H3o6peTetme relates to the field of construction, in particular, to the design of high pressure housings with thermal insulation, in the interior of which technological processes take place at high pressures and temperatures.

A device of reinforced concrete casing-high pressure, containing a layer of tenloizol 1ik, made with metal ob / point with thermal compensators of the right: sew form is known. .L1 metal sheath is fastened with anchors passing through a layer of thermal insulation; the anchor is attached to the sheath in the center formed by thermal compensators Fll.

The disadvantages of this device are that the use of solid insulators of blocks requires the device of thermal compensators between them, and the proposed thermal compensators of the shell are difficult to manufacture, moreover, the interface of thermal compensators is due to a wide spread;

In this case, the work undergoes significant deformations, and the gap in the shell at the points of attachment of the anchor does not protect the coolant from being contaminated by thermal insulation material.

The closest technical solution to the invention is a high pressure reservoir comprising a body, a heat insulating layer, a metal facing layer placed on the inside of the body and made of individual sheets, an anchor for attaching the heat insulating and facing layers to the body and corrugated temperature compensators in the facing layer . . Fastening of sheets and thermal insulation material is carried out in the center by a rigid anchor 2..

The disadvantages of such a body are that with thermal expanders of sheets of a frontal weld of a corrugated compensator it works in a complex tension state, the force is steep, it flows through the seam from one

of the sliding element on the other, the lines of force flow are sharply curved and, therefore, simultaneous stresses arise from the axial force, bending and cutting. The seam operation is aided by fluctuations in temperature expansion characteristic of high pressure casing operation. In addition, since each facing sheet is fastened with a separate anchor, and the distance between the sheets is limited.

are limited by the size of the temperature expansion of the sheets themselves and the dimensions of the corrugated compensator, a large number of small-sized sheets is needed, which increases the total number of stitches. Each corrugated compensator is welded on two sides, connecting two adjacent sheets, which increases the

The sheets are directed directly at each other. The complex configuration of corrugated compensators makes installation difficult. thermal insulation.

Due to the use of the inner hermetic shell, the thermal shedding material must have sufficient strength to withstand the internal: orus pressure, and as a consequence, the higher other. -Capacity - increased coefficient of heat- 35 prbvodnosti.

The aim of the invention is to improve the efficiency of thermal insulation and facilitate its installation.

The thermal compensators of the liner layer form hexagons, and the anchors for fastening the blocks are cracked in the center of each block.

FIG. 1 shows a diagonal block; in fig. 2 cut along the fan; in fig. 3 - a general view of the device of a wall of thermal insulation.

The heat insulating layer 1 made of fiber-reinforced high-temperature heat-insulating material is separated by metal nets 2 and attached to a metal facing lyrate 3, which has temperature compensators 4, made in the form of corrugations. On the facing sheets 3 there are holes, covered with filters. Each hexagonal block is fastened at the corners and in the center with anchors 6.

The construction works as follows; .

. Each hexagonal facing sheet 3 with a heat insulating layer with metal grids attached to it forms an assembly unit. Such fully prefabricated units are attached to the inner surface of the high pressure casing and are fastened around the perimeter between each other, for example, by welding. After mounting the blocks on the surface obtained from the cladding sheets, they are formed from thermal compensators.

 hexagons, the centers of which are combined with anchors, fastening obla-; to the inner surface of the high pressure body. When the pressure inside the housing rises by filling the latter with coolant, the coolant will freely penetrate the filters inside the thermal insulation layer, fill the thermal insulation material and equalize the pressure inside the thermal layer of the pressure vessel. When pressure fluctuates in the housing, it will automatically equalize with the pressure in the thermal insulation layer through the filters. The main task of the filters is to prevent particles of the thermal insulation material from entering the interior of the body. When equalizing the pressures of the heat transfer medium in the housing and in the thermal insulation layer,

the heat insulation layer does not interfere with the penetration of the heat transfer medium and pressure equalization in the heat insulating layers. They are the longitudinal reinforcement for the thermal insulating layer, which prevents stratification and screening of thermal insolation under the influence of gravitational force and under the influence of the vibrating screen caused by the uneven movement of the coolant flow. The hexagonal configuration of facing sheets is due to the fact that the perimeter of a regular hexagon is smaller than the perimeter of a square with the same area, which will significantly save time for connecting blocks during installation. In addition, the choice of the shape of a regular hexagon for cladding sheets allows thermal compensator configurations to also be made in the form of a hexagon, which reduces the number of joints by installing the cladding, Tei expansion joints forming in terms of hexagons, have more reliable joints because they join with an angle of 120, rather than 90 °, as in the rectangular version. In such a node, when the body temperature rises, the maximum deformations of the two adjacent sheets are directed not at each other, but at an angle of 1 20 ° to each other, which increases the deformation of the thermal compensator in this place not by 2 times, but only 1.5 times. A high-pressure reinforced concrete body, Lenin has several advantages: the use of facing sheets of a hexagonal configuration significantly reduces the perimeter of the sheet, and this, in turn, reduces the length of the joints between the sheets; the proposed corrugation facilitates the work of the weld at temperature expansion and eliminates the need to make separate special compensators; corrugated hexagons are formed in the structure, each of which is attached in the center by an anchor; temperature compensators in the form of corrugated hexagons have more reliable corrugation junction points, since there is no effort or temperature movement directed to opposite sides; the use of gas-filled thermal insulation allows the use of the most efficient thermal insulation materials. Without paying attention to their strength properties; The use of grids in the heat insulating layer of fibrous materials will increase the reliability and durability of cocktails. Not increasing the coefficient of thermal conductivity; gas filling of the thermal insulation will occur through the filters, which will ensure the rapid distribution of pressure in the thermal insulation and reliably protect the coolant from possible contaminants from, as a rule, the dust material of the thermal insulation; Manufacturing each factory at the factory will minimize the time and cost involved in installation. l and 3 brie n and 1, High pressure tank, including body, heat insulating layer, Metal facing layer, placed on the inside of the body and made of separate sheets, anchor for fixing the heat insulating and facing layer to the body and corrugated thermal compensators in the cladding layer, characterized in that, in order to increase the thermal efficiency of the tank and facilitate its installation, holes are made in the cladding layer, into which filters are inserted, and in the heat-insulating layer metal grids are placed parallel to each other and the planes of the heat insulating layer, and dividing the heat insulating layer along the thickness into sections; The tank according to claim 1, characterized in that the anchors for fastening the blocks are placed in the center of each block.
