Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
The structure of the cokery of the embodiment of the invention is shown in Fig. 1～4, and the cokery of present embodiment by 20-40 hole coking chamber 1 and combustion chamber 2 alternately.Combustion chamber 2 is than more than 1 one of coking chambers.In the combustion chamber 2 and coking chamber 1 top be provided with furnace roof 6, be provided with a plurality of grooves 4 at furnace roof 6 positions, be used for cleaning, observation, thermometric and pressure measurement to furnace roof, be provided with also that coking chamber pressure regulates mouthfuls 5, furnace roof air distribution outlet 3.Be provided with furnace roof tie rod and spring in length and breadth on furnace roof 6 tops, between groove 4 and furnace roof air distribution outlet 3, be provided with coal gas targeting port 15, on the partition wall between coking chamber 1 and the combustion chamber 2, also be provided with coal gas targeting port 15.Be provided with hot road 9 of overhead air bound and the heat insulation road 10 of following air at furnace bottom 17 positions.Be provided with burner 14 under 4 mixing flues altogether in the mechanical coke both sides of mixing flue 13 positions, mechanical coke both sides center partition 18 divides mixing flue 13 and furnace bottom flue 11 to be divided into machine, burnt two portions.Machine, burnt two-part furnace bottom divide flue 11 to establish four outlets altogether.Establish four branch flues at this outlet position and regulate plate 8 automatically, be provided with four branch flue portholes 12 in end over against four outlets.Two ends at a coke oven also are provided with left and right headwall 7 usually, and the furnace retaining ironware comprises furnace stay 19 and fire door 20 (fire door 20 is provided with and beats knife-edge, firedoor frame, protecting sheet), and the bed rearrangement coke oven is supported by coke oven heat resistance concrete substrate 21.
The height of the coking chamber 1 of the stamping clean recovery of heat vertical coke oven in this example is 3200-5600mm, and width is 450-600mm.
Above-mentioned cokery in the course of the work, coal gas enters combustion chamber 2 from coking chamber 1 at twice by coal gas targeting port 15.And furnace roof air distribution outlet 3 disposable the enter combustion chambers of air from furnace roof 6.Wherein, the raw gas that coal gas targeting port from furnace roof 6 15 imports is lining promoting the circulation of qi and outer promoting the circulation of qi, and the raw gas of coal gas targeting port 15 importings from the partition wall of coking chamber 1 and combustion chamber 2 is outer promoting the circulation of qi.Combustion chamber 2 is lower than coking chamber 1, has constituted the coke oven heat levels.Such mode helps elongating combustion flame, reduces coking chamber 1 headspace temperature, enlarged the coking chamber volume, solved smoothly the coke oven height to the uneven problem of heating.
Coking chamber pressure in furnace roof 6 is regulated mouth 5, can regulate the pressure in the coking chamber 1, and can regulate the pressure of each flue, and the coal gas of coal gas targeting port 15 distributes.Have the knife-edge of beaing, firedoor frame, protecting sheet on the fire door 20, the stopping property that this has guaranteed coking chamber 1 can prevent that from there is a small amount of coke burning phenomenon at coking later stage both sides fire door place.
The utility model is established mechanical coke both sides center partition 18 17 of furnace bottoms, and furnace bottom divides 11 of flues to be divided into two of mechanical cokes like this, and four flue outlets help improving the temperature of mechanical coke dual-side portion combustion exhaust like this, reduce the temperature of middle part; Reduce the coke oven production capacity under the situation of or coal source anxiety unsalable and to discharge flue gas up to standard at coke.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
