The packing layer includes a packing support plate and a waist-shaped packing frame. The packing support plate is a grid plate, and a waist-shaped packing frame is provided on the packing support plate. The waist-shaped packing frame is provided with packing A, and the waist-shaped packing frame and the spray tower body bracket are filled with packing B; the air outlet pipe is connected to a high-efficiency filter box, and the high-efficiency filter box is connected to the chimney through a fan.

[0004] The above application documents achieve corresponding purification of exhaust gas through the setting of various structures. However, the exhaust gas generally needs to be injected into the clean water at the bottom of the inner side of the spray tower to absorb the waste in the exhaust gas and achieve purification. At the same time, a circulation structure is also provided to achieve circulating spraying from the top side, but no liquid treatment mechanism is provided, which affects the subsequent purification effect of the exhaust gas. In addition, the method of purifying the exhaust gas separately by the adsorption layer and the spray layer in the spray tower also needs to be improved.

[0005] Therefore, we proposed an environmentally friendly exhaust gas treatment tower with multiple purification functions. Summary of the invention

[0006] In view of the deficiencies of the prior art, the present invention provides an environmentally friendly waste gas treatment tower with multiple purification functions, which solves the problem that the existing circulating liquid flow is not purified and is directly used for subsequent waste gas treatment with poor effect.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: an environmentally friendly waste gas treatment tower with multiple purification functions, comprising a tower base and a tower body at the top thereof, wherein the tower body is provided with an air guide frame, a first purification frame, a group of humidification frames, a second purification frame, another group of humidification frames, an air guide frame and a spray frame in sequence from bottom to top, a bucket is fixedly installed on the top of the spray frame, an L-shaped exhaust pipe is fixedly connected to the top of the bucket, and an activated carbon adsorption mesh layer for preliminary purification of the waste gas is fixedly installed in the air guide frame;

[0008] The tower base is composed of an upper tower ring, a purification frame and a base. The tower base is filled with liquid. An activated carbon filler layer is fixedly installed on the inner side of the purification frame. A liquid guide pipe is fixedly connected to the right side of the base. The base is fixedly connected to a circulation mechanism through the liquid guide pipe, and the tower base is connected to the spray frame in the tower body through the circulation mechanism.

[0009] A side pipe in a side U shape and connected with the upper tower ring and the base is arranged on the left side of the base, and an auxiliary pump body is fixedly installed in the side pipe.

[0010] As a preferred solution of the environmentally friendly waste gas treatment tower with multiple purification functions described in the present invention, the main body of the circulation mechanism is a circulation pipe, the bottom end of the circulation pipe is fixedly connected to the outer end of the liquid guide pipe, the top end of the circulation pipe is fixedly connected to the input end of the spray frame, and the main pump body is fixedly installed on the circulation pipe;

[0011] Among them, the setting of the circulation mechanism structure facilitates the upward transportation of the purified liquid output from the bottom side of the tower base to the inside of the spray frame, thereby achieving the effect of purifying the liquid flow, and assisting the spray components inside the spray frame to efficiently spray downward on the inside of the tower body, ensuring the purification effect of the exhaust gas, and solving the problem that the existing circulating liquid flow is not purified before subsequent spraying of the exhaust gas processing, resulting in its purification effect needs to be improved.

[0012] As a preferred solution of the environmentally friendly waste gas treatment tower with multiple purification functions of the present invention, the circulation pipe is provided with three groups of lateral branch pipes, the outer end of the topmost branch pipe is fixedly connected to the input end of the spray frame, and the outer ends of the two groups of branch pipes below it are respectively connected to the input ends of the two groups of humidification frames;

[0013] Among them, the arrangement of three groups of output ends of the circulation mechanism can respectively transport the purified liquid flow to the spray frame and two groups of humidification frames, and the spray frame performs efficient spray purification, while the remaining two groups of output ends can transport the purified liquid flow to the two groups of humidification frames, which input the purified liquid flow into the first purification frame and the second purification frame to immerse it in the gap between the fillers, thereby being able to efficiently purify the exhaust gas passing through. The existing liquid flow in the first purification frame and the second purification frame is a post-spray liquid flow. Firstly, the liquid flow is not purified accordingly, and secondly, the spraying volume is small, resulting in a small amount of liquid flow filled in the filler grooves in the first purification frame and the second purification frame, thereby affecting the subsequent exhaust gas purification effect.

