Problems solved by technology

Practice has proved that the effect of using water or air to heat the expansion gas outside the cylinder wall is not obvious, which leads to the actual expansion process close to adiabatic expansion, which not only reduces the system efficiency of the expander, but also easily causes fros

Example Embodiment

[0035] Example 1

[0036] figure 1 It is a structural schematic diagram of Embodiment 1 of the hydraulic isothermal expansion power system of the present invention. The system includes a piston 5, a cylinder 3, a crank connecting rod mechanism, a high-pressure gas working medium storage tank 22, a heating medium storage tank 21 and a heat exchanger 24. The piston 5 is slidably installed in the cylinder 3, and the crank connecting rod mechanism includes a connecting rod 12 And crank 13, one end of connecting rod 12 is connected with piston 5, and the other end is connected with crank 13, and the top of cylinder 3 is equipped with intake valve 2 and annular injector 4, and the intake port 1 of intake valve 2 is connected with high-pressure gas working fluid storage The tank 22 is in communication, and the annular injector 4 is in communication with the heating medium storage tank 21, so as to atomize the heated heating medium or form foam and inject it into the cylinder 3 at a ...

Example Embodiment

[0038] Example 2

[0039] figure 2 It is a schematic structural diagram of Embodiment 2 of the present invention, and its main structure is the same as that of Embodiment 1. Compared with Embodiment 1, the difference between the heating medium and the gas is that after the heat exchange between the heating medium and the gas through the heat exchanger 24 and before entering the cylinder 3, The two enter a mixer 25, and then the fully mixed gas-liquid two-phase flow is sprayed into the cylinder 3. It is no longer necessary to install an annular injector on the top of cylinder 3.

Abstract

The invention relates to an isothermal expansion power system by hydraulic pressure. The isothermal expansion power system comprises a piston, an air cylinder, a crank connecting rod mechanism, a high-pressure gas working medium storage tank, a heating medium storage tank and a heat exchanger. Liquid in the heating medium storage tank is heated by an outside heat source. The high-pressure gas working medium storage tank stores high-pressure gas and liquid. When the system works and high-pressure air enters the air cylinder from the high-pressure storage tank, a liquid pump works, the liquid in a liquid tank is absorbed to enter the high-pressure gas working medium storage tank, and the high-pressure gas working medium storage tank is made to maintain constant pressure. High-pressure gas enters the air cylinder to drive the piston to do work, meanwhile, high-temperature heating media from the heating medium storage tank enter the air cylinder in a mist or foam shape, the quasi isothermal expansion process is achieved, and therefore the output work quantity of unit working media is improved.

Description

technical field [0001] The invention relates to a hydraulic isothermal expansion power system, specifically, the system includes an isothermal expansion machine, a liquid tank, a high-pressure storage tank and a water pump; the liquid in the liquid tank is heated by an external heat source; the high-pressure storage tank stores high pressure Air and liquid, when the system is working and the high-pressure air enters the isothermal expander from the high-pressure storage tank, the liquid pump works by absorbing the liquid in the liquid tank and entering the high-pressure storage tank, so that the high-pressure storage tank maintains a constant pressure; the high-pressure air enters the expander to drive The expander works, and at the same time, the high-temperature liquid from the liquid tank enters the expander cylinder in the form of mist or foam to realize the quasi-isothermal expansion process, thereby increasing the output power per unit of working fluid.
