Abstract

The utility model discloses a dust collector with a bag type, comprising a casing of the dust collector, a filter bag, a back blower, a draught fan, an air inlet pipe and an air outlet pipe, wherein, the air inlet pipe is provided with a hopper of an adjunction device and a cold wind system; a planet feeder is arranged between the air inlet pipe and the adjunction device; a double-stage turning plate is arranged at the lower part of the casing of the dust collector. The utility model has the advantages of simple structure, wide application range and high dust removing effect, and can carry out flue desulfurization of flue gas with high temperature. The utility model is an ideal substitute of the existing dust collector of a bag type.

Description

Sack cleaner
The utility model relates to a kind of deduster, particularly a kind of sack cleaner.
At present, domestic existing rotary counter-blowing sack cleaner is applicable to the normal temperature dedusting to the greatest extent, for the udst separation of high temperature flue gases such as coal-burning boiler, kiln, spray drying tower, easily take place to stick with paste bag, coking, corrosion filter bag, and filter efficiency is low, not easy-to-clean ash, high-temperature flue gas can not desulfurization etc. defective.
The purpose of this utility model just is to overcome weak point of the prior art, provides a kind of simple in structure, wide accommodation, and the efficiency of dust collection height, and can be to the sack cleaner of high-temperature flue gas desulfurization.
The purpose of this utility model is to realize like this, it comprises: deduster housing, filter bag, back blowing machine, air-introduced machine, into and out of airduct, filter is contained in the deduster housing, blast pipe is positioned at the middle and lower part of deduster housing, air-introduced machine, discharge pipe are positioned at the top of deduster housing, back blowing machine is positioned at the top of deduster housing, air-introduced machine links to each other with discharge pipe, adder funnel, quenching system are housed on the blast pipe, be provided with the planet dispenser between blast pipe and adder funnel, twin-stage turnover panel discharger is positioned at the deduster lower part of frame.
Compared to existing technology, the utlity model has simple in structure, wide accommodation, efficiency of dust collection height, and can be to advantages such as high-temperature flue gas desulfurization.
Accompanying drawing and drawing explanation
Accompanying drawing is the utility model structural representation
Below in conjunction with drawings and Examples in detail the utility model is described in detail, it comprises: deduster housing 5, filter bag 6, back blowing machine 7, air-introduced machine 9, advance, discharge pipe 2,8, filter bag 6 is contained in the deduster housing 5, blast pipe 2 is positioned at the middle and lower part of deduster housing 5, air-introduced machine 9, discharge pipe 8 is positioned at the top of deduster housing 5, back blowing machine 7 is positioned at the top of deduster housing 5, air-introduced machine 9 links to each other with discharge pipe 8, adder funnel 4 is housed on the blast pipe 2, quenching system 1,4 in blast pipe 2 and adder funnel are provided with planet dispenser 3, and twin-stage turnover panel discharger 11 is positioned at the bottom of deduster housing 5.Operation principle of the present utility model is, flue gas enters deduster housing 5 by air inlet pipe 2, when deduster housing 5 internal resistances rise to 1200Pa, back blowing machine 7 carries out reverse gas cleaning, when deduster housing 5 internal resistances drop to 800Pa, stop blowback, filter aid in the adder funnel 4 is under the effect of planet dispenser 3 simultaneously, be mixed in the deduster housing 5 by airduct 2 and flue gas by some cycles, the filter aid composition is that silicate material is (by flyash, calcium oxide, talcum powder mixes by a certain percentage, granularity requirements is below 0.5mm), the addition of filter aid can arbitrarily be adjusted according to the content of smoke dust, the filter bag 6 surface formation that filter aid is adsorbed on behind the deashing help filtering layer, help filtering layer to form back planet dispenser 3 and stop to add filter aid, dust in the high-temperature flue gas adsorbs helping on the filtering layer, filter, part pernicious gas wherein is (as sulphur, acid, alkali etc.) also chemical reaction can take place with filter aid, efficiency of dust collection is improved, the filtering layer that helps that filter bag 6 surfaces form can effectively prevent to stick with paste bag, coking, and can reduce corrosion to filter bag 6, improve the service life of filter bag 6, dust falls as dust hopper 10 behind the deashing, discharge by the bottom twin-stage turnover panel discharger 11 that is positioned at deduster housing 5, flue gas after being purified is through being positioned at the top discharge pipe 8 of deduster housing 5, air-introduced machine 9 emptyings, when deduster continuous operation in high-temperature flue gas, temperature in the deduster housing 5 can constantly increase, will inevitably influence dust removing effects, and reduced the service life of filter bag 6, thereby the quenching system on the blast pipe 21 can be sent into cold wind by blast pipe 2 according to variation of temperature in the deduster housing 5 in trend deduster housing 5, so that the temperature in the deduster housing 5 keeps stable, to guarantee the service life of efficiency of dust collection and equipment.The utility model is simple in structure, wide accommodation, and the efficiency of dust collection height, and can be to the high-temperature flue gas desulfurization etc., be the desirable substitute products of existing sack cleaner.
