Abstract
The invention aims at providing a two-layer double-volute energy transfer actuator which can make up for the defects of the prior art, not only can efficiently recycle excess pressure energy of high-pressure strong brine in treatment process of a reverse-osmosis seawater desalination system, but also can achieve less or free maintenance of energy transfer actuation equipment. The two-layer double-volute energy transfer actuator comprises a two-layer double-volute working chamber shell 1 and a double-acting cavity impeller 2. The structure is compact due to the two-layer double-volute working chamber shell 1. The adopted symmetrical structure arrangement of two volute working chambers has the advantage that the radial stress of the double-acting cavity impeller 2 is balanced. The adoption of a thickness regulation ring 25 has the advantage that the double-acting cavity impeller 2 can be suspended between two-phase liquid without supporting of an impeller shaft, thus eliminating power consumption of any sealing friction resistance, and hidden maintenance hazard. At least three spherical positioning balls 3 are arranged in an annular space formed by a semicircular positioning groove 14 and a semicircular positioning groove 2 correspondingly, so as to ensure the accurate running of the system.
Description
Technical field
The invention belongs to power delivery device field, be specifically related in reverse osmosis seawater desalination system about the two-layer double-volute energy transfer actuator of the one of apparatus for energy recovery.
Background technique
Energy transferring is found everywhere in field of chemical engineering, especially carries out pressure-exchange to liquid.In Chemical Manufacture, often there are some waste liquids also to possess suitable high pressure before discharging, very large waste can be caused if be not used.The in advance supercharging of energy as liquid working medium can be obtained from discarded high-pressure liquid, a large amount of energy consumption costs can be saved thus, realize the object of energy-saving and emission-reduction.Along with scientific and technological progress, population is increasing, and people are also increasingly strong to the hope of ocean development, and desalination of sea water process is increasingly universal, and the energy consumption cost of desalination of sea water is subject to special concern.
Early stage desalination of sea water adopts the way of distillation, and as multi-stage flash evaporation technology, energy consumption, at 9.0kWh/m3, only build the very low area of energy cost in usually, as Middle East petroleum state, or has the available area of used heat.
20 century 70 Reverse-osmosis Seawater Desalination Technologies drop into application, through updating.The process energy consumption 6.0kWh/m3 of the most reverse osmosis seawater desalination systems built up before the beginning of the eighties, energy consumption 3.0kWh/m3 by now, its topmost improvement be by process after high-pressure thick salt solution Energy Efficient recycle, therefore, energy recovery efficiency has become the key reducing desalination of sea water cost.
The world today mainly contains following three kinds at the energy transferring actuating equipment that field of seawater desalination liquid energy is recycled:
1, traditional piston hydraulic cylinder similar plunger pump; advantage is that liquid working medium does not directly contact with discarded highly pressurised liquid; peak efficiency can reach 95%; the piston of shortcoming hydraulic cylinder structure and piston rod self have very large friction power loss; the particularly the most difficult ideal effect that reaches of reciprocation sealing technology of piston rod; practical efficiency is often lower than 90%, and particularly frictional loss causes that equipment downtime is frequent, maintenance cost is high.The patent No.: 201010122952.2, in China's patent of invention that on July 21st, 2010 announces: for differential energy recovery device and the method for seawater desalination system, just belong to conventional piston hydraulic cylinder structure;
The energy delivery devices of 2, turbine---water pump selection, outstanding advantages is stable and reliable operation, liquid working medium does not directly contact with discarded highly pressurised liquid, and large discharge energy transferring can be adapted to, although the peak efficiency of unit is lower than 75%, the efficiency of the energy delivery devices unit after combination generally only has 40%---and 55%, still extensively adopted by Large Copacity seawater desalination system so far.The task of top priority how to reduce seal friction, improves unit efficiency;
3, American Power in 1997 reclaims company (ERI) and releases pressure exchange energy reclaiming device (PressureExchanger), uses the principle switching energy of positive displacement.Advantage is without mechanical motion part, and the highest reuse efficiency of its pipe with small pipe diameter long tube structure can reach 95%.Shortcoming is that liquid working medium directly contacts with discarded highly pressurised liquid, can only be limited to and be applied in the liquid working medium occasion identical with discarded highly pressurised liquid, and there is large discharge pipe with small pipe diameter energy transferring, and its pipeline energy consumption is large; And for the energy transferring of Large Diameter Pipeline structure, flour mixed with adulterants is difficult to control, its efficiency is obviously lower, and Transfer Quality declines severe, and practical efficiency is often lower than 85%.The multiple pipe with small pipe diameter long tube of general employing is in parallel, and seem that system is huge, construction investment complexity is also difficult to management coordination, therefore can only be applicable to small capacity seawater desalination system.
