Further, described kiln body width is 2.5 ~ 3 meters.
Further, described fuel burner nozzle air port is provided with the rotating disk rotated for axle center with combustion gas spout, and described rotating disk is provided with at least one ejiction opening, and this ejiction opening runs through rotating disk, and forms angle with air emission direction.
Preferably, described angle is 60 degree.
Preferably, described rotating disk is provided with 5 ~ 10 ejiction openings.
Further, described every 2 fuel burner nozzles form a fuel burner nozzle device, and described fuel burner nozzle device divides two rows to stagger up and down setting.
Preferably, fuel burner nozzle and kiln body sidewall are level 60 degree of angles.
Compared with prior art, the utility model has following beneficial effect:
1. multiple tracks thermal balance air curtain is set, high-temperature region and other warm areas are separated, run off under effectively stoping heat energy to pass through the suction function of smoke evacuation and waste heat fan, reduce gas consumption, improve energy utilization rate, and kiln car can be walked from thermal balance air curtain;
2. kiln body adopts expanded letter to arrange, and under identical thermal energy consumption area, widens product loading space, saves combustion gas, significantly improves the economic benefit of enterprise;
3. pair gas nozzle structure is transformed, and drives fuel burner nozzle turntable rotation when combustion gas is sprayed, and produces centrifugal force, makes flame spray to surrounding, and spray regime is wider, to adapt to the temperature requirements of wide-body kiln; Reasonable Arrangement fuel burner nozzle position, adjustment fuel burner nozzle angle, makes temperature stable and uniform more in high-temperature region, is conducive to goods and burns till.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is further described.
As shown in Figure 1, the utility model energy-saving tunnel kiln, is made up of kiln body, combustion system, blower fan system etc.Long 100 meters of kiln body, has preheating zone 11, clinkering zone 12 and salband 13; Preheating zone 11, clinkering zone 12 and salband 13 are equipped with kiln internal channel.Clinkering zone 12 is provided with 20 air curtains 2 in rear and front end, 1200 ~ 1400 DEG C of high-temperature regions, 10 groups are divided into by often organizing 2, be respectively equipped with 5 groups near one end, preheating zone 11 with near salband 13 one end, 2 air curtains 2 often in group air curtain 2 are corresponding is arranged on kiln body left and right sides wall 14.Kiln body top is provided with the corresponding pipeline 3 gas of high-temperature region being evacuated to air curtain 2, direction in Fig. 1 indicated by arrow is extract the gas flow of coming, extract from high-temperature region and next gas is squeezed into by corresponding air curtain 2, form 5 road thermal balance air curtains 4 in rear and front end, high-temperature region.High-temperature region and other warm areas separate by 5 road thermal balance air curtains 4, heat energy effectively can be stoped to pass through to discharge fume and the loss under the suction function of waste heat fan, reduce gas consumption, improve energy utilization rate; And kiln car can be walked from thermal balance air curtain 4.
Kiln body width is 2.8 meters, and compared with the tunnel cave of 1 ~ 2 meter, this tunnel cave can load more products and fire simultaneously, saves combustion gas, significantly improves the economic benefit of enterprise.
As Figure 2-3, combustion gas spout 51 and air port 52 is provided with in fuel burner nozzle 5 fuel burner nozzle 5, combustion gas spout 51 is with being located in air port 52 center, air port 52 is provided with the rotating disk 53 rotated for axle center with combustion gas spout 51, described rotating disk 53 is provided with 6 ejiction openings 54, and this ejiction opening 54 runs through rotating disk 53, and forms 60 degree of angle α with air emission direction, direction in Fig. 2 indicated by filled arrows is air emission direction, and the direction indicated by hollow arrow is gas injection outgoing direction.When air is beaten on rotating disk 53 ejiction opening 54, due to the effect of angle α, rotating disk 53 can rotate formation centrifugal action, make flame spray to surrounding, be diffused into high-temperature region more dispersedly, to adapt to the temperature requirements of wide-body kiln, because range of scatter is wider, the temperature in high-temperature region can be balanced, make temperature stable and uniform more, be conducive to goods and burn till.
As illustrated in figures 4-5, fuel burner nozzle 5 totally 144, being divided into 72 groups of fuel burner nozzle devices 6 by often organizing 2, being located at kiln body left and right sides wall 14,36 groups, every side fuel burner nozzle device 6, and point two rows are interspersed up and down.Often organize fuel burner nozzle device 6 and be divided into 2 fuel burner nozzles 5 in left and right, ejiction opening 54 direction and the kiln body sidewall 14 that often prop up fuel burner nozzle 5 are level 60 degree of angle β, the expansion of angle makes the combustion flame of fuel burner nozzle 5 be diffused into high temperature more dispersedly, make temperature stable and uniform more in high-temperature region, be conducive to goods and burn till.
Above-described embodiment of the present utility model is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
