Abstract

The invention relates to the field of heat and electricity, and in particular to methods for manufacturing pipeline transport of the above purpose. The technical result is the expansion of technological capabilities and increased efficiency through the use of pipeline transport simultaneously for heat and electricity. The specified technical result is achieved in that the pipeline transport for moving the coolant in the form of a certain working medium in a liquid, gaseous or vapor state is made of pipelines, inside one of which there are two internal thin-walled pipelines with a gap relative to the external thick-walled rigid pipeline. Moreover, this gap is filled with a gaseous medium, for example an inert gas (nitrogen), under a pressure of at least 1.01 relative to the pressure under which the working medium is supplied through internal pipelines. Inside the external thick-walled pipeline, for example steel, two internal thin-walled tubing-sleeves of copper, aluminum or other metals, usually used for wires of power lines, are laid. One of the thin-walled internal pipelines-hoses delivers coolant, for example, hot water for heating or sanitary purposes, to the consumer from the boiler room or CHPP, and the already used coolant having a lower temperature is returned in the opposite direction through the other internal piping-hoses. New in the invention is that the same internal pipelines, when using external electrical insulation, as well as external thermal insulation of the entire pipeline transport, are used simultaneously instead of wires for transmission from an electric power station or thermal power plant to a consumer of electric current, which also contributes to an increase in the temperature of the working medium supplied relative to the consumer in both forward and reverse directions.

Description

The invention relates to the field of heat and electricity, for example residential buildings, and in particular to methods for manufacturing pipeline transport of the above purpose.

A known method of manufacturing a pipeline transport, which consists in the fact that the pipeline transport for moving a certain working medium is made of pipelines, inside one of which at least one internal thin-walled, easily elastic deformable pipeline with a gap relative to an external thick-walled rigid pipeline is located, this gap is filled with a gaseous medium, for example an inert gas, at a pressure of at least 1.01 relative to the pressure under which t through the internal pipeline working medium, / cm. RF patent No. 2097647, cl. F 17 D 1/00, publ. 11/27/99, bull. No. 33 /, adopted as a prototype.

The disadvantage of this method is the narrow technological capabilities due to the use of pipeline transport only for moving working media in a liquid, gaseous or vapor state.

The technical result of the invention is the expansion of technological capabilities and increased efficiency through the use of pipeline transport simultaneously for heat and electricity.

The specified technical result is achieved by the fact that inside the external thick-walled pipeline, for example steel, two internal thin-walled, easily elastic deformable pipe-sleeves are laid, made for example of copper, aluminum or other metals, usually used for wires of power lines. One of the thin-walled internal pipelines-hoses delivers a heat carrier, for example, hot water for heating or sanitary purposes, to the consumer from a boiler room or CHP. In another internal thin-walled sleeve pipe, the already used coolant having a lower temperature is returned in the opposite direction. The same internal pipelines-sleeves, when applying their external electrical insulation, as well as the external thermal insulation of the entire pipeline transport, are used simultaneously instead of wires for transmission of electric current from the power plant or thermal power plant to the consumer, which also contributes to an increase in the operating temperature through the arising electromagnetic field and eddy currents

environment transported relative to the consumer in both forward and reverse directions.

The method is as follows. Standard thick-walled rigid pipes, for example, steel, and thin-walled tubing-sleeves made of metals that conduct electricity well, with external electrical insulation, tapered and rolled up in riots are delivered to the installation site of pipeline transport (underground, above-ground, above-ground). Two thin-walled pliable hose lines are placed inside thick-walled rigid pipes. The latter, before or after laying in them internal thin-walled piping-sleeves, are connected into a single external thick-walled rigid pipe using blind or elastic couplings by means of one-piece or detachable connection of external pipes butt. For continuous installation, thin-walled internal pipelines-sleeves from separate riots are interconnected, and after laying them inside the external pipeline they are squeezed with water, giving the desired shape. The gap between the external pipe and the two internal pipe-hoses is filled with a gaseous medium, for example inert gas (nitrogen), under a pressure of at least 1.01 relative to the pressure under which, after commissioning, a working medium, for example, a coolant, is supplied through the internal pipe-lines in the form of water for heating or sanitary purposes. Moreover, hot water is supplied to the consumer through one of the internal pipelines-hoses, and chilled water in the opposite direction is supplied to the consumer. Outside, all pipeline transport is thermally insulated from the external environment. At the same time, the internal piping-hoses are used to transmit electric current over a distance, for example, to residential buildings, which also contributes to an increase in the temperature of the transported working medium.

The use of the invention extends the technological capabilities of pipeline transport by using it simultaneously for heat and electricity. Thanks to the manufacture of thin-walled internal piping, sleeves will save costly non-ferrous metal, commonly used in the manufacture of power lines. Due to the use of the described construction of pipeline transport, an external rigid pipeline can also be made thinner than with a conventional single-layer pipeline construction, which will also help reduce material consumption. Due to the elastic deformation of the internal thin-walled pipelines-hoses and shock absorption using a gaseous medium under pressure in the gap between the external and internal pipelines-hoses, the reliability of pipeline transport will increase, since it will dampen possible hydro- or pneumatic impacts that occur during transportation of the working medium, for example, a coolant in the form of hot water, steam, hot gas, and others. Such pipeline transport makes unauthorized access difficult.

to internal pipelines-sleeves. It can be used for laying in places subject to various undesirable effects of an objective (for example, earthquake) or subjective nature (for example, military operations or terrorist acts). In addition, due to the constant shaking and pulsation of the internal piping-hoses, unwanted solid deposits will not be deposited on their walls, which usually narrow the internal section of the pipelines, making it difficult to transport the working medium through them. A very important point is that with the passage of an alternating electric current through the pipe arms around them, an alternating magnetic field will be created, causing the appearance of a thermal effect. The heat generated in this case will heat the transported, for example, liquid, working medium, increasing the temperature of the latter, and, therefore, reducing its kinetic viscosity, which, in turn, will facilitate the process of moving the working medium through pipeline transport, reducing the energy costs of pumping it. In addition, the working medium in the form of a coolant, for example hot water used for heating or sanitary purposes, will have a higher temperature both in the direct and in the opposite direction to the consumer, which will increase the efficiency of use of the coolant.
