[0002] Industrial emissions often have harmful effects on the environment and human health. Before being released into the atmosphere, they should be treated with purification measures to meet the requirements of emission standards. This process is called waste gas purification. Waste gas purification mainly refers to the treatment of industrial waste gases generated in industrial sites, such as particulate matter, flue gas, odorous gases, and toxic and harmful gases.

[0003] A search revealed numerous existing devices for treating waste gas. For instance, CN217939737U discloses a waste gas recirculation treatment tank, comprising a treatment tank with a curved pipe connected to its top. A fixed plate is fixedly installed on the side wall of the treatment tank, and a fixing hole is opened at the top of the fixed plate. A first motor is fixedly installed in the fixing hole, and a horizontal plate is fixedly sleeved on the output shaft of the first motor. A housing is fixedly installed on one side of the horizontal plate, and a connecting shaft is rotatably installed on the rear inner wall of the housing. A gear and a nozzle are fixedly sleeved on the outer side of the connecting shaft. A circular hole is opened on one side of the treatment tank. This invention has the following advantages and effects: Through the transmission of a worm gear and a worm wheel, and the cooperation of a gear and a rack, the operation of the second motor can drive the nozzle to swing back and forth, increasing the spraying range. By controlling the forward and reverse rotation of the first motor, the swinging nozzle can be driven to rotate in a circle, further increasing the spraying range and improving the waste gas treatment efficiency.

[0004] However, like most waste gas treatment patents, the aforementioned patents have the problem of not being able to recover and utilize the residual heat in the waste gas, resulting in the direct discharge of heat from the waste gas and a waste of resources.

[0005] Therefore, an integrated structure for waste gas recycling and treatment is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide an integrated structure for waste gas recycling and treatment, which can solve the problem that existing waste gas recycling tanks cannot recover and utilize the residual heat in the waste gas.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An integrated structure for waste gas recycling and treatment includes a treatment tank, a waste gas inlet pipe on the top of the treatment tank, a waste gas recovery and treatment mechanism inside the treatment tank, and a filter mechanism for easy maintenance on the side wall of the treatment tank.

[0009] The waste gas recovery and treatment mechanism includes a partition plate, a connecting plate, a liquid inlet pipe, a liquid outlet pipe, a filling pipe, a heat exchange pipe, and a liquid outlet filter assembly. The partition plate is fixedly connected to the middle of the treatment tank, the connecting plate is located at the top of the treatment tank, the liquid inlet pipe and the liquid outlet pipe are located on both sides of the treatment tank, and both the liquid inlet pipe and the liquid outlet pipe are located above the partition plate. The filling pipe is located on the side wall of the treatment tank and below the partition plate. Multiple heat exchange pipes pass through the partition plate and the connecting plate, and the liquid outlet filter assembly is located at the bottom of the treatment tank.

[0010] The filtration mechanism includes a connecting pipe, a filter tank, a support plate, a mounting cylinder, a filter element, an air outlet, an inspection cover, and an air outlet pipe. The connecting pipe is disposed on the side wall of the treatment tank and located below the partition plate. The filter tank is fixedly connected to one end of the connecting pipe. The two support plates are fixedly connected to the inner wall of the filter tank. Multiple mounting cylinders pass through the middle of the two support plates and extend to the outside of the filter tank. The filter element is disposed inside the mounting cylinder. Multiple air outlets are opened at one end of the mounting cylinder. The inspection cover is threaded to the exposed end of the mounting cylinder. The air outlet pipe is connected to the side wall of the filter tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This application incorporates a waste gas recovery and treatment mechanism. This process enables the recovery and utilization of heat in the waste gas during its transport and movement through heat transfer. Simultaneously, after the waste heat is recovered, the waste gas is discharged into a corresponding waste gas treatment liquid, allowing impurities in the waste gas to be adsorbed in the treatment liquid. This process also enables the adsorption and treatment of harmful substances in the waste gas, thus achieving waste heat recovery and adsorption filtration of the waste gas.

[0020] The present invention will be further explained below with reference to the accompanying drawings.

[0021] like Figure 1-5 As shown, an integrated structure for waste gas recycling and treatment includes a treatment tank 1, a waste gas inlet pipe 2 on the top of the treatment tank 1, a waste gas recycling and treatment mechanism 3 inside the treatment tank 1, and a filter mechanism 4 for easy maintenance on the side wall of the treatment tank 1.

[0022] The waste gas recovery and treatment mechanism 3 includes a partition plate 31, a connecting plate 32, a liquid inlet pipe 33, a liquid outlet pipe 34, a filling pipe 35, a heat exchange pipe 36, and a liquid discharge filter assembly 37. The partition plate 31 is fixedly connected to the middle of the treatment tank 1. The connecting plate 32 is located at the top of the treatment tank 1. The liquid inlet pipe 33 and the liquid outlet pipe 34 are located on both sides of the treatment tank 1, with the liquid inlet pipe 33 and the liquid outlet pipe 34 located above the partition plate 31. The filling pipe 35 is located on the side wall of the treatment tank 1 and below the partition plate 31. Multiple heat exchange pipes 36 are located in the middle of the partition plate 31 and the connecting plate 32. The liquid discharge filter assembly 37 is located at the bottom of the treatment tank 1.

