The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] The first embodiment of the present application is:

[0020] See also Figures 1 to 3 ,in, Figure 1 This is a schematic cross-sectional structure diagram of a cleaning tower of a photo-oxidation catalytic VOC waste gas collection device according to the first embodiment of the utility model. Figure 2 1 is a schematic diagram of the structure of the cleaning component of the first embodiment of the utility model.

The utility model provides a photo-oxidation catalytic VOC waste gas collection device, including a waste gas box 101, a connecting pipe 102, a cleaning component, a filter component and an air guide component. The cleaning component includes a cleaning tower 103, a connecting seat 104, a cleaning plate 105 and a collection tank 106. The filter component includes a motor 107, a rotating shaft 108, a rotating seat 109, a connecting plate 110, an activated carbon filter layer 111, an adsorption layer 112 and a medium-efficiency filter layer 113.

The above-mentioned scheme solves the problem that the photo-oxidation catalytic VOC waste gas collection device cannot clean the filter component when in use, resulting in the need to frequently replace the filter component when the device is used, which increases the processing cost. It can be understood that the above-mentioned scheme can be used in the scenario of cleaning the filter component during VOC waste gas collection and treatment, and can also be used to solve the air guide problem during VOC waste gas treatment.

[0021] According to the present specific embodiment, the connecting pipe 102 is fixedly connected to the exhaust box 101 and is located on the outside of the exhaust box 101. The cleaning tower 103 is fixedly connected to the connecting pipe 102 and is located on the side of the connecting pipe 102 away from the exhaust box 101. There are multiple connecting seats 104, and the multiple connecting seats 104 are respectively located inside the cleaning tower 103. Four cleaning plates 105 are respectively fixedly connected to the outside of each connecting seat 104, and four collecting tanks 106 are respectively detachably connected to the outside of each connecting seat 104. The filter assembly and the air guide assembly are respectively connected to the cleaning tower 103, and the spray assembly is connected to the air guide assembly. The exhaust box 101 is used to store the exhaust gas generated by the external equipment. The connecting pipe 1 02 is used to connect the exhaust gas box 101 and the cleaning tower 103, the connecting seat 104 provides support for the cleaning plate 105, and the collecting tank 106 is used to store the cleaned impurities. When the exhaust gas is treated, the exhaust gas enters the cleaning tower 103 through the connecting pipe 102, and the exhaust gas is filtered by the filter assembly. When the filter assembly needs to be cleaned, the motor 107 drives the filter assembly to rotate, and the bottom surfaces of the activated carbon filter layer 111, the adsorption layer 112 and the medium-efficiency filter layer 113 are cleaned through the cleaning plate 105. The cleaned impurities and wastes are temporarily stored in the collecting tank 106. When the filter assembly is replaced, the waste in the collecting tank 106 is cleaned at the same time, thereby extending the service life of the filter assembly.

[0022] Among them, the motor 107 is fixedly connected to the cleaning tower 103 and is located at the top of the cleaning tower 103. The rotating shaft 108 is connected to the motor 107 and passes through the cleaning tower 103 and the connecting seat 104. The rotating seat 109 is rotatably connected to the rotating shaft 108 and is located at the bottom of the cleaning tower 103. The motor 107 provides power for the filter assembly. When the filter assembly is replaced or cleaned, the rotation of the motor 107 drives the rotating shaft 108 to rotate along the rotating seat 109, and at the same time drives the connecting plate 110 and the activated carbon filter layer 111, the adsorption layer 112 and the medium-efficiency filter layer 113 to rotate, so that the filter assembly can be easily replaced and cleaned.

[0023] Secondly, there are multiple connecting plates 110, and the multiple connecting plates 110 are respectively fixedly connected to the rotating shaft 108 and are respectively located on the outside of the rotating shaft 108. The activated carbon filter layer 111 is detachably connected to the connecting plate 110 and is located between the connecting plates 110. The adsorption layer 112 is detachably connected to the connecting plate 110 and is located between the connecting plates 110. The medium-efficiency filter layer 113 is detachably connected to the connecting plate 110 and is located between the connecting plates 110. The activated carbon filter layer 111, the adsorption layer 112 and the medium-efficiency filter layer 113 detachably connected between the connecting plates 110 are respectively used for filtering, adsorbing and treating the exhaust gas. The activated carbon filter layer 111, the adsorption layer 112 and the medium-efficiency filter layer 113 are separated by the connecting plate 110, so that the activated carbon filter layer 111, the adsorption layer 112 and the medium-efficiency filter layer 113 are easy to replace.

[0024] Again, the air duct 114 is fixedly connected to the cleaning tower 103 and is located on a side of the cleaning tower 103 away from the connecting pipe 102. The return pipe 115 is fixedly connected to the air duct 114 and passes through the cleaning tower 103. The solenoid valve 116 is fixedly connected to the air duct 114 and is located on the outside of the air duct 114. The air duct 114 guides the filtered exhaust gas. When the equipment does not filter the exhaust gas up to standard, the solenoid valve 116 is closed to allow the air duct 114 to guide the exhaust gas into the return pipe 115, and the exhaust gas is guided back to the cleaning tower 103 through the return pipe 115, so as to facilitate the re-filtration of the exhaust gas. After the filtered exhaust gas meets the standard, the solenoid valve 116 is opened to guide the exhaust gas through the air duct 114 for subsequent treatment.

[0025] When using the photocatalytic VOC waste gas collection device of this embodiment, the waste gas box 101 is used to store the waste gas generated by the external device, the connecting pipe 102 is used to connect the waste gas box 101 and the cleaning tower 103, the connecting seat 104 provides support for the cleaning plate 105, and the collecting tank 106 is used to store the impurities after cleaning. When the waste gas is processed, the waste gas enters the cleaning tower 103 through the connecting pipe 102, and the waste gas is filtered by the filter component. When the filter component needs to be cleaned, the motor 107 drives the filter component to clean the filter component. The filter assembly rotates, and the bottom surfaces of the activated carbon filter layer 111, the adsorption layer 112 and the medium-efficiency filter layer 113 are cleaned through the cleaning plate 105. The cleaned impurities and wastes are temporarily stored in the collecting tank 106. When the filter assembly is replaced, the wastes in the collecting tank 106 are cleaned at the same time, thereby extending the service life of the filter assembly and solving the problem that the filter assembly cannot be cleaned when the photo-oxidation catalytic VOC waste gas collection device is in use, resulting in the need to frequently replace the filter assembly when the device is in use, thereby increasing the processing cost.

[0026] The second embodiment of the present application is:

[0027] Based on the first embodiment, please refer to Figure 4 ,in, Figure 4 It is a schematic diagram of the overall structure of the photo-oxidation catalytic VOC waste gas collection device of the second embodiment of the utility model.

[0029] According to this specific embodiment, the spray tower 201 is fixedly connected to the air duct 114 and is located at one end of the air duct 114 away from the cleaning tower 103. The demister plate 202 is detachably connected to the spray tower 201 and is located inside the spray tower 201. The spray tower 201 is used to spray the exhaust gas so that the water-soluble substances in the filtered exhaust gas are carried away by the spraying water. The exhaust gas then passes through the demister plate 202 to process the water vapor in the gas, so that the exhaust gas can be treated more efficiently.

[0030] By using the photo-oxidation catalytic VOC waste gas collection device of this embodiment, the water-soluble substances in the waste gas after filtration are taken away by the spray water sprayed from the spray tower 201, and the waste gas then passes through the demister plate 202 to process the water vapor in the gas, so that the waste gas can be processed more efficiently.
