Abstract
Disclosed is a jet stream boost device. A booster fan is arranged at the air inlet end of a smoke-guide side suction pipe, an air inlet elbow communicated with the air inlet end of the smoke-guide side suction pipe and a jet pipe communicated with the air discharge end of the smoke-guide side suction pipe are arranged on an air discharge pipe of the booster fan, the air inlet elbow is communicated with the jet pipe and provided with an air adjusting valve, and a jet pipe fairing cone is arranged in the air discharge end of the jet pipe. According to the arrangement of the jet stream boost device, an adjustable negative pressure zone is formed at the tail end of the smoke-guide side suction pipe, escape of harmful flue gas caused by the negative pressure at the pipe opening is prevented, and the defect that the emission of flue gas spilled from a coal charging hole is not up to the standard is overcome.
Description
Technical field
The utility model belongs to the jet apparatus field, is specifically related to the jet-stream wind supercharging device that the control harmful smoke escapes in the coke oven coal-charging process.
Background technology
During coke oven coal-charging, owing to the restriction of the technology of coalingging, easily produce the flue dust of the following aspects:
(1) pack into the coal charge of coking chamber displaces large quantity of air, when shove charge begins airborne oxygen also and the duff grain incomplete combustion that enters stove generate carbon black, and form black smoke.
(2) the shove charge coal contacts, heats up with the high temperature furnace wall, produces a large amount of water vapors and raw gas.
(3) fine breeze of kicking up simultaneously with above-mentioned water vapour and raw gas, and the fine breeze of taking out of during flat coal the latter stage of coalingging.
(4) raw gas that sprays because of the instantaneous obstruction in furnace roof space.
The above-mentioned all kinds of flue dust that escapes accounts for greatly in the production process 20%～30% of total fume amount in the uncontrollable discharge situation.The toxic substances such as the bismuth silicate that produces, benzopyrene account for 40%～60% of coke oven total release.At present, part producer adopts high pressure aqua ammonia (or steam) to spray and leads the cigarette technology in conjunction with the coal charger side draught pipe, enters gas main after the coking chamber burning with the flue gas importing adjacent bonds breeze phase of coalingging, to control the discharging of its objectionable impurities.System's negative pressure that above-mentioned way produces is less, and it is larger that the gas collection effect is affected by the pressure change of body of heater own, so although obtained certain effect, in the situation that the larger partial fume that still has of body of heater malleation leaks, can not realize qualified discharge.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned common high pressure aqua ammonia or vapo(u)r blasting, side draught pipe and leads the defective that the coke oven coal-charging smoke treating method of cigarette technology exists, and provides a kind of and can regulate negative pressure in the side draught pipe, effectively controls the jet-stream wind supercharging device of harmful smoke loss.
Solving the problems of the technologies described above the technical scheme that adopts is: be provided with booster fan and lead the cigarette side draught pipe at support, the air-intaking bent pipe of booster fan is arranged in the air intake of leading the cigarette side draught pipe, air outlet, the other end that one end of jet pipe is arranged on booster fan are arranged in the outlet air end of leading the cigarette side draught pipe, air-intaking bent pipe and jet pipe link, be provided with air adjusting valve in the air-intaking bent pipe, be provided with the jet pipe fiaring cone in the outlet air end of jet pipe.
The outlet air end of jet pipe of the present utility model is top-down divergent contour pipeline, and the cone angle of divergent contour pipeline is 10 °～20 °, and the cone angle beta of jet pipe fiaring cone is 20 °～60 °.
The outlet air end of jet pipe 1 of the present utility model is top-down divergent contour pipeline, and cone angle the best of divergent contour pipeline is 14 °, and cone angle beta the best of jet pipe fiaring cone 7 is 45 °.
The utility model adopts the setting of jet-stream wind supercharging device, leading the terminal adjustable negative pressure district that forms of cigarette side draught pipe, has overcome mouth of pipe negative pressure and has caused harmful smoke to escape, and fume emission defective not up to standard is overflowed in the hole of coalingging.The utlity model has reasonable in design, simple in structure, can effectively control the advantages such as harmful smoke loss, can promote the use of at coke oven.
