The invention discloses a kind of sea water desaltination waterworks, can reduce the cost that desalinizes seawater.
Referring to Fig. 1, Fig. 1 is the structural representation of a kind of sea water desaltination waterworks disclosed by the invention.
This waterworks comprises generating electricity by natural energy device 1, hydrogen generator 2, hydrogen storer 3, hydrogen fuel cell 4, solar heat switch 5 and vacuum distillation plant 6.
Wherein, generating electricity by natural energy device 1 can utilize the one or more generation electric energy in wind energy, sun power and the water flow dynamic energy.The electric energy output end of generating electricity by natural energy device 1 is connected with power supply system during vacuum distillation plant is connected with the power supply system of solar heat switch 5 respectively, can be directly provides electric energy for solar heat switch 5 and vacuum distillation plant 6.Simultaneously, the electric energy output end of generating electricity by natural energy device 1 further is connected with hydrogen generator 2, when generating electricity by natural energy device 1 produces unnecessary electric energy, and can also be with unnecessary delivery of electrical energy to hydrogen generator 2, water in the electrolysis hydrogen gas generator 2 or fuel fluid produce hydrogen and oxygen.
In the implementation process, what generating electricity by natural energy device 1 can be in wind-driven generator group, solar electrical energy generation unit and the water flow dynamic energy generating set is one or more.Concrete, can select according to cost and the environment of living in of sea water desaltination waterworks.For example: if the sea water desaltination waterworks is arranged at the seashore, then can select wind power generation unit and solar electrical energy generation unit to form generating electricity by natural energy device 1, if the sea water desaltination waterworks is arranged on the sea, then can select simultaneously the wind power generation unit, solar electrical energy generation unit and water flow dynamic energy generating set form generating electricity by natural energy device 1, certainly, if the wind-force of sea water desaltination waterworks environment of living in is larger, the wind power generation unit only is set guarantees system power supply, the generating set of other types then can no longer be set, and the application does not limit it.
The hydrogen output terminal of hydrogen generator 2 is connected with the inlet mouth of hydrogen storer 3, the air outlet of hydrogen storer 3 is connected with hydrogen fuel cell 4, and the electric energy output end of hydrogen fuel cell 4 is connected with the power supply system that solar heat switch 5 is connected with vacuum distillation plant simultaneously.The electric energy that hydrogen generator 2 utilizes generating electricity by natural energy device 1 to produce is made hydrogen, and the hydrogen of making is transferred to hydrogen storer 3 stores.When the sea water desaltination waterworks is in windless condition, or be in night, or when being in the less state of water flow dynamic energy, generating electricity by natural energy device 1 possibly can't satisfy the power requirement of power unit in the sea water desaltination waterworks.At this moment, hydrogen fuel cell 4 can obtain hydrogen from hydrogen storer 3, and utilizes hydrogen gas generation, is the power supply of the power unit in the sea water desaltination waterworks, and the power supply system that is in solar heat switch 5 and the vacuum distillation plant 6 provides electric energy.
Hydrogen generator 2 can produce high-purity water in reaction process, this high-purity water is through the water outlet output of hydrogen generator 2, and this high-purity water can be stored in the water tank of peripheral hardware.
After by pump or other pumping equipments seawater being sent into the inside of solar heat switch 5,5 pairs of seawater of solar heat switch are heated, solar heat switch 5 can be heated seawater usually to 65 degrees centigrade to 75 degrees centigrade, and the water outlet by himself exports the seawater after heating to vacuum distillation plant 6 afterwards.
The water-in of vacuum distillation plant 6 is connected with the water outlet of solar heat switch 5, seawater after solar heat switch 5 is heated enters after the vacuum distillation plant 6, water in the seawater can evaporate formation water vapour rapidly in moment, water vapour forms distilled water through condensation, by the water outlet of vacuum distillation plant 6 distilled water is exported afterwards, this distilled water can be stored in the water tank of peripheral hardware.
Because the water that hydrogen generator 2 generates in reaction process is high-purity water, can directly drink, and the distilled water of vacuum distillation plant 6 outputs only is the domestic water that can be used for cleaning, therefore, the high-purity water of hydrogen generator 2 outputs and the distilled water of vacuum distillation plant 6 outputs can be stored in respectively in the different water tanks in the enforcement.
In the sea water desaltination waterworks disclosed by the invention, generating electricity by natural energy device 1 utilizes natural energy to produce electric energy, this electric energy can directly be the power unit power supply in the system, also can be used for producing hydrogen, when generating electricity by natural energy device 1 can't satisfy the need for electricity of system, be system power supply by hydrogen fuel cell 4, therefore, the employed electric energy of power unit all derives from natural energy in the sea water desaltination waterworks disclosed by the invention, thereby reduced energy consumption, and then reduced the production cost of fresh water, in addition, the seawater that enters vacuum distillation plant 6 is through heating by heat exchanger 5 very much, and can heating of 5 pairs of seawater of heat exchanger be to adopt sun power to realize very much, do not consume the energy, further reduced the production cost of fresh water.
In the enforcement, the vacuum tower in the vacuum distillation plant 6 can adopt multi-effect flashing steam multiple-effect backheat tower.The heat and mass transfer enhancement measure that multi-effect flashing steam multiple-effect backheat tower has used self-excitation to drench the multinomial advanced persons such as horizontal tube falling film evaporation, multi-effect flashing steam and multiple-effect backheat, enforcing condensation, reinforcement convection current, allow the condensation latent heat of steam obtain repeatedly recycling, make equipment heat up rapider, produce that water is faster, producing water ratio is higher.And remaining high density sea salt water can be used as the raw material of chlor-alkali manufacturing in the vacuum distillation plant 6.
