[0002] Acid mist generation is a common problem in chemical production processes. Acid mist not only causes serious pollution to the production environment and affects the health of workers, but also has an adverse impact on the surrounding ecological environment. Existing chemical acid mist cooling and purification towers can cool and purify acid mist to a certain extent, but there are still many shortcomings in terms of treatment effect. Therefore, we have developed a new type of chemical acid mist cooling and purification tower.

[0003] The existing technology still has the following drawbacks in its use: Existing chemical acid mist cooling and purification towers suffer from problems such as uneven airflow distribution and low treatment efficiency, making it difficult to meet the environmental protection and high efficiency requirements of modern chemical production. In addition, some existing purification towers also have disadvantages such as complex operation and difficult maintenance, which increases the operating costs and difficulties of enterprises. Existing chemical acid mist cooling and purification towers also need improvement in terms of cooling function. The cooling efficiency of the cooling device is not high, and it cannot quickly and effectively reduce the temperature of acid mist to the ideal range, which affects the subsequent purification effect and makes the overall treatment efficiency fail to meet the expected standard.

[0004] In view of this, we propose a chemical acid mist cooling and purification tower to solve the existing problems. Utility Model Content

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1 - Figure 5 As shown, the present invention proposes a chemical acid mist cooling and purification tower, including a top cover 1, a tank 2, a base 3, and a diffusion assembly 4. The top cover 1 is fixedly installed on the top of the tank 2, and an exhaust pipe 101 is fixedly installed on the top of the top cover 1. A liquid level sensor 102 is fixedly installed at the bottom of the top cover 1. The liquid level sensor 102 is of type M7R. The top cover 1 can cooperate with the tank 2 to form a closed environment, so as to mix the acid mist with the treatment liquid and achieve the purification of the acid mist gas. The exhaust pipe 101 can discharge the purified air from the top of the purification tower. The liquid level sensor 102 can monitor the liquid level inside the tank 2 in real time, thereby judging the amount of liquid accumulation inside the tank 2. When there is a large amount of liquid accumulation inside the tank 2, the liquid can be discharged in time through the three-way pipe 302 to avoid affecting the subsequent use of the purification tower. A base 3 is fixedly installed at the bottom of the tank 2, and a bracket 301 is fixedly installed around the bottom of the base 3. A three-way pipe 302 is fixedly installed at the bottom of the base 3, and an aeration disc 303 is fixedly installed at the top of the base 3. Several spray pipes 304 are fixedly installed near the edge of the top of the aeration disc 303. The aeration disc 303 is made of stainless steel, which has good corrosion resistance and can adapt to the harsh environment of chemical acid mist. The spray pipes 304 are evenly distributed on the top edge of the aeration disc 303, which can evenly spray the treatment liquid into the inside of the tank 2, fully contact the acid mist, and improve the purification effect. A control panel 204 is fixedly installed on the front of the tank body 2, and guide channels 202 are fixedly installed on both sides of the tank body 2. The guide channels 202 are C-shaped metal structures that run from front to back. A blower 203 is fixedly installed at the front or back opening of the guide channels 202. A water inlet pipe 201 is fixedly installed on one side of the tank body 2 near the top. One end of the water inlet pipe 201 extends into the interior of the tank body 2 and a guide ring 206 is fixedly installed thereon. Several nozzles 205 are fixedly installed at the bottom of the guide ring 206. The control panel 204 can display real-time information. The display tank 2 shows key parameters such as temperature, liquid level, and purification progress inside, facilitating monitoring and operation by staff. The special design of the guide channel 202 guides external cold air into the tank, while the fan 203 accelerates airflow, forming an effective cooling airflow that exchanges heat with the acid mist inside the tank 2, reducing the acid mist temperature. The water inlet pipe 201 is used to inject treatment liquid into the tank 2. The design of the guide ring 206 and the nozzle 205 allows the treatment liquid to be sprayed evenly inside the tank 2, fully mixing with the acid mist and improving purification efficiency. Several sets of diffusion components 4 are fixedly installed on the inner wall of the tank body 2. The diffusion components 4 are firmly connected to the inner wall of the tank body 2 through the shaft frame 401. The rotating shaft in the shaft frame 401 can rotate flexibly. When acid mist enters the tank body 2, the airflow impacts the fan blade 402, causing the fan blade 402 to rotate around the rotating shaft, thereby consuming the energy of the acid mist gas, slowing down the flow rate of the acid mist gas, prolonging the contact time between the acid mist and the treatment liquid, and improving the purification efficiency of the purification tower. At the same time, the rotation of the fan blade 402 can increase the contact area between the acid mist and the treatment liquid, further improving the purification effect of the treatment liquid on the acid mist.

