Description
Technical field
The utility model is related to coal gasification field, specifically a kind of gasifying powder coal device.
Background technology
Coal gasification process is coal or coal tar and gasifying agent（Oxygen and vapor etc.）The reaction generation oxide of carbon, hydrogen,
The process of the clean gas fuel such as methane, is the core technology and leading technology of generally acknowledged Modern Coal-based Chemical technique, and gasification furnace
It is then the core in coal gasification process technology.Entrained flow bed gasification technology is then the coal gasifying process skill generally used on a large scale at present
Art, and the gasification furnace early stage in its core using spray technique under single burners on top, but because its coal gasification scale and gasification efficiency by
To limitation, many burner air-flow bed techniques are occurred in that, i.e., many burners are vertically disposed to gasification furnace top, and material is vertically down into gas
Change in stove.Because of the increase of burner quantity, the increase of furnace flame area, the collision area increase of material and gasifying agent, so as to improve gas
Change efficiency and ability.
But there is also many deficiencies for the gasification installation：The oxygen flow of multiple process burners is carried out by an oxygen regulating valve
Regulation, just hides some dangers for for the oxygen flow balance of many burners in the design；In addition, in the fine coal delivery system based on two-phase transportation
In system, fine coal pipeline is easily fluctuated, but in the case, then must be interlocked gasification furnace and be carried out parking process；Startup burner
Still run after process burner input, during which can consume fuel gas and oxygen, increase consumption.
The content of the invention
Technical assignment of the present utility model is, there is provided a kind of gasifying powder coal device, to be somebody's turn to do for above-mentioned the deficiencies in the prior art
Device can make burner accomplish that oxygen load is consistent, and preferably protection startup burner and process burner, are prevented because of fine coal coal buret line
Fluctuate and cause gasification installation to stop, even the damage of process burner.
Technical assignment of the present utility model is realized in the following manner：Gasifying powder coal device, including startup burner and extremely
Few two process burners, startup burner connection fuelgas pipeline and oxygen pipeline, process burner connection fine coal pipeline and gasifying agent
Pipeline, the gasifying agent pipeline is made up of oxygen pipeline and steam pipe line, is characterized in that each process burner sets gasification respectively
Agent tap line and fine coal tap line.That is, the gasifying agent pipeline of each process burner is corresponded with fine coal pipeline and set, can
By adjusting the gasification agent flux of gasifying agent pipeline and the fine coal flow of fine coal pipeline, to make the gasifying agent stream of single process burner
The ratio of amount and fine coal flow is in proper range.
Further, fuel gas emptying point and high-pressure carbon dioxide can be set to blow on the fuelgas pipeline of startup burner
Sweep a little, fuel gas emptying point is arranged between fuel flow control valve and the stop valve of fuel gas first, is fed intake for startup burner
The demarcation of preceding fuel gas flow；High-pressure carbon dioxide purging point is arranged on the first stop valve of fuel gas downstream, high-pressure carbon dioxide
Gasification furnace is directly entered, the controlled atmosphere of fuelgas pipeline is exited during process burner is run for startup burner.
Two oxygen emptying points, cleaning high pressure nitrogen purging point, first can also be set on the oxygen pipeline of startup burner
Individual oxygen emptying point is arranged between startup burner oxygen regulating valve and the stop valve of oxygen second, oxygen before being fed intake for startup burner
Throughput is demarcated；Second oxygen emptying point is arranged between the stop valve of oxygen first and the stop valve of oxygen second, for opening
Atmospheric valve is opened with first oxygen emptying point simultaneously, it is ensured that oxygen is thoroughly isolated with gasification furnace after the parking of work burner；Elevated pressure nitrogen
Air-blowing, which is swept, to be a little arranged between last one of the stop valve in stokehold and oxygen air inlet.
For the ease of demarcating on valve position, the oxygen pipeline of startup burner, oxygen regulating valve is arranged on oxygen emptying point front end.
Before gasification installation prepares operation, startup burner fuel gas and oxygen can be put by fuel gas emptying point and oxygen
Null point is vented, while by the governor valve control emptying flow before emptying point, playing a part of demarcation valve position.
After startup burner puts into operation, during which can boost situation pair according to startup burner running situation and gasification installation
Process burner is put into.
Preferably, when startup burner is run to 3.0-3.6MPa, process burner proceeds by input, with utmost
Avoid synthesis gas from being vented, save expense；
Or, when startup burner is run to 1.0MPa, process burner comes into operation, to reduce startup burner run time, protection
Startup burner.
After process burner puts into operation, for the fluctuation of operating conditions of burst, the fine coal flow of manually adjustable process burner
And oxygen flow, make the ratio of gasification agent flux and fine coal flow of single process burner in the reasonable scope, control technique is burnt
Mouth head temperature protects process burner in normal range (NR)；, can be in a short time for the severe service fluctuation of burst（10 points
Within clock）Parking process is carried out to a certain process burner.Startup burner can choose whether to continue to transport according to gasifier operation situation
OK, such as running situation is stable（Such as 2 hours of even running or more）, startup burner can be stopped, while to fuel gas
Pipeline is passed through high-pressure carbon dioxide, cleaning high pressure nitrogen progress purging protection is passed through to oxygen pipeline.
Compared with prior art, gasifying powder coal device of the present utility model has beneficial effect following prominent：
（One）The gasifying agent pipeline of each process burner is corresponded with fine coal pipeline to be set, i.e., each process burner correspondence
A set of gasifying agent tap line and fine coal tap line, process burner can be gasified rapidly when operating condition is fluctuated
The proportion adjustment of agent flux and fine coal flow, makes the ratio of gasification agent flux and fine coal flow in fine coal combustion nozzle system in safe model
In enclosing, process burner is protected；, can be to relative in the case where serious problems occurs in the fine coal induction system for being easier to fluctuate
The process burner answered carries out short time parking process, and after the completion of issue handling, the process burner is put into rapidly, can avoid because
Play gasification furnace parking.
（Two）After being put into operation within the process burner short time, startup burner can be artificial according to the running situation of process burner
Parking process is judged whether to, if now process burner running status is not very good or process burner occurs to jump car, is opened
In the case that work burner does not stop also, gasification furnace is simply to be purged, without pressure release in stove, treats that furnace gas analysis takes
Coming into operation for process burner can be carried out after sample is qualified again, the time is saved, car is jumped to running time again about 30 from process burner
Minute, driving expense can be once saved for 800,000 yuan.
（Three）After process burner puts into operation, it manually can be determined whether to stop startup burner according to operating condition
Car, cleaning high pressure nitrogen of the gasifying agent pipeline after filtering is protected after it stops, fuelgas pipeline is by high-pressure carbon dioxide
Protected, startup burner gasifying agent pipeline is cut off with main system, and carries out emptying isolation, the stabilization of operation can either be ensured
Property, extend form burner service life, the waste of the energy can be avoided again, hourly rate is about 1200 yuan.
