Background technology
Sea water desaltination also claims that seawaterization is light, sea water desalinization, refers to the unnecessary salinity in water and mineral substance are removed to the operation that obtains fresh water.Sea water desaltination is mainly in order to supply drinking water and agricultural water, and edible salt also can be produced as byproduct sometimes.Sea water desaltination is very popular in Middle East, on some island and ship, is also used.Sea water desaltination needs large energy, so not high in not rich national economy benefit.
Announce No. 095140125 " absorption cold freezes sea water desalination method " new patent case (notification number: I303995), it utilizes absorption refrigerating machine is freezing instrument, by the refrigerant pipe of the vaporizer of flowing through, be back to sea water desaltination groove, the temperature of seawater (or salt solution) is down to below zero pour, fresh water (or claiming pure water) generation ice crystal in seawater is solidified, separate fresh water and salinity in seawater (or salt solution).
Be positioned at the refrigerant pipe of sea water desaltination groove, its refrigerant temperature is lower than seawater zero pour, and produces ice crystal in the surface in contact of seawater and refrigerant pipe and solidify, and ice crystal is fresh water, or is called pure water, reaches the object that separates seawater salinity.Constantly continuing after accumulation ice crystal, the strong brine of groove inner bottom part, can discharge by the mouth of pipe.
Complete after strong brine discharge program, conversion second tributary of refrigerant pipe, drainage refrigerant is to the hot copulatory organ of condenser of absorption refrigerating machine, and the heat that absorptive condenser gives off, accelerates to melt the ice crystal in sea water desaltination groove.Now, refrigerator evaporator can be introduced in the freezing tributary of the second sea water desaltination groove, carry out the second groove subzero fractionation program.
Known via above narration, the absorption cold of front case freezes when sea water desalination method is actual to be used still has following shortcoming to produce:
One. front case is difficult for for the temperature control of sea-water ice crystallization and freezing, if slightly error of the temperature that ice crystal solidifies, the ice crystal that seawater and refrigerant pipe surface in contact produce solidifies and still may contain salt, and it is wanted to obtain the complete pure water without salinity and still has any problem.
Two. the absorption cold of front case freezes sea water desalination method, makes sea-water ice crystallization and freezing in refrigerant pipe surface, and the surface of this refrigerant pipe provides the scope (surface-area) of sea-water ice crystallization and freezing limited, and the sea water desaltination output of this front case is very rare.
Three. the refrigerant pipe surface of front case is except solidifying for ice crystal, more can absorptive condenser the heat of discharge, ice crystal is melted in acceleration, and the process that this ice crystal solidifies and ice crystal melts is all carried out in refrigerant pipe, make the enforcement scope of operation of sea water desaltination interim between tediously long, inefficient problem.
Four. the absorption cold of front case freezes sea water desalination method, great factory building need be set can carry out, because of sea water desaltination output rareness and the activity duration of single refrigerant pipe tediously long, for the sea water desaltination output that makes the same time increases, dealer must bet huge fund can implement this front case, and its utmost point does not meet industry applications.
Above-mentioned shortcoming all manifests all not convenient property that open front case derives in the use, causes sea water desaltination dealer that wish is set not high, therefore, how to overcome above-mentioned problem, in fact for current industry is needed the target of making great efforts to reach badly.
