Abstract

The utility model relates to a dust removal device for controlling industrial flue gas pollution and aims to solve the problems in a conventional dust removal device adopting tandem type combined desorption as the technique principle that the fault points are more, the overhauling is inconvenient and the dust removal efficiency can not be sufficiently ensured. The dust removal device adopts a structural form that an electric dust removing region airflow distribution device, an electrostatic dust removal device, a cloth bag region airflow distribution device and a rotary jetting cloth bag dust removing device are sequentially arranged in the airflow direction. The utility model provides the electric-bag composite dust removal device which has the advantages that the novel tandem type structure is adopted, the structure is compact, the reliability of the electrostatic dust removal device is strong, the quantity of the pulse valves of the cloth bag dust removing device is less, the overhauling is convenient, the airflow distribution is even, and the dust removal efficiency is high.

Description

Novel compact formula electric-bag complex dust collector
Technical field
The utility model relates to a kind of dust arrester that industrial smoke pollutes of controlling, and relates in particular to a kind of novel compact formula electric-bag complex dust collector of being made up of electric precipitation district airflow distribution device, electrostatic precipitator, cloth bag district airflow distribution device and rotary blowing bag-type dust collector etc.
Background technology
In commercial production, in thermal power generation, manufacture of cement, metallurgy industry, usually can produce the gas that contains a large amount of dust., before atmosphere, must purify these a large amount of gas rows that carry particulate matter through dust arrester.
Along with the raising of country to the industrial dust discharged standard, if will obtain higher efficiency of dust collection, can the deduster of different principle be combined by special mode, the particulate matter in the dust-contained airflow is united remove.Such as can be according to actual exhaust gas volumn and dust content; Use traditional electrostatic precipitator and the outside series connection of sack cleaner, compact series connection or intimate admixture; Coupling through to the cooperation-removal and the deashing process of particulate matter realizes high as far as possible efficiency of dust collection.
Unite with tandem at present that to remove be that the compound type dust remover design feature of know-why is with uses of connecting of traditional electrostatic precipitator and fixing row winding-up sack cleaner, this structure exists that the electrostatic precipitator reliability is weak, pulse valve quantity causes that the trouble point increases more, maintenance inconvenience and do not reach problems such as designing dust removing effects because the air-flow skewness brought.
Summary of the invention
The purpose of the utility model provides a kind of novel series-mode frame; Adopt cramped construction, electrostatic precipitator good reliability, bag-type dust collector pulse valve quantity is few, maintenance is convenient, air-flow is evenly distributed and efficiency of dust collection is high electricity bag composite dedusting device; Form by electric precipitation district airflow distribution device, electrostatic precipitator, cloth bag district airflow distribution device and rotary blowing bag-type dust collector, be disposed with electric precipitation district airflow distribution device, electrostatic precipitator, cloth bag district airflow distribution device and rotary blowing bag-type dust collector along airflow direction.
The utility model all is provided with airflow distribution device in electrostatic precipitation district and bag-type dust district, guarantees that different design and running requirements is satisfied in the air-flow distribution in electrostatic precipitator district and bag-type dust district, has guaranteed device subregion and whole efficiency of dust collection.
The rotary blowing bag-type dust collector of the utility model is made up of filter bag chamber, air-purifying chamber, heavy caliber pulse valve, swiveling jetting device, gas outlet and ash bucket etc.The rotary blowing bag-type dust collector is inner to distribute through rational flue gas flow field; Realized that filter bag bundle periphery flue gas low speed is to diffusion all around; Of the wearing and tearing of local jet have been avoided, the load situation of skewness of reentrainment of dust of also having avoided simultaneously causing from the air inlet of ash bucket top and air-flow filter bag that skewness causes to filter bag.
The rotary blowing bag-type dust collector of the utility model adopts bigbore pulse valve, and every pulse valve can be jetted and reached thousands of filter bags, has reduced the usage quantity of pulse valve, is merely 8 like the supporting pulse valve quantity of 300MW unit.Owing to adopted the pulse valve of lesser amt, judge the position of pulse valve trouble point easily, the trouble point is able to reduce.And conventional injection technology adopts small-bore pulse valve; Quantity is many; Be difficult for finding the particular location of down pulse valve,, can cause compressed air line to leak if because of 2~3 pulse valves break down or are not closed completely; The pressure of compressed air piping is reduced, cause the whole soot cleaning system cisco unity malfunction of dust arrester.
The rotary blowing bag-type dust collector of the utility model is because the turning arm of pulse dust cleaning is free to rotate; Make cloth bag, a bag cage conveniently take out and pack into; Need not as the row blowing bag-type dust remover, behind the dismounting pulse jet pipe, just can carry out more changing jobs of filter bag earlier.
Owing to adopt lower pulse dust cleaning pressure and good air-flow to distribute, the filtrate of rotary blowing bag-type dust collector is than the filtrate long service life of conventional at present long bag and low pulse winding-up sack cleaner.
Show through engineering measurement, adopt the electricity bag composite dedusting device of utility model, exhanst gas outlet dust content≤30mg/m 3(mark attitude), device body resistance≤1200Pa, device efficiency of dust collection>=99.99%.
Description of drawingsBelow in conjunction with accompanying drawing the utility model is done further to specify.
Fig. 1 is the main cross-sectional schematic of the utility model patent novel compact formula electric-bag complex dust collector.
Among the figure: 1. air inlet, 2. electric precipitation district airflow distribution device, 3. electrostatic precipitator, 4. cloth bag district airflow distribution device, 5. rotary blowing bag-type dust collector, 6. heavy caliber pulse valve, 7. swiveling jetting device, 8. air-purifying chamber, 9. filter bag chamber, 10, ash bucket, 11. gas outlets.
The specific embodimentIn Fig. 1, be disposed with air inlet (1), electric precipitation district airflow distribution device (2), electrostatic precipitator (3), cloth bag district airflow distribution device (4) and rotary blowing bag-type dust collector (5) along airflow direction.The rotary blowing bag-type dust collector is made up of filter bag chamber (9), air-purifying chamber (8), heavy caliber pulse valve (6), swiveling jetting device (7), gas outlet (11) and ash bucket (10) etc.
When a kind of novel compact formula electric-bag complex dust collector is in duty; Ash-laden gas is through air inlet (1); Airflow distribution device (2) is uniformly distributed with and laggardly goes into electrostatic precipitator (3) and carry out preparatory dedusting through the electric precipitation district; Most of dust granules in the flue gas can be caught by electrostatic precipitator (3); Remain about fine dust of about 25% through after the charged effect of electric field, do not caught through cloth bag district airflow distribution device (4), after reasonably flue gas flow field distributes, get in the rotary blowing bag-type dust collector (5) by electric field.The flue gas that contains fine dust is attached to the filter bag surface through filter bag chamber (9) after filter bag filters, through the deashing effect of heavy caliber pulse valve (6) and swiveling jetting device (7), dust releasing to ash bucket (10) is discharged.Clean flue gas enters atmosphere through air-purifying chamber (8) and gas outlet (11).
