Principles and characteristics of argon gas purifier

The utility model relates to an argon purifier, which is a device for purifying argon gas, consisting of a casing, an inlet and outlet pipe, a purification column, a filter, a valve and an instrument. Different purification columns divide the machine equipment into several purification chambers, and when used, argon passes through different purification columns to remove impurities in them according to the reaction and adsorption of gas with catalysts and adsorbents. These adsorbed impurities need to be removed periodically before they can be used again. So what is the principle and characteristics of the argon purifier? Let's take a look at it.

1.Principle of Argon Purifier

The argon purifier must use argon as carrier gas when the equipment starts to purify, and the argon is purified through the argon purifier until the high purity argon is output. The argon gas is heated to 500 ° C in a purification tower with a noble metal getter, where it undergoes chemical changes to remove oxygen and nitrogen, and the remaining carbon dioxide and water are removed as it passes through a molecular sieve. The precious metal getter and molecular sieve are respectively installed in a section of stainless steel pipe to form "getter tube" and "molecular sieve tube." Finally, the precious metal getter and molecular sieve will be consumed, and the purification efficiency will be reduced. The customer must replace this pipe.

II. Characteristics of Argon Purifier

1, strong purification ability: argon purifier can purify low purity argon, the larger total flow rate is 30L / minute, the purification effect is stronger when the total flow rate is low. Residues that can be removed such as CO2, N2, carbon monoxide, nitrogen oxides, carbon dioxide, and water (generally purifying impurities in the 300-500 ppm range) have a total impurity concentration as low as 1 ppm.

2, simple operation: fully automated operation can save time, avoid human intervention and the possibility of misuse, improve reliability.

3, application safety: regeneration does not require hydrogen, nor does it require vacuum and equipment with common fault alarm, safe and reliable.

4, low maintenance cost: the use of modular rapid replacement purifier tube program process.

5, stability: not affected by room temperature and current changes, to maintain long-term performance stability.

6, coordination ability: equipped with a gas sensor to display the working pressure of the equipment and automatically turn off the pressure relief of the equipment when the overpressure occurs, with online monitoring and system diagnosis functions.
