Stirling heat engine based on liquid radioactive waste concentrates

Abstract

The invention discloses a Stirling heat engine based on liquid radioactive waste concentrates. The Stirling heat engine based on liquid radioactive waste concentrates comprises a Stirling heat engine base. Multiple sealed air cylinders are arranged in the Stirling heat engine base. The outer ends of piston rods in the air cylinders are connected with a crank-link mechanism. U-shaped air pipes are connected to the air cylinders and heat exchangers are arranged on the U-shaped air pipes. One ends of the U-shaped air pipes are communicated with the hot ends of the upper ends of the air cylinders. The other ends of the U-shaped air pipes are communicated with the cold ends of the lower ends of the air cylinders. A sealed box body is arranged at the upper end of the Stirling heat engine base. A material storage tank is arranged in the middle of the box body and liquid radioactive waste concentrates are contained in the material storage tank. The material storage tank and the inner wall of the box body form an annular cavity. The bottoms of the U-shaped air pipes penetrate into the annular cavity and a pair of electronic poles is arranged on the two sides of the material storage tank. A controller is arranged outside the box body and the electronic poles are connected with the controller through guide wires. Thus, the Stirling heat engine based on liquid radioactive waste concentrates has the advantages of being stable in heat source, stable in working performance and high in working efficiency.

Description

technical field [0001] The invention relates to the technical field of Stirling heat engines, in particular to a Stirling heat engine based on liquid radioactive waste concentrate. Background technique [0002] The Stirling engine is a unique heat engine, because the theoretical efficiency is almost equal to the theoretical maximum efficiency, called the Carnot cycle efficiency, so the Stirling engine has a wide range of applications in new energy power generation and military industry. The Stirling engine generates power by expanding the gas when it is heated and compressing it when it is cold. The air-conditioning chamber is cooled, and this cycle process is repeated repeatedly. The outer end of the piston handle is connected to the crank linkage mechanism, thereby driving the three-phase generator to rotate, and converting mechanical energy into electrical energy. The external heat source of the common Stirling heat engine is usually heated by fuel combustion or solar he...
