Double-column self-control variable-pressure adsorption experiment system with self-pressurization system

Abstract

The invention provides a double strut automatic control transformation adsorption experimental system with a self pressure charging system. The output end of a material supply device of the double strut automatic control transformation adsorption experimental system is connected with the input end of an adsorptive separation device thereof. The output end of the adsorptive separation device is connected with the input end of a product accumulation device. The adsorption column of the adsorptive separation device comprises a double adsorption column, a magnet valve set, a temperature pickup, a pressure pickup and a precision pressure gauge. The material supply device comprises at least two sets of raw material gas tanks, gas distributing tanks connected with the raw material gas tanks by a pipeline and a gas feed pressuring cylinder P1. All gas distributing tanks are connected by junction valves. The product accumulation device comprises a product tank and a product gas pressuring cylinder P2. A control system controls the opening and closing of the magnetic vale and the pressuring cylinder of each pipeline in the raw material supply device, the adsorptive separation device and the product accumulation device by the computer program so as to realize the separation and purification on gas. The double strut automatic control transformation adsorption experimental system is mainly used for simulating the industrial adsorption and separation process in a laboratory and provides the reference for industrial adsorption separation application data and process flow.

Description

technical field [0001] The invention relates to gas adsorption and separation equipment used in laboratories or small and medium-sized experiments, in particular to a double-column automatic control pressure swing adsorption (PSA) experimental system with a self-pressurization system. Background technique [0002] Pressure swing adsorption (referred to as PSA) is a new gas separation technology. Its principle is to separate the gas mixture by using the difference in the "adsorption" performance of different gas molecules by adsorbents such as molecular sieves. PSA has the characteristics of simple operation and high energy efficiency, and is increasingly used in the separation and purification of bulk gases in industry. At present, there are many PSA equipment and methods for gas adsorption and separation in industry, such as Chinese patents CN1432424 (vacuum pressure swing adsorption equipment), CN1449860 (method and device for improving pressure swing adsorption gas separa...

AI Technical Summary

Problems solved by technology

This traditional method is difficult to involve the comprehensive influence of pressure, temperature and other conditions on the PSA process

[0003] In summary, there is no special experimental equipment for this research in the prior art, and the PSA device or method used in industry is obviously unable to meet the needs of laboratory research and analysis of experimental parameters due to its bulky size and high cost of use.
