Abstract

Provided is a high-efficiency whirlwind dust collector by integrating gravity settlement and whirlwind dust collection. The dust collector comprises cyclones and a housing with an air inlet and an air outlet; an empty cavity in the housing is divided into a first grade gravity settling chamber and a second grade gravity settling chamber by an upper tube sheet of the cyclones, a lower tube sheet of the cyclones and a damping plate inside the housing, the air inlet is communicated with the first grade gravity settling chamber, and the air outlet and a dust outlet are communicated with the second grade gravity settling chamber; a plurality of inclined cyclones are distributed in the first grade gravity settling chamber in the device, the gravity settlement and the whirlwind dust collection are effectively integrated in the structure, therefore, in principle, the structure is that the gravity settlement, the whirlwind dust collection and the gravity settlement are in three-level series connection, and thus the dust collection efficiency is high; and because the single cyclone has a small size, the efficiency of the whirlwind dust collection is high, and the total efficiency of the whirlwind dust collection is improved. The structure has another advantage that the plurality of cyclones are in parallel connection and arranged in the same housing, and thus the processing air quantity can increase with the increase of the number of the cyclones. And the heat radiation area of the system is reduced, so that the heat radiation of the system is reduced.

Description

A kind ofly collect the efficient cyclone dust-precipitator that gravity gathers dust
Technical field
The present invention relates to a kind of dust collection device that utilizes gravity to gather dust, a kind ofly specifically collect the efficient cyclone dust-precipitator that gravity gathers dust.
Background technology
At present, deduster on the market has been the technology of comparative maturity, mainly contain that cyclone dust removal, gravitational dust collection, pocket type are gathered dust, electric precipitation etc., yet based on gravitational settling and also few in conjunction with the equipment of cyclone dust removal, and mostly device is all poor because of complex structure, dust collection effect, make that its result of use is relatively poor, the efficient cyclone dust-precipitator of therefore being badly in need of to provide a kind of good separating effect, collection gravity that energy consumption is low to gather dust.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of efficient cyclone dust-precipitator that gravity gathers dust that collects, this device is by the sub-upper face plate of whirlwind, the sub-lower face plate of whirlwind will rationally intercept into one-level gravity settling chamber and secondary gravity settling chamber with damping sheet in the dedusting housing, and be obliquely installed whirlwind to be distributed in the one-level gravitational settling indoor a plurality of, this structure efficient set gravitational settling, cyclone dust collection, so in principle, it is gravitational settling, cyclone dust collection, three grades of series connection of gravitational settling, so dust-collecting efficiency height, secondly little because of the sub-size of single whirlwind again, cyclone dust collection efficient height, total dust-collecting efficiency improves.The other advantage of this structure is that a plurality of whirlwind are in parallel, and in the housing that exists together, can increase with whirlwind quantum count number so handle air quantity.And the system radiating area reduces, and system radiating is reduced.
The technical solution adopted in the present invention is: a kind ofly collect the efficient cyclone dust-precipitator that gravity gathers dust, comprise the housing and whirlwind that have air inlet, air outlet, be provided with ash hole in lower part of frame, inside at housing is divided into one-level gravity settling chamber and secondary gravity settling chamber by the sub-upper face plate of whirlwind, the sub-lower face plate of whirlwind and damping sheet with the cavity in the housing, air inlet is connected with described one-level gravity settling chamber, and air outlet and ash hole are connected with described secondary gravity settling chamber;
Described one-level gravity settling chamber is surrounded by the sub-upper face plate of whirlwind, the sub-lower face plate of whirlwind and damping sheet and forms, the sub-upper face plate of described whirlwind, the sub-lower face plate of whirlwind are respectively horizontal by the acute angle setting, damping sheet is arranged on the side away from air inlet, and offers the outlet of gravitational settling dust at described damping sheet;
Described one-level gravitational settling is indoor to be provided with a plurality of whirlwind, the sub-volume inside of whirlwind is cyclone separating chamber, whirlwind is fixedly connected between the sub-upper face plate of whirlwind and the sub-lower face plate of whirlwind, the axis of whirlwind is respectively perpendicular to the sub-upper face plate of whirlwind and the sub-lower face plate of whirlwind, it is indoor that the dusty gas import of whirlwind is positioned at the one-level gravitational settling, and the divided gas flow outlet of whirlwind upper end and the ash discharge dirt mouth of lower end all are connected with the secondary gravity settling chamber.
The sub-upper face plate of described whirlwind and the sub-lower face plate of whirlwind are parallel to each other, the sub-upper face plate of whirlwind, the sub-lower face plate of whirlwind be respectively at horizontal by 30 ° of angles, the purpose that this angle of inclination arranges be make things convenient for gravitational settling dust be convenient to be discharged by ash hole at gravity effect lower edge lower face plate.
The invention has the beneficial effects as follows:
One, the present invention, this device rationally intercepts into one-level gravity settling chamber and secondary gravity settling chamber by the sub-upper face plate of whirlwind, the sub-lower face plate of whirlwind and damping sheet with the dedusting enclosure interior, and be obliquely installed whirlwind to be distributed in the one-level gravitational settling indoor a plurality of, described one-level gravity settling chamber is surrounded by the sub-upper face plate of whirlwind, the sub-lower face plate of whirlwind and damping sheet and forms, the sub-upper face plate of described whirlwind, the sub-lower face plate of whirlwind are respectively horizontal by the acute angle setting, damping sheet is arranged on the side away from air inlet, and offers the outlet of gravitational settling dust at described damping sheet; By above architecture advances, indoor at the one-level gravitational settling, gas flow rate reduces, and large granular materials is under the gravity effect, and realization separates with gas, and simultaneously, solid particle is run into the sub-outer arm of whirlwind, loses inertia and also obtains separating, and therefore, separating effect is better; The gas of initial gross separation enters the sub-inside of whirlwind and again big dust particle is separated then, gas after the separation enters the bigger secondary gravity settling chamber in space again, gas flow rate reduces, large granular materials falls collection along the sub-upper face plate of whirlwind that tilts again under the gravity effect, this structure reaches optimal separating efficiency; And because a plurality of whirlwind to be arranged on the one-level gravitational settling indoor airtight, so system's heat insulation effect is very good.
Two, secondly, the present invention is in tilted layout whirlwind, with the axis of whirlwind respectively perpendicular to the sub-upper face plate of whirlwind and the sub-lower face plate of whirlwind, inclined installation angle with the sub-upper face plate of whirlwind, the sub-lower face plate of whirlwind is 30 ° simultaneously, this structure has guaranteed that dust separating effect under the gravity effect reaches best, therefore this structure need not to improve flow velocity and adjusts separating effect, has reduced energy consumption indirectly.
Its three, this apparatus structure is simple, easy access is easy to remove inner dust packing phenomenon, therefore the service life of having improved equipment.
