Description
Technical field
The utility model belongs to technical field of dust removal equipment, more particularly, to a kind of self-priming of interior filter suction type dust arrester
Formula dedusting controlling organization.
Background technology
As industrial development and the raising of people's environmental protection consciousness, various dedusting technologies are developed by people
Come, various cleaners also just arise at the historic moment.Wherein, sack cleaner be widely used in the industry purify metallurgy, mine,
Dusty gas caused by the industries such as chemical industry, cement, generating, grain processing.The operation principle of sack cleaner, it is by ash-laden gas
Body is introduced into deduster and passes it through the filter bag in deduster, and grit is i.e. intercepted and stays in filter bag surface, forms one
Dust layer.Pure air then passes through filter bag and flows out deduster.When sack cleaner filters, filtered airflow is by the outside of filter bag
Flowed to through filtrate inside filter bag, grit is attached on the outer surface of filter bag.After a period of time is run, bag-type duster filtering bag
It is more and more thicker to meet the dust layer of dirt surface accumulation, increases the drag losses of deduster.Therefore, when sack cleaner runs one section
Between after, it is necessary to carry out deashing.
The purge mode of existing sack cleaner is mainly removed using mechanical rapping cleaning dust sack cleaner, blowback Windsock type
Dirt device, pulse blowing bag type dust precipitator.Mechanical rapping cleaning dust sack cleaner simple structure, it is reliable, but deashing effect is not
Uniformly, relatively low filtration velocity can only be allowed, and deashing tends to damage filter, destroys primary dusts layer.Blowback wind sleeve
For formula deduster in whole filter overdraught distribution uniform, vibration is not violent, filter is damaged it is smaller, but deashing effect compared with
It is weak, it is allowed to which that filtration velocity is relatively low.Pulse blowing bag type dust precipitator is that pulse jetting deashing mode is of short duration by pressure-air
Time is blown at a high speed filter bag, generation and the reverse blowback air-flow of filtered airflow, makes to produce impulsive inflation shake, filter bag wall in filter bag
Very high outside acceleration is obtained, so as to shake off dust.This mode belongs to dynamic deashing.The purge mode of above-mentioned pulse jet is
The dust layer for being attached to filter bag surface is set to come off by the change of filter bag profile.But because the deashing time is short, as compression is empty
The transmission effect of gas reduces with the increase of distance, and the dust stratification of some parts will be difficult to clear up, and the dust stratification of residual influences
Deashing, dust removing effects.And long-term, deformation repeatedly can cause the fatigue for accelerating filter bag, be significantly reduced filter bag uses the longevity
Life.Because the cost of filter bag occupies larger proportion in whole deduster, and the quantity of filter bag is very big, changes filter bag extremely
Inconvenience, therefore the flimsy problem of filter bag seems very prominent, in addition, pulse blowing bag type dust precipitator is required for setting for filter
A supporting bag cage is put, the bag cage needs periodic inspection and replacing, inconvenient for use, with high costs.
In order to solve the problems, such as that prior art is present, people have carried out long-term exploration, it is proposed that miscellaneous solution
Scheme.For example, Chinese patent literature discloses a kind of inward flow filtration-type dust-filtering equipment [application number：201210213565.9], bag
Include：Casing；Air inlet and air outlet；Filter fixed seat；The filter being fixed in filtering fixed seat；It is arranged on above filter
Injection system；The ash storage box being arranged on below casing；It is characterized in that：Described injection system includes compressed air source unit and injection
Pipeline；Air-flow is from compressed air source unit by injection tube road from top to bottom to filter port.
Such scheme solves the problems, such as existing filter plant deashing inconvenience to a certain extent, is carried out using injection system
Deashing, but each filter is required to individually be equipped with injection system in the program, so undoubtedly adds equipment cost, and
Still there is reliable low, the problem of inconvenient is overhauled.
The content of the invention
