In the design of the body of high-temperature industrial dust removal equipment, the thermal expansion of the steel structure and the elimination of thermal stress must be considered, which is especially important in the design of large industrial dust removal equipment. It can be processed according to the specifications of the steel structure design.
　　Another important issue is insulation. The insulation methods, insulation materials and insulation thickness of industrial dust removal equipment should be determined according to the process conditions, required insulation effect, meteorological conditions and surrounding environment. The insulation design should have countermeasures to prevent rainwater from penetrating. In addition to heat preservation, the ash bucket part often needs to adopt heat tracing measures.
