Abstract
The utility model relates to a dust removing device which is suitable for high-temperature gases which have great power amount, high water content and corrosion. The utility model discloses an improved bag-type dust remover which takes a filter cloth as a filter bag, and the filter cloth is high temperature resistant and corrosion resistant. The utility model has the advantages of high dust removing effect, low investment, low operating cost, etc., and can be used for the dust removing of various industrial off-gases which have great power amount, high water content and corrosion.
Description
The utility model relates to a kind of industrial dedusting device, and it is big to be specially adapted to Dust Capacity, the high and mordant gas cleaning at high temperature of water content.
Contain more dust in a lot of industrial tail gas, resemble ardealite oven dry tail gas and come to this, contain the less acidic materials such as gypsum dust, steam and fluoride of a large amount of particle diameters.For impure more tail gas, use cyclone dust collectors usually, electric cleaner and washing come dedusting, but dust is tiny, and separating effect is poor more, and the electric precipitation investment is bigger, and water washing dedust also needs dust-laden sewage is handled.
The purpose of this utility model is the shortcoming for fear of above-mentioned deduster, and providing a kind of can carry out dedusting effectively, separative efficiency height, the lower dust arrester of investment again.
The technical solution of the utility model is such:
It is more to adopt a kind of improved sack cleaner to be used for moisture, the tails dedusting that dust size is little, sack cleaner comprises parts such as control valve, playpipe and filter bag like this, wherein filter bag is made by corrosion resistant terylene filter cloth, and is corresponding one by one through spray-hole and filter bag with the playpipe that the compressed air bag links to each other.
Said filter bag carries out pulse jetting deashing after certain filter cycle.Pressure-air by pulse valve control sprays at a high speed from spray-hole through playpipe from the compressed air bag, enters filter bag, will purge attached to the dust on the filter bag outer surface.In order to improve efficiency of dust collection and quality, cyclone dust collectors on can before sack cleaner, connecting, the air inlet of sack cleaner links to each other with pipeline with the cyclone dust collectors exhaust outlet.
Seldom amount was big in that dust is little in the past, and use sack cleaner during the strong gas medium dedusting of corrosivity, mainly be because filter bag is not corrosion-resistant, and the utility model is because the filter bag that has adopted corrosion-resistant terylene filter cloth to make, the length that just can avoid the shortcoming of prior art sack cleaner and raise it is mended the weak point of electricity, water and cyclone dust removal.Dust when the filter cloth, owing to effects such as adhesion, screening, diffusion and static are captured, use the action of the utility model operation deashing continuously, the filter bag pressure loss is stable, handles large-mindedly, and the inside nothing moves parts, simple in structure, the filter cloth life-span is long.The moisture content, temperature that the utility model is used to contain the small dust of a large amount of gypsum and 0-25% is more than 250 ℃ and the dedusting of the higher gypsum oven dry tail gas of content of fluoride, can remove grit greater than 0.1um, efficiency of dust collection is more than 99.5%, and investment and operating cost are also lower.
Introduce embodiment of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing is pocket type precipitator structure (section) schematic diagram, among the figure, and 1, exhaust outlet, 2, upper box body, 3, playpipe, 4, Venturi tube, 5, the compressed air bag, 6, control valve, 7, pulse valve, 8, air inlet, 9, filter bag, 10, the middle part casing, 11, ash bucket, 12, ash-valve.
Embodiment; Dedusting gas: ardealite drying and dewatering tail gas (280 ℃ of temperature, water content 27%, fluoride).Tail gas enters the middle part casing 10 that some filter bags 9 are housed by air inlet 8, and dust been separated in the filter bag outer surface.Purified gas enters upper box body 2 through Venturi tube 4, is discharged by exhaust outlet 1.Through after certain filter cycle, carry out pulse jetting deashing.Row's playpipe 3 all is equipped with on row's filter bag top.Link to each other with compressed air gas bag 5 through pulse valve 7; Spray-hole on the playpipe 3 is corresponding with every filter bag 9.Regularly send pulse signal by controller, each pulse valve 7 order is opened by control valve 6.At this moment, the playpipe 3 that links to each other with this pulse valve 7 communicates with gas bag 5, pressure-air sprays from spray-hole with flank speed, around high velocity air, form one and enter filter bag 9 through Venturi tube 4 together, filter bag is sharply expanded than big 5-7 times induced draft of winding-up air-flow, cause impact shock, produce the moment back draught simultaneously, will purge, fall into ash bucket 11 and discharge through ash-valve 12 attached to the dust on filter bag 9 outer surfaces.Each arranges filter bag deashing in turn successively.The present embodiment efficiency of dust collection is 99.5%.
Claims (3)
1, a kind of sack cleaner comprises control valve, and parts such as playpipe and filter bag is characterized in that the playpipe that links to each other with the compressed air bag is corresponding one by one with the filter bag of being made by corrosion-resistant terylene filter cloth through spray-hole.
2, sack cleaner as claimed in claim 1 is characterized in that said filter bag is by the pressure-air jetting deashing that sprays at a high speed from spray-hole through playpipe from the compressed air bag.
3, sack cleaner as claimed in claim 1 is characterized in that said air inlet is connected with pipeline with the exhaust outlet of cyclone dust collectors.
