The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done to describe in detail.
In conjunction with the thermal storage type oxygen-enriched combusting device shown in Fig. 1-4, it comprises two thermal storage type oxygen-enriched combusting devices that are provided with about branch, described each burner comprises accumulation of heat (heat exchange) chamber 1, be arranged on heat storage 5 in described accumulation of heat (heat exchange) chamber 1 and the mist conduit 6 that is positioned at described heat storage center, around described heat storage 5, be surrounded by thermal insulation layer 15, be connected with burner tip 7 in accumulation of heat (heat exchange) chamber 1 of an end of described heat storage 5, the center of described burner tip 7 has a through hole and is connected with the pipe end of described mist conduit 6 and has the through hole that a plurality of and described heat storage 5 is connected along its circumferencial direction; An end wall of described accumulation of heat (heat exchange) chamber 1 is connected with an end wall of empty (cigarette) air chamber 8, described sky (cigarette) air chamber 8 sidewalls are equipped with three-way valve 3 on it pipeline is connected with its four-way change-over valve 2 that is provided with air intake 11 and waste gas outlet 12, another end wall of described sky (cigarette) air chamber 8 is connected with oxygen mix shower nozzle 13, described oxygen mix shower nozzle 13 is separately positioned on gas pipeline 10 that valve 4 is housed on it and the end of on it oxygen channel 14 of valve 9 being housed, described oxygen mix shower nozzle 13 and described mist conduit 6 coaxial being oppositely arranged.Described heat storage can be formed for some thermal storage units of determining by the amount of stored heat requirement, and the cell cube material is cordierite, aluminium oxide.
Operation principle:
Oxygen mix shower nozzle 13 places at the thermal storage type oxygen-enriched combusting device are fully mixed combustion gas and oxygen, and spray into the mist conduit 6 that is arranged on the regenerator center; Describedly mix once more at the burner tip place with the combustion air that is preheating to 900～1000 ℃ through well-mixed combustion gas and oxygen, and burning; The described combustion air that is preheating to 900～1000 ℃ is by the Heat Room 1 in the thermal storage type oxygen-enriched combusting device by the air at room temperature that blasts through four-way change-over valve 2, air at room temperature and the heat exchange of high-temperature heat accumulation body have absorbed the heat of heat storage 5 and have been preheated and formed; Meanwhile, another thermal storage type oxygen-enriched combusting device in the stove is 1000～1100 ℃ high-temperature flue gas through a plurality of through hole inlet temperatures along the setting of burner tip circumference, high-temperature flue gas through with the regenerator of described thermal storage type oxygen-enriched combusting device in heat storage 5 heat exchange, most of heat of high-temperature flue gas is absorbed by heat storage, flue-gas temperature drops to 150～200 ℃ by 1000～1100 ℃, forms waste gas and is discharged from described thermal storage type oxygen-enriched combusting device; (be generally 30 seconds to 2 minutes through a commutation cycle, can regulate according to factors such as exhanst gas outlet temperature or air preheating temperatures) reversal valve automatic reverse, in two thermal storage type oxygen-enriched combusting devices, carry out above-mentioned inverse process, the regenerator in last cycle becomes Heat Room, and Heat Room then becomes regenerator; Repeat aforesaid step then.
