Circular plate type super-filter

Abstract

The invention discloses a disk type millipore filter which comprises a barrel. The barrel is internally provided with a disk type millipore membrane component which comprises a contributing water pipe; the two ends of the barrel are respectively provided with barrel cover components. One barrel cover component is provided with a raw water inlet connection tube and a gas inlet connection tube; theother barrel cover component is provided with a sewage discharging connection tube and a gas discharging connection tube; the barrel cover components are also provided with a purified water outlet connection tube; the contributing water pipe is provided with a plurality of permeable holes; the two ends of the contributing water pipes are communicated with the purified water outlet connection tube. The pressure reduction of disk type membrane groups is small; membranes are difficult to damage and can be used for long term; the interfaces of membranes are provided with open-end free air space, thus having no dead angles and being easily to clean; the membrane surface is smooth; the filter can not be blocked, and has the characteristics of anti-chemical cleaning and non viscidity; once isolates and impurities accumulate on the membrane surface, the disk type millipore framework is only needed to be taken out and cleaned with clean water.

Description

【Technical field】 [0001] The invention relates to a disc type ultrafiltration membrane device for drinking water purification and liquid clarification filtration in the field of water treatment. 【technical background】 [0002] At present, most ultrafiltration membrane devices at home and abroad are made of hollow fiber ultrafiltration membranes. The shell of the hollow fiber ultrafiltration membrane device can be made of various materials such as ABS (acrylonitrile-butadiene-styrene copolymer), PMMA (polymethyl methacrylate), UPVC (rigid polyvinyl chloride) and so on. The device consists of a cylinder body and a cylinder cover bonded at the upper and lower ends. There is a raw water inlet connector on the upper cover, and a water outlet connector on the side. The design of the lower cover is basically the same as that of the upper cover, except that the raw water inlet connection on the upper end has become a water outlet connection. The cylinder cover is socket-bonded wit...

AI Technical Summary

Problems solved by technology

Due to the material and production reasons of the existing hollow fiber membrane device, there are the following disadvantages: ①The membrane wire is thin and easy to break, resulting in leakage

②The hollow fiber ultrafiltration membrane device needs pretreatment process, otherwise the hollow fiber membrane will be blocked, and the internal pressure type is more serious

③ It is difficult to clean the hollow fiber ultrafiltration membrane device after contamination
