[2] The present invention is characterized in that fresh water can be produced without using any electric energy and fuel oil equipment, and in any place where there is a sea wave, the power generated by the waves can be used, and the wave energy desalination machine can be used to produce fresh water by itself.

Background technique

[3] At present, desalination equipment on large ships uses large industrial equipment for desalination, while fresh water for small boats is supplied by ship and logistics. The freshwater of the People's Liberation Army warriors guarding the islands far from the mainland are regularly transported by mainland life ships. Install industrial equipment on boats and small islands to make fresh water. The equipment that produces fresh water must use electricity or fuel to desalinate seawater and produce fresh water. In the state of the sea environment, fuel and electricity supply are subject to transportation conditions, so the freshwater supply of soldiers stationed on the island for a long time is subject to certain conditions. In the state of war, the loss of electricity and fuel supply will result in the loss of fresh water supply. The freshwater supply of the island is in trouble and directly affects the survival of the soldiers. Similarly, when the small ship Linyi extended the offshore operation, the fresh water carried will be very difficult once it is used up. Therefore, in the state of the sea environment where there is no energy supply such as electricity and fuel, and how to solve the water supply problem for the Shoudao fighters in the very long period of war, how to extend the water supply for the warriors on the dinghy, how to be a fishing boat Supplying fresh water, how to supply water to workers on oil rigs is a costly and important job, and it is also a tedious and complicated work.

[4] The invention is characterized in that fresh water can be produced without using any electric energy and fuel equipment, and the fresh water can be produced by using the power generated by the waves in any place with sea waves and using the wave energy desalination machine. The world's coastline is long and the number of shore residents is huge. Using the present invention to provide edible fresh water can save huge energy.

Disclosure of invention

Technical solution

[5] The wave energy desalination machine of the invention is used in the field of seawater desalination. Use solar energy and wave kinetic energy as well as low The physical process of atmospheric boiling evaporation reaches the goal of desalination and production of fresh water.

[6] At sea, 10 cm, 50 cm, 1 m, 3 m high waves can be seen everywhere, everywhere. These waves are valuable mechanical energy, providing a reliable source of energy for large-scale production of fresh water. In any place with waves, use the power generated by the waves and use the wave energy desalination machine to produce fresh water by yourself.

[7] The invention can be used for small-sized equipment to meet the fresh water supply of about 10 people. If it is made into a large-sized equipment and formed into an array installation, it can supply fresh water demand of hundreds of people.

[8] The invention can be installed next to a sea reef, a shallow beach, a ship's side, a cave through the sea, and an anchor floating on the surface of the sea.

[9] This device uses only solar energy and wave kinetic energy to fully meet environmental requirements.

[10] The present invention uses solar radiant heat to heat seawater. In the case of the sun, sunlight illuminates the metal casing of the seawater evaporation chamber, heating the casing and transferring the heat to the metal mesh in the seawater evaporation chamber. When seawater flows through the metal heating grid, it is heated and produces fresh water vapor.

[11] The present invention uses the undulating power of seawater to push up and down the float chamber. The thrust float chamber converts the kinetic energy of the waves into mechanical energy, which pushes the pump piston and the fresh water vapor collection piston to reciprocate and produce fresh water.

[12] In the absence of sunlight, only low-pressure boiling evaporation technology can be used to produce fresh water.

[13] The overall structure of the wave energy desalination machine of the present invention comprises a seawater evaporation chamber assembly, a fresh water collection chamber assembly, a water pump assembly, a thrust float chamber assembly, a bottom fixing rod, a condensing tube assembly; a bottom fixing rod and The water pump assembly is fixed together, and the water pump piston in the water pump assembly is installed on the thrust float chamber of the thrust float chamber assembly through a connecting member, and the water outlet of the water pump assembly is connected to the spray water hole of the seawater evaporation chamber assembly through the seawater conduit. The seawater evaporation chamber assembly is connected to the fresh water collection chamber assembly, and the seawater evaporation chamber assembly is further provided with a high-salt seawater outlet, and the fresh water collection chamber assembly fresh water vapor outlet valve is in communication with the condensation tube assembly.

