Immersed ultrafiltration membrane equipment with high integration level

Abstract

The invention belongs to the field of membrane assemblies, and particularly relates to high-integration-level immersed ultrafiltration membrane equipment, which comprises a bracket and a plurality ofultrafiltration membrane assemblies symmetrically arranged in two rows, wherein the ultrafiltration membrane assembly comprises a shell and a membrane tow arranged in the shell, one end of the membrane tow is a water production end, the other end of the membrane tow is a closed end, a water production box is arranged at the water production end, an aeration box is arranged at the closed end, a fixing resin is arranged in the water production box and is used for fixing the membrane tow, a water production port communicated with the water production box is formed in the top of the water production box, the water production port is connected with a connecting elbow through a valve, a water production elbow is connected with a water production main pipe through an anti-loose joint, an aerationpipe groove matched with an aeration branch pipe is formed in the aeration box, and the aeration branch pipe can be inserted into the aeration pipe groove to position the ultrafiltration membrane assembly. Due to the fact that the aeration branch pipe below the single ultrafiltration membrane assembly is connected with the ultrafiltration membrane assembly in a pluggable mode, when the ultrafiltration membrane assembly is replaced and maintained, the requirements for in-situ replacement and after-sales repair of the membrane assembly can be met after the liquid level is lowered.

Description

technical field [0001] The invention belongs to the field of membrane modules, in particular to a highly integrated submerged ultrafiltration membrane equipment. Background technique [0002] The submerged ultrafiltration device takes the integrated module of the submerged ultrafiltration membrane module (hereinafter referred to as: submerged ultrafiltration machine) as the central processing unit, equipped with specially designed water pumps, pipelines, valves, cleaning units, dosing units and Automatic control unit, etc., forming a closed-circuit continuous operation ultrafiltration system. When the membrane produces water, the raw water is filtered through the ultrafiltration membrane under the negative pressure suction of the water production pump to achieve the purpose of physical separation and purification. [0003] In the traditional design, the submerged ultra / microfiltration membrane module is mostly in the form of a curtain membrane module. In view of its structu...

Problems solved by technology

At the same time, due to the high-density arrangement, the distance between the membrane modules is small, and the membrane modules can only be disassembled from one end of the membrane equipment; the overall structure is complex, the workload is heavy, the product requires more mold parts, the processing is difficult, and the later maintenance is difficult
