Description
Technical field
The present invention relates to sea water desalting equipment, relate in particular to the equipment that a kind of method by distillation makes sea water desaltination.
Background technology
The method that seawater is desalinated has two kinds: a kind of is osmose process, and another kind is distillation method.
At Chinese patent Granted publication number, for 201978517U, Granted publication day, be September 21 in 2011 day, be called in the patent documentation of " a kind of evaporation chamber for evaporation system adopted in brine condensation " and disclose a kind of equipment that can desalinate seawater.Equipment in this patent comprises vacuum vessel, heating chamber and the recycle pump that feed liquid is circulated between vacuum vessel and heating chamber.During use, on vacuum vessel top, gas coagulation units is set, feed liquid is contained in vacuum vessel, recycle pump circulates feed liquid between vacuum vessel and heating chamber, feed liquid is heated in heating chamber, the feed liquid of heat produces Evaporation Phenomenon while getting back in vacuum vessel and forms gas, and gas again becomes liquid under the effect of gas coagulation units.
In Chinese Patent Application No., be 2003101071932, within open day, be June 8 in 2005 day, be called in the patent documentation of " spray heat-exchange type seawater desalination machine " and disclose another kind of sea water desalting equipment.Evaporation equipment in this patent comprises evaporator room and is positioned at the refrigerant condenser of evaporator room, and in use procedure, seawater spraying is to refrigerant condenser, and during refrigerant condensation in condensation condenser, releases heat heat and seawater produced evaporate seawater.Steam flows to and in condensing chamber, is condensed into water.
The heat of above sea water desalting equipment during because of evaporation of seawater all provided by outside, and the heat discharging during vapor condensation can not get recycling completely, therefore has the problem of heat utilization ratio low (efficiency is low).
In order to make heat be recycled utilization, design multiple-effect (multistage) vapo(u)rization system, being about to many over-heat-exchangers is connected in series, first step heat exchanger heats by external heat source, make the feed liquid evaporation in interchanger, the steam that evaporation produces is re-used as the thermal source of next interchanger, steam makes self temperature decline when the feed liquid in next stage interchanger is heated, both be conducive to the condensation of steam, play the effect of heat energy recycling simultaneously, thereby reduced energy consumption and improved vaporization efficiency.The vapor temperature of considering feed liquid evaporation and forming can decline successively, temperature does not reach the vaporization temperature of feed liquid under normal atmosphere, therefore to interchanger at different levels reduce pressure successively (vacuumizing) temperature of the steam that the gasification temperature of feed liquid flows into upper level is matched.Owing to being vacuumized the restriction of difficulty, the progression of multi-effect evaporation system can not be too many.For overcoming above-mentioned deficiency, the patent documentation that be 2005800335343 in China Patent No., name is called " have and distill by reheated steam in the multi-effect evaporation system of chamber of horizontal plate type heat exchanger or the method and apparatus of evaporated salt water or certain fluid " is disclosing a kind of progression and is not belonging to the vapo(u)rization system of restriction.This system is in feed liquid evaporation and before the steam forming enters next stage heat exchanger, the steam that this is had higher than room temperature is heated to the temperature that can make feed liquid gasify under normal pressure, thereby do not need heat exchanger to vacuumize, thereby progression can be designed arbitrarily as required.
Multistage evaporation when the sea water desalting equipment, although the heat of steam has been realized to small portion recovery, still needs constantly to provide and evaporates required heat, and still needs to expend external energy and go steam to carry out condensation.
Energy consumption when reducing condensation, China Patent No. be ZL2010102700217, Shen Qing Publication day are February 16 in 2011 day, in being called the patent documentation of " flash distillation condensation integrated seawater desalinization device ", a kind of sea water desalting equipment is disclosed.Sea water desalting equipment in this patent documentation is by siphonage, the seawater of deep layer (temperature is lower) is air-breathing for to vapor condensation use, thereby does not need outsidely by energy, to remove to make vapor condensation.
Which kind of mode no matter existing sea water desalting equipment take, all can only take the Energy Intensity Reduction of evaporation or the condensation one in the two into account, and the heat discharging in the condensation process medium that is all condensed is taken away, therefore exist the recovery utilization rate of energy low, need constantly from outside, to obtain that heat can make evaporation of seawater, the energy consumption while causing sea water desaltination is large, production cost is high.But the fresh water purity of this gained when although to be also distillation method desalinate seawater the sea water desalting equipment of high distillation method make to be in actual applications used less and the sea water desalting equipment of osmose process uses and to obtain many reason places.
