Synthesis device for economic molecular sieve membrane

Abstract

The invention relates to a synthesis device for an economic molecular sieve membrane. The prior art is improved for circulating a membrane casting solution in a crystallization process to the outsideof a synthesis kettle, and a reasonable valve is arranged for controlling the volume of the membrane casting solution which enters a sedimentation kettle and the membrane casting solution of the corresponding time quantum, so that the sedimentation effect is the best on the basis of guaranteeing the crystallization effect.

Description

technical field

[0001] The invention relates to a membrane synthesis device, in particular to a Silicalite-1 molecular sieve membrane synthesis device. Background technique

[0002] Membrane separation technology is a new separation technology that emerged rapidly after the 1960s. It has the functions of separation, concentration, purification and refinement, as well as high efficiency, energy saving, environmental protection, molecular level filtration and simple filtration process, easy to control, etc. Features, which have been widely used in many fields at present, have produced huge economic and social benefits, and have become one of the most important means in today's separation science. As a kind of inorganic membrane, molecular sieve membrane has better thermal and chemical stability than organic membrane, and has great application potential in the fields of organic solvent / water separation and gas separation, while Silicalite-1 molecular sieve membrane is relativel...
