Compared with prior art the beneficial effect of the utility model is: because the pure oxygen surge tank is established import, the automatic regulating valve that is used to regulate pure oxygen pressure is established in the import of pure oxygen surge tank, and the outlet of pure oxygen surge tank is communicated with the import of oxygen enrichment surge tank through connecting pipeline; The oxygen enrichment surge tank is communicated with gas blower; The outlet of oxygen enrichment surge tank is communicated with the mixing and buffering jar through connecting pipeline, and the mixing and buffering jar is communicated with the furnace bottom import of Gas-making Furnace through connecting pipeline, and the outlet of Gas-making Furnace is communicated with the import of waste heat boiler through connecting pipeline; The import of waste heat boiler is communicated with scrubber tower through connecting pipeline; Adopt oxygen enrichment upstriker continuous gasification method that bituminous coal is burnt, prepare qualified synthetic gas, and in gas-making process, do not need emptying; Can not pollute air; Through tolerance and traditional tolerance that can improve 20%-25% of comparing that this equipment produces, up temperature out can be controlled in 550 degrees centigrade, and the carry over of working off one's feeling vent one's spleen is less; Reduce greatly the washing away of pipeline, reduce recirculated water and pollute.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Referring to Fig. 1; Gas equipment is combined in a kind of bituminous coal gas preparation, comprises connecting pipeline, pure oxygen surge tank 1, oxygen enrichment surge tank 2, mixing and buffering jar 3, Gas-making Furnace 4, waste heat boiler 6 and scrubber tower 9, and pure oxygen surge tank 1 is established import; The automatic regulating valve 10 that is used to regulate pure oxygen pressure is established in the import of pure oxygen surge tank 1; The outlet of pure oxygen surge tank 1 is communicated with the import of oxygen enrichment surge tank 2 through connecting pipeline, and oxygen enrichment surge tank 2 is communicated with gas blower, and the outlet of oxygen enrichment surge tank 2 is communicated with mixing and buffering jar 3 through connecting pipeline; Mixing and buffering jar 3 is communicated with the furnace bottom import of Gas-making Furnace 4 through connecting pipeline; Gas-making Furnace 6 is communicated with Gas-making Furnace drum 5, and the outlet of Gas-making Furnace 4 is communicated with the import of waste heat boiler 6 through connecting pipeline, and through exhaust gas boiler 6 is communicated with through exhaust gas boiler drum 7; The import of waste heat boiler 6 is communicated with scrubber tower 9 through connecting pipeline, is provided with coal gas main valve 8 between waste heat boiler 6 and the scrubber tower 9.
Concrete steps are following:
Air gets into pure oxygen surge tank 1 after coming pure oxygen to regulate pressure through automatic regulating valve 10, and output pressure stable oxygen gets into oxygen enrichment surge tank 2; Come air mixed with gas blower, oxygen-rich concentration is 35-45%, and oxygen enrichment gets into mixing and buffering jar 3 through connecting pipeline; After a certain amount of steam from the steam buffer jar, get into from the furnace bottom of Gas-making Furnace 4, in Gas-making Furnace 4, react with the bituminous coal generating gasification; The coal gas that produces gets into waste heat boiler 6, produces superheated vapour, and gas temperature drops to 200 deg.c; Get into scrubber tower 9 through coal gas main valve 8, directly spray cooling and washing coal ash and tar, get into refrigerator then with recirculated water.
From the above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