[0014] As a preferred solution of the environmentally friendly waste gas treatment tower with multiple purification functions of the present invention, a waste gas packing layer is fixedly installed on the inner side of the first purification frame, a demisting packing layer is fixedly installed on the inner side of the second purification frame, and a humidification frame is fixedly installed on the top of the first purification frame and the second purification frame;

[0015] Among them, the setting of the exhaust gas packing layer, the packing layer is usually composed of multiple layers of packing, these packings have a large specific surface area and good adsorption performance, the material, shape and size design of the packing are carefully selected and calculated to ensure that it can fully contact with the exhaust gas and effectively absorb harmful substances in the exhaust gas. Common packing structures include sheet, ring, spherical and spiral forms. Sheet packing has a simple structure and is easy to clean, but the treatment effect is poor; ring and spherical packings are more commonly used, with various shapes, large surface areas, easy to stack, and conducive to full contact between exhaust gas and packing; spiral packing is a new type of packing that has appeared in recent years, with the characteristics of compact structure, large volume ratio, and uniform gas-liquid distribution;

[0016] Among them, the setting of the waste gas packing layer can increase the gas-liquid contact area: the porosity and structure of the packing layer make the waste gas produce more liquid film or gas film on the surface of the packing, thereby increasing the contact area between the waste gas and the packing, and promoting the adsorption and decomposition of pollutants. Secondly, it provides a reaction site: the surface of the packing layer usually has a certain roughness and pore structure, which provides a good place for the chemical reaction between the waste gas and the spray liquid, and helps the harmful substances in the waste gas to be converted into harmless or low-toxic substances. Secondly, it promotes the uniform distribution of waste gas: the design of the packing layer helps to make the waste gas evenly distributed in the spray tower, avoid the occurrence of local concentrations that are too high or too low, and ensure the uniformity and stability of waste gas treatment. Finally, it slows down the waste gas flow rate: when the waste gas passes through the packing layer, the flow rate will be slowed down to a certain extent, which is conducive to the full contact and reaction between the waste gas and the spray liquid, and also helps to reduce the impact and wear of the waste gas on the spray tower, and extend the service life of the equipment;

[0017] The defogger filler layer is usually made of porous materials, such as sponge, ceramics and plastics. Sponge materials are suitable for high humidity and high temperature environments, ceramic materials have high corrosion resistance and high temperature performance, and plastic materials have good corrosion resistance and high temperature resistance. The shape and size of the filler will also affect the efficiency and performance of the defogger. Common filler shapes include spherical, annular, skeleton and spiral shapes.

[0018] The main function of the demisting packing layer is to increase the efficiency and performance of the demisting device. The packing layer, through its porous structure, allows water vapor to gradually condense into water droplets, which are deposited on the surface of the packing and eventually fall into the water collection tank at the bottom by gravity, thereby removing water mist from the gas.

[0019] As a preferred solution of the environmentally friendly waste gas treatment tower with multiple purification functions described in the present invention, a liquid pan is fixedly installed on the inner side of the humidifying frame, and five groups of gas grooves distributed in an annular shape are opened on the liquid pan. The inner side of the liquid pan is cavity-shaped, and a filling liquid hole is opened at the bottom of the liquid pan. The top of the liquid pan is fixedly connected to a branch pipe, and the outer end of the branch pipe is fixedly connected to a first external pipe, and the humidifying frame is connected to the output end of the circulation mechanism through the first external pipe;

[0020] Among them, the setting of the humidification frame structure is convenient for evenly dividing the liquid flow output by the circulation mechanism and conveying it to the inner side of the exhaust gas filling layer and the demisting filling layer, so that the purified liquid flow fills the gaps in the filling, thereby being able to efficiently purify the exhaust gas passing through.

