Description
Technical field
The invention belongs to the technical field of dust source control device.Be specifically related to a kind of cold roller steel strip blowing and drawing type dust catching device, particularly about being used for controlling the dust that produces when cold-strip steel moves.
Background technology
Cold rolling mill is a final finished factory in the iron and steel enterprise, is the factory of becoming a useful person that product, goes out benefit, and no matter requiring from product quality still is that all requiring in the cold rolling mill production process must be cleaner production from environmental benefit.
There are pickling unit, smooth unit and grinding roller unit etc. in the main position that produces dust in the cold rolling mill production process, and wherein the flue dust of the straightener of pickling unit, the generation of bonding machine place is the most serious.Because band after steel comes out from the hot rolling unit, enters water injector, then is rolled into band coil of strip and slowly cooling, just during this period of time, belt steel surface is oxidized and generate iron scale.When the pinch roll straightener of being with steel by pickling unit arrival end, seven-roll Abramsen machine and flash butt welder, belt steel surface is through technical process such as extruding, stretching, bending, alignings, the iron scale of belt steel surface comes off, thereby produce a large amount of airborne dusts, its concentration can reach 5mg/L, for getting rid of these dusty gases, generally dust separation system need be set.
In order to capture the ash-laden gas that distributes, on the pinch roll straightening machine body, establish upper and lower air-suction cover usually, the bonding machine top is provided with air-suction cover, and a semitight cover is established in the seven-roll Abramsen machine top, and air-suction cover is established in the below.The dusty gas that band steel aligning, welding, drawing process are produced is pooled in the air main and enters in the pulse blowing bag type dust precipitator after separately air-suction cover captures and purifies, and is drained into outdoor then by blower fan.The dust that falls from deduster bottom ash bucket is collected in the ash-pit, regularly transports, and recycles.
But the dust Control effect of the pickling unit of cold rolling mill and smooth unit is unsatisfactory at present, reason is that the loosening iron scale of belt steel surface comes off along Cheng Fasheng owing to vibrate in the process of band steel high-speed cruising, promptly not only to produce a large amount of airborne dusts at straightener, bonding machine and seven-roll Abramsen machine place, but in various degree airborne dust is all arranged on the entire belt steel, the dirt source range is wide.Therefore it is not enough only at straightener, bonding machine and seven-roll Abramsen machine etc. air-suction cover being set everywhere.But arrange all that on whole production line air-suction cover is irrational, this has increased cost of investment on the one hand, and influences production technology, and the required air quantity of dedusting significantly increases on the other hand, thereby has improved the consumption of electric energy, has increased operating cost.
Summary of the invention
Task of the present invention provides a kind ofly can dwindle the dirt source range, to effective, simple in structure, the reliable cold roller steel strip blowing and drawing type dust catching device of dust source control.
For realizing above-mentioned task, the technical solution used in the present invention is: this device is made up of top nozzle, following nozzle and air-suction cover; 1～3 top nozzle and 1～3 following nozzle are separately positioned on the above and below of being with steel the same side, and the setting angle of top nozzle and following nozzle is adjustable, and top nozzle is connected with the Compressed Gas source of the gas by pipeline with following nozzle; Air-suction cover is arranged on the opposite side of band steel, and air-suction cover is relative with following nozzle with top nozzle, and air-suction cover is connected with cleaning shaft.
The gauge pressure of described Compressed Gas source of the gas is 0.05～2MPa.
The setting angle of described top nozzle 1 and following nozzle 2 is: vertical guide angle α is that 0～80 °, horizontal plane angle β are 15～165 °.
Because adopt technique scheme, top nozzle is connected with the Compressed Gas pipeline with following nozzle, when being with the steel high-speed cruising, upper and lower nozzle is worked simultaneously, and the Compressed Gas that sprays from upper and lower nozzle is with the very high upper and lower surface of speed difference wash zone steel.Utilize the souring of Compressed Gas, make the loosening iron scale in band steel upper and lower surface take place effectively to come off, under the effect of Compressed Gas, rush at the air-suction cover that the opposite is connected with cleaning shaft, thus with dust source control in limited scope, be convenient to capture, the dirt source is controlled effectively.In addition, can suitably increase the quantity of top nozzle and following nozzle for band steel, to reach desirable capture effect than broad.
The advantage of this capturing device is: 1) utilize the souring of Compressed Gas, make the iron scale of band on the steel take place effectively to come off, and the dust source control that will produce dust is in limited scope, thereby can control the dirt source effectively; 2) because the dirt source is controlled in the limited scope, the exhausting amount can reduce greatly, can save electric energy; 3) pressure of the setting angle of upper and lower nozzle and Compressed Gas can be regulated arbitrarily, has guaranteed the control effect to the dirt source; 4) simple in structure, easy to maintenance, and easily on existing dust pelletizing system, transform, help promoting and industrialization.
Therefore, the present invention has and can dwindle dirt source range, effective, simple in structure, the reliable characteristics of dust source control.
