An anti-scald, safe, low-pressure, environment-friendly hydrogen generator and gas preparation method

Abstract

The present invention relates to an inflatable device for producing hydrogen, in particular to an anti-scalding, safe, low-pressure, environment-friendly hydrogen machine and gas preparation method for inflating toy balloons and advertising balloons. The hydrogen machine of the present invention includes: a liquid inlet , reactor, purifier, check valve, gas-water mixing cooler, gas-water separator and sewage storage tank. During the preparation process, the reaction liquid is injected into the reactor through the liquid inlet, and the occurrence of the reaction is controlled through the liquid inlet valve. And stop, purify and preliminarily cool the foam-containing crude hydrogen product prepared by the reactor through the purifier, further cool the pure hydrogen through the gas-water mixing cooler, and finally use the gas-water separator to obtain hydrogen and cooling water Separation to achieve the purpose of aeration. The hydrogen produced by the invented hydrogen machine has high purity and good aeration effect. At the same time, the reaction residual liquid can be collected and reused, which greatly reduces energy consumption and material consumption, making the entire preparation process economical, reasonable, environmentally friendly and safe.

Description

technical field [0001] The invention relates to an inflatable device for producing hydrogen, in particular to an anti-scalding, safe, low-pressure, environment-friendly hydrogen machine and a gas preparation method for inflating toy balloons and advertising balloons. Background technique [0002] At present, with the increasing use of toy balloons, advertising floating balls, etc., there are many hydrogen-producing and inflatable equipment on the market. The most widely used are: high-pressure double-barrel hydrogen generator, high-pressure single-barrel hydrogen generator and zero-pressure hydrogen generator. Hydrogen generators, these hydrogen generators generally use aluminum or ferrosilicon powder to react with water and caustic soda to produce hydrogen with high temperature and water vapor. After treatment, it is used to inflate products such as toy balloons and advertising floating balls. Yet these devices also have certain defectives to varying degrees. [0003] The ...

Problems solved by technology

However, these devices also have certain defects to varying degrees.

[0003] The disadvantages of high-pressure double-barrel hydrogen generators and high-pressure single-barrel hydrogen generators are: high temperature and high pressure are generated during use, and there are potential safety hazards

For the zero-pressure hydrogen generator: First, when the zero-pressure hydrogen generator is working, the alkaline water and aluminum in the reaction tank react to produce hydrogen, and at the same time generate high temperature. Potential safety hazards, such as: a non-pressurized hydrogen machine (invention patent number: CN2014108393210, announcement number: CN104555917A) using this hydrogen machine has a good inflation effect and does not generate high pressure inside the machine, but there are safety hazards and environmental pollution that may burn the operator, The rate at which hydrogen is produced is also difficult to control

Furthermore, the reaction barrel of the zero-pressure hydrogen machine is directly connected to the cooling water barrel. After the hydrogen production reaction is completed, the generated sewage directly flows into the cooling water to cause environmental pollution.
