<p>PURPOSE: Provided are a heat recovery type distillation method and apparatus using refrigeration cycle. CONSTITUTION: The method comprises the steps of preheating a vaporization tank(10) using a vacuum boiler(34); purging out a gas in the vaporization tank(10) and a condensing tank(14) and maintaining the vacuum status in the vaporization tank(10) and the condensing tank(14); driving a refrigeration cycle designed to circulate refrigerant through a compressor(40), a refrigerant condensing coil, automatic expansion valve (AEV)(50), a refrigerant vaporizing coil and the compressor(40) in turns so as to heat night soil in the vaporization tank(10) using heat generated from the refrigeration cycle while the refrigerant is condensed in the refrigerant condensing coil; and transferring the vapor generated from the vaporization tank(10) through a connection duct(12) to the condensing tank(14) to convert the vapor into distillation water.</p> |
