Description
Technical field
The present invention relates to deduster technical field, especially one is widely used between welding and cutting car, the high negative pressure type deduster of the fine metal particles that process suspension is harmful in atmosphere.
Background technology
Filter drum type precipitator just occurs in Japan and more American-European countries as far back as 20 century 70s, there is volume little, efficiency is high, reduced investment, the advantages such as easy care, but because its place capacity is little, difficulty is combined into Wind Volume equipment, and filtration velocity is on the low side, and range of application is narrow, only in the sector application such as grain, welding, so fail large-scale popularization for many years.In recent years, along with new technology, new material constantly develop, with Japan, the company of the U.S. is representative, the structure of deduster and filtrate are improved, make filter cartridge dust remover be widely used in the industrial circles such as cement, iron and steel, electric power, food, metallurgy, chemical industry, whole volume increases several times, becomes filter area >2000m
2large-scale deduster, be solve traditional deduster to ultrafine dust collect difficult, filtration velocity is high, ash-removal effect is poor, filter bag run-down, preferred plan that operating cost is high easy to wear, compare with various pocket type existing on market, electrostatic precipitator have that effective filtration area is large, pressure reduction is low, the feature such as low emission, volume are little, long service life, become the new direction of industrial dust collector development.Produce when welding and cut the harmful fine metal particles that suspends in atmosphere, traditional deduster complex structure, dust removing effects is bad.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides a kind of structure simple, the deduster of good dedusting effect.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high negative pressure type deduster, comprise dust-removing box, dust-removing box upper surface is provided with Sound Attenuator, Sound Attenuator surface is provided with gas outlet, be provided with dividing plate in described dust-removing box, dust-removing box inner chamber is separated into toilet and two, filter chamber locellus by dividing plate, and toilet communicates with Sound Attenuator, be provided with vavuum pump in exit, toilet, toilet's sidewall is provided with control cabinet and pulse ash remover; Dividing plate in described filter chamber is horizontally installed with filter stand, and the outer sheathed filter bag of filter stand forms filter, and filter chamber's sidewall offers air inlet, is connected with the ash bucket of taper bottom filter chamber, and hopper bottom is provided with the drawer collecting dust.Filter stand and filter bag all adopt fire-retardant material to make.
Further, described pulse ash remover comprises air accumulator, two injection tubes that air accumulator two ends are provided with magnetic valve and correspond, and magnetic valve is electrically connected with control cabinet.
Further, described vavuum pump is connected with motor, and electric machine built-in is in Sound Attenuator.
Further, bottom described dust-removing box, four angles are provided with dismountable leg.
Further, described filter chamber's sidewall offers access hole.
The invention has the beneficial effects as follows: structure of the present invention is simple, reasonable in design, for suspending, fine metal particles harmful in atmosphere filters, and has overall volume little, efficiency of dust collection is high, operation controls easy, long service life and the advantage such as intermittent deashing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Wherein: 1. dust-removing box, 2. Sound Attenuator, 3. dividing plate, 4. air inlet, 5. gas outlet, 6. vavuum pump, 7. motor, 8. filter stand, 9. filter bag, 10. ash bucket, 11. drawers, 12. control cabinets, 13. air accumulators, 14. magnetic valves, 15. legs.
Detailed description of the invention
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, and therefore it only shows the formation relevant with the present invention.
High negative pressure type deduster as shown in Figure 1, comprise dust-removing box 1, dust-removing box 1 upper surface is provided with Sound Attenuator 2, Sound Attenuator 2 surface is provided with gas outlet 5, be provided with dividing plate 3 in dust-removing box 1, dust-removing box 1 inner chamber is separated into toilet and two, filter chamber locellus by dividing plate 3, and toilet communicates with Sound Attenuator 2, be provided with vavuum pump 6 in exit, toilet, toilet's sidewall is provided with control cabinet 12 and pulse ash remover; Dividing plate 3 in filter chamber is horizontally installed with filter stand 8, and the outer sheathed filter bag 9 of filter stand 8 forms filter, and filter chamber's sidewall offers air inlet 4, is connected with the ash bucket 10 of taper bottom filter chamber, is provided with the drawer 11 collecting dust bottom ash bucket 10.
Pulse ash remover comprises air accumulator 13, two injection tubes that air accumulator 13 two ends are provided with magnetic valve 14 and correspond, and magnetic valve 14 is electrically connected with control cabinet 12; Vavuum pump 6 is connected with motor 7, and motor 7 is built in Sound Attenuator 2; Bottom dust-removing box 1, four angles are provided with dismountable leg 15; Filter chamber's sidewall offers access hole.
Filtration condition: open motor 7 and drive vavuum pump 6 to work, dusty gas is after air inlet 4 enters filter chamber, and due to the sudden enlargement of air-flow section, in air-flow, a part of big particle is moving and is being deposited in ash bucket 10 under inertia force effect; After the grit that fine size, density are little enters filter chamber, by combined effects such as Blang's diffusion and sievings, make dust deposit at filter bag 9 on the surface, purified gas enters toilet and discharges by through gas outlet 5.
Deashing state: pulse ash remover is timing means, after a period of operation, the air of air compressor enters air accumulator 13, magnetic valve 14 is opened, compressed air sprays instantaneously through injection tube, make filter bag 9 dilatancy produce vibration, and under the effect of washing away at inverted draft, the dust be attached on filter bag 9 outer surface is stripped and fall into ash bucket 10.After deashing, magnetic valve 14 cuts out, and filtration condition recovers again in filter chamber.The dust come off is fallen in ash bucket 10 and is collected into drawer 11.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
