Embodiment 1

[0030] Such as figure 1 As shown, a solar absorption type seawater desalination device with a heat recovery cycle includes a seawater degassing device 1 for removing non-condensable gases, a cooling system 2, a hot water system 3, a condenser 4, an evaporator 5, and a water valve 7. Sea water tank, fresh water collection tank 9, control system, connecting pipe 11, water pump 12 for installation on the connecting pipe;

[0031] The cooling system 2 includes a cooling water tank 21, a cooling tower 22, and a cooling pipeline 23. The three are connected through the connecting pipe 11 to form a circulation path, and the connecting pipe 11 is provided with a water pump 12 and a water valve 7. The cooling pipeline 23 is placed on the generator 134 middle;

[0032] The hot water system 3 includes a solar collector 31, a hot water tank 32, and a heating pipe 33. The three are connected through a connecting pipe 11 to form a circulation path, and the connecting pipe 11 is provided wit...

Embodiment 2

[0047] The process of producing fresh water is as described in embodiment 1, increased the process of producing frozen water simultaneously, as figure 2 As shown, the process of preparing frozen water is as follows:

[0048] The dilute water vapor from the absorber 131 is passed into the condenser 4, and after the water vapor enters the condenser 4, fresh water is formed through condensation, and the circulating water pipe 41' in the condenser 4 is connected with the cooling system 2, and the cooling water is circulated through The water pipe 41' enters the condenser 4, and cools the fresh water to form frozen water, realizing the purpose of simultaneously producing fresh water and frozen water.

Abstract

The invention discloses a solar absorption type sea water desalination device with regenerative cycle. The device comprises a cooling water tank, a cooling tower, a cooling pipeline, a solar heat collector, a hot water tank, a heating pipeline, a sea water tank, a sea water degassing device, an evaporator and an absorption type circulation system, wherein the cooling water tank, the cooling tower and the cooling pipeline are circularly communicated with one another; the solar heat collector, the hot water tank and the heating pipeline are communicated with one another; the sea water tank, the sea water degassing device and the evaporator are communicated with one another; a spray nozzle is formed in the evaporator and is communicated with the evaporator; a water outlet pipeline is connected outside the evaporator; an absorber, a solution circulating pump, a solution heat exchanger and a generator are arranged in the absorption type circulation system and are communicated with one another; lithium bromide solution is filled in the absorber and the generator; a water passing pipeline is formed in the solution heat exchanger and is communicated with the absorber and the generator; the solution circulating pump is connected with a control system; the cooling pipeline is arranged in the absorber; the heating pipeline is arranged in the generator; a condenser is communicated with a fresh water collection tank; and the pump is arranged on the connecting pipe and is connected with the control system. Thus, fresh water yield is increased, and corrosion of sea water on equipment is reduced.

Description

Technical field: [0001] The invention relates to the technical field of seawater desalination, in particular to a solar absorption type seawater desalination device with a heat recovery cycle. Background technique: [0002] At present, with the rapid development of society and the rapid increase of population, the shortage of fresh water resources has attracted the attention of all countries in the world. The aggravation of the crisis of fresh water resources has led to the rapid development of seawater desalination technology. At present, seawater desalination methods for installed applications in the world are mainly divided into two categories: one is heat treatment process, mainly including multi-stage flash evaporation (MSF) and multi-effect evaporation (MED); the other is membrane treatment process, such as electrodialysis ( ED) and reverse osmosis (SWRO). However, these two methods are at the cost of consuming electric energy or a large amount of fuel, and seawater w...
