Detailed Description

The present invention will be further described with reference to the accompanying drawings. The utility model provides a heat pump water heater based on methyl alcohol heating which characterized in that: it includes compressor 1, methyl alcohol catalytic heater, flow controller 3 and water route heat exchanger 2 through refrigerant pipe connection, methyl alcohol catalytic heater include heat preservation shell 4 and locate heat transfer chamber 41 in it, be provided with heat transfer coil 5 in the heat transfer chamber 41, heat transfer coil 5's feed liquor pipe 51 is connected with flow controller 3, heat transfer coil 5's drain pipe 52 is connected with the compressor, the bottom of heat transfer chamber 41 is provided with methyl alcohol filler 6 and catalyst filler 7, methyl alcohol and catalyst chemical reaction in heat transfer chamber 41 produce the heat and heat transfer coil 5 and heat.

The heat preservation shell 4 is vertically arranged, and correspondingly, the heat exchange coil 5 is also vertically arranged in the heat preservation shell 4.

The top of the heat preservation shell 4 is provided with an exhaust port 8, and the exhaust port 8 is covered with a gas filter 9.

Two sections of circulating pipes 10 are arranged at the upper end and the lower end of the heat preservation shell 4, and circulating pumps 11 are installed on the circulating pipes 10 in series.

The methanol filling port 6 and the catalyst filling port 7 are arranged at the bottom of the heat preservation shell 4, and a blower 12 is arranged on the side wall of the heat preservation shell 4 and can inject fresh air into the heat preservation shell 4.

The methanol filling port 6 is connected with a methanol filling machine, and the catalyst filling port 7 is connected with a catalyst filling machine.

The working principle is as follows: when the heat pump works, high-pressure steam discharged by a compressor 1 enters a waterway heat exchanger (condenser) 2, refrigerant steam is condensed into liquid, the liquid enters an evaporator inlet pipe through a throttling device 3, heat is absorbed in an evaporator to drive a refrigerant to form a methanol catalytic heater, a methanol filling machine fills methanol with a set amount into a heat-insulating shell 4 through a methanol filling port 6, a catalyst with a set amount is filled into the heat-insulating shell 4 through a catalyst filling port 7, and a blower 12 works to fill fresh air into the heat-insulating shell 4; methanol, catalyst and air are mixed in the heat-insulating shell 4 to generate catalytic reaction to generate heat to heat the heat-exchanging coil 5, and the evaporated refrigerant is sucked by the compressor, so that the heating cycle is realized in a repeated way. Finally, the function of providing hot water for the user is realized.

Wherein, it is required to be noted that: after the methanol and the catalyst enter the heat-insulating shell, the circulating pump 11 works to drive the alcohol, the catalyst and the air in the heat-insulating shell 4 to circulate, so that the methanol and the catalyst are fully mixed to generate a catalytic reaction; the water and carbon dioxide produced after the catalytic reaction of methanol, catalyst and air are filtered by the gas filter 9 and discharged from the exhaust port 8. The control system monitors the working state of the methanol catalytic heater in real time, and controls the intensity of catalytic reaction by adjusting the injection amount and the injection proportion of methanol and catalyst so as to control the heating temperature to correspond to the hot water demand of a user.

Further: utilize the heat pump principle in the present case, but methanol catalytic heater places in different positions in condenser (water heat exchanger), for example indoor outer components of a whole that can function independently put, transfers the heat to the condenser in to cold water heating through compressor and relevant pipeline, when avoiding methanol catalytic heater waste gas to indoor pollution, also provides sufficient fresh air for methanol catalytic heater.

Further: methanol catalytic heater is a flameless heating device in the present case, thereby it heats the conduction oil to mainly make methyl alcohol carry out quick oxidation reaction release heat, is the exothermic reaction through methyl alcohol oxidation reaction, to the heating of heat exchange coil pipe, realizes the indirect purpose to the water route heating, in the waste gas that catalytic reaction produced, does not contain the material of harm (sulfur oxide, nitrogen oxide, carbon monoxide, small particulate matter etc.), is a security height, and the reliability is high, to environment friendly innovative device. The technical situation that the traditional air energy heat pump cannot provide enough hot water for users to use in the extreme environment is solved, and therefore the system can be widely used.
