Advantages and disadvantages: close to zero emissions, can meet the most stringent environmental protection standards.
Good dust removal, can provide higher ventilation, or can reduce the pressure difference.
The life of the filter bag is prolonged, the number of cleanings is reduced, and the equipment maintenance cost is reduced.
With higher air-to-cloth ratio, smaller dust collectors can be designed to reduce energy consumption when the pressure difference is reduced.
Dust removal cloth bags are roughly divided into three categories in terms of temperature. Normal temperature types such as polyester needle-punched felt bags, anti-static dust-removing cloth bags, easy-to-clean dust-removing cloth bags, etc. Oil needle felt, high temperature products such as Metas dust bag, flumesi cloth bag, glass fiber needle felt filter bag, PPS acid and alkali resistant cloth bag, etc. The choice of dust bag should be based on air
The temperature, humidity and chemical characteristics of the body; the size, weight, shape, dust concentration and filtration speed of the particulate matter, the dust removal method, the emission concentration and the working system of the bag filter.
Under normal circumstances, the pulse jet bag type dust collector chooses needle felt, and the sub-chamber blowback bag filter or mechanical vibration bag filter chooses woven cloth. If the working condition is high temperature, it needs to be acid and alkali resistant and humid. You can choose high-temperature products, such as coated fluomex, etc.There are many factors to consider when choosing a dust bag.
1. According to the cross-sectional shape of the dust filter bag, it is divided into flat bags (trapezoid and flat) and round bags (cylindrical).
2. According to the way of air inlet and outlet, it is divided into: lower air inlet and upper air outlet and upper air inlet and lower air outlet and direct current type (only limited to flat bag).
3. According to the filtration method of the dust filter bag, it is divided into: external filtration and internal filtration.
4. According to the temperature tolerance of the dust filter bag, it can be divided into high temperature type, medium temperature type and normal temperature type.
5. Application areas Application areas: ironworks, steelworks, ferroalloy plants, refractory plants, foundries, power plants, cement plants, chemical plants, grain processing plants, carbon black plants, aluminum plants, etc.
