Supercharger with stagger hydraulic pistons of staggered channels on hollow rotor

Abstract

The invention discloses a supercharger with stagger hydraulic pistons of staggered channels on a hollow rotor. The supercharger is characterized in that the hollow rotor is provided with airtight axis space; at least two rings of equant and stagger channel units are adopted on the periphery of the airtight axis space; each ring is provided with a plurality of channel units; the minimum radial size of each channel unit on the outer ring is smaller than the maximum radial size of each channel unit on the inner ring, thus forming a radial stagger form; the channel units on the outer ring and the channel units on the inner ring are arranged on the circumference in an equant, stagger and radial manner, thus forming a circumferential stagger form; and a high pressure water filtration chute and a pressure relief water filtration chute are symmetrically arranged on a lower end cover, and a pressure raising raw water chute and a low pressure raw water chute are symmetrically arranged on an upper end cover, thus forming two inlet and two outlet oblique runners. The supercharger has the following beneficial effects that the hollow rotor can be freely rotated to complete runner switching and realize pressure exchange by virtue of the forces applied by the oblique runners to the two end faces of the hollow rotor, without being controlled by any external electrical appliance, switch valve and other components; and any electrical appliance accident is also avoided.

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 piston staggered 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...

Problems solved by technology

The disadvantage is that the working liquid medium is in direct contact with the waste high-pressure liquid, which can only be limited to the occasion where the working liquid medium is the same as the waste high-pressure liquid, and there is a large flow and small diameter energy transfer, and the pipeline consumes a lot of energy; The energy transfer of the radial structure, the mixing surface is difficult to control, its efficiency is low and the quality of the transfer is severely reduced, especially the two adjacent pressure exchange channels of the rotor are radially separated by a straight plate, and the unreasonable pressure bearing structure causes the partition wall The increase in thickness leads to a very low effective pressure exchange channel rate per unit volume of the pressure exchanger, and the pressure loss caused by the thick part of the partition wall to the liquid flow is large, and the actual efficiency is often lower than 80%.

Generally, only multiple small diameter and long pipes can be connected in parallel, which makes the system huge, complex project investment and difficult to manage and coordinate
