Abstract

The invention relates to a thermohydraulic pressure increase method and to the application thereof. Such a technical solution is required primarily in the field of energy management, in mechanical engineering, and in chemical plant engineering. In a hydraulic system, according to the prior art a hydraulic pump, which is driven by a motor disadvantageously requiring premiums forms of energy, such as electricity, diesel, or gasoline, is used to achieve the pressure increase. Some working fluids very drastically change the density thereof close to and above the critical point as the temperature rises, and transition into the gaseous state and under high pressure multiply the volume thereof if additional energy is supplied without density leaps at temperatures far below 100ºC. If the substance-specific system pressure and the system temperature can be adjusted to a hydraulic process, the waste heat can be used for volume change work. The aim is to achieve volume change work by way of waste heat in a thermal process and apply said work to a hydraulic process, for example, in order to then drive presses or generators in stationary industrial systems.

Description

Thermo-hydraulic method for increasing the pressure of various working fluid and its application

description

1. The invention relates to a thermo-hydraulic pressurization process and its application. Such a technical solution is required primarily in the energy in mechanical engineering and in chemical plant. In a hydraulic system, the pressure increase takes over the prior art, a hydraulic pump which is driven by a motor.

2 For this purpose, high-quality energy such as electricity, diesel or gasoline needed. Hydraulic system components are marketable, found everywhere in the art application and are at a high level of development. A disadvantage is the high quality drive energy could be mentioned. Some working fluid change near and above the critical point the temperature rises strongly

3 their density and go on further supply of energy density without cracks at temperatures well below 100 0 C in the gaseous state at high pressure and increase its volume several-fold. the substance-specific system pressure and temperature system can be adapted to a hydraulic process, the option to use waste heat to volume change work is created

4 It is therefore an object of the invention to achieve volume change work by means of waste heat in a thermal process to transfer it to a hydraulic processes, and then to drive, for example, pressing or generators in stationary industrial plants.

The object is essentially characterizing by

dissolved 5 Characteristics of claims 1 to. 4 Thereafter, in a pressure vessel (2), the liquid working fluid (1) is initially heated isochorically by means of heat exchanger (3) so that pressure and temperature rise. The pressure vessel (2) is in direct communication with a double cylinder (5), wherein the second side is filled with hydraulic oil (9). At the start of the piston (10) is at the top (high density). The pressure valve

6 (8) opens only when the internal pressure rises above the hydraulic pressure. Then, hydraulic oil flows into the high-pressure vessel (11) and can be used to work (12) are used. has After the pressure valve (8) opened, the further heating of the working fluid is isobaric (upper hydraulic pressure), until the lower reversal point in a double cylinder (5) is reached (small density). With cooling, the volume is reduced again, the pressure drops and the low pressure of the hydraulic system (13) pushes the piston back to the upper starting position. Since the heating and cooling of the working fluid is steadily rising or falling, can be regenerated much of the heat. Figures 2 and 3 show an application such as thermal hydraulic cylinder 12 are connected together. In this case, in a cycle of 5 thermal hydraulic cylinders are connected to the regeneration, a heated and cooled. can be sucked and pressed with the next cycle changes by regulating the terminal assignment, so that per cycle an entire stroke.
