Domestic reverse osmosis membrane seawater desalination device

Abstract

The invention discloses a domestic reverse osmosis membrane seawater desalination device, which comprises a device main body and a freshwater storage tank, wherein the inside of the device main body is divided into a pressurization cavity, a rough filtration cavity, a water pump cavity, a water collecting cavity and an equipment cavity; a pressurization pump is arranged in the pressurization cavity; a pressurization pipe is communicated onto the pressurization pump; a water inlet is formed in the upper surface of the water collecting cavity; a water pump is arranged in the water pump cavity; awater inlet pipe and a water outlet pipe are communicated onto the water pump; a micro-filtration membrane, a nanofiltration membrane and a quartz sand filtering layer are sequentially arranged in the rough filtration cavity from left to right; a water outlet is formed in the lower surface of the rough filtration cavity; the lower surface of the water outlet is communicated with a first water pipe; one end of the first water pipe is communicated with a first filter. The domestic reverse osmosis membrane seawater desalination device has the advantages that the structure is ingenious; the structure is compact; the specification of the device main body is small; the domestic reverse osmosis membrane seawater desalination device is suitable for being used by residents at seaside; the desalination efficiency is high; the speed is high; meanwhile, the energy is saved; the environment is protected; no pollution exists; the domestic reverse osmosis membrane seawater desalination device is convenient for emergency use when a concentrated water supply system has a fault.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a household reverse osmosis membrane seawater desalination device. Background technique [0002] Seawater desalination is the use of seawater desalination to produce fresh water. It is an open-source incremental technology to realize the utilization of water resources. It can increase the total amount of fresh water and is not affected by time, space and climate. It can ensure a stable water supply for coastal residents and industrial boilers. The seawater desalination methods include seawater freezing method, electrodialysis method, distillation method, reverse osmosis method, and ammonium carbonate ion exchange method. At present, the application of reverse osmosis membrane method and distillation method is the mainstream in the market. [0003] The distillation method requires a long period of time, high temperature, and difficult operation. The reverse osmosis m...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that in the prior art, the time period of desalination of seawater by distillation is long, the temperature is high, and the operation is difficult. The reverse osmosis membrane method is relatively short in cycle, does not need to purchase a heating device, and is less difficult to operate. However, the device occupies a large area and is not suitable for home use. A household reverse osmosis membrane seawater desalination device is proposed
