主要有那些： With the rapid development of industrialization in recent years ,
bag dust collectors are used more in industrial production ,
so after the use of dust is required to make the bag dust collectors
have a better dust removal effect ,
the commonly used methods of bag dust collectors
are Those ones:
Gas cleaning: Gas cleaning is to blow back the filter bag with the help of high-pressure gas or the external atmosphere to remove the dust on the filter bag. Gas cleaning includes pulse spray cleaning, anti-blowing cleaning and anti-suction cleaning.
Mechanical vibration cleaning: divided into top vibration cleaning and middle vibration cleaning (both for filter bags), the rows of filter bags are periodically shaken by means of a mechanical vibration device to remove the filter Ash on the bag.
Manual tapping: Tap each filter bag manually to remove the dust on the filter bag.
The structure of the bag filter is mainly composed of the upper box, the middle box, the lower box (ash hopper), the ash cleaning system and the ash discharge mechanism. The performance of the bag filter is not only the correct choice of filter bag materials, but also the ash cleaning system plays a decisive role in the bag filter
. 袋式除尘器是把粉尘从烟气中分离出来的设备叫除尘器或除尘设备。 For this reason, the ash cleaning method is one of the characteristics to distinguish the bag type dust collector, and it is also an important part of the operation of the bag type dust collector . The
bag type dust collector is a device that separates dust from the flue gas, called a dust collector or a dust removal device. . The performance of the dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. The bag filter is a dry dust filter device. After using the filter material for a period of time, due to the effects of sieving, collision, retention, diffusion, static electricity, etc., a layer of dust has accumulated on the surface of the filter bag. This layer of dust is called the primary layer. During the subsequent movement process, the primary layer became The main filter layer of the filter material, relying on the role of the primary layer, the filter material with a larger mesh can also obtain higher filtration efficiency. With the accumulation of dust on the surface of the filter material, the efficiency and resistance of the dust collector will increase accordingly. When the pressure difference between the two sides of the filter material is large, some fine dust particles that have adhered to the filter material will be squeezed out. Reduce the efficiency of the dust collector.
