Problems solved by technology

[0002] As the materials of proteins, nucleic acids and other nitrogen compounds that make up organisms; the nitrogen compounds or nitrogen inhaled from the outside world are called the nitrogen source of the organism; nitrogen can be used as a nitrogen source only for nitrogen-fixing bacteria and certain radioactive substances. Nematodes and algae, etc.; the traditional high-purity nitrogen source preparation method is complicated to operate and high in cost. The rectification operation cannot guarantee the purity of the high-purity nitrogen source, which is not conducive to the preparation of high-purity nitrogen source. The rectification operation is extremely wasteful of resources. Many, time-consuming and labor-intensive; in view of these defects, it is necessary to design a high-purity nitrogen source preparation method

Abstract

The invention discloses a preparation method of a high-purity nitrogen source. The preparation method comprises the following steps of: 1, preparation of raw materials; 2, liquid deoxidation; 3, impurity treatment; 4, nitrogen source dust removal; and 5, storage and placement. In the step 1, high-purity nitrogen raw material gas is manually selected according to foreign ultrahigh-purity nitrogen indexes, and the high-purity nitrogen raw material gas is stored in a low-temperature gas tank; and the high-purity nitrogen raw material gas is detected, impurities are filtered, and the high-purity nitrogen raw material gas is oscillated and then stands for storage. The preparation method of the high-purity nitrogen source is simple to operate and low in cost, the high-purity nitrogen source is prepared from high-purity nitrogen raw material gas as a raw material through deoxidation, dehydrogenation, dehydration and dust removal, traditional rectification operation is abandoned, the purity of the high-purity nitrogen source is guaranteed, preparation of the high-purity nitrogen source is facilitated, resources are saved, operators are reduced, time and labor are saved, the process is simple and rigorous, the effect is remarkable, materials are cheap, the cost is low, cost is greatly saved, and machining and production are facilitated.
