Nitrogen recovery system application and principle

In order to save the cost of nitrogen and reduce the energy consumption often, nitrogen recovery is used.

Nitrogen recovery system is a supporting equipment, the recovery system takes the used nitrogen as raw material, removes dust, water and other impurities through dust removal, cooling, pressurization and adsorption drying processes, so as to obtain a higher purity of the finished gas to meet the needs of production process, and then replenish part of the fresh nitrogen, so as to make it used repeatedly.

Pressure balance and stability of nitrogen recovery system: Through the frequency conversion control of Roots fan and pressure control valves at all levels, combined with the company's pressure regulation, balance and control technology, the pressure of raw gas, recovery system pressure and using gas pressure can be kept stable.

High degree of automation of nitrogen recovery system, terminal upper computer operating system, fully automatic unattended control: pure gas flow, nitrogen dew point, oxygen content, system pressure, temperature and other displays, alarms and historical curves.

Nitrogen recovery system equipment process configuration characteristics

Nitrogen recovery system is a cost-effective gas recovery and purification equipment, the system in the drying and purification, automatic control and monitoring, system matching and system balance and stability of the company's gases are reflected in the proprietary technology.

System pressure stabilization: Through pressure adjustment, balancing and control technology, the raw gas pressure, recovery system pressure and using gas pressure are kept stable.

The newly designed automatic drainage device ensures “zero discharge” of nitrogen, which saves money for the customers and reduces the workload of the staff and unnecessary operation errors.

The Roots fan of the recovery system is made of stable and reliable products, and adopts frequency conversion control, so that the rotational speed of the fan will be automatically adjusted according to the actual processing gas volume. This can not only improve the stability of the system pressure, but also prolong the service life of the fan, and at the same time, when using a small amount of gas, it can achieve the effect of saving electricity.

Adopting multi-stage filtration, it can fully remove water, dust and oil, and at the same time, it can remove the oil and organic components that may be brought into the system.

More characteristics in the purification and drying device: the dryer adopts multi-tower type, deep adsorption of water, . The molecular sieve is fully regenerated through the molecular sieve, so that the molecular sieve is used for a long time. The structure of the external heating airflow, avoiding the molecular sieve local overheating, so that the molecular sieve in the dryer is heated uniformly, making a greater reduction in energy consumption, greatly extending the service life of the molecular sieve.

In terms of molecular sieve, our company and the international level of molecular sieve manufacturers have good relations of cooperation, according to our company in the purifier of authority and experience, according to our company's mature process requirements customized special structure and shape of the molecular sieve. Thus reflecting the uniqueness of our company.

Valve selection of sealing and trace dust adaptability of high temperature pneumatic butterfly valves, Germany BURKET solenoid valve, pure gas metal float flowmeter selection of Chengde Hot River Cronin products, to ensure that the system operates reliably.

High degree of automation, easy to operate, the entire system for computer monitoring: pure gas flow, nitrogen dew point, oxygen content, system pressure, temperature display, alarm and curve.

Environmental protection: no emission of three wastes, no environmental pollution; the regenerated purge gas of the system is returned to the front stage and then recycled into the system for product production.
