Abstract

The utility model relates to a stair-type electrical bag dust remover, which comprises an electrical dust remover and a cloth bag dust removing device; the device includes two sets of components and is isolated by a partition wall in the middle; an electric valve is arranged at the front end of an inlet flue box in the electrical dust removing device, and a bypass flue duct is arranged at the upper part of an electrical dust removal area; a cloth bag purifying chamber in the cloth bag dust removing device adopts the stair-type arrangement, and an outlet flue duct is arranged at the upper part respectively. The utility model has the advantages of compact structure, low cost, high dust removal efficiency, safe and stable operation, on-line maintenance and the like.

Description

A kind of staged electricity bag dust collector
One, technical field
The utility model relates to a kind of dust arrester, relates in particular to a kind of staged electricity bag dust collector.
Two, background technology
Current, the assembled electric bag dust collector design feature on the market is: be provided with in the housing of prime by negative electrode, anode, rapping apparatus, in the level bag-type dust removal system of back the filter bag device arranged.Its each zoning design of filter bag device is in conplane air-purifying chamber.After the flue gas that contains dust enters deduster, prime electric precipitation negative electrode is connected negative high voltage power source, thereby plus earth produces electric field in electric cleaner, and make dust charged, most of charged dust is driven to anodic-cathodic, the residue dust arrives level bag-type dust district, back, is captured by filter bag, reaches dust collection effect.There are some defectives in this structure: can't realize on-bne repair, and when system's flue-gas temperature surpasses cloth bag safe handling temperature, because there is not bypath system, can't effectively protect the safety of filter bag; Because its each zoning design of filter bag device at grade, when prime electric field height surpassed 10 meters, there were problems such as wasting space, increase cost in level cloth bag district, back.
Three, summary of the invention
The purpose of this utility model provides a kind of compact conformation, cost is low, efficiency of dust collection is high, security of operation is stable, the deduster of energy on-bne repair.
For achieving the above object, the technical solution adopted in the utility model is:
It comprises electric dust collector and bag-type dust collector composition, and this device is formed has two covers, centre to have partition wall to isolate; The import smokebox front is provided with an electrically operated valve in the described electric dust collector, and top, electric precipitation district is provided with the bypass flue; The cloth bag air-purifying chamber is that staged is arranged in the described bag-type dust collector, and top is respectively equipped with exhaust pass.
Compared with prior art, the utlity model has following effect:
Because but the utility model is made up of the electric dust collector and the bag-type dust collector of two cover independent operatings, when wherein a cover system device breaks down, can close the electrically operated valve of its import smokebox front, flue gas be guided to another set of system handle, realize on-bne repair; Be provided with the bypass flue, when system's flue-gas temperature surpasses cloth bag safe handling temperature, can effectively protect filter bag, guarantee that security of operation is stable; The cloth bag air-purifying chamber is that staged is arranged, and can effectively utilize shell space, reduces material consumption and cost.
Four, description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the staged electricity bag dust collector structural representation front view that the utility model proposes.
Fig. 2 is the staged electricity bag dust collector structural representation vertical view that the utility model proposes.
Figure acceptance of the bid keep the score not Biao Shi:
1. ash bucket 2. housings 3. electrically operated valves 4. import smoke boxes
5. electric precipitation district 6. bypass flues 7. exhaust pass 8. bag-type dust air-purifying chambers
9. bag-type dust collector 10. partition walls 11. high voltage power supply devices
Arrow is represented the flow of flue gas direction among Fig. 1, Fig. 2.
Five, the specific embodiment
As can be seen from Figure 1, near import smoke box 4 front ends an electrically operated valve 3 is set, housing 2 belows are provided with ash bucket 1, be disposed with electric precipitation district 5 and bypass flue 6, bag-type dust collector 9 and bag-type dust air-purifying chamber 8 and exhaust pass 7 along airflow direction in the housing 2, bag-type dust air-purifying chamber 8 is lined up staged successively.
As can be seen from Figure 2, but the utility model by two the cover independent operatings electric dust collector and bag-type dust collectors form.
When a kind of deduster is in running order, cathod system in the electric precipitation district 5 connects the negative high voltage electric supply installation, partly form a high voltage electric field with anode system prime in housing 2 of ground connection, when flue dust enters electric field from import smoke box 4 after the airflow uniform distribution device current-sharing, dust granules in high voltage electric field by charged, and under the effect of electric field force, move to heteropole, be deposited on negative electrode frame or the positive plate, when dust that electrode surface captured reaches certain thickness, apply the effect of rapping power by rapping apparatus respectively, the dust layer of heavy collection on electrode dropped in the ash bucket 1.Flue gas after the preliminary purification of prime electric field enters bag-type dust collector 9 and makes further purified treatment, fine solid particle rests on the surface of filter bag after filter bag filters, when the dust that is captured when the filter bag surface reaches certain thickness, respectively by the deashing device effect, make to be captured in the lip-deep dust layer of filter bag and to drop to ash bucket 1.Clean flue gas is discharged from exhaust pass 7, finishes the clarifying smoke process.
Because but the utility model is made up of the electric dust collector and the bag-type dust collector of two cover independent operatings, the middle partition wall 10 that adopts is isolated fully.When a cover system prime electric field wherein breaks down or a back level filter bag when problem such as breakage occurring, the electrically operated valve 3 of fault chamber import smoke box 4 fronts can be closed, and flue gas is guided to another chamber, is handled by another set of system, thereby realizes on-bne repair.When system's flue-gas temperature surpasses cloth bag safe handling temperature, can open bypass flue 6, make flue gas without the filter bag district, effectively protect filter bag, guarantee that security of operation is stable.
