Abstract
The invention provides a Stirling heat pump seawater desalination device. A Stirling reversible heat engine is employed as a heat pump. A seawater evaporating tank is arranged at a heat outflow end, and a fresh water condenser is arranged at a heat inflow end. Two wind channels through which the sea water evaporating tank and the fresh water condenser are communicated form an air circulation wind channel, and a Stirling heat pump seawater desalination device which can recycle sea salt is formed. The upper part of the seawater evaporating tank is a seawater evaporation zone. The middle part of the seawater evaporating tank is a seawater and cold and dry air admission zone. The bottom part of the seawater evaporating tank is a sea salt crystallization and precipitation zone. The water and air of the seawater evaporation zone are heated to form humid and hot air. The humid and hot air goes to the fresh water condenser through the humid and hot air flow wind channel and is subjected to condensation to form fresh water and cold and dry air. The cold and dry air goes into the seawater evaporating tank through the cold and dry air flow wind channel and is heated and humidified to form humid and hot air again. Heat is transported back to the heat inflow end from the heat outflow end continuously, and used again. Fresh water is evaporated and salt is crystallized and precipitated. The energy consumption is low and no concentrated seawater is discharged. The salt can be used as chemical materials and the comprehensive utilization rate of seawater resource is raised.
Description
Affiliated technical field
The present invention relates to a kind of sea water desalinating plant, be specially a kind of stirling heat pump sea water desalinating plant.
Background technology
Over the past thousands of years, the mankind thirst for from seawater, obtaining fresh water always, develop multiple desalination technology.The sea water desalination method of once using has distillation method, freezing method, electroosmose process, reverse osmosis method.After 1974, developed country has turned to reverse osmosis method by the research direction of sea water desaltination.Reverse osmosis method advantage simple with its equipment, that be easy to maintenance and EM equipment module dominates the market rapidly, and progressively replacing distillation method becomes most widely used method.Key equipment in reverse osmosis method seawater desalination system is monopolized by offshore company substantially, as reverse osmosis membrane, high-pressure pump, energy recycle device etc.
After reverse osmosis method obtains widespread use, ancient distillation method has also been shone the youth again.New distillation method is to reduce air pressure, suitably heating seawater.In vacuum distilling chamber, the fresh water in seawater can evaporate rapidly in moment, became water vapour.Many such vacuum distilling chambers couple together, and have just formed large-scale desalinator.Present large-scale desalinator in the world, adopts new distillation method mostly.
After new distillation method, the U.S. international Shui Neng company has invented a kind of being referred to as " fast spraying distillation method " sea water desalination method (RSD) recently.This principle with the technology that desalinizes seawater of innovative significance is that seawater is sprayed to hot gas flow, makes the moisture in seawater become rapidly water vapour, and salt becomes solid.This method is neither wasted seawater resources, does not also need the fresh water to obtaining to carry out chemical treatment, can directly drink.
Make a general survey of distillation method technical progress course, which kind of distillation method all must meet three conditions: the one, and thermal source, the 2nd, low-temperature receiver, the 3rd, thermal source is to the water vapour passage of low-temperature receiver.For example natural sea water desaltination, exactly change into heat with solar irradiation on sea, water is heated and is evaporated to water vapour, meets condensation form water and fall back that ground realizes with air-flow climb to altitude.As long as find a kind of heat engine that has thermal source and low-temperature receiver, and thermal source is set to the water vapour passage of low-temperature receiver, it is exactly desirable sea water desalinating plant.
Chinese invention patent Stirling reversible heat engine (200710050949.2) has the heat engine of thermal source and low-temperature receiver just, with its heat outflow end, makes thermal source, and heat flows into end and makes low-temperature receiver, the running of motor drive heat engine.Setting flows into the mobile air channel of damp-heat air of end and flows into end to the mobile air channel of cold dry air of heat outflow end from heat from heat outflow end to heat, and on air channel, installs blower fan additional, forms air circulation air channel.The water of heat outflow end absorbs heat into water vapour, is taken to the heat release of heat inflow end condense into water by air circulation, realizes sea water desaltination.At this, Stirling reversible heat engine is as stirling heat pump.A kind of stirling heat pump water-heater of Chinese invention patent (201210473554.4) has been introduced the theoretical calculation method of stirling heat pump design.
