Description

Comprehensive power generation and seawater desalination system
Technical Field
The invention belongs to a comprehensive power generation and seawater desalination system.
Background
The existing ocean current power generation system and the solar power generation system are independent, and energy complementation cannot be realized due to respective limitations. Meanwhile, in the existing ocean current power generation system taking seawater as a medium, when the seawater is pumped to land, the seawater is not desalinated, and the energy utilization is not maximized.
Disclosure of Invention
The invention aims to solve the technical problem that seawater desalination can be completed while power generation is realized by comprehensively utilizing an ocean current module power generation system and a solar power generation system. Thereby reducing the investment recovery period of the whole machine.
The technical scheme adopted by the invention for solving the technical problems is as follows:
an integrated power generation and seawater desalination system comprising: the system comprises an ocean current energy collecting system (1) positioned in seawater, a solar energy collecting system (2) positioned on the sea surface, a thermal energy generating system (3), a seawater desalination system (4) and an ocean current energy generating system (5) positioned on land, wherein the systems are connected together through pipelines; wherein the ocean current energy collecting system (1) comprises: the system comprises a foundation pile (101), a backwashing filter (102), a seawater pump (103) and a water turbine (104), wherein the foundation pile (101) is fixed on the seabed, the water turbine (104) is installed on the foundation pile (101) and can rotate freely, an output shaft of the water turbine (104) is connected with a driving shaft of the seawater pump (103), an inlet of the seawater pump (103) is connected with the backwashing filter (102), and an outlet of the seawater pump (103) is connected with an energy conveying pipe on the seabed;
when ocean current flows, the water turbine (104) converts the kinetic energy of the seawater into rotary mechanical energy to act on the seawater pump (103), the seawater pump (103) converts the rotary mechanical energy into high-pressure potential energy to be conveyed to an energy conveying pipe on the sea bottom in the form of high-pressure seawater, and meanwhile, the other part of high-pressure seawater is conveyed to the sea surface through a pipeline and is supplied to the solar seawater control valve (201);
the backwashing filter (102) is used for filtering larger impurities in the seawater; in addition, when the backwashing filter (102) is blocked by impurities, self-cleaning can be carried out by utilizing self high-pressure seawater.
Preferably, the solar energy collection system (2) comprises: the system comprises a solar seawater control valve (201) and a solar heat absorption plate (202), wherein the solar seawater control valve (201) is arranged on a pipeline connected with the solar heat absorption plate (202), and the solar heat absorption plate (202) is arranged at a position 1-3 meters away from the high-tide sea surface;
the solar heat absorbing plate (202) is used for absorbing solar energy, converting the solar energy into heat and heating seawater flowing through the solar heat absorbing plate. The solar seawater control valve (201) mainly controls the pressure and flow of seawater flowing through the interior of the solar absorber plate (202).
Preferably, the thermal power generation system (3) comprises: the system comprises an evaporator (301), a working medium pump (302), a medium turbine (303), a generator (304), a condenser (305) and a drain pipe (306);
when the high-pressure and high-temperature seawater heated by the solar heat absorption plate (202) is conveyed to land through a pipeline and is subjected to heat energy transfer with a medium in the evaporator (301), the seawater subjected to heat energy exchange flows back to the sea;
the heat energy circulates through the medium, and after the medium carries the heat energy to the medium turbine (303), the heat energy passes through the medium turbine (303) and is converted into electric energy by the generator (304);
the medium needs to be cooled by a condenser (305) and pressurized by a working medium pump (302) for recycling.
Preferably, the cooling water of the condenser (305) is derived from the waste water of the ocean current energy power generation system (5), and the cooling water flows back to the sea after heat exchange of the condenser (305);
the medium is compressed by a working medium pump (302) after being cooled so as to achieve the purpose of recycling.
The power of the working medium pump (302) comes from high-concentration low-pressure wastewater in the seawater desalination system (4) and is obtained after conversion by a seawater motor (401).
