A high-flow rate low-separation gas desulfurization tower

Abstract

The invention discloses a high-velocity low-partition gas desulfurization tower, which relates to the technical field of gas desulfurization. A high-flow-rate low-partition gas desulfurization tower includes a desulfurization tower body. The top of the desulfurization tower body is fixedly connected with a first exhaust pipe for desulfurization. The bottom of the tower body is fixedly connected with a low-separation gas feeding pipe, and the side wall of the desulfurization tower body is fixedly connected with an air feeding pipe, a slurry circulation pipe, a discharge pipe and a slurry feeding pipe, and one end of the air feeding pipe is connected with a Y-shaped pipe , the air supply pipe is provided with a control valve, the upper end of the slurry circulation pipe extends to the inside of the desulfurization tower body, and the upper end of the slurry circulation pipe is connected with a spray assembly, the slurry circulation pipe is provided with a circulation pump, and the slurry circulation pipe A filter screen is fixedly installed at the nozzle of the lower end. In the present invention, the arc-shaped scraper pushes the sulfur-containing slurry on the inner wall of the desulfurization tower downward, so that the relatively viscous sulfur-containing slurry can drop rapidly, enter the absorption slurry pool and react with the air therein, and the reaction rate is improved.

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
