Description
Technical Field
The invention relates to a double-acting Stirling engine adopting a composite heat source, and belongs to the technical field of utilization of a thermomechanical engine.
Background
A Stirling Engine (Stirling Engine) is an externally heated closed cycle piston Engine. In such machines, the working medium (typically hydrogen, helium or air) is enclosed in a circulation circuit, and is heated externally, expanded at a higher temperature and pressure, and the piston is pushed to move; the working medium is cooled by a cooler, so that the working medium is compressed at lower temperature and pressure, and positive circulating work is obtained. The thermodynamic process is carried out according to the Stirling cycle, namely, the thermodynamic process consists of four reversible processes of isothermal heat absorption, isothermal heat release and isothermal heat absorption.
The double-acting Stirling engine commonly used at present is formed by combining a heater, a cylinder, a cooler and a heat regenerator according to a certain sequence of hot and cold structures, and the number of the cylinders is four. The high-pressure gas working medium is heated and expanded at the upper part of the cylinder to drive the piston to move downwards; the gas at the lower part of the piston enters a cooler and a heat regenerator and enters a heater again to be heated; after the piston moves downwards to the bottom, the crankshaft (or the sloping cam plate) drives the piston to move upwards, gas in the cylinder enters the heater to heat, then enters the regenerator to regenerate heat, and then enters the cooler to cool, thus completing a circulation action. The pistons and the gas in the four cylinders alternately circulate, the four pistons alternately move up and down to generate up and down reciprocating linear motion, and the piston rod drives the crankshaft (or the swash plate) to rotate to output work, so that the work is smoother.
However, the conventional stirling engine generally can only use one heat source for heating, for example, when solar heating is used, the heat absorber needs to be designed into a heat absorbing cavity type with high efficiency for solar heating, and other heating modes cannot be utilized, otherwise, when heating modes are used, solar heating cannot be utilized again.
Disclosure of Invention
The invention aims to solve the technical problems that: the double-acting Stirling engine capable of being heated by various heat sources is provided, and all-weather operation can be realized on the premise of fully utilizing solar energy.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: a double-acting Stirling engine adopting a composite heat source comprises a heater, a cylinder, a cooler and a heat regenerator, wherein the number of the cylinder and the heat regenerator is four; the cylinders are uniformly distributed circumferentially and are arranged on the engine body, the heat regenerators are uniformly distributed circumferentially and are arranged on the engine body, and the heat regenerators and the cylinders are staggered; the top of any heat regenerator is connected with a heat regenerator header, and four heat regenerator headers are enclosed into a circular ring; the top of any cylinder is connected with a cylinder header, the four cylinder headers are in one-to-one correspondence with the four heat regenerator headers and also enclose a circular ring shape, and the circular ring shape enclosed by the four heat regenerator headers and the circular ring shape enclosed by the four cylinder headers are concentrically arranged; the heater comprises a transparent glass barrel, a heat absorption pipe cavity and a plurality of heat absorption pipes, wherein the bottom of the transparent glass barrel is provided with a light reflection cone, the heat absorption pipe cavity is arranged outside the transparent glass barrel and surrounds the transparent glass barrel, the heat absorption pipes are positioned in the heat absorption pipe cavity, the top of the transparent glass barrel is provided with a lighting opening, the lighting opening is covered with a transparent glass cover plate, the heat absorption pipe cavity is provided with an inlet and an outlet, and the heat insulation body is arranged outside the heat absorption pipe cavity and at the bottom of the transparent glass barrel; the cylinder header and the heat regenerator header are communicated through heat absorption pipes, and the heat absorption pipes are integrally in an inverted U shape and are vertically arranged.
Preferably, the heat regenerator, the air cylinder, the heat regenerator header, the air cylinder header and the heat absorption pipe are all made of high-temperature alloy or heat-resistant steel materials.
When the invention is used, when gas is heated in the heat absorption pipe, the heated gas expands in the cylinder to drive the piston in the cylinder to move downwards, and when the piston rod moves downwards along with the piston, the crankshaft or the sloping cam plate transmission mechanism connected with the piston is driven to rotate to output work; when the piston moves to the bottom of the cylinder, the piston starts to move upwards due to the rotation of the crankshaft or the sloping cam plate transmission mechanism, high-pressure gas flows back, absorbs heat in the heat absorption pipe, and part of heat of the gas is stored in the heat regenerator through the heat regenerator and then enters the cooler for cooling. When the piston moves to the top, gas flows from the cooler to the heat regenerator, absorbs part of heat energy in the heat regenerator to heat, and enters the heat absorption tube again to heat, and the heated heat expands in the cylinder to complete a Stirling cycle.
The invention improves the traditional plane heat absorption tube into a circle of heat absorption tube which is vertically arranged, and vertically installs the heat absorption tube in the heat absorption tube cavity surrounded by the heat insulator and the transparent glass barrel, so that the heat absorption tube cavity is manufactured into an annular cavity, when in use, the transparent glass barrel can not only introduce sunlight to heat the heat absorption tube, reduce the absorption loss of the collected sunlight, but also can play a role in heat preservation of the heat absorption tube cavity, and any heat source such as high-temperature fused salt or high-temperature flue gas is directly introduced into the heat absorption tube cavity to heat the heat absorption tube, thereby realizing the heating of gas by utilizing a composite heat source, enabling the Stirling engine to utilize solar energy, but also utilize the fused salt or the high-temperature flue gas introduced into the heat absorption tube cavity to heat with heat absorption tube in a heat exchange mode, and enabling the Stirling engine to work around the clock. In addition, the bottom of the transparent glass barrel is additionally provided with the reflecting cone, so that all incoming sunlight can be reflected into the heat absorption tube cavity as much as possible.
According to the solar heat exchange tube, when the solar energy is insufficient, the heat absorption tube cavity can be connected with any heat source such as high-temperature flue gas and the like to exchange heat with the heat absorption tube, preferably, molten salt is connected into the heat absorption tube cavity, namely, an inlet and an outlet on the heat absorption tube cavity are respectively a molten salt inlet and a molten salt outlet, and the height of the molten salt inlet is smaller than that of the molten salt outlet. At the moment, the heat absorption tube cavity is subjected to heat exchange by introducing molten salt, and when the solar energy is sufficient, the molten salt stops being injected into the heat absorption tube cavity, and the height of the molten salt inlet is smaller than that of the molten salt outlet, so that the molten salt can flow back, and the molten salt is prevented from solidifying in the heat absorption tube cavity. In addition, a small amount of molten salt remained in the heat absorption tube cavity in the use process can play a role in heat storage and heat preservation of the heat absorption tube, so that the Stirling engine can run more stably.

Preferably, the two ends of the heat absorption pipe are respectively brazed on the heat regenerator header and the cylinder header, the circle center of a circular ring shape surrounded by four heat regenerator headers is used as a reference point, and the included angle of a connecting line between the two ends of the heat absorption pipe and the reference point is 3-8 degrees. The heat absorption pipes are arranged in a staggered manner, so that incident solar energy which does not irradiate the inner ring heat absorption pipes and penetrates through the gaps of the inner ring heat absorption pipes can be absorbed by the outer ring heat absorption pipes, and the efficiency of the heat absorption pipes for absorbing sunlight and exchanging heat with other heat sources is improved.
