Abstract

The invention relates to a device for removing hydrogen sulfide in gas by using a gas delivery pipeline, which comprises a gas delivery pipeline, wherein the gas delivery pipeline is basically horizontal, the diameter of the gas delivery pipeline is greater than or equal to 0.3m, the length-to-diameter ratio is greater than or equal to 10, and the gas flow rate in the gas delivery pipeline is 3-10 m / s; a liquid outlet is arranged on the gas delivery pipeline; in the gas delivery direction, the tail end of the gas delivery pipeline is provided with a gas outlet; and in the gas delivery direction, a plurality of atomizing nozzles for jetting a desulfurization liquid or desulfurization slurry are sequentially arranged in the gas delivery pipeline. In the device provided by the invention, the gas delivery pipeline is used as the location for desulfurizing H2S. Compared with the desulfurization tower or other desulfurization reactors in the prior art, the invention does not need to additionally construct any desulfurizing unit, thereby effectively lowering 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 device for removing hydrogen sulfide in gas 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 Purification Sy...
