Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fuel gas, and particularly relates to a high-efficiency fuel gas desulfurization device. BACKGROUND

[0002] The existing fuel gas desulfurization device constitutes a complete system for treating sulfur-containing fuel gas. After the fuel gas is purified by desulfurization, liquid droplets are usually entrained in the flue gas to form mist. In order to remove the liquid droplets in the flue gas, a demister is usually arranged in the flue gas passage. The commonly used demister structure is relatively simple, mainly relying on a single layer of baffle. The baffle changes the flow direction of the flue gas, and uses the inertial effect to make the liquid droplets impact the wall and be removed.

[0003] However, this single-layer baffle demisting method has obvious defects: the demisting efficiency is limited, and it is difficult to completely capture and remove the fine liquid droplets in the flue gas. Therefore, a certain amount of liquid droplets (mist) still remains in the flue gas after the demister treatment, which reduces the overall demisting effect.
