Nitrogen making machine

Definition of nitrogen making machine
Nitrogen making machine is a device that uses air as raw material and uses physical method to separate nitrogen from oxygen and nitrogen. According to the different separation methods, namely deep cryogenic air separation method, molecular sieve air separation (PSA) and membrane air separation method, the nitrogen making machines used in industry can be divided into three types.

Two. The working principle of nitrogen making machine
1. PSA principle of nitrogen adsorption by pressure swing adsorption.
PSA pressure swing adsorption nitrogen making machine uses high quality molecular sieve as adsorbent and uses pressure swing adsorption principle to directly obtain nitrogen from compressed air. The adsorption capacity of carbon molecular sieves is different from that of pressure. If the pressure is reduced, the oxygen molecules adsorbed by the carbon molecular sieve can be desorbed, so that the carbon molecular sieve can be regenerated, and it can be repeatedly circulated alternately and continuously produce high-quality nitrogen.

2. Nitrogen principle in cryogenic air separation system
Deep cooling air separation of nitrogen is based on air as raw material, after compression, purification, and then use heat exchange to make the air liquefied into liquid air. Liquid air is mainly a mixture of liquid oxygen and liquid nitrogen. The boiling point of liquid oxygen and liquid nitrogen is different (at 1 atmospheric pressure, the boiling point of the former is -183 C, and the latter is -196 C).

3. Nitrogen principle of membrane air separation system
Nitrogen in membrane air separation is the separation of oxygen and nitrogen from air by using different gases such as oxygen and nitrogen in a membrane under different pressure.

Three. Classification of nitrogen making machines
Nitrogen making machines can be divided into industrial nitrogen making machines, food nitrogen making machines, vehicle mounted nitrogen making machines, laser cutting nitrogen making machines, vacuum heat treatment nitrogen making machines, and lead-free reflow nitrogen making machines.

Four. Application field of nitrogen making machine
Nitrogen making technology is a new technology to produce nitrogen from compressed air. Nitrogen making machines are widely used in the electronics industry, heat treatment, food industry, coal industry, chemical industry, petroleum and natural gas industry, pharmaceutical industry, cable industry, metallurgical industry, rubber industry, aerospace industry and so on.

 Purification of 99.9995% nitrogen making machine by carbon loading
1. Characteristics of carbon purifier nitrogen making machine: customizable carbon purifier, air separation unit, air purifier, nitrogen making machine. Technical characteristics: this series of products use carbon loaded catalyst to deoxygenate, without consuming hydrogen gas source. Carbon and nitrogen in the reaction of oxygen to generate carbon dioxide, and then use the pressure swing adsorption process to remove carbon dioxide and water, after filtration to obtain high purity.

 Purification of 99.9997% nitrogen making machine by hydrogenation
1. The characteristics of hydrogen purification and nitrogen making machine: it can be customized by PSA or membrane system. After mixing with a small amount of hydrogen, the residual oxygen in the reactor filled with metal palladium catalyst will react with hydrogen to form water vapor. After that, most of the steam will be condensed through a cooler, and then the condensate can be removed by the high efficiency water separator.

First, about nitrogen nitrogen, the chemical formula is N2, usually a colorless and odorless gas, and generally nitrogen is smaller than air density. Nitrogen accounts for 78.08% of the total volume of air, and is one of the main components of air. At standard atmospheric pressure, nitrogen is cooled to -195.8 C and becomes colorless liquid, cooled to -209.8 C.
