Methanol water reforming hydrogen production machine and hydrogen production method thereof

Abstract

The invention discloses a methanol water reforming hydrogen production machine and a hydrogen production method thereof. The methanol water reforming hydrogen production machine comprises a methanol water storage container, a delivery pump, a frequency converter, a heat exchanger and a reformer, wherein the frequency converter is used for converting a low-frequency voltage or a direct current voltage into a high-frequency voltage required for an electromagnetic coil of an electromagnetic heater, the frequency converter is provided with a liquid cooling radiator, and a methanol water raw material flows through the liquid cooling radiator in the pumping process of the delivery pump, so that heat generated by the frequency converter is taken away by the methanol water raw material. The reformer is provided with a reforming chamber, the electromagnetic heater and a hydrogen purification device. The electromagnetic heater comprises the electromagnetic coil and a metal magnetized body. A high frequency magnetic field can be generated after the high-frequency voltage is input into the electromagnetic coil, so that the metal magnetized body emits heat due to magnetic field induction and provides thermal energy for the reforming chamber. The frequency converter is low in noise, good in cooling effect and low in energy consumption. According to the methanol water reforming hydrogen production machine, heat generated by the frequency converter can be utilized effectively.

Description

technical field [0001] The invention relates to the technical field of hydrogen preparation equipment, in particular to a methanol-water reforming hydrogen production machine and a hydrogen production 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; o...

Problems solved by technology

[0006] The frequency converter includes rectification circuit, control circuit, system detection circuit, display circuit, power control circuit, power tube or module, cooling fan, buzzer, radiator, etc. The radiator is used to dissipate heat for each functional module of the frequency converter. The radiator used in the methanol water reforming hydrogen production machine mentioned above is an air-cooled radiator, which has the following defects: First, the cooling fan of the air-cooled radiator has high noise, which is not conducive to the frequency converter and the entire methanol water reforming hydrogen production machine Second, due to the slow cooling speed of the air, the heat dissipation efficiency of the air-cooled radiator is low. When the frequency converter has power adjustment and other emergencies, there may be a peak temperature and damage the chip of the frequency converter. circuit; third, the cooling fan of the air-cooled radiator itself needs power supply to maintain operation, and consumes high energy; fourth, the heat generated by the inverter is blown away by the cooling fan, wasting heat energy in vain; fifth, when the inverter When integrated in the body of the methanol water reforming hydrogen generator, the heat discharged by the frequency converter is likely to adversely affect the electronic circuits such as the controller of the methanol water reforming hydrogen generator
