The principle of cavitation jet cleaning determines that it is very suitable for cleaning operations in underwater submerged environments. Using a lower pressure water source will not cause harm to the operator or the surface being cleaned. There are no restrictions on the source of cleaning water. It can be tap water or sea water (pumps, pipelines, etc. need to be corrosion-resistant), and the materials are easy to obtain. There is no need to add any chemical reagents, and there is no toxic emissions during the operation. It is an environmentally friendly cleaning technology. High cleaning efficiency and convenient for automated transformation. The use of cavitation jet technology in construction can achieve high cleaning efficiency, excellent cleaning effects, safety and environmental protection construction requirements, and good economy. Compared with the traditional cleaning speed of more than ten to twenty square meters per hour, the cavitation jet cleaning disk can reach hundreds to thousands of square meters per hour, and can clean various types of dirt with different pollution levels.

Application areas

 1. Cleaning of offshore oil structures

my country's large marine structures are mainly spud-type oil production platforms, and it is expected that semi-submersible oil production platforms will gradually increase in the future. In order to ensure the safety of the platform, personnel and facilities, it needs to be effectively cleaned within a certain period. With the rapid development of the offshore oil industry, there are more and more large-scale marine structures, and cleaning tasks are increasing rapidly. Efficient and safe cavitation jet cleaning technology will become an inevitable need.

 2. Cleaning of submarine oil facilities

Offshore petroleum engineering includes a large number of seabed petroleum facilities such as underwater oil production systems. It is difficult to clean them reasonably and effectively in a complex marine environment. Carrying cleaning equipment by divers or ROVs to carry out cleaning operations is currently the only effective method. The development of modular and automated cavitation jet cleaning equipment can effectively solve the cleaning problems of underwater facilities.

3. Ship cleaning

When FPSO, ships, etc. operate in the marine environment for a long time, a fairly thick layer of marine life adhesion and dirt will be formed on the surface of the hull below the waterline. The surface of the ship's outer shell will inevitably produce large-scale rust when it runs all year round. On this basis, the attachment of algae, shells and other marine organisms will form a tight and hard dirt layer. If it is not effectively cleaned for a long time, it can form a layer as thick as 200mm. The adhesion layer of marine organisms and the fouling layer seriously affect the sailing speed of the ship, increase the fuel consumption cost, and shorten the service life of the ship. In the ship cleaning industry, cavitation jet cleaning technology undoubtedly has broad development space.

4. Coastal engineering cleaning

In common coastal projects, long-term accumulation of marine biofouling and silt directly affects the normal operation of ports, waterways, etc.; long-term erosion of marine life also has serious adverse effects on bridges, tide-proof lifts, etc., directly affecting the solidity and stability of these facilities. service life, etc. Therefore, cleaning coastal projects is of great significance, and cavitation jet cleaning technology also has broad application space.
