It should be noted that the central processor module with the model number AT91RM9200 is only one implementation manner of the embodiment of the present invention, and is not limited to the model number of the gas flow sensor 10, and in other embodiments, the central processor module capable of implementing the above functions can be applied here.
In summary, the embodiments of the present invention provide a cyclone burner, which has at least the following technical effects:
the principle of the invention is as follows: a gas inlet 9 of the swirler assembly is connected with the gas pipe and the valve body, under the action of gas pressure in the gas pipe, gas in the gas pipe is injected into the injection pipe 2, high-speed flowing gas enters the injection pipe 2 through the gas inlet 9 of the swirler assembly, the swirler assembly can entrain air around the injection pipe 2 and enter the injection pipe 2 through an air inlet 5 of the swirler assembly, and the air and the gas in the injection pipe 2 are subjected to primary disturbance mixing through rotational flow motion; meanwhile, when the air enters the ejecting pipe 2 through the air inlet 5 of the swirler assembly, the disturbing impeller 3 rotates when the air passes through the disturbing impeller 3, the air and the fuel gas in the ejecting pipe 2 are mixed again when the impeller rotates, and the air and the fuel gas which are mixed again enter the fuel gas mixing cabin 1 and then are discharged from the exhaust hole of the fuel gas mixing cabin 1 and then are combusted. In the invention, through the design of the disturbance impeller 3, the air and the fuel gas in the injection pipe 2 can be mixed in a swirling manner again, and the mixing is more sufficient and uniform compared with the traditional single mixing (namely the one-time disturbance mixing). The design of the invention solves the problem that the existing burner has uneven mixing of air and fuel gas.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
