Abstract

The present invention relates to an energy recovery device with a rotary volumetric pressure exchange type, and, more specifically to an energy recovery device with a rotary volumetric pressure exchange type which collects pressure energy of seawater (water hydraulic power) which has been filtered in a reverse osmosis desalination apparatus and condensed without disposing into the sea, and drives a hydraulic motor configured with a hydraulic pump as one body so as to reduce electricity consumption as a separate hydraulic motor is not used, thereby reducing energy waste or increasing efficiency.

Description

[0001] The present invention relates to a rotary type energy recovery device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary volumetric pressure exchange type energy recovering apparatus, and more particularly, to a rotary volumetric pressure exchange type energy recovery apparatus capable of recovering pressure energy (hydraulic power) of concentrated seawater filtered in a reverse osmosis The present invention relates to a rotary volumetric pressure exchange type energy recovery device capable of reducing power consumption without using a separate hydraulic motor by driving a motor and thereby reducing waste of energy or increasing efficiency.

To obtain freshwater from seawater, dissolved or suspended components in seawater should be removed to meet water and drinking water standards.

Such seawater desalination methods include a reverse osmosis membrane method and an electrodialysis method using a special membrane, an evaporation method in which seawater is converted into steam to desalinate, a freezing method, and a solar heat utilization method.

Evaporation using phase change of materials has been widely used for seawater desalination. However, due to the increase in fossil fuel prices and the development of highly efficient low-energy seawater desalination equipment, reverse osmosis and electrodialysis using membranes have been mainly used for seawater desalination .

The seawater desalination plant by reverse osmosis membrane filtration is an ionic material which is dissolved in seawater by using semi-permeable membrane (membrane) in which ionic substance dissolved in water is almost eliminated and pure water is passed through.

In order to separate ionic material from pure water in seawater, high pressure energy above seawater osmotic pressure is required, which is called reverse osmosis pressure, and seawater requires high pressure of 42 ~ 70 bar depending on salinity.

However, since the high pressure is generated and maintained by the separate high-pressure feed pump, the power for driving the high-pressure feed pump is consumed, and the highly concentrated seawater filtered in the reverse osmosis filtration device is directly discharged at high pressure, Is severe.

Therefore, many kinds of pressure recovery mechanisms have been developed and distributed as a means to overcome such shortcomings.

Such a pressure recovery mechanism has turbo type such as pelton aberration and francis aberration. However, since these are low efficiency and large in volume, they can not be used in small-sized devices.
