Abstract

The utility model discloses a smoke dust filter, comprising a casing (2), a cover plate (14), a closed chamber formed by the casing (2) and the cover plate (14). The chamber is divided into the filtering area (13) and a buffer (3) connected mutually. The buffer (3) is connected with the peripheral discharge pipe (1). The filtering area (13) is divided into an ash settling basin (6) and a neutralization tank (12). The ash settling basin (6) is provided with an ash settling device (7) whose bottom is provided with a settling hole (15). The lower part of the ash settling device is soaked in the aqueous solution. The inlet of the ash settling device is connected with the peripheral dust suction cover (11). The outlet of the ash settling device (7) is connected with the peripheral blower (9). An atomizing fan (8) is arranged in the ash settling device. A bubbling pipe (5) is arranged in the neutralization tank (12). The bubbling pipe (5) is connected with the outlet of the blower (9). After the above structure is adopted, the smoke dust is absorbed and settled in atomizing through the fan at first layer and is absorbed and settled in atomizing through the bubble at the second layer. The after-treatment smoke dust is discharged from the discharge pipe via the buffer. The smoke dust filter has the advantages of simple and reasonable structure, good effect of smoke prevention and dust control and saving running cost.

Description

The filtrating smoke dust device

Technical field

The utility model relates to a kind of environmental protecting device, particularly a kind of filtrating smoke dust device that can reduce flue dust and toxic gas discharging.

Background technology

At present, in production processes such as secondary nonferrous metal pulverizing, melting and medal polish, can produce a large amount of flue dust and pernicious gas, in order to eliminate flue dust and pernicious gas, environmental administration has formulated discharge standard for this reason; Most of producers have dropped into a large amount of funds and have been equipped with environmental protection equipment in order to reach discharging standards; Because existing environmental protection equipment smoke medicining dust-removing effect is poor, the equipment operating cost is big, the enterprise less concerning scale, that benefit is relatively poor, environmental protection equipment transformation or put into operation and all will increase the weight of the burden of enterprise greatly, most of environmental protection equipments are in inactive or partly stop half-open position, cause environmental protection equipment to establish, do not have due effect just as need.Developing that a kind of production cost is low, the filtrating smoke dust device of economic operating cost, has been major tasks of government, research department and producer.

Summary of the invention

For overcoming the above-mentioned disadvantage that existing filtrating smoke dust device exists, problem to be solved in the utility model provide a kind of simple and reasonable, smoke abatement and dust control good, the filtrating smoke dust device of economic operating cost.The technical scheme that its technical problem that solves the utility model adopts comprises housing, cover plate, housing and cover plate are formed the chamber of sealing, described chamber is separated into filtering area and the buffering area that is interconnected, buffering area links to each other with the discharge pipe of peripheral hardware, filtering area is divided into ash settling basin and neutralization pond, ash settling basin is provided with the sink dust device that the bottom has sedimentation hole, the bottom of sink dust device is immersed in the aqueous solution, the sink dust device import is connected with the dust shield of peripheral hardware, the sink dust device outlet is connected with the blower fan import of peripheral hardware, be provided with misting fan blade in the sink dust device body, fan blade is connected with the motor of peripheral hardware; Be provided with the bubbling pipe that is immersed in the aqueous solution in the neutralization pond, bubbling pipe links to each other with the blower fan outlet.

In order to prevent that Chi Shui from splashing and better to absorb pernicious gas, on the bubbling pipe of neutralization pond, be provided with the splashproof net.

For the ease of the drying tunnel heating, the air inlet fire door is housed on the described gas approach, close the air inlet fire door, the flue gas of smelting furnace can make the drying tunnel temperature fast rise directly by discharging behind the drying tunnel.

After adopting said structure, the utility model directly uses with the coordinative composition of equipments that produces flue dust, flue dust is by two road smoke abatements and dust controls, first road absorbs, is deposited in the settling tank by the fan blade atomizing of settler, second road absorbs, is deposited in the neutralization pond by the bubbling atomizing, and flue dust is after treatment discharged from discharge pipe through buffering area; Have simple and reasonable, advantages such as smoke abatement and dust control good, economic operating cost.
