<p>PURPOSE:To absorb difference in pressure between the inside and outside of a washing tower for keeping the amount of liquid in a circulating water tank constant by providing a water sealing part between the overflow nozzle and the overflow pipe of a vapor-liquid contact type washing tower. CONSTITUTION:In a washing tower in which gas is washed by vapor-liquid contact method, an U-shaped washing sealing part 6 is provided between an overflow nozzle 3, overflow pipe 4, and a syphon cut 5. Thus, when the inside pressure of the tower is higher than the atmospheric pressure, the liquid level of the water sealing part 6 becomes lower on a circulating water tank 2 side than on the connection side of the overflow pipe 4 by as much as difference in pressure, whereas, when the inside pressure of the tower is lower than the atmospheric pressure, the liquid level becomes higher on the circulating water tank 2 side than on the connection side of the overflow pipe 4 by as much as difference in pressure. Since the water sealing part 6 absorbs the pressure difference in this way, the amount of liquid in the circulating water tank 2 can be kept constant without being affected by the atmospheric pressure.</p> |
