Description

Technical Field

[0001] The utility model belongs to oxygen making machine equipment, in particular to a gas collecting cover plate and a separator. Background Art

[0002] The molecular sieve oxygen production system is a commonly used industrial oxygen production equipment that achieves nitrogen and oxygen separation through the molecular sieve adsorption principle. Its working principle is that the raw air is pressurized by the compressor, passes through the air pretreatment device to remove solid impurities such as oil and dust, and water, and then enters the adsorption tower equipped with molecular sieves. Nitrogen, carbon dioxide, etc. in the air are adsorbed by the molecular sieve, thereby obtaining high-purity oxygen.

[0003] In the prior art, the molecular sieve is placed in the separator. At the same time, in order to prevent the molecular sieve from contacting the outside world, cover plates are provided at both ends of the separator. A gas collecting pipe is provided on the side of the cover plate facing away from the separator; a main line and several branches are provided in the gas collecting pipe. Each branch is connected to the corresponding cover plate. The oxygen generated in multiple separators passes through the cover plate and enters the branch of the gas collecting pipe. After merging in the gas collecting pipe, it enters the oxygen tank along the main line of the gas collecting pipe. Since a separate gas collecting pipe needs to be provided on the separator, the molecular sieve oxygen production system has a complex structure and occupies a large space. Moreover, the cover plates need to be separately connected to the separator and the gas collecting pipe, which poses a high risk of gas leakage. Utility Model Content
