Description

A membrane module adapter

technical field

The present invention relates to the technical field of membrane systems, in particular to a membrane module adapter.

Background technique

Membrane technology, as the most ideal technology for industrial sewage upgrading and emission reduction, is also gradually adapting to the needs of the market. There are more and more high-concentration and zero-emission projects. As the water recovery rate increases, the working pressure of the membrane system is also getting higher and higher. Taking the reverse osmosis membrane system as an example, the working pressure was usually within 15bar in the past, and the seawater desalination membrane system with the highest working pressure only reached 55bar. However, according to the current technical requirements, in order to minimize the amount of water evaporated at the end, it is often necessary to concentrate the brine to a level of 10-12%, and the system working pressure at this time will reach at least 90 bar. In individual ultra-high pressure concentration equipment, the designed working pressure has reached the level of 120bar.

In order to cope with the higher working pressure, each component of the membrane system needs to be redesigned to adapt to the ultra-high pressure working environment. Among them, the membrane module adapter is used to connect the membrane element and the external dialysis water pipeline, so that the dialysis water of the membrane element can flow out smoothly. At the same time, this component must withstand the working pressure of the system, and has a very high requirement on its strength. The current membrane shell manufacturers The method of increasing the wall thickness is adopted, although the pressure resistance requirements are met, but the water production is limited.
