Description

Technical field:

[0001] The invention relates to the field of cruise ship black and gray water tank structure design, in particular to a black and gray water tank overflow system and a ship thereof. Background technology:

[0002] Some black and gray water tanks (more than 8) on cruise ships are generally concentrated in one area due to functional design requirements. According to the requirements of the specification, if the height of the vent pipe in the cabin equipped with a pump injection pipeline exceeds the design pressure of the cabin, an overflow pipeline must be installed. Due to the special structure of the cruise ship, the height of the vent pipe is relatively high, and the cost of increasing the design pressure of the cabin is higher than setting an overflow pipeline, so the solution of setting an overflow pipeline is generally adopted to meet the requirements of the specification. The existing solution generally sets an overflow pipe for each cabin separately. Because the cabins in this area are densely packed, the overflow pipe is difficult to arrange, and multiple drainage ports need to be opened on the side of the ship, so the above design structure is complicated.
