Abstract
Description
Claims (2)
- The heating of an aluminum oxide high pressure stripping workshop section and the insulation dissolving-out method, its uses steam to heat ore pulp step by step in inside is provided with the autoclave (1) of heating tube bundle, the insulation stripping of ore pulp is carried out in the insulation remaining tank (2) of no heating tube bundle, it is characterized in that: it joins 80%~85% of required live steam total amount in preceding 1~5 grade of autoclave (1), allow the stripping reaction take place in advance, make ore pulp enter insulation remaining tank (2) before, in preceding 1~5 grade of autoclave (1), just reach the stripping temperature.
- 2. the heating of aluminum oxide high pressure stripping according to claim 1 workshop section and insulation dissolving-out method, it is characterized in that: it reduces 30%~40% with the heating tube bundle quantity in last 1~3 grade of autoclave (1) on original basis, replenishing after slurry temperature reduces when allowing last 1~3 grade of autoclave (1) as just stripping reaction generation.
