Anti-scald safe, low-pressure and environment-friendly hydrogen machine and gas preparation method

Abstract

The invention relates to inflation equipment for hydrogen preparation and particularly relates to an anti-scald safe, low-pressure and environment-friendly hydrogen machine for inflating toy balloons and advertising balloons and a gas preparation method. The hydrogen machine provided by the invention comprises a liquid inlet device, a reactor, a purifier, a check valve, a gas-water mixing cooler, a gas-water separator and a sewage discharge liquid storage tank. In the preparation process, reaction liquid is injected into the reactor through the liquid inlet device, and the start/stop of the reaction is controlled through a liquid inlet valve; a foam-containing crude product of hydrogen prepared by the reactor is purified and preliminarily cooled through the purifier; the pure hydrogen is further cooled by the gas-water mixing cooler; and finally, the hydrogen and cooled water are separated by the gas-water separator to achieve an aim of inflation. The hydrogen prepared by the hydrogen machine provided by the invention has high purity, and the inflation effect is good; and meanwhile, the reaction raffinate can be reasonably recycled, the energy consumption and material consumption are greatly reduced, and the whole preparation process is 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 (inv
