Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and particularly relates to a scrubbing tower for waste gas treatment. Background Art

[0002] Waste gas refers to harmful gases generated by humans in life or production. Directly discharging waste gas containing harmful substances without treatment will not only seriously pollute the environment but also endanger the health of inhalers. The scrubbing tower can efficiently purify the harmful components in the injected waste gas by spraying liquid solvents or absorbents.

[0003] A Chinese patent document with the authorization announcement number CN215138180U discloses a high-efficiency scrubbing tower for waste gas treatment, which includes a cylindrical water tank with an open top. The top of the water tank is hermetically connected to a vertical tower body. The bottom of the side of the tower body is vertically connected to an air inlet pipe, and the top of the tower body is connected to an exhaust pipe. Inside the tower body, a packing, a spray pipe, and a demisting layer are installed from bottom to top. The spray pipe extends outside the tower body and is connected to a water pump, and the water pump is connected to the water tank through a return pipe to form a circulation loop, so that the waste gas can be filtered, washed, demisted, etc. in the scrubbing tower.

[0004] However, in the prior art, the scrubbing tower sprays water mist through the spray pipe to wash the waste gas and reacts with the waste gas to complete the harmless treatment of the waste gas. However, when the gas flow rate is relatively fast, it is difficult to ensure that all gases can be treated before leaving the scrubbing tower. Therefore, a scrubbing tower for waste gas treatment is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a scrubbing tower for waste gas treatment.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A scrubbing tower for waste gas treatment includes a scrubbing component that can store a certain volume of waste gas treatment liquid in the scrubbing tower. A spraying component is arranged in the scrubbing component, which can spray part of the waste gas treatment liquid downward at a certain height. An air inlet component is arranged on the scrubbing component, which can fully treat the waste gas injected into the scrubbing tower.

[0008] The air inlet component includes a gas guiding member that can guide the waste gas injected into the scrubbing tower into the area where the treatment liquid is located along a fixed direction, and a rotating member that can make the waste gas fully contact the treatment liquid.

[0009] Preferably: The gas guiding member includes an air inlet hood fixedly connected to the scrubbing component. An air inlet joint is fixedly connected to the air inlet hood, and a top cover is fixedly connected above the air inlet hood.

[0010] Preferably, the rotating member includes a rotating shaft movably installed on the top cover. A motor is fixedly connected to the upper end of the rotating shaft, and a connecting pipe is fixedly connected to the lower end of the rotating shaft. A limiting seat is fixedly connected below the air inlet hood.

[0011] Preferably, an air inlet groove is integrally formed on the connecting pipe.

[0012] Preferably, the rotating member further includes a shunt combination pipe fixedly connected to the lower end of the connecting pipe, and a one-way valve is fixedly connected to the shunt combination pipe.

[0013] Preferably, the air inlet assembly further includes an exhaust joint fixedly connected to the washing assembly.

[0014] Preferably, the top cover is rotatably connected to the rotating shaft, and the connecting pipe is rotatably connected to the limiting seat.

[0015] The beneficial effects of the present utility model are as follows: It is convenient to continuously introduce the waste gas injected into the scrubbing tower into the scrubbing assembly where the waste gas treatment liquid agent is retained through the continuously rotating rotating member, so that the waste gas can fully contact the liquid agent, and after leaving the liquid agent, it contacts the liquid agent droplets sprayed by the spraying assembly, thereby ensuring that the waste gas can be fully treated in the scrubbing tower of the present utility model.

[0026] The present utility model will be further described below through embodiments in conjunction with the drawings.

[0027] As Figures 1 - 5 shown, a scrubbing tower for waste gas treatment includes a washing assembly 1 that can store a certain volume of waste gas treatment liquid in the scrubbing tower. A spraying assembly 2 is arranged in the washing assembly 1 and can spray part of the waste gas treatment liquid downward at a certain height. An air inlet assembly 3 is arranged on the washing assembly 1 and can fully treat the waste gas injected into the scrubbing tower.

[0028] In this embodiment: The washing component 1 includes a tower body 101. A first liquid inlet joint 102 is fixedly connected to the rear of the tower body 101, a sewage discharge joint 103 is fixedly connected to the front of the tower body 101, and an overflow joint 104 is arranged above the sewage discharge joint 103. The tower body 101 provides a relatively sealed reaction space for the treatment liquid agent injected therein and the waste gas entering through the air inlet component 3. The treatment liquid agent is continuously introduced into the tower body 101 through the first liquid inlet joint 102, the dirt remaining in the tower body 101 is regularly discharged through the sewage discharge joint 103, and a certain volume of treatment liquid agent can be retained in the tower body 101 through the overflow joint 104.

