specific Embodiment

[0051] In this embodiment, the specific process steps are as follows:

[0052] Such as figure 1 and Figure 4 As shown, the unseparated compressed mixed gas enters the vortex tube nozzle 2 through the flow regulating valve 1, the pressure of the compressed gas in the nozzle 2 decreases and the speed increases, and after the speed of the separated gas increases, it enters the vortex chamber 33 along the tangential direction at a high speed. And a free vortex is formed in the vortex chamber 33, which is separated into two parts with different temperatures through kinetic energy exchange. The kinetic energy of the central part decreases to become low-temperature gas and flows into the vortex tube cold pipe 25 ; the kinetic energy of the edge part increases to become high-temperature gas and flows into the vortex tube heat pipe 4 .

[0053] Such as figure 1 and figure 2 As shown, the high-temperature gas flowing out from the vortex tube heat pipe 4 enters the heat channel 26 ...

Abstract

The invention discloses a gas separating system based on a micro / nanoscale thermal transpiration effect and a macroscopic eddy current cold and hot effect. The system comprises a flow rate regulating valve, an eddy current pipe, a thermal transpiration type gas separating device, a gas collecting tank, a first pressure regulating valve, a gas mixing tank, a second pressure regulating valve and the like. Compared with the prior art, the gas separating system has the advantages that firstly, a liquid absorbent regeneration system is not required, a solid absorbent regeneration system is also not required, and the gas separating system is low in energy consumption, is simple in system process, and can run continuously; secondly, multiple gas products can be obtained by adjusting the running condition; the gas separating system is low in cost, is rapid to start, and is easy to operate and regulate.

Description

technical field [0001] The invention belongs to the field of gas separation, in particular to a gas separation system based on micro / nano-scale heat flow effects and macroscopic eddy current cold and heat effects. Background technique [0002] Gas separation technology is more and more widely used in industry, medical treatment, aerospace, scientific research and other fields, such as separation and preparation of oxygen-enriched and nitrogen-enriched air from air, waste gas treatment in some industrial production processes, etc. At present, the most widely used gas separation methods mainly include gas absorption separation method, gas adsorption separation method, gas membrane separation method, and gas low temperature separation method. The gas absorption separation method is widely used in industrial waste gas treatment due to its characteristics of high absorption rate and absorption speed, large waste gas treatment capacity, and low pollutant concentration. However, t...
