Definitions

  • the present invention relates to internal insulation in containers for liquids which have a lower boiling point than the atmospheric temperature, and where the outside of the containers is exposed to higher temperature than the boiling temperature of the liquid inside the tank.
  • the present invention is based on the fact that conducting of heat through gases (Vapour) is difficult, and according to the invention the insulation consists of a layer of gas (vapour) against the wall of the container, retained by means of a system of pores.
  • lamellae are mounted, preferably perpendicularly to the wall and at a relatively small distance from one another.
  • the lamellae are so formed that the space between the same is split up into a number of individual spaces or pores.
  • the temperature will be above the boiling point of the liquid, and the liquid consequently will be transformed into vapour.
  • the temperature will correspond to the condensation temperature of the vapour, and the temperature gradient will form an almost straight line from wall to liquid.
  • the distance be tween the lamellae i.e. the width of the pores, must be so small that practically no convection currents can occur which, in case would increase the heat transfer from wall to liquid. Convection currents may also be counteracted by placing a filling material in the pores.
  • Precautions must also be taken to prevent a convection current along the surface of the wall. This can be done in the simplest way by securing the lamellae to the wall by means of a layer of adhesive material, which thus closes the wall end of each pore. Groups of inter-communicating pores may, however, also be established.
  • Metal, plastic, paper or a woven material can be used for the lamellae, the thickness of the same being very small in order to reduce the heat transmission through the lamellae proper.
  • the reflecting power of the lamellae proper should be as small as possible, and should therefore have a dark and rough surface.
  • the cross-section of the pores formed between the lamellae may be of any desired shape. They may be circular, square, hexagonal etc., such shape being obtained by correspondingly forming the lamellae.
  • the present method of insulation will have advantages over and above the purely insulating capacity when used in connection with the transport of liquid methane in large containers. If the container is subject to impacts or subsidences there is a risk that the inertia of the liquid can develop dangerous tensions in the container wall. This is avoided by the buffer eflect of the vapour in the pores, as this becomes compressed and thereby warmed up by the entering liquid. To control this penetration, the pores may be provided with constricted portions, or the pore cross-section at the point of penetration may be reduced by covering all the pore openings by a net.
  • Figure l is a vertical cross-sectional View of a section of the insulation
  • Figures 2 and 3 are plan views of two embodiments of the lamellae.
  • Figure 4 is a view of an assembled unit
  • Figure 5 is a sectional view of the insulation mounted on the vertical wall of a container.
  • the wall of the container is indicated at 1, and the lamellae are indicated at 2.
  • the lamellae are corrugated and interconnected in such a way that pores 3 with a circular crosssection are formed between the lamellae.
  • the lamellae are bent to a zig-zag shape so that the pores are of a quadrilateral cross-section.
  • the shape of the cross-section may be varied in several Ways, and may, for example, be hexagonal, whereby the lamellae are interconnected along planes instead of along lines, as in the two embodiments shown.
  • an insulating structure disposed at the inside of said wall and defining pores which extend inwardly from said wall and open toward the interior of the container, said insulating snucture including a series of successive formed lamellae which, between adjacent lamellae, enclose straight, tubular hollow spaces defining said pores.
  • an insulating structure disposed at the inside of said wall and defining pores which extend inwardly from said wall and open toward the interior of the container, said insulating structure including a plurality of units each formed of profiled lamellae which, between adjacent lamellae, enclose straight, tubular hollow spaces defining said pores.
