Marine energy supply system with coupling of seawater desalination function and refrigeration function

Abstract

The invention discloses a marine energy supply system with coupling of the seawater desalination function and the refrigeration function, and relates to the fields of seawater desalination, energy conservation and emission reduction. A seawater desalination supply assembly of the system includes a seawater pretreatment device, a condensation heat recovery device and a reverse osmosis device; a thermal method seawater desalination supply assembly includes a piston-typed compressor, a capillary desalination evaporator, and a reused seawater pretreatment device and condensation heat recovery device; and a refrigeration cycle assembly includes a refrigerator, and a reused piston-typed compressor, throttle valve and capillary desalination evaporator. The system provided by the invention can reuse and couple the reverse osmosis water making function, the thermal method water making function and the refrigeration function, can utilize the brine pressure energy obtained in the reverse osmosiswater making process to drive refrigeration cycle, and can also perform heat exchange on feed seawater of reverse osmosis and a steam obtained in the thermal method water making process, preheats thefeed seawater, realizes the secondary concentration of reverse osmosis desalting water in a thermal method, wherein the entire process does not require additional electric power input, and is very suitable for promotion.

Description

technical field [0001] The invention relates to the field of seawater desalination and energy saving and emission reduction, in particular to a coupled marine energy supply system with seawater desalination function and refrigeration function. Background technique [0002] Like energy, water is one of the basic needs of human production and life. Each person must ensure at least 25 liters of domestic water per day (5 liters of drinking water + 20 liters of washing water), and in hot areas, the demand is even greater , the minimum domestic water consumption is 10 liters / day. As an independent individual, the ship sails far away from the land. The crew and equipment need to consume a lot of fresh water. For a sea ship with 100 people, at least 3 tons of domestic water is needed every day, and the water used for equipment (the water required for the work of ship equipment, such as boiler replenishment water) etc.) and more; for large steam-powered ships, the supplementary boil...

Problems solved by technology

At present, commercial air conditioners are generally used to meet the cooling capacity. Although the function does meet the need to solve the problem, the essence of the air conditioner is to absorb the heat in the room and discharge it to the external environment at high temperature, except that the air conditioner itself needs to consume a large amount of electricity. , its huge heat loss is often wasted
