Abstract
The invention relates to a coke oven coke side small furnace end dust removal device. A furnace top dust collecting fan is arranged above the reference line of a furnace top, and is communicated with a small furnace end dust removal main pipe; the small furnace end dust removal main pipe is transversely arranged under a coaling flue gas conversion valve, a vertical coal truck triboelectric support is arranged at two ends of every two adjacent small furnace ends respectively so as to form a structure that the coaling flue gas conversion valve is positioned between adjacent coal truck triboelectric supports; every two adjacent small furnace ends share one coating hopper type dust collection hood, and each coating hopper type dust collection hood is communicated to the small furnace end dust removal main pipe by using branch pipes and flap valves respectively. The coke oven coke side small furnace end dust removal device has the advantages that the device efficiently solves the problem that an existing ground station or coke barrier vehicle on-board coke discharging dust removal device cannot eliminate smoke escape of a chamber type coke oven small furnace end, can utilize a dry quenching environment dust removal station or a coaling ground station dust removal station provided with a back-fire relief valve, and does not need a dust remover, so that the investment can be saved, the device is mounted between coke oven tops, and has the advantages of long service life, small failures, low maintenance cost and more convenient maintenance construction compared with a device mounted on the coke barrier vehicle on-board fan.
Description
Technical field
The present invention relates to Environmental Protection Technology in Coking Industry field, particularly the little burner cleaning apparatus of a kind of cell-type coke oven coke side.
Background technology
Coking is that multi-source pollutes industry, and flue dust mainly pollutes emissions in coking production process.Modern cell-type coke oven is generally all equipped with vehicular or ground standing posture to coaling and coke discharging and dedusting system, and wherein the application of ground standing posture dust-removal system is comparatively extensive.Ground standing posture coke discharging and dedusting system utilizes coupling fluid-structure or variable frequency control blower fan to purify through coke discharging and dedusting device by being arranged on collecting hood on coke guide by its most flue dust collecting mainly for coke side flue dust.But the little furnace head position of coke side still has the loss of part flue dust and worsens operating environment.The little burner of coke side discharges of the coke that flue dust derives from blow-on door, red Jiao enters grid at first, continues coke pushing and close 4 stages of fire door, wherein red Jiao to enter grid stage flue dust at first the most outstanding.
Because the front of the single little burner of coke side, firedoor frame and furnace stay is to coke guide orbit centre apart from there are differences, bucket type dust gathering arrester scratching furnace stay is covered for preventing leading burnt grid, its nearly body of heater end and coke side little burner front spacing are comparatively large, thus leave structural defect for flue dust from little burner loss.
Discharge of the coke that flue dust temperature is high, transient heat buoyancy and dirt large-minded, but both coke guide grid of coke guide top and quenching car compartment top cover bucket type dust gathering arrester area ratio great disparity, ground dedusting blower fan suction is mainly allocated to quenching car compartment top and covers bucket type dust gathering arrester, add that leading burnt grid covers between bucket type dust gathering arrester and little burner and there is interstice coverage, therefore cause part flue dust from little burner loss.In order to improve its dust removing effects, some coal chemical enterprises take perforate on the side plate of leading Jiao Shanding and cover the nearly body of heater side of bucket type dust gathering arrester and additional vehicle-mounted fan assists dust suction, and Ye Youyici enterprise takes the adjustment terrestrial station dedusting fan time parameter that runs up in advance to enter grid stage suction at first to increase red Jiao in advance; But it is all undesirable to produce effects, but also adds power consumption.
Summary of the invention
Object of the present invention is just to provide the little burner cleaning apparatus of coke oven coke side that a kind of energy high efficiency, low cost reclaims cell-type coke oven coke side little burner flue dust.
Solution of the present invention is such:
The little burner cleaning apparatus of a kind of coke oven coke side, on furnace roof baseline, be provided with furnace roof dust blower, described furnace roof dust blower is communicated with little burner dedusting main; Under described little burner dedusting main transverse strands is located at and adds flue-gas transforming valve, vertical coal car Mo electricity road support is set up at every two adjacent little burner two ends respectively, the structure of flue-gas transforming valve between adjacent coal car Mo electricity road support is added described in formation, every two adjacent little burners share one and cover bucket type dust gathering arrester, and each bucket type dust gathering arrester that covers is communicated with little burner dedusting main with arm with flap valve respectively.
Technical scheme also comprises more specifically: described flap valve is connected with opening and closing linkage assembly, is driven open by opening and closing linkage assembly, is fallen to closing by deadweight.
Further: described opening and closing linkage assembly comprises push rod and push rod oil cylinder, described push rod be articulated with the flap valve spindle nose pulling hook and connect into swing-bar mechanism, described flap valve spindle nose connects with corresponding flap valve respectively.
Further: the direction of motion of the push rod of described opening and closing linkage assembly is parallel with coke guide direction of travel.
Further: the described bucket type dust gathering arrester that covers is arranged on directly over outside the little burner of coke side, connects into furnace stay support the structure covering bucket type dust gathering arrester with coke oven stay.
Advantage of the present invention is:
1, not only can install on the built coke oven come into operation and come into operation, synchronization implementation when being adapted at new project equally.
2, the flue dust loss problem that existing terrestrial station or coke guide vehicle-mounted coke discharging and dedusting device can not eliminate the little burner of cell-type coke oven is efficiently solved.
3, the subsequent purification of the little burner flue dust of the collection of this device is except utilizing the fly-ash separator of existing coke discharging and dedusting terrestrial station, also can utilize dry coke quenching environmental dust removal station or install the coal ground station for dust removal of spark arrester additional, without the need to autogamy fly-ash separator, thus can reduce investment outlay.
4, the dust blower of this device is arranged on platform between oven top of coke oven, than being installed on coke guide vehicle-mounted fan long service life and the little maintenance cost of fault reduces, maintenance construction is more convenient.
