Closed-type fuel gas spiral pipe rotor engine device

Abstract

The invention discloses a closed-type fuel gas spiral pipe rotor engine device. On the basis of a closed-type gas turbine device, a spiral pipe rotor engine is used to replace a gas turbine to transform thermal energy into mechanical power. Due to the fact that the thermal energy transforming efficiency of the spiral pipe rotor engine is higher than the thermal energy transforming efficiency of the blade-type gas turbine, the cycle thermal efficiency of a closed-type fuel gas engine is improved correspondingly, the temperature of exhaust gas is relatively low, and the exhaust gas can be cooled through cool water and can also be cooled through air. A generator is electrically connected with a controller battery in a speed regulation motor device; the speed regulation motor device is connected with a volume changing type gas compressor in a powered mode and can regulate the speed and output power to drive the volume changing type gas compressor; and the spiral pipe rotor engine is connected with loads including the generator in a powered mode and outputs power to drive the loads including the generator, so that the movable closed-type gas turbine device can be used not only for commercial power generating but also as engines used in automobiles, ships and the like.

Description

technical field [0001] The invention relates to a thermal power device, specifically a closed gas helical tube rotor engine device. Background technique [0002] Existing thermal power devices are divided into internal combustion and external combustion. For example, piston internal combustion engines and open-loop gas turbine devices use internal combustion heating, and Stirling engines and closed-loop gas turbine devices use external combustion heating. It is reported that the gas turbine of the closed gas turbine device is used for commercial power generation, and the Stirling engine has many technical problems that have not been solved so far, and it has no practical commercial value. The external heating method can be applied to a variety of fuels, especially low-quality fuels, and nuclear energy can also be used, so its biggest advantage is that it can convert any external heat energy into mechanical work. [0003] The gas turbine of the closed gas turbine device is c...

Problems solved by technology

[0004] However, due to the use of bladed turbines, the temperature of the exhausted air is relatively high, and a large amount of cooling water is required to cool it, so its biggest disadvantage is that the thermal efficiency of the cycle is relatively low

The compressor adopts axial flow or centrifugal compressor, which is relatively large in size, and cannot be moved or rotated with speed regulation. Currently, it is only used as a fixed commercial power generation device.

The above shortcomings limit the use of the gas turbine in the closed gas turbine device to play its technical advantages in other aspects

[0005] In related patent applications such as Patent Application No. 201410415779.3, a method and device for improving the efficiency of a turbine engine, and Patent Application No. 201610813636.7, a spiral tube rotor and its engine, the spiral tube rotor is used to replace the blades of the prior art gas turbine engine. type turbine rotor to improve cycle heat efficiency and convert heat energy into mechanical work, which constitutes a gas-fired helical tube rotor engine that uses air as the working medium and works in an open-loop thermodynamic cycle. They must heat the working medium from the internal combustion method and heat Source fuel options are somewhat limited
