Description

Technical Field

[0001] The utility model relates to the technical field of molecular sieve adsorbers, in particular to a horizontal molecular sieve adsorber. Background Art

[0002] In addition to oxygen, nitrogen and argon, there are also small amounts of water vapor, carbon dioxide, acetylene and other hydrocarbon gases in the air. The water vapor content in the air is about 4-40g / m3 (varies with climate and region), the carbon dioxide content is about 0.6-0.9g / m3 (affected by altitude), and the acetylene content is about 0.01-0.1cm3 / m3. Although the content of these impurities in each cubic meter of air is not large, since the air separation equipment needs to continuously inhale air, these impurities will cause damage to the air separation equipment over time. The frozen water and carbon dioxide are deposited in the cryogenic heat exchanger, turbine expander or distillation tower, and will also block pipes and valves. Acetylene accumulates in liquid oxygen and there is a risk of explosion. In order to ensure the long-term safe and reliable operation of the air separation equipment, a molecular sieve adsorber must be installed to remove these impurities.

[0003] The existing molecular sieve adsorber needs to replace the molecular sieve inside after use. The general replacement method is to open the entire device shell, then disassemble the interior, and finally replace the molecular sieve. The operation is cumbersome, the replacement is inconvenient, and the operation time is long, requiring a long time of downtime, which affects the adsorption efficiency of the molecular sieve; the existing molecular sieve adsorption filters are generally connected between devices through metal tubes. In order to ensure the stability of the connection between the metal tubes, they are generally connected by threaded rotation. It is not possible to remove a single metal tube in the middle. When the entire molecular sieve adsorption device needs to be removed for maintenance, the entire metal pipeline connected to the molecular sieve adsorber needs to be removed before the molecular sieve adsorber can be removed. The process is cumbersome and inconvenient to maintain the molecular sieve adsorber as a whole.

[0004] Therefore, we proposed a horizontal molecular sieve adsorber to solve the above problems. Utility Model Content
