Negative-pressure engine

Abstract

The invention provides a negative-pressure engine which takes hot gas as power and converts heat into mechanical force in a negative pressure form to drive a bent axle to rotate. In a working process, a piston in a hot gas cylinder moves to suck outer hot gas into the hot gas cylinder; then the sucked hot gas is pushed into a cold gas cylinder immersed into cold water; an air valve is closed and the hot gas is cooled in the cold gas cylinder to generate negative pressure; the piston is pulled to move to drive the bent axle to rotate. The engine does not have ignition and combustion and does not consume heat energy. When the engine work, the needed hot gas can be water steam, smoke, combusted gas, underground hot gas and waste gas discharged by other engines. Only continuous hot gas supply and a lot of cooling water are needed. The engine can be used for environments including thermal power plants, nuclear power stations, large-shaped ships, heating boilers and the like. The engine is used for changing heat of the hot gas into effective mechanical force; meanwhile, the waste gas can be cooled and purified and the pollution to the atmosphere is reduced.

Description

technical field [0001] Negative pressure engine belongs to the field of heat engine. A heat engine is a device that converts heat energy generated by fuel into mechanical force to rotate a crankshaft or wheel shaft and output power. The types of heat engines that have been invented now include steam engines, steam turbines, internal combustion engines, turbines, etc. Background technique [0002] The common point of the above several engines is that they are all powered by the way heat is converted into positive pressure. After the mechanical force is generated when the gas is heated and expanded, the remaining hot gas is discharged into the atmosphere. Due to the low thermal efficiency, it played a role in the past when energy was abundant, but now it seems a little backward in energy shortage and serious air pollution. Some have been eliminated, and some are still being used. Because it is difficult to achieve low temperature When there is no better invention for the util...

AI Technical Summary

Problems solved by technology

People only know to use the positive pressure generated by the thermal expansion of the gas, but they have not noticed that when the hot gas is discharged into the atmosphere and cools down, the volume will shrink to its original size, and negative pressure will be formed at the same time. People cannot directly see the existence of this negative pressure. Not to mention turning this negative pressure into an effective mechanical force
