The invention discloses a method for lining a sulfur-to-acid converter with a thermal insulation material. The method comprises the steps of manufacturing of a thermal insulation framework, bundling and fixing treatment, primary reinforcement treatment, welding treatment, bonding reinforcement treatment and secondary reinforcement treatment, and the sulfur-to-acid converter lined with the thermalinsulation material is obtained. According to the technical scheme of lining the sulfur-to-acid converter with the thermal insulation material, the loss of the temperature in the converter can be effectively and fundamentally restrained, the continuous constant time of the internal temperature of the sulfur-to-acid converter in a shutdown state can be effectively prolonged to 48 hours, the duration of the thermal insulation effect is prolonged by about 40 hours compared with the duration of the thermal insulation effect of an existing converter, and the double protection is achieved by combining the thermal insulation
