Vertical and spiral-wound membrane vibration filtering device

Abstract

The invention discloses a vertical and spiral-wound membrane vibration filtering device. The filtering device comprises a vibration component and a membrane component; the vibration component is mounted on a bracket through an elastic mechanism; the membrane component is directly and rigidly mounted in the vibration component; the membrane component is elastically connected with the bracket, and can damage the crystallization condition of easily-scaled substance and reduce a retention layer of the membrane surface under the acting force of left-right, up-down or multiple vibration of the vibration component, thereby increasing the membrane surface shearing force, the pollutant is hard to stock on the membrane surface and in the water inlet channel, and the filter membrane is prevented from being blocked; the membrane component is directly mounted on the vibration component, the vibration efficiency is high, the effect is good, and the membrane processing efficiency is further improved; and meanwhile, excessive flushing and chemical cleaning on the device are avoided, so that the service life of the spiral-wound element is longer, and the operation cost of the device is reduced.

Description

technical field [0001] The invention relates to the field of membrane filtration equipment, in particular to a vertical roll-type membrane vibration filtration device. Background technique [0002] Membrane separation technology refers to the technology of separating the components in the mixture by using the selective permeability of the membrane under the action of driving force. Membrane separation technology is widely used in environmental protection, food and beverage, pharmaceutical, chemical and other fields. In today's human society vigorously advocating and effectively implementing the trend of energy conservation, emission reduction and circular economy, the application of membrane technology in material separation and water treatment will become more prominent. Membrane separation is roughly divided into hollow fiber, tubular membrane, plate membrane and roll membrane according to the shape of the membrane module. Roll-type membrane has the largest application v...

Problems solved by technology

In the prior art, there are mainly two ways to arrange the roll-type membrane: one is to arrange the roll-type membrane horizontally, and the effective and low-cost air-water cleaning method cannot be applied, because even if a small amount of gas enters the membrane module during operation, it will cause The gas concentrates on the upper part of the membrane element and causes damage to the membrane element; the other uses a vertically distributed roll-type membrane, such as the patent number 201521041537.9, and the patent name is "a vibrating vertical roll-type membrane filtration device". Membrane filtration device, the membrane module is placed upright, and the micro-bubbles formed by air and water are used to clean the membrane surface more effectively, and a vibration component is installed. Under the vibration force of the vibration component, the pollutants on the membrane surface and It is not easy to accumulate in the water inlet channel, because the conditions for forming crystals are destroyed, which greatly reduces the crystallization and prevents the filter membrane from being clogged. However, the membrane components of this device are installed on the bracket through the vibration transmission device, and the vibration component drives the bracket Vibration, the bracket transmits the vibration to the membrane assembly through the vibration transmission device, the transmission loss is large, the vibration efficiency is low, and the vibration effect is not good
