Ballast discharging neutralizer

Abstract

The invention relates to a ballast discharging neutralizer, which comprises a neutralization chamber, wherein the neutralization chamber is provided with a ballast inlet pipe, an air inlet pipe and a water outlet pipe; the ballast inlet pipe is communicated with one side of the neutralization chamber through a nozzle; the upper part of the neutralization chamber is communicated with the air inlet pipe; the air inlet direction of the air inlet pipe is not parallel to the water outlet direction of the nozzle; and the other side of the neutralization chamber is communicated with the water outlet pipe. Sprayed ballast is fully neutralized with air or pure oxygen in the neutralization chamber, so that the oxygen dissolving level of the ballast is restored to be similar to that of water in external environment; therefore, the ballast is ensured to be safely discharged; and the ballast discharging neutralizer is simple and compact in structure and safe and stable in use, has a good ballast neutralizing effect, the oxygen content of the discharged ballast reaches the standard of the water in the external environment, and the ecological environment is not influenced.

Description

technical field [0001] The invention relates to a ballast water discharge neutralizer. Background technique [0002] When a ship is loading and unloading cargo, the center of gravity and buoyancy of the ship are constantly changing. For the draft, balance and inclination of the ship, it is necessary to inject seawater into the ballast tank when it is lightly loaded; to overboard. This is the migration of ballast water. The microorganisms and bacteria in the foreign seawater lack natural enemies and flood wantonly, which causes the destruction of the ecological environment balance. [0003] In response to the inflow and discharge requirements of ballast water, most domestic and international methods currently control the oxygen content in ballast water to inhibit the growth of residual microorganisms and bacteria, thereby avoiding damage to the ecological balance caused by the migration of ballast water. If the oxygen content in the water is too low, it will easily caus...

[0003] In response to the inflow and discharge requirements of ballast water, most domestic and international methods currently control the oxygen content in ballast water to inhibit the growth of residual microorganisms and bacteria, thereby avoiding damage to the ecological balance caused by the migration of ballast water. If the oxygen content in the water is too low, it will easily cause a short-term decrease in the oxygen content in the local seawater when it is discharged, which will still affect the ecological environment
