A thermoelectric conversion device based on liquid fuel combustion

Abstract

A thermoelectric conversion device based on the combustion of liquid fuel, comprising a combustion cylinder, a burner is arranged inside the combustion cylinder, an ignition mechanism is arranged on the top of the burner, a fuel evaporation tube is arranged inside the burner, and the lower part of the fuel evaporation tube is filled with an oil-absorbing porous medium, There is a fuel steam hole in the upper part; an oil pump is installed at the lower end of the fuel evaporation tube, and the oil pump is connected to the lower end of the fuel evaporation tube; a mixing chamber is formed between the upper part of the fuel evaporation tube and the inner wall of the burner, and an air is formed between the lower part of the fuel evaporation tube and the inner wall of the burner. The conveying channel and the air conveying channel communicate with the mixing chamber; the flue gas channel is formed between the outer wall of the burner and the inner wall of the combustion tube; the outer wall of the combustion tube is provided with a thermoelectric power generation module. The invention fully burns the liquid fuel, converts heat energy into electric energy, reduces environmental pollution caused by using batteries, reduces the burden of outdoor movement, and does not need to interrupt the power supply for a long time when using electric equipment.

Description

technical field [0001] The present invention relates to the technical field of thermoelectric power generation, power supply technology, and burner technology, and in particular to a thermoelectric conversion device based on liquid fuel combustion. Background technique [0002] For military personnel, geological prospecting personnel and other workers who are often in the field, they need to use many electronic equipment, such as navigation equipment, communication equipment, camera equipment, etc. For these mobile equipment, the power supply is mainly provided by batteries. However, rechargeable batteries and disposable batteries contain many hazardous substances that cause serious pollution to the environment. These hazardous substances pose potential dangers to human and animal health. Therefore, these batteries are mostly collected and processed separately, which requires Expensive price; the battery has a low energy density, and the quality of the battery is relatively ...

Problems solved by technology

However, rechargeable batteries and disposable batteries contain many hazardous substances that cause serious pollution to the environment. These hazardous substances pose potential dangers to human and animal health. Therefore, these batteries are mostly collected and processed separately, which requires Expensive price; the battery has a low energy density, and the quality of the battery is relatively large in practical applications, which is not conducive to the outdoor movement of field workers; in addition, the charging time for rechargeable batteries is relatively long
