With the continuous advancement of industrialization, industrial vacuum equipment is more and more widely used in various fields. Among them, as a kind of industrial dust collection equipment, bag filter is widely used in various industrial dust control fields because of its advantages of high efficiency, environmental protection and energy saving. This article will introduce the principle, classification, application and maintenance of bag filter in detail.
First, the principle of bag filter.
The bag filter is a dry dust collector, the principle of which is to use the filter material (i.e., the bag) to filter the dust particles in the dust-containing gas, so that the dust particles are blocked on the surface of the bag, so as to achieve the purpose of purifying the gas. When the dust on the surface of the bag accumulates to a certain extent, the dust is removed by the ash cleaning device, and then discharged through the ash discharge device.
2. Classification of bag dust collectors.
1.According to the cleaning method, it can be divided into: mechanical vibration type, reverse air flow cleaning type, pulse injection type, etc.
2.According to the filtration method, it can be divided into: external filter type and internal filter type.
3.According to the air intake mode, it can be divided into: lower air intake and upper air intake.
4.According to the structure, it can be divided into: open type and closed type.
3. Application of bag dust collector.
Bag filters are widely used in dust control in steel, electric power, chemical, cement and other industries. In these industries, due to the large amount of dust generated in the production process, if it is directly discharged into the atmosphere, it will not only cause serious pollution to the environment, but also cause harm to people's health. Therefore, the use of bag filter can effectively collect and process these dusts, protect the environment and protect people's health.
Fourth, bag dust collector maintenance.
In order to ensure the normal operation and service life of the baghouse, regular maintenance and maintenance are required. Specifically, it includes the following aspects:
1.Regular inspection: check whether the bag is damaged or falling off, and check whether the pulse valve, poppet valve and other components are working normally.
2.Cleaning and maintenance: Regularly clean up the dust inside and outside the equipment to keep the equipment tidy.
3.Replace the filter bag: When the filter bag is damaged or the life expectancy expires, the filter bag should be replaced in time to ensure the filtration effect and service life of the equipment.
4.Maintenance: Conduct comprehensive inspection and maintenance of the equipment on a regular basis to ensure the normal operation and use of the equipment.
In short, as an efficient and environmentally friendly industrial vacuum equipment, bag filter is more and more widely used in various fields. In order to ensure its proper operation and longevity, it needs to be regularly maintained and served. At the same time, it is also necessary to choose the appropriate type of bag filter according to different needs and application scenarios to achieve better use and environmental protection effects.
