Industrial Electrostatic Precipitator Choose A Reasonable Cleaning Method
Industrial Electrostatic Precipitator Choose a reasonable cleaning method
The cleaning method Industrial Electrostatic Precipitator more categories, cleaning methods currently used dust bag of sugar used for the plenum pulse and line pulse jet, plenum pulse having a simple structure and easy maintenance, but using process, the cleaning effect is found unsatisfactory, the bag after cleaning, no significant decline in the resistance, for this clever sugar 1 # Industrial Electrostatic Precipitator crop during overhaul 2010, once the original pulse cleaning air box to Line spray pulse cleaning, cleaning effect after the transformation is more obvious, Industrial Electrostatic Precipitator resistance directly from 2000Pa down to 1000 ~ 1200Pa.
In the premise of ensuring adequate filtration area, the length of the bag should not be too long
General Industrial Electrostatic Precipitator design, the manufacturer based on site and cost considerations, it is recommended to choose a longer length of the bag. But in operation, we found that the choice of bag length of 7500mm Industrial Electrostatic Precipitator, the lower part of the bag cleaning effect is poor, resulting in decreased resistance after cleaning is not ideal. And the choice of length of 6050mm Industrial Electrostatic Precipitator, check the upper and lower parts of the cleaning effect is very small, clear resistance after cleaning significantly reduced.
Electrostatic Precipitator box number to be taken Industrial plurality of cleaning bag filter typically off-line cleaning method, a so-called off-line cleaning, the cleaning means is bag, and the bag is closed for normal operation of the separator cleaning, complete And then automatically put into operation. So the larger number of cabinets Industrial Electrostatic Precipitator off-line cleaning, due to changes in filter area larger, resulting in a corresponding change in boiler operating pressure. The large number of cabinet Industrial Electrostatic Precipitator relatively solve the problem, the impact on the normal operation of the boiler is relatively small, can guarantee the stability of the negative pressure of the boiler, and when the tank offline maintenance, the impact on boiler operation can also be To a minimum.
Off-line valves and bypass valves should be equipped with independent compressed air sources. In the early stage of the # 1 bag filter, a pulse valve leak has caused the Industrial Electrostatic Precipitator to be shut off due to all of the off-valve and bypass valves Serious positive pressure was forced to stop. And in the control of off-line valve and bypass valve gas source to an independent dual gas source, found that both off-line valve leakage or air compressor downtime are basically guaranteed to control the off-line valve and bypass valve in 30 minutes, Thus ensuring the safe operation of the boiler.
The bypass flue should be of the straight type
The use of the discovery of a Industrial Electrostatic Precipitator, such as the use of a vertically rising bypass flue, results in the formation of a buffer zone in the corner area so that the dust is prone to settle when the opening bypass time is longer, necessitating clogging the baghouse entrance. The use of straight flue, the smooth flow of flue gas, a good elimination of the problem.
Choose a reasonable, stable automatic control system
Industrial Electrostatic Precipitator is currently fully automatic control, because its operating conditions are directly related to the safe operation of the boiler, it must ensure safe and effective control of its operation, so in the choice of automatic control system to be careful, the proposed selection of more stable and reliable control system.
Industrial Electrostatic Precipitator is a dry filter device that is suitable for trapping fine, dry, non-fibrous dust, filter bags made of textile filter cloth or non-woven felt, the use of fiber fabric filtration on dust To filter, when the dust-laden gas into the Industrial Electrostatic Precipitator, the particles larger than the dust, due to the role of gravity sink down, fall into the ash bucket, containing smaller dust in the filter through the filter, the dust is blocked, So that the gas is purified.
Industrial Electrostatic Precipitator The advantages and disadvantages of dust removal are related to a variety of factors, but mainly depends on the filter. Bag filter is the 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. But also according to customer requirements for non-standard design transformation, tailored to your needs for your products.
