The specific embodiment
Below in conjunction with accompanying drawing, the utility model is illustrated:
A kind of novel deduster, comprise filter bed layer 8, expansion chamber 6, filter bed layer 8 is provided with filtrate, described filter bed layer 8 top one side are provided with pulse tube 9, pulse tube 9 has the gas outlet 10 towards stratum granulosum, the bore of gas outlet 10 is 3mm～7mm, and pulse tube 9 is communicated with feeder via tube connector 13, and tube connector 13 is provided with the motor-driven valve 11 that control impuls pipe 9 opens and closes.Feeder is selected air pump.Or compressed air cylinder.
The filter bed layer 8 that is parallel to that gas outlet 10 is a row arranges, and purges efficiency higher.Gas outlet 10 is suitable apart from the height of filtrate face, too low not all right, and too low meeting blows afloat filtrate.
Better effects if be that filter bed layer 8 top arrange preferably three of at least one scraper plate 1(again, be arranged in parallel), 1 of described scraper plate is vertical with filtrate upper surface, the long limit of scraper plate 1 is parallel with the limit 12 that filter bed layer 8 contacts with expansion chamber 6, described scraper plate 1 is fixed on mobile device, scraper plate 1 bottom is pressed close to filter material surface and is moved by the mobile device band action cycle, and shiftable haulage line is the direction vertical with limit 12.
This mobile device can be chain drive, the chain 2 that comprises gear 5, is connected with gear, described scraper plate 1 two ends are fixed on two relative chains 2, gear 5 is supported by hold-down support 3, wherein two relative geared sleeves are located on power transmission shaft 4, power transmission shaft 4 connects the output shaft of reducing motor 7, and two other relative gear 5 can arrange connecting axle, also can not establish connecting axle; This mobile device can also be belt transmission, mobile device comprises belt pulley, coordinates belt with gear, described scraper plate 1 two ends are fixed on two relative belts, belt pulley is supported by hold-down support 3, wherein two relative belt pulleys are set on power transmission shaft 4, power transmission shaft 4 connects the output shaft of reducing motor 7, and two other relative belt pulley can arrange connecting axle equally, also can not establish connecting axle.When dedusting environment is normal temperature, belt can be selected plain edition number, must select the belt of heat-resisting material, as Teflon material when dedusting environment temperature is high.
After blowback EO, by 4～10 seconds, feeder air feed, magnetic valve 11 is opened pulse tube 9 by gas outlet 10 air-out, the dust that blowback is risen blows to expansion chamber 6 tops, make ash be deposited to ash bucket, rather than fall again on stratum granulosum, improved the effect of blowback, the scraper plate 1 of setting up motion back and forth, the ash that drops on stratum granulosum is scraped to expansion chamber 6, reduce dust stratification, the pressure loss is just little, can be at lasting filtration dust of long period, frequent deashing, make it to adapt to the technological operation of the large soot amount such as metallurgical furnace cellar for storing things, the motion frequency of scraper plate 1 is according to the size adjustment of processed soot amount, the large cycle back and forth of ash amount is just short.
Deduster shown in Fig. 4, Fig. 5 has eight layers, and airduct has two, and negative-pressure air duct 16,14, two pipes of reverse-blow pipe can be replaced mutually, in actual production, by position and the blower fan air-out direction of blower fan, are determined.Back blowing machine during deduster work (back blowing machine air outlet connects reverse-blow pipe) and negative-pressure air fan (negative-pressure air fan connection negative-pressure air duct) are in opening, pulse tube 9 is 4～10 seconds motor-driven valve 11(magnetic valves after blowback finishes) unlatching air-out purging, make it to fall into ash bucket, prevent that the dust blowing afloat from falling again on filtrate, do not affect the filtration of other layers, layer deashing or minute odevity layer that successively deashing or selection ash amount are large are cleared up.Add after upper scraping plate 1, scraper plate 1 and pulse tube 9 coordinate with original dust removal operation, when the one deck in deduster carries out blowback, scraper plate 1 stops mobile, back-flushing valve 15 is opened, and negative pressure air-valve 17 cuts out, and implements blowback operation, after blowback finishes, back-flushing valve 15 is closed, and negative pressure air-valve 17 is opened, and recovers to filter, pulse tube 9 air-out in approximately 4～10 seconds after blowback finishes purges, and makes ash fall into ash bucket.
If the utility model is combined with PLC control device, the travel frequency of scraper plate, initial stopping can being freely set, pulse tube purge time is adjustable, and layering deashing, realizes automatic operating.This deduster can replace fiber bag precipitator, realize large exhaust gas volumn, high temperature, acid, alkali environment, as in the situations such as nickel aluminum bronze iron smelting the continuous dedusting of large ash amount, can reach or be better than the dust removing effects of fiber bag precipitator, meet environmental requirement, alleviate Dust Capacity in atmosphere, reduce the generation of the environmental pollutions such as haze, favourable people's health.Middle-size and small-size workshop fiber bag precipitator 1 year need to change 1000 left and right cloth bag, a high temperature acid and alkali-resistance cloth bag is in 1000 yuan, 1 year cloth bag cost will more than 100 ten thousand, between large car, just need to change more cloth bag, and be to guarantee when cloth bag is changed in continuous dedusting to enable another tablecloth sack cleaner, minimum two tablecloth sack cleaners, and this deduster is sandwich construction, the dust that one deck deashing does not affect other layer filters.Owing to adopt connecting, blow the mode that band is scraped, can not produce the blocked up workman of needs of grieshoch and climb and open cleaning door and go to harrow grey situation, safe and reliable, saved manpower, maintenance cost is low.
