The bag-type dust removal method is widely used, and has the advantages of simplicity, convenience and large flux. However, the application field of the current large-flux bag-type dust collector is mainly similar to that of gas dust removal and emission reaches the standard. However, in the case where the filtered gas is required to contain no macroscopic impurity particles, it is difficult to directly use the existing dust collector. For example, if the solid powder formed after the filtration of the large flux gas is completely dissolved and then filtered, the larger solid sample may be inspected and may be judged to be unacceptable as long as there are two black spots or impurity particles barely visible to the naked eye.
The above problems are not completely solved simply by choosing a filter cloth of suitable filtering precision itself, since at present there is also a problem in the construction of the main equipment that may leak or generate impurity particles, for example cloth bags are blocked by simple steel rings on perforated plates, such gaps are not closed by special forced pressure, nor are designs sealed by using sealant, and these junctions and keels that prop open the cloth bags are all on the product side after having passed through the filter cloth, are not left or generated when manually installed and maintained, and the back blowing to remove dust layers accumulated on the filtering surface is usually also carried out on the product side, these structures and activities may become potential sources of impurity particles, thus being able to meet the usual atmospheric emission standards, but being difficult to meet the higher product quality standards if used for other e.g. high end product manufacturing. Moreover, the devices of the prior art are designed to be fixed in one way of use and cannot be changed to another way of use.

1. when the device is in the running mode of the structure shown in fig. 1, the fixation, the back suction and the blocking removal and the like of the cloth bag are carried out on the raw material side, and the product side of the other side of the filter cloth does not need any manual structure or operation, so that the possibility of producing impurity particles or polluting products is avoided to the greatest extent.
2. When the device is in the running mode of the structure shown in fig. 1, the filter bag can be obviously collapsed by using short-time negative pressure in the blocking removal process, the filter bag is inflated again by normal working air flow after the negative pressure is cut off, and obvious blocking removal effect can be generated by the alternative obvious change of the shape of the filter bag.
3. According to the invention, the assembly mode can be simply changed according to the changed condition, namely the hole plate layer 3 is kept unchanged, the first cabinet body and the second cabinet body are connected after being transposed and turned, and the filter bag is installed to be correspondingly changed, so that the structure (figure 1) of the invention can be changed to the common use mode (figure 2) in the prior art, and the invention has wider adaptability.
