Embodiment 1

[0041] A seawater desalination and concentrated seawater concentration integrated system, such as figure 1 As shown, it includes a multi-effect evaporation seawater desalination subsystem 1 , a heat recovery and concentration subsystem 2 , an absorption heat recovery subsystem 3 and a solution regeneration subsystem 4 .

[0042] The multi-effect evaporation seawater desalination subsystem 1 includes a first effect evaporator 11, a second effect evaporator 12, ..., an nth effect evaporator 1n, to separate feed seawater into fresh water and a salt concentration of about 7 % primary concentrated seawater. Different from the conventional multi-effect evaporation system, subsystem 1 does not include a condenser, so in addition to outputting fresh water and primary concentrated seawater, it also outputs steam s3 with a saturation temperature of 38°C–42°C produced by the nth effect evaporator 1n. The heating steam of subsystem 1 comes from two parts: the saturated steam s1 with a te...

Abstract

The invention relates to a sea water desalination and concentrated sea water concentration integrated system and a treatment method. The sea water desalination and concentrated sea water concentrationintegrated system comprises a multiple-effect evaporation sea water desalination subsystem, a regenerative heat concentration subsystem, a regenerative heat absorbing subsystem and a solution regeneration subsystem. According to the system, environment sea water is adopted as a raw material, more-than-0.15MPa steam or more-than-125DEG C hot water is adopted as a drive heat source, a small amountof electric energy is added, and fresh water with the saline concentration being lower than 0.003 percent and the concentrated sea water with the saline concentration being higher than 12 percent canbe produced, so that the fresh water is high-efficiently produced, meanwhile, a high-quality raw material solution is provided for various chemical substances such as salts, and the system has the advantages of high energy utilization ratio, high fresh water recovery rate, slow deposit corrosion, good economical efficiency and the like.

Description

technical field [0001] The invention relates to the field of seawater desalination and concentration, in particular to an integrated system and treatment method for seawater desalination and concentrated seawater concentration. Background technique [0002] Seawater desalination technology extracts freshwater from huge reserves of seawater, which has become an effective way to solve the problem of freshwater shortage. According to the separation mechanism, desalination methods can be divided into two categories: membrane method and thermal distillation method. In the thermal distillation method, the low-temperature multi-effect evaporation technology has attracted attention in recent years due to its advantages such as low working temperature (the maximum temperature of brine is lower than 70°C), slow corrosion and scaling, low power consumption, good performance under variable working conditions, and low operating cost. . [0003] The low-temperature multi-effect evaporat...
