Denitration catalyst production system and production tail gas treatment device thereof

The invention relates to the technical field of tail gas filtration, in particular to a denitration catalyst production system and a production tail gas treatment device thereof. The production tail gas treatment device of the denitration catalyst production system comprises a base, a first filtering mechanism and a second filtering mechanism. And the first filtering mechanism is a cyclone dust collector. The second filtering mechanism comprises a separation cylinder, a filtering assembly, an outer end cover and a control assembly. A mounting cylinder is arranged on the outer side of the separation cylinder, and an annular mounting groove is formed between the mounting cylinder and the separation cylinder; the filter assembly is arranged in the mounting groove and comprises a plurality of filter bags, and an airflow channel is formed in each filter bag. An annular cavity with a downward opening is formed in the outer end cover, and the air outlet pipe extends into the annular cavity. The control assembly is u
