る石炭ガスの脱硫装置。 An absorption tower and a regeneration tower with a moving bed or a fixed bed are used, and the gas containing SO 2 obtained by reacting the absorbent with oxygen in the regeneration tower is guided to the sulfur recovery device through the regeneration gas outlet pipe. In the coal gas desulfurization apparatus having the above structure, a recycle pipe is provided for taking out the gas containing SO 2 diffused from the regeneration tower from the middle of the regeneration gas outlet pipe and recycling it to the regeneration tower, and passing the gas through the recycle pipe. A coal gas desulfurization device comprising a control valve that controls the amount of gas to the sulfur recovery device so that the SO 2 concentration in the recycled gas is at a predetermined concentration.
