Heat exchanger

Abstract

A heat exchanger comprises a heat exchange container that conducts heat exchange on an inside, a spray nozzle that sprays liquid to be heat-exchanged into the heat exchange container, an injection nozzle that injects gas to mist of the sprayed liquid to be heat-exchanged, and a discharge outlet located on an upstream side of the injected gas to discharge the liquid to be heat-exchanged.

1 . A heat exchanger comprising:
 a heat exchange container that conducts heat exchange on an inside;   a spray port that sprays liquid to be heat-exchanged into the heat exchange container;   an injection port that injects gas to the sprayed liquid to be heat-exchanged; and   a discharge outlet located on an upstream side of the injected gas to discharge the liquid to be heat-exchanged.   
     
     
         2 . The heat exchanger according to  claim 1 , further comprising:
 a heater that heats the heat exchange container to make an inside of the heat exchange container into a heating space to heat the sprayed liquid to be heat-exchanged.   
     
     
         3 . The heat exchanger according to  claim 2 , wherein
 the gas injected from the injection port is a swirl flow in a form of a helix that comes into contact with an inner surface of the heat exchange container while having an orientation reverse to a spray direction of the liquid to be heat-exchanged.   
     
     
         4 . The heat exchanger according to  claim 2 , wherein
 the gas injected from the injection port is heated gas.   
     
     
         5 . The heat exchanger according to  claim 1 , wherein
 the heat exchange container is made of metal,   the inner surface of the heat exchange container is covered with a detachable attached liner made of resin.   
     
     
         6 . The heat exchanger according to  claim 1 , further comprising:
 a heat exchange part comprising a mesh-patterned heat transfer tube having one side facing the spray port and the other side facing the injection port.   
     
     
         7 . A separation system having the heat exchanger according to  claim 1 , further comprising:
 a steam separator connected to the discharge outlet of the heat exchanger, wherein   the heat exchanger generates steam of the liquid to be heat-exchanged, and   the steam separator separates the steam discharged from the discharge outlet of the heat exchanger into a steam component and concentrated liquid.   
     
     
         8 . An aerosol formation system having the heat exchanger according to  claim 2  to form aerosol of first liquid of which vapor pressure is relatively high and second liquid of which vapor pressure is relatively low, comprising:
 a flow tube connected to the discharge outlet of the heat exchanger; 
 a venturi connected to the flow tube; 
 a supply tube communicating with the venturi; and 
 a storage tank communicating with the supply tube, wherein 
 the heat exchanger sprays the first liquid as the liquid to be heat-exchanged from the spray port so as to be vaporized in the heating space so that a dispersion medium is formed for the aerosol, 
 the storage tank reserves the second liquid, and 
 the venturi flows the dispersion medium discharged from the discharge outlet of the heat exchanger to cause the second liquid supplied from the storage tank through the supply tube to be sprayed and become dispersoid for the aerosol. 
 
     
     
         9 . The aerosol formation system according to  claim 8 , further comprising:
 a venturi heater that heats the venturi.   
     
     
         10 . The aerosol formation system according to  claim 8 , wherein
 the venturi has a first chamber communicating with the flow tube and having an inner diameter being larger than of the flow tube, a constricted part having an inner diameter being smaller than of the first chamber, and a second chamber having an inner diameter being larger than of the constricted part, and   the supply tube communicates with the constricted part.
