The coke quenching unit can achieve the purposes of saving water and avoiding pollution and also attain semicoke products with better quality.
Description
Technical field
The utility model relates to a kind of coke quenching auxiliary, relates in particular to a kind of recirculated water of closed and the coke quenching auxiliary that spray is used in combination.
Background technology
Low-rank coal is meant the coal that degree of coalification is lower, comprises sticking coal and bottle coal etc. in brown coal, long-flame coal, the weakly caking coal, 1/2, and low-rank coal has huge reserves and higher economic value in China.Low temperature pyrogenation produced corresponding product during the low-rank coal of exploiting out need be passed through, middle low temperature pyrogenation is meant low-rank coal is placed under the atmosphere of secluding air, utilize heating medium directly or indirectly low-rank coal to be heated, heat whole temperature control between 500 ℃～900 ℃, output object comprises semicoke, gas coal gas and products such as liquid is low, coal-tar middle oil.
In the product that middle low temperature pyrogenation low-rank coal obtains, semicoke is a kind of work in-process solid-state and that still need to carry out quenching that are.In existing quenching technology, it is a kind of method commonly used that water drags for Jiao, and the upright furnace coking chamber of this method is divided into preheating section, heating zone, cooling section from top to bottom, is provided with the combustion chamber in the heating zone both sides of coking chamber.The lump coal that is added by the coking chamber top moves from top to bottom, and at preheating section, lump coal is heated to about 350 ℃, in heating zone, lump coal (granularity 〉=20mm) be heated to about 800 ℃, and be semicoke by charing.The semicoke of red heat continues descending, and enters the coke quenching pool cooling, send Jiao Chang after being pulled out from the coke quenching pool bottom by the scraper plate machine.But this method have water loss big, pollute high, semicoke product moisture height, winter easy freezing, shortcoming such as second-rate.
Summary of the invention
The water loss that exists in existing quenching technology is big, pollution is high, the moisture height of semicoke product in order to solve for the utility model, and second-rate problem provides a kind of coke quenching auxiliary, comprising:
Interior spray equipment is arranged on the front portion in the quenching stove, is used for the semicoke of the red heat state in the quenching stove is sprayed the waste water cooling, and described waste water is the waste water that produces in the coking;
The quenching stove is used for the semicoke with the red heat state of inside, carries out quenching by interior spray equipment, and the quenching waste gas that produces in the quenching process is flowed to incinerator;
Incinerator is used for the quenching stove is burned at the quenching waste gas that the quenching process produces.
By technique scheme as can be seen, the utility model is by using the waste water that produces in the coking to the cooling of spraying water of the semicoke of red heat state, and with the waste-gas burning that produces in the process of cooling, reach water saving and free of contamination purpose, and can access quality semicoke product preferably.
Description of drawings
Fig. 1 is the structural representation of the coke quenching auxiliary that provides of embodiment of the present utility model.
Embodiment
This embodiment provides a kind of coke quenching auxiliary, as shown in Figure 1, spray equipment 1, quenching stove 2 and incinerator 3 in specifically comprising, interior spray equipment 1 is arranged on the front portion in the quenching stove 2, be used for the semicoke of the red heat state in the quenching stove 2 is sprayed the waste water cooling, described waste water is the waste water that produces in the coking; Quenching stove 2 is used for the semicoke with the red heat state of inside, carries out quenching by interior spray equipment 1, and the quenching waste gas that produces in the quenching process is flowed to incinerator 3; Incinerator 3 is used for quenching stove 2 is burned at the quenching waste gas that the quenching process produces.
Quenching stove 2 can adopt closed structure, at first the semicoke of red heat state (this moment, the temperature of semicoke of red heat state was about 600 ℃～900 ℃) is directly sprayed cooling with the interior spray equipment 1 of quenching stove 2 inside, and then cool off indirectly with outer spray equipment 4,5.The waste water that interior spray equipment 1 is sprayed can adopt the waste water that produces in the coking, and the semicoke of 1 pair of red heat state of the interior spray equipment of process directly sprays, and the temperature of the semicoke of red heat state is reduced to about 300 ℃～400 ℃.
Further, can use indirect refrigerative mode to the semicoke that temperature is reduced to about 300 ℃～400 ℃, spray equipment 4 outside the upper back of quenching stove 2 is provided with, and are used for the cooling of advancing to semicoke, and the semicoke temperature is dropped to below 100 ℃; Circulating water pool 5 is arranged on the rear lower of quenching stove 2, is used to collect the spray water of outer spray equipment 4, and described spray water is offered outer spray equipment 4, to reach the purpose of water saving.
The quenching waste gas that produces in the quenching process can be delivered directly in the incinerator 3 and burn, owing to comprised the organism that the waste water that produces in the coking and quenching process produce in the quenching waste gas, therefore burning process decomposes organism fully, reaches the purpose of environmental protection.In addition, the hot waste gas that incinerator can also be produced in burning process is used for the dried feed coal.
This embodiment is the coke quenching auxiliary that the multiplexing and inside and outside spraying technique of a kind of sewage of closed combines, and has following characteristics:
1. cost of investment is low, and operational path is reasonable;
2. adopt the waste water quenching in high temperature section, can effectively decompose the organism in the waste water, waste gas and coke quenching steam enter roasting kiln together and burn, and organism perfect combustion is decomposed, and reach environmental requirement;
3. outer spray adopts recirculated water, the MIN quenching water yield that reduced;
4. quenching moisture is controlled, and the semicoke quality is secure;
5. technological process is easy to control, and is simple to operate.
Therefore, the technical scheme that provides by this embodiment had both reached water saving and the free of contamination purpose of wastewater treatment, can also obtain quality semicoke product preferably.
The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
