Background
The carbon black production industry is a high energy consumption industry, and the key for reducing the carbon black production energy consumption is to control the production cost and improve the market competitiveness of enterprises in carbon black production enterprises. The air preheater is one of main heat exchange equipment in the carbon black production industry, preheats air required by production from 100 ℃ to about 800 ℃ through the air preheater, cools carbon black flue gas from 950 ℃ to about 660 ℃, improves the sensible heat value of the air by utilizing the sensible heat of the carbon black flue gas, and reduces the fuel supplement amount required by carbon black production so as to reduce the energy consumption of carbon black production. The outlet of the air preheater is connected with the inlet of the reaction furnace through a hot air pipeline, the thermal expansion coefficients of the reaction furnace and the hot air pipeline are not consistent due to the temperature change of flue gas fluid, expansion joints are required to be arranged at the outlet of the air preheater and the joint of the hot air pipeline and the reaction furnace, and meanwhile, the thermal insulation performance of the expansion joints is poor, so that the temperature drop of the inlet air temperature of the outlet of the air preheater and the inlet air temperature of the reaction furnace occurs.
There is a need for an expansion joint that substantially reduces heat loss while maintaining the existing expansion stresses.
