Split oxygen production adsorption unit with silencing function

Abstract

The invention provides a split oxygen production adsorption unit with silencing function which comprises a silencing unit, a molecular sieve set, two molecular sieve set inlet / outlet pipes, a nitrogen discharge pipe, a solenoid valve and a nitrogen discharge silencer, wherein the molecular sieve set inlet / outlet pipes, solenoid valve, nitrogen discharge pipe and nitrogen discharge silencer are arranged in the silencing unit; one end of the solenoid valve is connected with one end of each molecular sieve set inlet / outlet pipe, and the other end is connected with one end of the nitrogen discharge pipe; the other end of each molecular sieve set inlet / outlet pipe is connected with the molecular sieve set; and the other end of the nitrogen discharge pipe is connected with the nitrogen discharge silencer. The oxygen production adsorption unit solves the problem of noises generated by instantaneous release of high-pressure gas inside the solenoid valve and the molecular sieve set inlet / outlet pipes, also solves the problem of noises generated by the nitrogen discharge silencer in the nitrogen discharge process, and improves the oxygen production system on the market, thereby well solving the problem of noises.

Description

Technical field [0001] The invention relates to an oxygen-making adsorption device, in particular to a split oxygen-making adsorption device with sound-absorbing function. Background technique [0002] The oxygen generator generally includes two molecular sieve cylinders, an oxygen storage cylinder and a solenoid valve. The two molecular sieve cylinders are connected through a pipeline. The oxygen storage cylinder is connected to the two molecular sieve cylinders through the pipeline. The solenoid valve is located at one end of the two molecular sieve cylinders. It is connected with two molecular sieve cylinders through pipelines. [0003] At present, the oxygen production system on the market is generally divided into two types: the molecular sieve group in the first oxygen production system is composed of 6 main components integrated in one piece: 2 adsorption towers, 1 gas storage tank, and 1 upper cover , 1 base, 1 solenoid valve; the molecular sieve group in the second oxygen...
