Slight temperature difference heat energy generating set

Abstract

The invention relates to a slight temperature difference heat energy generating set, which is composed of a heat energy converter, a ratchet drive mechanism and a power generation input device, wherein the converter is formed by sleeving two long tube neck containers and sealing the sleeve joint, each long tube neck container has an open big end, an isolator is arranged in the tube, thereby forming two isolated spaces containing liquid and gas, and the isolator is breathable but not liquid-permeable; the support axis of the tube neck enables the center of gravity of the whole body deviates to one end, and the liquid level on the upper end is higher than the isolator; when the temperature is high at the lower part and low at the upper part, gas at the lower end of the tube is under positive differential pressure, so that the center of gravity moves towards the upper end part along with the liquid at the upper end; when the lower end swings upwards to the horizontal position, the internal gas differential pressure is zero, so that the two ends swing in reverse directions, and the circulation goes in the same mode; and the drive mechanism is driven by a plurality of ratchet wheels and sprocket wheels in parallel, so that reciprocating swing is converted into intermittent rotation of the large sprocket wheel, converted into continuous rotation of the small sprocket wheel shaft and input to the generator after two-stage acceleration. The generating set can generate power by using heat of earth surface, industrial waste heat, solar heat and heat in air.

Description

technical field [0001] 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 small temperature difference between two ends of a thermal energy converter. Background technique [0002] At present, there are two types of thermal power generation devices used in industrial production: geothermal power generation and solar thermal power generation devices. Geothermal power generation devices generally use high-temperature geothermal steam to generate electricity. First, the steam from the geothermal well is input into the wellhead separation device to separate the solid impurities carried in it, and then passed into the steam turbine for power generation. The exhaust steam is condensed and then discharged. To achieve economical efficiency, geothermal resources above 150 degrees Celsius are required. If the required temperature cannot be reached...
