[0002] Waste gas treatment for spraying refers to a series of technical measures and processes for purifying various waste gases generated during spraying operations to meet relevant national emission standards or subsequent reuse requirements. In spraying, organic solvents evaporate during paint spraying, forming waste gas containing volatile organic compounds (VOCs), and may also be accompanied by pollutants such as paint mist particles.

[0025] Based on the existing concerns about the harmful effects of gases generated during the spraying process on human health, please refer to [link / reference]. Figures 1-4 This utility model provides a technical solution: a waste gas treatment device for spraying processing, including a treatment chamber 1, an air inlet pipe 2 fixedly installed at the right end of the treatment chamber 1, a chamber door 3 hinged to the front of the treatment chamber 1, a spraying mechanism 4 installed above the treatment chamber 1, and a treatment mechanism 5 installed on the left side of the treatment chamber 1.

[0027] The processing mechanism 5 includes a processing section and a fixing section.

[0028] The connecting part includes a fixing frame 41, the outer side of the fixing frame 41 is fixedly connected to the inner wall of the processing chamber 1, and a connecting groove is opened inside the fixing frame 41, and a screen 42 is fixedly installed inside the connecting groove.

[0029] The spraying unit includes a water pump 44, and a connecting chamber 43 is fixedly installed in front of the water pump 44. The connecting chamber 43 is located directly below the treatment chamber 1. The upper end of the connecting chamber 43 is fixedly connected to the lower end of the treatment chamber 1, and the connecting chamber 43 and the treatment chamber 1 are interconnected.

[0030] A water pipe 45 is provided at the rear of the treatment chamber 1. The lower end of the water pipe 45 is fixedly connected to the water pump 44, and a connecting seat 46 is fixedly provided at the upper end of the water pipe 45. The lower end of the connecting seat 46 is fixedly connected to the upper end of the treatment chamber 1.

[0031] A water supply pipe 47 is fixedly installed at the lower end of the connecting seat 46. The lower end of the water supply pipe 47 passes through the treatment chamber 1 and extends into the interior of the treatment chamber 1. A nozzle 48 is fixedly installed at the lower end of the water supply pipe 47. Multiple nozzles 48 are evenly arranged and are located above the screen 42.

[0032] Furthermore, in this embodiment, the exhaust gas generated during the spraying process enters the treatment chamber 1 through the air inlet pipe 2. The water pump 44 is started to draw liquid from the connecting chamber 43 and transport the liquid to the connecting seat 46 through the connecting water pipe 45. The connecting seat 46 guides the liquid into the water supply pipe 47. Multiple nozzles 48 at the lower end of the water supply pipe 47 spray the liquid evenly. Since the nozzles 48 are located above the screen 42, the liquid is sprayed onto the screen 42. During the upward process, the exhaust gas comes into full contact with the liquid on the screen 42, and performs preliminary purification treatment, such as removing some particulate matter in the exhaust gas and dissolving some soluble harmful substances.

[0033] Furthermore, in this embodiment, multiple nozzles 48 are provided in the spraying mechanism 4, which can evenly spray the liquid onto the screen 42, so that the exhaust gas and the liquid can come into full contact, thereby improving the efficiency of the preliminary treatment of exhaust gas and more effectively removing pollutants from the exhaust gas. Then, the activated carbon plate 55 is used for deep adsorption treatment, which can effectively remove a variety of pollutants from the exhaust gas. Example

[0034] Please see Figures 1-4 Furthermore, based on Embodiment 1, the following is obtained: the processing unit includes a lower placement frame 51, and fixed seats 52 are fixedly provided at both ends of the lower placement frame 51. The right end of the fixed seat 52 on the right side is fixedly connected to the processing chamber 1, and a suction fan 53 is fixedly provided at the left end of the fixed seat 52 on the left side.

[0035] An upper placement rack 54 is provided above the lower placement rack 51. Placement slots are provided inside both the lower placement rack 51 and the upper placement rack 54. An activated carbon plate 55 is provided between the lower placement rack 51 and the upper placement rack 54. The outer side of the activated carbon plate 55 is located close to the placement slot and is engaged with the inner wall of the placement slot.

[0036] The fixing part includes a connecting pipe 56, the lower end of which is fixedly connected to the upper placement frame 54. There are two connecting pipes 56 arranged at the front and rear. A handle 57 is fixedly arranged on the top surface of the upper placement frame 54. A bolt 58 is arranged above the connecting pipe 56. The lower end of the bolt 58 passes through the connecting pipe 56 and the lower placement frame 51 in sequence and is threadedly connected to the lower placement frame 51.

[0037] Furthermore, in this embodiment, the exhaust gas after spraying enters the treatment mechanism 5 area. The suction fan 53 works to generate suction, which causes the exhaust gas to pass through the activated carbon plate 55. The activated carbon plate 55 is placed in the placement slots of the lower placement rack 51 and the upper placement rack 54 and fixed by a snap-fit ​​method. The activated carbon has a large number of microporous structures, which can adsorb odors, harmful gas molecules, etc. in the exhaust gas, further purifying the exhaust gas. The gas after being adsorbed by the activated carbon plate 55 is discharged from the treatment chamber 1 under the action of the suction fan 53, completing the entire exhaust gas treatment process.

[0038] Furthermore, in this embodiment, the activated carbon plate 55 is fixed by the placement slots of the lower placement frame 51 and the upper placement frame 54, and is securely connected by the connecting pipe 56 and bolts 58. This structural design makes the installation and disassembly of the activated carbon plate more convenient, and facilitates the regular replacement of the activated carbon plate to ensure the treatment effect.

[0039] In use, the exhaust gas generated during spraying enters the treatment chamber 1 through the air inlet pipe 2. The water pump 44 starts, drawing liquid from the connecting chamber 43 and transporting it to the connecting seat 46 through the connecting water pipe 45. The connecting seat 46 guides the liquid into the water supply pipe 47, and multiple nozzles 48 at the lower end of the water supply pipe 47 spray the liquid evenly. Since the nozzles 48 are located above the screen 42, the liquid is sprayed onto the screen 42, and the exhaust gas comes into full contact with the liquid on the screen 42 during its ascent, undergoing preliminary purification treatment, such as removing some particulate matter and dissolved substances from the exhaust gas. After spraying, the waste gas, containing some soluble harmful substances, enters the treatment unit 5 area. The suction fan 53 operates, generating suction to force the waste gas through the activated carbon plate 55. The activated carbon plate 55 is placed in the placement slots of the lower placement rack 51 and the upper placement rack 54 and fixed by a snap-fit ​​method. Activated carbon has a large number of microporous structures, which can adsorb odors, harmful gas molecules, etc. in the waste gas, further purifying the waste gas. The gas after being adsorbed by the activated carbon plate 55 is discharged from the treatment chamber 1 under the action of the suction fan 53, completing the entire waste gas treatment process.
