The invention comprises a combustion-supporting fan 01, a conduit 17, a burner housing 12, a pipe sleeve 20, a combustion-supporting air pipe 21, a combustion chamber 18, a burner air inlet main pipe 10 and an electric control cabinet 06, wherein the electric control cabinet 06 is arranged on a rear end cover 11 and is used for automatic ignition, temperature control and the like, so that a combustion and control integrated whole machine is formed. Specifically:
the guide pipe 17 is fixed at the front end of the pipe sleeve 20 through the screw 13, the combustion-supporting air pipe 21 is fixed at the rear end of the pipe sleeve 20, the burner housing 12 is sleeved outside the combustion-supporting air pipe 21, and the combustion chamber 18 is arranged in the guide pipe 17.
The front end of the combustion chamber 18 is provided with a front end center opening, the rear end of the combustion chamber 18 is provided with a rear end center opening, the side wall of the combustion chamber 18 is provided with a plurality of air openings 19, the outlet end of the main air inlet pipe 10 of the combustion machine is provided with a center pipe 22 and a plurality of branch pipes 16, the center pipe 22 is connected with the rear end center opening of the combustion chamber 18, and the branch pipes 16 are uniformly distributed outside the combustion chamber 18 and are communicated with the outer edge of the front end center opening to form a support frame of the combustion chamber 18. A first air duct 23 is formed between the burner housing 12 and the combustion-supporting air duct 21, and a second air duct 26 is formed between the combustion chamber 18, the central tube 22, the branch tube 16, the inner wall of the guide tube 17 and the inner wall of the combustion-supporting air duct 21.
Further, the conduit 17 and the combustion-supporting air duct 21 are concentrically arranged, and the inner diameters of the conduit 17 and the combustion-supporting air duct 21 are equal, wherein the conduit 17 is preferably made of heat-resistant stainless steel materials so as to achieve the effects of high temperature resistance and long service life; the combustion-supporting air pipe 21 and the burner housing 12 are made of common carbon steel, the pipe sleeve 20 is made of steel casting, and the combination ensures that the structure is more reasonable and the cost is lower.
In the invention, by arranging two air channels (the first air channel 23 and the second air channel 26), the combustion air can be uniformly dispersed around the outer wall of the combustion air pipe 21 and then enter the combustion air pipe 21 to be mixed with the fuel gas, so that the effects of reducing the flow rate, stabilizing the wind pressure and prolonging the mixing time are achieved.
In operation, the combustion-supporting fan 01 is disposed at one side of the burner housing 12, in order to reduce the wind speed, after the combustion-supporting fan 01 is opened, the combustion-supporting air in the combustion-supporting fan 01 cannot directly enter the combustion-supporting air duct 21 at a high speed, but flows into the inlet of the combustion-supporting air duct 21 along the first air duct 23 (the gap between the burner housing 12 and the combustion-supporting air duct 21), then sequentially enters the conduit 17 along the second air duct 26 (the gaps between the combustion chamber 18, the central tube 22, the branch tubes 16, the conduit 17 and the combustion-supporting air duct 21), then enters the combustion chamber 18 from the air openings 19 around the combustion chamber 18, and meanwhile, the water gas respectively enters the combustion chamber 18 along the central tube 22 and the branch tubes 16 and is mixed with the combustion-supporting air in the combustion chamber 18 for combustion. The water gas entering the combustion chamber 18 along the central pipe 22 and the combustion air in the combustion chamber 18 are mixed and combusted for the first time in the central opening at the rear end of the combustion chamber 18, and the water gas is wrapped and mixed by the combustion air and is easy to ignite because the water gas and the combustion air quantity are small; the water gas entering the combustion chamber 18 along the branch pipe 16 is mixed and stirred for the second time with the combustion-supporting air in the chamber and the flame with rich air flowing forward from the central port at the rear end of the combustion chamber 18 at the central port at the front end of the combustion chamber 18, so that the combustion is more complete and complete. Therefore, the structure and the mode of the scattered and bypass combustion-supporting air and secondary mixing and combustion solve the problems of too rapid flow rate, uneven mixing, incomplete combustion and the like caused by direct air supply of the combustion-supporting fan 01, and the energy conservation is more remarkable.
As shown in fig. 4, the combustion chamber 18 has a "horn" shape, and the diameter of the front end center opening is larger than the diameter of the rear end center opening. It should be noted that, the "loudspeaker" shape structure not only can prolong the mixing time of the combustion flue gas, but also can reduce the flue gas injection speed, avoid appearing "getting off fire" situation because of too fast in the combustion process, cause the potential safety hazard. Specifically, after the combustion flame passes through the "horn" -shaped combustion chamber 18 (from the rear end center opening to the front end center opening), the flame speed is slowed down due to the increased volume of the operation channel, which is beneficial to mixing with a large amount of cold air, ensures uniform hot air fed into the drying kiln, and has enough quantity and heat to meet the high power and high hot air quantity required by drying the green body.
Further, the combustion chamber 18 is formed by mutually splicing a plurality of trapezoid plates into a horn shape, each trapezoid plate is provided with a plurality of air ports 19 with different sizes in a linear arrangement, and the aperture of each air port 19 is gradually increased from the upper bottom edge to the lower bottom edge of the trapezoid plate. Wherein the outlet of the branch pipe 16 is close to the outlet of the horn-shaped combustion chamber 18, uniformly distributed around the outer side of the combustion chamber 18 and communicated with the outer edge of the front end center opening.
In order to adapt to the water gas fuel with lower heat value, the air inlet pipeline has a circular horn-shaped structure which is formed by a plurality of heat-resistant stainless steel trapezoidal plates and gradually expands in diameter in the aspect of mixing air and gas besides increasing the inner diameter according to the power requirement. Each trapezoid plate is provided with a plurality of holes to form air inlets 19, the diameter of each air outlet 19 is increased along with the increase of the area of the horn shape (namely, the diameters of air holes of trapezoid short sides are sequentially increased when the diameters of the air holes are gradually increased to long sides), the air speeds of entering at each position and different diameters are also different, the stirring effect on the dispersed entering fuel gas can be achieved, and the mixing efficiency is improved. The flame of the first mixed combustion flows along the direction from the central opening of the rear end to the central opening of the front end along the gradually enlarged horn-shaped combustion chamber 18, so that the flow speed of the flue gas is reduced, the contact time with the combustion-supporting air entering through the peripheral air openings 19 is longer, the mixing is more uniform and the energy is saved; after the flame approaches the horn-shaped outlet, the flame is further mixed with the fuel gas and the combustion-supporting air sprayed by the branch pipe 16, the temperature is increased, and the hot air quantity is increased.
