Description
Technical field
The invention belongs to coal processing field of comprehensive utilization, be particularly well-suited to the dry coke quenching auxiliary adopting upright furnace process of coking to discharge of the coke for raw material production semi-coke with low rank coal.
Background technology
Current domestic semi-coke production capacity is about 86,100,000 tons.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 to be directed to the research and development of the retorting technique of face coal, little beans and moulded coal for 2009, and the newly-increased semi-coke production capacity of a few years from now on will more than 30,000,000 tons, and the aggregated capacity of such semi-coke will more than more than 100,000,000 tons.Therefore, if do not sought new semi-coke application, expand new market and will block the further development of semi-coke industry.
It addition, in semi-coke production field, adopt the quenching of shaft furnace (upright furnace) process of coking to refer to and fervid red coke be cooled to the operating process being easy to conveying and storage.Shaft furnace (upright furnace) coking finishing temperature, 600～750 DEG C of scopes, is cooled to less than 250 DEG C after semi-coke quenching.Domestic semi-coke production producer quenching form adopts water coke quenching method substantially, and water quenching causes water resource waste, after quenching, adopt the waste also resulting in the energy in coal gas drying course simultaneously, water quenching, drying process in the large quantity of exhaust gas (pollutant such as phenol, cyanogen) that produces by serious pollution surrounding enviroment.
Semi-coke (semicoke) water extinguishing technique operation principle is that red-hot coke falls into water sealed tank, simultaneously the waste gas extinguishing technique such as generating section steam, water gas.This method of the discharging of the coke has simple in construction, operates easy, and seriality is strong, safety advantages of higher.It is water quenching widely used in the production of current domestic shaft furnace (upright furnace) (i.e. coke pushing, scrape burnt form).The method is: 540 DEG C of red coke of high temperature fall into water sealed tank soaking after scraped by scrapper conveyor, semi-coke drags for Jiao more than the water of 28% moisture content by transferring under dry distilling state being full of, semi-coke (semicoke) is decomposed under this kind of low temperature and breaks, and small part becomes burnt mud and is deposited in quenching groove
In, major part coke breeze and lump coke moisture after coal gas is dried is down to less than 13% and is delivered to outside burnt field classification and sells.But this kind discharges of the coke
Mode has seriously run counter to the environmental protection that country advocates, the idea of development saved energy and reduce the cost, comprehensively utilize.
Summary of the invention
The purpose of the present invention is contemplated to provide that a kind of technique is advanced, rational in infrastructure, production efficiency is high, the semi-coke dry coke quenching auxiliary of good product quality.
The technical solution adopted in the present invention is: it includes the parts such as upright furnace, coke discharge box, coke guide, manual platform gate valve, apron conveyor and belt conveyor.Being additionally arranged spray system in the side of coke discharge box, its underpart is provided with coke guide, and the discharging opening under coke guide is provided with manual platform gate valve, is provided with the equipment of the discharging of the coke, and is provided with induced draught system on apron conveyor outlet top below discharging opening and between apron conveyor.Described spray system is to be made up of the water tank being arranged on upright furnace side and nozzle, and the lower end of nozzle is arranged on the side of coke discharge box bottom coke guide, and the other end is connected with water outlet of water tank by installing the pipeline of valve.The described equipment of the discharging of the coke is to be made up of ram and blocking valve, and ram is arranged on below the outlet of the discharging opening arranging manual platform gate valve, and blocking valve is arranged on the lower section of ram side.Described ram and blocking valve are driven by belt gear by the motor being arranged on support.
The present invention has the beneficial effects that: owing to coke discharge box is provided with spray system, after the red coke of red heat that upright furnace discharging opening is discharged enters coke discharge box, quenching injection flow rate can be controlled according to semi-coke blanking velocity, regulate the moisture of semi-coke (semicoke), spray instantaneous generation high temperature and high pressure steam and form vapor slugs, bottom discharging opening part above air barrier, substantial amounts of steam then occurs water gas reaction to carry out quenching with the red coke exchange of red heat, steam produces hydrogen with water gas reaction, effectively improves calorific value of gas.The ram that coke discharging mouth bottom is arranged and blocking valve realize uniform blowing, blocking valve lower connecting plate formula conveyer, and the semi-coke after conveying quenching is to belt conveyor, then is transported to Jiao Chang screening station classification export trade by belt feeder.The induced draught system that formula plate conveyor outlet top connects, collects a small amount of steam excessive when the discharging of the coke and waste hot gas and is delivered to cesspool.There is the advantages such as technique is advanced, rational in infrastructure, simple to operate, seriality is higher, safe and reliable, it may be achieved non-maintaining, environmental protection, energy-saving and cost-reducing purpose, semi-coke (semicoke) moisture controls in 2～8% scopes.
Below in conjunction with accompanying drawing, the invention will be further described.
