Abstract

The invention belongs to a method for desalinating sea water by using equipment, and relates to a method for desalinating sea water by using silicon carbide ceramic disc type flameproof motor plumb joint equipment. The equipment comprises a sea water pretreatment pool, a low-pressure sucking tube, a low-pressure lifting pump, a water complementing sucking tube, a high-pressure make-up pump, a pipeline tee joint, a reverse osmosis membrane and a weld joint pressure exchange elevator pump; as an improvement, the method comprises operation procedures of assembling a disc II-type flameproof motor and key members, and the pressure exchange principle and the reverse osmosis sea water desalination process are as follows: (I) assembling the disc II-type flameproof motor; (II) connecting a weld joint connector pipeline; (III) assembling the key members; (IV) implementing weld joint pressure exchanger operation procedures; (V) implementing reverse osmosis desalination engineering operation procedures. Due to adoption of a weld joint connection structure, high pressure can be endured, and no leakage can be caused; particularly, due to additional arrangement of the weld joint pressure exchange elevator pump, the structure is compact, the energy conservation effect is remarkable, and the energy consumption for acquiring a unit of fresh water can be reduced by about 30%.

Description

technical field [0001] The invention belongs to a seawater desalination method using equipment, in particular to a seawater desalination method using a silicon carbide ceramic disc-type explosion-proof motor welding head equipment and adding a pressure exchange hoist pump to a reverse osmosis seawater desalination system. Background technique [0002] With the advancement of science and technology, the population is increasing day by day, and people's desire to develop into the ocean is becoming stronger and stronger. Seawater desalination treatment is becoming more and more popular, and the energy consumption cost of seawater desalination has received special attention. Early seawater desalination used distillation, such as multi-stage flash technology, with an energy consumption of 9.0kWh / m3, and was usually only built in areas with low energy prices, such as Middle East oil countries, or areas where waste heat was available. In the 1970s, reverse osmosis seawater desalina...
