Catalyst 6 be cylindric, be provided with the honeycomb holes 61 that run through on its front and back terminal surface, the catalyst is detachable installs in heat exchange tube 3.

The catalyst 6 is in a coating shape and is coated and fixed on the inner wall of the heat exchange tube 3.

The heat exchange tube 3 is a copper tube or an aluminum tube.

The air outlet pipe 5 is connected with the air inlet end of the air blower 12, and the air outlet pipe 5 is connected with a pressure release valve 15 and a fresh air compensation valve 16.

The working principle is as follows: when heating is needed, the fan is started, the methanol pump sucks methanol from the methanol liquid storage tank 10, the methanol is pressurized by the methanol pump, high-pressure methanol is sprayed into the air inlet pipe from the methanol spray nozzle 8 in an atomized state and is uniformly mixed with air in the air inlet pipe, the mixture of the air and the methanol enters the heat exchange pipe and is uniformly contacted with the catalyst, the methanol, the catalyst and the air generate chemical reaction, and a large amount of heat is generated after the methanol catalytic reaction to heat the heat exchange pipe. Meanwhile, a water pump pumps cold water into the heat exchange cavity to be in contact with the outer wall of the heat exchange tube, and the heat generated after the methanol catalysis is utilized to heat the cold water outside the heat exchange tube, so that the cold water is heated to generate hot water for the water heater.

Further, in order to enable heat generated by the catalyst to be more uniformly and timely conducted into the heat exchange tube for heating, the heat exchange tube in the scheme is made of a copper tube or an aluminum tube with a good heat conduction effect, a gap is reserved between every two adjacent heat exchange tubes, so that cold water can be in full contact with the outer wall of the heat exchange tube, and the heat exchange efficiency is improved.

The catalyst can be made into granular or cylindrical shape, so that the catalyst is convenient to replace and the service life of the equipment is prolonged.
