1. Vibration dust removal

The characteristic of this kind of dust removal method is that the kinetic energy applied to the dust layer is smaller than that of pulse blowing and reverse blowing type. It is a low-energy type of dust removal. Therefore, it is suitable for fabric dust filter bags.

2. Anti-air blow and dust removal

This kind of dust removal method generally uses fabric dust filter bag, but it can also use felt with lighter cloth weight, softness, and small scale change range. The hoisting, sewing and other procedures of the dust filter bag have requirements. If you do not pay attention, it will have a greater impact on the service life of the dust filter bag.

3. Pulse jet dust removal

The kinetic energy of this dust removal method applied to the dust layer is relatively high, which is a typical method of external dust removal. The dust removal force is very strong, and the residual amount of dust attached to the yarn of the dust removal bag is relatively small. The dust removal bag used is generally needle felt. Under the effect of pulse blowing, the dust removal filter bag will instantly become very large and the stress will be great, so use a filter material with strong resistance to tension. The dust collector bag often conflicts with the skeleton, so the dust filter bag with good wear resistance should be used.

4. Air ring spray dust removal

Due to the good dust removal function, the dust removal cloth bag has small pores and good wear resistance. In this way, when the blowing air ring reciprocates up and down, the dust-removing bag remains unchanged and will not fluff.

5. Pulsating back blowing dust removal

The kinetic energy exerted by this method on the dust lies in the center of the high-energy type and the low-kinetic energy type. The filter material of this kind of cloth-removing bag is soft and needs to have a certain strength.

6. Anti-air blow-oscillation dust removal

The dust removal kinetic energy applied to the dust layer is of low energy type. In the early days, most of the fabric dust bag was used. Nowadays, most needled felts are used. The primary factor is filtering speed. The weight of needled felt is 280/㎡~350g/㎡, the thickness is 1.0mm~1.3mm, and its air permeability is better.
