A disc tube type reverse osmosis component

Abstract

The invention belongs to the field of water treatment equipment, and in particular relates to a dish-type reverse osmosis component, which includes a membrane shell, a membrane core inside the membrane shell, and upper and lower flanges at both ends of the membrane shell. Flow plate, one side of the guide plate is provided with a number of bumps and sealing ring grooves, the other side of the plate is welded with a reverse osmosis diaphragm, the sealing ring groove is equipped with an O-ring to seal the diaphragm, and two adjacent guide plates pass through The positioning bosses on the inner hole of the diversion plate are connected in a snap-fit ​​manner, and the inner holes of the superimposed diversion disc form a water production channel. The periphery of the diversion disc surface is an outer ring platform, and two gaps are opened in the outer ring platform. Through holes are provided on both sides of the shell corresponding to the two notches to form a water inlet and a concentrate outlet. The invention changes the water inflow and outflow modes of the existing dish-type reverse osmosis plate components, and changes the existing product structure, has stronger pollution resistance, greatly reduces the phenomenon of concentration polarization, and has a higher degree of integration.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, in particular to a disc tube type reverse osmosis component. Background technique [0002] At present, the basic structure of the disc tube type reverse osmosis flat membrane module is a membrane shell, the upper and lower flanges at both ends of the membrane shell, the central tie rod inside the membrane shell, and several diaphragms and guide plates installed on the central tie rod. Membrane core. Usually choose to open the water inlet at the bottom of the membrane shell, and the inlet water flows back and forth on the surface of the deflector plate under the pressure, and the water that passes through the membrane is the produced water, and the water that does not pass through the membrane is the concentrated solution, and the produced water and the concentrated solution It is discharged from the concentrated liquid outlet and the product water outlet opened on the top of the membrane...

AI Technical Summary

Problems solved by technology

This structure leads to a long flow from water inlet to water outlet, and the flow can reach tens of meters, so the membrane is easy to be polluted, resulting in obvious concentration polarization

On the other hand, the structure of the central tie rod cannot guarantee the internal preload of the membrane shell, and at the same time, there are a series of disadvantages that affect stability and economy, such as complicated installation and increased weight.
