RENOVATION OF PURIFICATION AND DRAINAGE DEVICE OF SULFUR-RICH GAS PIPELINE
The paper introduces a large amount of flue gas produced in the sintering production process,the flue gas is adsorbed by activated carbon in the adsorption tower in the desulfurization and denitrification process,and the activated carbon is analyzed in the analysis tower to produce the mixed gas rich in SO2,and the mixed gas is transported to the acid production system through the pipeline and fan.During the mixed gas transportation process,the temperature of the flue gas drops,and the transportation of sulfur-rich gas will produce condensate in the pipeline.The condensate water in the pipeline will form dilute acid with SO2 and SO3 in the sulfur-rich gas,which will aggravate the corrosion of the sulfur-rich gas pipeline and the condensate drainage system,reduce the service life of the equipment,and cause acid and gas leakage and other safety accidents,affecting the normal production process.Therefore,the condensate water in the pipeline needs to be drained regularly.This paper describes a transformation scheme to completely solve the problems in the production process.The scheme is simple in structure and easy to use.It makes use of the atmospheric environment and the pressure difference in the sulfur-rich gas pipeline to realize no power drainage.It also avoids the labor intensity,poor working environment and safety and health hazards existing in manual regular drainage,and greatly improves the efficiency and effect of drainage.
