Waste heat utilization thermoelectric power generation pipeline device

Abstract

The invention discloses a novel pipeline device aiming at transforming low-grate heat energy of living industry into electric energy. The pipeline device is mainly composed of five parts such as a heat flow pipeline, a heat transfer device, a thermoelectric power generation module, a cooling system and an electric power storage control module. Waste heat in the heat flow pipeline is transmitted to a hot end of the thermoelectric power generation module through working medium phase change in the heat pipe heat transfer device, and a cool end of the thermoelectric power generation module is continuously cooled by the cooling system, so that the two end of the power generation module is enabled to form temperature difference to generate power. The electric power storage control module is used for ensuring the continuity of energy transformation and stability of power output. For an existing pipeline, a pipeline clamping thermoelectric power generation device is designed additionally. Theories are basically the same, but a heat conduction glue layer is added between the existing pipeline and the heat pipe heat transfer device to reduce thermal resistance. The clamping device can be designed according to the existing pipeline size in a matching mode. The waste heat utilization thermoelectric power generation pipeline device aims at solving the problems that the thermoelectric power generation module is not influenced by limiting of the pipeline outside in an existing industrial waste heat recovery thermoelectric power generation technology and heat conduction efficiency is not high.

Description

Technical field [0001] The invention relates to a semiconductor thermoelectric power generation technology, in particular to a thermoelectric power generation technology based on the principle of heat pipes for the utilization of waste heat from pipes of any shape in matching horizontal and belongs to the field of industrial waste heat power generation. Background technique [0002] As the contradiction between energy supply and demand continues to deepen, the energy problem has become an urgent problem in the development of human society. While vigorously developing new energy, it is also a feasible way to improve the utilization efficiency of primary energy in the industrial sector. my country's energy utilization rate is only about 30%, which is about 10% lower than that of developed countries. At least 50% of industrial energy consumption is directly discarded as waste heat in various forms. If this part of the waste heat can be used, it can not only effectively improve the ...

Problems solved by technology

However, the promotion and application of domestic medium and high temperature waste heat recovery technology is insufficient, and the level of low temperature waste heat recovery technology is low, resulting in a very low overall efficiency of industrial waste heat recovery in my country.

[0005] In the existing heat pipe thermoelectric power generation technology, most of the research focuses on the improvement of the power generation efficiency of the thermoelectric power generation module, and the research investment is large and the progress is slow

However, little attention has been paid to the heat transfer process from the pipe to the hot end of the thermoelectric power generation module. The heat pipe or the thermoelectric power generation module is simply attached to the pipe surface or inserted into the pipe, which inevitably makes the layout of the components affected by the shape of the pipe or even increased. The fluid flow resistance in the pipeline increases the operating burden of the system, and makes the heat pipe and thermoelectric power generation module in a relatively harsh working environment, which cannot be in the best working condition, and the damage rate increases, which virtually increases the cost of funds
