A methanol-water reforming hydrogen production generator for communication base stations

Abstract

The invention discloses a reforming hydrogen production generator for a communication base station. The reforming hydrogen production generator comprises an electric control module, a liquid inlet module, a hydrogen production module, a power generation module and a vacuum pumping module, wherein the electric control module comprises a control mainboard, a voltage regulator module and a DC conversion unit; the control mainboard controls the liquid inlet module, the hydrogen production module, the power generation module and the vacuum pumping module to work; the liquid inlet module comprises a storage box, a liquid inlet master pipe, a methanol pump, a starting liquid inlet electromagnetic valve, a starting liquid inlet branch pipe, a hydrogen production liquid inlet electromagnetic valve and a hydrogen production liquid inlet branch pipe; an automatic liquid level control module is arranged in the storage box; the vacuum pumping module comprises two vacuum pumping assemblies; each vacuum pumping assembly is provided with a vacuum pumping battery valve and an exhaust pipe; and the vacuum pumping module vacuumizes the liquid inlet module and the hydrogen production module before the hydrogen production generator is started or produces hydrogen. Cooperation of various parts of modules is good; an electric control system and a reformer are stable to work; the reformer is high in hydrogen production efficiency and good in stack power generation effect; and the running noise of the overall reforming hydrogen production generator is low.

Description

technical field [0001] The invention relates to the technical field of hydrogen production and power generation equipment, in particular to a methanol water reforming hydrogen production generator used for communication base stations. 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, and will not pollute the environment; while coal and oil combustion mainly produce CO 2 and SO 2 , can produce the greenhouse effect and acid rain respectively. Coal and petroleum reserves 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 the big "warehouse" of hydrogen, which contains 11% hydrogen. There is about...

Problems solved by technology

However, the existing methanol-water reforming hydrogen generators used for communication base stations and other generators still have the following defects: First, the methanol-water reforming hydrogen generator needs to be in a pure environment inside the reformer, so that the reformer The H produced after the reaction 2 and CO 2 When passing through the palladium membrane separator in the separation chamber, the damage to the palladium membrane separator can be reduced and the service life of the reformer can be prolonged. System, reformer and other systems connected to it have been in a polluted environment for a long time, the effect of reforming hydrogen production is poor, the amount of hydrogen production is small, and the service life of palladium membrane is short; second, the existing methanol water used in communication base stations The reforming hydrogen production generator lacks effective monitoring of the methanol water level, often due to the depletion of the stored methanol water, the hydrogen production is stopped, and the communication base station is powered off, which affects the transmission of signals; the third is methanol water reforming The coordination between the various parts of the hydrogen production generator is poor, and the control of the electronic control system is unstable. The methanol water reforming hydrogen production generator needs an external power supply when starting up. The reforming hydrogen production device and the starting device of the hydrogen production system are independent of each other. The advanced liquid delivery system transports the raw material liquid, which has high cost, poor connection and imprecise control
