Description

Gas compression pump bleeding device in parallel
Technical field
The present invention relates to gas compression pump service technique field, more particularly to a kind of gas compression pump bleeding device in parallel.
Background technology
At present the main body running device of coke-oven plant's prepared from benzene and hydrogen hydrogen system using more parallel runnings reciprocating type coal Air compressor, raw coke oven gas by an inlet manifold respectively enter every gas compression pump after multi-stage compression by After 0.1MPa is compressed to 1.9MPa, flowed out by an exhaust main, the air inlet pipe into gas compression pump is equipped with into gas control Valve and air intake filter processed, flow out gas compression pump is respectively equipped with gas exhausting valve and check-valves, the fuselage of gas compression pump Top is respectively equipped with diffuse channel and diffuses house steward's connection heel row toward air by one, diffuses house steward outlet and is provided with spark arrester and coal Gas concentration monitoring probe, in existing design, the diffusion system pipeline of gas compression pump is welding structure, with diffusing house steward All the time it is in connected state.
Although above-mentioned design of diffusing ensure that the safe and reliable of pipeline, many ask is brought in the system operation of reality Topic.Illustrated below so that gas compression pump is three as an example, first, three coal press machines after continuously running for a long time, Filler, which can progressively occur leaking and be imported by diffuse channel, at one-level cylinder and secondary cylinder diffuses house steward, therefore diffuses house steward The gas concentration of outlet monitoring can gradually rise, but because three gas compression pumps share welded diffusion system pipeline, Intermediate link is uncontrollable, therefore can not judge which platform gas compression pump leakage whole movement system is, can only be by shutting down two Platform, a method for carrying out the test of rewind machine is operated to judge, cause the frequent startup-shutdown of equipment and with risk.It is secondly as every Compressor has cylinder filler at two and is provided with corresponding exhaust stack, even if judging which compressor is let out by the above method Leakage, welded exhaust stack also cause operating personnel can not accurately judge the accurate location of packing leaking.Also, due to production Continuity is needed, and whole compressor assembly maintenance is run well using two, the maintenance model that a maintenance down is carried out by platform, Because the diffuse channel of welding can not take out stifled blind plate, once having leakage at two gas compression pump fillers of operating, house steward is diffused The coal gas of middle leakage can pour in down a chimney the compressor into maintenance, cause computer room gas concentration exceeded, maintenance can not be normally carried out.
