Description

Technical Field

[0001] This utility model relates to the technical field of seawater distillation and desalination devices, and in particular to a waste heat seawater distillation and desalination device for ocean-going oil tankers. Background Technology

[0002] As a crucial carrier of cargo in international trade, ocean-going oil tankers typically require long voyages at sea. During this time, numerous activities on board generate a continuous and substantial demand for fresh water. The daily lives of the crew, including drinking, washing, and cooking, all depend on a fresh water supply. Similarly, various equipment on board, such as engine cooling systems and the operation of precision instruments, also require fresh water to ensure their proper functioning. However, ocean-going oil tankers are far from land during their voyages, making it difficult to obtain sufficient fresh water replenishment at any time. This makes fresh water a precious and scarce resource on ocean-going oil tankers, which typically employ water makers to desalinate seawater.

[0003] The propulsion systems of ocean-going oil tankers generate a significant amount of waste heat during operation. In particular, the outer shell of the water maker accumulates considerable heat due to continuous energy conversion and heat transfer. Currently, most of this waste heat is directly released into the environment, resulting in substantial energy waste. Furthermore, the large-scale release of waste heat not only increases the ship's thermal load but may also cause thermal pollution to the marine environment. Therefore, a waste heat seawater distillation and desalination device for ocean-going oil tankers is proposed. Utility Model Content

Both the coarse and fine filters are installed using a plug-in method; simply pull the handle on the surface to remove them from the filter box. The structure is simple and easy to operate, facilitating regular cleaning and maintenance by staff. This prevents impurities from entering the equipment and damaging its precision instruments, as well as causing pipe blockages. Attached Figure Description
