[0034] The combustion device is provided with multiple atomizing rings 3, quick heaters 5, catalytic rings 6 with heat storage function, catalytic cracking reforming chamber 7, hydrogen spray rings 8, and supplementary combustion air regulating valve 9 on the inner wall between the air inlet 1 and the variable frequency axial flow fan 2 to the nozzle 10 in sequence; the multiple atomizing rings 3 are used to atomize the mixed liquid, and an igniter 11 is also provided inside the atomizing rings 3; the quick heaters 5 are used to heat the mixed liquid droplets; the catalytic rings 6 with heat storage function are used to catalytically crack the mixed liquid droplets, and can also play a role in heat storage and temperature regulation; the catalytic cracking reforming chamber 7 is used to gasify and reform the mixed liquid droplets; the hydrogen spray ring 8 is connected to the hydrogen production device, and is used to feed hydrogen into the combustion device; the supplementary combustion air regulating valve 9 is connected to the supplementary combustion air channel 4, and is used to feed air into the combustion device when burning the alcohol-hydrogen mixture.

[0035] The quick heater 5 includes a heating layer, a vacuum layer 28 and an inner cavity 29. The heating layer is an electromagnetic generating coil 26 or a microwave generator 30, which can quickly heat the mixed liquid droplets. The igniter 11 ignites the mixed liquid droplets after they are heated.

[0038] A temperature monitoring device is also provided in the combustion device for monitoring the temperature of the combustion device; flow monitoring devices are also provided in the flow control valve 16 on the delivery pipe of the supplementary air regulating valve, the hydrogen spray ring 8, the methanol storage tank 15 and the additive storage tank 20 respectively. The above data monitoring results are used to upload to the intelligent control device 24, analyze the data and issue instructions.

[0039] The working process of the utility model is as follows:

[0040] When the device starts working, the furnace of the combustion device is first purged and emptied, the mixing device is started first, and the intelligent control device 24 controls the flow control valve 16 on the delivery pipe of the methanol storage tank 15 and the additive storage tank 20 to open, and the methanol and the additive enter the mixed liquid storage tank 18 and are mixed under the stirring of the mixer 17. The water contained in the additive will decompose into hydrogen under the action of electrolysis and high temperature.

[0041] After mixing, the intelligent control device 24 controls to open the mixed liquid control valve, and the mixed liquid enters the multi-circle atomizing ring 3 through the mixed liquid delivery pipe 13, and the axial flow fan 2 is started at the same time. The multi-circle atomizing ring 3 sprays mixed liquid droplets into the combustion device cavity through its many small holes. After entering the combustion device cavity, the mixed liquid droplets are heated to the optimal ignition temperature by the quick heater 5. When the temperature monitoring device in the combustion device detects that the temperature is suitable, the igniter 11 is started. The multi-circle atomizing ring 3 and the quick heater 5 cooperate with each other to ensure a certain high temperature condition in the combustion chamber, so that the ignition is stable and reliable. When the ignited mixed liquid droplets are pushed forward to the vicinity of the catalytic circle 6 with a heat storage function under the action of the axial flow fan 2, the ignited mixed liquid droplets are rapidly catalytically cracked under the catalytic action of the catalytic circle 6, and gasified and reformed in the catalytic cracking reforming chamber 7, which prepares the necessary prerequisites for the next step of full combustion. When the flame of the mixed liquid droplets after ignition moves to the vicinity of the hydrogen spray ring 8, the intelligent control device 24 will determine the required amount of hydrogen based on the temperature monitoring results in the combustion device, control the hydrogen generator 23 to open, and transport the generated hydrogen into the combustion device. Due to the effect of hydrogen, the flame immediately becomes fierce and the temperature rises immediately. When it finally reaches the vicinity of the nozzle 10, since the previous stage of work is carried out under an oxygen-deficient state, at this time, air enters the combustion device through the supplementary combustion air channel 4 and the supplementary combustion air regulating valve 9, and the flame becomes fierce again and sprays out of the combustion device to provide heat energy to boilers, kilns, etc. At the same time, the mixed fuel is also fully burned, and the entire combustion process is completed.

[0042] To keep the whole combustion process in the best state, an intelligent control system is indispensable. The variable frequency axial flow fan 2, igniter 11, start and stop of control equipment, temperature adjustment, and flow of mixed liquid and hydrogen in the whole device are all accurately and accurately judged by the calculation results of the intelligent control device 24, greatly reducing the mistakes of manual operation.
