Description

Technical Field

[0001] The present application relates to the technical field of waste gas purification, and specifically to a packaging and printing waste gas purification device. Background Art

[0002] Packaging printing is the printing that uses various packaging materials as carriers. Decorative patterns, designs or texts are printed on the packaging to make the product more attractive or more descriptive, thereby conveying information and increasing sales. It includes the printing of packaging cartons, packaging bottles, packaging cans, etc. However, printing will produce waste gas. The components of printing waste gas usually include benzene, toluene, xylene, acetone, butanone, lipids, ethers and other highly volatile organic waste gases that spread into the surrounding air and pollute the air. Therefore, it is necessary to effectively collect and purify them.

[0003] The existing patent (publication number: CN212166970U) discloses an exhaust gas purification device for packaging printing, including a base, pulleys are fixedly connected to both sides of the bottom end of the base, a support rod is fixedly connected to the top end of the base, an external plate is fixedly connected to one side surface of the support rod, a slider is slidably connected to the inside of the external plate, a connecting cross plate is fixedly connected to one side surface of the slider, a cleaning box is fixedly connected to the bottom end of the connecting cross plate, a fan is fixedly connected to the inner wall of the top end of the cleaning box, a first gear is rotatably connected to the inner wall of the fan, a transmission chain is meshedly connected to the surface of the first gear, and a second gear is rotatably connected to the inner wall of the cleaning box.

[0004] The above patent points out a waste gas purification device for packaging printing, which sets a cleaning box. Under the rotation of the transmission chain, the second gear is driven to rotate, and the second gear is used to drive the loading net to rotate. The rotation of the loading net allows the activated carbon to absorb the waste gas in all directions, thereby achieving the purification effect. However, in actual use, the waste gas is only filtered by rotating the activated carbon. When the amount of waste gas generated by the packaging printing equipment is large, only activated carbon is used to filter the waste gas. The activated carbon is easily saturated and the filtering effect is poor, so it needs to be improved. At the same time, the activated carbon is arranged inside the loading net, and the loading net is fixed on the inner wall of the second gear. When the activated carbon adsorption is saturated, the second gear needs to be taken out, and then the loading net is taken out from the inside of the second gear, and then the activated carbon inside the loading net is taken out for replacement. The whole replacement process is relatively cumbersome, which results in a long time spent on replacement, affecting the work progress. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a packaging and printing waste gas purification device with the advantages of easy replacement, etc., which solves the problem that the waste gas purification device for packaging and printing only filters the waste gas by rotating the activated carbon during actual use. When the amount of waste gas generated by the packaging and printing equipment is large, only activated carbon is used to filter the waste gas. The activated carbon is easily saturated and the filtering effect is poor, so it needs to be improved. At the same time, the activated carbon is arranged inside the loading net, and the loading net is fixedly arranged on the inner wall of the second gear. When the activated carbon is saturated with adsorption, the second gear needs to be taken out, and then the loading net is taken out from the inside of the second gear, and then the activated carbon inside the loading net is taken out for replacement. The whole replacement process is relatively cumbersome, which leads to the problem that the replacement takes a long time and affects the work progress.

[0037] In this embodiment, an activated carbon adsorption layer 25, a synthetic fiber material filter layer 26 and a membrane separation material filter layer 27 are arranged inside the filter barrel 23. During use, impurities, odors and other harmful substances in the gas are more comprehensively filtered and adsorbed, thereby improving the filtering effect. At the same time, the membrane separation material and the synthetic fiber material have good durability and stability, which can extend the service life of the filter barrel 23 and reduce the frequency of replacing the filter barrel 23.

[0038] It should be noted that the membrane separation material filter layer 27 is made of polymer materials, such as cellulose esters, polyamides, and aromatic heterocyclic polymers, and uses a separation membrane component to purify and cleanse the gas. The synthetic fiber material filter layer 26 mainly includes polyamide fibers, polyester fibers, polyacrylonitrile fibers and other filter materials.

[0039] The working principle of the above embodiment is:

[0040] The rotation output of the first motor 12 will drive the first screw 13 to rotate, thereby adjusting the height of the installation pipe 9 and the collection cover 10. The height of the equipment can be adjusted according to actual needs. When the packaging and printing equipment generates exhaust gas, the exhaust gas is first collected by the collection cover 10, and the exhaust fan 28 is started to suck the exhaust gas into the filter barrel 23 through the installation pipe 9, the telescopic pipe 8 and the connecting piece 7. There are three layers of filter materials inside the filter barrel 23, namely, an activated carbon adsorption layer 25, a synthetic fiber material filter layer 26 and a membrane separation material filter layer 27. The exhaust gas first passes through the activated carbon adsorption layer 25 to adsorb harmful substances and The exhaust gas passes through a filter layer 26 made of synthetic fiber material to further filter out particulate matter in the exhaust gas, and finally passes through a filter layer 27 made of membrane separation material to further separate and filter harmful substances in the exhaust gas using the characteristics of membrane separation technology. The exhaust gas after three layers of filtration is discharged from the upper end of the filter barrel 23. When the filter material in the filter barrel 23 is saturated or needs to be replaced, the filter barrel 23 can be removed from the connector 7 by rotating it. At this time, the new filter barrel 23 can be directly screwed into the connector 7 to complete the replacement of the filter barrel 23. The replacement process is simple and quick, with little impact on work efficiency.
