Description

Gaseous detection device convenient to carry

Technical Field

The utility model belongs to the technical field of gaseous check out test set, specifically be a portable's gaseous detection device.

Background

PSA, a new gas separation technology, has been rapidly developed abroad since the late 60 s and early 70 s, and is based on the principle of separating gas mixtures by using differences in the "adsorption" properties of molecular sieves on different gas molecules, and it uses air as a raw material to separate nitrogen and oxygen from the air by using the selective adsorption properties of a high-performance and high-selectivity solid adsorbent on nitrogen and oxygen.

When nitrogen is prepared by using PSA technology, nitrogen obtained by pressure swing adsorption needs to be purified by using nitrogen purification equipment to improve the purity of the nitrogen, hydrogen is used for reacting with residual oxygen in the nitrogen under the action of a catalyst, water generated by the reaction is separated, and finally deep drying is carried out to obtain high-purity nitrogen.

Use sample container to detect again after the nitrogen gas sample that nitrogen gas purification equipment came out at present usually, but because sample container is mostly used repeatedly, inside remaining gas can't guarantee to replace completely, can pollute the sample, and the nitrogen gas purity that nitrogen gas purification equipment came out can reach more than 99.999%, even a little residual air also can produce serious pollution to the sample, lead to the measuring result to produce great error, therefore, the mode that uses gas detection instrument to carry out the witnessed inspections is more suitable, need a gas detection instrument that is convenient for carry in order to satisfy the requirement of witnessed inspections.