[0023] Specifically, such as Figure 4 As shown, the drain filter assembly 37 includes a drain port 371, an outlet pipe 372, a bottom cover 373, and a filter screen 374. The drain port 371 is located at the bottom of the treatment tank 1, the outlet pipe 372 is located on the side wall of the drain port 371, the bottom cover 373 is threaded to the bottom of the drain port 371, and the filter screen 374 is located inside the drain port 371.

[0024] Specifically, such as Figure 4 As shown, a gas guide hood 6 is fixedly connected to the bottom of the exhaust gas pipe 2, and the bottom of the gas guide hood 6 is fixedly connected to the connecting plate 32.

[0025] Specifically, such as Figure 4As shown, a spiral blade 7 is fixedly connected to the inner wall of the heat exchange tube 36.

[0026] First, the treatment tank 1 is divided into upper and lower parts by the partition plate 31. The upper part of the treatment tank 1 is used for waste heat recovery treatment, and the lower part is used for adsorption and filtration treatment. The heat exchange liquid is delivered to the treatment tank 1 through the liquid filling pipe 33, and the waste gas treatment liquid is delivered to the bottom of the treatment tank 1 through the filling pipe 35. The waste gas is delivered to the treatment tank 1 through the waste gas connecting pipe 2 and the gas guide hood 6. Then the waste gas is diverted to multiple heat exchange pipes 36. During the transportation process, the waste gas heats the heat exchange liquid through the heat transfer effect. The spiral blade 7 can slow down the waste gas transportation speed and improve the waste heat recovery effect. Then the waste gas is delivered to the bottom of the treatment tank 1 and enters the waste gas treatment liquid. In this process, impurities in the waste gas are adsorbed and collected in the waste gas treatment liquid. At the same time, harmful substances in the waste gas are adsorbed and purified, realizing the waste heat recovery treatment of the waste gas while effectively filtering the waste gas.

[0027] Specifically, such as Figure 5 As shown, the filtration mechanism 4 includes a connecting pipe 41, a filter tank 42, a support plate 43, a mounting cylinder 44, a filter element 45, an air outlet 46, an inspection cover 47, and an air outlet pipe 48. The connecting pipe 41 is located on the side wall of the treatment tank 1 and above the partition plate 31. The filter tank 42 is fixedly connected to one end of the connecting pipe 41. Two support plates 43 are fixedly connected to the inner wall of the filter tank 42. Multiple mounting cylinders 44 are fixedly connected to the middle of the two support plates 43 and extend outward to the outside of the filter tank 42. The filter element 45 is located inside the mounting cylinder 44. Multiple air outlets 46 are opened at one end of the mounting cylinder 44. The inspection cover 47 is threaded to the exposed end of the mounting cylinder 44. The air outlet pipe 48 is located on the side wall of the support plate 43.

[0028] Specifically, such as Figure 5 As shown, multiple UV lamps 5 are installed on the inner wall of the vent pipe 48. The multiple UV lamps 5 are arranged at equal intervals and are powered by a battery embedded in the outer wall of the vent pipe 48.

[0029] Specifically, such as Figure 5 As shown, a protective cover 8 is provided at one end of the air outlet pipe 48, and multiple air vents 9 are provided on the side wall of the protective cover 8.

[0030] In use, the waste gas, after heat exchange and adsorption purification, enters the filter tank 42 through the connecting pipe 41. The filter elements 45 inside the multiple mounting cylinders 44 filter the waste gas, further refining the impurities. The filtered gas is discharged through the outlet 46. The inspection cover 47 facilitates the replacement and maintenance of the filter elements 45. The gas then exits through the outlet pipe 48. During this process, the UV lamp 5 decomposes and purifies the waste gas, thus providing auxiliary filtration of the waste gas after waste heat recovery and adsorption purification, improving the cleanliness of the treated waste gas. Furthermore, to ensure the waste gas can smoothly enter the filter tank 42, a gas delivery pump can be installed at the end of the outlet pipe 48. Care should be taken to control the power of the gas delivery pump to avoid drawing the waste gas adsorption liquid into the filter tank 42.

[0031] By adopting the above technical solution, the problem that the existing waste gas circulation treatment tank 1 cannot recover and utilize the waste heat in the waste gas is solved. Existing waste gas treatment devices usually use filtration, purification and disinfection lamp links, but do not recover and reuse the waste heat in the waste gas. The heat in the waste gas is directly discharged, resulting in a waste of resources.
