Embodiment 1

[0031] Such as figure 1 , a seawater desalination device for ships, which includes a raw seawater chamber 1 and a desalinated water chamber 7, the raw seawater chamber 1 and the desalinated water chamber 7 are separated by a waterproof insulation partition 5; the top of the raw seawater chamber 1 is arranged There are raw material seawater inlet valve 12, exhaust valve 11 and vacuum gauge 13; the inside of the raw material seawater chamber 1 is provided with a connecting pipe, and the solar air heat collector 2 and auxiliary heater 8 are successively installed on the connecting pipe, and It is connected with the condensate heat pipe 4; the top of the raw seawater chamber 1 is connected with the condensate heat pipe 4 through a communication pipe, and a micro pipeline fan 3 is installed on the communication pipe; the other end of the condensate heat pipe 4 is connected with the desalinated water chamber 7 connected. By adopting the above-mentioned marine seawater desalination ...

Embodiment 2

[0037] The process of seawater desalination using any one of the marine seawater desalination devices, it comprises the following steps:

[0038] Step1: Close the concentrated seawater outlet valve 10, the desalinated seawater outlet valve 9 and the exhaust valve 11, and introduce the desalinated seawater through the raw seawater inlet valve 12, when the liquid level in the raw seawater chamber 1 reaches the range of 2 / 3~3 / 4 When, close raw seawater inlet valve 12, stop the introduction of desalinated seawater;

[0039] Step2: Connect the exhaust port of the miniature vacuum pump to the exhaust valve 11, open the exhaust valve 11, start the miniature vacuum pump to extract air to form a slight negative pressure environment inside the desalination device, and determine the initial negative pressure inside the device according to the reading of the vacuum gauge 13. After the pressure value reaches the set micro-negative pressure value, close the exhaust valve 11, stop the micro-...

Abstract

The invention relates to a marine seawater desalination device and process. The device and process realize ultra-low energy-consumption sustainable desalination seawater production of an ocean-going ship by integrating self-contained energy and heat pipe technologies, the device is simple in structure, stable and reliable, and a main energy consumption component of the device is a pipeline miniature fan; when the power consumption of the device is extremely low, the device can be driven by a solar photovoltaic electric plate or a marine wind driven generator; desalinated seawater generated bythe process can be directly drunk, desalinated water is high in quality, the production speed is high, desalinated seawater is continuously produced in an all-weather manner, and abundant wind energyand solar energy possessed by the ocean-going ship are reasonably utilized to lower the comprehensive fuel consumption of ship operation, so that the device is especially suitable for ships sailing over ultra-long distances. The device and process can be further used for seawater desalination production in coastal areas.

Description

technical field [0001] The invention relates to a marine seawater desalination device and process. The device uses clean energy including wind energy, solar energy, etc. for self-sufficient seawater desalination production. It is energy-saving and environmentally friendly, and can be applied to various ship equipment, especially for ocean-going ships. , reduce energy consumption, improve endurance and self-sufficiency, and ensure the safety of navigation. This technology belongs to the fields of navigation, energy conservation and environmental protection. Background technique [0002] Ships need to consume a lot of fresh water during their operation at sea, mainly including diesel engine cooling water, boiler feed water, domestic water for crew and passengers, etc. Seawater desalination is an effective way to ensure the continuous and stable supply and replenishment of fresh water required by ships. There are seawater desalination technologies including distillation, revers...
