Description

Technical Field

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

[0002] The spray tower exists as a treatment equipment for environmental waste gas treatment. According to the working principle, it is divided into circulating water spray tower, alkali spray tower, acid spray tower. When dust-containing waste gas or oil-containing waste gas passes through the spray tower body, liquid medium is sprayed out from the appropriate position inside the tower body (depending on the design). Some are alkali solutions, and some are sulfuric acid solutions. If the waste gas contains acid, alkali solution spraying is selected to neutralize the acid. If the waste gas contains alkalinity, sulfuric acid solution is selected to absorb it. The specific choice of acid and alkali solution depends on the nature of the waste gas and the company's own situation. Waste gas without acid or alkali but containing oil and dust can be treated by spraying with circulating water solution.

[0003] When the waste gas in the existing spray tower is mixed with the spray liquid, most of the spray pipes are fixed, and the mixing effect is relatively general. It is inconvenient to mix the spray liquid and the waste gas well together, and it is inconvenient to evenly disperse the waste gas, which reduces the effect of waste gas treatment.

[0027] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the utility model of a spray tower for industrial waste gas treatment in conjunction with the accompanying drawings.

[0028] like Figure 1-4 As shown, a spray tower for industrial waste gas treatment of the utility model comprises a spray tower body 1 and a fixed block 13, a support plate 22 is fixedly connected to the right side of the upper end of the spray tower body 1, a motor 3 is fixedly connected to the upper part of the support plate 22, a turntable 4 is fixedly connected to the output end of the motor 3, a connecting rod 5 is rotatably connected to the front side of the turntable 4, a rack 6 is rotatably connected to the left side of the connecting rod 5, a mounting box 2 is fixedly connected to the upper part of the spray tower body 1, the inner sides of the mounting box 2 are slidably connected to the rack 6, a moving rod 9 is slidably connected to the inner part of the spray tower body 1, a gear 7 is slidably connected to the outer part of the moving rod 9, an outer side of the gear 7 is connected to a front end side of the rack 6, a cylindrical rod 10 is rotatably connected to the inner part of the fixed block 13, the upper part of the cylindrical rod 10 is fixed to the lower end of the moving rod 9, and a moving mechanism for moving the cylindrical rod 10 up and down is installed inside the fixed block 13;

[0029] The moving mechanism includes a screw nut 14 fixedly connected to the inside of the fixed block 13, a reciprocating screw 15 fixedly connected to the lower end of the cylindrical rod 10, the outside of the reciprocating screw 15 is meshed with the inside of the screw nut 14, and a connecting pipe 12 is fixedly connected to the rod wall of the cylindrical rod 10, and a plurality of evenly distributed nozzles 11 are installed below the connecting pipe 12.

[0030] The starting motor 3 drives the turntable 4 to rotate, the turntable 4 drives the connecting rod 5 to move, the connecting rod 5 drives the rack 6 to move, and under the limiting action of the installation box 2, it moves left and right, the rack 6 drives the gear 7 to rotate back and forth, the gear 7 drives the cylindrical rod 10 to rotate, when the cylindrical rod 10 rotates, it drives the reciprocating screw rod 15 to rotate, the reciprocating screw rod 15 and the screw nut 14 engage for transmission, so that the reciprocating screw rod 15 continuously moves up and down, the cylindrical rod 10 rotates while moving up and down, thereby driving the connecting pipe 12 to move up and down synchronously.
