Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas treatment device for cellulose ethers. Background Technology

[0002] The production of cellulose ethers generates waste gases containing volatile organic compounds and other harmful gases. If these waste gases are emitted directly without treatment, they will have serious consequences for the environment and human health. Therefore, effective waste gas treatment methods must be adopted to purify these gases.

[0003] However, in the existing technology, the adsorption method is used to filter and purify waste gas. Most adsorption materials are fixedly installed inside the treatment device and are not easy to disassemble. If they are not replaced and cleaned for a long time, it will affect the waste gas treatment effect and reduce the efficiency of waste gas purification. Moreover, most waste gas treatment processes are prone to releasing unqualified gases, which will pollute the surrounding environment, affect the physical and mental health of workers, and pose certain safety hazards. Utility Model Content

[0004] The purpose of this invention is to address the problems in existing technologies where waste gas is treated using adsorption for filtration and purification. Most adsorption materials are fixed inside the treatment device, making them difficult to remove. Failure to replace or clean them over a long period affects the waste gas treatment effect and reduces purification efficiency. Furthermore, most waste gas treatment processes easily release substandard gases, causing pollution to the surrounding environment, affecting the physical and mental health of workers, and posing certain safety hazards.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a waste gas treatment device for cellulose ethers, comprising: a treatment box, wherein a rectangular groove is formed on the upper side of one side of the treatment box, and a hollow box is movably embedded inside the rectangular groove, and further comprising:
