Description
Technical field
The steady mechanism of coal slurry pipeline of coal gasification apparatus, belongs to coal water slurry gasifying device.
Background technology
When coal water slurry gasifying device gasification furnace stops, the automatic valve on coal slurry burner valve gasification furnace feed-line can close automatically
Closing, the coal slurry pipeline being at this moment exported between burner valve at high-pressure coal pulp pump maintains the pressure of normal 7.0MPa when producing.Again
Before secondary startup coal slurry pump rinses coal slurry pipeline, need to change flow process and walk coal slurry return wire, owing to the backflow on return line is automatic
Being normal pressure after valve, this when, coal slurry pipeline pressure was by 7.0MPa bust to normal pressure, can cause the high vibration of coal slurry pipeline, high
Therefore pressure coal slurry pump outlet buffer double flexible pipe barrier film also often there is rupture.Affect coal gasification apparatus to run.Ask for above-mentioned
Topic, research is by realizing that the steady pressure release of coal slurry pipeline solves.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of coal gasification apparatus
The steady mechanism of coal slurry pipeline, it can be avoided that because the high-pressure coal slurry pump hose diaphragm failures causing is vibrated in coal slurry pipeline pressure release, improve
Coal gasification apparatus operation ratio, the extension device pipeline life-span.
The utility model solves its technical problem and be the technical scheme is that the pipeline of this coal gasification apparatus coal slurry is steady
Mechanism, including coal slurry groove and gasification furnace feed-line, the rear that coal slurry groove connects gasification furnace feed-line is provided with reflux pipeline, its
It is characterised by: on described reflux pipeline, be front and back provided with backflow automatic valve and backflow hand-operated valve, reflux automatic valve described and return
It is provided with a blowdown line with relief valve to described backflow hand-operated valve, described backflow automatic valve and returning between stream hand-operated valve
It is connected with the valvular exhaust line of band and waterflood-transmission line on blowdown line between stream hand-operated valve.Former on coal slurry reflux pipeline set
In respect of together backflow automatic valve and together with reflux hand-operated valve.The utility model increases moisturizing exhaust line between twice valve and lets out
Pressure pipeline.Before coal slurry pipeline pressure release, water will be full of between return wire gauge valve and hand-operated valve, then open gauge valve, due to water
Almost incompressible, at this moment coal slurry pipeline pressure varies less.Then blowdown line pressure-relief valve is driven slowly, it is achieved steadily let out
Pressure, after pressure release completes, standard-sized sheet return wire hand-operated valve prepares turn on pump clean-up line.
Described gasification furnace feed-line is provided with multiple automatic valve and hand-operated valve.
Preferably, the described relief valve on blowdown line is hand-operated valve.Relief valve is that hand-operated valve can control pressure release speed
Rate, convenient control, reduces pipeline vibration.
Preferably, the described valve on waterflood-transmission line is hand-operated valve.Rate of water injection can be controlled easily.
Preferably, the described valve on exhaust line is hand-operated valve or automatic valve.Can arrange timely while water filling
Original gas in going out reflux pipeline, it is ensured that fill water in reflux pipeline.
Compared with prior art, the beneficial effect that the steady mechanism of pipeline of coal gasification apparatus coal slurry of the present utility model is had
Fruit is: this technology solves the vibration of gasification furnace docking process mesohigh coal slurry pipeline and high-pressure coal slurry pump discharge buffer compartment film rupture
Problem, it is achieved that the steady pressure release of coal slurry pipeline.Use this technology, only need to increase by three thinner pipes on coal slurry reflux pipeline
Line, it is possible to realize.Avoid and produce because high-pressure coal slurry pump discharge diaphragm failures affects device, it also avoid coal slurry pipeline violent
Weld cracking that vibration is likely to result in, conduit saddle dislocation, the problem such as flange leakage.This technological investment saves, and processes technique simple, energy consumption
Low, without processing cost, it is easy to operation.Effectively save operating cost, coal gasifier is opened, is stopped once needing to consume raw material cost very greatly, gas
Change normal two operations of stove, can avoid every year causing gasification furnace parking about four because of high-pressure coal slurry pump discharge buffer compartment film rupture
Secondary, so the design can greatly reduce operating cost.It is easy to promote, there is significant economic benefit, decrease discharge simultaneously
And environmental pollution, there is obvious social benefit.
