Coke oven loss flue dust collecting method based on a kind of coke oven loss smoke collecting device described in the utility model, bag
Include：
1) coke oven 4 normally produce when, machine Jiao both sides and top surface temperature between 70~90 DEG C, furnace wall by heat transfer,
Heat radiation and the convection current of loss high-temperature flue gas are conducted, and transfer heat to the air near furnace wall；Air near furnace wall is with temperature
Raise, density is gradually reduced, the air-flow that generation is flowed up along the sidewalls vertical of coke oven 4；The air-flow that this part flows up is swept along
The noxious fume that loss goes out from coke oven 4, and is mixed with ambient air during being gradually increasing；
2) noxious fume that loss goes out in coke oven 4 includes that the machine of the coke oven 4 Jiao both sides fire door 5, gap of tedge 8, furnace roof are coaling
Flue dust is escaped at hole 6, peephole 7, the smoke catching cover 1 that the air-flow for flowing up finally is arranged on the top of coke oven 4 is captured,
Captured flue dust is transported in outside clarifying smoke processing equipment by smoke conveying duct 2 and carries out purified treatment；

Ambient air flow direction around coke oven 4 and flow can be carried out effectively guiding and adjusting：
When the ambient air flow of the windward side of coke oven 4 runs into windproof adjusting means 3, small part air-flow is by deep bead
Air holes gas channel continue flow forward, most of air-flow is then intercepted at the outside of windproof adjusting means 3；By windproof regulation
Ambient air flow speed after device 3 will be substantially reduced, so as to effectively reduce ambient air flow be trapped to smoke catching cover 1
The influence of the loss flue dust effect of coke oven 4, improves smoke catching efficiency；
When ambient air flow is passed through by the top of smoke catching cover 1, in the case where air-flow velocity is higher, can be in coke oven
4 leeward side forms a negative pressuren zone；Negative pressure can cause the ambient air flow in the region to form air-flow vortex, so as to accelerate
Flowing, the agitation of air-flow vortex can influence smoke catching cover 1 to the trapping effect of the loss flue dust of coke oven 4；Now, coke oven 4 is leeward
The windproof adjusting means 3 of side can effectively slow down the agitation influence of air-flow vortex, it is ensured that smoke catching effect.
Air quantity adjusting mechanism, and 2 are respectively provided with the windproof adjusting means 3 of the windward side of coke oven 4 and the leeward side of coke oven 4
Individual air quantity adjusting mechanism is separately adjustable.
When carrying out the regulation of the windward side ambient air flow of coke oven 4, the ambient air flow of below wind speed 10m/s is by keeping out the wind
Mean wind speed after plate air holes gas channel is less than 2m/s.
The above, only the utility model preferably specific embodiment, but protection domain of the present utility model is not
Be confined to this, any one skilled in the art in the technical scope that the utility model is disclosed, according to this practicality
New technical scheme and its utility model design are subject to equivalent or change, should all cover in protection model of the present utility model
Within enclosing.
