Description

Technical Field

[0001] The utility model relates to the technical field of paraformaldehyde production, in particular to a paraformaldehyde production tail gas treatment device. Background Art

[0002] During the production process of paraformaldehyde, a large amount of harmful exhaust gas is generated, and the exhaust gas treatment device plays an important role in it. Most of the harmful gases are fixed in the particles. In order to effectively remove these particles.

[0003] Compared with the existing technology, there are problems: the existing exhaust gas treatment device usually uses a dust bag to filter the exhaust gas. As the exhaust gas is treated, more and more particulate matter accumulates in the dust bag, and the resistance of the exhaust gas passing through the dust bag will gradually increase. Therefore, the dust bag needs to be replaced or cleaned regularly. This maintenance work will cause the exhaust gas treatment device to be unable to operate continuously. The intermittent treatment method affects the continuity of the exhaust gas treatment. Although there are devices for automatically replacing dust bags, it will still affect the continuity of the device operation and reduce the efficiency of the exhaust gas treatment. For this reason, we proposed a polyformaldehyde production exhaust gas treatment device to solve the above problems. Utility Model Content
