Be applicable to high temperature methanation waste boiler tube sheet entry protective case

The utility model discloses a be applicable to high temperature methanation waste boiler tube sheet entry protective case, a serial communication port, including high temperature resistant stainless steel base member, high temperature resistant stainless steel base member has loudspeaker form entry, has plated the one deck enamel layer on the outer periphery of high temperature resistant stainless steel base member. The utility model has the advantages of as follows: protective case provides rigid support for thermal insulation material, and thermal insulation material twines at the protective case surface, avoids the thermal shock of tube side high temperature medium to the tube sheet, local resistance when horn mouth reduction tube side medium passes through the mouth of pipe, the stainless steel base member that plays supporting role can be able to bear or endure high temperature more than 650 DEG C, surface enamel not only can be high temperature resistant, also has the superior anti hydrogen -type corrosion and the effect of metal powder ization corruption.