[14] Among them:

[15] The seawater evaporation chamber assembly consists of a seawater evaporation chamber, a heat absorption net, a water volume control valve, a jet water hole, and a high-salt seawater exhaust valve.

[16] The fresh water collection room assembly consists of fresh water collection chamber, fresh water collection piston, piston ring, fresh water vapor inlet valve, fresh water vapor outlet valve, hose, fresh water piston connecting rod, upper connecting rod shaft, chute steel tube and other components.

[17] The pump assembly consists of a pump chamber, a water pump piston, a water pump connecting rod, a piston pin, a piston ring, an inlet valve, and a water conduit. , seawater pressure limiting valve and other components.

[18] The thrust float chamber assembly consists of a float chamber shell, a float chamber counterweight, and a float push rod.

[19] The bottom fixing rod consists of iron rods and iron rod tips.

[20] The condensing tube assembly consists of a metal condensing coil.

[21] The seawater evaporation chamber is where the two technologies of solar heating and low-pressure boiling evaporation work together. The outer shell of the seawater evaporation chamber is a solar collection surface. The sun shines on the surface of the evaporation chamber, and the outer shell of the seawater evaporation chamber made of stainless steel iron is heated by solar energy to heat the seawater flowing through the heating net in the evaporation chamber to evaporate the seawater. At the same time, when the vacuum suction generated by the fresh water collection chamber acts in a low-pressure environment in the seawater evaporation chamber, a low-pressure boiling effect is generated, and more fresh water vapor is generated. A large amount of fresh water vapor is generated by the superposition of both solar energy and low pressure evaporation technology, and these fresh water vapors are sucked into the fresh water collection chamber.

[22] The freshwater collection room is where fresh water vapor is collected. When the waves fall, the thrust float chamber moves downward, driving the fresh water vapor collecting piston to move downward, and the fresh water collecting chamber increases in space, which lowers the air pressure in the fresh water collecting chamber. A pressure difference is formed between the seawater evaporation chamber and the fresh water collection chamber, the fresh water vapor inlet valve is opened, and the fresh water vapor in the seawater evaporation chamber enters the fresh water collection chamber. When the fresh water piston continues to descend, the fresh water collection chamber forms a vacuum suction effect, causing the seawater in the seawater evaporation chamber to boil and evaporate under a low pressure state, forming a large amount of water vapor. These large amounts of fresh water vapor are sucked into the fresh water collection room.

[23] The waves rise again, the thrust float chamber moves upwards, the fresh water collecting piston moves upward again, compresses the space of the fresh water collection chamber, the fresh water vapor inlet valve closes, the fresh water vapor outlet valve opens, and the fresh water collection is under the pressure of the fresh water collecting piston The fresh water vapor in the room is pressed into the condenser and condensed into fresh water.

[24] The pump room is the device that transports seawater to the seawater evaporation chamber. In the thrust float chamber, the fresh water collecting piston is moved upward again, and the driving pump piston moves upwards, passes through the seawater conduit, and presses the seawater into the water regulating valve, and then injects through the eight water injection holes around the water injection regulating valve. In the endothermic metal mesh at the top of the seawater evaporation chamber, the seawater is heated by the endothermic metal mesh and flows into the seawater evaporation chamber to prepare for the new formation of seawater vapor.

[25] The pump chamber is the control device for the high-salt seawater discharge valve. When the water pump rises, the seawater pressure generated by the pump piston is transmitted to the high-salt seawater discharge valve through the seawater conduit, and the high-salt seawater discharge valve is opened to remove the evaporated high-salt seawater from the evaporation chamber. The pump piston descends and the seawater in the seawater conduit loses pressure. The high-salt seawater discharge valve is closed, so that the seawater evaporation chamber forms a closed environment, and a new process of solar radiation heating and low-pressure boiling evaporation of fresh water vapor is generated.

[26] The thrust float chamber is a component that transforms the kinetic energy of the waves and pushes the freshwater collecting piston and the pump piston up and down.

