Operation, maintenance and transformation of electrostatic precipitator
The electrostatic precipitator uses electricity to separate the dust particles in the gas. This dust removal equipment has the advantages of high dust removal efficiency, good temperature resistance, large amount of flue gas treatment and high degree of operation automation. It has been widely used in cement plants. Here are some factors affecting the efficiency of electrostatic precipitator from the aspects of operation and maintenance.

Key points of bag filter design
The processing air volume determines the size of the bag filter. Generally, the processing air volume is the working condition air volume. Pay attention to the use place and flue gas temperature of the dust collector in the design. If the flue gas treatment temperature of the bag dust collector has been determined and the gas is cooled by dilution method, the treatment air volume should also consider increasing the amount of diluted air; Considering the process changes in the future, the design index value of air volume should increase the safety factor of 5% ~ 10% on the basis of normal air volume. Otherwise, once the process adjustment increases the air volume in the future, the filtration speed of bag filter will increase, which will increase the resistance of equipment and even shorten the service life of filter bag, which will also be the reason for the sharp rise of other failure frequencies. However, if the safety factor is too large, the investment and operation cost of dust collector will be increased;

How to prevent dust explosion of explosion-proof bag filter
Dust explosion is an oxidation reaction that is completed instantaneously under specific conditions when the dust particles suspended in the air are in full contact with the oxygen in the air. A large amount of heat is released in the reaction, resulting in the phenomenon of high temperature and high pressure. Any dust explosion must have three conditions: ignition source; Combustible fine dust; The dust is suspended in the air and reaches the limit range of explosion concentration.

Installation instructions of bag filter
The equipment must be unpacked for inspection at the installation site. Check the box number, equipment name, drawing number (or specification) and number of pieces one by one according to the packing list or other forms of delivery list, and record the parts, tools, accessories (or materials), factory certificate and other technical documents one by one. After the inspection, go through relevant procedures and keep them properly. If there is any damage, it shall be repaired and corrected in time.
