Description

Technical Field

[0001] The utility model relates to the technical field of waste gas utilization, in particular to a waste gas utilization device for coating and drying which is convenient for clearing blockage. Background Art

[0002] In the printing, coating and other industries, printing inks and glues contain a large amount of organic solvents. After printing and coating, the printed paper and coating are generally dried in an oven. During the drying process, the organic solvents are heated in the oven to produce a large amount of organic waste gas. If they are discharged directly, it will not only cause a lot of pollution, but also waste heat and organic solvents. If activated carbon fiber is used for simple adsorption and recovery before discharge, some of the organic solvents can be recovered.

[0003] Chinese Patent Authorization Announcement No. CN 221808427 U discloses a waste gas utilization device for coating and drying with a purification component, including a waste gas recovery box, an air inlet pipe installed at the top of the waste gas recovery box, and a purification seat installed inside the waste gas recovery box. The utility model can filter out coating fluff and large particles of impurities in the waste gas by installing a filter, and at the same time, can further adsorb harmful substances in the waste gas through the activated carbon adsorption cloth, thereby facilitating subsequent recycling work. When the filter needs to be cleaned, it is only necessary to release the engagement between the card slot and the card block, so that the filter can be removed from the inner side of the connecting seat for cleaning or replacement, effectively extending its service life and use value. At the same time, by setting the cross-section of the partition plate to be wavy, the flow rate of the waste gas can be extended, thereby more effectively improving the purification work efficiency.
