Description
Technical field
The utility model is related to fixed-bed gasification furnace pressurized gasification fields, fill pressure release more particularly to a kind of novel coal lock
Energy saving buffer.
Background technology
Currently, domestic fixed bed pressured gasification stove coal process is intermittently operated, i.e., normal pressure coal lock first is added in broken coal, so
Afterwards by coal lock be pressurized to gasification furnace with pressure after, coal during coal is locked is added gasification furnace, and after coal, coal lock is let out to normal pressure again
Coal is locked to coal.In prior art, coal locks the coal after pressure release and locks gas, passes through gas holder successively and coal lock air compressor carries out pressure-raising
Afterwards, then it is incorporated to raw gas manifold.In coal locks Plenum Process, a pressurising is carried out to it first with raw gas manifold, then
Secondary pressurising is carried out using gasification furnace pressure itself.
In conjunction with operating experience for many years, coal lock fills decompression technique and there are problems that following three aspect at present：
(1) energy consumption is higher.The pressure that coal is locked gas by pressure release is let out from 3.0~4.0MPa or so to normal pressure.In Plenum Process
In, and this strand of gas is promoted to 3.0~4.0MPa by compressor from normal pressure.The process wastes a high position for pressure release coal lock gas
Can, and increase the energy consumption of compressor.
(2) cost of investment is high.After pressure release to normal pressure, the volume that unit coal locks gas expands about 30~40 times, to the rule of gas holder
The amount of inflating of mould and compressor has higher requirements, and causes project investment cost larger.
(3) stable operation of gasification furnace is influenced.In coal lock twice Plenum Process, pressed using cold change gas and gasification furnace itself
Power pressurising, be easy to cause process unit pressure oscillation and gasify inner operating fluctuation, cause process system pressure oscillation and
The outlet of still raw gas dustiness that gasifies increases, and is impacted to the stable operation of gasification furnace and downstream unit.
Utility model content
The purpose of the utility model is to overcome deficiency in the prior art, provide it is a kind of at low cost, efficient novel plus
Pressing fixed bed gasification furnace coal lock fills pressure release energy saving buffer.
This new pressurized fixed-bed gasification furnace coal lock fills pressure release energy saving buffer, including coal lock, gas holder, compressor,
Gasification furnace, buffer unit, low-pressure steam blow line, low-pressure nitrogen blow line, flushing water pipeline, sewage disposal facility and cross over pipe
Line；Coal lock connection gasification furnace and gas holder, gas holder are connected with compressor；Gasification furnace coal lock outlet is provided with buffer unit, coal is installed
Be locked into buffer unit fills blowdown line and control valve and instrument；Buffer unit upstream end be provided with low-pressure steam blow line,
Low-pressure nitrogen blow line and flushing water pipeline, buffer unit downstream low spot are provided with sewage disposal facility, and buffer unit is provided with inspection
Repair manhole.
As preferred：Buffer unit is tube container or buffering tank container.
As preferred：Unicom pipeline is set between the buffer unit of each series.
The utility model has the beneficial effects that：
1. the utility model takes full advantage of the high-lying well of coal lock pressure release gas, reduces work done during compression, reduce energy consumption.
2. the utility model avoid in existing design caused by cold change gas and gasification furnace pressurising twice process unit and
Gasification furnace pressure oscillation reduces dust drag-out, ensures entire gasification outlet pressure controllers stable operation.
3. the utility model reduces the configuration scale of complicated coal lock gas holder and coal lock air compressor system, cost of investment compared with
It is low.
4. the utility model is avoided since gas holder buffer time caused by fluctuation of operating conditions reduces in existing design, upper raising speed
Degree accelerates influence to gas holder stable operation, while reducing gas holder the possibility of raw gas is discharged and lost to superpressure in short-term.
