Part of the steam generated by the first evaporation chamber 7 enters the first cooler 35 through the first steam conveying pipe 19 to be cooled and condensed into liquid state and flows back to the liquid storage tank 42, the other part of the steam enters the third row of pipe heat exchangers in the second heating chamber 21 through the second steam conveying pipe 20 to heat the wastewater in the second heating chamber 21, and the used steam is conveyed to the second cooler 44 through the third steam conveying pipe 32 to be cooled and condensed into liquid state and flows back to the liquid storage tank 42. Wherein the second evaporation chamber 24 keeps the vacuum degree at 0.03-0.08Mpa under the action of the first vacuum pump 39, so that the heated waste water in the second heating chamber 21 is sprayed into the second evaporation chamber 24 through the second discharge port 22 and the second feed port 23, the gasification temperature of the water phase is reduced because the second evaporation chamber 24 is in a negative pressure state, wherein the temperature in the second evaporation chamber 24 is kept at 60-70 ℃, and the steam generated in the second evaporation chamber 24 enters the first cooler 35 from the first steam conveying pipe 19 to be cooled and condensed into a liquid state and flows back to the liquid storage tank 42. When the liquid water stored in the reservoir 42 is cooled to room temperature, it is discharged from the purified water discharge port 43, and the treated purified water can be used for heating in a boiler, or cleaning articles, etc.
The above description is only for the preferred embodiment of the present invention, and should not be construed as limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
