Description

Evaporative Desalination Apparatus Using Hot Water, Evaporative Desalination Method and Evaporative Desalination System Using Evaporative Desalination Apparatus, Desalination Method and System therewith

The present invention relates to an evaporative desalination apparatus, and more particularly, to an evaporative desalination apparatus and an evaporative desalination method using hot water as a heat source, and an evaporative desalination system.

In general, the process of separating freshwater from seawater is divided into thermal energy, mechanical / electrical energy, and renewable energy system according to the energy source, and depending on the freshwater manufacturing method, multi-stage distillation (MSF), multi-effect evaporation method ( Multi-Effect Evaporation (MED) and Reverse Osmosis (RO) exist, and recently, a method of obtaining fresh water using membrane separation rather than thermal energy-based desalination process with high energy loss due to latent heat is being studied. have.

The multi-stage desalination system of the dual multi-effect evaporation method, as shown in FIG. 1, is designed to reuse the discharged arrangement, thereby reducing steam consumption and heating energy. However, when the desalination system is made in multiple stages according to the size of the desalination system, as the number of stages increases, there is a problem in starting efficiency and economic efficiency compared to an increase in freshwater production.

The seawater desalination process is a reverse osmosis (RO), membrane distillation (Membrane distillation, MD), forward osmosis (Forward osmosis) process, which combines the characteristics of thermal energy-based distillation and membrane separation. osmosis, FO) method.

However, the reverse osmosis process requires a high pressure greater than the osmotic pressure for separation, there is a disadvantage that requires a high energy level of electrical energy for this, because of this, forward osmosis process using the osmotic pressure as it is, not reverse osmosis process This was developed.

The forward osmosis process for seawater desalination is operated by the difference in concentration between seawater and induction solution of higher concentration than seawater, and seawater flows into draw solution, and the concentration of seawater is high and the concentration of induction solution is low.

This lower concentration of the induction solution is separated again into an induction solution and fresh water, and thus, the electroosmotic process is a membrane process, a process in which the seawater and the induction solution meet a membrane process, an induction solution and fresh water The process consists of two sub-processes, the draw solution recovery system.

As a method used for the induction solution recovery process, a multi-stage distillation method, a reverse osmosis process, a method using a distillation column, and a method using a vacuum membrane distillation (VMD) are mentioned.

Membrane distillation is common with multi-stage distillation and distillation column in that it uses thermal energy, but in terms of separation due to pressure difference in vapor pressure, there is an advantage that the temperature of the liquid does not have to be raised to the boiling point. This means that it is possible to operate at low temperatures, and that it is possible to use various heat sources such as solar, geothermal and renewable energy.

Therefore, there is a demand for the development of a desalination apparatus for seawater that can use these methods more efficiently and efficiently.

Evaporative fresh water system, characterized in that. The method of claim 16,
The multi-effector 120, the lower space includes two or more evaporation tank 122 in communication with each other,
Evaporative fresh water system, characterized in that the bottom of the two or more evaporation tanks 122, the lower barrier wall 123 protruding by a predetermined height to partition each evaporation tank 122 is mounted. The method of claim 16,
The multi-effector 120,
An injection space 124 positioned above the multi-effector 120 and having a second spray injection unit 121 disposed thereon;
An evaporation space 125 disposed separately from the injection space 124 on the upper side of the multi-effector 120; And
An upper barrier wall 126 extending downward from the inner ceiling surface of the multi-effector 120 by a predetermined length to separate the injection space 124 and the evaporation space 125 from each other; Drinking fresh water system. The method of claim 18,
Evaporative fresh water system, characterized in that a plurality of upper barrier wall 126 is mounted on the inner upper portion of the multi-effector 120 to form a plurality of injection spaces (124) and evaporation space (125). delete In the evaporative fresh water method of producing fresh water using hot water or high temperature seawater,
Hot water or hot seawater is sprayed in the first spray injector of the flash chamber 110 to evaporate under reduced pressure to generate steam, and the multi-effector 120 through the pipe 111 or the boiling tube 114. Supplying steam to the interior of the shell;
After being sprayed by the spray injection unit 112, the evaporated hot water or seawater is stored in the storage tank 113, and the received hot water or seawater is supplied to the multi-effector 120 through the seawater supply pipe 115. step;
Evaporating hot water or seawater supplied through the seawater supply pipe 115 using the steam supplied through the pipe 111 or the boiling tube 114 as a heat source in the multi-effector 120; And
Condensation step of producing fresh water by condensing the steam generated in the multi-effector 120, including,
As the internal pressure of the multi-effector 120 is reduced, the hot water or seawater supplied therein is the second spray injection unit 121, the boiling tube 127 and the evaporation tank 122 through which hot steam flows. Evaporative fresh water method characterized in that converted to steam.
