Bionic forklift-type deep sea small and medium-sized seawater desalination apparatus

Abstract

The invention relates to a bionic forklift-type deep sea small and medium-sized seawater desalination apparatus. The seawater desalination apparatus is provided with a bionic forklift structure, and the bionic forklift structure comprises a bionic forklift-type pretreatment filter cylinder, a forklift small-arm structure, a forklift middle-arm structure, a forklift large-arm structure, a bionic forklift body sterilization purifying case, a swing pressure cylinder, a reverse osmosis semi-permeable membrane assembly barrel, an ozone sterilizer, a water storage tank, and a supersonic wave cleanerconnection pipe. An integral structure is placed at a position with a 30-meter depth under seawater, under seawater pressure effect with a 30-meter depth, seawater is introduced into the pretreatmentfilter cylinder, the processed water is introduced into the swing pressure cylinder, under surging of seawater, the rotation of the swing pressure cylinder is driven to output the pressure, after supercharging, the seawater is introduced into the reverse osmosis semi-permeable membrane assembly barrel, reverse osmosis desalination of seawater is carried out in the reverse osmosis semi-permeable membrane assembly barrel under pressure effect output by the swing pressure cylinder, and fresh water is output, then the fresh water is introduced into the ozone sterilizer and the water storage tank,the water storage tank is driven to output the fresh water, and supersonic descaling is carried out on the reverse osmosis semi-permeable membrane assembly barrel by the supersonic wave cleaner connection 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...

[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 small and medium-sized seawater desalinator imitating a forklift type deep sea: in the pretreatment component The vibration system and ultrasonic descaling device are added to the reverse osmosis semi-permeable membrane module to carry out ultrasonic self-cleaning of dirt, and the reverse osmosis desalination is carried out by using the pressure of deep sea water and the output pressure of the swing pressurized cylinder, realizing the miniaturization and flexibility of seawater desalination Water supply for sea islands and sea facilities far away from land, strong applicability, convenient life, and energy saving
