introduction of vacuum storage tank (middle) - doer equipment
insulation system:
the equipment adopts vacuum powder insulation. the insulation material used is expanded perlite (pearlite). its performance requirements are as follows:
serial number | indicator name | index |
1 | bulk density | 40~60kg/m³ |
2 | granularity | 0.1mm~0.2mm不少于90% |
3 | thermal conductivity | ＜0.026w/m·k·s（常压，温度310~77k） |
4 | moisture content | ＜0.1%（质量比） |
5 | unexpanded rate | ≤1% |
6 | ph value | 6.5～7.5 |
▲ in order to effectively improve the thermal insulation performance, a light blocking agent with good chemical stability and no explosion in oxygen enriched environment is added to the pearlescent sand.
▲ in order to avoid the pearlescent sand from moisture (high moisture content), special tooling is made for the storage, transportation and filling of pearlescent sand.
▲ when filling pearlescent sand, strictly control its filling density and try to be solid (≥ 1.8 times the interlayer volume) to prevent settlement.
▲ the liquid pipeline from the inner tank is provided with a liquid seal (gas seal liquid) structure.
▲ the supporting material of the inner tank adopts epoxy glass cloth rod with small thermal conductivity, strong pressure bearing capacity, low air release rate and strong low-temperature impact resistance.
