Please refer to shown in Fig. 1-Fig. 5, the utility model typed high temperature air burning device include burner hearth 1, extend into the burner 12 of burner hearth, respectively by first connect air port 8, the second connect the first composite heat-exchanger 10 that air ports 16 connect burner hearth 1 with the second composite heat-exchanger 14, be connected in the four-way change-over valve 18 between the first composite heat-exchanger 10 and the second composite heat-exchanger 12, air blast 4 and the air-introduced machine 2 being connected with four-way change-over valve 18.Wherein, burner 12 is connected with fuel supply pipe road 13.
Between described the first composite heat-exchanger 10 and four-way change-over valve 18, be connected by the first connecting pipe 7; And be connected by the second connecting pipe 15 between described the second composite heat-exchanger 14 and four-way change-over valve 18.Described four-way change-over valve 18 connects air blast 4 by intake stack 5, and meanwhile, described four-way change-over valve 18 also connects air-introduced machine 2 by exhaust duct 3.
The first composite heat-exchanger 10 is connected with a combustion air air blast 19 by combustion air first pipeline 9, the first composite heat-exchanger 10 is connected by a combustion air second pipe 11 with the second composite heat-exchanger 14, and the second composite heat-exchanger 14 is connected by combustion air the 3rd pipeline 17 with burner 12.
The structure of first, second composite heat-exchanger is identical, as shown in Figure 4, Figure 5, the utility model embodiment is described as an example of the first composite heat-exchanger 10 example, and the first composite heat-exchanger 10 includes outer wall 101, high temperature air port 102, heat-storing sphere 103, cold air diffuser 104, a combustion air pipeline 105.Wherein, combustion air pipeline 105 two ends are connected with a combustion air second pipe 11 with combustion air first pipeline 9 respectively.
When work, a combustion air is by combustion air air blast 19 air blast, gas enters the high-temperature region of the first composite heat-exchanger 10 through combustion air first pipeline 9, flow out after the first composite heat-exchanger the high-temperature region that enters the second composite heat-exchanger 14 by combustion air second pipe 11, flow out after the second composite heat-exchanger by combustion air the 3rd pipeline 17 and enter the fuel mix burning that burner 12 and fuel channel 13 are sent into.
Simultaneously, secondary combustion-supporting wind by air blast 4 air blast, gas through intake stack 5, four-way change-over valve 18, while entering the first composite heat-exchanger 10 through the first connecting pipe 7 again, the heat of the fire-resistant heat-storing sphere in the first composite heat-exchanger 10 has been passed to air, make atmosphere temperature rising reach 1100 DEG C of above high temperature, enter burner hearth through the first connection air port 8, the fuel secondary mixed combustion that this high temperature air is supplied with burner 12 in burner hearth; Combustion product (flue gas) enters the second composite heat-exchanger 14 through the second connection air port 16, and heat is passed to the fire-resistant heat-storing sphere in the second composite heat-exchanger 14.Flue-gas temperature is reduced to below 150 degree from 1200 degree, is discharged into environmental protection flue from the second connecting pipe 15, four-way change-over valve 18, exhaust duct 3 and air-introduced machine 2.
When after reversal valve 18 commutations, normal temperature air is by air blast 4 air blast, through intake stack 5, four-way change-over valve 18, while entering the second composite heat-exchanger 14 through the second connecting pipe 15 again, fire-resistant heat-storing sphere in the second composite heat-exchanger 14 become heat release from heat absorption, heat has been passed to air, make atmosphere temperature rising reach 1100 DEG C of above high temperature, enter burner hearth 1 through the second connection air port 16, the fuel combustion that this high temperature air is supplied with burner 12 in burner hearth; Combustion product (flue gas) enters the first composite heat-exchanger 10 through the first connection air port 8, at this moment the fire-resistant heat-storing sphere in the first composite heat-exchanger 10 is no longer heat release but absorbs the heat in flue gas, the temperature of flue gas is dropped to below 150 degree, be discharged into environmental protection flue from the first connecting pipe 7, four-way change-over valve 18, exhaust duct 3 and air-introduced machine 6.
As can be seen here, for a combustion air, through the high-temperature region of the first and second composite heat-exchangers, no matter whether secondary combustion-supporting wind commutates, all will the flow through high-temperature region of 900-1200 degree, produce heat exchange with high-temperature gas in two composite heat-exchangers and high-temperature heat accumulation ball, thus easily by self temperature increase to 300-500 degree.For secondary combustion-supporting wind, along with the commutation of reversal valve, from all switching directions of the gas the first connecting pipe 5 to second connecting pipes 9 and heat flow direction.Air inlet, fume emission are changed repeatedly, and variation is also followed in flame-proof sphere heat release, accumulation of heat, and secondary combustion-supporting air temperature remains at 1000-1100 DEG C (lower 80 ~ 150 DEG C than furnace temperature).So just by the waste heat recovery of a large amount of flue gases, the combustion air and the secondary combustion-supporting wind that participate in burning are all high temperature airs, have realized high-temperature air burning truly.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
