Description

Wet type desulfurizing dust collector
Technical field
The utility model provides a kind of device that is used for boiler, especially a kind of desulfation dust-extraction device.
Background technology
At present, the dust arrester that is used for boiler is generally fiber bag precipitator, and its shortcoming is to realize the desulfurization taste removal, service life is short, and serviceability is relatively poor, complex structure, installation, maintenance is loaded down with trivial details, and equipment such as pulse valve that need be supporting with it, air pump, gas bag are invested bigger.Also have a kind of Swashing type wet dust collector, the flue gas walking resistance is big, inefficiency.A kind of granite duster is arranged again, and it is big to take up room, and efficiency of dust collection is low.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of wet type desulfurizing dust collector, to improve its serviceability.
The utility model is to realize like this, wet type desulfurizing dust collector, it has the air inlet of bending to communicate with clean room's inner chamber, there is elementary filter screen inner chamber front portion, clean room, there is secondary filter screen at the rear portion, the rear end, clean room is communicated with the gas outlet, the annular conduit of taking the water hole out of is arranged around the elementary filter screen, another annular conduit of taking the water hole out of is arranged around the secondary filter screen, spray nozzle is arranged at the inner chamber top, clean room of elementary filter screen front, another spray nozzle is arranged at the inner chamber top, clean room between two filter screens, the 3rd spray nozzle is arranged at the inner chamber top, clean room of secondary filter screen back, also have respectively towards elementary filter screen on the top of clean room's inner chamber, the torrent nozzle of secondary filter screen and another torrent nozzle, each spray nozzle is connected with water inlet pipe respectively, each torrent nozzle is connected with another water inlet pipe respectively, the mesh of elementary filter screen is greater than secondary filter screen, be communicated with sewage draining exit below the clean room, eddy current ripple dehydrator is installed in the gas outlet.
Adopt the wet type desulfurizing dust collector of said structure, simple and reasonable, invest low, desulfurization, dedusting, taste removal effect are remarkable, serviceability is good, long service life, and installation, maintenance is convenient, be specially adapted to the desulfurization and dedusting of medium small boiler, sintering furnace etc., also can be used for the exhaust-gas treatment of workshops such as cement, chemical industry.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model and operation principle.
As shown in drawings, the wet type desulfurizing dust collector of the utility model, it has the air inlet 1 of bending to communicate with clean room's 4 inner chambers, there is elementary filter screen 13 inner chamber front portion, clean room, there is secondary filter screen 11 at the rear portion, the rear end, clean room is communicated with gas outlet 9, around the elementary filter screen 13 annular conduit 14 of taking the water hole out of is arranged, another annular conduit 12 of taking the water hole out of is arranged around the secondary filter screen, spray nozzle 2 is arranged at the inner chamber top, clean room of elementary filter screen front, another spray nozzle 6 is arranged at the inner chamber top, clean room between two filter screens, the 3rd spray nozzle 8 is arranged at the inner chamber top, clean room of secondary filter screen back, also have respectively towards elementary filter screen on the top of clean room's inner chamber, torrent nozzle 3 and another torrent nozzle 7 of secondary filter screen, each spray nozzle is connected with water inlet pipe 5 respectively, each torrent nozzle is connected with another water inlet pipe 16 respectively, the mesh of elementary filter screen is greater than secondary filter screen, be communicated with sewage draining exit 15 below the clean room, eddy current ripple dehydrator 10 is installed in the gas outlet.
During use, the floss hole of air inlet and boiler is linked together, gas outlet and chimney lower inlet link together.Each water inlet pipe is connected with jet pump, pressurized tank or elevated tank, and the water that enters each water pipe can be limewash or alkali lye, and hydraulic pressure is 2-4 atmospheric pressure.Boiler smoke enters the clean room through air inlet, in this course, because air inlet bending, therefore the heavier dust granules in the flue gas is thrown toward air inlet, clean room's inwall and descends under the action of the centrifugal, because of clean room's inner chamber bigger, flue gas flow rate slows down, the dust in flue gas particle fully contacts, collides with the high-pressure water mist of spray nozzle ejection, and is poly-with water-setting, below falling.The water that the apopore of annular conduit flows out makes the mesh of filter screen form moisture film, water smoke, less dust in the flue gas is in process of flowing backward during through moisture film, particle greater than mesh is directly blocked by filter screen, swept away by water, the tiny particle of part soaks into through water smoke, moisture film, being captured falls, and finishes primary purifying.Ash-laden gas further flows backward, and during through secondary filter screen, because the mesh of this filter screen is finer and closely woven, the flue dust in the ash-laden gas further is captured, and is further purified.In said process, reactions such as limewash or alkali lye and sulfur in smoke, carbon monoxide remove it.After this, during air-flow process eddy current ripple dehydrator torrent 10 torrent of band water, dehydrated, demist, the gas after dedusting, desulfurization enters chimney, discharges from the chimney outlet at last.
The sewage draining exit of liquid below the clean room that is mixed with dust discharged, and can enter pollution discharge pond, post precipitation, but liquid recycling.
Because the filter screen adsorptivity is strong, after every work a period of time, can open the torrent nozzle each filter screen is washed.The work of torrent nozzle can be controlled by the magnetic valve under the time relay control.
