Example Embodiment

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like figure 1 As shown, this embodiment includes an alcohol tank 1 containing methanol or ethanol, and the alcohol pipe connected to the alcohol outlet 6 of the alcohol tank 1 penetrates the inner cavity of the gas-water separator 19 from the alcohol inlet 2 of the gas-water separator, and is connected with the alcohol outlet 6 of the alcohol tank 1. The heat exchange tube 4 in the inner cavity of the gas-water separator 19 is connected to the alcohol inlet end, and the inner end of the alcohol tube passes through the alcohol outlet 7 of the gas-water separator and is connected to the alcohol outlet end of the heat exchange tube 4, and the outer end is connected to a heater. The heat exchange tube 4 is in a spiral shape, which is beneficial to the heat exchange between the alcohol and the cracked gas in the heat exchange tube.

Abstract

The invention relates to a vehicle-mounted hydrogen production device, an alcohol outlet (6) of an alcohol box (1) is connected with a heater through an alcohol pipe, an alcohol gas outlet of the heater is connected with a reactor through an alcohol pipe, the reactor is provided with a pyrolysis gas outlet which is used to connect with a vehicle motor; one end of the heater is provided with a tailgas inlet which is used to connect with the vehicle motor, and the other end is provided with a tail gas outlet which is used to connect with a mufeler. By using the invention to produce hydrogen onvehicle, partial gasoline can be replaced, the atomizing, mixing and burning of gasoline can be improved and the thermal efficiency of the gasoline engine is improved. Practical detections show that when the hydrogen fraction in the fuel blends is 4.7wt%, 30-40% of fuel oil can be replaced and the total amount of hydrocarbons, nitrogen oxides and carbon monoxide in tail gas can be reduced by morethan 90%.

Description

(1) Technical field [0001] The invention relates to a special device for producing hydrogen. Specifically, it is a vehicle-mounted hydrogen production device that utilizes the exhaust heat of an internal combustion engine to reform methanol by catalytic cracking. (two), background technology [0002] Hydrogen energy is regarded as the energy source with the greatest development potential in this century because of its cleanliness, high efficiency, and renewable energy, and the existing internal combustion engines burning petroleum fuels can be mixed with hydrogen without any modification. Hydrogen fuel also has many advantages when used in automobiles. For example, the calorific value per unit mass of hydrogen is higher than that of gasoline; the flame propagation speed of hydrogen is much faster than that of gasoline; hydrogen has a wider ignition limit and lower ignition energy than gasoline. Alcohol-hydrogen combustion is a hot spot in the high-tech industry in the 21st ...
