Abstract

A desulfurization and regeneration device for removing H2S by using a gas delivery pipeline according to the present invention includes: a gas delivery pipeline, the gas delivery pipeline is basically arranged horizontally, the diameter of the gas delivery pipeline is greater than or equal to 0.3m, and the major diameter is Ratio is greater than or equal to 10, a liquid outlet is provided on the gas delivery pipeline; a gas outlet is provided at the end of the gas delivery pipeline; a regeneration tank is provided below the gas delivery pipeline, and a regeneration tank is arranged at the bottom of the gas delivery pipeline An aeration device is arranged in the middle; in the gas delivery pipeline, a plurality of atomizing nozzles for spraying desulfurization liquid or desulfurization slurry are sequentially arranged along the gas delivery direction. The device for removing H2S in the gas by using the gas delivery pipeline of the present invention uses the gas delivery pipeline of the gas as the place for desulfurization of H2S. Compared with the desulfurization tower or other desulfurization reactors in the prior art, no additional desulfurization is required The device effectively reduces the construction cost of the equipment.

Description

technical field [0001] The invention belongs to the field of gas purification, and in particular relates to a desulfurization and regeneration device for removing H2S by using a gas delivery pipeline. Background technique [0002] h 2 S is a toxic, harmful and highly corrosive impurity widely present in coke oven gas, water gas, natural gas, biogas, crude synthesis gas, etc. 2 When the above gas of S is used as fuel, the H in it 2 S and its combustion product SO 2 All of them are toxic substances, which will cause environmental pollution. Therefore, the above-mentioned gases must be desulfurized and purified before being used as fuel. [0003] In order to ensure the effect of desulfurization, the prior art is used to remove H 2 The desulfurization device of S is usually equipped with packing or other desulfurization components, such as in the Chinese scientific and technological literature "Structure Improvement and Application of Desulfurization Tower in Crude Syngas Pu...
