Hydrogen detection and purification device

Abstract

A device for detecting the content of hydrogen in mixed gas comprises a gas storage tank and a container, the container is divided into a left sub-container and a right sub-container, the left sub-container and the right sub-container are separated through a partition plate in the middle, the partition plate separates the upper face, the front face and the rear face of the left sub-container fromeach other, and a certain space is reserved on the lower side of the left sub-container. The left side sub-container is provided with a cover used for sealing the top end of the left side sub-container, the lower side face of the cover is coated with a palladium film, an air inlet is formed in the upper end of the left side wall of the left side sub-container, the air storage tank is connected with the air inlet through a hose and supplies air to the left side sub-container, and a flow meter and an electromagnetic valve are arranged on the hose. Water is contained in the container and submerges the bottom end of the partition plate in a natural state; and the top end of the right sub-container is an open space.

Description

technical field [0001] The invention relates to the field of gas detection and preparation, in particular to the fields of hydrogen content detection and hydrogen preparation. Background technique [0002] Hydrogen is a colorless, odorless, flammable and explosive gas. It is easy to leak during production, storage and transportation, or the produced hydrogen is impure, so accurate measurement of hydrogen content is required. [0003] Hydrogen measurement methods in the prior art include gas chromatographic detection technology, which has large errors, low sensitivity and complicated operation. Alternatively, an electrochemical hydrogen sensor is used, which has a wide working range and low power consumption, but the electrode life is limited, and the sensor needs to be powered, which is not safe. There is also an optical fiber sensing method. CN1587992A provides a light intensity modulated optical fiber sensor driven by a micro-cantilever beam, which is less affected by te...
