Abstract
The invention discloses a system device for desorbing hydrogen sulfide in a gas phase. The system device comprises a raw material gas inlet, an air inlet, a separator, a double-grade rotation fillingbed absorption-regeneration device, a demister, a barren liquor tank, a rich liquor tank, a settlement separation system and a sulfur recycling system, wherein the raw material gas inlet is connectedwith gas inlet of the separator; the gas outlet of the separator, the demister, the barren liquor tank, the rich liquor tank, the air inlet, a tail gas discharge hole and the settlement separation system are respectively connected with the double-grade rotation filling bed absorption-regeneration device; the upper-layer liquid outlet of the settlement separation system is connected with the liquidinlet of the barren liquor tank; a bypass is arranged between the settlement separation system and the barren liquor tank; the bypass is connected with the liquid inlet of the rich liquor tank through a pipeline; and the lower-layer liquid outlet of the settlement separation system is connected with the sulfur recycling system. As conventional absorption equipment and regeneration equipment are combined into one piece of equipment, industrial energy consumption and industrial floor spaces can be reduced, and due to adoption of stator-rotor devices, the process transfer efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of gas purification. More specifically, it relates to a system device and application for removing hydrogen sulfide in the gas phase. Background technique [0002] No matter in industrial production or industrial tail gas, raw material gas containing hydrogen sulfide is very common, such as natural gas, semi-water gas, coke oven gas, synthesis gas, etc. Sulfur-containing industrial gas will cause equipment corrosion, catalyst poisoning, equipment corrosion, etc., and the emission of sulfur-containing waste gas will also cause serious environmental pollution problems. Containing 0.1% hydrogen sulfide in the atmosphere will cause headaches, dizziness and other symptoms, seriously affecting the normal life safety of residents. With social development and people's increasing requirements for environmental protection, the requirements for desulfurization are also getting higher and higher. There is an urgent n...
