Description
Technical field:
The utility model is specifically related to a kind of shaft furnace assembled nozzle, belongs to the field of combustion technology of kiln, is adapted to the burn application of refractory material.
Background technology:
Known to inventor, the burner used in current domestic shaft furnace sintered bauxite process is diffusion type burning, and conventional diffusion type burning is that combustion-supporting gas and the burning of mixing limit, combustion gas limit have several shortcoming; First surplus causing combustion-supporting gas owing to mixing bad meeting, the temperature that improve smoke evacuation makes kiln thermal loss strengthen.Second badly makes combustion gas can not cause fuel excess by Thorough combustion owing to mixing, and therefore wastes fuel.The working method of the burner on existing designed combustion device sinters under thermal-radiating condition by external flame, simultaneously maximum temperature position on kiln wall not at agglomerate bodies, interior kiln wall and sinter are by radiation delivery part heat energy, it not flame direct sintering, so in concrete operations the crater of kiln wall because of sintering warpage especially severe, in addition kiln within the walls temperature be waste fuel higher than agglomerate bodies temperature.
Summary of the invention:
The purpose of this utility model is exactly to overcome above-mentioned defect, provides one that combustion-supporting gas and combustion gas can be made fully to mix, and can make combustion-supporting gas, combustion gas and combustion flame Appropriate application and the high shaft furnace assembled nozzle of efficiency of combustion.
The utility model realizes according to following technical scheme, described shaft furnace assembled nozzle is characterized in that arranging an air hose 1, the outside of air hose 1 sheathed air inlet pipe 3, gap is left between air inlet pipe 3 and air hose 1, air inlet pipe 3 front end tube wall is provided with fuel gas inlet 4, air inlet pipe 3 is provided with plug 8 near fuel gas inlet 4 one end, the outside of air inlet pipe 3 sheathed mixing tube 2, the rear end tube wall of mixing tube 2 is provided with gas port 13, the front end tube wall of mixing tube 2 is provided with mixed gas outlet 10, connecting plate 6 is installed in the outside of mixing tube 2, secondary air channel 11 is set in the outside of mixing tube 2, secondary air channel 11 rear end is provided with ring flange 7, ring flange 7 and connecting plate 6 are fixed by screw 5, the tube wall of secondary air channel 11 arranges air intlet 12, secondary air channel 11 is fixed on kiln wall 9, air hose 1 and mixing tube 2 fixedly mount, air hose 1 and air inlet pipe 3 fixedly mount, gap is left between mixing tube 2 and connecting plate 6.
Shaft furnace assembled nozzle of the present utility model is that combustion gas and primary air enter mixture pipe simultaneously, passes through to regulate flame in secondary wind direction shaft furnace, achieve shaft furnace to the sintering firing thing, comprise in mixture pipe after mixing; Air hose, air inlet pipe, mixing tube, secondary air channel, for the sinter in kiln provides required sintering temperature.
Shaft furnace assembled nozzle of the present utility model, have and significantly enhance sintering quality and sintering velocity, can correctly meet kiln temperature constant, implement in refractory material sintering process, effectively utilize the flame of fuel burner nozzle, reduce the advantage of the consumption efficient energy-saving of fuel.
