The dust collection is small and adaptable in the coal mine, adopts a structure with spiral-flow dehydrator to improve the dust collecting efficiency and dehydrate efficiency to make the dust collecting efficiency up to 99 percent as the dehydrate efficiency is up to 95 percent, and effectively improves the working and sanitary conditions in the operation site.
Description
One, technical field
The utility model relates to a kind of wet-type rotational flow dust-cleaning equipment, be used under the coal mine and the serious operation place of industry dust hazard, ground, move and fixed point dirt source as down-hole tunneling working face, anchor spray working face, fully-mechanized mining working return airway and coal bunker, steel mill, coal washery etc.
Two, background technology
Research practice shows both at home and abroad, utilizes deduster for the main dust prevention of taking out the dirt purification techniques, can effectively reduce the dust concentration in various operations place under the coal mine.
For the efficiency of dust collection that improves deduster and the adaptability under coal mine, the external flourishing country of mining has carried out number of research projects to deduster, and has obtained comparatively desirable effect.As having adopted the high-efficiency low-resistance wet-type rotational flow dust-cleaning equipment at tunneling working face abroad, the dust concentration at development machine driver place is descended significantly, up to more than 99%, dewatering efficiency is up to more than 98% to the efficiency of dust collection of total dust for this deduster; The dust of the synthesis dust prevention measure control cutterhead that abroad external spraying and sack cleaner combine in tunneling working face adopts makes the respirable dust concentration that purifies driver place, back be reduced to 1mg/m
3, greatly improved the condition of work of tunneling working face.
At present, the cleaner of applying under the coal mine at home is KGC-I type, KGC-II type wet scrubber and GBC, KLM-60 type sack cleaner.But these dedusters are compared with external advanced deduster of mining country, also have sizable gap on performance, and wherein the efficiency of dust collection of KGC-I type, KGC-II type wet filter dust collecting technique device has only 95%, and it handles air quantity scope (150m less than normal
3/ min), dewatering efficiency not high (about 75%), fan efficiency low (about 50%), particularly the efficiency of dust collection to respirable dust only is 80%-85%, uses the dust concentration of back working face still can not reach effective requirement that improves operation place labour health condition.Especially dehydration problem is unresolved so far, though the dust concentration of deduster outlet reduces, but the corrugated plating evaporation dehydrating effect that is adopted is very limited, add that resistance is big, the distinguished and admirable moisture height that deduster is discharged, working face water smoke fills the air, and healthy very unfavorable to the workman has been difficult to adapt at present the needs of tunneling working face depositing dust and labour health under the coal mine; GBC and KLM-60 type sack cleaner, because the deduster volume is big, quality is heavier, move inconvenient and need switch valve and compressed air etc., and cost is higher, applicability is not strong.
External UO-600 cyclone dust, efficiency of dust collection height (reaching 99%), its dehydrator is further dedusting in dehydration.This deduster is suitable at basal area 14m
3About machine pick face use, but exist the installation site to limit and move problems such as difficulty and price are expensive in the application of China's coal-mine down-hole tunneling working face because of grow (about 10m).Though domestic KGC-II type wet filter dust collecting technique device efficiency of dust collection is higher and volume is little, costs and poor dehydration results.
In order to improve the applicability of deduster in dust removing down-hole of coal mine and dewatering efficiency and use, when introducing the external UO-600 cyclone dust technology of digestion, also adopt the advantage of the KGC-II type wet filter dust collecting technique device of China, in conjunction with working condition situation under the coal mine, the development wet-type rotational flow dust-cleaning equipment, can collect dedusting, dewater is one, volume is little, is that the strong cleaner of applicability is used in a kind of China's coal-mine down-hole that is adapted at.This deduster adopts the centrifugal cyclone dehydration theoretical, reduces resistance, improves dehydration rate; Take all factors into consideration supporting blower fan and dehydration part structure, make it compact, practical.
Three, summary of the invention
The purpose of this utility model is little in order to improve dedusting and dewatering efficiency and the volume of deduster under coal mine, is adapted at using under the coal mine, and applicability is strong, and the wet-type rotational flow dust-cleaning equipment of development is a kind of comparatively ideal cleaner.
At present, the cleaner of applying under the coal mine at home is KGC-I type, KGC-II type wet scrubber and GBC and KLM-60 type sack cleaner.But these dedusters are compared with external advanced deduster of mining country, also have sizable gap on performance, though wherein the efficiency of dust collection of KGC-I type, KGC-II type wet filter dust collecting technique device has 95%, it handles air quantity scope (150m less than normal
3/ min), dewatering efficiency not high (about 75%), fan efficiency low (about 50%), the particularly efficiency of dust collection to respirable dust only be 80%-85%, use the dust concentration of back working face still can not reach effective requirement that improves operation place labour health condition, especially dehydration problem is unresolved so far, because of the corrugated plating evaporation dehydrating effect that its adopts very limited.GBC and KLM-60 type sack cleaner, because the sack cleaner volume is big, quality is heavier, move inconvenient and need switch valve and compressed air etc., and the cost height, applicability is not strong.External UO-600 cyclone dust, efficiency of dust collection are up to 99%, and its dehydrator is further dedusting in dehydration.But this deduster is suitable at basal area 14m
2About machine pick face use, but because of grow (about 10m), exist the installation site to limit and move problems such as difficulty and price are expensive in the application of China's coal-mine machine pick face.Though domestic KGC-II type wet filter dust collecting technique device efficiency of dust collection is higher and volume is little, costs and poor dehydration results.When introducing the external UO-600 cyclone dust technology of digestion, also adopt the advantage of the KGC-II type wet filter dust collecting technique device of China,, provide a kind of wet-type rotational flow dust-cleaning equipment in conjunction with working condition situation under the coal mine.
