SIMULTANEOUS DRAWING METHOD FOR THE FIRST AND THE SECOND DISTILLED WATER AND ITS REDISTILLATION DEVICE

摘要

PURPOSE:To economize heat sources by producing the 1st distilled water right above a boiling tank in proximity thereto and permitting redistillation by making direct use of the steam heat of that time. CONSTITUTION:The 1st boiling tank 8 is provided in the central part in a distilling tank 1, and a cylindrical tank 16 is provided above the tank 8. A partition wall 17 is provided in the tank 16, and the 1st water cooling tank 5 of an annular pipe body is provided in the place near the inner side in the top cover part of the tank 1 in the upper part of the tank 16. The bottom part of the tank 16 is used as the 2nd boiling tank 18. A water discharge pipe 24 which discharges the incremental water that exceeds a specified water level to the outside of the tank 1 is installed in a part on the side wall of the tank 18 and the 2nd level gage 27 is set at the preceding end thereof. A cooling water tank 30 is provided in the lower part of a water discharge pipe 26, and the cooling water pipe of the 2nd water cooling tank 5 is connected thereto.
