Description

technical field

[0001] The invention relates to a rotary pulse-jet filter bag type dust collector for off-line cleaning and on-line maintenance, in particular to a bag filter for a cylinder-shaped main shell, which belongs to the technical field of environmental protection equipment. It is widely used in the control of smoke and dust in metallurgy, electric power, chemical industry, construction and other fields. Background technique

[0002] In metallurgy, electric power, chemical industry, construction and other fields, there will be a lot of smoke and dust to be treated, which usually requires the use of pulse jet filter bag dust collectors. However, conventional pulse-jet filter bag filters at home and abroad generally have shortcomings and disadvantages such as complex structure, high resistance, large floor area, difficult layout of inlet and outlet air ducts, and offline cleaning but no online maintenance.

[0003] In order to effectively control the smoke and dust, ...
