Microalgae exovesicle extraction vibrating membrane separation device

Abstract

This invention relates to a microalgae exovesicle extraction and vibration membrane separation device. It comprises a main frame with a shaking rod fixed to its bottom end, and a filter cartridge fixed to its top end. The filter cartridge contains a filter membrane assembly composed of multiple membrane sheets. A source liquid pipe is connected to the top of the filter cartridge, a permeate liquid pipe is connected to the center of the bottom of the filter cartridge, and a concentrate liquid pipe is connected to one side of the bottom of the filter cartridge. The bottom of the main frame features one or more ultra-high frequency sinusoidal vibration mechanisms. The filter membrane assembly resonates with the filter cartridge at the same frequency, generating a large sinusoidal shear force on the membrane surface, effectively preventing the accumulation of microalgae exovesicles or contaminants on the membrane surface and maintaining high permeation flux. This invention's ultra-high frequency vibration filtration mechanism can more effectively prevent the accumulation of microalgae on the membrane surface, significantly increasing the permeation flux of target components such as water molecules.

Description

Microalgae exovesicle extraction vibrating membrane separation device Technical Field

[0001] This invention belongs to the field of membrane filtration technology, and specifically relates to a microalgae exovesicle extraction vibration membrane separation device that uses an ultra-high frequency sinusoidal vibration mechanism for dynamic filtration. It is suitable for applications such as cosmetic biotechnology extraction, water resource recycling, solid-liquid separation, emulsion demulsification, molecular weight separation, and particle segmentation. Prior Technology

[0002] Note that membrane separation technology is an important means of water treatment and recycling, and is gaining increasing attention with the development of cosmetics and biotechnology. However, traditional static membrane filtration technology has the following technical drawbacks: Severe membrane fouling: In static membrane filtration, suspended solids, oils, colloids, and macromolecules in the liquid easily accumulate on the membrane surface, forming a filter cake layer, leading to a rapid decrease in permeate flux. Frequent clogging and high cleaning costs: After the membrane becomes clogged, frequent chemical cleaning or backwashing is required, consuming large amounts of cleaning agents and shortening the membrane's lifespan, resulting in high maintenance costs. Limited cross-flow filtration efficiency: Although cross-flow filtration (see Figure 4) uses conventional membrane A1 to remove some microalgal vesicles or contaminants A2 through tangential liquid flow, allowing water molecules A3 to pass through conventional membrane A1, its effectiveness in treating high-concentration liquids is limited, and it requires a large amount of energy to maintain a high flow rate. High pretreatment requirements: Traditional membrane separation systems have strict requirements on the suspended solids and oil content of the feed liquid, requiring complex pretreatment processes, increasing the system's footprint and construction costs. Emulsified fluids are difficult to handle: In highly emulsified emulsions such as cutting fluids, the emulsified oil particles are small and stable, making it difficult for traditional filtration technologies to separate them effectively, resulting in difficulties in fluid treatment. Therefore, the industry urgently needs an innovative filtration device that can effectively overcome membrane and liquid clogging problems, is suitable for handling high-concentration and complex liquids, and has a high permeation flux.

[0003] Therefore, in view of the problems existing in the above-mentioned conventional structures, how to develop a more ideal and practical innovative structure is what consumers eagerly expect, and it is also the goal and direction that relevant businesses must strive to achieve through research and development.

[0004] In view of this, the creator, based on years of experience in manufacturing, developing and designing related products, has designed and carefully evaluated the above objectives, and finally created a work that is truly practical. Summary of the Invention

[0005] The purpose of this invention is to provide a microalgae exovesicle extraction vibrating membrane separation device that overcomes the shortcomings of previous technologies. It uses an ultra-high frequency sinusoidal wave vibration mechanism for dynamic membrane filtration, fundamentally solving the pollution and clogging problems of static membranes or cross-flow filtration. Furthermore, it can be applied to fields such as concentration, water molecule filtration, solid-liquid separation, emulsion demulsification, and particle separation, with a wide range of applications.

[0006] To achieve the above objectives, this invention provides a microalgae exovesicle extraction vibrating membrane separation device, comprising: a main frame with a shaking rod fixed to its bottom end, a filter cartridge fixed to its top end, a filter membrane assembly composed of multiple membrane sheets inside the filter cartridge, a source liquid pipe connected to the top of the filter cartridge, a permeate pipe connected to the center of the bottom of the filter cartridge, and a concentrate pipe connected to one side of the bottom of the filter cartridge; and one or more ultra-high frequency sinusoidal vibration mechanisms at the bottom of the main frame, which cause the filter membrane assembly to resonate with the filter cartridge at the same frequency, generating a large sinusoidal shear force on the membrane surface, effectively preventing the accumulation of microalgae exovesicles or contaminants on the membrane surface and maintaining high permeation flux. This invention's ultra-high frequency vibration filtration mechanism can more effectively prevent the accumulation of substances on the membrane surface and significantly increase the permeation flux of target components such as water molecules.
