Anti-corrosion lining of tubular silicon carbide high-temperature heat exchanger

The utility model relates to the field of anti-corrosion materials, in particular to an anti-corrosion lining of a tubular silicon carbide high-temperature heat exchanger, which is characterized by comprising a thermal compensation structure arranged at the end of a heat conduction pipe and a cavity anti-corrosion structure arranged in a cavity. After the heat conduction pipe is cooled and shrunk, the heat conduction pipe is reset under the action of the elastic block, and heat compensation is formed for the heat conduction pipe; an anti-corrosion sealing structure between the heat conduction pipe and the floating block effectively avoids gas leakage; the cavity anti-corrosion structure and the flange anti-corrosion structure effectively protect the interior of the cavity, and the cavity anti-corrosion structure has radial elasticity by means of the framework and the woven mesh. 本实用新型涉及防腐材料领域，具体涉及一种列管式碳化硅高温换热器防腐内衬，其特征在于：包括设置于导热管端部的热补偿结构和设置于腔体内部的腔体防腐结构，由于浮动块之间可相对滑动，当导热管受热沿着轴向延长时，其端部跟随浮动块滑动，当导热管冷却收缩后，在弹性块作用下复位，
