Description

Technical Field

[0001] This utility model relates to the field of concentrated water energy recovery and reuse technology in demineralized water systems, specifically a demineralized water energy recovery device. Background Technology

[0002] A demineralized water system is an industrial water treatment system that removes impurities such as ions, colloids, and microorganisms from water using physical, chemical, and membrane separation technologies to produce high-purity water.

[0003] However, the demineralized water system in the current project has some drawbacks in actual use: the concentrated water produced by the existing demineralized water system is mostly discharged directly into the drainage ditch or into the concentrated water tank. This results in very low or almost no utilization of the concentrated water, leading to energy waste.

[0004] To address these issues, we designed a demineralized water energy recovery device. Utility Model Content

[0005] The purpose of this invention is to provide a demineralized water energy recovery device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides a demineralized water energy recovery device, including a reverse osmosis security filter. An inlet pipe is fixedly inserted into the top of one side of the reverse osmosis security filter. A reverse osmosis high-pressure pump is installed on the side of the reverse osmosis security filter away from the inlet pipe. A housing is installed at the outlet end of the reverse osmosis high-pressure pump. A reverse osmosis membrane is installed inside the housing. An L-shaped pipe is fixedly inserted into the bottom of the front side of the housing. A hydroelectric power generation component is installed at the other end of the L-shaped pipe. One side of the hydroelectric power generation component is electrically connected to an electrical device.

[0007] Furthermore, the hydroelectric power generation component includes at least a hydroelectric generator, the water inlet of which is fixedly connected to the end of the L-shaped pipe away from the casing.

[0008] Furthermore, the hydropower generation component also includes a rectifier and a battery, and the hydropower generator, rectifier, and battery are all electrically connected to each other.

[0009] Furthermore, the hydroelectric power generation component also includes a voltage regulator, which is electrically connected to the rectifier and the battery.

[0010] Furthermore, the hydroelectric power generation component also includes an inverter, which is electrically connected to a battery.

[0011] Furthermore, the hydroelectric generator, electrical equipment, rectifier, voltage regulator, battery, and inverter are all electrically connected via copper wires.

[0012] Furthermore, a Z-shaped tube is fixedly inserted into the side of the housing away from the reverse osmosis high-pressure pump, and a reverse osmosis permeate collection tank is provided at the other end of the Z-shaped tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the concentrated water produced after treatment enters the water conservancy generator through the L-shaped pipe. At this time, the water conservancy generator converts the kinetic energy of the water into mechanical energy through the high-speed rotation of the impeller, and then into AC power, which can be used by electrical equipment, thus realizing energy saving, emission reduction and energy conversion and reuse.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting up a rectifier, since the generated electrical energy is alternating current, in order to facilitate the storage of electrical energy, we need to connect the alternating current generated by the hydroelectric generator to the rectifier, so that the alternating current can be converted into direct current.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting a voltage regulator, since the AC power through the rectifier is only converted into unidirectional pulsating voltage and current, the latter has a large AC component, in order to ensure the safety of the battery, it is also necessary to connect a voltage regulator to stabilize the voltage and convert the pulsating DC power into stable DC power.

[0016] Compared with the prior art, the beneficial effects of this utility model are: by setting up an inverter, since the subsequent electrical equipment uses constant voltage AC power, we need to connect the DC power stored in the battery to the inverter, and then the inverter generates the constant voltage AC power required by the equipment for the equipment to use.

[0017] Compared with the prior art, the beneficial effects of this utility model are: by setting up a storage battery, since the subsequent electrical equipment is not always in working state, or the electrical equipment in working state uses less electricity than generated, it is necessary to set up a storage battery after the voltage regulator to store the DC power processed by the voltage regulator.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a demineralized water energy recovery device, including a reverse osmosis security filter 1, an inlet pipe 2 fixedly inserted into the top of one side of the reverse osmosis security filter 1, a reverse osmosis high-pressure pump 3 arranged on the side of the reverse osmosis security filter 1 away from the inlet pipe 2, a housing 4 arranged at the outlet end of the reverse osmosis high-pressure pump 3, a reverse osmosis membrane arranged inside the housing 4, an L-shaped pipe 5 fixedly inserted into the bottom of the front side of the housing 4, a hydroelectric power generation component arranged at the other end of the L-shaped pipe 5, an electrical device 7 electrically connected to one side of the hydroelectric power generation component, the hydroelectric power generation component including at least a hydroelectric generator 6, the inlet end of the hydroelectric generator 6 fixedly connected to the end of the L-shaped pipe 5 away from the housing 4, the hydroelectric power generation component also includes a rectifier 8 and a battery 10, the hydroelectric generator 6, the rectifier 8 and the battery 10 are all electrically connected to each other.

