Portable temperature difference electricity generation device based on catalytic combustion

Abstract

The invention provides a portable thermoelectric generating set based on catalytic combustion, which comprises one group of thermoelectric generating modules and a fuel storage tank; each group of the thermoelectric generating modules comprises two thermoelectric generating modules; a catalytic combustion heat source channel is arranged on adjacent side walls of the two thermoelectric generating modules; fuel preheating channels are respectively arranged on opposite sides of the two thermoelectric generating modules, that is, the catalytic combustion heat source channel is positioned at the hot ends of the thermoelectric generating modules, and the fuel preheating channels are positioned at the cool ends of the thermoelectric generating modules; the catalytic combustion heat source channel is a serpentiform channel, of which an admitting port is communicated with the fuel preheating channels, and an outlet thereof is a waste discharge outlet; and the fuel preheating channels are connected with the fuel storage tank. The portable thermoelectric generating set adopts catalytic combustion to provide heat to the thermoelectric generating modules, realizes smokeless combustion under a relatively low temperature, has high safety, has the characteristics of simple structure, light weight, convenient transportation, high specific energy, longer time service, etc., and is especially convenient to be used as a one-man power supply and as a power supply for field purposes.

Description

technical field [0001] The invention belongs to the technical field of micro power generation, and in particular relates to a portable thermoelectric power generation device based on catalytic combustion, which is suitable for military individual power supply, field and portable power supply. Background technique [0002] In the prior art, portable electrical devices include: power supplies for individual soldiers, notebook computers, etc., and these power supplies are mostly rechargeable batteries, such as lithium batteries; however, a shortcoming of rechargeable batteries is that the specific energy is not high, and they can be used continuously Time is limited, and generally can only be used continuously for several hours, so it brings inconvenience to people's production and life. In order to solve this problem, people began to develop new power sources, including micro-proton exchange membrane fuel cells, which can continuously convert the input hydrogen energy into ele...

Problems solved by technology

The usual practice is to use boiler and flue gas waste heat for heating, or use solar heat for heating, use fuel combustion for heating, and use garbage incineration for heating. However, the disadvantages of using the above types of heat sources are that they are not conducive to portability and the specific energy is not high. , especially not conducive to single source and field electricity, in addition, the high temperature higher than 1000 ℃ generated by the combustion of combustibles such as fuel and garbage is not conducive to carrying and safe use
