Preferably, the nozzle of the air intake pipe is bent downward.

By adopting the above technical solution, water flow into the intake pipe is reduced.

Preferably, the water supply device includes a clean water tank connected to the sewage pipe, a water storage tank connected to the clean water tank, and a circulation pump for delivering the water in the water storage tank to the spraying device.

By adopting the above-mentioned technical scheme, the sewage enters the clean water tank through the sewage pipe, flows into the water storage tank after being purified by the clean water tank, and then is pumped into the spraying device through the circulation pump, thereby achieving the recycling of water resources.

In summary, the utility model has the following beneficial effects: exhaust gas enters the inner cavity of the tower body through the intake pipe, and the water sprayed by the spraying device fully contacts the exhaust gas during the process of the exhaust gas rising from the bottom of the tower to the top of the tower. Impurities such as dust or particles in the exhaust gas are mixed into the water, and then settle to the bottom of the tower; the water mist from the sprayer will be sprayed directly to the bottom of the conical baffle, and fully contact with the exhaust gas to achieve a better purification effect; The water flow sprayed by the sprinkler will spread under the action of the baffle, and then the inner cavity of the tower body will form a ring-shaped water curtain. The purpose of making full use of water resources.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail.

This specific embodiment is only an explanation of the utility model, and it is not a limitation of the utility model. After reading this description, those skilled in the art can make modifications to the embodiment without creative contribution according to needs, but as long as it is within the utility model All new claims are protected by patent law.

A clean exhaust gas treatment tower, as shown in Figures 1 to 3, includes a tower body 1, a shower 2 and a conical baffle 4, the shower 2 is placed in the inner cavity of the tower body 1, and the shower 2 is It is hollow in the shape of a disc, the center of which is equipped with a sprayer 3 along the axial direction, an air filter plate 5 is installed on the inner wall of the tower body 1 above the sprayer 2, and an exhaust pipe 6 is integrally formed on the top of the tower body 1 .

The sprayer 2 and the sprayer 3 are connected to different pipelines. The sprayer 2 is disc-shaped and hollow inside. Its side wall and bottom wall are provided with spray holes 21 communicating with its inner cavity. The sprayer 3 is cylindrical. It is hollow, and its bottom surface has a spray hole 31 connected with its inner cavity. The sprinkler 2 is fixed with a conical baffle 4 by welding, and a through pipe 41 is installed on the top of the conical baffle 4, and the through pipe 41 runs through the conical The baffle 4 and the sprayer 3 are located in the through pipe 13, and the sprayer 2 is sleeved on the through pipe 13, so that when the water mist sprays out, it directly enters the inside of the conical baffle 4 and fully contacts with the exhaust gas, and the outside of the conical baffle 4 The wall is welded to the inner wall of the tower cavity through four fixing rods 12 . When the water spray hole 21 sprays the water flow, part of the water flow is sprayed to the inner wall of the tower body 1, and the impurities adhered to the inner wall of the tower body 1 can be washed away; the other part of the water flow flows down the outer wall of the tapered baffle 4 to form a water curtain. When the exhaust gas flows out, it must pass through the water curtain, so that the exhaust gas and water can fully contact.

The side wall of the tower body 1 extends into the air inlet pipe 7 near the bottom, and the mouth of the air inlet pipe 7 is bent downwards to prevent water flow into it; The dust is washed down by the water flow and flows into the sewage pipe 8 along the slope at the bottom of the tower, which avoids the accumulation of dust at the bottom of the tower body 1. The sewage pipe 8 is connected to the clean water tank 9, and the clean water tank 9 is connected to the water storage tank 10 through pipes, and the water storage tank 10 communicates with the sprayer 2 and the sprayer 3 respectively through two pipelines, and a circulation pump 11 is installed between the water storage tank 10 and the sprayer 2 and the sprayer 3 .

Use process: start the circulating pump 11, the water flows into the sprinkler 2 and the sprayer 3, and at the same time, the intake pipe 7 discharges exhaust gas into the tower, the sprayer 3 sprays water mist and the exhaust gas fully contacts, and the water sprayed by the sprayer 2 sprays to The inner sidewall of the tower body 1 and the outer sidewall of the tapered baffle 4 form a water curtain, and simultaneously the dust on the inner sidewall of the tower body 1 is cleaned. When the exhaust gas is discharged, it must pass through the water curtain, so that the exhaust gas and the water flow can fully contact the exhaust gas and continue to flow upwards. After being filtered by the filter air plate 5 to remove harmful substances, it is discharged through the exhaust pipe 6. The water flow will discharge the dust in the exhaust gas through the sewage outlet. , through the clean water tank 9, the dust sinks into the bottom of the clean water tank 9, and the purified water flows into the water storage tank 10, and then is drawn into the sprayer 2 and the sprayer 3 by the circulation pump 11, so as to achieve the recycling of the water flow.
