Description

Technical Field

[0001] The utility model relates to the technical field of industrial waste gas treatment, in particular to a spray tower for industrial waste gas treatment. Background Technique

[0002] Industrial waste gas refers to the general term of various pollutant-containing gases discharged into the air generated during fuel combustion and production processes in enterprise factory areas. In existing industrial waste gas treatment, the spray adsorption method is mostly used. There is a filler in the spray tower, and then the adsorption liquid is sprayed from the upper part through the filler, and then the pollutants in the waste gas are chemically adsorbed.

[0003] At present, although the existing spray tower can achieve the basic spray adsorption function, since most traditional spray towers are provided with a single spray head at the top, such a setting will cause dead corners in some areas during the spraying process, resulting in some fillers at the bottom being unable to effectively contact the spray liquid completely, thus causing waste of the adsorption liquid and uneven spraying problems. Therefore, there is an urgent need for a spray tower for industrial waste gas treatment. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to provide a spray tower for industrial waste gas treatment.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A spray tower for industrial waste gas treatment includes a spray tower body. A plurality of annular grooves are opened inside the spray tower body. A first partition net and a second partition net are respectively installed in each annular groove in a limited way. Above the first partition net, there is a second spray rack, and a first spray rack is installed at the bottom of the first partition net in a limited way. Both the first spray rack and the second spray rack are connected to a reaction liquid water tank through water pipes;

[0007] On one side of the outside of the spray tower body, there is a drive cabin. A double-headed motor is installed in the middle of the drive cabin. The drive shafts at both ends of the double-headed motor are respectively rotatably installed on the top and bottom walls of the drive cabin, and drive gears are installed on the drive shafts at both ends of the double-headed motor. The drive gears are respectively installed in gear grooves opened on the outer wall of the spray tower body in a limited rotation way and are respectively drivingly connected to the first partition net and the second partition net.

[0008] In addition, a preferred structure is that an air inlet pipe is provided on one side of the bottom of the spray tower body, and an air outlet pipe is provided at the top.

[0009] In addition, a preferred structure is that a reaction liquid water tank is provided on one side of the outside of the spray tower body. A water pipe is connected to the upper part of the reaction liquid water tank, and the water pipe is respectively connected to the first spray rack and the second spray rack.

[0010] In addition, a preferred structure is that outer toothed rings are installed on the outer sides of the first partition net and the second partition net, and the outer toothed rings are installed in a ring groove formed in the inner wall of the spray tower body in a limiting and fitting manner, and a gear groove is formed in one side of the ring groove, and one side of the gear groove communicates with the drive cabin.

[0011] In addition, a preferred structure is that drive gears are installed in the gear grooves in a limiting and rotating manner, and one side of the drive gear is meshed and connected with the tooth grooves of the outer toothed rings.

[0012] In addition, a preferred structure is that stirring rods are installed on one side above the first partition net and the second partition net through mounting seats.

[0014] The beneficial effects of the present utility model are as follows:

[0015] In the present utility model, by providing multiple layers of partition nets and placing fillers, the tower body is divided into two reaction areas. The spray racks correspondingly arranged at the bottom of the partition nets can effectively increase the spray reaction efficiency of each layer of filler area. Moreover, the drive cabin drives each layer of partition net to rotate through a double-headed motor inside to drive the fillers to move. During the movement of the fillers, they will come into contact with and be stirred by the stirring rods, effectively increasing the gas-liquid contact area on the surface of the fillers and increasing the disturbance between the gas and liquid phases. This helps to reduce the mass transfer resistance and enables the waste gas to contact the reaction liquid more fully. BRIEF DESCRIPTION OF THE DRAWINGS
