Adjustable jetting dust cleaning system of pulse-jet bag dust collector

Abstract

The invention provides an adjustable jetting dust cleaning system of a pulse-jet bag dust collector. The adjustable jetting dust cleaning system comprises a bag chamber box and an air bag, wherein theinterior of the bag chamber box is horizontally provided with an inner jetting pipe, and the inner jetting pipe is installed on the ceiling through an adjustable fixed device; the air bag is connected with an outer jetting pipe, and the air outlet end of the outer jetting pipe is penetrated into the interior of the bag chamber box to be connected with the inner jetting pipe; an adjustable flangeis fixedly arranged on the outer jetting pipe in a sleeving manner, and the adjustable flange is movably connected with the outer side wall of the bag chamber box. According to the device, the heightsof the jetting pipes can be adjusted according to different actual operation working conditions, effective dust cleaning is realized, and the problem that an opening in a filter bag is broken or dustcleaning at the bottom of the filter bag is insufficient caused by the fact that the jetting at the opening of the filter bag is excessive or insufficient is avoided.

Description

technical field [0001] The invention relates to a pulse bag type dust collector, in particular to a blowing and cleaning system of the pulse bag type dust collector with adjustable blowing pipe height. Background technique [0002] In recent years, large-scale pulse bag type dust collectors have been widely used for purification treatment of dusty flue gas generated in cement, steel, electric power, metallurgy and other industries. One of the core components of the pulse bag filter is a blowing dust cleaning system composed of pulse valves, air bags, bag room blowing pipes, bag room boxes, flower plates and other components. The flower plates are fixed inside the bag room box bottom end. The design of the existing blowing dust cleaning system is: several blowing pipes arranged horizontally are installed on the air bag, each blowing pipe is fixed on the flower plate through the supporting channel steel, and the blowing pipe passes through the side of the bag room box. The w...

AI Technical Summary

Problems solved by technology

Under different working conditions (air volume, dust concentration), it will cause excessive or insufficient blowing pressure at the filter bag mouth, which will easily cause damage to the filter bag mouth or insufficient dust removal at the bottom of the filter bag, which will affect the dust removal effect of the filter bag. Thus shortening the service life of the filter bag
