Description

Technical Field

[0001] This utility model relates to a novel low-cost flat sheet membrane module, belonging to the technical field of water treatment systems. Background Technology

[0002] Reverse osmosis (RO) technology is one of the most widely used water treatment technologies, especially in seawater desalination, industrial wastewater treatment, and domestic drinking water purification. As the core component of an RO system, the performance of the reverse osmosis membrane module directly determines the overall system's operating efficiency and economy.

[0003] However, traditional CDRO membrane modules have some significant drawbacks in design and application. For example, traditional CDRO membrane modules typically use a single membrane core design, which results in higher costs; each independent membrane core and membrane shell structure makes the entire equipment occupy a large space; when replacing and cleaning the membrane core, a large number of connectors need to be disassembled, which is complicated and time-consuming; due to low membrane material utilization and flow channel design issues, the overall water treatment efficiency of traditional membrane modules is low, requiring higher energy input to achieve the expected treatment effect, resulting in high energy consumption. Utility Model Content

[0004] Therefore, this utility model provides a novel low-cost flat sheet membrane module, which solves the problems of high cost, large space occupation, complex maintenance and high energy consumption of traditional CDRO membrane modules.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel low-cost flat sheet membrane module, comprising a membrane shell, a membrane core, quick connectors, an inlet, an outlet, and an end cap;

[0006] The membrane housing has end caps at both ends of the opening, the membrane core is placed flat inside the membrane housing, one end of the membrane housing has the water inlet between the end cap and the membrane core, and the other end of the membrane housing has the water outlet between the end cap and the membrane core.

[0007] As a preferred embodiment of a novel low-cost flat sheet membrane module, the membrane core includes a left fastener, a left guide plate, a right guide plate, an inlet end plate, a product water pipe, a concentrate end plate, and a right fastener.

[0008] The left fastener is connected to the water inlet end plate on one side, and the water inlet end plate is connected to the left guide plate on the other side. The left guide plate clamps one end of the water production pipe in the middle.

[0009] The other end of the product water pipe is clamped by the right guide plate, the other side of the right guide plate is connected to the concentrate end plate, and the other side of the concentrate end plate is connected to the right fastener.

[0010] As a preferred solution for a novel low-cost flat sheet membrane module, the quick connector includes a connector body and a product water adapter;

[0011] The water production adapter is located in the middle of the connecting body, and the end of the water production adapter is connected to the end of the water production pipe.

[0012] As a preferred solution for a novel low-cost flat-panel membrane module, the membrane core is provided with four membrane cores, and adjacent membrane cores are connected end to end by the quick connector.

[0013] As a preferred solution for a novel low-cost flat sheet membrane module, the inlet end plate and the concentrate end plate are provided with the sealing ring on the side of the product water pipe.

[0014] As a preferred embodiment of a novel low-cost flat sheet membrane module, the membrane shell has an internal partition, and the left and right guide disks have a spiral flow guiding structure.

[0015] As a preferred solution for a novel low-cost flat sheet membrane module, the inlet end plate, the concentrate end plate, and the product water pipe are all provided with the permeable holes;

[0016] The water inlet end plate is provided with two permeable holes symmetrically arranged at the top and bottom;

[0017] The permeable hole is provided on the side of the concentrated water end plate near the outlet;

[0018] The water production pipe has four permeable holes that are evenly distributed below it.

[0019] As a preferred option for novel low-cost flat-panel membrane modules, the membrane housing is provided with a protective coating.

[0020] This invention has the following advantages: it includes a long membrane housing with four flat sheet membrane cores placed inside. Each flat sheet membrane core has an independent inlet and outlet, and they operate in parallel through internal flow channels. When the system is running, water enters the inlet side of each of the four membrane cores through the four inlets. The water flows into the membrane core through a swirling motion from the inlet end plate. Permeate is collected in the permeate pipe through permeable holes, while concentrate flows into the membrane housing through the concentrate end plate and then out through the outlet. By adopting a multi-membrane core shared structure, modular design, high-strength composite material membrane housing, and low operating energy consumption, this membrane module successfully solves the problems of high cost, large space occupation, complex maintenance, and high energy consumption of traditional CDRO membrane modules. This new membrane module not only reduces material, production, and operating costs but also significantly reduces equipment size and weight, simplifies installation and maintenance, and improves equipment durability and stability. Therefore, this new low-cost flat sheet membrane module has broad application potential in seawater desalination, industrial wastewater treatment, and domestic drinking water purification, and is expected to promote the further development and popularization of reverse osmosis technology.

At the same time, the quick connector 3 facilitates installation and maintenance by connecting to other parts of the membrane assembly. The inlet end plate 23 and the concentrate end plate 26 are fitted with sealing rings 25 on one side of the product water pipe 24.

The membrane housing 1 has a protective coating on the outside to improve corrosion resistance. This invention not only reduces material, production, and operating costs but also significantly reduces equipment size and weight, simplifies installation and maintenance, and improves equipment durability and stability.
