Description

Technical Field

[0001] This invention relates to a water treatment apparatus, and more particularly to an end cap for an ultrafiltration membrane module. Background Technology

[0002] Traditional ultrafiltration membrane modules typically have two end caps, one with an inlet and the other with a product outlet. Both end caps are single-chamber units, which cannot meet the functional requirements of dual-end ultrafiltration modules. Furthermore, ultrafiltration modules within a system cannot be directly connected in series via end caps; this requires connecting pipes and fittings, resulting in a large footprint, numerous and complex connecting pipes and fittings, high costs, and hindering simplified system integration. Moreover, with only one product outlet per end cap, the higher the ultrafiltration module, the more uneven the product water distribution, leading to increased localized fouling and low membrane fiber utilization. Additionally, the different structures of the upper and lower end caps in traditional ultrafiltration modules make them incompatible. Summary of the Invention

[0003] To address the aforementioned problems in the prior art, the present invention provides an end cap for an ultrafiltration membrane module. The technical solution adopted is as follows: an end cap for an ultrafiltration membrane module includes a housing, a raw water chamber and a product water chamber formed by a separation plate and a product water distribution plate with a product water distribution hole within the housing, an inlet on the housing that communicates with the raw water chamber, a product water outlet on the upper part of the housing that communicates with the product water chamber, and an inlet channel that penetrates the product water distribution plate and the separation plate and communicates with the raw water chamber.

[0004] A further technical feature of this invention is: An air inlet is provided on the side wall of the water inlet chamber.

[0005] The upper edge of the water inlet channel is higher than the upper edge of the shell.

[0006] The water inlet is arranged on one side, or symmetrically on both sides, or symmetrically on all four sides; the water outlet is arranged on one side, or symmetrically on both sides, or symmetrically on all four sides.

[0007] The shell, isolation plate, water production and distribution plate, water inlet channel, water inlet and water production outlet are an integral structure.

[0008] Both the inlet and the outlet have clamp connection grooves on their outer circumferential surfaces.

[0009] The water inlet channel is a circular pipe that runs through the center of the water distribution plate and the center of the isolation plate, with its lower edge flush with the bottom surface of the isolation plate.

[0010] The water distribution plate has three rings of water distribution holes with its center as the center. Each ring of water distribution holes includes multiple water distribution holes evenly distributed along the circumference.

[0011] The beneficial effects of this invention are: Because this invention includes a housing, a raw water chamber and a product water chamber separated by a partition plate and a product water distribution plate within the housing, an inlet on the housing communicating with the raw water chamber, a product water outlet on the housing communicating with the product water chamber, and an inlet channel penetrating the product water distribution plate and the partition plate and communicating with the raw water chamber, the upper and lower end caps have identical structures and can be interchanged. Each end cap includes a raw water chamber and a product water chamber, which can meet the needs of dual-end product water ultrafiltration components. Moreover, it integrates the inlet and product water outlet onto a single end cap, allowing two ultrafiltration components in the ultrafiltration system to be connected via the inlet and product water outlet. This achieves high integration, convenient installation, and high space utilization of the ultrafiltration system, effectively reducing the number of pipe connections, lowering the risk of leakage, and simplifying system maintenance procedures. Through optimized structural design, the end caps have integrated flow channels, enabling multi-channel parallel processing and improving the overall operating efficiency of the ultrafiltration components. This design overcomes the limitations of traditional end caps in compact system layouts, meets the needs of modern water treatment equipment for simplification and modularization, and the ultrafiltration components using this type of end cap have a more uniform water production distribution in the height direction, improved membrane fiber utilization, and are less prone to localized fouling.

Detailed Implementation

[0013] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0014] like Figure 1 , Figure 2 and Figure 3As shown, an end cap for an ultrafiltration membrane module according to a specific embodiment of the present invention includes a housing 1, a raw water chamber 4 and a product water chamber 5 formed within the housing by a partition plate 2 and a product water distribution plate 3 with a product water distribution hole 10, an inlet 6 on the housing 1 communicating with the raw water chamber, a product water outlet 7 on the housing 1 communicating with the product water chamber 5, and an inlet channel 8 penetrating the product water distribution plate 3 and the partition plate 2 and communicating with the raw water chamber 4. In this embodiment, an air inlet 9 is also provided on the side wall of the raw water chamber 4 to facilitate the introduction of high-pressure gas to rinse the membrane fibers; the upper edge of the inlet channel 8 is higher than the upper edge of the housing 1. The inlet 6 and the product water outlet 7 are arranged symmetrically on both sides. Furthermore, in this embodiment, clamp connection grooves 11 are provided on the outer peripheral surfaces of the inlet 6 and the product water outlet 7, which facilitates the connection between the two ultrafiltration components in the ultrafiltration system through the inlet 6 and the product water outlet 7; the inlet channel 8 is a circular pipe that passes through the center of the product water distribution plate 3 and the center of the isolation plate 2, and its lower edge is flush with the bottom surface of the isolation plate 2; the product water distribution plate 3 has three rings of product water distribution holes 10 with its center as the center, and each ring of product water distribution holes includes multiple product water distribution holes evenly distributed along the circumference; the shell 1, the isolation plate 2, the product water distribution plate 3, the inlet channel 8, the inlet 6 and the product water outlet 7 are an integral structure.

[0015] In practical applications, the water inlet 6 can also be arranged on one side or symmetrically on all four sides; the water outlet 7 can also be arranged on one side or symmetrically on all four sides.

[0016] Figure 1 , Figure 2 , Figure 3 The illustrated embodiment describes its use as a lower end cap. When used as an upper end cap, the corresponding water inlet becomes a concentrate outlet, the water inlet channel becomes a concentrate channel, the raw water chamber becomes a concentrate chamber, and the product water chamber remains a product water chamber. When used as an upper end cap, the air inlet can be blocked with a plug.

[0017] Because this invention includes a housing 1, within which a raw water chamber 4 and a product water chamber 5 are formed by a partition plate 2 and a product water distribution plate 3, an inlet 6 on the housing 1 communicating with the raw water chamber 4, a product water inlet 7 on the housing 1 communicating with the product water chamber 5, and an inlet channel 8 penetrating the product water distribution plate 3 and the partition plate 2 and communicating with the raw water chamber 4, the upper and lower end caps have identical structures and are interchangeable. Each end cap includes a raw water chamber 4 and a product water chamber 5, which can meet the needs of dual-end product water ultrafiltration components. Moreover, it integrates the inlet 6 and the product water inlet 7 onto one end cap, so that two ultrafiltration components in the ultrafiltration system can be connected through the inlet 6 and the product water inlet 7. This achieves high integration of the ultrafiltration system, convenient installation, high space utilization, effectively reduces the number of pipeline connections, reduces the risk of leakage, and simplifies the system maintenance process. Through structural optimization design, the end cap has a flow channel integration function, realizing multi-channel parallel processing and improving the overall operating efficiency of the ultrafiltration component. This design overcomes the limitations of traditional end caps in compact system layouts, meets the needs of modern water treatment equipment for simplification and modularization, and the ultrafiltration components using this type of end cap have a more uniform water production distribution in the height direction, improved membrane fiber utilization, and are less prone to localized fouling.
