Ship ballast water discharge device with double-rotating electrolytic organism and anti-species-migration function

Abstract

The invention discloses a ship ballast water discharge device with a double-rotating electrolytic organism and anti-species-migration function. The structure of the ship ballast water discharge devicecomprises a water-carrying cavity, an electrolytic drainage device, a ship body and a deck. The deck is fixedly arranged on the ship body, and the electrolytic drainage device is connected with the water-carrying cavity. The electrolytic drainage device penetrates through the inner wall of the water-carrying cavity. The water-carrying cavity is arranged at the bottom of the ship body, and is fixedly connected with the ship body. The ship ballast water discharge device has the advantages that the pressure of the ballast water drives the rotating shaft to rotate counterclockwise when draining the ballast water, so that the organism carried in the ballast water passes through the electrolysis of the current on the coarse power grid and the dense power grid. Therefore, the effect of killing the organisms in the original water is achieved. The ship ballast water discharge device avoids that the species in the different current or sea area that are lack of natural enemies from propagating massively in a new environment, thereby ensuring the balance of the original ecological environment.

Description

technical field [0001] The invention relates to the field of ship ballast water treatment equipment, in particular to a double-rotating electrolytic organism anti-species migration ship ballast water discharge device. Background technique [0002] In order to control the ship's heel, trim, draft, stability or stress, it is necessary to add water to the ship, which is the ship's ballast water. Since the ship's ballast water generally comes from the ship's departure port or the coastal waters it passes through, it is easy to Organisms or a wide variety of organisms in one water area are transported to another geographically isolated water area with ballast water, becoming alien invasive species, and ballast water can also transmit harmful parasites and pathogens, and may even cause local species. Extinct, the current ship ballast water treatment equipment has the following defects: [0003] When replacing the ballast water, because the original ship’s ballast water contains e...

[0002] In order to control the ship's heel, trim, draft, stability or stress, it is necessary to add water to the ship, which is the ship's ballast water. Since the ship's ballast water generally comes from the ship's departure port or the coastal waters it passes through, it is easy to Organisms or a wide variety of organisms in one water area are transported to another geographically isolated water area with ballast water, becoming alien invasive species, and ballast water can also transmit harmful parasites and pathogens, and may even cause local species. Extinct, the current ship ballast water treatment equipment has the following defects:

[0003] When replacing the ballast water, because the original ship’s ballast water contains eggs, larvae or spores of various species such as plankton, microorganisms, and bacteria, some organisms cannot adapt to the temperature, salinity, etc. Factors change and die, but the surviving organisms will be discharged into the new environment with the ship's ballast water, destroying the original ecological environment balance
