Types and principles of industrial nitrogen generators

The main types of industrial nitrogen production: First, membrane air separation nitrogen production Using air as raw material, under pressure conditions, gases such as oxygen and nitrogen are used to have different permeation rates in the membrane to separate oxygen and nitrogen.

How does the nitrogen generator make nitrogen?

When the nitrogen generator manufactures nitrogen, due to the different diffusion rates of oxygen and nitrogen gas molecules on the surface of the molecular sieve, the diffusion rate of gas molecules (O2) with a smaller diameter is faster, more enters the micropores of carbon molecular sieve, and the diffusion rate of gas molecules (N2) with larger diameter is slower, and less enters the micropores of carbon molecular sieve. This selective adsorption difference between nitrogen and oxygen by carbon molecular sieve leads to oxygen enrichment in the adsorbed phase and nitrogen in the gas phase in a short period of time, so that oxygen and nitrogen are separated, and the gas phase enrichment nitrogen is obtained under PSA conditions. After a period of time, the adsorption of oxygen by molecular sieve reaches equilibrium, and according to the different characteristics of carbon molecular sieve adsorption capacity of adsorbed gas at different pressures, the pressure is reduced to make carbon molecular sieve release the adsorption of oxygen, which is a process that can be generated. Nitrogen can be collected in this way.

Precautions for Helium

Helium should be used on a first-in, first-out principle, use a trolley to move the container, do not pull, roll or slide the cylinder, do not try to grab the lid of the cylinder to lift it; The cylinder should be fixed during the whole process of use, and a pressure reducing regulating valve or independent control valve should be used to release gas from the cylinder, and a check valve should be used to prevent backflow; Do not heat the cylinder to increase the pressure and discharge, if the user has difficulty operating the cylinder valve, stop use; An adjustable wrench should be used to open the overly tight or rusty bonnet, and tools (such as wrenches, screwdrivers, crowbars, etc.) should not be inserted into the bonnet, otherwise the valve will be damaged and leakage; Helium is compatible with common materials, and pipelines and equipment are designed to meet the needs of pressure.

How to effectively extend the service life of the nitrogen generator?

1. In the normal work of the matching refrigeration dryer, wipe dryer and other machinery and equipment, be sure to complete the actual operation in accordance with the instructions for use. Whether the gas drying equipment is operating normally is important for the nitrogen production device.

How to deal with the phenomenon of dust spraying in the nitrogen generator?

The ash injection condition of the nitrogen generator, also known as carbon molecular sieve delamination, occurs because the carbon molecular sieve pressure is not tight or the carbon molecular sieve is loose.

National standards for various industrial gases

The national standards of various industrial gases are different, and only the industrial gases that meet the national standards can be regarded as qualified industrial gases. The following is a brief introduction to the standards of several commonly used industrial gases.

Trading volume, liquid argon market heating up significantly

Returning to the main markets, due to the different start-up speeds of downstream industries in various places, the speed of relief of inventory pressure is different, and the price upward is not synchronized. According to Figure 3, as a representative market in the western region, Inner Mongolia began to rise rapidly in early February, and the mainstream factory rose to 820-900 yuan / ton, which is mainly related to the support of monocrystalline silicon enterprises during the Spring Festival and demand increase; Jiangsu market as a representative market in East China, its downstream distribution is not concentrated, after the holiday manufacturers discharge warehouse pressure mainly, the price is mostly reflected in low prices to push up, until mid-February, with the rise in demand superimposed on the surrounding production enterprises spring maintenance, supply and demand increase, price upward acceleration, to the current mainstream factory to 1200-1400 yuan / ton; Guangdong market first fell and then rose, after the holiday by the surrounding low-price sources impact, the mainstream received goods first fell to about 750 yuan / ton, and then with the downstream market increase, and the surrounding low-price sources were consumed, the price opened a slow upward channel, but due to the current domestic and foreign economic operation pressure is still large, foreign trade business is still affected to a certain extent, Guangdong demand is relatively limited, the rise is relatively moderate, the current mainstream received to 1200-1350 yuan / ton.

The profits of steel enterprises have rebounded, helping the liquid oxygen market to run better

Recently, steel prices have been rising actively. As of February 23, the average closing price of the domestic steel billet market was 4,050 yuan/ton, an increase of 122 yuan/ton compared with the same period last week, and a month-on-month increase of 3.11%. Affected by the positive macro expectations, the overall performance of the steel market is positive, and the superimposed futures market has strengthened, and the market trading activity has increased, supporting the rise of steel products.