[0025] In practice, the concentrated water produced by the treatment enters the hydroelectric generator 6 through the L-shaped pipe 5. During this process, the hydroelectric generator 6 converts the kinetic energy of the water into mechanical energy through the high-speed rotation of the impeller, and then into AC power, which can be used by the electrical equipment 7, thus realizing energy conservation, emission reduction and energy conversion and reuse.

[0026] It should be noted that when the demineralized water system produces concentrated water, after the concentrated water is connected to the hydraulic generator 6, the pressure of the incoming water is still about 1 MPa. The hydraulic generator 6 can then use the kinetic energy brought by this pressure of about 1 MPa to drive the generator impeller to rotate at high speed to generate mechanical energy. Then, through the internal structure of the hydraulic generator, the mechanical energy is converted into electrical energy (alternating current). Since the hydraulic generator 6 is existing technology, it will not be elaborated on further.

[0027] In addition, for the storage battery 10, since the subsequent electrical equipment 7 is not always in working condition, or the electrical equipment 7 in working condition uses less electricity than it generates, a storage battery 10 needs to be set after the voltage regulator 9 to store the DC power processed by the voltage regulator 9.

[0028] See Figure 1-4 The hydroelectric power generation component also includes a voltage regulator 9, which is electrically connected to the rectifier 8 and the battery 10.

[0029] In specific implementation, based on the above implementation, by setting up a voltage regulator 9, since the AC power through the rectifier 8 is only converted into unidirectional pulsating voltage and current, the latter has a large AC component, in order to ensure the safety of the battery 10, it is also necessary to connect the voltage regulator 9 to stabilize the voltage and convert the pulsating DC power into stable DC power.

[0030] See Figure 1-4 The hydroelectric power generation component also includes an inverter 11, which is electrically connected to a battery 10.

[0031] In specific implementation, based on the above implementation, by setting up inverter 11, since the subsequent electrical equipment 7 uses constant voltage AC power, we need to connect the DC power stored in the battery 10 to inverter 11, and then the inverter 11 generates the constant voltage AC power required by the equipment for the equipment to use.

[0032] See Figure 1-4 The hydroelectric generator 6, electrical equipment 7, rectifier 8, voltage regulator 9, battery 10, and inverter 11 are all electrically connected via copper wires. Copper wires result in lower energy loss and less heat generation, thus saving energy and reducing the risk of fire.

[0033] See Figure 1-4 A Z-shaped tube 12 is fixedly inserted into the side of the casing 4 away from the reverse osmosis high-pressure pump 3, and a reverse osmosis permeate collection tank 13 is provided at the other end of the Z-shaped tube 12. The treated permeate is injected into the reverse osmosis permeate collection tank 13 through the Z-shaped tube 12 for production use.

[0034] Working principle: During use, the incoming water first enters the reverse osmosis security filter 1 through the inlet pipe 2 for coarse filtration to remove large impurities. Then, it is pumped to the housing 4 by the reverse osmosis high-pressure pump 3 and further treated by the reverse osmosis membrane. The treated product water is then injected into the reverse osmosis product water collection tank 13 through the Z-shaped pipe 12 for production use. The concentrated water produced enters the hydroelectric generator 6 through the L-shaped pipe 5. During this process, the hydroelectric generator 6 converts the kinetic energy of the water into mechanical energy through the high-speed rotation of the impeller, and then into alternating current (AC) energy. The AC energy is then converted into unidirectional pulsating direct current (DC) through the rectifier 8, and then connected to the voltage regulator 9 for voltage regulation. The regulated DC energy is then connected to the storage battery 10 for energy storage. When the stored energy in the storage battery 10 needs to be used, it is necessary to connect the storage battery 10 to the inverter 11 to convert the DC energy back into AC energy. Finally, it can be connected to the electrical equipment 7 for use, achieving energy saving, emission reduction, and energy conversion and reuse.

[0035] It should be noted that when the demineralized water system produces concentrated water, after the concentrated water is connected to the hydraulic generator 6, the pressure of the incoming water is still about 1 MPa. The hydraulic generator 6 can then use the kinetic energy brought by this pressure to drive the generator impeller to rotate at high speed and generate mechanical energy. Then, through the internal structure of the hydraulic generator, the mechanical energy is converted into electrical energy (alternating current). Since the hydraulic generator 6 is existing technology, it will not be elaborated on further.
