High-flow-velocity low-gas-separation desulfurizing tower

Abstract

The invention discloses a high-flow-rate low-gas-separation desulfurization tower, and relates to the technical field of gas desulfurization, the high-flow-rate low-gas-separation desulfurization tower comprises a desulfurization tower body, the top of the desulfurization tower body is fixedly connected with a first exhaust pipe, and the bottom of the desulfurization tower body is fixedly connected with a low-gas-separation adding pipe; an air adding pipe, a slurry circulating pipe, a discharging pipe and a slurry feeding pipe are fixedly connected to the side wall of the desulfurization tower body, one end of the air adding pipe is connected with a Y-shaped pipe, the air adding pipe is sleeved with a control valve, the upper end of the slurry circulating pipe extends into the desulfurization tower body, and the upper end of the slurry circulating pipe is connected with a spraying assembly; the slurry circulating pipe is sleeved with a circulating pump, and a filter screen is fixedly installed at a pipe opening in the lower end of the slurry circulating pipe. According to the desulfurization tower disclosed by the invention, sulfur-containing slurry on the inner wall of the desulfurization tower body is pushed downwards by an arc-shaped scraping plate, so that the relatively viscous sulfur-containing slurry can rapidly descend and enters the slurry absorption tank to react with air in the slurry absorption tank, and the reaction rate is increased.

Description

technical field [0001] The invention relates to the technical field of gas desulfurization, in particular to a high-flow rate low-partition gas desulfurization tower. Background technique [0002] The desulfurization tower is a tower-type equipment for desulfurization of industrial waste gas, and the low-separation gas is the gas from the low-pressure separator, which is mainly the gas dissolved in oil and some light hydrocarbons released at low pressure. The gas needs to be desulfurized before entering the next reaction. [0003] The Chinese utility model patent with the publication number CN210303017U discloses a high-flow rate low-partition gas desulfurization tower, which relates to the field of boiler systems, including a tower body, and a lower water curtain mechanism and an upper water curtain mechanism are fixed inside the tower body. The upper water curtain mechanism is arranged on the top of the lower water curtain mechanism, and the top of the upper water curtain...

AI Technical Summary

Problems solved by technology

[0005] (1) The viscosity of the slurry on the side wall of the desulfurization tower makes it fall slowly, resulting in a decrease in the reaction rate in the desulfurization tower, which may cause the air in the lower part of the desulfurization tower to not fully react with the sulfur-containing slurry, and overflow from the slurry pool, resulting in waste of resources

[0006] (2) The gypsum colloid formed in the slurry tank is easy to block the pipeline, affecting the circulation of the absorbed slurry in the slurry circulation pipeline, which will not only affect the normal reaction, but also cause damage to the equipment
