PLATE FRAME TYPE GAS SEPARATION MEMBRANE MODULE FOR REMOVAL AND RECOVERY OF VOLATILE ORGANIC COMPOUNDS AND VAPOR

摘要

The present invention is a plate-type gas separation membrane that can be used to separate or recover these gases from a large volume source of VOCs or harmful gas sources such as CO ₂ , SOx, NOx, and specific gas mixtures through an efficient membrane separation process. It is about a module. More specifically, the present invention provides a gas separation membrane module for efficiently separating or recovering these gases through a membrane separation process from a large source of VOCs or harmful gas sources such as CO ₂ , SOx, NOx or the like, which are released into the atmosphere. At the front end, the gas mixture is zigzagly formed into the partition walls to maximize the gas recovery rate by maximizing the contact area between the gas mixture and the gas separation membrane outside the unit cell, and to minimize the performance degradation of the gas separation membrane due to the concentration polarization. There are a number of unit cells installed at fixed intervals, and the rear end forms each unit cell somewhat larger, so that the side passage between the inner wall of the case and the unit cell is completely sealed, and one side of the gas mixture on one side of the unit cell deviates from the center. Designed to be placed in a zigzag It is formed to maintain the contact time between the gas to be recovered and the gas separation membrane as long as possible, and is connected to a vacuum pump and a tube of a predetermined thickness in the center of the outer case at the rear of the gas separation membrane module to suck VOCs contained in the gas mixture, and at the center On one side of the off-side has a feature to implement a plate-type gas separation membrane module having a configuration that is provided with a discharge port for discharging the gas contained in the gas mixture to the outside and greatly improved the removal or recovery of the predetermined substance from the gas mixture.;Plate Type Gas Separation Membrane Module, Unit Cell
