Technical field
The utility model relates to length after a kind of coal press machine apart from the sedimentary scavenge unit of gas pipeline, belongs to and removes pipeline sludge processes and equipment technical field.
Background technology
In industrial production, after coke-stove gas reclaims the chemical products such as naphthalene wherein, benzene homologues, tar, ammonia by the chemical products production process, be purified and pass through the pressurization of Roots blower or centrifugal blower and send outside, the coke-stove gas of sending outside is used usually used as fuel gas or gas purification.In course of conveying, owing in coke-stove gas, itself still containing the steam such as a certain amount of naphthalene, benzene homologues, tar, along with the increase of fed distance, temperature reduces, contained organic substance just condenses into solid, is deposited in inner-walls of duct, particularly accumulates in pipe bending position or branched pipe place.These compounding substances hardness are higher, especially in cold season, pipeline and respective row hydrophone are caused to more serious obstruction, gas flow is reduced or complete blocking pipe, and it is shorter to form the cycle of stopping up, affect the normal conveying of coal gas, cause the accident when serious, bring considerable influence to normal production and environmental protection.Way commonly used is to determine the line clogging position for this reason, removes the pipeline stopped up, and carries out welded and installed after cleaning again.But remove that pipeline carries out that operation exists that investment is large, long construction period, problem that security risk is high, also will stop the conveying of coke-stove gas, have a strong impact on the normal operation that enterprise is used the subsequent handling that coke-stove gas produced.In addition when removing and blocking pipe be installed, the coal gas that coke oven produces must diffuse, cause serious environmental pollution, and face again after the use of 3～4 years and stop up and must re-start dredging after the blocking pipe dredging is normal, therefore know that by the dismounting pipeline sedimentary method has very large drawback, be badly in need of improving, to adapt to the needs of production.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of coke-stove gas conveyance conduit sediment scavenge unit, adopts this device effectively to remove the sediment formed in the coke-stove gas course of conveying, and need not carry out dismounting to conveyance conduit.
The technical scheme solved the problems of the technologies described above is:
A kind of coke-stove gas conveyance conduit sediment scavenge unit, it is comprised of ammonia vessel, ammoniacal liquor pipeline, aqua ammonia pump, water trap, ammonia vessel is connected on the coke-stove gas conveyance conduit by the ammoniacal liquor pipeline, with the spray hole of coke-stove gas conveyance conduit, be connected, on the ammoniacal liquor pipeline, aqua ammonia pump is installed, the bottom of coke-stove gas conveyance conduit is connected with a plurality of water traps, and water trap is connected with mechanical settling tank by pipeline.
Above-mentioned coke-stove gas conveyance conduit sediment scavenge unit, the spray hole of described coke-stove gas conveyance conduit is a plurality of, a plurality of spray holes are uniform along the length of coke-stove gas conveyance conduit, and the distance between adjacent spray hole is 300～500m, and the ammoniacal liquor pipeline is connected with a plurality of spray holes respectively.
The beneficial effects of the utility model are:
The utility model utilizes hot ammoniacal liquor to be dissolved rear discharge to the sediment be deposited in the coke-stove gas conveyance conduit, removed the lower deposition of the materials such as naphthalene bottom coke oven gas pipe of boiling point, the problem of having avoided gas piping to stop up, make the production of subsequent handling unaffected, reduced the incidence of production accident.The utility model has overcome traditional drawback of passing through dismounting pipeline scavenger precipitation object space method, has avoided stopping sending because of the coke-stove gas that the dismounting pipeline causes, and has guaranteed carrying out smoothly of production, and the environmental pollution caused because of bulk storage coal gas can not occur yet.Method of the present utility model is simple to operate, implementation result is good, the device used is simple, installation and maintenance and replacing are all very convenient, invest littlely, the deposit processing cost is also very low, has significant economic benefit and social benefit simultaneously, be effective alternative of at present traditional removing coke-stove gas conveyance conduit sludge processes, good popularizing value is arranged.
