SUPERJET BUBBLING GAS-LIQUID CONTACT METHOD AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a gas liquid contact method of the gas-liquid contact efficiency higher than those heretofore available and also provide a device for carrying out the method. ;SOLUTION: The superjet bubbling reactor(SJBR) 50 is provided with a gas cooling section 52, a space 62, a superjet bubbling pipe 66 hanging down from a deck plate 64 and a gas-liquid separation chamber 58 on the deck plate. When the STBR is applied for the flue gas desulfurization, flue gas cooled in the gas cooling section is flowed into the space together with an absorption reactive liquid, and the absorption reactive liquid is separated therefrom. Therefore, the adhesion of solids on the deck plate or the like to increase the pressure loss as heretofore generated is not generated, nor the solid removing work is required. The absorption reactive liquid is stored in the jet bubbling pipe by the pressure balance of flue gas, and the flue gas is introduced from a lower opening at the siginificantly high speed in the pipe. The gas-liquid contact efficiency is improved by the arrangement. The accompanying reactive liquid is separated from the purified flue gas from the upper end of the pipe by a gas-liquid separation chamber.;COPYRIGHT: (C)1998,JPO
