In figure, 1. fire arresters, 2. primary filters, 3. spray trash separators, 4. spray water purification installations, 5. electrostatic precipitations
Device, 6. medium effeciency filters, 7.TiO2Photocatalyst purifier, 8. anion generators.
Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
The present invention provides a kind of multistage composite filtering type weld fumes purification systems, as shown in Figure 1, including passing sequentially through
Pipeline is attached fire arrester 1, primary filter 2, spray trash separator 3, electrostatic precipitator 4, medium effeciency filter 6, TiO2Light touching
Matchmaker's clarifier 7 and anion generator 8.It is ZHQ-S gravel fire arrester that wherein fire arrester 1, which is model, and primary filter 2 is disk
Formula primary filter.
Wherein the air outlet of fire arrester 1 is connected with the air inlet of primary filter 2, the air outlet of primary filter 2 and spray
The air inlet for drenching trash separator 3 is connected, and the air outlet of spray trash separator 3 is connected with the air inlet of electrostatic precipitator 5, electrostatic precipitator
5 air outlet is connected with the air inlet of medium effeciency filter 6, the air outlet and TiO of medium effeciency filter 62Photocatalyst purifier 7 into
Air port is connected, and the air outlet of photocatalyst purifier 7 is connected with the air outlet of anion generator 8.
The bottom for spraying trash separator 3 is also connected with spray water purification installation 4 by pipeline, sprays water purification installation 4
It is interior to be filled with active carbon, it sprays and is equipped with water pump in water purification installation 4, water pump is connected to connection with spray head by return pipe.
In a kind of multistage composite filtering type weld fumes purification system of the present invention, fire arrester 1 can stop in weld fumes
Mars, prevent Mars from entering to weld fumes purification system, can will in the pipeline between fire arrester 1 and primary filter 2
The air-flow flowed out from fire arrester 1 is adjusted to uniform state, to provide for primary filter 2 stable distinguished and admirable；Rotation was just imitated
Filter can carry out primary filtration to flue dust, while to change traditional static leaf filter static for disc type primary filter
Operating condition is rotated by filter, it is ensured that when filter plane is to flue dust be in same clean conditions, this primary filter change with
Toward filter surfaces as flue dust aggregation filtering efficiency gradually decreases the persistent ailment being gradually reduced by air quantity；Spray trash separator 3 is thought
By spraying water mists in the air-flow of primary filter, water mists particle and air are come into full contact with, it can be achieved that reducing flue-gas temperature, inhaling
Water-soluble contaminants of chemical origin in attached air, a part of fine aerosol particle are formed greatly in conjunction with water mists due to spraying
Particle is finally greater than aerostatic buoyancy due to own wt, and sprays gravity and the lower landing of air velocity resultant force effect downwards.
After fire arrester 1, primary filter 2 and spray trash separator 3, flue dust bulky grain, high temperature in weld fumes and
Most small particles have been captured purification, and the dust-laden in weld fumes significantly reduces, and air humidity increases.
Spray water purification installation 4 can purify the physical particulate matter settled out in spray trash separator 3 with shower water
With the contaminants of chemical origin for being dissolved in water；It is purified simultaneously who can repeat as shower water use, saving water resource.
Electrostatic precipitator 5 can capture the particle with electrostatic in air, and medium effeciency filter 6 can capture, filter sky
Remaining particulate matter, TiO in gas2Photocatalyst purifier 7 can be reacted with chemical pollutant remaining in air, anion
Generator 8 is discharged into atmosphere after anion then is added to air.
A kind of multistage composite filtering type weld fumes purification system of the invention when in use, first connects the water inlet pipe of spray head
It is connected to running water pipe, and opens running water pipe, after spray head sprays shower water；The water pump in spray water purification installation 4 is opened, will be sprayed
Purified shower water is sent to spray head again in water drenching purification device 4；Then by the weld fumes of collection from fire arrester 1 into
Air port flows into fire arrester 1, and then weld fumes is big followed by being discharged into after each clean-up stage of weld fumes purification system
In gas.
A kind of multistage composite filtering type weld fumes purification system of the present invention, is carried out by the purification process to weld fumes
