Swing cylinder suspension heating direct-line generator

Abstract

The invention relates to a swing cylinder suspension heating direct-line generator. A swing cylinder heat energy converter is a novel heat engine. A hot end liquid level suspension plate heating structure without a partition in a pipe is adopted, a working medium is low boiling point liquid, and the heat energy conversion rate is higher than other heat engines. Natural gas, shale gas, mine gas andgarbage biogas can be used for generating electricity, and solar thermal power and geothermal energy and industrial waste heat can be used for generating the electricity. A suspension heat conductionplate with a guide mechanism in the converter floats on the hot end liquid level, moves up and down with the liquid level and heats the liquid level, the small temperature difference between two endscan generate a large saturation vapor pressure difference, liquid is pressed to the cold end, the hot end liquid level drops, the cold end liquid level rises, the center of gravity moves to the coldend and over a supporting axis, the heat energy converter swings, and a cold end connecting rod transmission mechanism drives a promoter up and down in a linear power generation device to generate theelectricity.

Description

[0001] Technical field [0002] The invention belongs to the technical field of thermal power generation, and in particular relates to a thermal power generation device capable of generating electricity by swinging with a slight temperature difference between two ends of a thermal energy converter. Background technique [0003] At present, the relevant technology is an invention patent - micro-temperature difference thermal power generation device. After research, it is found that there are two problems. First, the pendulum energy converter adopts an integral heating structure with a spacer in the tube and a heating end. The spacer can pass through gas but not liquid. When the liquid level at the cold end rises, the gas space at the cold end is compressed, resulting in an increase in the vapor pressure of the working medium. At this time, the equilibrium temperature of the liquid-gas two-phase is higher than the external ambient temperature, and the vapor condenses into a liq...

AI Technical Summary

Problems solved by technology

When the pendulum swings to the horizontal position, the medium steam at the hot and cold ends penetrates through, and the steam at the hot end enters the cold end, while the liquid medium produced by condensation at the cold end cannot return to the hot end. After several swings, the liquid at the cold end increases, and the conversion The initial center of gravity of the device drifts to the cold end, and the swing cylinder gradually fails to work

If the spacer is removed, the hot end cannot adopt the overall heating structure, because the hot end is heated as a whole, and the temperature of the medium at the cold end will gradually increase, resulting in a gradual increase in the temperature of the working medium of the entire converter, and finally it will not work

[0004] Second, there is a problem with the form of its rotary power generation

Because the converter support shaft is used to drive the ratchet to swing, and then to rotate the sprocket, gear, and gearbox to rotate, and finally to rotate the generator, the friction chain is too long and the friction coefficient is too large to meet the requirements of industrial use.

In addition, this form of rotary power generation cannot realize single-machine power generation. Several converters must drive a long shaft to work in a high degree of coordination. However, the actual situation is that the swing of the pendulum is affected by too many random factors and cannot be highly coordinated.

[0005] The above problems indicate that the existing micro temperature difference thermal power generation device cannot meet the requirements of micro temperature difference thermal power generation
