Physical-means-based ballast water treatment equipment

Abstract

The invention relates to the technical field of ship ballast water treatment equipment, in particular to physical-means-based ballast water treatment equipment, which comprises a backwash filter and an ultraviolet and ultrasonic wave combined treater. Ballast water is pumped into a water inlet of the backwash filter by a ballast pump, is treated, and enters the combined treater for treatment; andthe combined treater comprises a shell with an annular channel, ultraviolet lamps annularly arranged in the annular channel, and an ultrasonic transducer positioned in the center of the annular channel. The combined treater consists of the high-power ultraviolet lamps arranged annularly and the ultrasonic transducer positioned in the center, the ballast water which is filtered and supplied with oxygen enters the combined treater along the tangential direction of the shell of the treater, spirally flows in the treater, and fully contacts the treatment field consisting of the ultraviolet lamps and the ultrasonic waves to meet the specified treatment requirement. An automatic detection and control system can automatically adjust the output energy of the ultraviolet lamps and the ultrasonic waves according to difference of water quality so as to achieve energy-saving optimal configuration.

Description

Technical field: [0001] The invention relates to the technical field of ship ballast water treatment equipment, in particular to ballast water treatment equipment based on physical means. Background technique: [0002] The hydraulic design of the ship requires that it must have a certain load to maintain stability. Therefore, an "empty" ship cannot really be empty at sea. If the ship has no cargo to transport, some alternatives must be found to maintain the ship's load. These substitutes are ballast. In early ancient ships, some heavy and low-priced items such as rocks and sand were often used as ballast. At the beginning of the 20th century, people began to load water containers on ships, and adjust the left and right balance and draft of the ship at will through water intake and drainage, so as to achieve the purpose of balancing the ship and sailing safely. Convenient and fast, it naturally replaced other solid ballast materials and became ballast water, which has been ...

Problems solved by technology

If active substances are added (produced) (such as advanced oxidation, electrolytic seawater, external oxidants, fungicides, etc.), the G9 certification route needs to be implemented. After this certification route reaches a standard, environmental toxicity assessment needs to be carried out. Completed abroad, and certified and issued by the IMO organization, the certification period is long and the cost is high
