Pneumatic dust-cleaning device of bag-type dust remover and dust-cleaning method thereof

Abstract

The invention discloses a pneumatic dust-cleaning device of a bag-type dust remover and a dust-cleaning method thereof. The pneumatic dust-cleaning device comprises a mechanical part and a pneumatic part, wherein the mechanical part comprises a filter bag, a drawing rod and a cylinder; the filter bag is a constituent part of the bag-type dust remover, and a piston rod of the cylinder is connected with the filter bag by the drawing rod. When the mechanical part is started to enter a dust-cleaning program by the pneumatic part, the dust-cleaning method is carried out in such a way that: the piston rod of the cylinder moves upwards to drive the drawing rod to move upwards and the filter bag is lifted by the drawing rod to change the filter bag from an expanding state into a pursing state; after moving upwards to the limit position of the cylinder, the piston rod of the cylinder moves downwards to drive the drawing rod to move downwards; and the filter bag is pushed downwards by the drawing rod so that the filter bag is restored to the expanding state. Because a cylinder oscillating type cleaning way is adopted in the dust-cleaning device of the bag-type dust remover in a purifying dust removing bin, the dust-cleaning device has better cleaning effect and enable dust-cleaning to be more thorough.

Description

technical field [0001] The invention relates to a dust removal device of a bag filter and a method thereof, in particular to a pneumatic dust removal device of a bag filter and a method thereof. Background technique [0002] The "Twelfth Five-Year" environmental protection plan proposes to further strengthen the control of primary particulate matter emissions, requiring in-depth treatment of existing water sources, steel plants, power plants and industrial boilers, installation of efficient dust removal facilities, and reduction of fugitive emissions. However, at present, most of the shipbuilding enterprises and container production units in the country do not have welding fume absorption devices in the welding workplaces. The welding fumes are all fugitive emissions. Occupational diseases occur from time to time, and the health of employees cannot be protected. In a few places where the welding fume purification system is installed, the fume generated by welding can be deal...

Problems solved by technology

[0006] (1) The shape is large, and it is inconvenient to manufacture and install;

[0007] (2) High cost;

[0008] (3) When the pulse is pulsed, the ash is instantly raised in the purification and dust removal chamber, and the ash that is blown back is sucked into the filter bag, and the ash removal is not complete
