Hot-air balloon based on methanol fuel battery

Abstract

The invention discloses a hot-air balloon based on a methanol fuel battery. According to the technical scheme provided by the invention, the hot-air balloon based on the methanol fuel battery comprises an airbag and a hoisting basket, wherein the hoisting basket is connected to the lower part of the airbag; a methanol fuel battery pack is arranged in the hoisting basket; the methanol fuel battery pack comprises a high-temperature exhaust tube; the high-temperature exhaust tube is used for exhausting a high-temperature waste gas into the airbag; the methanol fuel battery pack further comprises a methanol tank and a power access; a fan is arranged at the high-temperature exhaust tube; the fan is connected with the methanol fuel battery pack; an electric heating device is arranged in the high-temperature exhaust tube; the electric heating device is supplied with power from a methanol fuel battery; the electric heating device adopts a silicon nitride electric heating sheet; the silicon nitride electric heating sheet is connected with the methanol fuel battery pack; the fan comprises blades; the blades are coated by high-temperature resistant coatings. By adopting the scheme disclosed by the invention, the power access is available, so that the hot-air balloon is applicable to long-distance travelling.

Description

technical field [0001] The invention relates to the technical field of methanol fuel cells, in particular to a hot air balloon based on methanol fuel cells. Background technique [0002] A hot air balloon is a balloon that uses hot air as the buoyant gas. Hot air balloons are the earliest flying tools, and now flying in hot air balloons has become a favorite aviation sport. In addition, hot air balloons are also commonly used in aerial photography and aviation tourism. The structure of the existing hot-air balloon is that there are large openings and hanging baskets for cold air heating at the bottom of the air bag. The density decreases after the air is heated, and the density is about 0.95kg / m when the temperature reaches 100°C 3 , is 1 / 1.3 of the air, so the lift-off is not high. Modern hot air balloons are equipped with simple flight instruments, fuel tanks and blowtorches in the basket. When launching from the ground, ignite the blowtorch, heat the air and fill the a...
