Description

A detachable column membrane module

【Technical field】

The utility model relates to water treatment equipment. More specifically, the utility model relates to an internal detachable membrane module, which can be used for reuse of reclaimed water and production of purified water.

【Background technique】

In recent years, with the development of the membrane industry, more and more applications of membrane technology have attracted people's attention. Hollow fiber membrane modules have been widely used in many fields such as sewage treatment and wastewater reuse due to their unique structural characteristics, such as high packing density and self-supporting system. However, especially for high turbidity water treatment applications, membrane fouling and fouling of membrane elements will inevitably occur, which will affect the filtration efficiency and service life of elements. Therefore, reducing membrane fouling and anti-fouling of membrane elements, improving the filtration efficiency of membrane elements, prolonging their service life, improving the uniformity of water flow in elements, and especially the optimized design of filter elements are increasingly concerned.

The filter elements in the existing external pressure column type hollow fiber membrane elements generally have two structural forms: one is double-ended casting, that is, it has a resin fixed layer at the water outlet and a resin fixed layer at the water inlet, and at least one end is open; One is pouring through a U-shaped single-end opening to form a resin fixing layer at the water outlet. Both structures suffer from the following implementation flaws:

First, the two ends of the double-ended pouring filter element are the resin fixed layer at the water inlet and the resin fixed layer at the water outlet, and the hollow fiber membrane is fixed between them. Therefore, it is very easy to damage the root of the membrane during use, which greatly reduces the damage of the membrane. Component life.

Second, for the external pressure membrane elements fixed at both ends, the water flow path between the fibers is relatively narrow, which can easily form dead angles and easily lead to clogging. The clogged membrane elements will not be recoverable, which will directly affect their service life.

Third, for the U-shaped single-end cast filter element, the inner water channel of the membrane wire is bent, and when it is affected by the shearing action of the water flow and the concentration of the impact stress of the water flow, the service life of the membrane element will be significantly reduced.

Fourth, regardless of whether it is a filter element cast at both ends or single-ended, when pouring resin, due to the climbing rod effect of the polymer, the resin will climb up along the outer wall of the fiber filament. The height of the resin fixed layer will be lower than the climbing height of the resin along the outer wall of the fiber filament, which will exacerbate the embrittlement of the fiber filament root. In this way, when the fiber filament shakes during use, its root is easily broken, which not only directly affects the service life of the membrane element, but also makes it difficult to ensure the quality of the effluent.

In response to the above problems, a large number of patents or patent applications have improved the pollution resistance of the hollow fiber membrane to a certain extent by optimizing the casting method of the membrane module, or by changing the design of the module end and flow channel, and prolonging the life of the module. service life and operating cycles. For example, Chinese patent applications 200510015346.X, 200910110831.3 or ZL200520027729.4 disclose the use of secondary pouring at the root of the hollow fiber to form a protective layer to prevent damage to the fiber membrane and improve the quality of the effluent and the service life of the membrane element. However, due to the cumbersome and complicated preparation and design optimization of the membrane elements, the maintenance of the membrane elements, the pollution resistance of the membrane filaments, and the water quality of the entire membrane filtration device cannot be well considered.

Another example is the US patent application US5248424 which discloses an arched shellless and unconstrained hollow fiber membrane module arranged between water collecting substrates, so that the membrane filaments are in a floating state and can swing freely. This technology can increase the degree of freedom of the membrane filaments and improve the water treatment performance. However, in actual use, it is found that the membrane filaments in the floating state will be in the shape of a large screen, which will cause uneven force on the membrane filaments and affect the service life of the membrane modules. and water quality.

However, in the prior art, the membrane modules are mostly designed in one piece. When the membrane filaments are completely fouled or the service life is exhausted, the membrane modules must be replaced. However, the applicant found in practice that for the whole membrane module, only the filter element in the membrane module needs to be replaced. Simultaneously replacing the remaining parts increases the use cost of the reactor and also causes waste.
