Abstract
The utility model provides a compound type dust collector, solving the problems that the conventional dust collector can hardly meet the requirements of the national standards or is high in cost, short in service life and can not effectively solve the secondary pollution. The compound type dust collector comprises a box body, wherein the front part of the box body is provided with a fume inlet horn; an electric dust collector and a separated chamber positioning low-pressure back-blowing bag-type dust collector are respectively arranged at the front and rear sides inside the box body; and an air flow guide plate which is fixed with the inner wall of the box body and is provided with a plurality of through holes is arranged between the electric dust collector and the separated chamber positioning low-pressure back-blowing bag-type dust collector. The compound type dust collector is reasonable and reliable in structural design; the requirement of 30mg/Nm<3> of the new national standard is met, and the problems of large one-time investment and high later maintenance expense are overcome; the compound type dust collector is particularly applicable for the transformation of the conventional unqualified electric dust collectors; the pressure for dust cleaning by using a cloth bag is small; the damage on a filtering bag is small; the filtering bag is long in service life; furthermore external equipment are few; the electricity consumption is reduced; and the problems that the conventional dust collector can hardly meet the requirements of the national standards or is high in cost, short in service life and can not solve the secondary pollution effectively are overcome.
Description
Technical field
The utility model relates to fume dust remover, is specially a kind of composite duster.
Background technology
At present, at the industrial smoke cleaner---in the application of electric cleaner or sack cleaner, facing some problems can not effectively solve.Electric cleaner reaches new national standard≤30mg/Nm in actual motion
3Requirement difficulty relatively, if the ature of coal higher than resistance, that sulfur-bearing is low, ash content is high just is difficult to realize more, reach requirement, can only increase specification, strengthen investment, increase floor space.Though sack cleaner is less demanding to coal, be prone to reach≤30mg/Nm
3Emission request, but its one-time investment is big, life-span of the filter bag is short, replacing cloth bag expense once was high in 2-3 years, and the secondary pollution of waste and old cloth bag can not effectively solve.
Summary of the invention
Existing deduster is difficult to satisfy the problem that GB requires or cost is high, the life-span is short and secondary pollution can not effectively solve to the utility model in order to solve, and a kind of composite duster is provided.
The utility model is to adopt following technical scheme to realize: composite duster; Comprise that the front portion has the casing of smoke inlet loudspeaker; Forward and backward both sides in the casing are respectively arranged with electric cleaner and locellus location low pressure blowback sack cleaner, are provided with the gas-flow deflector of fixing and have some through holes with cabinet wall between electric cleaner and the locellus location low pressure blowback sack cleaner.Electric cleaner and locellus location low pressure blowback sack cleaner are prior art.
The rapping of electric cleaner adopts mechanical side to beat technology, and it is big to have rapping power, and transmission effect is good, easy-to-clean ash, and defective is few, characteristics such as easy-maintaining.According to different project situation, 1 or 2 electric fields and different electric field length can be set, the dust of 70%-80% is collected by electric cleaner and deashing falls into ash bucket, alleviates the load that gathers dust in cloth bag district, rear portion greatly.
Low pressure blowback sack cleaner in locellus location adopts the theoretical and minute-pressure ash-clearing technology of exclusive static deashing, has not only realized static filtering, and has realized static deashing; The about 3kPa of deashing pressure simultaneously is far smaller than the deashing pressure of the about 85k～300kPa of pulse dust collector, and the reduction of deashing pressure has reduced the infringement of deashing force to filter bag, thereby can prolong life of bag filter greatly; Secondly, complicated air machineries such as air compressor, air accumulator, pulse valve have been saved; Once more; Purify the back flue gas as the deashing source of the gas, its oxygen content is identical with the inner ash-laden gas oxygen content of deduster, and temperature is basically identical also; Thereby the filter bag oxidation that has caused when having avoided adopting compressed air and the problem of temperature difference dewfall as the deashing source of the gas, the service life of further having guaranteed filter bag; In addition, the high density bag cage that adopts the higher longitude and latitude steel wire of density to process has alleviated the weight of bag cage when guaranteeing bag cage self rigidity, intensity, reduced the infringement of bag cage deadweight to filter bag.
Between electricity district, bag district, gas-flow deflector is set, even with the smoke distribution that guarantees each unit, low pressure blowback sack cleaner bag district, entering locellus location, minimizing is to the erosive wear of cloth bag.
The utility model reasonable in design is reliable, has both reached new national standard 30mg/Nm
3Requirement, overcome the maintenance cost high problem that one-time investment reaches the later stage greatly again; The anterior electric cleaner that adopts of casing, easy-to-clean ash, maintenance, optimum is collected the dust of big or larger particles; Locellus location low pressure blowback sack cleaner is adopted at the casing rear portion, because the dedusting of anterior electric cleaner, back flour bag district dust concentration reduces, and therefore can suitably reduce cloth bag quantity, and prolongs cleaning cycle, thereby prolongs the cloth bag life-span, reduces cost; Simultaneously deashing pressure is low, little to the infringement of filter bag, life-span of the filter bag is long, and external device is few, power consumption is economized, the problem that overcome that existing deduster difficultly satisfies that GB requires or cost is high, life-span weak point and secondary pollution can not solve effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-smoke inlet loudspeaker, 2-casing, 3-electric cleaner, 4-locellus location low pressure blowback sack cleaner, 5-gas-flow deflector.
The specific embodiment
Composite duster; Comprise that the front portion has the casing 2 of smoke inlet loudspeaker 1; Forward and backward both sides in the casing 2 are respectively arranged with electric cleaner 3 and locellus location low pressure blowback sack cleaner 4, are provided with the gas-flow deflector 5 of fixing and have some through holes with casing 2 inwalls between electric cleaner 3 and the locellus location low pressure blowback sack cleaner 4.In the practical implementation process, have some through holes by air-flow distribution requirement on the gas-flow deflector 5.
