Abstract
The utility model discloses an industrial dust collector with echeloned filter cylinders. The industrial dust collector comprises a box body, filter cylinders, a pattern plate, an air inlet, an air outlet, a pulse valve, an air pocket and a pulse jetting pipe, wherein the box body consists of an upper box body, a middle box body and a lower box body; the upper box body is also called an air purifying box, and is provided with a jetting device and the air outlet; the air inlet is formed in the lower part of the middle box body, and the pattern plate is fixed on the upper part of the middle box body; at least two rows of the filter cylinders are arranged on the pattern plate, and each row comprises at least seven filter cylinders; the length of the filter cylinders is increased in an echeloned way along the air inlet direction according to an equal-difference rule, the filter cylinders of adjacent rows are in front and back alignment, and the row separation distance of the filter cylinders is kept equal; and the lower box body is also called a dust collection box for collecting dust after ash cleaning. According to the industrial dust collector, because the length of the filter cylinders of each row is increased in an echeloned way along the air inlet direction according to an equal-difference rule, the problem that the flow of treated gas and the ash cleaning flow of each filter cylinder in the conventional industrial dust collector are not uniform is solved, the filter cylinders at the back end of the dust collector are prevented from being damaged in advance, and the service life of the dust collector is prolonged.
Description
Technical field
The utility model relates to the industrial dedusting technical field, relates in particular to a kind of industrial dust arrester.
Background technology
The industry dust arrester is an equipment commonly used in the industry, is mainly used in solid, liquid substances such as reclaiming or handle each metalloid, nonmetal, oily, water in production and the transport process of industries such as iron and steel, power plant, nonferrous metallurgy, weaving, cement, chemical industry.As a kind of environmental protection equipment, industrial dust arrester can effectively prevent the harm of some occupational diseases, and in textile industry, can improve the quality of products, and can reclaim some expensive catalysts etc. in chemical industry.
Conventional industrial dust arrester adopts single import intake method more; And single import intake method is because air-flow has certain initial velocity when just having got in the dust arrester; Air-flow can produce one jet; Gas Jet can make air-flow concentrate on this zone when running into the rear end face of dust arrester, and is promptly little big away from the air inlet air quantity near the air inlet air quantity, claims that also the flow field is inhomogeneous.And the filter cylinder in the existing dust arrester is the equal length arrangement, and the gas flow that can cause each filter cylinder to be handled like this is unequal, makes dust catching efficiency lower.In addition, if things go on like this can cause and handle the damaged in advance of the big filter cylinder of gas flow, this has not only shortened the life-span of industrial dust arrester, has also increased the production cost of enterprise simultaneously.
Simultaneously; The nozzle of the deashing device in the conventional industrial dust arrester evenly arranges, and the gas during deashing also is to go into from a side-blown of air inlet, thereby the jetting pressure of each nozzle all is different with the flow of jetting; The jetting pressure of winding-up pipe rear end is big than front end with the winding-up flow; And the filter cylinder in the existing dust arrester is the equal length arrangement, so the suffered deashing energy of the filter cylinder of rear end will be bigger than the filter cylinder of front end, the filter cylinder deashing of rear end is more thorough; When Chalk-dust filtering next time, will attract more gas flow like this, increase relatively thereby cause filtering load.Time one is long, will the take the lead in breakage and have influence on service life of whole filter cylinder of the filter cylinder of winding-up pipe rear end.
Summary of the invention
The utility model problem to be solved provides a kind of novel industrial dust arrester, makes the processing gas flow and the deashing flow of each filter cylinder in the industrial dust arrester even, has avoided the filter cylinder of dust arrester rear end damaged in advance, has prolonged the service life of dust arrester.Simultaneously, it has also improved dust catching efficiency.
A kind of filter cylinder of the utility model is the industrial dust arrester that echelon is arranged; Comprise casing, filter cylinder, card, air inlet, air outlet, pulse valve, gas bag and pulse jet pipe; It is characterized in that: described casing is made up of upper box, middle casing and lower box; Upper box is also claimed the pure qi (oxygen) case, is provided with blowing device and air outlet; The bottom of middle casing is provided with air inlet, and its top is fixed with card, arranges two row filter cylinders on the card at least; Whenever walk to rare seven filter cylinders; The length of filter cylinder is equal difference rule echelon along the air intake direction to be increased, alignment before and after the filter cylinder of adjacent lines, and the column pitch of filter cylinder keeps equating; Lower box is also claimed disposal box, is used for the collection of dust behind the deashing.
The industrial dust arrester that this is novel; Because being equal difference rule echelon along the air intake direction, every capable filter cylinder length increases; Be that dust arrester rear end filter cylinder length is long than the front end filter cylinder, its filter area is also big than the front end filter cylinder, and has air quantity big problem in the little rear end of front end air quantity in the dust arrester; Therefore such arrangement mode can make the filtration velocity of each filter cylinder keep equal basically, thereby the air quantity that each filter cylinder is handled is even basically; It is little to exist front end nozzle winding-up air quantity during industry dust arrester pulse dust cleaning, and the big problem of rear end nozzle winding-up air quantity, filter cylinder length are the increase of equal difference rule echelon along the air intake direction can make the deashing energy of the unit are that each filter cylinder accepts equal basically.Therefore, this novel industrial dust arrester has solved each filter cylinder processing gas flow and the even problem of deashing mass flow discrepancy in the existing industrial dust arrester, has avoided the filter cylinder of dust arrester rear end damaged in advance, has prolonged the service life of dust arrester.Simultaneously, because the gas flow that each filter cylinder is handled is equal, improved dust catching efficiency.
