Description
Technical field
The invention belongs to filter element of duster cleaner technical field, particularly a kind of modified tubular type filter-element dust collector is with scraping apparatus for ash.
Background technology
China's oil, natural gas resource shortage, coal will be the topmost primary energy of China quite over a long time in future.Yet coal conversion is utilized and is had problems and challenge in process, as low in comprehensive utilization ratio, environmental pollution serious, shortage of water resources and CO2 emissions large etc.Therefore, development of coal high-efficiency cleaning comprehensive utilization technique is realized the inevitable choice that energy-saving and emission-reduction are China's energy industry development.And just comprise the industrial policies such as " coal upgrading and comprehensive utilization of resources ", " for brown coal, lower-grade metamorphic bituminous staged conversion, comprehensive utilization " in < < clean coal technology development in science and technology " 12 " the ad hoc planning > > of national encourage growth.Now the dry dust removal of blast furnace gas becomes the developing direction of current blast furnace gas purification dedusting than the more significant advantage of wet dust removal with it.Because process requirements will be carried out dedusting to high-temperature dusty gas, realize gas solid separation and gas purification, method and the means of dedusting are a lot, as gravitational dust collection, inertial dust collection, cyclone separator, bag-type dust, electrostatic precipitation, ceramic dedusting, wet dust removal etc.Concrete equipment comprises as being bag-type dust, the cyclone dust removals such as mechanical dust collector, electric cleaner, filter collector and scrubber.What be relatively adapted to high-temperature dust removal is that the deduster of tubular type filter cartridge construction form filters and realizes gas solid separation with filter core, through the dusty gas filtering, enter air-purifying chamber, and the filter core that deduster is used its outer surface in dust removal by filtration process can adsorb a large amount of granule dusts, along with dust constantly increases, will affect filter quality, therefore the dust that need to pile up cartridge surface is removed, what generally use now is injection tube, utilize pulse jet means to realize reverse deashing, but the result of blowback must be to make the air having purified again enter the space before purification, because the purified gas scale of construction of each winding-up use is larger, secondary filter could purify again, be unfavorable for increasing work efficiency, and need to increase gas boosting equipment, also have, while jetting due to tubulose spout, can only clear up winding-up mouthful corresponding filter core position, spout can not change blowback direction, and in winding-up process, there is not easy cleaning of deashing dead angle, the solid all the more difficulty of unfavorable accumulation meeting of jetting is removed, therefore well thoroughly deashing dedusting, also there is the design of part producer to adopt dust removal with machine device, as manipulator front end is installed brush, or mechanical oscillation method, but complex structure not only, and easily damage the filter core of deduster, the air-purifying chamber that after filter core damage, dust enters deduster will removing pollutant gas be brought subsequent handling into and is caused great loss, and the more cleaning efficiency of filter core quantity is lowly difficult to clean out fast filter core in addition.Therefore, need badly and aspect dust removal with machine, make further improvement and bring new ideas and solve the problems referred to above, fill up the technological gap in the dust removal with machine field of filter element of duster.
Summary of the invention
