Evaporation device

The invention discloses an evaporation device. The evaporation device comprises a buffer tank, a first basket filter, a heating chamber, an evaporating chamber, a vapor-liquid separator, a vapor compressor, a charging pump, a discharging circulating dual-purpose pump, a vapor pump and a feed pipe, wherein a vapor outlet of the evaporating chamber is connected with the vapor-liquid separator; the vapor-liquid separator is connected with an inlet of the vapor compressor; the vapor compressor is connected with the vapor pump; and the outlet of the vapor compressor is connected with the heating chamber. After the vapor compressor raises the temperature of secondary vapor in the evaporating chamber, the secondary vapor is returned to the heating chamber and used as a heat source of the heating chamber. By compressing the secondary vapor generated during evaporation, the vapor pump raises the temperature and pressure of the secondary vapor, and the secondary vapor is used as the heat source of equipment again, so t
