The working principle is as follows: when the dryer needs to work, the ventilation device 21 is started to force the air in the dryer to be communicated with the heat exchange cavity in the heat exchange cylinder on the methanol heater through the pipeline, and airflow circulation is formed. Meanwhile, a methanol pump in the methanol heater absorbs methanol from a methanol liquid storage tank 10, the methanol is pressurized by the methanol pump, high-pressure methanol is sprayed into an atomizing chamber from a methanol spray nozzle 7 in an atomizing manner, a fan works at the same time, fresh air is sucked from the outside, so that the air and the atomized methanol are fully mixed in the atomizing chamber and are blown into a heating pipe under the action of air pressure, due to the guidance of air flow, when the air saturated with the atomized methanol passes through a vent hole of a catalytic cake, the methanol in the air and the catalyst on the outer surface of the catalytic cake and in the vent hole generate chemical reaction, a large amount of heat is generated after the methanol catalytic reaction, the heat heats a heat storage cake and a heating pipe through the outer surface of the catalytic cake, finally the generated heat is transferred into a heat exchange cavity through the heating pipe, and when cold air in a dryer enters the heat exchange cavity from the inlet pipe, the cold air is contacted with heat exchange fins in the heat, heated air is discharged from an outlet pipe 12 at the upper end of the heat exchange pipe, and hot air enters the inside of the dryer through a pipeline to continuously provide a heat source for the dryer.
Further: in order to increase the contact area between the methanol and the catalyst and increase the heat productivity, the number of the catalytic cakes and the heat storage cakes in the scheme can be set according to actual requirements, and the diameters and the heights of the catalytic cakes and the heat storage cakes can be correspondingly adjusted. When the air with methanol passes through the multi-layer catalytic cakes once, the methanol in the air is gradually adsorbed by the catalytic cakes, and simultaneously, water and carbon dioxide generated after the methanol reacts with the catalyst are discharged through an exhaust pipe at the top of a heating pipe.
Further: in order to increase the heat transfer area of catalysis cake, promote heat exchange efficiency, the mode installation that catalysis cake and heat accumulation cake are range upon range of in turn has been adopted in this case, when catalysis cake and methyl alcohol reaction produced the heat, heat on the catalysis cake cylinder can directly transmit the heat transfer chamber through the heating pipe, and the heat of terminal surface can transmit to in the heat accumulation cake about the catalysis cake, wherein, heat accumulation cake adopts the preparation of mullite or cordierite material that specific heat capacity is big, it can play the effect of quick absorbed heat, make the heat that the catalysis cake produced in time outwards release, promote thermal conductivity efficiency. Simultaneously, when the catalysis cake heats, the mixture of air and methyl alcohol in it that flows through also can be heated by it, consequently, when the gas of high temperature has passed through the catalysis cake and has removed in to the heat accumulator, the heat accumulator also can play the heat in the absorbed gas for the methyl alcohol gas temperature that gets into next catalysis cake reduces, is favorable to increasing the difference in temperature, promotes the heat exchange efficiency of next catalysis cake. The heat accumulator can absorb a large amount of heat and release the heat to the heating pipe through the outer cylindrical surface of the heat accumulator due to large specific heat capacity of the heat accumulator, and the heating effect on a heat exchange medium in the heat exchange cavity is achieved.
Further: wherein, because the catalytic cake has a certain service life, when the catalytic cake is used to the service life, the catalytic cake needs to be replaced. In addition, in order to make the heat conduction between the catalytic cake and the heat storage cake and the heating pipe good, the outer cylindrical surfaces of the catalytic cake and the heat storage cake are required to be in close contact with the inner wall of the heating pipe as much as possible, so that the operation is troublesome when the catalytic cake needs to be replaced, and the catalytic cake is extremely easy to damage.
