Description
Technical field
The invention belongs to technical field of operation, is related to a kind of separation, particularly a kind of deduster.
Background technology
Deduster is the equipment that dust is separated from flue gas.The performance of deduster with accessible gas flow,
Gas is expressed by drag losses during deduster and efficiency of dust collection.
Deduster is according to actual condition type selecting, and it is a kind of more special work that coarse granule shape dust mixes with ultrafine dust
Condition；Such as sandblasting, ball blast working condition, part steel sand and the ultrafine dust mixing ratio method of double differences 10：1 or so；Aluminium, magnesium product difference in specific gravity
Away from bigger.
Traditional deduster is handled using classification, and Ji Qian roads set dry type vortex pretreating device, rear road high efficiency filter again
Or spray；Sandblasting cleaner (application publication number CN104907940A), the aerodynamic sand blasting recorded such as Chinese patent literature
Dedusting work station (Authorization Notice No. CN201752864U).There is space-consuming is big, dedusting resistance is high for traditional deduster
Problem, and then influence efficiency of dust collection.Traditional deduster is when handling dust containing magnalium, because steel sand runs at high speed collision friction
Spark is easily produced, causes magnalium dust detonation risk to be present.
The content of the invention
The present invention proposes a kind of deduster, and the technical problem to be solved in the present invention is how to propose another suitable spray
The deduster of the working conditions such as sand, ball blast.
The technical problems to be solved of the present invention can be realized by following technical proposal：A kind of deduster, including gravity
Settle pre-separation pipe, cyclone dust collector and cistern；Gravitational settling pre-separation pipe is vertically arranged, cyclone dust collector have into
Wind interface, air-out interface and dust flue；Gravitational settling pre-separation pipe is located at the side of cyclone dust collector, gravitational settling pre-separation
The upper port of pipe is connected with the air intake interface of cyclone dust collector；Gravitational settling pre-separation pipe and cyclone dust collector are respectively positioned on
Above cistern, the lower end of gravitational settling pre-separation pipe and the dust flue of cyclone dust collector are stretched into the cavity volume of cistern；Rotation
The inner cavity top of wind dust arrester is provided with shower nozzle；Air inlet tube is connected with the bottom side wall of gravitational settling pre-separation pipe.
The air-out interface tandem of cyclone dust collector has moisture separation device and blower fan in this deduster；Held in cistern
There is water, the liquid level of water divides in advance higher than the lower port and the lower port higher than dust flue, i.e. gravitational settling of gravitational settling pre-separation pipe
Water seal state is in from the lower port of pipe and the lower port of dust flue, avoids air from entering from above-mentioned two lower port.
Air inlet tube produces storehouse with dust gathering arrester or smog and is connected；In fan operation, air-flow flows to whirlwind from air inlet tube
The air-out interface of dust arrester.When containing dust in the air-flow for entering this deduster, i.e., dust enters gravitational settling pre-separation
Guan Hou, because the cross-sectional area of gravitational settling pre-separation tube cavity is much larger than the cross-sectional area of air inlet tube, thus air-flow
Flow velocity and pressure reduce suddenly, and under gravity, the dust for declining naturally and settling falls into cistern to heavier granule dust
Interior and dust is mixed into water, and then avoids dust from kicking up again.
Lighter dust enters in cyclone dust collector with air-flow；The water sprayed from shower nozzle is mixed into air-flow, i.e., is being revolved in water
It is mixed at the top of wind dust arrester in air-flow.Flow spiral containing water and dust moves downward, in the process, water and dust
Constantly mixing and water and dust constantly separate with the side wall collision of cyclone dust collector so that be mixed with the water of dust along
The side wall of cyclone dust collector is trickled downwards, is flowed into by dust flue in cistern.It follows that gravitational settling pre-separation pipe and
The dust that cyclone dust collector is isolated is mixed in the water of cistern, is both clustered together dust settling, is convenient to clean, again
Dust is avoided to kick up again.The current that shower nozzle sprays are returned in cistern, cistern is connected with shower nozzle by water pump and water pipe
Realization recycles.
Compared with prior art, gravitational settling pre-separation pipe can make dust natural subsidence in this deduster, realize pretreatment,
Preventing crude particle dust collides generation spark because of whirlwind simultaneously, and then significantly improves deduster safety in operation.Lighter powder
Dirt is separated using wet dust removal mode and using cyclone dust removal mode, is both effectively guaranteed efficiency of dust collection, is significantly reduced again
Dust explosion possibility, that is, significantly improve deduster safety in operation.
Gravitational settling pre-separation pipe and cyclone dust collector are respectively provided with the low characteristic of dedusting resistance, thus this deduster has
The advantages of dedusting resistance is low.
This deduster have selected combinations thereof scheme in numerous dedusting methods and separate mode so that this deduster is fitted
Conjunction is applied in the special operation condition that coarse granule shape dust mixes with ultrafine dust；Thus this deduster has reasonable in design excellent
Point.This deduster is especially suitable for applying in aluminium, magnesium material product is carried out the working conditions such as sandblasting, ball blast.
The gravitational settling pre-separation pipe and cyclone dust collector of this deduster share a cistern, and gravitational settling divides in advance
It is arranged on from pipe and cyclone dust collector above cistern, thus this deduster has that complete machine floor space is small, dust concentrates system
One processing, it is easy to maintenance the advantages that.
