Precautions for daily operation and maintenance of Industrial Electrostatic Precipitator
In the daily operation of Industrial Electrostatic Precipitator, due to operating conditions will be some changes, or some failure, will affect the normal operation of the equipment and work performance, to be regularly checked and appropriate adjustments. Attention should be paid to the following questions:
1, running records
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, which can be based on the system pressure, inlet and outlet gas temperature, the main motor voltage , Current and other values and changes to determine, and timely discharge failure to ensure its normal operation.
2, safe
Industrial Electrostatic Precipitator should pay special attention to measures to prevent burning, explosion and fire accidents. In the treatment of combustion gases or high temperature gas, there are often incomplete combustion of dust, Mars, burning and explosive gases into the system, some dust has the nature of spontaneous combustion or charged. Should be well considered to take fire, explosion protection measures.
3, fluid resistance
U-type differential pressure meter can be used to determine the operation: If the pressure increases, means that the filter bag appears plug, filter bag with water vapor condensation, cleaning mechanism failure, ash fouling too much so clogging bag, gas flow increased Happening. Box or the division between the leakage phenomenon, the fan speed slow down and so on.
4, Industrial Electrostatic Precipitator to stop operating Notes
Before the Industrial Electrostatic Precipitator to stop running, in addition to the need to thoroughly clean, but also should pay attention to the following questions:
⑴ bag moisture condensation often occur in the room, which is containing moisture, especially after the combustion of the gas caused by cooling, so the system before cooling, the gas containing the exhaust, completely replaced by dry air, but also It is in the process equipment to stop running, the Industrial Electrostatic Precipitator exhaust fan should run for some time before they stop running.
⑵ in the long-term operation, to pay full attention to the fan cleaning, rust and other work to prevent dust and rain into the bearing. Before the cessation of operation, the ash should be ruled out of the ash. The cleaning mechanism and the drive part should be filled with oil.
⑶ in the bag filter to stop running during the regular short-term operation is to ensure the normal operation of the dust removal system maintenance methods.
5 maintenance
Always check the operation of the control valve, pulse valve and timer.
Pulse valve rubber diaphragm failure is a common failure, it directly affects the cleaning effect. The device is outside the filter, the bag built-in skeleton, to check the fixed filter bag parts are loose, filter bag tension is appropriate. So the oil mist and water droplets are required, and the oil-water separator must be cleaned regularly to prevent malfunction of the movement mechanism and the bag.
Industrial Electrostatic Precipitator dust removal effect of the advantages and disadvantages of a variety of factors, but mainly depends on the filter, Industrial Electrostatic Precipitator filter material is synthetic fiber, natural fiber or glass fiber woven cloth or felt. Place the cloth or felt into a cylinder or flat bag as needed. According to the nature of the flue gas, select the appropriate conditions for the application of the filter. In general, in the case where the flue gas temperature is lower than 120 ° C and the filter material is required to have acid resistance and durability, polyester flannel and polyester needle felt are often used. When the high temperature flue gas (<250 ° C) is used, Glass cloth; in some special circumstances, the choice of carbon fiber filter and so on.
