Description

Sewage inlet and outlet connecting pipe for DTRO membrane assembly

Technical Field

The utility model relates to a dish tubular reverse osmosis membrane subassembly technical field, more specifically relate to a sewage business turn over is taken over for DTRO membrane module.

Background

The technology of the disc-tube type reverse osmosis membrane, DTRO for short, is sourced from Germany, is firstly developed and developed by the company PALL ROCHEM in Germany and is applied to the field of landfill leachate and high-concentration industrial wastewater treatment in 1987, the membrane technology is considered to be the most effective technology for treating the landfill leachate and the high-concentration industrial wastewater in the world, and the DTRO technology is introduced from Europe in 2003 in China and is successfully applied to the treatment of the landfill leachate. The DTRO disc tube type reverse osmosis membrane component mainly comprises an RO membrane, a flow guide disc, a central pull rod, a shell, end covers at two ends, various sealing elements, a connecting bolt and the like, wherein feed liquid enters the flow guide disc at the bottom through a flow guide channel after passing through a gap between a membrane stack and the shell through a water inlet pipeline, the treated liquid rapidly flows through a filtering membrane at the shortest distance, then is reversely rotated to the other membrane surface by 180 degrees and then flows into the next filtering membrane, so that the tangential flow filtration from the periphery of the flow guide disc to the center of the circle is formed on the surface of the membrane, concentrated liquid finally flows out from a water outlet pipe at a flange at a feed end, meanwhile, the permeate liquid is continuously discharged through a central collecting pipe, and the concentrated liquid and the permeate liquid are isolated through an O-shaped.

The joint pipe positions of a water inlet pipe, a water outlet pipe and an end cover in the conventional DTRO disc-tube type reverse osmosis membrane component have insufficient sealing effect, the phenomenon of water leakage often occurs, and the DTRO disc-tube type reverse osmosis membrane component is often applied to high-pressure liquid, so the strength of the joint pipe positions of the water inlet pipe, the water outlet pipe and the end cover is required to be improved.