Preferably, the seawater desalination system (4) comprises a seawater motor (401) and a reverse osmosis membrane (402); high-pressure seawater obtained through pressure regulation and flow distribution of the power generation and desalination control system (503) enters a reverse osmosis membrane (402), and fresh water is obtained after the high-pressure seawater is desalinated by the reverse osmosis membrane (402);
the waste water which is not desalted and passes through the reverse osmosis membrane (402) is converted by the seawater motor (401) to provide energy for the working medium pump (302).
Preferably, the ocean current energy power generation system (5) comprises: the power generation system comprises a power generator (501), a seawater motor (502) and a power generation and desalination control system (503), wherein high-pressure seawater output by a seawater pump (103) is transmitted to land through a submarine energy transmission pipe, flows into the seawater motor (502) after being subjected to pressure regulation and flow distribution of the power generation and desalination control system (503), and is converted into kinetic energy by the seawater motor (502) and then transmitted to the power generator (501) to complete power generation. The seawater passed through the seawater motor 502 is not pressurized, but is supplied as cooling water to the condenser 305.
Preferably, the backflushing filter (102) includes: a differential pressure valve (10301), a spray head fixing frame (10302), a rotary spray head (10303) and a filter screen (10304);
when the filter screen (10304) is blocked and the seawater pump (103) works normally, the internal pressure of the filter screen (10304) is reduced, and when the type of pressure reduction is transmitted to the rod cavity of the piston of the differential pressure valve (10301), because the rodless cavity of the differential pressure valve (10301) is not changed, the piston of the differential pressure valve (10301) is pushed to move forwards by the outside atmosphere and the water pressure together until the hydraulic control one-way valve is opened, high-pressure seawater flows into the spray head fixing frame (10302), and then flows to the rotary spray head (10303).
Preferably, the radial direction of the rotating nozzle (10303) is provided with a plurality of small holes, when high-pressure seawater enters the small holes, a jet flow is rapidly formed, and therefore, the blocked filter holes of the filter screen (10304) are cleaned.
Preferably, the outermost outlet end of the nozzle 10303 is designed to be perpendicular to the radial direction of the nozzle, so that the nozzle 10303 can rotate in the early stage of the high pressure fluid flow, thereby effectively cleaning the positions of the screen 10304.
After the scheme is adopted, the invention has the following effects:
1. the energy of ocean current and the sun can be fully utilized;

Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
As shown in fig. 1 and 2, a power generation and seawater desalination system, which comprehensively utilizes solar energy and ocean current energy, mainly comprises two parts of sea and land and five subsystems thereof.
The ocean current energy collection system (1) is located in seawater, the solar energy collection system (2) is located on the sea surface, and the thermal energy power generation system (3), the seawater desalination system (4) and the ocean current energy power generation system (5) are all installed on the land.
As shown in fig. 1, the ocean current energy collecting system (1) is composed of a foundation pile (101), a backwashing filter (102), a seawater pump (103), a water turbine (104) and pipelines thereof, wherein the foundation pile (101) is fixed on the seabed, the water turbine (104) is arranged on the foundation pile (101) and can rotate freely, an output shaft of the water turbine (104) is connected with a driving shaft of the seawater pump (103), an inlet of the seawater pump (103) is connected with the backwashing filter (102), and an outlet of the seawater pump (103) is connected with an energy conveying pipe on the seabed. The hydraulic turbine (104) is used for absorbing energy of ocean current. When ocean current flows, the water turbine (104) converts the kinetic energy of the seawater into rotary mechanical energy to act on the seawater pump (103), the seawater pump (103) converts the rotary mechanical energy into high-pressure potential energy to be conveyed to an energy conveying pipe on the sea bottom in the form of high-pressure seawater, and meanwhile, another part of the high-pressure seawater is conveyed to the sea surface through a pipeline and is supplied to the solar seawater control valve (201). The function of the back-flushing filter (102) is to filter large impurities in the seawater. Meanwhile, when the backwashing filter (102) is blocked by sundries, the self-cleaning can be carried out by utilizing the high-pressure seawater.
