Abstract

The invention discloses a seawater reverse osmosis desalination apparatus for boats. The apparatus comprises a pretreatment unit and a reverse osmosis membrane treatment unit, and the pretreatment unit comprises a self cleaning filter, a multi-medium filter and a water tank which are sequentially connected through a water pipe; and the reverse osmosis membrane treatment unit comprises a reverse osmosis membrane device, a self cleaning system and a high-pressure water pump, the motor of the high-pressure water pump is provided with a frequency converter, and the pressure and the flow of the pump can be adjusted through the frequency converter. The invention also discloses a seawater reverse osmosis desalination technology for boats. A reverse osmosis membrane is used to desalinate seawater in order to develop the seawater reverse osmosis desalination apparatus for boats, having the advantages of compact structure, high automation degree, high reliability and flexible power matching.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a marine reverse osmosis seawater desalination process and device. [0002] Background technique [0003] With the rapid growth of the global economy and the increasingly close and frequent business exchanges, the ocean shipping industry has made great progress, and the modern shipbuilding industry is also developing rapidly. Seawater desalination device is an important equipment in ocean-going ships, which provides daily fresh water for ships. For ocean-going ships, taking less fresh water when setting off can reduce operating costs and improve their endurance. [0004] Seawater desalination technologies mainly include distillation and membrane methods. Before the 1960s, ships basically used distillation desalination devices. With the commercialization of reverse osmosis seawater desalination technology, marine reverse osmosis seawater desalination devices also...
