Noise elimination and reduction device for molecular sieve oxygenerator

Technical Field

The utility model belongs to the technical field of the oxygenerator, concretely relates to molecular sieve oxygenerator is with eliminating noise device of making an uproar.

Background

The common oxygen generator has the working principle that air is injected into a closed container filled with molecular sieves by utilizing the characteristic that the molecular sieves selectively adsorb nitrogen, and the pressure in the container is increased along with the air. At this time, the molecular sieve absorbs a large amount of nitrogen in the air with the increase of the ambient pressure, and the oxygen in the air still exists in a gas form and is collected through a certain pipeline. This process is commonly referred to as the "adsorption" process. When the molecular sieve in the container adsorbs nitrogen to a certain degree, the container is exhausted and decompressed, the capacity of the molecular sieve for adsorbing nitrogen is reduced along with the reduction of the environmental pressure, and the nitrogen is released from the inside of the molecular sieve and is discharged as waste gas. This process is commonly referred to as "desorption". The molecular sieve oxygen generation equipment adopts two molecular sieve containers in order to ensure the continuous and stable output of oxygen, and the container 2 is in the desorption process while the container 1 is in the adsorption process by control, and vice versa. The compressor runs at a high speed to drive the two pistons to circularly suck air, and the flow rate of the air entering the compressor is high, so that high-frequency airflow sound is generated under the state that the two pistons are switched at a high speed. Therefore, the noise elimination and reduction device for the molecular sieve oxygen generator is needed to solve the problems.
