Description
Technical field
The present invention relates to a kind of deduster, especially relate to a kind of pulse bag type dust collector.
Background technology
The ash purifying device in industry pattern is a lot, but the main at present pulse bag type dust collector that adopts, the pressure loss and the efficiency of dust collection that influence effects of energy saving and emission reduction then are two Specifeca tion speeifications of pulse bag type dust collector.Pulse bag type dust collector mainly is made up of upper box, jetting deashing device, card, filter bag, middle casing, air inlet, air outlet, deflector, ash bucket etc.
During work, dusty gas enters deduster by the air inlet on lower box in being arranged on or ash bucket top, being evenly distributed to filter bag behind the air flow guiding plate filters, dust is delayed at the filter bag outer surface then, clean gas enters upper box from filter bag, after the air outlet that is arranged on the upper box is discharged.Jetting deashing device can be removed the dust of detention on the filter bag outer surface, and the dust under being eliminated falls into ash bucket by deadweight.
The pulse bag type dust collector structural shape of selling on the domestic and international market is the same substantially at present, its difference be mainly reflected in following some: first, jetting deashing device deashing ability difference, and deashing ability difference mainly be by the ability difference of pulse valve and winding-up pipe each the nozzle operation ability is inconsistent causes.Effective actual internal area of using at present more 3 inches through type pulse valves of Australian Goyen company at home only is 3600mm
2, and effective actual internal area of the similar pulse valve of our company is 4700mm
2The winding-up pipe is gone up the ash-removal effect that each nozzle diameter uniformity big or small and ability to work directly influences corresponding filter bag, when the deashing energy is excessive, ash-removal effect is better, the filter bag pressure loss is lower behind the deashing, but destroyed dust layer attached to the filtration of filter bag outer surface, cause efficiency of dust collection to descend, dust discharge amount increases; Otherwise when the deashing energy shortage, efficiency of dust collection is higher, but ash-removal effect is not good enough, and the filter bag pressure loss is higher.The second, deduster inlet and outlet wind speed is different, causes its pressure loss different.The import and export wind speed of the deduster of Xiao Shouing is all more than 12m/s in the market, even more than the 20m/s, only the pressure loss herein is just more than 100～300Pa.The 3rd, the pattern of deflector and that the position is set is different in the deduster, the inner dust-contained airflow skewness of most in the market dedusters causes the suffered load of each filter bag inhomogeneous, and not only the pressure loss is big, and efficiency of dust collection reduces.
Summary of the invention
