What does the main technological process that dust catcher hop-pocket cleans have?

　　 The main technological process that dust catcher hop-pocket cleans:

1, clear ash: Use high frequency shake, will enter the bigger dirt particle inside filter bag wall to keep clear of entirely, do not meet intricate to fibrous prison spends generation to affect, hold filter bag good sex, of bilge easy come off quality.

2, chemical experiment processing: Collect hop-pocket sample, use professional instrument assay to detect filter bag is smeary composition, choose accommodative catharsis raw material thereby, of big limit clean filter bag and incorrect filter bag causes any harm.

3, medicaments immerses: Choose proper chemical preparation to immerse filter bag, keep clear of the bilge of oily be soiled inside filter bag aperture, the addition of big limit the permeability of filter bag can.

4, clean: Choose proper catharsis raw material to deserve strictly to compare. Microtherm water is cleaned, current is even, intensity moderate, do not have damage to filter bag.

5, stoving: Use 110 Celsius to control hot air drying, maintain the dimension stability of filter bag, changeless form does not answer bag of the filter after stoving shrink.

High temperature resistant amount of casing of hop-pocket dust catcher should take many hop-pocket to collect dust implement clear ash uses grey from line Qing Dynasty means commonly, alleged clear from the line ash, those who point to is the hop-pocket that undertakes clear ash, with the hop-pocket that moves normally segregation is shut undertake clear ash, after finishing, again automatic devoted moving dust catcher produces manufacturer.

Because of this casing amount less dust catcher is when clear from the line ash, because filter,the area changes bigger, cause boiler to run pressure to change accordingly bigger. And the dust catcher with casing more amount solved this problem relatively, the impact that moves normally to boiler is less also, can assure the stable negative pressure of boiler, and when be being maintained from the line when casing, the influence that moves to boiler also can fall to inferior.

All solder dots on the filter bag framework in dust catcher framework should solder firm

High temperature resistant course of hop-pocket dust catcher develops for years, at present hop-pocket collects dust implement already perfect maturity, received very wide application in large fire power plant. The article probed the development of hop-pocket dust catcher in boiler of refine sugar industry and applied situation, show a few points of pair of its type selecting and application with the applied example of 2 75t/h boiler.

High temperature resistant hop-pocket dust catcher also is called filter type dust catcher, it is dust catcher of a kind of dry type, the bag formula that it uses fiber to weave content is made filters component will catch collect to contain substance of grain of the solid in dirt gas.

Mine dust catcher has wet dust catcher and dry type dust catcher two kinds, wet the drawback that dust catcher has pollution 2 times and management is no-go, especially the character that the use water in the winter freezes easily was become be short of greatly situation; Operation of dry type dust catcher is simple, safeguard convenient, post collects dust rate is high,

High temperature resistant hop-pocket dust catcher is very tall to the requirement of filter makings quality, general filter expects need is imported, this raised the economic cost of the factory. Accordingly, of filter bag homebred changing development is the main factor that restricts development of hop-pocket dust catcher and general application currently, fulfil as soon as possible. Hop-pocket collects dust implement resistance is great, this also is the issue that we need to solve.

Remove dust the structure of hop-pocket basically is by upside casing mid casing is mixed bottom casing namely ash bucket, still have clear grey system and the partial composition that the orgnaization that discharge ash waits a moment.

A lot of part that begin to improve coal fired on one hand, use contain the coal with less sulfur, reduced the generation of harmful gas thereby; On the other hand, positive development removes dust technology, then hop-pocket dust catcher emerge as the times require. Hop-pocket collects dust implement the suiting to dust capability is very strong, it has a variety of structures in order to get used to the change of dust.
