Problems solved by technology

[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 The 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 the seawater, which are easy to stick to the filter screen and reverse osmosis semi-permeable membrane. Frequent cleaning requires a high-pressure booster pump to pressurize to work, which has poor adaptability and is not suitable for small and medium-sized seawater desalination; for this reason, this patent proposes a method, a pumping unit type deep-sea small and medium-sized seawater desalination device: 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

Abstract

The invention relates to a pumping unit-simulated deep-sea small and medium-sized sea water desalination device. The sea water desalination device is provided with a pumping unit-simulated structure and comprises a front triangular support, a rear triangular support, a pretreatment filter cylinder, a swing pressurizing cylinder, a reverse osmosis semi-permeable membrane component barrel, an ozonesterilizer, a water storage tank and an ultrasonic scale remover connecting pipe. The whole structure is placed at a place which is thirty meters deep in sea water; sea water enters the pretreatment filter cylinder under the pressure effect of the sea water of the depth of thirty meters; the preprocessed water enters the swing pressurizing cylinder; simultaneously the swing pressurizing cylinder is driven to rotate to output pressure under the surging of sea water; the pressurized sea water enters the reverse osmosis semi-permeable membrane component barrel; reverse osmosis is carried out by the reverse osmosis semi-permeable membrane component barrel for desalting the sea water and fresh water is output under the effect of the pressure output by the swing pressurizing cylinder; then the fresh water enters the ozone sterilizer and the water storage tank; the water storage tank is driven to output the fresh water, and ultrasonic descaling is carried out on the reverse osmosis semi-permeable membrane component barrel through the ultrasonic scale removing device connecting pipe.

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...
