Description

Technical Field

[0001] This invention belongs to the technical field of ultrasonic algae removal equipment, and specifically relates to an ultrasonic algae removal device. Background Technology

[0002] Eutrophication refers to the phenomenon where large amounts of nutrients flowing into slow-moving water bodies such as rivers, lakes, and bays cause rapid proliferation of algae and other plankton, leading to decreased dissolved oxygen levels, water quality deterioration, and mass mortality of fish and other organisms. Eutrophication, with its massive algal blooms, poses a serious threat to the ecological environment and human health, becoming a global environmental problem. Furthermore, the presence of cyanobacteria makes it impossible for fish and other economic crops to survive in these water bodies, hindering irrigation and depriving livestock of their essential water resources. This severely restricts the development of agriculture, forestry, animal husbandry, and fisheries. Tourism industries reliant on natural resources are gradually disappearing due to water pollution, resulting in significant socio-economic losses. Therefore, the remediation of eutrophic water bodies and algal blooms remains extremely urgent.

[0003] Traditional methods for controlling cyanobacteria include physical, chemical, and biological methods. Each method has its drawbacks, failing to fully meet requirements in terms of safety, economy, and algae removal efficiency. Physical methods, primarily including manual removal, flocculation and sedimentation, and flotation, generally offer good results but are costly. Chemical methods often employ chemical agents such as copper sulfate and potassium permanganate, as well as ozone oxidation, providing rapid results but easily causing secondary pollution and struggling to completely remove algae. Biological methods, including microbial treatment, aquatic plant algae suppression, and algae-eating biological control, offer advantages such as being pollution-free, low-cost, and having significant treatment effects. However, the number of natural enemies of algae currently available is limited, and various pathological fungi or bacteriophages have narrow applicability and high specificity, making them ineffective against the complex and diverse algae in water bodies. Therefore, it is necessary to design a completely new system to optimize the shortcomings of traditional cyanobacteria control methods. Summary of the Invention

[0004] In view of this, the ultrasonic algae removal system based on frequency mixing technology provides a solution to the above-mentioned shortcomings of traditional blue-green algae control methods.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] An ultrasonic algae removal system based on frequency mixing technology includes a first ultrasonic action chamber unit, a physical separation chamber unit, a second ultrasonic action chamber unit, and a chemical sedimentation chamber unit; wherein the first ultrasonic action chamber unit, the physical separation chamber unit, and the second ultrasonic action chamber unit have similar structures and the same overall size; the four processing units are connected in sequence through an algae conveying pipe; the radius of the algae conveying pipe is the same as the radius of the algae inlet and the algae outlet, and it is tightly connected to the algae inlet and the algae outlet through a connector.

[0007] Furthermore, the inner cavity of the first ultrasonic action chamber unit is a cylinder with a height of 200cm and a radius of 60cm; the entire cavity is placed horizontally, and the thickness of the cavity wall is 2cm; the algae inlet and algae outlet are 50cm long and 2cm thick, located at the upper left and lower right of the cavity respectively, and the entire cavity is made of titanium alloy.

[0008] Furthermore, the two ultrasonic probes of the cavity are located at the center of the left and right ends of the cavity, respectively; the ultrasonic transducer is 7cm*7cm in size, with a maximum ultrasonic output power of 200W, an ultrasonic duty cycle of 50%, and a frequency of 1Hz; it is surrounded by a water cooling device.

[0009] Furthermore, the physical separation chamber unit is a cylinder with an inner diameter of 200cm and a radius of 60cm; the chamber is placed horizontally as a whole, and the thickness of the chamber wall is 2cm; the algae inlet and algae outlet are 50cm long and 2cm thick, and are located at the lower left and upper right of the chamber, respectively; the entire chamber is made of titanium alloy.

[0010] Furthermore, the cavity is equipped with a primary baffle, a secondary baffle, a tertiary baffle, and a quaternary baffle, with heights of 40cm, 60cm, 80cm, and 100cm respectively. The primary baffle, secondary baffle, tertiary baffle, and quaternary baffle are respectively 40cm, 80cm, 120cm, and 160cm away from the algae inlet end, and have a thickness of 2cm.

[0011] Furthermore, the structure of the second ultrasonic cavity unit is completely identical to that of the first ultrasonic cavity unit;

[0012] Furthermore, the inner cavity of the chemical separation chamber unit is a square pool with a length of 1500cm, a width of 600cm, and a height of 200cm, and the wall thickness of the separation chamber is 3cm.

[0013] Furthermore, the separation tank is open-topped, with the algae inlet located in the center of the side of the chamber and the algae outlet located directly below the side of the chamber.

[0014] Furthermore, the dimensions of the algae inlet of the chemical separation chamber are 100cm in length and 2cm in thickness, and the dimensions of the water outlet are 100cm in length and 2cm in thickness.

[0015] Compared with existing traditional technologies, the novel ultrasonic algae removal system described in this invention has the following advantages:

[0016] Compared to traditional physical algae removal technologies, ultrasonic algae removal systems are more efficient and have lower labor and material costs. Furthermore, while traditional physical algae removal technologies can only be used to remove algae during an algae bloom, ultrasonic algae removal systems can be used before an algae bloom occurs, eliminating algae activity and preventing it from blooming. This makes them more environmentally friendly and significantly reduces the cost of algae removal.

[0017] Compared to traditional biological algae removal technology, ultrasonic algae removal systems are not only more efficient, but can also handle more types of cyanobacteria, take less time, save time and investment costs, and achieve better results. Attached Figure Description
