Description
Technical field
The utility model relates to a kind of static bed gas making furnace five step and prepares inert gas plant, belongs to intermittent type static bed gas making furnace technical field.
Background technology
China take coal as the country of main energy sources, also account for about 70% of China at present, and this block cost of consumption of power coal accounts for about 60% of ammonia cost with the enterprise of fixed bed gasifier block coal synthesis ammonia, methanol feedstock gas.
At present, existing static bed gas making furnace three step manually rare gas element processed only do blowing up emptying, blowing emptying and blowing air (title noble gas) replace three steps, can cause trip temperature high, consume that high, indifferent gas qualification rate is low produces time long, dangerous, the problem such as personnel labor intensity is large.
Utility model content
For solving the technical problem that prior art exists, it is simple that the utility model provides a kind of structure, easy to use, and upper trip temperature is low, it is low to consume, operating safety, static bed gas making furnace five step that effectively reduces personnel labor intensity prepare inert gas plant.
For achieving the above object, the technical scheme that the utility model adopts is that static bed gas making furnace five step prepares inert gas plant, comprise: gas furnace and fly-ash separator, the top of described gas furnace is connected with fly-ash separator by epithelium healing, described dust remover roof is provided with blowing air blowdown piping and blowing up pipeline, the bottom of described gas furnace is provided with blowing down pipeline, described blowing up pipeline is connected with gas main respectively with blowing down pipeline, described gas main is connected with dry type water seal, described blowing up pipeline is provided with blowing up gas valve, blowing down pipeline is provided with blowing down gas valve, gas main is provided with coal gas main valve, the front end of described blowing down gas valve is also provided with blowing down blowdown piping, described blowing down blowdown piping is provided with blowing down coal gas blow-off valve.
Compared with prior art, the utility model has following technique effect: the utility model is simple and reasonable for structure, trip temperature in reduction, prevents from burning out equipment, reduce gas and take sensible heat out of, and the labour intensity effectively reducing feed coal consumption, reduce security risk, reduce personnel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, static bed gas making furnace five step prepares inert gas plant, comprise: gas furnace 1 and fly-ash separator 2, the top of gas furnace 1 is connected with fly-ash separator 2 by epithelium healing 3, fly-ash separator 2 top is provided with blowing air blowdown piping 5 and blowing up pipeline 6, the bottom of gas furnace 1 is provided with blowing down pipeline 7, blowing up pipeline 6 is connected with gas main 8 respectively with blowing down pipeline 7, gas main 8 is connected with dry type water seal 4, blowing up pipeline 6 is provided with blowing up gas valve 9, blowing down pipeline 7 is provided with blowing down gas valve 10, gas main 8 is provided with coal gas main valve 11, the front end of blowing down gas valve 10 is also provided with blowing down blowdown piping 12, blowing down blowdown piping 12 is provided with blowing down coal gas blow-off valve 13.
In actual use, oxygenation air and superheated vapour, interval or be mixed into gas furnace, blows off double teacher respectively through blowing emptying, blowing up, blowing down, secondary blowing up, air, and the oxygen in scorching hot charcoal and oxygenation air and steam reaction generate semi-water gas for synthetic ammonia.
Blowing emptying: the pure oxygen divided from sky and air are made into finite concentration (oxygenation air in oxygenation gas blower, enter gas furnace, carbon in oxygenation air and gas furnace reacts and generates high temperature blowing air, the sedimentation in fly-ash separator of high temperature blowing air entrained solid particle, High Temperature Gas carries out emptying through blowing air blowdown piping.
Blowing up: oxygenation air and low-pressure superheated steam mixing, gas furnace bottom portion is entered after mixing, carbon in oxygenation air, steam and gas furnace reacts the coal gas of high temperature generated and enters coal gas waste heat boiler through fly-ash separator, blowing up pipeline, blowing up gas valve, gas main, dry type water seal, reclaim the laggard scrubber tower of sensible heat, through washing, dedusting, cooling, coal gas enters gas holder.
Blowing down: oxygenation air and low-pressure superheated steam mixing, top, gas furnace bottom portion is entered after mixing, carbon in oxygenation air, steam and gas furnace reacts the coal gas of high temperature generated and enters coal gas waste heat boiler through blowing down pipeline, blowing down gas valve, dry type water seal, gas main, dry type water seal, reclaim the laggard scrubber tower of sensible heat, through washing, dedusting, cooling, coal gas enters gas holder.
Secondary blowing up: identical with blowing up principle.
Air blows off: identical with blowing emptying.
On blowing down pipeline, be wherein provided with blowing down blowdown piping and blowing down coal gas blow-off valve, when making lazy technique, close blowing down gas valve, opening blowing down coal gas blow-off valve, carry out emptying; When normally producing, closing blowing down coal gas blow-off valve, opening blowing down gas valve, proceed lower blow moulding.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should wrap within the scope of the utility model.
