More specifically, illustrate with following specific embodiment:
As a example by 5.5 meters of coke ovens (model: HXDK55-08F), for side dress, twinflue, coke-stove gas heating, lower spray, give up
Gas circulation, complex thermal coke.
Every coke oven mainly by: coke oven base, regenerator 7, chute district 6, carbonization chamber 5, combustor, furnace roof district, point flue,
Main chimney flue and chimney etc. form, and its structural dimensions is as shown in the table:
Table one
Wherein, carbonization chamber 5: take briquette in and carry out the place of dry distilling.The size of its capacity and how many decision coke ovens of quantity
Production capacity and heating cycle.
Combustor: also referred to as flue, is the furnace chamber providing thermal source to carbonization chamber 5, is positioned at carbonization chamber 5 both sides, so often
The combustor always more than the quantity of carbonization chamber 5 one of seat coke oven.
Regenerator 7: be positioned at the bottom of carbonization chamber 5, Main Function is to utilize indoor checker brick, reclaim when declining from
The heat of chute waste gas, to the air preheat entering flue during rising.Additionally the effect of the double-edged fine-toothed comb brick 3 of regenerator 7 bottom is
The air distribution of flue will be entered uniformly, and keep inside and outside pressure roughly the same.Quantity many one than combustor.
Chute district 6: between combustor and regenerator 7, for both passages, can provide to combustor after preheating
Air, can derive again the waste gas that combustor produces.
Technological process after improvement
1, poor gas flow process
Carry out poor gas heating coke oven poor gas to be incorporated to poor gas main pipeline pass through through poor gas heating coke oven pressurizing point
Glasses valve on coke oven poor gas main pipeline, regulation turnover panel enter cokery side and are in charge of, and are automatically adjusted electrodynamic valve, flow through cokery side
Meter, plus-minus cock, orifice plate box, waste gas valve connecting tube, ascending air waste gas valve, bottom flue 4, double-edged fine-toothed comb brick 3, coal gas
The air mixed combustion that regenerator 7, coal gas chute and air chute come, it is contemplated that the meager coal occurred because of poor gas heating coke oven
Gas calorific value is low or poor gas not enough in the case of on original coke-stove gas supervisor, devise coke-oven coal style enter pipe as should
Anxious standby.
2, air flow process
Through ascending air waste gas valve, air poultry hot cell bottom flue 4, double-edged fine-toothed comb brick 3, air regenerator 7, air chute with
The coal gas mixed combustion that coal gas chute mouth comes.
3, waste gas flow process
A waste gas part (in a large number) after burning is through crossing over hole, chute, regenerator 7, double-edged fine-toothed comb brick 3, bottom flue 4, lower sending down the abnormal ascending QI
Stream waste gas valve, cokery side divide flue, cokery side to divide flue turnover panel, main chimney flue, main chimney flue turnover panel to discharge from chimney, another portion
Divide and supplement air through circulation port entrance ascending air on a small quantity.
To sum up, the present invention is to utilize poor gas heating coke oven poor quality coal gas to instead of high-quality coke-stove gas, by producing
It was verified that substitute coke-stove gas economic benefits with poor gas heating coke-oven gas, current burnt the situation is tense
In the case of for more preferable cost efficiency, economize on resources, improve environmental quality, solve a great problem in industry, for coal tar
Change deep processing development and bring new opportunity.The novel device of Jiujiang coal accumulating company limited research and development, through after a while
Use, achieve the effect that comparison is good, can greatly reduce cost, coke-stove gas furnace temperature need not be blended and can reach the mark of regulation
Quasi-temperature, as long as operating from secure context, safe and reliable, it is truly realized high-quality, low consumption, efficient effect.
Last it is noted that various embodiments above is only in order to illustrate technical scheme, it is not intended to limit;To the greatest extent
The present invention has been described in detail by pipe with reference to foregoing embodiments, it will be understood by those within the art that: it depends on
So the technical scheme described in foregoing embodiments can be modified, or the most some or all of technical characteristic is entered
Row equivalent;And these amendments or replacement, do not make the essence of appropriate technical solution depart from various embodiments of the present invention technology
The scope of scheme.
