Description
Technical field：
The utility model belongs to coal processing field of comprehensive utilization, is particularly well-suited to produce semi-coke by raw material of low rank coal
The dry coke quenching auxiliary discharged of the coke using upright furnace process of coking.
Background technology：
Country's semi-coke production capacity is about 86,100,000 tons at present.2012 through relevant department calculate, wherein 45,000,000 tons of Shaanxi Province,
25,300,000 tons of Xinjiang, 9,700,000 tons of the Inner Mongol, 6,100,000 tons of Ningxia.The research and development of domestic Coal Chemical Industry, designing unit start just for 2009
Be devoted to the research and development of the retorting technique of face coal, small beans and moulded coal, the newly-increased semi-coke production capacity of a few years from now on will more than 30,000,000 tons,
So the aggregated capacity of semi-coke will be more than more than 100,000,000 tons.Therefore, if do not sought new semi-coke application field, new market is expanded
The further development of semi-coke industry will be blocked.
In addition, in semi-coke production field, using shaft furnace（Upright furnace）The quenching of process of coking refers to by fervid red coke
It is cooled to the operating process for being easy to convey and store.Shaft furnace（Upright furnace）Coking finishing temperature is in 600~750 DEG C of scopes, semi-coke
Less than 250 DEG C are cooled to after quenching.Domestic semi-coke manufacturer quenching form uses water coke quenching method substantially, and water quenching is caused
Water resource waste, while the waste of the energy is also resulted in using coal gas drying course after quenching, in water quenching, the process of drying
The large quantity of exhaust gas of middle generation（The pollutants such as phenol, cyanogen）By serious pollution surrounding enviroment.
Semi-coke（Semicoke）Water extinguishing technique operation principle falls into water sealed tank for red-hot coke, while producing some vapor, water
The waste gas extinguishing technique such as coal gas.The method of the discharging of the coke has simple structure, and operation is easy, and continuity is strong, the advantages of safe.It is
Current country's shaft furnace（Upright furnace）Water quenching widely used in production (i.e. coke pushing, scrape burnt form).The method is：540 DEG C high
The red coke of temperature fall into water sealed tank it is soaking after scraped by scrapper conveyor, semi-coke is full of more than 28% moisture content by switching under destructive distillation state
Water drags for Jiao, semi-coke（Semicoke）Decompose and rupture under this kind of low temperature, small part becomes burnt mud and is deposited in quenching groove, greatly
Part coke breeze and block are burnt dried through coal gas after moisture be down to less than 13% and be delivered to that Jiao Chang classifications are outer to sell.But this kind of mode of the discharging of the coke is tight
Environmental protection, energy-saving, comprehensive utilization idea of development that country advocates have been run counter to again.
Though the semi-coke dry coke quenching auxiliary of the Patent No. 201320806780.X that our company declared on December 03rd, 2013
So solve above mentioned problem, but its discharging device for coke is mainly and is made up of gate valve, ram, lock steam valve and motor etc., according to mechanism
What happens and production client's requirement, sum up the one of this mechanism during the use in recent years of production scene
It is a little not enough：One be due in production process to the selected control inconvenience of raw material（Materials are uneven, include debris etc.）, coke pushing can be caused
Machine is blocked, and serious meeting causes burning out for controlled motor；Two is that, because the particularity and continuity of operating environment are higher, lock steam valve holds
Easily failure causes gas to leak, and need to often change part；Three is that production scene is difficult to realize remote monitoring, workman's workload compared with
Greatly, human cost is higher；Four is that power consumption is larger in production process, is unfavorable for the section of enterprise because bed rearrangement stove uses motor excessive
Can consumption reduction.Therefore the semi-coke of the upright coke oven of Patent No. 201620424171.1 was declared on May 6th, 2016 by our company
Dry coke quenching equipment, although solve above mentioned problem, but because it uses double-deck coke pushing structure, complex structure, manufacture are not only existed
The problems such as high cost, and from inside coke discharging groove scraper conveyor conveying quenching after semi-coke directly contacted with the external world, deposit
The problems such as exhaust emission environment.