[0029] In this embodiment: The spraying component 2 includes second liquid inlet joints 201 fixedly connected to both sides of the tower body 101. A hollow ring pipe 202 is fixedly connected between the second liquid inlet joints 201, and a sewage discharge joint 103 is fixedly connected to the lower side of the hollow ring pipe 202. The treatment liquid agent is introduced into the hollow ring pipe 202 through the second liquid inlet joints 201, and the treatment liquid agent injected into the hollow ring pipe 202 is discharged through the nozzles 203 and sprayed downward from a certain height above the liquid level of the treatment liquid agent retained in the tower body 101.

[0030] In this embodiment: The air inlet component 3 includes a gas guiding member that can guide the waste gas injected into this washing tower into the area where the treatment liquid agent is located along a fixed direction, and a rotating member that can make the waste gas fully contact the treatment liquid agent. The gas guiding member includes an air inlet hood 301 fixedly connected to the washing component 1, an air inlet joint 302 fixedly connected to the air inlet hood 301, and a top cover 303 fixedly connected above the air inlet hood 301. The rotating member includes a rotating shaft 304 movably installed on the top cover 303. A motor 305 is fixedly connected to the upper end of the rotating shaft 304, a connecting pipe 306 is fixedly connected to the lower end of the rotating shaft 304, a limiting seat 307 is fixedly connected below the air inlet hood 301, an air inlet groove 308 is integrally formed on the connecting pipe 306, the rotating member further includes a shunt combination pipe 309 fixedly connected to the lower end of the connecting pipe 306, a one-way valve 310 is fixedly connected to the shunt combination pipe 309, and the air inlet component 3 further includes an exhaust joint 311 fixedly connected to the washing component 1. The top cover 303 is rotatably connected to the rotating shaft 304, and the connecting pipe 306 is rotatably connected to the limiting seat 307.

[0031] The upper opening of the tower body 101 is closed by the air inlet hood 301, and it cooperates with the top cover 303 to form a relatively airtight space to accommodate the waste gas introduced into this scrubbing tower through the air inlet joint 302. The rotating shaft 304 capable of driving the connecting pipe 306 to rotate is installed through the top cover 303, and the rotating shaft 304 is driven to rotate by the motor 305. The area of the lower side surface of the air inlet hood 301 through which the connecting pipe 306 passes is closed by the limit seat 307 to prevent the waste gas in the air inlet hood 301 from leaking into the tower body 101 and to limit the movable range of the connecting pipe 306. The waste gas continuously entering the air inlet hood 301 is introduced into the interior of the connecting pipe 306 through the air inlet groove 308, so that the waste gas can enter the shunt combination pipe 309 along the connecting pipe 306. The waste gas entering the shunt combination pipe 309 can leave the air inlet assembly 3 through the one-way valves 310 whose heights are all lower than the overflow joint 104. The one-way valves 310 can also prevent the liquid agent in the tower body 101 from flowing back into the shunt combination pipe 309.

[0032] Working principle: When this scrubbing tower is installed and used for waste gas treatment, the sewage discharge joint 103 is connected to the stop valve, and each joint other than the sewage discharge joint 103 is connected to the corresponding equipment for supplying and discharging the treatment liquid agent and introducing and discharging the waste gas, so that the treatment liquid agent supplied into this scrubbing tower can enter the tower body 101 through the first liquid inlet joint 102 and the second liquid inlet joint 201 respectively, leave the tower body 101 through the overflow joint 104, and enable the waste gas to enter the air inlet assembly 3 through the air inlet joint 302 and leave the tower body 101 through the exhaust joint 311.

[0033] Due to a certain height difference between the first liquid inlet joint 102, the overflow joint 104 and the spray head 203 with a height similar to that of the second liquid inlet joint 203, the liquid agent injected into this scrubbing tower will remain at a certain height in the tower body 101, and at the same time, it will continuously turn into liquid droplets and spray downward through the spray head 203.

[0034] During this process, the motor 305 is made to drive the rotating shaft 304 to rotate. As waste gas continuously enters the air inlet hood 301, and the connecting pipe 306 transmits the rotation of the rotating shaft 304 to the shunt combination pipe 309 and the one-way valves 310 whose heights are lower than the overflow joint 104, the waste gas will enter the liquid agent through each one-way valve 310 immersed in the liquid agent and continuously rotating. After reacting with the liquid agent, it will separate from the liquid agent and then contact the liquid droplets of the liquid agent sprayed by the spraying assembly 2 until it leaves the tower body 101 through the exhaust joint 311.

[0035] The preferred embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art to which it pertains, various changes can also be made without departing from the gist of the present utility model.
