Description

Technical Field

[0001] The present invention belongs to the technical field of waste gas purification and recycling, and specifically relates to a waste gas purification and recycling device. Background Art

[0002] At present, various waste gases generated during the production processes of shoe factories, semiconductor factories, and printing factories not only pose a threat to the lives and health of employees in the workshop, but also pollute the atmospheric environment when directly discharged into the atmosphere. Therefore, it is necessary to timely treat the waste gas generated during the production process to minimize the content of waste gas in the workshop. The current mainstream method is to use a suction device to uniformly extract the waste gas generated in the workshop and transport it to a waste gas treatment workshop or a waste gas treatment device externally placed in the operation workshop for treatment.

[0003] Existing waste gas treatment devices mainly use a combination of ultraviolet light and photocatalyst for treatment. The waste gas is introduced into a treatment chamber equipped with ultraviolet lamps and photocatalyst materials from one end and directly discharged from the other side of the treatment chamber. Such treatment devices are large in volume, occupy a large amount of space, and are inconvenient to carry. Summary of the Invention

[0046] The air extraction component 200 in this embodiment includes a main pipeline 210, air extraction branch pipes 220, an air extraction hood 230, a manual switch 240, and an intake pipe 250. There are two intake pipes 250 on the top of the profile frame 110. Main pipelines 210 are provided on both of the two intake pipes 250. A plurality of air extraction branch pipes 220 are provided on each main pipeline 210.

An intake fan is provided on the two intake pipes 250, and solenoid valves are provided on all the air extraction branch pipes 220.

[0047] An adjustment frame 260 is provided on the main pipeline 210 in this embodiment, and the main pipeline 210 is supported by the adjustment frame 260.

[0048] One end of the main pipeline 210 away from the profile frame 110 in this embodiment is provided with a splitter 270, and the main pipeline 210 is connected to more main pipelines 210 through the splitter 270.

[0049] An air extraction fan is provided inside the splitter 270 in this embodiment.

[0050] The secondary circulation device 300 of this embodiment includes an exhaust pipe 310 and a gas distribution box 320. The air outlet of the sterilization mechanism 190 is connected to the gas distribution box 320 through the exhaust pipe 310. An ozone decomposer 321 is provided in the gas distribution box 320. With this design structure, the waste gas and excess ozone are fully treated and then discharged back into the room to form a secondary circulation.

[0051] The sterilization mechanism 190 of this embodiment includes a first exhaust pipe 191, a second filter pipe 192, and a connecting pipe 193. The first exhaust pipe 1910 is arranged in parallel with the second filter pipe 192. The first exhaust pipe 191 is connected to the second filter pipe 192 through the connecting pipe 193. An opening is provided on the side of the second filter pipe 192 away from the first exhaust pipe 191. Activated carbon 194 is provided in the opening, and a filter cotton 195 is wrapped outside the opening. An exhaust fan 196 is provided in the first exhaust pipe 191. The cross-flow fan 160 is located below the second filter pipe 192 for delivering the air below into the second filter pipe 192.

[0052] In the profile frame 110 of this embodiment, a horizontally arranged filter 180 and a vertically arranged partition board are provided. The filter 180 and the partition board divide the space inside the profile frame 110 into four parts, including the upper left space, the lower left space, the upper right space, and the lower right space.

[0053] The air inlet pipe 250 of this embodiment communicates with the upper left space.

[0054] The opening of the second filter pipe 192 of this embodiment communicates with the upper right space, and an air exchanger 400 is provided in the lower right space.

[0055] Working principle: The air extractor on the air inlet pipe 250 extracts waste gas through the main pipe 210 and the air extraction branch pipe 220. The air extraction hood 230 is located above the waste gas source, which can extract air more comprehensively and fully. Then the waste gas enters the upper left space inside the profile frame 110. With the operation of the air exchanger 400, the waste gas enters the lower left space from the upper left space. The waste gas passes through the filter 180 for the first time, realizing the first filtration. Then it enters the lower right space from the lower left space and is discharged to the upper right space through the air exchanger 400. During this process, the waste gas passes through the filter 180 for the second time, realizing the second filtration. During the flow of the waste gas, it also contacts the pre-filter plate 150. The activated carbon 194 in the pre-filter plate 150 can adsorb impurities. The waste gas entering the upper right space has been filtered twice to become semi-waste gas. The semi-waste gas enters the first exhaust pipe 310 through the filter cotton 195 and the activated carbon 194. At this time, the semi-waste gas is fully filtered and treated to form clean gas, and finally is discharged through the gas distribution box 320.

[0056] It should be noted that an ultraviolet lamp is provided inside the second filter tube 192, an ozone generator 101 is provided inside the lower left space, an ozone decomposer is provided inside the air distribution box 320, and the semi-exhaust gas is mixed with ozone for sufficient sterilization treatment and finally decomposed by the ozone decomposition device, and clean air is discharged. In this process, the exhaust gas will be purified by the ozone generated by the ozone generator 101, irradiated and sterilized by the ultraviolet lamp, and the harmful components will be degraded by photo-touch; among them, the excess ozone produced will finally enter the ozone decomposer and be secondarily purified and decomposed through high temperature and the ozone decomposition filter screen, and the purified clean air is directly discharged into the workshop interior.

[0057] The above-described embodiments merely represent certain implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention patent; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention; therefore, the protection scope of the present invention patent shall be subject to the appended claims.
