Misalignment channel autorotation hydraulic rotary piston supercharger

Abstract

The invention discloses a misalignment channel autorotation hydraulic rotary piston supercharger. An autorotation hydraulic rotary piston is provided with a piston center through hole, at least two rings of channel units which are in staggered arrangement are adopted at the periphery of the piston center through hole, each ring is provided with multiple channel units, the minimum radial dimension of each outer ring channel unit is less than the maximum radial dimension of each inner ring channel unit, and thus radial misalignment is formed; outer ring channel units and inner ring channel units are in uniform misalignment radiation arrangement on the circumference, and thus circumference misalignment is formed; a lower end cover is provided with a high-pressure water filtering oblique channel and a pressure-relieving water filtering channel which are in symmetrical arrangement; an upper end cover is provided with a pressure-boosting raw water oblique channel and a low-pressure raw water channel which are in symmetrical arrangement, and thus a two-inlet two-outlet oblique channel is formed. By virtue of forces applied to two end surfaces of a hollow rotor by an oblique flow channel, the hollow rotor can rotate freely without being controlled by any components by means of driving and switching a valve by an external electric device and the like, thus flow channel switching can be finished, pressure exchanging can be realized, and accident of any electric device is prevented.

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 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 has been con...

[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.
