Description

Deduster

Technical field

The utility model 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 accessible gas flow of the performance of deduster, 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 is mixed 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, Ji Qian roads setting 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 occupied space 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, since steel sand runs at high speed collision friction Spark is easily generated, leading to magnalium dust, there are detonation risks.

Invention content

The utility model proposes a kind of deduster, the technical problems to be solved in the utility model is how to propose another kind It is suitble to the deduster of the working conditions such as sandblasting, ball blast.

The technical problems to be solved of the utility model can be realized by following technical proposal：A kind of deduster, including Gravitational settling pre-separation pipe, cyclone dust collector and cistern；Gravitational settling pre-separation pipe is vertically arranged, cyclone dust collector tool There are air inlet interface, outlet air interface and dust flue；Gravitational settling pre-separation pipe is located at the side of cyclone dust collector, and gravitational settling is pre- The upper port of separating pipe is connected with the air inlet interface of cyclone dust collector；Gravitational settling pre-separation pipe and cyclone dust collector are equal Above cistern, the lower end of gravitational settling pre-separation pipe and the dust flue of cyclone dust collector stretch into the cavity volume of cistern It is interior；The inner cavity top of cyclone dust collector is equipped with nozzle；Air inlet is connected on the lower end side wall of gravitational settling pre-separation pipe It takes over.

The outlet air interface tandem of cyclone dust collector has moisture separation device and wind turbine in this deduster；It is 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 The lower port of lower port and dust flue from pipe is in water seal state, and air is avoided to enter from above-mentioned two lower port.

Air inlet tube generates storehouse with dust gathering arrester or smog and is connected；In fan operation, air-flow flows to whirlwind from air inlet tube The outlet air interface of dust-extraction unit.When containing dust in the air-flow for entering this deduster, i.e., dust enters gravitational settling pre-separation Guan Hou, since 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 the effect of gravity, the dust for declining naturally and settling falls into cistern to heavier granule dust Interior and dust is mixed into water, and then dust is avoided to raise again.

Lighter dust enters with air-flow in cyclone dust collector；The water sprayed from nozzle is mixed into air-flow, i.e., is being revolved in water It is mixed into air-flow at the top of wind dust-extraction unit.Flow spiral containing water and dust moves downward, in the process, water and dust Constantly mixing and water and dust is constantly collided with the side wall of cyclone dust collector and is detached so that be mixed with the water of dust along The side wall of cyclone dust collector trickles downwards, is flowed into cistern by dust flue.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 raise again.The flow that nozzle sprays is returned in cistern, cistern is made to be connected with 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, Prevent crude particle dust collides generation spark, and then significantly improve deduster safety in operation due to whirlwind simultaneously.Lighter powder Dirt is detached using wet dust removal mode and using cyclone dust removal mode, is not only effectively guaranteed efficiency of dust collection, but also significantly reduce Dust explosion possibility significantly improves 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 has selected said combination scheme in numerous dedusting methods and separate mode so that this deduster is fitted Conjunction is applied in the special operation condition mixed in coarse granule shape dust with ultrafine dust；Thus this deduster has the excellent of reasonable design 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 mounted on above cistern from pipe and cyclone dust collector, thus this deduster is small with complete machine floor space, dust concentrates system One processing, it is easy to maintain the advantages that.
