Because components of embodiments can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting. It is to be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present application. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present application is defined by the appended claims.
The application provides a sea water desalination device, and fig. 1 shows a structure schematic diagram of the sea water desalination device according to the embodiment of the application, and as shown in fig. 1, the device mainly comprises a wind power generation device, a solar power generation panel, a wind-solar complementary charge-discharge controller, a deep circulation storage battery, an inverter, a circulation water tank, an electromagnetic induction heating device, a condenser, an evaporator and a fresh water tank.
The power generation system comprises a solar power generation plate and a wind power generation device and charges a storage battery system; the storage battery system is respectively connected with the power generation system and the sea water desalination system and provides required electric energy for the sea water desalination system; the detection system comprises: a salinity sensor, a salinity controller; the detection system is arranged in the sea water desalination system.
Specifically, the wind power generation device and the solar power generation panel charge the deep circulation storage battery under the control of the wind-solar complementary charging-discharging controller, and the electric energy stored in the deep circulation storage battery is continuously and stably supplied to the electromagnetic induction heating device, the circulating water tank water pump 2a and the circulating water pump 2b through the inverter, and other electromagnetic valves in the device.
Meanwhile, the liquid flowing in the pipeline can be divided into fresh water, seawater and desalinated seawater, so that three pipelines exist in the device.
(1) Fresh water line: when the device works, the circulating water tank water pump 2a arranged below the first water outlet of the circulating water tank starts to work, fresh water stored in the circulating water tank flows out from the first water outlet of the circulating water tank, and meanwhile, the electromagnetic induction heating device arranged below the first water outlet of the circulating water tank also starts to work, so that fresh water pumped out by the circulating water tank water pump 2a is heated when flowing through the electromagnetic induction heating device, enters the evaporator from the first water inlet of the evaporator through the stop valve 1c, flows out from the first water outlet of the evaporator, and flows back to the circulating water tank through the stop valve 1 d.
In addition, when the water level in the circulating water tank is lower than the threshold value, fresh water can be supplemented from the fresh water tank, and at the moment, the flow route of the liquid in the pipeline is as follows: fresh water flows out of the fresh water tank and flows into the circulation tank through the safety valve 3b, the safety valve 3c and the stop valve 1a provided above the circulation tank.
(2) Seawater pipeline: when the device works, the deep circulation storage battery supplies electric energy to the seawater pump 2b, the stop valve 1h at the seawater inlet is opened, seawater flows into the seawater filter 11 from the stop valve 1h under the action of the seawater pump 2b, and the seawater filter 11 can filter part of impurities in the seawater, thereby facilitating the subsequent desalination and reducing the risk of pipeline blockage; the filtered seawater flows through the check valve 8, and the check valve 8 can prevent the seawater from flowing backwards, so that the seawater in the pipeline can flow smoothly; after the seawater flows out from the check valve 8, the seawater enters from the water inlet of the condenser, and the stop valve 1b is in an open state.
Seawater entering the condenser is used as a cooling medium to flow in the inner pipeline of the condenser and flows out from the first water outlet of the condenser. At this time, the sea water flowing out from the first water outlet of the condenser is divided into two branches. Firstly, the water flows to the high-pressure port of the jet pump 6 as the power for vacuumizing the jet pump 6, secondly, the water flows into the evaporator from the second water inlet of the evaporator through the constant-pressure valve 5a, absorbs heat and evaporates to form water vapor. The generated water vapor is filtered by the filter screen 13 and enters a condenser, and the final condensation is completed at the condenser to form desalted water. At the same time, the unevaporated seawater is discharged from the discharge port of the jet pump 6 through the stop valve 1g and the reverse electromagnetic stop valve 10 a.
(3) The seawater which forms vapor is condensed in the condensing chamber through the desalted seawater pipeline, and is discharged from the desalted water outlet of the condenser under the action of the desalted water pump 2 c. The discharged desalted seawater flows through the salinity sensor 9, at this time, the salinity sensor 9 detects whether the salinity in the desalted seawater exceeds a threshold value, if so, the salinity sensor 9 controls the electromagnetic ball valve 10b to be opened and the electromagnetic stop valve 10c to be closed, so that the unsatisfied desalted seawater is discharged out of the device, until the salinity is lower than the threshold value, the salinity controller controls the electromagnetic ball valve 10b to be closed and the electromagnetic stop valve 10c to be opened, and at this time, the desalted seawater can flow into the fresh water tank.
Furthermore, a flowmeter 12 is arranged on a pipeline connected with the fresh water tank through the condenser, so that a user can know the total amount of the seawater which is up to the desalination standard conveniently, and the device is closed in time, so that the total amount of the desalinated seawater is prevented from exceeding the capacity of the fresh water tank.
Further, as shown in fig. 1, the condenser and the evaporator are disposed in the same housing, which is favorable for protecting the condenser and the evaporator from damage, and meanwhile, a safety valve 3a and a vacuum breaking valve 4a are disposed above the housing, so as to avoid the pressure in the device exceeding the threshold value.
Further, as shown in fig. 1, the device is further provided with a viewing mirror 7 for observing the condensation condition in the condenser.
It will be apparent to those skilled in the art that various modifications and variations can be made to the embodiments of the present application without departing from the spirit and scope of the application. In this manner, the present application is also intended to cover such modifications and changes as fall within the scope of the claims of the application and the equivalents thereof. The word "comprising" does not exclude the presence of other elements or steps than those listed in a claim.
