Optimization and transformation of the tower tray in the stripping tower of coal gasification device
This article discusses and argue the problems of large pressure fluctuations in the stripping tray of the flash system of the coal gasification device,large pressure fluctuations in the stripping tower,and the temperature of the preheating water at the bottom of the tower not reaching the design value,resulting in liquid flooding and water carryover.The optimization and transformation of the stripping tower tray were carried out.After the transformation,the pressure drop of the stripping tower was ≤ 15kPa,reducing the pressure fluctuations of the stripping tower.The pressure regulating valve was put into automatic mode,and the temperature of the preheating water at the bottom of the tower reached the design value of 157 ℃.The flash system operated stably,achieving the expected transformation purpose.
