Fast hydrogen making device capable of automatically starting in power-down condition

Abstract

The invention discloses a fast hydrogen making device capable of automatically starting in a power-down condition. An aluminum powder container is communicated with a reactor through a first electromagnetic valve and a first flow control valve sequentially to ensure that aluminum powder in the aluminum powder container enters in the reactor; the grain diameter of the aluminum powder granules is 5 nm-20 mm; the reactor is a sealed container with sodium hydroxide solid filled in the lower end; a water pipe is sequentially connected with a second electromagnetic valve, a second flow control valve and a nozzle, wherein the nozzle is arranged at the upper end of the reactor to enable water to be sprayed into the reactor; the upper end of the reactor is provided with an aluminum powder filtering screen which is connected with a third electromagnetic valve through a pipeline; the third electromagnetic valve is connected with a third flow control valve; and the third flow control valve is connected with the cathode of a fuel battery generating system. The invention has the advantages of easily obtained and cheap raw materials, easily controlled reaction speed, simple structure, environmental-friendly and pollution-free product, safe and portable use and transportation, and the like.

Description

technical field [0001] The invention relates to hydrogen production, in particular to a device for automatically starting rapid hydrogen production when the power is cut off, in particular to a device for producing hydrogen by reacting metal aluminum powder with water in the presence of sodium hydroxide. Background technique [0002] As an important chemical substance, hydrogen is widely used in chemical industry, petrochemical industry, food and metallurgical industry. Hydrogen energy is a promising energy carrier. The rapid development of the hydrogen economy has stimulated the research of hydrogen storage materials, but the cost of hydrogen storage is very high, and there are various safety problems, so the development of small, cheap, controllable, instant production, safe and reliable , There is a very urgent need for hydrogen production technology that can match with fuel cells. [0003] At present, the sources of hydrogen can be roughly divided into the following cat...

AI Technical Summary

Problems solved by technology

The device does not have the function of automatically starting when the power is cut off, and it cannot start automatically when the monitored power supply is cut off; the sodium hydroxide solution needs to be used and prepared immediately, and it may be destroyed by CO in the air. 2 polluted

[0006] In 2003, the U.S. Patent (US Pat No. 6,638,493B2) disclosed a method for producing hydrogen, disclosing the catalysis of sodium hydroxide under certain conditions, but this method cannot realize the function of automatic opening, and the operation is cumbersome. And the purity of hydrogen is not high
