The above-mentioned mixed solution is pumped into a first-stage heat exchanger 4, then enters the secondary heat exchanger 5 through the raw material input pipeline 2, then enters the reformer 6 through the raw material input pipeline 2, and finally enters the methanol reactor 7 through the raw material input pipeline 2, and the oil pump 12 can conduct heat The heat-conducting oil in the oil furnace 13 is transported to the methanol reactor 7 and the reformer 6 through the heat-conducting oil delivery pipeline 11, and after heating the methanol reactor 7 and the reformer 6 respectively, the heat-conducting oil flows back through the heat-conducting oil delivery pipeline 11 to In the heat conduction oil furnace 13, a heat conduction oil circulation is formed. The mixed liquid in the methanol reactor 7 reacts at a temperature of 200-260°C to produce mixed combustible gases such as hydrogen (with a content of more than 75%), oxygen, carbon monoxide, and methane, and the temperature of the mixed combustible gas is about 240°C. The mixed combustible gas enters the secondary heat exchanger 5 from the bottom of the secondary heat exchanger 5 through the combustible gas delivery pipeline 8, and then is discharged from the top of the secondary heat exchanger 5 through the combustible gas delivery pipeline 8 from the bottom of the primary heat exchanger 4 Enter the primary heat exchanger 4, and then discharge from the top of the primary heat exchanger 4, transport it to the gas supply station 9 through the combustible gas pipeline 8, and finally transport it to the user end 10 by the gas supply station 9 for use. In the primary heat exchanger 4, the combustible gas is mixed with the raw material mixture at high temperature for heat exchange, and the raw material mixture can be heated from 20°C to 60°C, and in the secondary heat exchanger 5, the combustible gas is mixed with the raw material mixture at high temperature Heat exchange can heat the raw material mixture from 60°C to 180°C. The raw material mixture at 180°C is heated to nearly 240°C by heat transfer oil in the reformer 6, and then enters the methanol reactor 7. The 240°C high-temperature mixed combustible gas after two heat exchanges is discharged from the primary heat exchanger 4 and then the temperature drops to 30°C and enters the gas supply station 9 . Through the above-mentioned heat exchange cycle process, the present invention itself consumes extremely low energy for operation, uses the generated high-temperature mixed combustible gas to carry out two-stage preheating and heating of the raw material mixed liquid, and at the same time cools down the high-temperature mixed combustible gas, realizing heat transfer. Recycling saves a lot of energy. The mixed combustible gases such as hydrogen (content above 75%), oxygen, carbon monoxide and methane produced at last can replace the existing natural gas for household use, save a lot of energy, greatly reduce the cost of use, and are suitable for widespread use.
