Description

The utility model relates to the thermal insulation of tanks, cisterns, tanks, tankers and equipment for the storage, transportation and processing of liquids, for example, crude oil, fuel oil - reserve fuel, kerosene, gasoline, engine oil and other oil products. The utility model can be used when modifying the thermal insulation design of existing and planned reservoirs, tanks, tanks, and tankers.

Known capacity for storage and transportation of flammable liquids, which contains a housing with a heat-insulating layer made of hollow glass microspheres from fly ash of thermal power plants with a binder (see the description of the invention to the copyright certificate SU 1724524 A1, IPC-5 B65D 88/74, 90 / 06, publication 04/07/1992). This thermal insulation has improved quality due to the elimination of the emergence of microspheres in a liquid binder.

The disadvantages of this invention is the location of the insulation on the outside of the tank, which reduces performance, does not protect the inner surface of the tank from corrosion.

Known capacity for storing and transporting liquids, which contains a housing with a heat-insulating layer located inside the housing (see the description of the utility model to the patent of the Russian Federation No. 42874 U1, IPC F16L 59/00, publication December 20, 2004).

Disadvantages: this technical device is complex, time-consuming, due to the installation of additional metal formwork inside the tank, the installation of electromagnets that keep the microspheres from floating up by a magnetic field.

The technical task of the proposed utility model is the creation of a heat-insulating structure that provides increased adhesion and corrosion resistance due to the combination of standard primers used in the manufacture of tanks, tanks, containers, tankers and equipment for liquids and ultra-thin heat-insulating coatings that prevent heat loss and condensation.

The essence of the utility model is as follows.

A thermal insulation device for reservoirs, tanks, containers, tankers and equipment, containing a thermal barrier coating made on the inner and outer steel surface of the tank, tank, tank, tanker, equipment and consisting of a primer and thermal insulation material made in the form of layers of acrylic binder, catalyst composition and clamps and ceramic microspheres with discharged air, the thickness of which is 1.5-3 mm.

The essence of the proposed solution is illustrated by drawings.

In FIG. 1 - shows the contour of the tank or tank.

In FIG. 2 - a section is given of the wall of a tank or tank with applied heat-insulating coatings.

In FIG. 1 is indicated: 1 - the contour of the tank or tank, A - the side wall of the tank or tank.

In FIG. 2 is indicated: 1 - part of the contour of the tank or tank, 2 - thermal insulation coating on the outside of the tank or tank, 3 - thermal insulation coating on the inside of the tank or tank.

The material is applied in layers to the outer and inner surfaces of the tank or tank (Fig. 1). Material properties make it possible to cover structural elements of a tank or tank with a complex geometry 1 with a uniform layer (Fig. 2). When applying a layer of heat-insulating material 3 (Fig. 2) to the internal primed steel surface of the tank or tank (Fig. 2), the appearance of “cold bridges” is eliminated, as a result of which a continuous thermal barrier coating is formed, which allows stabilization of climatic parameters inside the tank or tank when changing external influences. When a layer of heat-insulating material 2 (Fig. 2) is applied to the external primed steel surface of the tank or tank (Fig. 2), the external surface of the tank or tank is heated by direct sunlight and solar radiation during the warm season.

The experiments and calculations showed that a thermal insulation coating with a thickness of 1 mm provides a temperature difference of 55 degrees Celsius in a stationary mode under normal conditions.

Thermal insulation material consists of the following components: acrylic binder; composition of catalysts and fixatives; ceramic ultrafine spheres with discharged air.

Table 1 shows the technical characteristics of a liquid heat-insulating coating [1].

Table 1 - Technical characteristics of a liquid thermal insulation coating:

The use of a material with a thickness of 1.5 to 3 mm as a heat-protective coating will allow:

- improve the insulating properties of the tank or tank;

- significantly reduce the forced loss of liquids inside the containers as a result of evaporation by lowering the temperature of the outer surface of the tank or tank;

- reduce the complexity of the work due to the high speed of the thermal insulation coating;

- provide 100% coverage of the design of the tank or tank of any geometric shape;

- provide anti-corrosion protection of the material of the structure;

- eliminate the formation of condensation;

- reduce heating of the outer surface of the tank or tank from direct sunlight and solar radiation in the warm season.
