Hydrogen purification device and method for detecting hydrogen purification efficiency of hydrogen purification device

Abstract

The invention discloses a hydrogen purification device. The hydrogen purification device comprises a hydrogen storage device filled with hydrogen storage alloy powder, wherein one end of the hydrogenstorage device is connected with an inlet pipeline; the other end of the hydrogen storage device is connected with an outlet pipeline; and the hydrogen storage device is provided with a heat exchangedevice. When a hydrogen raw material mixed with impurity gas enters the hydrogen storage device through the inlet pipeline, hydrogen is absorbed by the hydrogen storage alloy powder in the hydrogen storage device; when the hydrogen raw material is stopped from entering the hydrogen storage device, gas in the hydrogen storage device is slowly discharged through the outlet pipeline, the content of impurity gas in the discharged gas is high, and then the hydrogen with gradually higher purity is slowly discharged. The complexity of the hydrogen purification device is simplified, the occupied spaceof the hydrogen purification device is reduced, the operation condition is mild, the safety is high, and the application range is wide. The invention also discloses a method for detecting hydrogen purification efficiency of the hydrogen purification device, the purification efficiency of pure hydrogen is obtained by calculating the content of impurities, and the detection precision of the hydrogen purification efficiency is improved.

Description

technical field [0001] The invention relates to the field of hydrogen purification, in particular to a hydrogen purification device and a method for detecting hydrogen purification efficiency thereof. Background technique [0002] Hydrogen, together with solar energy and nuclear energy, is known as the three major new energy sources due to its high combustion efficiency and non-polluting products. As a new energy source, hydrogen has been widely used in aviation, power and other fields; at the same time, as a reducing gas and carrier gas, hydrogen has extremely important application value in the fields of chemical industry, electronics, medical treatment, and metal smelting. Hydrogen is a colorless gas with a lower density than air. Hydrogen is a very important industrial raw material and a clean energy source. With the rapid development of science and technology, all walks of life have proposed higher and higher purity of hydrogen. requirements. [0003] The current indus...

Problems solved by technology

Pressure swing adsorption technology requires a complex and targeted impurity removal process in order to achieve hydrogen output with a purity of 5N. If the output of hydrogen with a purity of 6N is to be achieved, additional supporting devices are required. The complete set of devices is bulky and heavy. suitable for large-scale use

[0005] In the prior art, a hydrogen sensor is commonly used to detect the concentration of hydrogen, but the hydrogen sensor is only suitable for detecting the concentration of hydrogen, and is not suitable for detecting the purity of pure hydrogen, and its detection accuracy needs to be improved. For the detection of some high-purity hydrogen, hydrogen Sensors clearly struggle to meet the requirements
