Detailed introduction of pulse bag dust collector for electric arc furnace. Bag dust collector, commonly known as bag dust collector, is widely used in many dust pollution industries. A detailed understanding of the classification and working principles of bag dust collectors will help you select dust collectors that can be used in various working conditions in an energy-saving and efficient manner.
In the daily operation of the bag dust collector, certain changes in operating conditions or certain failures will affect the normal operation and performance of the equipment. Regular inspections and appropriate adjustments are required to extend the filter bag life. The service life reduces power consumption and recovers useful materials. Issues that should be paid attention to include
Operation records
Each ventilation and dust removal accessory system must be installed and equipped with necessary test instruments. During daily operation, it must be measured regularly and accurately recorded. This can be done according to the system's Pressure difference, inlet and outlet gas temperature, voltage and current values and changes of the main motor are used to judge and eliminate faults in a timely manner to ensure normal operation.
Problems discovered through records include the working conditions of the dust cleaning mechanism, the working conditions of the filter bags, and changes in the air volume of the system.
Fluid resistance
A differential pressure gauge can be used to judge operating conditions. For example, an increase in pressure differential means that the filter bag is clogged. Water vapor is condensing on the filter bag and the ash cleaning mechanism has failed. Excessive dust accumulation in the ash hopper has blocked the air in the filter bag. Increased traffic, etc. A decrease in pressure difference means that the filter bag is damaged or loose, the air inlet side pipe is blocked, or the valve is closed. There is leakage between the box or each sub-chamber, the fan speed slows down, etc.
Safety
Bag dust collectors should pay special attention to taking measures to prevent combustion, explosions and fire accidents. When dealing with combustion gases or high-temperature gases, there are often incompletely burned dust, sparks, burning and explosive gases, etc. entering the system. Some dusts have the property of spontaneous combustion or are electrified. At the same time, most filter materials are made of materials that are easy to burn and friction. The accumulation of static electricity may cause combustion and explosion accidents under such operating conditions. The consequences of such accidents are often very serious. Fire and explosion prevention measures should be well considered, such as
⑴ Set up a combustion chamber or spark trap in front of the bag dust collector to completely burn the incompletely burned dust and gas or capture the sparks.
⑵ Take measures to prevent the accumulation of static electricity. All parts should be grounded with conductive materials or conductive fibers should be added when the filter material is manufactured.
⑶ Prevent the accumulation or accumulation of dust to avoid spontaneous combustion and explosion of dust.
⑷ Before entering the bag room or pipeline for inspection or maintenance, people must be ventilated to prevent poisoning. Keda Environmental Protection has been established for 30 years, specializing in the production of dust collectors and accessories.
