Description

Regional flexible insulation construction of low temperature fluid reservoir saddle

Technical Field

The application relates to a flexible heat preservation structure for a saddle area of a low-temperature liquid tank.

Background

The marine ultra-low temperature cargo tank field is in the saddle region, because the saddle itself is low temperature laminated wood, and there is three shrinkage than inconsistent with jar body low temperature steel and heat preservation, leads to the contact layering easily, because jar body low temperature shrink accumulates the rising crack in saddle department between the heated board simultaneously. Handling and post-maintenance at the saddle is therefore of great importance.

The heat preservation structure that the regional heat preservation of present low temperature liquefied gas cylinder saddle adopted includes two kinds:

1) the whole body adopts a plate type heat preservation mode, and the saddle area is bonded with the heat preservation plate through low-temperature glue. The advantage is that the construction is simple, does not receive the influence of environment humiture, and is visual comparatively pleasing to the eye. However, the low-temperature glue is prepared by two components in proportion, so that the preparation and mixing are not uniform sometimes, and the property of the glue is influenced; meanwhile, the glue is smeared by workers with different thicknesses and even cavities, so that low-temperature cold leakage is serious. The outer structure of the heat preservation layer is a rigid outer protection layer made of galvanized steel plates, stainless steel plates and the like, and is directly sealed with laminated wood by sealant, so that the toughness and the anti-shrinkage performance are poor.

2) The whole body is insulated by adopting on-site foaming such as spraying, and the saddle area is sprayed on laminated wood by spraying polyurethane. The method has the advantages that the construction is rapid, the defects are that the construction is influenced by the temperature and the humidity of the environment, the forming is poor, and meanwhile, the bonding with laminated wood is only carried out by spraying and bonding of polyurethane, so that the reliability is poor.
