Abstract

A gas-liquid contact reactor with liquid curtain bed is composed of a slurry pool with slurry inlet and outlet, a desulfurizing tower consisting of a forward-current tower and a counter-current two, whose bottoms have more than one row of nozzles and are communicated with each other, a draught blower connected via valve to the fume outlet of counter-current tower, and a circulating slurry tank communicated via regulating valve and circulating pump to said nozzles.

Description

technical field [0001] The invention belongs to the technical field of wet flue gas desulfurization, and in particular relates to a liquid curtain bed gas-liquid contact reaction device. Background technique [0002] Wet flue gas desulfurization process is a relatively mature and stable process with broad market prospects and engineering application value. However, in the existing wet flue gas desulfurization methods, the main flow modes of the desulfurizer include liquid injection type, spray type, bubbling type, packing type and other liquid phase flow modes. These desulfurization technologies are basically based on gas film control, which has low mass transfer coefficient, large system resistance, low liquid-gas ratio, and small load adjustment range. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a method that can increase the absorption liquid content and gas conten...
