Description
Technical field
The present invention relates to fixed-bed gasification furnace pressurized gasification fields, and it is energy saving to fill pressure release more particularly to a kind of new coal lock
Buffer unit and method.
Background technology
At present, domestic fixed bed pressured gasification stove coal process is intermittently operated, i.e., broken coal first is added in normal pressure coal lock, so
Afterwards by coal lock be pressurized to gasification furnace with pressure after, coal during coal is locked adds in gasification furnace, and after coal, coal lock is let out to normal pressure again
Coal is locked to coal.In existing process, the coal lock gas after coal lock pressure release carries out pressure-raising by gas holder and coal lock air compressor successively
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.
With reference to 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.Pressure release from 3.0~4.0MPa or so, lets out the pressure of coal lock gas 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 add the energy consumption of compressor.
(2) cost of investment is high.After pressure release to normal pressure, the volume of unit coal lock 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 the stable operation of gasification furnace and downstream unit is impacted.
The content of the invention
The purpose of the present invention is overcoming deficiency of the prior art, a kind of new pressurized at low cost, efficient is provided and is consolidated
Fixed bed gasification furnace coal lock fills pressure release energy saving buffer and method.
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 method that this new pressurized fixed-bed gasification furnace coal lock fills pressure release energy saving buffer：When coal locks pressure release, coal lock
A pressure release first is carried out to buffer unit, when the pressure difference of coal lock and buffer unit reaches setting value, coal, which is locked to gas holder, carries out two
Secondary pressure release；When coal locks pressurising, a pressurising is carried out first with the high pressure coal lock gas of buffer unit, when the pressure of buffer unit and coal lock
When difference reaches setting value, gas holder compressed gas is recycled to carry out secondary pressurising.
The beneficial effects of the invention are as follows：
1. the present invention takes full advantage of the high-lying well of coal lock pressure release gas, reduce work done during compression, reduce energy consumption.
2. the invention avoids process unit and gasifications caused by cold change gas and gasification furnace pressurising twice in existing design
Furnace pressure fluctuation reduces dust drag-out, ensures entire gasification outlet pressure controllers stable operation.
3. the present invention reduces the configuration scale of complicated coal lock gas holder and coal lock air compressor system, cost of investment is relatively low.
4. the invention avoids, since gas holder buffer time caused by fluctuation of operating conditions reduces, the rate of climb adds in existing design
Soon to the influence of gas holder stable operation, while reduce gas holder superpressure discharge in short-term and lose the possibility of raw gas.
Description of the drawings
Fig. 1 is the process flow chart of the present invention；
Fig. 2 is the structure diagram of the present invention.
Reference sign：Coal lock 1, gas holder 2, compressor 3, gasification furnace 4, buffer unit 5, low-pressure steam blow line 6,
Low-pressure nitrogen blow line 7, flushing water pipeline 8, sewage disposal facility 9, unicom pipeline 10.
Specific embodiment
The present invention is described further with reference to embodiment.The explanation of following embodiments is only intended to help to understand this
Invention.It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, also
Can to the present invention some improvement and modification can also be carried out, these improvement and modification also fall into the protection domain of the claims in the present invention
It is interior.
As shown in Figure 1, 2, the new pressurized fixed-bed gasification furnace coal lock, which fills pressure release energy saving buffer, includes：Coal lock 1,
