Description
Technical Field
The utility model belongs to the technical field of the environmental protection equipment, concretely relates to spray tower system for high-efficient collection handles dust.
Background
Industrial production inevitably produces many dusts containing various pollutants. If the waste gas is directly discharged into the atmosphere without being treated, the waste gas inevitably causes serious pollution to the atmosphere, brings serious harm to human health and causes great loss to national economy. Toxic and harmful substances in the dust can enter a human body through a respiratory tract and skin, and the temporary and permanent pathological changes of systems and organs such as the breath, blood, liver and the like of the human body can be caused by long-term low-concentration or short-term high-concentration contact, so that the treatment of the dust is one of the most concerned environmental problems in the world.
The spray tower is an important device for treating dust, and after the dust enters the spray tower, the spray tower sprays corresponding detergent to absorb the dust, so that the dust content in the exhaust gas is reduced, and the pollution of industrial production to the environment is reduced. The existing spray tower system has limited dust absorption effect and poor absorption treatment effect.
SUMMERY OF THE UTILITY MODEL
The utility model provides a spray tower system for high-efficient collection handles dust, aim at solves the relatively poor problem of current spray tower washing effect.
Therefore, the utility model adopts the following technical scheme:
a spray tower system for efficiently collecting and treating dust comprises a spray tower body, wherein the top of the spray tower body is provided with an air outlet, the bottom of the spray tower body is provided with an air outlet, and the side part of the spray tower body is provided with an air inlet; the lower part in the spray tower body is provided with a horn-shaped air outlet cover, the horn mouth of the air outlet cover faces downwards, the narrow opening is connected with the air inlet of the spray tower body, and an annular air flow ascending channel is formed between the air outlet cover and the inner wall of the spray tower body; a circle of annularly arranged drain holes are formed in the peripheral edge of the air outlet cover, and the drain holes are densely distributed; a first spraying layer, a second spraying layer and a demisting layer are sequentially arranged above the gas outlet cover.
Further, the gas outlet of the spray tower body is connected with a chimney through an exhaust fan.
Furthermore, the drain hole is arranged at the lowest position of the upper edge of the air outlet cover body.
The beneficial effects of the utility model reside in that: because the gas outlet cover guides the gas flow, the travel of the gas in the spray tower body is increased, the gas is fully diffused, the contact area of the gas and the liquid mist is increased, the dust absorption efficiency is improved, the dust content in the discharged gas is reduced, and the pollution is reduced.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1 to 3, a spray tower system for collecting and treating dust efficiently comprises a spray tower body 5, wherein the top of the spray tower body 5 is provided with an air outlet 7, the bottom of the spray tower body is provided with an air outlet 8, and the side of the spray tower body is provided with an air inlet 6; a horn-shaped air outlet cover is arranged at the lower part in the spray tower body 5, the horn mouth of the air outlet cover faces downwards, the thin mouth of the air outlet cover is connected with an air inlet 6 of the spray tower body 5, and an annular air flow ascending channel is formed between the air outlet cover and the inner wall of the spray tower body 5; a circle of annularly arranged drain holes 3 are formed in the peripheral edge of the air outlet cover, and the drain holes 3 are densely distributed; a first spraying layer 9, a second spraying layer 10 and a demisting layer 11 are sequentially arranged above the gas outlet cover. The air outlet 7 of the spray tower body 5 is connected with a chimney (not shown in the figure) through an exhaust fan.
The gas outlet cover comprises a gas pipe 1 in an L shape and a gas outlet cover body 2 in a horn mouth shape, one end of the gas pipe 1 is connected with the gas outlet cover body 2, the other end of the gas pipe is provided with a connecting flange 4, the gas outlet cover is connected with a gas inlet 6 of the spray tower body 5 through the flange 4, and corners of the gas pipe 11 are in fillet transition. The edge of the air outlet cover body 2 is rolled up upwards, and the drain hole 3 is arranged at the lowest position of the upper edge of the air outlet cover body 2. The material of the gas outlet cover can be properly selected according to the acid-base property and the corrosivity of the waste gas and the cleaning solution.
After the dust enters the spray tower body 5, the gas blows to the liquid surface under the guiding action of the gas outlet cover and stimulates water mist, a small part of dust enters the water body under the inertia action and is absorbed, and a part of dust is absorbed by the stimulated water mist. Then the gas moves to the periphery along the horizontal direction and enters the middle part of the spray tower body 5 through the gas flow ascending channel between the gas outlet cover and the spray tower body 5. The first spraying layer 9 and the second spraying layer 10 spray a large amount of water mist, most dust entrained in the gas passing through the first spraying layer 9 and the second spraying layer 10 is absorbed, the gas moves upwards to pass through the demisting layer 11 to remove entrained water vapor, and then the purified gas is discharged through a chimney.
The water sprayed by the first spraying layer 9 and the second spraying layer 10 falls on the air outlet cover, converges to the lower part of the edge along the upper surface of the air outlet cover, and finally flows down through the drain holes 3 at the edge of the air outlet cover. When the water flows downwards through the drain hole 3, a cylindrical water curtain or water curtain is formed around the gas outlet cover 7, and dust entrained by gas passing through the water curtain can be further absorbed.
First spray the shower nozzle of layer 9 and second on spraying layer 10 and choose spiral nozzle for use, and spiral nozzle constantly rotates when spraying water, and spun water smoke collides each other for water smoke is even more fine and close, reduces the space, helps improving absorption efficiency. Meanwhile, the rotary spray head can also clean dust on the inner wall of the spray tower body 5.
It should be noted that the above are only some embodiments of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
