Background technology
When blast furnace front tapping and iron mouth carry out wind locking mouthful, flue dust is larger, and only not reaching by wind dedusting progress dedusting operation will Ask, easily cause that stokehold soot emissions are exceeded, the influence to whole environment is larger, the particularly occupation to stokehold operating personnel is good for Health is affected greatly, and whole environmental protection is caused harm.
The content of the invention
The present invention provides dust removal installation before a kind of State of Blast Furnace, the purpose is to strengthen the dust collection capacity of stokehold flue dust, prevents cigarette Dirt spreads.
To achieve these goals, the technical scheme taken of the present invention is:
Wind-force dust arrester, described State of Blast Furnace are provided with before dust removal installation before the State of Blast Furnace of the present invention, described State of Blast Furnace It is preceding to be provided with pneumatic nebulization dust collect unit by water.
Water inlet manifold of the described pneumatic nebulization dust collect unit by water provided with water under high pressure, the air inlet pipe of pneumatics wind;Described height After the water inlet manifold of pressure water is connected with the air inlet pipe of pneumatics wind, pneumatic nebulization supply mains is formed, on pneumatic nebulization supply mains Provided with multiple shower nozzles.
Described shower nozzle is provided with nozzle, and described nozzle is Laval nozzle.
The quantity of described nozzle is individual.
On the water inlet manifold of the water under high pressure before the water inlet manifold of described water under high pressure is connected with the air inlet pipe of pneumatics wind, press Water (flow) direction sets gradually aqueduct valve one and aqueduct valve two;Described aqueduct valve one is switch valve, described water pipe valve Men Erwei flow control valves.
The air inlet pipe of described pneumatics wind is two, is connected respectively with the water inlet manifold of water under high pressure.
Pneumatics air-valve one and pneumatics air-valve two are set respectively in the air inlet pipe of the pneumatics wind described in two.
Described pneumatic nebulization supply mains is galvanized pipe.
Described pneumatic nebulization supply mains is connected with shower nozzle by hose connector.
The present invention uses above-mentioned technical proposal, effectively can carry out atomization process to the abnormal flue dust in stokehold, reduce stokehold cigarette The airborne dust of dirt and diffusion, improve the harm of the working environment and reduction of stokehold to stokehold Health Status For Workers Exposed;It is installed, safeguards letter Singly, conveniently, preferably, Meteorological is relatively low, can be widely popularized for effect;Improvement expenses is low:Material requested is only several valves, appropriate Laval nozzle, galvanized pipe, the connection of some elbows;It is practical:Nebulization dust can be carried out, flue dust row is effectively reduced Put, improve operating environment and ensure that operating personnel's is healthy;Easy to maintenance, cost is low, is hardly damaged, durable in use.Should Warning device material requested is simpler, is easily changed once damaging.

Marked in figure:
1st, pneumatics air-valve one, 2, pneumatics air-valve two, 3, aqueduct valve one, 4, aqueduct valve two, 5, galvanized pipe, 6, be flexible coupling Pipe, 7, shower nozzle, 8, nozzle.
Embodiment
Below against accompanying drawing, by the description to embodiment, the embodiment to the present invention makees further details of Illustrate, to help those skilled in the art to have more complete, accurate and deep reason to inventive concept of the invention, technical scheme Solution.
The structure of the present invention, is to be removed provided with wind-force before dust removal installation before a kind of State of Blast Furnace, described State of Blast Furnace as shown in Figure 1 Dirt device.
In order to solve the problem of prior art is present and overcome its defect, the dust collection capacity of enhancing stokehold flue dust is realized, is prevented The only goal of the invention of flue dust diffusion, the technical scheme taken of the present invention is:
As shown in figure 1, provided with pneumatic nebulization water dedusting dress before dust removal installation, described State of Blast Furnace before the State of Blast Furnace of the present invention Put.
The present invention is that on the basis of existing wind dedusting, as a kind of not enough supplemental facilities of wind dust collection capacity, can have What is imitated carries out atomization process to the abnormal flue dust in stokehold, reduces airborne dust and the diffusion of stokehold flue dust, improves environment and the reduction of stokehold The possibility of stokehold operating personnel's occupational health hazards.The erection of equipment is simple and convenient, safeguards simple, effect is preferable, Meteorological It is relatively low, it can be widely popularized.The beneficial effects of the invention are as follows:
1st, improvement expenses is low:Material requested is only several valves, Laval nozzle 20, a diameter of 4cm galvanized pipes, some Elbow is connected;
2nd, it is practical:Nebulization dust can be carried out, soot emissions are effectively reduced, improves operating environment and shield operation Personnel's occupational health;
3rd, easy to maintenance, cost is low, is hardly damaged, durable in use;The warning device material requested is simpler, once damage It is easily changed.
Water inlet manifold of the described pneumatic nebulization dust collect unit by water provided with water under high pressure, the air inlet pipe of pneumatics wind;Described height After the water inlet manifold of pressure water is connected with the air inlet pipe of pneumatics wind, pneumatic nebulization supply mains is formed, on pneumatic nebulization supply mains Provided with multiple shower nozzles 7.
