Dust bag bag bag bottom style

Select appropriate filter material for dust bag:
The selection of filter media should be based on the temperature, humidity, and chemical characteristics of the gas, as well as factors such as particle size, weight, shape, roughness, dust concentration, filtration speed, cleaning method, emission concentration, and the working system of the bag filter. In general, needle punched felt is used for pulse jet dust collectors, while machine woven fabric is used for fractional blowback bag dust collectors or mechanical vibration bag dust collectors.
Design a reasonable dust bag structure:
The structure of the filter bag should meet the requirements of the matched bag filter for filtering and cleaning dust, and be easy to install, sealed reliably, pursuing corresponding filtering area and good filtering state, easy to clean dust and avoiding wear as much as possible. Reasonable coordination with relevant components. The external filter type synthetic fiber filter bag should have a loose fit with the frame, and the external filter type glass fiber filter bag should have a tight fit with the small spacing vertical reinforcement frame; The internal filter bag should consider and design the tension of the filter bag.
Sewing technology of dust removal bag:
Craftsmanship: The sewing size meets the design requirements, and thermal shrinkage dimensions are reserved according to the type of filter material and usage temperature.
Equipment: The sewing needle spacing is reasonable, with no skipped or broken stitches, and the stitching meets the requirements.
Accessories, with reasonable coordination and no burrs or breakage that may damage the filter bag.
The entire filter bag has no defects such as small holes, yarn jumping, stains, etc., and is properly packaged to prevent damage or moisture during storage and transportation. Fiberglass filter bags should not be heavily pressed or stored for too long, otherwise it will affect their service life.
The correct usage method of dust bag:
a. Correct and serious installation

b. Reliable and effective dust cleaning
During the use of dust removal bags, the dust area gradually increases and the pressure difference rises. Effective dust cleaning and dust stripping should be carried out to maintain the pressure difference inside and outside the filter bag within the set range.

c. Prevent sudden abnormal situations
During operation, the bag filter should be prevented from sudden abnormal situations, such as sudden increase in gas temperature, entry of corrosive gases, or sudden decrease in gas temperature below zero, which may damage the filter bag due to factors such as temperature, humidity, chemical corrosiveness, mechanical wear or impact.

d. Equipment maintenance
If the dust removal bag is damaged, it should be discovered and replaced in a timely manner. The pressure difference of the bag filter should be observed regularly. If there is a malfunction in the dust cleaning, it should be eliminated in a timely manner. The ash unloading system should work normally. If there are changes in the process conditions of the dust removal system, the dust cleaning cycle or the working system of the bag filter should be adjusted in a timely manner.
