Abstract

The invention relates to the technical field of seawater desalination, and especially relates to a recondensation apparatus of concentrated seawater. The recondensation apparatus of concentrated seawater comprises a low temperature multiple-effect distillation seawater desalination system, an isolating valve, a seawater booster pump, a conductivity instrument and a flowmeter. The inlet of the isolating valve is connected to a concentrated seawater pump of the low temperature multiple-effect distillation seawater desalination system, the outlet of the isolating valve is connected to the inlet of the concentrated seawater pump through a pipeline; the outlet of the concentrated seawater pump is connected to a spray apparatus of the low temperature multiple-effect distillation seawater desalination through the pipeline; and the conductivity instrument and the flowmeter are respectively connected on the pipeline between the isolating valve and the concentrated seawater pump. The recondensation apparatus of concentrated seawater conveniently makes the concentration of seawater to reach a requirement of a salt chemical enterprise.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a concentrated seawater reconcentration device. Background technique [0002] Concentrated seawater refers to the concentrated part of seawater that is concentrated about twice as much after desalination technology extracts fresh water, and when seawater is used as industrial cooling water (especially in power plants), the salt concentration increases with the gradual volatilization of seawater during the cooling process of seawater circulation. The part of the concentrated water that is discharged after the concentration is about doubled. Due to the particularity of the content of concentrated seawater, discharging it into the water will destroy the ecological balance of the water body. The high salinity of concentrated seawater will increase the salinity of the discharge area, and the renewal rate of seawater in semi-enclosed sea areas is slow, making the distrib...
