Abstract

The invention relates to an oil furnace flue gas purification compound tower integrating dust removal, smoke abatement and desulphurization, and belongs to the technical field of oil furnace flue gas purification. The tower comprises a casing, a flue gas inlet formed at the lower part of the casing, a slurry discharge port formed at the bottom of the casing, a slurry discharge pump connected with the slurry discharge port, multistage spray pipes arranged at the upper part of the flue gas inlet up and down, circulating pumps arranged in circulating pipes which are communicated with the multistage spray pipes, a demister arranged above the spray pipes, and a flue gas outlet formed at the top of the casing. The tower is characterized by further comprising an umbrella-shaped device arranged under the lowest stage of spray pipes, and one layer of pore plate arranged between the topmost stage of spray pipes and the next topmost stage of spray pipes. The tower can modify the distribution of a gas field inside, can improve the desulphurization efficiency, and can reduce the liquid-gas ratio so as to reduce the cost.

Description

technical field [0001] The invention belongs to the technical field of oil furnace flue gas purification, and in particular relates to the structural design of an oil furnace flue gas purification composite tower integrating dust removal, smoke elimination and desulfurization. Background technique [0002] Oil furnaces generally use diesel fuel, but due to economic factors, the price of diesel oil is high and the supply is tight. In order to reduce costs, most companies use relatively cheap heavy oil with sufficient supply; since the sulfur content of heavy oil is generally around 3%, There is a large amount of SO in the exhaust gas of boiler fuel oil 2 , have considerable contributions to air pollution and even the formation of acid rain. [0003] Heavy oil is the last remaining low volatile product of the petroleum refining process. Therefore, most or all of the trace elements of high-boiling high-molecular hydrocarbons (paraffin, asphalt, aromatics, etc.) contained in c...
