Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of bamboo pulp paper, in particular to an exhaust gas purification device for bamboo pulp paper production. Background Art

[0002] Bamboo pulp paper is made from bamboo pulp alone or in a reasonable proportion with wood pulp or straw pulp, through papermaking processes such as steaming and bleaching. The waste gas mainly comes from the flue gas generated by the combustion of power boilers, alkali recovery boilers and lime kilns during the processing of bamboo pulp paper. If these waste gases are directly discharged into the environment without treatment, they will cause serious harm to the environment and human health.

[0003] During the use of traditional exhaust gas purification devices, large particulate pollutants in the exhaust gas will adhere to the filter net, so the filter net often needs to be cleaned. Since the filter net is mostly fixed by locking bolts, it is necessary to use external equipment to remove the locking bolts one by one, which is inconvenient. In addition, multiple disassembly and assembly may easily damage the bolts or threads, resulting in difficulties in subsequent installation or the need to replace the bolts. Utility Model Content
