Pulse bag type dust collector mainly uses pressure, The spray pressure is an important parameter of the ash cleaning system of the pulse bag filter. The injection pressure of the bag filter refers to the compressed air pressure of pulse injection. After the pressure drop of the bag filter is limited, the higher the injection pressure, the greater the processing capacity. With the same injection distance and injection time, the injection pressure increases and the inlet dust concentration increases accordingly. However, if the injection pressure is too high There will also be excessive ash removal, which will affect the purification efficiency, that is, the bag dust collector will suddenly "ash out", at the same time, the gas consumption increases and energy is wasted. According to the air supply, we divide the pulse bag type dust collector into high pressure, medium pressure and low pressure ash cleaning systems. According to the internal pressure of the airbag, the pulse valve is divided into high pressure valve and low pressure valve.
The pulse bag type dust collector mainly uses the compressed air in the pressure air bag as the ash cleaning energy. When the pulse bag type dust collector is started, the pulse airflow reverses the pulse vibration from the top to the bottom of the filter bag. The dust layer separated from the outside of the filter bag The ash bucket that enters the dust collector is blown by pulse. If the pressure or flow is insufficient and the air flow is too weak, the dust removal force cannot reach the bottom of the filter bag. If the dust layer cannot be peeled off in time, part of the dust is formed, the equipment resistance increases, and the filter bag load The unevenness shortens the service life of the filter bag. On the other hand, if the dust removal strength is too strong, once the fine particles immersed in the surface of the filter bag will be blown out of the surface, resulting in a "secondary Yangchen" phenomenon. Therefore, the filter bag may also crack due to excessive vibration and friction with the cage bone. Therefore, whether using high pressure, medium pressure or low pressure compressed air sources, the dust removal power and flow of the equipment must be based on process characteristics, smoke and filter Reasonable configuration.
When designing the dust cleaning system, the consumption process (temperature range, temperature change, dew point, temperature, flue gas particles, flue gas composition, etc.) should be comprehensively considered.) Site environment (strict air supply, equipment site size, etc.) and filtration Material properties (whether the material, film can be coated, external treatment, abrasion resistance, flexural strength, tension range, etc.) Confirm the cleaning pressure or cleaning process, and stop cleaning.
