Description
Technical field
The utility model relates to a kind of metallurgical refrigerating unit, a kind of specifically coke oven cyclic ammonia water flusher.
Background technology
Coke oven cyclic ammonia water spray processing is as follows: the hot ammoniacal liquor that will be satisfied certain pressure and temperature by later process product operation is delivered to each nozzle of coke oven furnace roof effuser (effuser is a steel work) by pipeline and is sprayed, and more than 800 coal gas of tiding over a lean year that produce when reaching the coke oven ordinary production are cooled to purpose about 82 degree.Existing coke oven cyclic ammonia water flusher as shown in Figure 1, comprise two remained ammonia grooves 1 and 2, two ammoniacal liquor recycle pumps 3 and 4, two coke oven furnace roof effusers 5 and 6, article two, rising main 10 and 11, tensimeter and valve, effuser is provided with nozzle 9,1# coke oven furnace roof effuser 5 links to each other with 1# rising main 10,2# coke oven furnace roof effuser 6 links to each other with 2# rising main 11, hot ammoniacal liquor 1# remained ammonia groove 1 and 2# remained ammonia groove 2 splendid attires, 1# remained ammonia groove 1 and 2# remained ammonia groove 2 bottom pipe connection, and link to each other with the inlet pipeline of 1# ammoniacal liquor recycle pump 3 by one tunnel house steward with 2# ammoniacal liquor recycle pump 4, the outlet of 1# ammoniacal liquor recycle pump 3 and 2# ammoniacal liquor recycle pump 4 links to each other with the import of 1# coke oven furnace roof effuser 5 with 2# coke oven furnace roof effuser 6 by one tunnel house steward, spray by the nozzle 9 on 1# coke oven furnace roof effuser 5 and the 2# coke oven furnace roof effuser 6, all be provided with valve on each pipeline, the correlative flow tensimeter is installed in remarkable position, is convenient to observed and recorded.
When change product operation is improper, also promptly working as cyclic ammonia water pump 3 and 4 breaks down, when hot ammoniacal liquor stops supplying, available technology adopting is drawn one road pipeline with service water by the both sides of coke oven furnace roof effuser 5 and 6, directly do not send into effuser, make the effuser cooling protect the purpose of producing to reach by nozzle 9.The influence that brings like this is: under improper situation, the raw gas cooling performance is poor, because every section effuser length has about 30 meters, send normal-temperature water to enter effuser from a side and causes in the effuser temperature contrast big, produces to be difficult to control.Long as fault-time, occur effuser easily and bring the serious consequence of effuser distortion because of temperature variation, it is influenced to cause coke oven to be produced.
Summary of the invention
Technical problem to be solved in the utility model is: at the shortcoming that above prior art exists, propose a kind of can the sprinkling at cyclic ammonia water and protect effuser equipment under the improper situation and keep the coke oven cyclic ammonia water flusher that coke oven is produced.
The technical scheme that the utility model solves above technical problem is:
Coke oven cyclic ammonia water flusher, comprise remained ammonia groove, ammoniacal liquor recycle pump, coke oven furnace roof effuser and rising main, effuser is provided with nozzle, effuser links to each other with rising main, remained ammonia groove bottom links to each other with the ammoniacal liquor inlet of circulating pump by pipeline, the ammoniacal liquor outlet of circulating pump links to each other by the import of pipeline with coke oven furnace roof effuser, and the pipeline that the remained ammonia groove links to each other with the ammoniacal liquor recycle pump joins by one road pipeline and rising main, is provided with valve on this road pipeline.
When fault appears in the cyclic ammonia water pump, with the total outlet conduit valve closes of the ammoniacal liquor of former remained ammonia groove, prevent aqueous reflux, open rising main short circuit valve, because the pipeline that the remained ammonia groove links to each other with the ammoniacal liquor recycle pump joins by one road pipeline and rising main, the service water of 1-2 kilogram can be introduced ammoniacal liquor sprinkling pipeline and carry out the service water sprinkling, to solve the purpose of cooling down high-temperature raw gas.
The utility model has the advantages that: the utility model sprays piping system by up service water is introduced cyclic ammonia water, kept basic coke oven operating mode, ensured that effuser equipment is not subjected to big influence, effectively ensured the coke oven collecting main works better, ensureing particularly that effuser equipment is indeformable scraps, and has prolonged the work-ing life of coke oven furnace roof equipment.The utility model guarantees coke oven ordinary production rhythm, stablizes coke oven production, provides quality guaranteed high grade coke for the next procedure blast furnace, creates high level to blast furnace and gives security.

Embodiment
Embodiment one
The connection of present embodiment as shown in Figure 2, a kind of coke oven cyclic ammonia water flusher, comprise 1# remained ammonia groove 1,2# remained ammonia groove 2,1# ammoniacal liquor recycle pump 3,2# ammoniacal liquor recycle pump 4,1# coke oven furnace roof effuser 5,2# coke oven furnace roof effuser 6,1# rising main 10 and 2# rising main 11,1# coke oven furnace roof effuser 5 links to each other with 1# rising main 10,2# coke oven furnace roof effuser 6 links to each other with 2# rising main 11,1# remained ammonia groove 1 and 2# remained ammonia groove 2 bottom pipe connection, and link to each other with the inlet pipeline of 1# ammoniacal liquor recycle pump 3 by one tunnel house steward with 2# ammoniacal liquor recycle pump 4, the outlet of 1# ammoniacal liquor recycle pump 3 and 2# ammoniacal liquor recycle pump 4 links to each other with the import of 1# coke oven furnace roof effuser 5 with 2# coke oven furnace roof effuser 6 by one tunnel house steward 12, spray by the nozzle 9 on 1# coke oven furnace roof effuser 5 and the 2# coke oven furnace roof effuser 6, all be provided with valve on each pipeline, the correlative flow tensimeter is installed in remarkable position, is convenient to observed and recorded.In 1# rising main 10 and 2# rising main 11, have at least one to join with house steward 12 by pipeline 13, pipeline 13 is provided with valve 8.The pipeline that 1# rising main 10 links to each other with valve 8 is provided with tensimeter 7.
