely discharge failure to ensure their normal operation. Problems found are recorded by: the work of cleaning agencies, the bag of condition (damaged, paste bags, clogging and other issues), as well as changes in the system of air volume and so on. 2, fluid resistance U-type pressure meter can be used to judge the operation: As pressure increased, which means the bag clogging, water vapor condenses on the bag cleaning agencies fail, resulting in excessive fouling clogged hopper bag, such as increased gas flow Happening. The reduced pressure means that there has been broken or loose bag, side air intake duct blockage or valve closed. Leaks, slow down the fan speed, etc. between the various sub-cabinet or room. 3, security Baghouse pay special attention to measures to prevent fire, explosion and fire accidents. When dealing with high-temperature combustion gas or gas, often incomplete combustion of dust, sparks, and explosive combustion gases from entering into the system, some of the dust has Spontaneous ignition properties or charged, while the majority of the filter material and are flammable and prone to the accumulation of static friction, under such operating conditions, there is a burn, an explosion hazards, and the consequences of such accidents are often very serious. We should consider taking a good fire, explosion measures such as: ⑴ set the combustion chamber or Mars trap in front of the precipitator, so that the incomplete combustion of gas incomplete combustion or dust and sparks trapped down. ⑵ take measures to prevent the buildup of static electricity, the various parts of the ground with a conductive material, conductive fibers or added during filter manufacture. ⑶ prevent dust accumulation or accumulation of dust in order to avoid self-ignition and explosion. ⑷ people enter the bag house or pipeline inspection or overhaul before, be sure to ventilation, to prevent CO poisoning
