Abstract
The utility model relates to the technical field of ballast water treatment, in particular to an ultrasonic device for treating ship ballast water, which can effectively improve the ballast water treatment effect.
Description
Technical Field
The utility model relates to the technical field of ballast water treatment, in particular to an ultrasonic device for ship ballast water treatment.
Background
Generally, a large ship has more or less ten ballast tanks at the lower part and sides of the ship to maintain the balance of the ship while underway. The water in the ballast tanks of the ship (seawater, brackish water or fresh water) is called ballast water to maintain the desired balance of the ship. The ballast tanks are filled with seawater, fresh water in the river, and mixtures of both, pumped from the world's ocean and discharged again as needed. When a ship discharges cargo, it fills with ballast water. Ballast water is pumped into the ship's ballast tanks at one port, which typically includes various microorganisms and sludge, and thus, if the ballast water is discharged from the tanks in the other port water without special treatment or water treatment, the water reaching the port may be severely contaminated.
In order to meet the requirements of ballast water discharge regulations, various systems for treating ship ballast water have been proposed and used, wherein representative main treatment methods are ultraviolet rays, electrolysis or chemical techniques. Many companies have developed ballast water management systems using various methods, such as a filter device having a fine mesh (mesh size: 20 ㎛ to 550 ㎛) for a prefilter and a main sterilizing device for ultraviolet rays, electrolysis, ozone, nitrogen gas, chemical treatment, etc., but in order to meet the regulations of IMO and USCG (united states cost protection organization), almost all devices use the fine mesh filter device for prefiltering, the structure is complicated, and the filter often has a problem of top blocking, so that the ballast water management system often has a problem due to high maintenance cost, and for this purpose, an ultrasonic treatment device has been developed, the structure of which is shown in fig. 1, an ultrasonic transducer is fixed to the outer wall of a ballast water treatment housing, but in practical use, the water flow speed of the inner central region of the housing is fast, and the sterilizing effect of ultrasonic waves for microorganisms in the central region of the housing is not good.
Disclosure of Invention
In order to solve the problem of poor ballast water treatment effect of the existing ultrasonic wave, the utility model provides an ultrasonic wave device for treating ship ballast water, which can effectively improve the ballast water treatment effect.
The technical scheme is as follows: the ultrasonic device for treating the ballast water of the ship comprises a ballast water treatment shell, wherein an inlet flange and an outlet flange are respectively arranged at two ends of the ballast water treatment shell, and an ultrasonic transducer is fixed on the outer wall of the ballast water treatment shell.
The ballast water treatment device is further characterized in that the adjacent circular rings are arranged at equal intervals, the circular ring with the smallest diameter in the middle is sleeved with a fixed shaft, one end of the fixed shaft is provided with at least two support rods, clamping grooves matched with the circular rings are formed in the support rods, one end of the circular ring is clamped into the clamping grooves for fixation, and one end of the fixed shaft is connected with a fixed support inside the ballast water treatment shell;
The ballast water treatment shell comprises a polygonal cylinder body outside and a cylindrical channel inside, and reinforcing plates are welded at intervals outside the ballast water treatment shell.
After the utility model is adopted, the cylindrical perforated baffle plate assembly is added, so that the ballast water in the central area after entering the shell flows and disperses, the water in the shell can be guided to the outside through the circular ring with meshes, the flow speed of the ballast water in the whole shell can be basically kept consistent, the ultrasonic waves generated by the ultrasonic transducer can effectively influence all the ballast water, and the sterilization and disinfection effects are improved.
