Description
Technical Field
The invention belongs to the technical field of energy recycling, and particularly relates to an energy recycling device for energy exchange between a pressurizing liquid and a pressurized liquid.
Background
Reverse osmosis seawater desalination is an important technology for solving the shortage of fresh water resources, and has been popularized and applied in global coastal areas. In order to obtain higher desalted water recovery rate in the technical process, the high-pressure seawater pressure at the inlet of the reverse osmosis membrane unit is usually required to be as high as 5.5-6.0MPa, so that the energy consumption for system operation is huge. Meanwhile, the pressure of the high-pressure brine discharged from the reverse osmosis membrane unit device is higher than 5.0MPa, and if the brine is discharged directly through a pressure reducing valve, the system energy is wasted greatly. After the energy recovery device is used, the pressure energy stored in the high-pressure brine discharged by the reverse osmosis membrane group device is reused and transferred to the low-pressure fresh seawater, and the operation energy consumption of the reverse osmosis seawater desalination system can be reduced by more than 50 percent according to the desalination water recovery rate estimation of 40 percent.
The hydraulic turbine device is an energy recovery device product which is firstly applied to a reverse osmosis sea water desalination system, the engineering amplification performance of the device product is good, the single-machine treatment amount is up to hundreds of tons per hour, and the greatest disadvantage is that the energy conversion process needs to be subjected to two steps of pressure energy-shaft work-pressure energy, and the comprehensive energy recovery efficiency of the device is relatively low and is only 50-80%. The positive displacement energy recovery device, especially the rotor energy recovery device product, has been rapidly applied in sea water desalination engineering for more than ten years, which uses pascal isopiestic principle to directly transfer the pressure energy in the high pressure brine discharged by reverse osmosis membrane device to low pressure fresh sea water, the energy recovery efficiency of the device is up to more than 94%, and the device becomes the key product for domestic research and popularization and application.
However, in the disclosed rotor type energy recovery device, hydraulic force is required to drive the rotor member to rotate, and fluid subjected to pressure exchange in the rotor duct is also driven to rotate, which results in high hydraulic drive energy consumption. The device can be regulated only in a narrow operating load to ensure higher efficiency of the device due to the limitation of the rotation speed of the rotor and the mixing degree of the brine in the pore canal. Engineering magnification will increase rotor rotational instability and complexity of hydraulic drive, and current rotor energy recovery devices have low single machine throughput.

At the same time, the other 5 spool rods 22 corresponding to the pressurized fluid outflow collection grooves 16-4 are in the process of depressurization. The spool plunger rod 22 during pressurization and the spool plunger rod 22 during depressurization will constitute a lever movement mechanism by means of a contact connection of the balancing disk 23. The spool plunger rod 22 at the other end of the balance disc 23 will move upward simultaneously while the spool plunger rod 22 in the pressurizing process moves downward under the pushing of the pressurizing liquid.
The slide valve plunger rod 22 at the other end of the balance disc 23 moves upwards, so that the circulation window 22-1 of the slide valve plunger rod 22 is communicated with the upper circulation window 21-1 of the slide valve guide tube 21, pressurized liquid enters the pressurized liquid inflow cavity through the pressurized liquid inlet 19 on the cylinder body 1, enters the 5 pressure exchange cylinders 20 corresponding to the 5 continuous through-flow channels 18-1 covered by the pressurized liquid outflow collecting groove 16-4 of the liquid switching turntable 16 through the upper circulation window 21-1 of the slide valve guide tube 21 and the circulation window 22-1 of the slide valve plunger rod 22, and flows the pressurized liquid decompressed in the 5 pressure exchange cylinders 20 through the pressurized liquid outflow collecting groove 16-4, the pressurized liquid outflow channel 16-6 and the central hole 16-1 in sequence, flows into the pressurized liquid outflow cavity and finally is discharged out of the device through the pressurized liquid outlet 13, which is a decompression process.
With each rotation of the liquid switching dial 16, each pressure exchange cylinder 20 will perform 1 pressurizing stage, 1 sealing interval stage, 1 pressure release stage and 1 sealing interval stage in sequence, so that the pressure of the pressure-applied liquid can be continuously recycled, and at the same time the pressure-applied liquid after pressure release can be continuously discharged out of the device.
It should be noted that, as shown in fig. 8, according to the movement law of the balance disc 23, the 5 pressure exchange cylinders 20 covered by the pressure liquid inflow distribution groove 16-3 are simultaneously in the pressurizing process, but the flow-through windows 22-1 of the 5 spool plunger rods 22 corresponding to the 5 pressure exchange cylinders 20 and the lower flow-through windows 21-2 of the spool guide pipes 21 have overlapping degrees of different magnitudes. Likewise, the 5 pressure exchanger cylinders covered simultaneously by the pressurized fluid outflow collecting tank 16-4 are simultaneously in the pressure release process, but the flow through windows 22-1 of the 5 spool rod 22 corresponding to the 5 pressure exchanger cylinders 20 and the upper flow through window 21-1 of the spool pipe 21 also have different degrees of overlap.
