Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a waste gas treatment device. Background Technology

[0002] In many industrial production processes, the waste gas often contains acidic or alkaline gases, such as hydrogen sulfide and ammonia. These acidic and alkaline waste gases are harmful to the environment and human health. If these acidic and alkaline waste gases are directly discharged, they will produce acid mist with strong corrosiveness and toxicity. This acid mist will not only cause huge pollution to the workplace, but also cause acid deposition in the atmosphere. Therefore, the waste gas needs to be treated before being discharged to reduce the harm to the environment.

[0003] Traditional waste gas treatment devices often suffer from uneven spraying and insufficient gas-liquid contact during the spraying process, resulting in low waste gas treatment efficiency and difficulty in meeting increasingly stringent environmental protection requirements. Specifically, because the flow path of waste gas within the treatment device is relatively fixed, and the distribution of the sprayed liquid cannot completely cover the entire treatment space, some waste gas fails to make sufficient contact with the sprayed liquid, thus affecting the purification effect. Utility Model Content

[0006] (II) Technical Solution

[0008] Preferably, the auxiliary spray assembly includes a connecting bracket and several gas-liquid mixing components. The middle part of the connecting bracket is sleeved on and fixedly connected to the rotating shaft. The connecting bracket extends outward with multiple equally spaced connecting arms. The end of each connecting arm away from the center of the connecting bracket is fixedly connected to the middle part of the adjacent gas-liquid mixing component.

[0010] (III) Beneficial Effects

[0011] Compared with the prior art, the present invention provides a waste gas treatment device with the following advantages:

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 and Figure 2 An exhaust gas treatment device includes a body 10, at least one atomizing nozzle 20, a motor 30, a rotating shaft 40, and an auxiliary spraying assembly 50. Exhaust gas can be input at the lower end of the body 10, and treated exhaust gas can be output at the upper end of the body 10. The atomizing nozzle 20 is mounted on the body 10 and extends into the inner cavity of the body 10. The atomizing nozzle 20 can introduce an acid-base neutralization solution via an external hose and pump and spray it onto the exhaust gas input into the inner cavity of the body 10. The motor 30 is mounted on the top of the body 10, and the output end of the motor 30 is connected to the upper end of the rotating shaft 40. The rotating shaft 40 is rotatably driven by the motor 30 and is located in the middle of the body 10. The auxiliary spray assembly 50 is sleeved on the outside of the rotating shaft 40 and fixedly connected to it, so that the auxiliary spray assembly 50 can be driven to rotate and set in the inner cavity of the body 10. By setting the rotatable auxiliary spray assembly, the spray liquid is more evenly distributed in the inner cavity of the exhaust gas treatment device, effectively avoiding the problem of uneven spraying in traditional devices and ensuring full contact between exhaust gas and spray liquid.

[0019] In this embodiment, the machine body 10 may include a processing chamber 11, an upper cover 12, a lower cover 13, an air outlet 14, an air inlet 15, and a filter screen 16. The upper cover 12 and the lower cover 13 are respectively sealed to the top and bottom of the machine body 10. The air outlet 14 and the air inlet 15 are respectively formed on the upper cover 12 and the lower cover 13 and communicate with the inner cavity of the machine body 10. The filter screen 16 is detachably installed at the bottom of the machine body 10, and the exhaust gas input into the inner cavity of the machine body 10 through the air inlet 15 can first flow through the filter screen 16 for filtration, so that larger particles in the exhaust gas are blocked by the filter screen 16.

[0020] See Figure 3The auxiliary spray assembly 50 includes a connecting bracket 51 and several gas-liquid mixing components 52. The middle part of the connecting bracket 51 is sleeved on and fixedly connected to the rotating shaft 40. Multiple equally spaced connecting arms extend outward from the connecting bracket 51. The end of each connecting arm furthest from the center of the connecting bracket 51 is fixedly connected to the middle of the adjacent gas-liquid mixing component 52, so that the several gas-liquid mixing components 52 are radially equally spaced along the rotating shaft 40. Multiple spaced porous baffles 521 are formed on the upper and lower sections of the gas-liquid mixing components 52. The porous baffles 521 formed on the gas-liquid mixing components 52 are symmetrically distributed with respect to the horizontal plane where the center of the gas-liquid mixing component 52 is located. The length of the porous baffles 521 decreases sequentially upwards or downwards from the center, and each porous baffle 521 is inclined at a certain angle towards the center of the gas-liquid mixing component 52. The surface of the porous baffle 521 is covered with numerous small holes. These holes not only increase the contact area between the gas-liquid mixer 52 and the exhaust gas and spray liquid, but also allow the exhaust gas to come into more thorough contact with the spray liquid as it passes through the baffle. Each porous baffle 521 is tilted at a certain angle towards the center of the gas-liquid mixer 52. This tilting design guides the exhaust gas to form eddies and turbulence as it passes through the baffle. The formation of eddies and turbulence increases the mixing degree between the exhaust gas and the spray liquid, allowing harmful substances in the exhaust gas to come into more uniform contact with the spray liquid, thereby improving the purification effect. The length of the multiple porous baffles 521 decreases sequentially from the center upwards or downwards, and they are symmetrically distributed with respect to the horizontal plane where the center of the gas-liquid mixer 52 is located. This layout allows the exhaust gas to experience a change in airflow channel from wide to narrow and then from narrow to wide as it passes through the gas-liquid mixer 52. This change helps optimize the gas-liquid mixing path, enabling the exhaust gas and spray liquid to form a more complex and effective contact pattern during the mixing process. By increasing the gas-liquid contact area, guiding the airflow to form vortices and turbulence, and optimizing the gas-liquid mixing path, the porous baffle plate 521 significantly improves the treatment efficiency of the waste gas treatment device.

[0021] The system of the present invention may further include a control system for controlling the start-up and shut-down operations of the aforementioned motors and pumps, etc., to perform automatic operation of waste gas spraying treatment. It should be understood that the control system is not particularly limited and can be implemented using existing control technologies, which will not be elaborated upon here.

[0022] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
