Hollow rotor misalignment channel hydraulic rotary piston multi-pass supercharger

Abstract

The invention discloses a hollow rotor misalignment channel hydraulic rotary piston multi-pass supercharger. Two ends of a cylinder shell are provided with end cover flanges, and the outer edges of the end cover flanges are provided with flange bolts; inner hole threads of the end cover flanges are respectively connected with screw cover outer threads of fastening adjusting screw covers at two ends of the cylinder shell; and the inner end surfaces of the fastening adjusting screw covers are respectively used as outer end planes of a lower end cover and an upper end cover, the outer circles of the lower end cover and the upper end cover, which are provided with sealing ring grooves, are matched with inner holes at two ends of the cylinder shell, the lower cover inner plane of the lower end cover and the upper cover inner plane of the upper end cover tightly lean against transition platform shoulders between middle section inner holes of the cylinder shell and the inner holes at the two ends of the cylinder shell, and an upper end cover mandril and a lower end cover mandril which are movably fixed on the lower end cover and the upper end cover are used for supporting the whole hollow rotor to rotate freely. By virtue of force applied to two end surfaces of the hollow rotor by an oblique flow channel, the hollow rotor can rotate freely without being controlled by components, such as a valve driven and switched by any external electric device, thus flow channel switching can be finished, and pressure exchanging can be realized.

Description

technical field [0001] The invention belongs to the field of energy transmission equipment, and in particular relates to a hollow rotor dislocation channel hydraulic rotary 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...

Problems solved by technology

[0006] 3. The earliest and most successful developed countries that invested in seawater desalination, such as Japan, Denmark, Netherlands, Sweden, Norway, the United Kingdom, the United States, and Germany, have all made efforts in pressure exchange, but their highest exchange efficiency has not exceeded 95 %, and the supporting project is huge, too many control components such as external electrical drive and switching valves lead to frequent accidents, which eventually lead to a substantial increase in equipment investment and additional costs such as daily management and maintenance
