Embodiment 1

[0042] 1. Insert 37 PP tubular membranes 7 with an outer diameter of 6.0mm, a wall thickness of 1.0mm, a pore diameter of 0.1μm, a porosity of 65%, and a length of 500mm into the orifice plate 6 of the same material. The diameter of the inner hole of the orifice plate 6 is 6.1mm, thickness is 15mm.

[0043] 2. Clamp the tubular membrane-orifice plate combination obtained in step 1 on the welding chuck, and keep the end surface of the orifice plate 6 horizontal; set a baffle at the other end of the tubular membrane 7 to keep one end of the tubular membrane 7 and the orifice plate The end face of 6 is flush and prevents tubular membrane 7 from falling off from orifice plate 6.

Abstract

The invention relates to an organic tubular membrane contactor. An organic tubular membrane with a large diameter and high mechanical strength is welded to an orifice plate at a certain distance, and then the orifice plate and the membrane shell are welded or mechanically fastened to form a high-efficiency , Stable membrane contactor. The present invention also relates to a preparation method of an organic tubular membrane contactor, which generates sufficiently high welding pressure in a short period of time through an active down-pressing hot-melt welding method, and places the tubular membrane in a clearance fit manner, The orifice plate and other contact parts provide a discharge channel for the gas released by the heating and collapse of the film, which greatly improves the success rate of welding and simplifies the welding equipment.

Description

technical field [0001] The invention relates to the technical field of membrane separation, and more specifically relates to an organic tubular membrane contactor and a manufacturing method thereof. Background technique [0002] In the field of membrane separation, membrane separation processes such as membrane distillation, membrane absorption, and membrane extraction have been more and more researched and applied. Membrane contactor is the core element for the realization of these membrane separation processes. It uses microporous membranes to separate the two fluids and completes the mass transfer process between the fluids through membrane holes. It is usually made of polypropylene (PP), polyethylene (PE ) and other hydrophobic hollow fiber membranes are made by bonding the membrane shell with epoxy resin or adhesive. However, materials such as PP and PE have poor bonding performance, and the prepared membrane contactor is easy to open and leak under the condition of or...
