Ultrasonic Marine Growth Preventing Devices

In systems using seawater as cooling water, marine organisms entering the seawater piping system will quickly attach to and grow on the inner wall of the pipes, forming a layer of fouling accumulation. Over time, this causes severe clogging of the seawater piping system, which not only affects water flow but also greatly reduces cooling capacity, damages coolers, thereby lowering equipment operating efficiency and even endangering overall operational safety. The pillars of offshore oil drilling platforms are eroded by marine organisms, shortening their service life and affecting platform safety. Traditional marine growth prevention measures have poor effectiveness, low performance, and high failure rates, making them unsuitable for the rapidly developing marine industry. After years of research and testing by us, a new type of ultrasonic marine growth prevention device has gradually replaced traditional marine growth prevention equipment.

This device complies with current maritime registration laws and regulations, as well as all applicable international laws and pollution prevention laws. It does not use chemicals, additives, or toxic substances, relying solely on high-frequency vibration transmission. It has no impact on the human body, no corrosion to pipes and other components, and does not endanger or alter the marine ecological environment in any way.

The installation of the device is very convenient: fix the ultrasonic generator on the surface of pipe walls or platform pillars where marine organisms are prone to attachment, and connect the generator to the power controller with a cable. Therefore, there is no need to enter a maintenance factory or stop navigation—installation can be completed even during navigation.

Ultrasonic waves are emitted by sensors mounted on the pipe surface, creating a marine organism-preventive environment inside the pipes, which can effectively prevent marine biofouling and adhesion. As long as the ultrasonic generator operates continuously for 24 hours, no management or maintenance is required, enabling long-term prevention of marine organism adhesion and fouling. Its working principle is as follows: The continuous oscillation of ultrasonic waves prevents marine organisms from adhering to the inner walls of pipes and tanks. The intense ultrasonic sound field acts on marine organisms and fluids, causing a series of changes in their physical forms and chemical properties, leading to dispersion, fragmentation, loosening, detachment, and death. Thus, marine organisms cannot attach and accumulate in the cooling system.

This product is designed to prevent corrosion and marine organism adhesion in seawater piping systems, providing continuous, uninterrupted operation. It features prominent advantages including marine organism removal and prevention, corrosion protection, improved operational efficiency, sterilization and algae elimination, environmental friendliness, and energy conservation.

This equipment can be installed on ships, drilling platforms, seawater-cooled power plants, seawater desalination plants, fire pumps using seawater, and other related facilities.

1. Physical marine organism prevention method, no chemical agents required; pollution-free and noiseless, thus causing no side effects on human bodies or equipment.
2. Remarkable marine organism prevention effect: under normal circumstances, the pipeline corrosion rate can be controlled below 0.03mm/y, and the marine organism protection effect reaches over 96%.
3. Vibration between the pipe wall and water generates microflows, reducing water resistance and increasing water flow rate.
4. Long-term online operation with unattended monitoring, no shutdown required, saving substantial funds; reducing economic losses caused by equipment corrosion and shutdown, and eliminating environmental pollution arising therefrom.
5. Reduces corrosion caused by marine organisms and extends the service life of equipment.
6. The ultrasonic marine growth prevention device features small size, light weight, long service life, high maintenance-free level, and easy installation, without the need to modify or damage the structure of the equipment in use.
7. The equipment consumes very little power and has extremely low operating costs.
8. The equipment never comes into contact with seawater and requires no drilling, so installation can be carried out on ships under navigation, and seawater can flow normally in the pipeline.
9. Advanced controller technology with stable and reliable performance; core components adopt high-quality parts, with high circuit integration and full intelligence, ensuring basically no faults during long-term operation.
10. The transducer has a simple structure, advanced fixing technology, and high energy conversion efficiency; the coil is wound with high-temperature and high-pressure polyester Teflon wire, ensuring stable operation and excellent safety performance.
