Abstract

A single-chamber electric bag composite dust remover comprises a filter chamber electric field area and a filter chamber filter bag area communicated therewith, the filter chamber filter bag area therein is provided with a plurality of filter bags, the gas outlet of the filter chamber filter bag area is communicated with a gas purification chamber, the lower ends of the filter chamber electric field area and the filter chamber filter bag area are respectively provided with an ash bucket, a ring beam and a tube nest are arranged between the gas purification chamber and the filter chamber filter bag area, a keel and the filter bags are fixed on the tube nest, and the gas purification chamber thereon is provided with a pulse blowing system. As the whole filter chamber adopts a single-chamber structure, dust-containing gas enters the filter chamber electric field area so as to pre-remove dust and pre-charge the dust-containing flue gas with a high concentration, the filter bags are arranged in the filter chamber filter bag area in groups, clean coal gas enters the gas purification chamber from the filter bags through the filtration of the filter bags and then horizontally flows out from the dust remover from the gas outlet, so as to improve dust collection performance, deduce system resistance, greatly reduce the dust removal load of the filter bag area and prolong the service life of the filter bags, without hazard caused by high specific resistance.

Description

A kind of single chamber electric-bag complex dust collector
Technical field
The utility model relates to a kind of electric-bag complex dust collector, is used for the single chamber electric-bag complex dust collector of big dust content gas cleaning in particularly a kind of environmental protection field.
Background technology
Up to now, the purification of China's coal fired thermal power plant and cement rotary kiln kiln tail flue dust, basically adopt electric precipitation, past is in order to save construction investment, efficiency of dust collection requires on the low side, lectotype selection is less than normal, along with national environmental standard requires to improve constantly, expense that pollutant emission is imposed and requirement are more and more higher, the concentration of emission of most of electric cleaners can not satisfy new environmental requirement, also is a new problem to effective capture of subparticle dust, and electric cleaner has been taked a lot of corrective measures from design, as increase electric field, change the utmost point and join or the like, but produce little effect.For this reason, electric cleaner is transformed into bag dust collector, slowly become a kind of developing direction.But new problem produces again thereupon.Shortcomings such as equipment volume is big, running resistance is high, maintaining is frequent become a big drawback of sack cleaner.At these problems, a kind of single chamber electric-bag complex dust collector arises at the historic moment, and promptly prime is gathered dust and is electric precipitation, and the back level is the filter bag dedusting.
In newly-built coal fired thermal power plant and cement rotary kiln kiln tail clarifying smoke scheme, as adopt conventional electric cleaner scheme,, can only increase specification of equipment, just increased investment unavoidably greatly for adapting to new environmental protection standard; As simple employing bag dust collector, load is big, resistance is big, life of bag filter is low, and frequent replacing filter bag is a unavoidable problem, thus adopt this electric-bag complex dust collector, more than both advantage just be able to complementation technically.
The deduster of this pattern is specially adapted to go into operation not up to standard, the electric cleaner transformation that the place is restricted, modification scheme keeps first electric field of former electric cleaner generally speaking, utilize back level space alteration to be the bag dedusting, not only investment cost is little, the transformation cycle short for this forms of modification, and technical performance is very superior.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provide a kind of efficiency of dust collection height, long service life, simple in structure, the operation maintenance is convenient, online independent deashing can be applicable to the single chamber electric-bag complex dust collector of big dust content gas cleaning.
For achieving the above object, the technical solution adopted in the utility model is: comprise filter chamber's electric field region that has the air inlet loudspeaker and the filter bag district, filter chamber that is connected with this filter chamber's electric field region, the filter chamber is provided with several filter bags in the filter bag district, the gas vent in filter bag district, filter chamber with the air-purifying chamber that exports loudspeaker that has be connected, the lower end in filter chamber's electric field region and filter chamber's filter bag district is respectively arranged with ash bucket, be provided with the collar tie beam and the card of buffer action between air-purifying chamber and filter chamber's filter bag district, the cage bone and the filter bag that are positioned at filter bag district, filter chamber are fixed on the card; The pulse jet system is set on air-purifying chamber.
Be equipped with on the sidewall of ash bucket of the present utility model and purge mouthful and broken arch mouthful, broken arch mouthful links to each other with Arch-Breaking Device by broken arch ball valve; Be provided with gas distributor in the air inlet loudspeaker; Filter chamber's electric field region is made up of positive plate that is connected with high-voltage rectifier power source and cathode line, and is respectively arranged with anode vibrated system and cathode rapping system on positive plate and cathode line; The pulse jet system comprises the interior winding-up pipe of the band drainage nozzles that is arranged on the card upper end, and the inlet of interior winding-up pipe is connected with gas bag by pulse valve, offers the injection hole that is connected with interior winding-up pipe on the sidewall of air-purifying chamber; Filter chamber's electric field region and bottom, filter chamber's filter bag district are equipped with manhole.
Because the whole filter chamber of the utility model adopts single cell structure, dusty gas enters filter chamber's electric field region from the air inlet loudspeaker, filter chamber's electric field region of compact conformation is realized the pre-dedusting of big concentration ash-laden gas and charged in advance, the filter bag grouping is arranged on filter bag district, filter chamber, filter by filter bag, clean coal gas rises up into air-purifying chamber in filter bag, level flows out deduster from the gas outlet.Because the pre-dedusting and the pre-charged effect of filter chamber's electric field region, enter the filter bag district after making on the grit band electric charge and the carrying capacity that reaches capacity, caught by the filtering surface of filter bag.Be deposited on the dust on filter bag surface, assemble electric charge and increase particle diameter and static repulsion force by the static aggegation, realize the non-dense set degree on filter bag surface, improved dust collection performance, reduced SR, do not have the harm that high specific resistance brings again, alleviated the dedusting burden in filter bag district significantly, prolonged the service life of filter bag.
