Electric generator based on methanol water hydrogen-making system and electricity generation method thereof

Abstract

The invention discloses an electric generator based on a methanol water hydrogen-making system and an electricity generation method thereof. The electric generator comprises a methanol water storage container, a delivery pump, a heat exchanger, a reformer, a separation device and a fuel cell, wherein the delivery pump is used for delivering methanol and water to a reforming chamber of the reformer; the heat exchanger is used for carrying out heat exchange on the low-temperature methanol and water and a high-temperature mixed gas output from the reforming chamber; the reformer is provided with the reforming chamber and an electric heater, and the electric heater provides heat energy for the reforming chamber; and the high-temperature mixed gas which takes carbon dioxide and hydrogen as main parts is prepared in the reforming chamber, passes through the heat exchanger and then enters the separation device to be separated to obtain the hydrogen, and the hydrogen is delivered to the fuel cell and subjected to electrochemical reaction in the fuel cell to generate electric energy, a part of the electric energy provides electricity for the delivery pump and the electric heater, and the rest of the electric energy is output. According to the electric generator, the reformer has no need of being provided with a combustion chamber, an air inlet fan, an air inlet channel and a smoke window, the heating temperature inside the reformer is easily controlled and stable, and the reformer is simple in structure, stable in operation and low in overhaul difficulty.

Description

technical field [0001] The invention relates to the technical field of power generation equipment, in particular to a generator based on a methanol-water hydrogen production system and a power generation method thereof. Background technique [0002] Hydrogen is one of the most ideal energy sources in the 21st century. When burning the same weight of coal, gasoline and hydrogen, hydrogen produces the most energy, and the product of its combustion is water without ash and waste gas. pollute the environment; while coal and oil combustion mainly produce CO 2 and SO 2 , which can produce the greenhouse effect and acid rain respectively. The reserves of coal and oil are limited, while hydrogen is mainly stored in water, and the only product after combustion is water, which can continuously produce hydrogen and never run out. The distribution of hydrogen is very wide, and water is a large "warehouse" of hydrogen, which contains 11% hydrogen. There is about 1.5% hydrogen in soil...

Problems solved by technology

[0005] Yet the above-mentioned system that utilizes the hydrogen produced immediately to generate electricity also has the following deficiencies: one, because the reformer needs to be provided with a combustor, therefore, the reformer also needs to be provided with an intake fan for blowing in oxygen in the air and The air inlet channel and the chimney for exhausting the exhaust gas generated after combustion. The high-temperature exhaust gas is discharged from the chimney, which not only wastes heat energy, but also easily affects the operation of various parts of the hydrogen production system; Soaring to over 1000°C in a short period of time, it is easy to burn out the reformer, and it is difficult to control the heat release mode of hydrogen combustion, and the temperature stability of the combustion chamber is poor (the temperature of the combustion chamber usually requires between 405-570°C); the third , The reformer is equipped with gasification chamber, combustion chamber and other chambers, air intake fan, air intake channel, and smokestacks and other components, which increases the structural complexity and maintenance difficulty of the reformer
