Abstract
The invention discloses an improved ash scraping device for a pipe-type filter element dust remover, and particularly relates to an ash scraping device for a dust remover filter element. The ash scraping device comprises a scraper blade and a push-pull mechanism, wherein a plurality of filter element penetrating holes are formed in the scraper blade; rotary ring scraper disks are arranged in the filter element penetrating holes; a cavity air channel is formed in the scraper blade; an air blowing opening leading to the ring scraper disks is formed in the cavity air channel; spiral blades are arranged on the inner sides of the ring scraper disks; air inducing plates are arranged at positions, which correspond to nozzles, on the spiral blades; extending tongue shovel plates are arranged on the inner circumferential sides of the ring scraper disks at intervals. When the ash scraping device is used for cleaning gathered ash, the push-pull mechanism drives the whole scraper blade to move along the filter element so as to clean the ash on all the filter elements for one time, and the cleaning efficiency is very high; the cavity air channel is formed in the scraper blade, so that the weight of the scraper blade is reduced; furthermore, the spiral blades can be driven to rotate to implement ring scraping successfully; flow-out air can blow the gathered ash during ash scraping; moreover, the tongue shovel plates are loose, so that gathered ash cleaning is thoroughly implemented.
Description
Technical field
The invention belongs to filter element of duster cleaner technical field, particularly a kind of filter element of duster 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.But coal conversion utilizes and has 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 policy 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 " the 12 " 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 filter core of tubular type filter cartridge construction form filters and realizes gas solid separation, enter air-purifying chamber through the dusty gas filtering, 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 need the dust that cartridge surface is piled up to remove, 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 winding-up 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 not only complex structure, and easily damage the filter core of deduster, after filter core damage, just must stopping production just can carry out more renew cartridge, and the dust air-purifying chamber that enters deduster will removing pollutant gas brings subsequent handling into and cause great loss, 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
The object of the invention is to solve the problems of the technologies described above, provide a kind of can fast dust-removing, the good filter element of duster of ash-removal effect is with scraping apparatus for ash.
For achieving the above object, the technical solution used in the present invention is: a kind of filter element of duster, with scraping apparatus for ash, comprises scraper plate and push-pull mechanism, and some filter core perforation are set on described scraper plate, and described filter core site of perforation arranges ring and scrapes cutterhead.
Cavity air flue is set in described scraper plate, and the inflatable mouth of filter core perforation is led in the setting of described cavity air flue.
On described scraper plate, ash leakage hole is set.
