Hot-blowing dehumidification mechanism for oxygenerator

Abstract

The invention discloses a hot-blowing dehumidification mechanism for an oxygenerator. An air inlet is formed in the upper tank wall of a centrifugal separation tank, a gas collector is arranged at thelower part in the centrifugal separation tank, an inlet of a gas outlet pipe is connected with an outlet of the gas collector, a drying agent module is arranged in an air guide cylinder, and the lower end of the centrifugal separation tank is communicated with the cylinder wall of the air guide cylinder; an air inlet of a compressor air outlet guide cylinder is arranged beside a compressor of theoxygenerator, a through hole is formed in the cylinder wall of the compressor air outlet guide cylinder, the compressor air outlet guide cylinder is communicated with the first end of the hot air pipe through the through hole, and the second end of the hot air pipe is communicated with the first end of the air guide cylinder. The hot-blowing dehumidification mechanism has a good dehumidificationeffect, a water storage barrel does not need to be placed, and water in the water storage barrel does not need to be poured out regularly or irregularly, so that the problems of time and labor waste,potential safety hazards and the like caused by subsequent manual water separation are solved, and the service life of the oxygenerator is prolonged; and meanwhile, special interfaces do not need to be arranged, so that machining is convenient, and attractiveness is facilitated.

Description

technical field [0001] The invention relates to an oxygen dehumidification mechanism of an oxygen generator, in particular to a hot blowing dehumidification mechanism of an oxygen generator. Background technique [0002] The oxygen generator using the molecular sieve pressure swing adsorption principle generally needs to remove the moisture in the compressed air in the front section of the molecular sieve, otherwise the molecular sieve will reduce the strength of the molecular sieve after absorbing the moisture in the air. Under the alternating pressure inside the molecular sieve cylinder, the molecular sieve It will be powdered quickly and greatly reduce the life of the oxygen generator. At the same time, when the produced oxygen has a high water content, it will also cause corrosion damage to the inner wall of the gas storage cylinder. [0003] In addition, for the medical oxygen produced by the small oxygen generator, the national standard has strict standards for the wa...

Problems solved by technology

[0006] The above-mentioned traditional centrifugal dehumidification method avoids the problem that the adsorbent cannot continue to absorb water after it is saturated, but it has the following defects: on the one hand, it needs to connect the water storage tank below the centrifugal separation tank, which not only takes up space, but also requires a special interface to Matching increases the difficulty of processing and affects the appearance; on the other hand, more importantly, it needs to be taken out when the water storage tank is about to be full, which is not only time-consuming and laborious, but also easily leads to leakage in the water storage tank due to forgetting or early water filling. Water overflows, causing corrosion damage to equipment, electric leakage and safety accidents and other consequences
