Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a high-efficiency waste gas treatment spray tower. Background Art

[0002] With the acceleration of industrialization, the problem of waste gas generated in the industrial production process is becoming increasingly serious. These waste gases contain a large amount of harmful substances. If they are directly discharged into the atmosphere without effective treatment, they will cause great harm to the environment and human health. Therefore, the development and application of waste gas treatment technology is particularly important. As a common waste gas treatment equipment, the waste gas treatment spray tower works by contacting the waste gas with the spray liquid and removing pollutants in the waste gas by chemical or physical absorption.

[0003] However, the existing waste gas treatment spray tower has some shortcomings. First, the traditional straight-cylindrical waste gas guide channel design makes the waste gas in the center area not in sufficient contact with the spray liquid, resulting in low absorption efficiency. Second, the distribution of the spray liquid is often not uniform, especially at the top and bottom of the spray tower, the coverage area of ​​the spray liquid is limited, affecting the waste gas treatment effect.

[0004] Therefore, this invention proposes a high-efficiency waste gas treatment spray tower to solve the above problems. Utility Model Content

[0005] In order to overcome the defects of the prior art, the utility model aims to provide a high-efficiency waste gas treatment spray tower.

[0006] To achieve the above object, the technical solution of the utility model is implemented as follows: an efficient waste gas treatment spray tower, comprising a treatment tank, a long cylindrical liquid storage tank is arranged in the center of the treatment tank, a liquid storage tank bracket supported on the bottom of the treatment tank is arranged at the bottom of the liquid storage tank, a vertically distributed annular air guide channel is formed between the outer wall of the liquid storage tank and the inner wall of the treatment tank, and a rotating spray mechanism is also installed inside the liquid storage tank;

[0007] The rotary spraying mechanism specifically includes the following structure:

[0008] A reduction motor distributed on the top of the processing tank;

[0009] A liquid pump connected to the output end at the bottom of the reduction motor;

[0010] Spray pipes connected to the four liquid outlet ends of the liquid pump, each of which is arranged in a 7-shape and has a bent end that fits the inner wall of the treatment tank;

[0012] Preferably, a conical air inlet hopper is provided at the bottom center of the processing tank.

[0013] Preferably, an exhaust gas intake pipe communicating with the interior of the conical air intake hopper is installed at the bottom of the outer side of the treatment tank.

[0014] Preferably, a conical gas outlet hopper is installed at the top of the processing tank.

[0015] Preferably, side mounting frames are installed on the front, rear, left and right side walls of the reduction motor, and one outer end of the side mounting frame is butted against the side wall of the processing tank near the top.

[0016] Preferably, a liquid inlet valve pipe is installed on the tank wall at the bottom end on the left side of the liquid storage tank.

[0017] Preferably, a spray waste liquid outlet pipe is installed on the left side of the bottom of the processing tank.

[0018] Preferably, the bottom of the processing tank is supported on the ground by an external bracket.

[0019] The beneficial effects of the utility model are embodied in:

[0020] Improve the efficiency of waste gas treatment: The high-efficiency waste gas treatment spray tower ensures that the waste gas can be evenly contacted with the spray liquid through the design of the annular air guide channel, avoiding the problem that the waste gas near the center of the traditional straight-cylindrical waste gas guide channel cannot fully contact with the spray liquid directly, thereby improving the absorption efficiency.

[0021] Optimize the distribution of spray liquid: The design of the rotating spray mechanism, especially the 7-shaped spray pipe, enables the spray liquid to completely cover the entire annular channel through which the exhaust gas passes from top to bottom during its rotation, ensuring that the exhaust gas can be fully in contact with the spray liquid during the conveying process, thereby enhancing the exhaust gas treatment effect.

[0022] Optimization of exhaust gas guidance and emission: The design of the conical air inlet hopper and the conical air outlet hopper helps to concentrate the exhaust gas into the bottom center of the treatment tank and discharge the treated exhaust gas in a centralized manner, respectively, optimizing the exhaust gas guidance and emission process.

[0023] In summary, the high-efficiency waste gas treatment spray tower not only improves the efficiency and effect of waste gas treatment through its innovative design and optimized workflow, but also ensures the stable operation and convenience of maintenance of the equipment. The design of its annular air guide channel and rotating spray mechanism ensures full contact between the waste gas and the spray liquid, effectively improving the absorption efficiency of pollutants in the waste gas. In addition, the introduction of the conical air inlet and outlet hoppers optimizes the guidance and discharge of the waste gas, making the entire treatment process more efficient and environmentally friendly.

[0036] In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0037] Please refer to the instruction manual Figure 1-Figure 4 , the utility model provides a high-efficiency waste gas treatment spray tower:

[0038] The high-efficiency waste gas treatment spray tower is mainly composed of a treatment tank 1, and a long cylindrical liquid storage tank 5 is arranged in the center of the treatment tank 1. The liquid storage tank 5 is used to store spray liquid, and is arranged in a long cylindrical shape. A rotating spray mechanism 6 is installed inside the treatment tank 1.

