Multi-component organic-gas pressure-changing adsorption and realtime detection-control experiment device

Abstract

The present invention discloses a multicomponent organic gas pressure swing adsorption and real time test control experiment equipment. It is characterized by that the outlet place of its drying column is divided into three lines, first line is directly connected with gas inlet positioned in the upper end of pressure swing adsorption column; second line is connected with gas inlet of gas mixing column; and third line is connected with gas inlet of gas mixing column by means of organic gas generator and miniature packed column. The outlet of the gas mixing column is connected with gas inlet positioned in the lower end of the pressure swing adsorption column. The upper portion of every pressure swing adsorption column is equipped with three or more than three gas sampling units and temperature sampling units correspondent to said gas sampling units, its middle portion is equipped with a pressure sampling unit, and its lower end is equipped with two or more than two second temperature sampling units. The gas sampling unit is connected with a gas chromatograph and the pressure sampling unit and temperature sampling unit are connected with a temperature and pressure digital collection system.

Description

technical field [0001] The invention mainly relates to air pollution control equipment in the field of environmental protection, in particular to a multi-component organic gas pressure swing adsorption and real-time test control experimental device. Background technique [0002] In many industries of painting, printing, shoemaking and chemical production, the production process of some industrial products is accompanied by a large amount of volatile compounds (VOC S ) Exhaust gas discharge. Volatile organic compound emissions can be harmful to human health and animal and plant growth. As people's requirements for quality of life continue to improve, the country has also adopted stricter control measures for air pollution. The treatment of volatile organic gases, which were rarely paid attention to before, will become a focus of air pollution control. on VOC emissions S In general, there are many kinds of process technologies that can be applied to the treatment of waste ...
