Efficient reverse osmosis seawater desalting plant

Abstract

The invention discloses an efficient reverse osmosis seawater desalting plant, which comprises an inlet valve for seawater to flow in, a water supply pump connected with a water outlet of the inlet valve, a sand filter connected with a water outlet of the water supply pump, a multistage filter connected with a water outlet of the sand filter, and a reverse osmosis device connected with the multistage filter by a high pressure pump; the reverse osmosis device is connected with a faucet for fresh water to flow out by a pressure regulating valve, and is further connected with a waste water discharging device for waste water to discharge by a water pipe. During use, the seawater enters the sand filter by being lifted and pressurized by the water supply pump, enters the multistage filter for filtration after big suspended matter, fine sand and small stone, diatom, and rust are removed by the sand filter, then enters a first reverse osmosis filter element and a second reverse osmosis filter element by being pressurized by the high pressure pump, and the pressure is adjusted by the pressure regulating valve after the filtration is completed, the fresh water flows out from the faucet, the waste water is discharged by the waste water discharging device, the desalting rate is high, and the filtration effect is good.

Description

technical field [0001] The invention relates to a seawater desalination device, in particular to a high-efficiency reverse osmosis seawater desalination device. Background technique [0002] With the continuous increase of the earth's population, the current fresh water resources are getting less and less, and the fresh water resources will face severe challenges in the future. As we all know, the earth is not short of water. If seawater resources can be used to desalinate seawater, it will effectively solve the problem of shortage of freshwater resources. [0003] At present, there are more than 20 existing seawater desalination technologies. Distillation, reverse osmosis, freezing and electrodialysis are commonly used seawater desalination technologies. Reverse osmosis is characterized by simple equipment, easy maintenance and modularization of equipment. The advantages of the technology quickly occupied the market, and gradually replaced the distillation method as the mo...

Problems solved by technology

However, although the seawater desalination device using the reverse osmosis method in the prior art plays the role of desalinating seawater, it still has the problems of low desalination rate and poor filtering effect in actual use.
