Multi-tube pass inorganic separating membrane module

Abstract

The invention discloses a multi-tube pass inorganic separating membrane module, comprising tubular membrane tubes, faceplates, tube plates, a shell and close covers, wherein the external diameter of the faceplate is adapted to the internal diameter of the shell, the tube plate and the face plate are respectively provided with a plurality of holes, the tubular membrane tube passes through the holes on the two faceplates and tube plates and is placed on the faceplates and tube plates, and the tubular membrane tube is fixed between the tube plates; the close covers are hermetically connected with the left and right ends of the shell, and the close cover of one end of the shell is provided with a vacuum-pumping opening; at the two ends of the multi-tube pass inorganic separating membrane module, spaces between the tube plates and the faceplates form material split cavities, the lower portion which belongs to the shell and is corresponding to the material split cavity is provided with a feed inlet, the upper portion which belongs to the shell and is corresponding to the material split cavity is provided with a material liquid outlet, upper and lower ends of the tubular membrane tubes in the material split cavities are provided with infiltration pores, and baffle plates are arranged in the material split cavities at intervals; a thermal medium inlet is arranged on the upper portion of the shell and between the two faceplates, and a condensed water outlet is arranged at the bottom of the shell.

Description

technical field [0001] The invention relates to a multi-tube-pass inorganic separation membrane module for single-tube or multi-tube. Background technique [0002] Dehydration of organic solvents or dehydration of organic solvents in water is one of the hotspots in the field of membrane separation research. For more than ten years, the application of this technology to remove water in organic solvents or mixed solvents and to recover organic solvents from waste water and waste gas has become a new process technology, saving energy and reducing consumption in petrochemical and related industries, promoting traditional It has played an important role in the technological upgrading and transformation of the process, fully demonstrating its advantages and competitiveness as a "clean process". The dehydration and separation of organic solvents is driven by the partial pressure difference of the vapor of the components in the liquid (gas) mixture, and the separation process is re...