The solar energy collecting system (2) mainly comprises a solar seawater control valve (201), a solar heat absorbing plate (202) and pipelines thereof. The solar seawater control valve (201) is arranged on the seabed energy delivery pipe and the solar heat absorption plate (202), and the solar heat absorption plate (202) is arranged at a position 1-3 meters away from the high sea surface. The solar heat absorbing plate (202) is used for absorbing solar energy, converting the solar energy into heat and heating seawater flowing through the solar heat absorbing plate. The solar seawater control valve (201) mainly controls the pressure and flow of seawater flowing through the interior of the solar absorber plate (202).
The heat energy power generation system (3) mainly comprises an evaporator (301), a working medium pump (302), a medium turbine (303), a power generator (304), a condenser (305), a water drain pipe (306) and pipelines thereof. When the high-pressure and high-temperature seawater heated by the solar heat absorbing plate (202) is conveyed to land through a pipeline and is subjected to heat energy transfer with the medium in the evaporator (301), the seawater subjected to heat energy exchange flows back to the sea. The heat energy circulates through the medium, and after the medium carries the heat energy to the medium turbine (303), the medium turbine (303) and the generator (304) are converted into electric energy. The medium needs to be cooled by a condenser (305) and pressurized by a working medium pump (302) for recycling. The cooling water of the condenser (305) is derived from the waste water of the ocean current energy power generation system (5), and the cooling water flows back to the sea after heat exchange of the condenser (305). After being cooled, the medium needs to be compressed by a working medium pump (302) so as to achieve the purpose of recycling. The power of the working medium pump (302) comes from high-concentration low-pressure wastewater in the seawater desalination system (4) and is obtained after conversion by a seawater motor (401).
The seawater desalination system (4) mainly comprises a seawater motor (401), a reverse osmosis membrane (402) and pipelines thereof. High-pressure seawater obtained after pressure regulation and flow distribution of the power generation and desalination control system (503) enters the reverse osmosis membrane (402), and fresh water is obtained after the high-pressure seawater is desalinated by the reverse osmosis membrane (402). The waste water which is not desalted and passes through the reverse osmosis membrane (402) is converted by the seawater motor (401) to provide energy for the working medium pump (302).
The ocean current energy power generation system (5) mainly comprises a generator (501), a seawater motor (502), a power generation and desalination control system (503) and pipelines thereof. High-pressure seawater output by the seawater pump (103) is conveyed to land through a submarine energy conveying pipe, flows into the seawater motor (502) after being subjected to pressure regulation and flow distribution of the power generation and desalination control system (503), is converted into kinetic energy through the seawater motor (502), and is conveyed to the power generator (501) to complete power generation. The seawater passed through the seawater motor 502 is not pressurized, but is supplied as cooling water to the condenser 305.
As shown in fig. 2, the backwashing filter 102 is composed of a differential pressure valve (10301), a nozzle fixing frame (10302), a rotary nozzle (10303), and a filter screen (10304). When the filter screen (10304) is blocked and the seawater pump (103) works normally, the internal pressure of the filter screen (10304) is reduced, when the type of pressure reduction is transmitted to the rod cavity of the piston of the differential pressure valve (10301), because the rodless cavity of the differential pressure valve (10301) is not changed, the piston of the differential pressure valve (10301) is pushed to move forwards by the outside atmosphere and the water pressure together at the moment until the hydraulic control one-way valve is opened, high-pressure seawater flows into the nozzle fixing frame (10302) and flows to the rotary nozzle (10303), a plurality of small holes are formed in the radial direction of the rotary nozzle (10303), and when the high-pressure seawater enters the small holes, jet flow is formed rapidly, so that the blocked filter holes of the filter screen (10304) are cleaned. The outmost outlet end of the rotary spray nozzle (10303) is designed to be perpendicular to the radial direction of the spray nozzle, so that the rotary spray nozzle (10303) can rotate in the early period of high-pressure fluid flowing, and all positions of the filter screen (10304) can be effectively cleaned.
The ocean current power generation system and the solar power generation system are mutually associated and fused, so that the power generation efficiency is greatly improved, and the energy of the ocean current power generation system and the solar power generation system is fully utilized. Meanwhile, the reverse osmosis membrane is utilized to desalt the sea water, so that the effect of one system with multiple purposes is achieved.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
