Description

Novel nitrogen generator

Technical Field

The utility model relates to the field of nitrogen generators, in particular to a novel nitrogen generator.

Background

Nitrogen is a simple substance formed by nitrogen element, and the chemical formula is N2. The nitrogen oxide-containing gas is colorless and odorless inert gas at normal temperature and normal pressure, can react with hydrogen to generate ammonia only under the conditions of high temperature and high pressure and a catalyst, and can be combined with oxygen to generate nitrogen oxide under the condition of discharging; nitrogen has wide application in the fields of chemical industry, petroleum industry, electronic industry, food industry, metal smelting, processing industry, etc. With the rapid development of the chemical industry, the demand for nitrogen has also increased dramatically.

The nitrogen generator is used as an instrument for rapidly extracting nitrogen, and advanced gas separation technology is adopted. The high-purity nitrogen is prepared by using a high-quality imported Carbon Molecular Sieve (CMS) as an adsorbent and adopting a Pressure Swing Adsorption (PSA) principle at normal temperature to separate air. The diffusion rates of the oxygen gas molecules and the nitrogen gas molecules on the surface of the molecular sieve are different, the diffusion rate of the gas molecules (O2) with smaller diameters is faster, more gas molecules enter micropores of the carbon molecular sieve, the diffusion rate of the gas molecules (N2) with larger diameters is slower, and the gas molecules enter the micropores of the carbon molecular sieve less. This selective adsorption difference of carbon molecular sieve to nitrogen and oxygen results in oxygen enrichment in the adsorption phase and nitrogen enrichment in the gas phase in a short time, so that oxygen and nitrogen are separated, and gas phase enriched nitrogen is obtained under PSA conditions. The common nitrogen generator, after letting in high-pressure gas, through the pressure effect of air chamber, with the air filtering out, indoor compressed air can produce a large amount of moisture and condense, leads to the nitrogen gas in the gas chamber of extraction not pure, and this kind of device needs more frequent filter core of changing, and most device itself is fixed by the bolt, and it is loaded down with trivial details to dismantle. Therefore, we propose a new type of nitrogen generator.
