Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, and specifically relates to a multi-channel waste gas adsorption treatment device. Background Technology

[0002] Industrial waste gases from chemical, pharmaceutical, and coating industries are complex in composition. In addition to conventional volatile organic compounds such as toluene and xylene, they also contain room-temperature polymerizable substances such as styrene, acrylic acid, and methyl methacrylate. When these room-temperature polymerizable substances are transported through pipelines, they are triggered to polymerize by temperature fluctuations and trace impurities, forming solid particles or viscous substances. These particles clog the pores of the adsorption materials, reducing the effective adsorption area of ​​the adsorption materials. This not only significantly shortens the service life of the adsorption materials and increases the frequency of replacement and maintenance costs, but may also cause local "short circuits" due to uneven airflow distribution, further reducing the overall treatment efficiency.

[0003] After searching, the existing technology public account: CN222445912U A multi-channel high-efficiency biological purification waste gas device includes a treatment tank assembly. The top surface of the treatment tank assembly is provided with a sealing tank cover, and the treatment tank assembly and the sealing tank cover are fixedly installed by bolts.

[0004] Further search revealed that the existing technology announcement number CN222019230U describes a multi-channel waste gas adsorption device for easy feeding, comprising a housing with an adsorption chamber inside. The adsorption chamber contains multiple vertically arranged adsorption channels, and partitions spaced apart divide the chamber into multiple layers. The partitions of adjacent layers are staggered. A storage chamber is located above the adsorption chamber, connected to the top opening of the adsorption channels. A push rod is located above the storage chamber, with one end fixedly connected to a horizontally arranged electric telescopic rod. The other end of the electric telescopic rod is connected to the side wall of the storage chamber. The electric telescopic rod and the push rod are vertically arranged in the horizontal direction, with the central axis of the electric telescopic rod perpendicular to the long axis of the push rod.

[0005] None of the above comparative documents pre-treated the exhaust gas before it entered the device, which failed to solve the problem of room-temperature polymerizable substances clogging the pores of the adsorption material, reducing the effective adsorption area of ​​the adsorption material, shortening the service life of the adsorption material, and increasing the replacement frequency. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-channel waste gas adsorption treatment device, which achieves efficient cleaning of polymerizable substances in waste gas at room temperature, increases the service life of the adsorption material, and reduces the replacement frequency of the adsorption material.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The spray mixing mechanism is installed inside the washing chamber.

[0009] The top of the processing chamber is provided with an inspection port, which is located at the top of the multi-channel adsorption chamber.

[0010] The filter chamber is equipped with several sets of filter racks, on which filter plates are fixedly installed. The filter racks are inserted into the filter chamber, and the top of the filter rack passes through the top of the filter chamber and the top of the treatment chamber in sequence. The top of the filter rack is equipped with a lifting ring, and sealing strips are provided at the connection between the filter rack and the filter chamber and the treatment chamber.

[0011] Each channel of the multi-channel adsorption chamber is filled with adsorption material, which is activated carbon.

[0012] The bottom of the processing chamber is equipped with a drain outlet, which is located at the bottom of the washing chamber and is connected to the washing chamber.

[0013] The spray mixing mechanism includes a geared motor, a rotating shaft I, a fixed plate, a stirring plate, and a rotating shaft II. The washing chamber is fixedly installed inside one side of the treatment chamber and is connected to the filter chamber. The fixed plate is fixedly installed inside one side of the filter chamber. One end of the rotating shaft I passes through the treatment chamber and one side of the washing chamber and is rotatably connected to the fixed plate. The washing chamber has a spiral channel, the outer wall of which fits against the inner wall of the washing chamber. The rotating shaft I is located in the middle of the spiral channel and is fixedly connected to it. The geared motor is installed on the top of the treatment chamber, and the output shaft of the geared motor has a synchronous pulley connected to one end of the rotating shaft I via a synchronous belt. The transmission connection includes a hollow rotating shaft I and a rotating shaft II rotatably mounted inside the rotating shaft I. A motor is located at one end of the rotating shaft II, and the motor output shaft is fixedly connected to the rotating shaft II via a coupling. A motor compartment is located outside the motor, and the motor compartment is fixedly connected to the rotating shaft I via bolts and nuts.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1) The atomizing nozzle atomizes and sprays the detergent. The geared motor drives the rotating shaft I to rotate via the synchronous belt. The rotating spiral channel guides the exhaust gas to flow along the spiral path, increasing the contact area between the detergent and the exhaust gas while extending the contact time between the exhaust gas and the atomized detergent. The motor drives the rotating shaft II to rotate, which in turn drives the stirring plate to rotate. The stirring plate agitates the exhaust gas and detergent droplets, accelerating the mixing speed of the exhaust gas and detergent droplets. This significantly reduces the polymerizable substances and particulate impurities in the exhaust gas, greatly reducing the filtration burden of the subsequent filter chamber and the adsorption pressure of the multi-channel adsorption chamber. It effectively prevents the pores of the adsorption material from being blocked, significantly extends the service life of the adsorption material, and reduces the frequency of adsorption material replacement.

[0017] 2) The reserved maintenance port on the top of the multi-channel adsorption chamber and the plug-in design of the filter frame facilitate the replacement of adsorption materials and filter screens in the multi-channel adsorption chamber, reduce the difficulty of disassembling the device, significantly shorten the maintenance time, and reduce operation and maintenance costs.

Several sets of bevel gears are provided on rotating shaft II 210. Several sets of connecting plates 26 are provided between the side walls of spiral channel 23. Stirring plate 25 is rotatably connected to connecting plate 26. One end of stirring plate 25 is located inside rotating shaft I 22 and is equipped with bevel gear. The bevel gear at one end of stirring plate 25 meshes with the bevel gear on rotating shaft II 210.

[0036] Water pipes 28 are provided on both sides of the rotating shaft II 210. The water pipes 28 are fixedly installed inside the rotating shaft I 22. Several sets of atomizing nozzles 29 are provided on one side of the water pipes 28. The water outlet of the atomizing nozzles 29 is located outside the rotating shaft I 22.

The rotating sleeve meets the detergent supply during the rotation of the diversion pipe.

[0037] As described above, after the industrial waste gas enters the washing chamber 103, the detergent flows into the water pipe 28 through the rotating sleeve 214 and the diversion pipe 213, and then is atomized and sprayed out through multiple sets of atomizing nozzles 29. The reduction motor 21 drives the rotating shaft I 22 to rotate through the synchronous belt. The spiral channel 23 rotates to guide the waste gas to flow along the spiral path, prolonging the contact time with the atomized detergent.
