<p>PURPOSE:To prevent fillers from being carried off with the water being discharged by a method wherein a spacing part provided in a moisture absorbing body having the tiny opening in its inorg. porous structure filled with moisture absorbing fillers is evacuated to reduce the pressure thereof and, when a predetermined amt. of water is collected in a liq. collecting part for discharging, the water is heated so as to be evaporated. CONSTITUTION:A moisture-absorbing body 1 is formed by filling moisture-absorbing fillers such as calcium chloride and lithium chloride into the openings of an inorg. porous structure having tiny openings with an average size of at least 10mu in diameter such as gypsum, cement and calcium silicate. A spacing part 4 is provided on one side or in the interior of the moisture-absorbing body 1 (the figure shows the spacing in the case of one side) and evacuated by a vacuum pump 5 to reduce the pressure thereof. When a predetermined amt. of the water is collected for discharging in a liq. collecting part 7 below the spacing 4, it is sensed by a detector 2 and a detection control circuit part 6 is then activated to energize a heating element 3 so as to heat the water for evaporation. When the aforesaid water is decreased to or below a predetermined amt., the heating element is deenergized to stop the heating and the pressure reduction, whereby the conc. water is recovered by the porous structure 1. This prevents the fillers from being carried off with the water and permits the moisture- absorbing body 1 to be used a long period of time.</p> |
