Description

Technical Field

[0001] This utility model belongs to the field of membrane separation technology, specifically a protective device for membrane modules used in membrane separation devices. Background Technology

[0002] Membrane separation technology is a technique that utilizes the selective permeability of semi-permeable membranes to achieve the separation, concentration, and purification of substances through physical or chemical processes. Its basic principle is to apply a pressure or concentration difference across the membrane, causing solutes, solvents, or gas molecules in a solution to separate due to the membrane's selective permeability. As a highly efficient separation method, membrane separation technology has been widely used in water treatment, pharmaceuticals, food, and chemical industries.

[0003] As the core component of a membrane separation system, the performance of the membrane module directly affects the separation efficiency and operating cost of the entire system. Membrane modules face various risks of damage during operation, making membrane module protection technology particularly important. Severe membrane fouling is one of the major challenges facing membrane separation technology. Membrane fouling is caused by organic matter adsorption, inorganic salt scaling, and microbial growth, which can reduce flux by 30%-50%. The cleaning frequency directly affects operating costs. Traditional membrane module protection devices mainly rely on physical interception and periodic cleaning, but their effectiveness in controlling membrane fouling under complex water quality conditions is limited. Therefore, this application proposes a protection device for membrane modules in membrane separation devices. Utility Model Content

The membrane module body 2 is connected to the buffer support mechanism 1. An ultrasonic generator 3 is disposed on one side of the buffer support mechanism 1, and a controller 4 is fixedly disposed on the other side of the buffer support mechanism 1. An ultrasonic transducer 5 is fixedly disposed at the middle position of the bottom end of the membrane module body 2, and the ultrasonic transducer 5 is connected to the ultrasonic generator 3 through a wire 6. The buffer support mechanism 1 consists of an L-shaped support leg 1 7, an L-shaped support leg 2 8, a support ring 9, and several strong... The support spring 10 and the connecting ring 11 are composed of a support ring 9 welded between L-shaped support leg 1 7 and L-shaped support leg 2 8. The strong support spring 10 is fixedly connected to the top of the support ring 9, and the connecting ring 11 is fixedly connected to the top of the strong support spring 10. The connecting ring 11 is sleeved on the outer surface of the membrane module body 2 and welded to the membrane module body 2. A gap is reserved between the inner surface of the support ring 9 and the outer surface of the membrane module body 2. Two mounting plates 12 are welded to the bottom of the sides of L-shaped support leg 1 7 and L-shaped support leg 2 8. Bolt mounting holes 13 are opened on the mounting plates 12.

[0022] The combined operation of the ultrasonic generator 3 and the ultrasonic transducer 5 can drive the water inside the membrane module body 2 to undergo ultrasonic vibration, thereby cleaning the membrane surface, reducing the possibility of membrane surface blockage, effectively protecting the membrane, and extending the membrane's service life. During ultrasonic vibration, the membrane module body 2 will also vibrate to a certain extent. At this time, the strong support spring 10 achieves a vibration buffering effect and improves the degree of freedom of the membrane module body 2.

[0023] A cover plate 14 is provided at the top of the membrane module body 2 to facilitate the disassembly, cleaning or replacement of the membrane.

[0024] A water inlet pipe 15 is fixedly installed at the top of one side of the membrane module body 2. A flexible connector 16 is installed at the top of the water inlet pipe 15.

Flexible connectors 16, 29, and 3 are all composed of a metal bellows 21, a flange 12, and a flange 23. Flanges 12 and 23 are welded to the top and bottom of the metal bellows 21, respectively. Rubber sealing rings 24 are installed on the top surface of flange 12 and the bottom surface of flange 23.

[0025] Flexible connector 16, flexible connector 29 and flexible connector 30 can improve the degree of freedom of water inlet pipe 15, water production pipe 17 and concentrate pipe 18. Metal corrugated pipe 21 has a certain buffering effect, avoiding the impact of traditional pipe hard connection on ultrasonic cleaning effect. Rubber sealing ring 24 can improve the sealing performance of flange 122 and flange 23 with pipe connection.

[0026] During operation, a buffer support mechanism consisting of L-shaped support leg one, L-shaped support leg two, support ring, several strong support springs, and connecting rings is used to buffer and support the membrane module body, improving the overall mobility of the membrane module body. An ultrasonic generator and ultrasonic transducer are installed to drive the membrane module body to vibrate ultrasonically, reducing concentration polarization on the membrane surface, decreasing contaminant adhesion, reducing the possibility of membrane blockage, improving the control effect on membrane fouling, and thus forming a membrane protection effect. Flexible connectors one, two, and three, consisting of a metal bellows, flange one, and flange two, are used to achieve flexible connections with pipelines, increasing the degree of freedom and avoiding rigid pipeline connections that would affect ultrasonic cleaning operations.
