Abstract
The invention discloses an air-gas premixed valve of a nozzle of a heating furnace, comprising a circular ring (1) and blades (2), wherein the blades (2) which are mutually spaced and obliquely arranged in a same direction are positioned in the circular ring (1); one ends of the blades (2) are all connected with the center of the circular ring (1), and the other ends are fixedly connected with the circular ring (1); and air passages (3) are formed among the blades (2). Because the air-gas premixed valve capable of mixing a gas with air and generating rotational flows is arranged in front of a gas spout of the nozzle, the gas and the air are sufficiently mixed and then enter a kiln for combustion, the gas is sufficiently combusted, and the spouting velocity of the mixed gas entering the kiln is increased, therefore the combustion efficiency of the kiln can be enhanced by 5-20 percent, the temperature of the kiln can be increased, the gas and the energy are saved and the production cost of the kiln is lowered.
Description
Technical field
The present invention relates to heating furnace, especially relate to the heating furnace nozzles.
Background technology
Existing kiln adopts combustion gas to heat usually, to improve the thermal efficiency and to reach environmental requirement, the most generally is the mode that adopts combustion air to enter kiln at the nozzles place with combustion gas and have the kiln heating now.The problem that this mode of heating exists is: just do not entered kiln because combustion gas fully mixes with combustion air, and combustion gas is very short in the kiln holdup time, thereby the fuel gas buring that enters kiln is incomplete, it is insufficient to burn, efficiency of combustion is not high, not only improve the production cost of kiln, and reduced the product quality that kiln is produced.
Summary of the invention
Problem at kiln heating in the above-mentioned prior art exists the present invention proposes a kind of combustion gas and air of making and fully mixes, and combustion gas is fully burned, and not only can improve the kiln efficiency of combustion and can save the empty combustion of the heating furnace nozzles premix valve of combustion gas.
The empty combustion of described heating furnace nozzles premix valve is fitted in the combustion gas spout front of nozzles, the empty combustion of described heating furnace nozzles premix valve by annulus and be positioned at annulus each other at interval and the blade that is obliquely installed in the same way form, described blade one end all links to each other with circle ring center, the other end links to each other with annulus, is formed with airway between the described blade.
The present invention is fired the premix valve owing to be provided with the sky that can make combustion gas and air mixing and produce eddy flow in the combustion gas spout front of nozzles, after fully being mixed, combustion gas and air enter the kiln burning again, the one, combustion gas is fully burned, be to improve the jet velocity that air mixture enters kiln again, thereby improved the kiln efficiency of combustion, efficiency of combustion has improved 5-20%, not only can improve kiln temperature, and saved combustion gas, and saved the energy, reduced the production cost of kiln.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present invention,
Fig. 2 is that the present invention is installed in the schematic diagram in the heating furnace nozzles,
Fig. 3 is the A-A cutaway view of Fig. 1.
The specific embodiment
At Fig. 1, among Fig. 2 and Fig. 3, the empty combustion of described heating furnace nozzles premix valve 6 is fitted in combustion gas spout 5 fronts of nozzles 4, the empty combustion of described heating furnace nozzles premix valve 6 is formed by annulus 1 and the some blades 2 that are positioned at annulus, blade one end all is positioned at circle ring center, the blade other end and annulus (circle ring inner wall) are fixedly linked, leaf cross-section is sheet, and to be prolate square, also can be arcuation shape, blade each other at interval and be obliquely installed in the same way in annulus, all be formed with airway 3 between the blade, described airway is the rectangular degree of lip-rounding, and the empty combustion of heating furnace nozzles premix valve-use metal (as heat resisting steel etc.) is welded or with ceramic, the whole manufacturing of foamed ceramics or mixed plastic forms.Be provided with foamed ceramics sheet 7 in the empty combustion of heating furnace nozzles premix valve 6 fronts.
Claims (1)
1. heating furnace nozzles sky fires the premix valve, it is characterized in that: it by annulus (1) and be positioned at annulus each other at interval and the blade (2) that is obliquely installed in the same way form, described blade one end all links to each other with circle ring center, the other end and annulus are fixedly linked, and is formed with airway (3) between the described blade.
