[0002] Acid mist waste gas is a harmful gas produced in the chemical production process. If it is discharged directly, it will pollute the environment. Therefore, a special waste gas cleaning device is needed to clean the acid mist waste gas, and then discharge the treated gas to avoid polluting the environment.

[0003] When the existing Venturi type acid mist exhaust gas cleaning device is in use, after the acid mist gas is mixed with water, it is only separated into gas and liquid by a single cyclone separator, so that the separation effect of the acid mist chemicals dissolved in the water and the gas cannot be guaranteed, resulting in a large amount of acidic liquid in the discharged gas, thereby polluting the environment.

Through the provision of a gas-liquid separator, a motor, a rotating cone and separation blades, after the gas and liquid mixture enters the gas-liquid separator from the diffusion tube, the rotating separation blades can rotate the liquefied acidic liquid and throw it onto the inner wall of the gas-liquid separator, thereby performing an initial gas-liquid separation on the gas. The separated gas enters the cyclone separator for further separation, thereby ensuring the liquid separation effect and avoiding environmental pollution after the gas is discharged, and can effectively solve the problems in the background technology.

[0006] Furthermore, a water inlet pipe is arranged on the outer ring side of the throat pipe, and a shrink tube is arranged on the upper end of the throat pipe.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4The present embodiment provides a technical solution: a venturi-type acid mist waste gas cleaning device, comprising a throat pipe 2, a diffusion pipe 4 is arranged at the lower side of the throat pipe 2, a gas-liquid separator 5 is arranged at the lower end of the diffusion pipe 4, a motor 12 is arranged inside the gas-liquid separator 5, a rotating cone 11 is arranged on the upper side of the motor 12, and a splitting blade 13 is arranged on the rotating cone 11, a connecting pipe 6 is arranged outside the gas-liquid separator 5, a pressurized fan 10 is arranged at one end of the connecting pipe 6, a cyclone separator 7 is arranged at the air outlet end of the pressurized fan 10, a gas discharge pipe 8 is arranged on the upper part of the cyclone separator 7, and a liquid gathering bucket 9 is arranged at the lower side of the cyclone separator 7.

[0020] like Figure 1-4 As shown, the cyclone separator 7 separates the liquid from the gas and accumulates them in the liquid gathering bucket 9, and is transported away through the connecting pipe at the lower side of the liquid gathering bucket 9. The acid mist gas enters the throat 2 through the contraction tube 1. Due to the arrangement of the contraction tube 1 and the throat 2, the gas flow rate flowing inside the throat 2 is increased, so that the water inside the water inlet pipe 3 connected to the outside of the throat 2 is sucked into the inside of the throat 2. Then the gas and the water are mixed and flow into the diffusion tube 4. The gas flow rate is reduced, and the acid gas dissolved in the water can drip The acid liquid falls on the separation blades 13 of the rotating cone 11, and the motor 12 drives the rotating cone 11 and the separation blades 13 to rotate rapidly, thereby throwing the acid liquid on the separation blades 13 onto the inner side of the gas-liquid separator 5. The acid liquid can flow along the gas-liquid separator 5 to the lower part of the gas-liquid separator 5 and be discharged through the pipeline. After the initial gas-liquid separation, the booster fan 10 pressurizes the gas and sends it to the inner side of the cyclone separator 7, and then a secondary separation can be performed to ensure the gas-liquid separation effect and avoid the gas being discharged into the environment to cause pollution.

[0021] A water inlet pipe 3 is arranged on the outer ring side of the throat pipe 2, and a shrink tube 1 is arranged on the upper end of the throat pipe 2.

[0022] The contraction tube 1 is fixedly connected to the throat tube 2 , and the throat tube 2 is fixedly connected to the diffusion tube 4 .

[0023] The diffusion tube 4 is fixedly connected to the gas-liquid separator 5 , and the housing of the motor 12 is fixedly connected to the inner side of the gas-liquid separator 5 .

[0024] The pressure fan 10 is fixedly connected to the cyclone separator 7 , and the gas discharge pipe 8 is fixedly connected to the cyclone separator 7 .

[0025] The liquid collection bucket 9 is fixedly connected to the cyclone separator 7 , and the connecting pipe 6 is fixedly connected to the pressurizing fan 10 .

[0026] The working principle of the Venturi type acid mist waste gas cleaning device provided by the utility model is as follows: Figure 1-Figure 4As shown, when in use, the acid mist gas enters the throat 2 through the contraction tube 1. Due to the arrangement of the contraction tube 1 and the throat 2, the gas flow rate flowing inside the throat 2 is increased, and the water inside the water inlet pipe 3 connected to the outside of the throat 2 is sucked into the inside of the throat 2. Then the gas is mixed with the water and flows into the diffusion tube 4. The gas flow rate is reduced, and the acid gas dissolved in the water can drip on the separation blades 13 of the rotating cone 11. The motor 12 drives the rotating cone 11 and the separation blades 13 to rotate rapidly, and then the acidic liquid on the separation blades 13 is thrown onto the inner side of the gas-liquid separator 5. The acidic liquid can flow along the gas-liquid separator 5 to the lower part of the gas-liquid separator 5 and be discharged through the pipeline. After the initial gas-liquid separation, the booster fan 10 pressurizes the gas and sends it to the inside of the cyclone separator 7, and then a secondary separation can be performed to ensure the gas-liquid separation effect and avoid gas discharge into the environment to cause pollution.
