Method for separating fresh water by using disc type trapezoidal magneto cerium oxide thread generator

Abstract

The invention belongs to a fresh water separation method in seawater by using a generator. A method for separating fresh water by using disc type trapezoidal magneto cerium oxide thread generator comprises a seawater pretreatment tank, a pretreated seawater suction pipe, a start suction pipe, a high-pressure start pump, a pipeline tee joint, a reverse osmosis membrane and a thread pressure exchange supercharger pump; and as improvement, the steps of disc type trapezoidal magneto assembly, thread joint pipeline connection and key component assembly are as follows: (I) the assembly of the disc type trapezoidal magneto; (II) the thread joint pipeline connection: (1) supercharging internal thread joint connection; (2) like the supercharging internal thread joint connection way, a pressure relief thread joint, a suction port thread joint and a pressure accumulation thread joint are in threaded connection with the pipelines on the two sides of the position respectively; and (III) the key component assembly: (1) mounting of a front cover shaft spacer bush; and (2) mounting of last-level bearing outer ring. According to the invention, by adopting a thread connection structure, the maintenance is convenient, and the disassembly is fast.

Description

technical field [0001] The invention belongs to a method for separating fresh water from seawater by using a generator, and in particular relates to a method for separating fresh water by using a disc-type trapezoidal magneto cerium oxide thread generator and adding a pressure exchange hoist pump in 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 ...