As the waves rise, the buoyancy of the sea pushes the thrust float chamber up, pushing the freshwater collecting piston and the pump piston upward through the float pusher. As the waves descend, the thrust float chamber loses its buoyancy. Under the gravity of the thrust float chamber and the float chamber counterweight, the float pusher pushes the fresh water collecting piston and the water pump piston downward.

[27] The bottom fixing rod is composed of iron rods and iron rod tips. The iron rods are inserted into the bottom soil of the seabed beach, and the fixed wave energy seawater desalination machine body. The sea water is undulating, the whole body does not move, but the thrust float chamber moves up and down with the sea water. Fresh water can be produced by fixing the fuselage to the seabed by a large pontoon and an anchor chain, and floating the floating float of the wave energy desalination machine to the sea surface. The present invention can produce fresh water in any sea area that does not freeze.

[28] The condensing tube assembly consists of a condensing coil. Use seawater to cool fresh water vapor. When the next fresh water vapor is pushed into the condenser, the thrust is generated and the condensed fresh water is discharged into the fresh water tank.

[29] The cycle of the specific work of the present invention is as follows:

[30] First, the waves rise, and the buoyancy of the sea pushes the thrust float chamber up. The thrust float chamber pushes the fresh water collection piston and the pump piston up. Its role is as follows:

[31] 1. The fresh water collecting piston is uplifted to compress the fresh water to collect the indoor space volume and press the fresh water vapor in the room into the fresh water condenser.

[32] 2. The pump piston is lifted up, the seawater is pressed into the pump chamber, flows through the seawater conduit, and the seawater is pressed into the water volume regulating valve, and then injected into the top of the seawater evaporation chamber through the water injection hole around the water injection regulating valve. In the heating network, the newly injected seawater is heated by the heat absorption net and flows into the seawater evaporation chamber, and generates fresh water hot steam due to heat.

[33] 3. The water pressure generated by the pump piston is transmitted to the high-salt seawater discharge valve through the seawater conduit, and the high-salt seawater discharge valve is opened to remove the evaporated high-salt seawater from the evaporation chamber.

[34] Second, the waves fall, the thrust float chamber loses the wave buoyancy, and the thrust float chamber acts under the gravity of the float chamber counterweight, pulling the fresh water collecting piston and the pump piston down. Its role is as follows:

[35] 1. The pump piston descends, the seawater in the seawater pipe loses pressure, and the high-salt seawater discharge valve closes, which makes the seawater evaporation chamber form a closed environment, and generates a new process of solar radiation heating and low-pressure boiling evaporation of fresh water vapor. [36] 2. The fresh water collecting piston descends due to the increased volume of the fresh water collecting chamber, and again creates a vacuum low pressure in the fresh water collecting chamber. The vacuum suction valve creates a vacuum suction in the seawater evaporation chamber and forms a low pressure environment in the seawater evaporation chamber. . The seawater heated by solar energy is further subjected to low pressure boiling evaporation in a low pressure environment in the seawater evaporation chamber to produce more fresh water.

[37] 3. As the freshwater collecting piston continues to descend, the volume of the fresh water collection chamber continues to increase, and the vacuum suction is generated by the fresh water vapor inlet valve, and the fresh water vapor generated in the seawater evaporation chamber is sucked into the fresh water collection chamber.

[38] 4. The pump piston descends and once again draws seawater into the pump room to prepare for the next seawater transport.

[39] Third, as the seawater rises again, the cycle takes the first step of the rise of the waves. As the waves continue to rise and fall, the wave energy desalination machine continuously reciprocates and reproduces a steady stream of fresh water.

Beneficial effect

[40] A feature of the present invention is that fresh water can be produced without using any electrical energy and fuel equipment. Fresh water can be produced by itself in any place with waves, regardless of the environment and conditions, and it is convenient for soldiers who guard the island. Especially in the bad state of war, power, fuel and other energy sources have lost supply. The island can also produce fresh water by itself, and still supply fresh water to naval warriors.
