The gas is generally cleaned and cooled by adopting a special tower, the tower is generally characterized in that gas enters the equipment from the lower part and is discharged from the top, water is sprayed from a spray head arranged on the upper part, a filler is arranged in the middle, the water is sprayed on the filler to flow downwards more uniformly, the gas breaks a liquid level layer from the lower part to be cooled and washed for the first time, and the gas enters the filler layer upwards to purify the gas and be cooled further. The disadvantage of this structure is that: the water is sprayed out by the spray head, the central water quantity of the spray head is large, the water and air bias flow, the temperature reduction and the air washing effects are not ideal due to the fact that the water and air flow are large, dust or other substances in the air are adhered to the filler through the filler layer, the filler is easy to agglomerate and block, the service cycle is short, the water consumption is large, and the filler is required to be cleaned and stopped.

Disclosure of Invention

The utility model aims to solve the technical problems and provide the spray device of the gas washing tower, wherein the spray device comprises an upper layer of spray nozzles for spraying in a fine line and a lower layer of spray nozzles for spraying in a fine line and a venturi spray, and the spray device is characterized in that the spray device is in full contact with water vapor in the layer, has wide and uniform contact surface and has good cooling and gas washing effects.

In order to achieve the technical purpose and meet the technical requirements, the utility model adopts the technical scheme that: the utility model provides a spray set of gas washing tower, includes the tower body, its characterized in that: the tower body inner chamber upper portion symmetry is provided with the spray assembly, and the lower part is provided with the dust fall subassembly, the spray assembly includes the inlet tube, the inlet tube middle part is provided with the spray pipe, spray pipe both ends symmetry is provided with first shower, inlet tube both ends symmetry is provided with the second shower, first shower, second shower front end are provided with the nozzle, the dust fall subassembly includes a plurality of angle tower layers.

Preferably: the water inlet pipe and the water spraying pipe are arranged in a crisscross manner.

Preferably: the first spray pipe and the second spray pipe are arranged in a U shape.

Preferably: the angle tower layer comprises a plurality of angle steels which are arranged in a zigzag manner.

Preferably: the two adjacent layers of the distributors are staggered at an angle of 45 degrees.

Compared with the traditional structure, the utility model has the beneficial effects that: the structure design is reasonable, the use is convenient, the space at 6000-7000 (mm) at the upper part of the gas washing and cooling tower adopts venturi process design, the upper layer nozzle sprays downwards in a fine line mist form, the lower layer nozzle sprays upwards in a fine line mist form to form venturi mist spray, the water and the air in the layer are fully contacted, the contact surface is wide and uniform, the cooling and gas washing effect is good, and the problem that the water and air bias flow cooling and gas washing effect is not ideal due to the fact that the filler layer is easy to block is solved; the three layers of the zigzag distributor at the lower part are staggered by 45 degrees to form a baffling space, so that the residence time of gas in the gas washing tower is prolonged, the gas washing tower is convenient to effectively spray, the gas washing effect of the gas is improved, the water consumption of the device is half of that of the original tower, and the cooling gas washing effect is excellent.