[0019] Furthermore, the diffusion assembly 4 includes a shaft frame 401, which is fixedly connected to the inner wall of the tank 2. A rotating shaft is provided inside the shaft frame 401. The shaft frame 401 is made of high-strength alloy material, which has good corrosion resistance and mechanical strength and can withstand long-term use in acid mist environment without damage. The rotating shaft is connected to the shaft frame 401 through a precision bearing to ensure flexible and stable rotation, reduce frictional resistance during rotation, and reduce energy loss.

[0020] Furthermore, several sets of fan blades 402 are fixedly installed on the outer side of the shaft frame 401. The fan blades 402 are arc-shaped plates, and several ventilation holes 403 are opened inside the fan blades 402. The arc design of the fan blades 402 can better follow the airflow direction, making the acid mist pass through more smoothly. The ventilation holes 403 further optimize the airflow, so that the acid mist can be evenly distributed around the fan blades 402, forming a stable airflow field and improving the purification effect.

[0021] Furthermore, the radial direction of the vent 403 is not perpendicular to the surface of the fan blade 402, and the inner side of the fan blade 402 is on the same longitudinal axis as the nozzle 304.

[0022] Furthermore, the liquid level sensor 102 is located near the bottom opening of the exhaust pipe 101, and the liquid level sensor 102 and the nozzle 304 are not on the same longitudinal axis.

[0023] Furthermore, a valve is fixedly installed inside the water inlet pipe 201, and the nozzle 205 is installed at an angle to the bottom of the guide ring 206. The side of the guide ring 206 away from the water inlet pipe 201 is fixedly connected to the inner wall of the tank 2. The valve can precisely control the injection volume of the treatment liquid and adjust the flow rate according to actual needs to ensure the stability of the concentration of the treatment liquid inside the purification tower. The angled installation of the nozzle 205 allows the treatment liquid to be sprayed out at a certain angle, which can cover a larger area and make more sufficient contact with the acid mist.

[0024] Furthermore, valves are fixedly installed at all three openings of the three-way pipe 302, and the top of the three-way pipe 302 is fixedly connected to the bottom of the aeration disc 303. By controlling the valves at different openings, the discharge direction and flow rate of the accumulated liquid can be flexibly adjusted to meet the usage requirements under different conditions. The stable connection between the three-way pipe 302 and the aeration disc 303 ensures that the treated liquid can be smoothly sprayed out from the aeration disc 303, forming a uniform droplet distribution and improving purification efficiency.

[0025] Working principle: The entire equipment is controlled by the control panel 204. When the chemical acid mist enters the tank 2, it is first sprayed upwards evenly through the aeration disc 303 and the spray pipe 304, and then comes into contact with several sets of diffusion components 4. The fan blades 402 and the vent holes 403 guide the acid mist to form a uniform airflow distribution. At the same time, the blower 203 starts to introduce external cold air into the guide channel 202 to cool the tank 2. The treatment liquid enters the guide ring 206 through the water inlet pipe 201, and then is evenly sprayed inside the tank 2 through the nozzle 205 to fully contact the acid mist for purification. The treated gas is discharged through the exhaust pipe 101 on the top cover 1. The liquid level sensor 102 monitors the liquid level inside the tank 2 in real time to ensure the safe operation of the equipment.

[0026] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
