Imitated electronic scale type small seawater demineralizer in deep sea

Abstract

The invention provides an imitated electronic scale type small seawater demineralizer in a deep sea. The seawater demineralizer is provided with an imitated electronic scale structure comprising an imitated electronic scale type pretreatment filter drum, an upper beam box, an upright column box, a bottom box body, a swing booster cylinder, a reverse osmosis semi-permeable membrane assembly barrel,an ozone sterilizer, a water storage box and an ultrasonic cleaner connecting pipe. The overall structure is placed in the position which is 30 meters deep below the seawater; under the pressure action of the seawater in the position, the seawater enters the pretreatment filter drum, and the pretreated water enters the swing booster cylinder; meanwhile, under the surge of the seawater, the swingbooster cylinder is driven to rotate to output pressure; after the seawater is pressurized, the seawater enters the reverse osmosis semi-permeable membrane assembly barrel, and under the action of thepressure output by the swing booster cylinder, the reverse osmosis semi-permeable membrane assembly barrel generates reverse osmosis demineralization of the seawater and outputs fresh water; then, the fresh water enters the ozone sterilizer and the water storage box, and the water storage box is driven to output the fresh water; and the ultrasonic cleaner connecting pipe is used for ultrasonically cleaning the reverse osmosis semi-permeable membrane assembly barrel.

Description

[0001] Technical field: It belongs to the technical field of ocean development and seawater desalination. Background technique: [0002] The development and utilization of seawater desalination are hot spots in recent years, and it is one of the green water sources. [0003] The seawater desalinator converts seawater into fresh water and merges it into domestic water, which is ecological and environmentally friendly. [0004] Seawater desalination methods mainly include: distillation, electrodialysis and reverse osmosis, among which: distillation is mainly used in large-scale seawater desalination and places with abundant energy; electrodialysis is to use ion exchange membranes under the action of an electric field to separate Anion and cation, so as to reduce the salt concentration in the fresh water chamber and obtain fresh water as a membrane separation technology, but there are shortcomings such as strict water quality requirements and the need for pretreatment of raw wate...

[0004] Seawater desalination methods mainly include: distillation, electrodialysis and reverse osmosis, among which: distillation is mainly used in large-scale seawater desalination and places with abundant energy; electrodialysis is to use ion exchange membranes under the action of an electric field to separate Anion and cation, so as to reduce the salt concentration in the fresh water chamber and obtain fresh water as a membrane separation technology, but there are shortcomings such as strict water quality requirements and the need for pretreatment of raw water, and poor adaptability; reverse osmosis method, using reverse osmosis half Permeable membrane desalination seawater has a high desalination rate, so it is widely used in seawater desalination, but there are: sediment, particles, bacteria, algae and other microorganisms in seawater, which are easy to stick to the filter screen and reverse osmosis semi-permeable membrane. Frequent cleaning is required, and a high-pressure booster pump is required to pressurize it to work. It has poor adaptability and is not suitable for small and medium-sized seawater desalination; for this reason, this patent proposes a method, a small and medium-sized deep-sea desalination device imitating the ground scale: in the pretreatment The module and the reverse osmosis semi-permeable membrane module are connected with a vibration system and an ultrasonic descaling device to carry out ultrasonic self-cleaning of dirt, and use the pressure of deep sea water and the output pressure of the swing pressurized cylinder to perform reverse osmosis desalination, realizing the miniaturization of seawater desalination. Flexible, water supply to sea islands and sea facilities far away from land, strong applicability, convenient life, energy saving
