Supporting flow guide plate and separation filtering membrane column device

Abstract

The invention discloses a supporting flow guide plate and a separation filtering membrane column device. The supporting flow guide plate is a disc with a central circular hole; a plurality of rings of flow blocking salient points are arranged on the disc; a radial rotational flow slit is also formed on the disc; one of two sides of the rotational flow slit of the disc upwarps to be extended into an upwarping part, and the other side is bent downwards to be extended into a lower bending part; and the upwarping part is parallel to the lower bending part. The separation filtering membrane column device comprises the supporting flow guide plate and a membrane; an inner pull rod for fixing the supporting flow guide plate and the membrane and upper and lower stacking plates are also installed in a bearing outer shell; a mounting hole is formed at the center of the membrane; a radial gap aligned with the rotational flow slit is also formed on the membrane; and an outer pull rod for supporting, tensioning and pressing upper and lower end cover flanges is installed outside the bearing outer shell. Compared with a traditional membrane component, the separation filtering membrane column device has the beneficial effects that the pressure loss is reduced by above 70 percent, and the product efficiency is improved. The separation filtering membrane column device is a special device with the advantages of antipollution and low energy consumption and is particularly suitable for an economical treatment process of a high-concentration fluid.

Description

technical field [0001] The invention belongs to the field of solid-liquid separation, and in particular relates to a filter device with a separation membrane as a medium. Background technique [0002] Membrane elements for fluid separation and filtration have similar properties and are prior art and widely patented. Although the traditional spiral-wound membrane element has a high filling area density, the system application has high requirements on the influent water quality and complicated pretreatment conditions. Because the organic pollutants, inorganic scaling substances and suspended particle impurities in the high-concentration fluid will easily block the screen of the membrane column, resulting in frequent shutdown and cleaning of the system, which will reduce the life of the membrane column and even fail to operate normally. [0003] The existing disc-type membrane column solves the above-mentioned anti-pollution problem of the membrane column. In fact, there is s...

Problems solved by technology

Although the traditional spiral-wound membrane element has a high filling area density, the system application requires high water quality and complicated pretreatment conditions.

Because the organic pollutants, inorganic scaling substances and suspended particle impurities in the high-concentration fluid will easily block the mesh of the membrane column, resulting in frequent shutdown and cleaning of the system, which will reduce the life of the membrane column and even fail to operate normally.

[0003] The existing disc-type membrane column solves the above-mentioned anti-pollution problem of the membrane column

In fact, there is still a special problem with the disc-type membrane column, that is, the disc-type membrane column used for nanofiltration, ultrafiltration and microfiltration will cause a large amount of pressure loss due to multiple violent reverse flows of the fluid, and the energy consumption of the system will be large, resulting in its inability to heavily promote the app
