Description
Technical field
The utility model relates to a kind of deduster, is specifically related to a kind of sack cleaner.
Background technology
At present, domestic existing rotary counter-blowing sack cleaner, great majority are applicable to the normal temperature dedusting, udst separation for high temperature flue gases such as fuel boiler, kiln, spray drying towers, be easy to stick with paste the phenomenon of bag, coking, corrosion filter bag, and exist filter efficiency low, not easy-to-clean ash, high-temperature flue gas can not desulfurization etc. defective, therefore be subjected to very big restriction in the use.
Summary of the invention
The purpose of this utility model 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.
For achieving the above object, the utility model is by the following technical solutions: sack cleaner, comprise: the deduster housing, filter bag, back blowing machine, air-introduced machine, blast pipe, discharge pipe etc., the deduster housing fixes by support and ground, filter bag is in the deduster housing, blast pipe is positioned at the middle part of deduster housing, air-introduced machine, discharge pipe is 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, and the adder funnel is housed on the blast pipe, quenching system is provided with the planet dispenser between blast pipe and adder funnel, dust hopper is positioned at the deduster lower housing portion, and twin-stage turnover panel discharger is positioned at the bottom of dust hopper.
The beneficial effects of the utility model are, have simple in structure, applied widely, efficiency of dust collection height, and advantages such as pair high-temperature flue gas desulfurization are arranged.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, quenching system; 2, blast pipe; 3, planet dispenser; 4, adder funnel; 5, deduster housing; 6, filter bag; 7, back blowing machine; 8, discharge pipe; 9, air-introduced machine; 10, dust hopper; 11, twin-stage turnover panel discharger; 12, support
Specific implementation method
Among the embodiment shown in Figure 1, a kind of sack cleaner, comprise: deduster housing 5, filter bag 6, back blowing machine 7, air-introduced machine 9, blast pipe 2, discharge pipe 8 etc., deduster housing 5 fixes by support 12 and ground, filter bag 6 is in deduster housing 5, blast pipe 2 is positioned at the middle 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, dust hopper 10 is positioned at deduster housing 5 bottoms, and twin-stage turnover panel discharger 11 is positioned at the bottom of dust hopper 10.Operation principle of the present utility model is, flue gas enters deduster housing 5 by blast 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 blast pipe 2 and flue gas by some cycles, the filter aid composition is that silicate material (has 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 is helping filtering layer to adsorb, 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 from sticking with paste bag, coking, and can reduce corrosion to filter bag 6, improve the service life of filter bag 6, dust falls into dust hopper 10 behind the deashing, by being positioned at twin-stage turnover panel discharger 11 emptyings of dust collecting opening 10 bottoms, 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.This use new structure is simple, and the scope of application is wide, the efficiency of dust collection height, and advantage such as pair high-temperature flue gas desulfurization is arranged, be the desirable substitute products of existing sack cleaner.
