Abstract
A decompression maintenance device for a rotary sealing valve in coke dry quenching belongs to the technical field of coking devices, and is used for decompression maintenance of the jammed rotary sealing valve without production breaks. The device adopts the technical scheme that 4 to 8 branch decompression pipelines and a main decompression pipeline are included, wherein one end of each branch decompression pipeline is connected with the outer wall of a middle chute, and the other ends of the branch decompression pipelines are all connected to one end of the main decompression pipeline; the other end of the main decompression pipeline is connected with a main coke extraction and dust collection pipeline; and a stop valve is mounted on the main decompression pipeline. Through the adoption of the structure, the decompression pipelines can be used for decompression when the rotary sealing valve is jammed, so that an environment of slightly negative pressure is created at the rotary sealing valve. Therefore, the jamming of the rotary sealing valve can be solved without the threat on the safety of the overhauling personnel and the shutdown of a coke dry quenching circulating fan and a turbonator, which can ensure a stable coke dry quenching production, prolong the service life of equipment and guarantee the personal safety of the overhauling personnel.
Description
Technical field
The utility model relates to a kind of breaks in production that need not can handle the get stuck device of fault of rotary seal valve, belongs to the coker technical field.
Background technology:
Dry coke quenching is to adopt rare gas element with a kind of coke quenching method of red burnt cooling refrigerative.In the dry coke quenching process, red Jiao packs into from the dried furnace roof portion of putting out, the low temperature rare gas element blasts dried putting out in the red burnt layer of stove cooling section by recirculation blower, absorb red burnt sensible heat, cooled coke is discharged from the dried furnace bottom that puts out, carry out heat exchange through the chute district from dried high temperature inert gas that ring shape flue the comes out coke dry quenching boiler of flowing through that puts out, boiler produces steam, and cooled rare gas element blasts the dried stove that puts out again by blower fan and recycles.
The cold burnt device for transferring of dry coke quenching is by the coke discharging device and transport burnt belt and form.The coke discharging device comprises equipment such as maintenance bulkhgead gate, vibro-feeder, rotary seal valve, control of dust pipeline, automatic lubricating device and coke discharging chute.The coke discharging device is positioned at dried bottom of putting out stove, will put out the coke that furnace bottom is cooled to below 200 ℃ and discharge continuously through dried.Cooled coke is delivered to rotary seal valve through vibro-feeder by the amount of setting by bulkhgead gate; The rotary seal valve is discharged the coke successive under allowing the dried situation of putting out rare gas element small leakage in the stove.The coke of discharging drops on the rubber conveyer through the coke discharging chute to be exported.
Putting out in the process of adorning the red heat coke in the stove to dried, might cause the rotary seal valve of coke discharging system the fault that gets stuck to occur owing to contain foreign matter in the dried coke that puts out in the stove.Foreign matter comprises blocky graphite that coking by coke oven produces, leads residual of burnt grid, the liner plate of pack into burnt jar liner plate, the hopper of packing into and backplate, iron wire and iron rod etc., the dried cracked brick body in the stove etc. that puts out.Above foreign matter is when draining into the rotary seal valve, and very easily the flabellum with rotary valve blocks, and causes rotary valve motor overcurrent protection to shut down, and occurs the rotary valve fault alarm that gets stuck simultaneously.More than can cause the chain parking of coke discharging system, vibro-feeder, rotary seal valve, belt can stop successively.At present, get rid of this fault and want breaks in production, recirculation blower, the turbo-generator of dry coke quenching is out of service, open rotary valve top manhole, by the serviceman institute's card foreign matter is taken out.Cause dry quenching circulating fan, turbo-generator frequent shutdown thus; it is dried that to put out in the stove temperature fluctuation big; can make in brick body and the stove refractory materials cracked, come off; not only have a strong impact on the stably manufactured of dry coke quenching; and can cause damage to production unit; greatly reduction of service life, cause the tremendous economic loss.And when the serviceman opened manhole, the toxicity of the recycle gas that overflows and in the malleation at rotary valve position all can cause hazard to person to it.Simultaneously, the toxic gas that enters in the atmosphere also can cause topsoil, and the environmental pollution that causes can't be estimated.
