Misplaced channel free-rotating hydraulic piston multipass supercharger

Abstract

The invention discloses a misplaced channel free-rotating hydraulic piston multipass supercharger. End cover flanges are arranged at both ends of a cylindrical shell of the misplaced channel free-rotating hydraulic piston multipass supercharger; flange bolts are arranged at the outer edges of the end cover flanges; inner hole screw threads of the end cover flanges are connected with cap nut external screw threads of fastening regulating cap nuts at both ends of the end cover flanges respectively; inner end faces of the fastening regulating cap nuts are outer end planes of a lower end cover and an upper end cover respectively; the excircles of grooves of the lower end cover and the upper end cover are provided with sealing rings and are matched with inner holes at both ends of the cylindrical shell; a lower cover inner plane of the lower end cover and an upper cover inner plane of the upper end cover are abutted against transition shoulders of an inner hole at the middle section of the cylindrical shell and the inner holes at both the ends of the cylindrical shell; and an integral through rotor is supported and fixed by spigot shafts movably fixed on the lower end cover and the upper end cover to freely rotate. By the force application of inclined flow passages to both end faces of the through rotor, the through rotor can freely rotate without being driven by any external electrical appliance or being controlled by elements such as a switching valve, so that the switching of the flow passages is completed and the pressure exchange is implemented; and meanwhile, an unexpected accident to any electrical appliance is also avoided.

Description

technical field [0001] The invention belongs to the field of energy transmission equipment, and in particular relates to a dislocation channel self-rotating hydraulic piston multi-pass supercharger related to energy recovery equipment in a reverse osmosis seawater desalination system. Background technique [0002] With the advancement of science and technology, the population is increasing day by day, and people's desire to develop into the ocean is becoming stronger and stronger. Seawater desalination treatment is becoming more and more popular, and the energy consumption cost of seawater desalination has received special attention. Early seawater desalination used distillation, such as multi-stage flash technology, with an energy consumption of 9.0kWh / m3, and was usually only built in areas with low energy prices, such as Middle East oil countries, or areas where waste heat was available. In the 1970s, reverse osmosis seawater desalination technology was put into use and h...

[0006] 3. Other forms - Other developed countries that invested in seawater desalination earlier in the world, such as Germany, Japan, the United Kingdom, the United States, the Netherlands, Sweden, Norway, and Denmark, have not achieved ideal and perfect pressure exchange. structure, its highest exchange efficiency does not exceed 95%, and the supporting project is huge, and there are too many control components such as external electrical drives and switching valves, which lead to frequent accidents, which eventually lead to a substantial increase in equipment investment and additional costs such as daily management and maintenance.
