Specific embodiments

[0023] The technical solutions of the embodiments of the present utility model will be explained and described below with reference to the drawings of the embodiments of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work all fall within the protection scope of the present utility model.

[0024] The following specifically describes an efficient and energy-saving waste gas treatment device for an aluminized paper coating machine according to an embodiment of the present utility model with reference to the drawings.

[0025] Embodiment 1

[0026] For ease of understanding, please refer to Figures 1 to 4 An embodiment of an efficient and energy-saving waste gas treatment device for an aluminized paper coating machine provided by the present utility model, including a combustion tube 1. The combustion tube 1 is provided with a waste gas treatment component and a heat exchange component. Both ends of the combustion tube 1 are fixedly installed with filtered gas pipes 2, and one end of one of the filtered gas pipes 2 is fixedly installed with an exhaust pipe 3;

[0027] The waste gas treatment component includes a mounting block 401, an igniter 402, a solenoid valve nozzle 403, a combustion-supporting gas pipe 404, a flow guiding groove 405 and a water collecting tank 406. The mounting block 401 is fixedly installed at one end of the combustion tube 1. The igniter 402 and the solenoid valve nozzle 403 are fixedly installed in the middle of the mounting block 401. The combustion-supporting gas pipe 404 is fixedly installed at the input end of the solenoid valve nozzle 403. The flow guiding groove 405 is opened at the bottom of the combustion tube 1. The water collecting tank 406 is threadedly connected to the bottom of the flow guiding groove 405. The igniter 402 and the solenoid valve nozzle 403 extend into the interior of the combustion tube 1, and the water collecting tank 406 is communicated with the interior of the combustion tube 1.

[0028] It should be noted that by setting the igniter 402 and the solenoid valve nozzle 403, specifically, when discharging the waste gas of volatile organic compounds (VOCs) into the combustion tube 1 through the filter gas pipe 2, the solenoid valve nozzle 403 should be installed at the front end of the filter gas pipe 2 for air intake to prevent backfire and quantitatively control the proportion of discharging volatile organic compounds (VOCs) into the combustion tube 1. Then, after introducing the waste gas of the coater containing volatile organic compounds into the combustion tube 1, the combustion-supporting gas is introduced through the solenoid valve nozzle 403 in a controlled amount and ignited by the igniter 402 to generate carbon dioxide and water, so as to quickly treat the volatile organic compounds in the waste gas of the coater. Then, the water will flow into the water collection tank 406 through the diversion groove 405.

[0029] Example 2

[0030] In some embodiments, such as Figure 4 shown, the heat exchange component includes a heat exchange hollow outer sleeve 501, a filter screen 502, a plurality of heat exchange plates 503 and an air extraction pipe 504. The heat exchange hollow outer sleeve 501 is sleeved on the outer wall of the combustion tube 1. The filter screen 502 is fixedly installed inside one end of the heat exchange hollow outer sleeve 501. A plurality of heat exchange plates 503 are fixedly connected inside the heat exchange hollow outer sleeve 501. One end of the air extraction pipe 504 is fixedly connected to the side wall of one end of the heat exchange hollow outer sleeve 501. The inner surface of the heat exchange hollow outer sleeve 501 abuts against the outer wall surface of the combustion tube 1. A plurality of heat exchange plates 503 are arranged in an annular array inside the heat exchange hollow outer sleeve 501. One end of the air extraction pipe 504 is communicated with the inside of the heat exchange hollow outer sleeve 501.

[0031] It should be noted that by setting the heat exchange hollow outer sleeve 501 outside the combustion tube 1, a large amount of heat generated during the treatment of organic compounds is transferred from the combustion tube 1 to the heat exchange hollow outer sleeve 501. Then, the external fan sucks air through the provided air extraction pipe 504. When sucking air, the air will be heated by the heat exchange plates 503 inside the heat exchange hollow outer sleeve 501, and then used for the coater to evenly coat the slurry on the surface of the substrate and then dry it, so as to reuse the heat energy and save energy.

[0032] Working principle: When in use, first, a quantitative amount of volatile organic compounds are discharged into the combustion tube 1 through the solenoid valve nozzle 403 at the front end of the filtering air pipe 2 for discharging waste gas of volatile organic compounds (VOCs). At the same time, a combustion-supporting gas is introduced through the solenoid valve nozzle 403 in a controlled amount and is ignited by the igniter 402 to undergo an oxidation reaction, generating carbon dioxide and water, so as to rapidly treat the volatile organic compounds in the waste gas of the rapid coater. At the same time, a large amount of heat generated during the treatment of organic compounds is transferred to the heat exchange hollow outer sleeve 501 through the combustion tube 1, and then air is sucked in by an external fan through the air suction pipe 504 provided. When sucking air, the air is heated by the heat exchange plate 503 inside the heat exchange hollow outer sleeve 501, and then is used for the coater to uniformly coat the slurry on the surface of the substrate and then dry it, thus reusing the heat energy and saving energy.

[0033] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