[0021] As a preferred solution of the environmentally friendly waste gas treatment tower with multiple purification functions of the present invention, a driving motor is fixedly installed on the outer wall of the spray frame, the output end of the driving motor passes through the spray frame and is fixedly sleeved with a gear disk located inside thereof, and a spray assembly meshed with the gear disk is arranged on the inner side of the tower body;

[0022] Among them, the setting of the driving motor can drive the rotation of the gear disk, thereby driving the spray assembly, so that the ring frame therein rotates on the sliding frame, thereby achieving the effect of uniform spraying and simultaneously achieving the effect of efficient purification of exhaust gas.

The second external pipe is fixedly connected to the input end of the spray assembly through the bearing ring, and the outer end of the second external pipe is fixedly connected to the output end at the top of the circulation mechanism;

[0024] Among them, the setting of the bearing ring facilitates the free rotation of the ring frame in the spray assembly at the inner end of the second external pipe, ensuring the subsequent spraying effect driven by the drive motor.

[0025] As a preferred solution of the environmentally friendly waste gas treatment tower with multiple purification functions of the present invention, the spray assembly includes a sliding frame fixedly welded on the inner wall of the spray frame, and an L-shaped annular groove is provided at the upper edge of the inner side of the sliding frame;

[0026] The inner side walls of the inner ring groove of the sliding frame are all set to be smooth.

[0027] As a preferred solution of the environmentally friendly waste gas treatment tower with multiple purification functions described in the present invention, the spray assembly also includes a ring frame arranged on the top side of the sliding frame, the ring frame is an L-shaped ring adapted to the specifications of the ring groove inside the sliding frame, the ring frame is rotatably sleeved on the inner side of the sliding frame, and a ring gear is fixedly installed on the top of the ring frame and is meshed with the bottom side of the toothed disc in an annular shape;

[0028] The L-shaped ring of the ring frame is arranged to facilitate its sliding and rotating sleeve in the ring groove of the inner wall of the slide frame, thereby ensuring its stability after assembly.

[0029] As a preferred solution of the environmentally friendly waste gas treatment tower with multiple purification functions described in the present invention, the ring frame is provided with a spray plate, and ten groups of spray pipes distributed in an annular manner are fixedly welded at the output end of the spray plate, and a cavity is provided in the spray plate. The input end at the center of the top of the spray plate is fixedly connected to the inner end of the second external pipe, and five groups of high-pressure nozzles distributed linearly are fixedly installed at the bottom of each group of spray pipes;

[0030] Among them, the setting of the spray plate can evenly transport the purified liquid flow to the inner side of the spray pipe, and output the spray liquid from the high-pressure nozzle on the bottom side, thereby increasing the contact area between it and the exhaust gas, thereby ensuring the purification effect of the exhaust gas.

[0031] The present invention provides an environmentally friendly waste gas treatment tower with multiple purification functions. It has the following beneficial effects:

[0032] 1. The environmentally friendly waste gas treatment tower with multiple purification functions can directly inject the waste gas output by the upper tower ring and the air guide seat into the liquid flow through the arrangement of the inner structure of the tower base, so as to directly purify the waste gas. The purified liquid flow passes through the activated carbon filler layer in the purification frame, so that the liquid flow is efficiently purified. The purified liquid flow enters the base and cooperates with the circulation mechanism to provide the purified liquid to the humidification frame and the spray frame, thereby ensuring the subsequent purification effect of the waste gas, and solving the problem that the existing circulating liquid flow is not purified and directly performs the subsequent waste gas treatment with poor effect.

Finally, the exhaust pipe 4 at the top of the bucket tube 27 outputs the purified exhaust gas, thereby achieving the effect of efficient purification of the exhaust gas. The liquid flow after contacting the exhaust gas gradually flows downward and re-enters the tower base 1, and is then purified by the activated carbon filling layer 19 on the inner side of the tower base 1, thereby achieving the effect of liquid flow circulation, ensuring efficient purification of the exhaust gas.
