Problems solved by technology

Since the adsorbent has the characteristic that its adsorption capacity changes with the pressure, changing its pressure can make the adsorption and desorption operation alternately, the traditional flow control structure for nitrogen and oxygen separation cannot automatically and accurately control the separation of nitrogen and oxygen mixed gas, resulting in output The gas fluctuates greatly and cannot output a stable flow of gas, so it continues to change

Abstract

The invention discloses a flow control structure of a nitrogen-oxygen separation device, and relates to the technical field of oxygen generators, the flow control structure comprises a pipeline, the pipeline is composed of a conical section, a monitoring section and a control section, and the conical section, the monitoring section and the control section are integrally formed; the flow monitoring assembly is arranged on the monitoring section and is used for monitoring the gas flow in the monitoring section; the flow control assembly is arranged on the control section and used for controlling the gas flow in the control section. The transmission assembly is connected with the flow monitoring assembly and the flow control assembly and used for converting flow changes monitored by the flow monitoring assembly into flow control of the flow control assembly. The conical section, the monitoring section and the control section are arranged on the pipeline, and the conical section plays a role in reducing the pipe diameter, so that the pipe diameters at the monitoring section and the control section are reduced, and the flow is conveniently monitored and controlled.

Description

technical field [0001] The invention relates to the technical field of oxygen generators, in particular to a flow control structure of a nitrogen and oxygen separation device. Background technique [0002] Oxygen concentrator is a kind of machine for producing oxygen. Its principle is to use air separation technology. Using the adsorption properties of molecular sieves, through physical principles, a large-displacement oil-free compressor is used as the power to separate nitrogen and oxygen in the air, and finally obtain high-concentration oxygen. This type of oxygen generator produces oxygen quickly and has a high oxygen concentration, and is suitable for oxygen therapy and oxygen health care for various groups of people. Since the adsorbent has the characteristic that its adsorption capacity changes with the pressure, changing its pressure can make the adsorption and desorption operation alternately, the traditional flow control structure for nitrogen and oxygen separatio...