[0039] A vertically distributed annular air guide channel is formed between the outer wall of the liquid storage tank 5 and the inner wall of the treatment tank 1, and the channel is used for the rise and treatment of the exhaust gas. The design of the annular air guide channel ensures that the exhaust gas can be evenly contacted with the spray liquid, improves the absorption efficiency, avoids the exhaust gas near the center of the traditional straight-cylindrical exhaust gas guide channel from being unable to fully contact the spray liquid directly, and ensures that the exhaust gas and the spray liquid are fully in contact.

[0040] A rotary spray mechanism 6 is installed inside the liquid storage tank 5, and the mechanism includes the following structure:

[0041] The reduction motor 61 located at the top of the treatment tank 1 is used to drive the rotation of the liquid pump 62 and the spray pipe 63 to achieve uniform distribution and coverage of the spray liquid;

[0042] The output end at the bottom of the reduction motor 61 is connected to a liquid pump 62, which is responsible for pumping the spray liquid in the liquid storage tank 5 to the spray pipe 63;

[0043] The four liquid outlet ends of the liquid pump 62 are connected to the spray pipes 63, each of which is in a 7-shape, and the bent end is attached to the inner wall of the treatment tank 1. This design allows the liquid sprayed by the rotating four spray pipes 63 to completely cover the entire annular channel through which the exhaust gas passes from top to bottom, ensuring that the exhaust gas can be fully in contact with the spray liquid during the conveying process;

[0044] The liquid extraction end of the liquid extraction pump 62 is connected to a liquid extraction pipe 64 , and the bottom end of the liquid extraction pipe 64 is connected to the bottom of the liquid storage tank 5 , so as to ensure that the spray liquid can be effectively extracted and transported to the spray pipe 63 .

[0045] A conical air inlet hopper 3 is provided at the bottom center of the treatment tank 1 to guide the exhaust gas into the treatment tank 1. The design of the conical air inlet hopper 3 helps to concentrate the exhaust gas into the bottom center of the treatment tank, and then pass through the bottom end of the liquid storage tank 5 to be evenly dispersed into the annular air guide channel.

[0046] An exhaust gas inlet pipe 2 communicating with the inside of the conical air inlet hopper 3 is installed at the bottom of the outer side of the treatment tank 1 to introduce the exhaust gas into the treatment tank 1. The position and connection method of the exhaust gas inlet pipe 2 ensure that the exhaust gas can smoothly enter the treatment tank 1 and be fully mixed with the spray liquid.

[0047] A conical outlet hopper 4 is installed at the top of the treatment tank 1 for discharging the treated waste gas. The design of the conical outlet hopper 4 helps to discharge the treated waste gas in a centralized manner.

[0048] Side mounting frames 7 are installed on the front, rear, left and right side walls of the reduction motor 61, and one end of the outer side mounting frame 7 is docked on the side wall of the processing tank 1 near the top to fix the reduction motor 61. The design of the side mounting frame 7 provides a stable support to ensure the stability of the reduction motor 61 during operation.

[0049] A liquid inlet valve pipe 51 is installed on the tank wall at the bottom end of the left side of the liquid storage tank 5 for replenishing the spray liquid.

[0050] A spray waste liquid outlet pipe 11 is installed on the left side of the bottom of the treatment tank 1 to collect the treated waste liquid. The location design of the spray waste liquid outlet pipe 11 allows the waste liquid to be discharged smoothly to avoid accumulation in the treatment tank 1 and affect the treatment effect.

[0051] The bottom of the treatment tank 1 is supported on the ground by an external support 12 to ensure the stability of the spray tower.

[0052] How it works

[0053] Exhaust gas introduction: Exhaust gas enters the treatment tank 1 through the exhaust gas inlet pipe 2, and is concentratedly introduced into the bottom center of the treatment tank through the design of the conical air inlet hopper 3.

[0054] Exhaust gas distribution: The exhaust gas is evenly dispersed from the bottom of the liquid storage tank 5 to the inside of the annular air guide channel. The design of the annular air guide channel ensures that the exhaust gas can rise evenly.

[0055] Extraction and spraying of spray liquid: The reduction motor 61 drives the liquid extraction pump 62 to rotate and work. The liquid extraction pump extracts the spray liquid from the bottom of the liquid storage tank 5 through the liquid extraction pipe 64, and rotates and evenly sprays the spray liquid into the annular air guide channel through the spray pipe 63 connected to the four liquid outlet ends.

[0056] Contact between waste gas and spray liquid: waste gas fully contacts with spray liquid during the rising process, and spray liquid absorbs pollutants in waste gas to improve absorption efficiency.

[0057] Exhaust gas is discharged after treatment: the treated exhaust gas is discharged from the treatment tank 1 through the conical exhaust hopper 4.
