Description
Technical field
The present invention relates to the energy recycle device in water treatment system.
Background technology
For China's reverse osmosis seawater desalting, the expense of water power consumption processed is the direct factor for determining desalination water cost.Energy
It is one of key equipment of reverse osmosis seawater desalting to measure retracting device, using international advanced energy recycle device（Energy regenerating
Efficiency about 94%）The 50% of conventional reverse osmosis water consumption can be about reduced, but import energy recycle device is expensive, invests into
Originally the 15~21% of reverse osmosis seawater desalination equipment gross investment are accounted for.Develop energy-conservation, efficient domestic energy recycle device production
Product, to the water resources crisis for promoting the production domesticization of desalinization equipment, improving China's desalinization industrial competitiveness, alleviating China
It is significant.
The main function of energy recycle device is to reclaim the pressure energy that reverse osmosis membrane retains side high pressure concentrated seawater, is changed
For water inlet energy, the water consumption processed of reverse osmosis seawater desalting and water cost is made so as to be greatly reduced.According to operation principle, energy is returned
Receiving apparatus is broadly divided into water turbine formula and the major class of Work-exchange type two.The energy of mechanical energy water turbine formula energy recycle device turns
Process is changed for " pressure energy-mechanical energy (shaft work)-pressure energy ", its energy recovery efficiency about 35%~70%.And Work-exchange type energy
Retracting device, is only needed by " pressure energy-pressure energy " one step conversion process, its energy recovery efficiency is up to more than 94%, it has also become
The emphasis of domestic and international research and extension.
At present, in the market rotator type is main based on the PX of ERI companies of the U.S. without piston Work-exchange type energy recovery device,
Its drive rotor rotate power be low pressure seawater and the road water of high pressure concentrated water two to the tangential impulse force of rotor end-face, this is just determined
The rotor of the device must be that gap coordinates with upper and lower biend, and otherwise device can not work.In order that with low viscosity
Gratifying reliability is for example obtained during the fluid of water, it has therefore proved that it is necessary to use ceramic material, but be rotation with ceramics
The main material of part, security and stability is greatly reduced.
PX energy regeneratings are that the high pressure concentrated water for discharging desalinization promotes the ceramic rotor high-speed rotation of multichannel, simultaneously
Directly briefly contacted with low pressure seawater water inlet in 12 passages, make pressure from high pressure concentrated seawater using the Incoercibility of water
It is delivered to low pressure seawater and carries out pressure transmission, reaches the energy regenerating of high pressure concentrated seawater stream.By to high-pressure thick seawater inlet stream
The particular design in road realizes that ceramic rotor is rotated automatically, and rotating speed is higher in normal course of operation, about 1500 revs/min.It is led
The problem of existing be, one is that PX type pressure-exchange formulas are stricter to charging seawater pressure, flowed fluctuation requirement, when flow,
Pressure can influence rotor speed when varying widely, and cause system operation unstable；Two be rotor during running at high speed
The noise sent is larger, about 88-94dB（Provide to require more than national correlated noise standard 85dB）.
The content of the invention
The technical problems to be solved by the invention are to provide driving rotator type energy recycle device outside one kind, can realize good

On, high pressure sea water outlet and low pressure seawater import are located on wherein another of upper and lower end cap；
Friction of two end faces up and down of rotor respectively with upper fixing seal disk, lower fixing seal disk formation relative motion is matched somebody with somebody
Stream is secondary；
It is characterized in that：The energy recycle device is provided with self-balancing self-tightening sealing system, and the self-balancing is from close
Envelope system includes：
It is described not turn in component that the outer ledge of upper valve plate and lower valve plate is provided with a circle compression spring, will be upper
Valve plate and lower valve plate push the end face of rotor to；
Described not turn to be additionally provided with thrust ball bearing in component, the thrust ball bearing is in valve plate and lower valve plate
In between the valve plate that is connected with high-pressure thick water inlet and low-press thick water out and rotor end-face；
It is described not turn to connect with high-pressure thick water inlet and low-press thick water out in upper valve plate and lower valve plate in component
Valve plate and upper end cover and bottom end cover in set and formed and high pressure between the end cap of high-pressure thick water inlet and low-press thick water out
The high pressure chest of concentrated water inlet communication.
Further, be cased with central seal sleeve on the central shaft, its two ends is respectively equipped with sealing ring, with respectively and
The flow center hole connected in upper valve plate and lower valve plate with setting high-pressure thick water inlet and low-press thick water out and upper end
