Method for generating electricity by means of low temperature exhaust heat of power plant

Abstract

The invention discloses a method for generating electricity by means of low temperature exhaust heat of a power plant and relates to an unconventional electricity generating method. The problems of excessively large exhaust heat discharge and environment pollution caused by heat of a thermal power plant or a nuclear power plant are mainly solved, and the waste heat is converted to electric energy is achieved through exhaust heat electricity generation. Theoretically, the situation of nonreversible entropy production during energy cycle is solved, that is, the entropy production direction is changed, and negentropy is achieved. Water potential energy is increased through equipment with the upward flowing function; the potential energy is converted to kinetic energy through water fall, and a water turbine is driven to generate electricity; meanwhile, the upward-flowing equipment absorbs a large amount of heat, including low temperature heat, during upward flowing; rapid upward flowing of water can be achieved through a certain structure, and finally energy cycle is achieved. The electricity is generated in the process and supplied to people, a beneficial energy cycle of the nature can be achieved, that is, negentropy is achieved on the basis of thermodynamics entropy production, and the frequency of natural disasters on the earth can be reduced finally.

Description

Technical field: [0001] It relates to a method for generating electricity by utilizing low-temperature waste heat of a power plant. Background technique: [0002] At present, the maximum power generation efficiency of thermal power plants is only 42%, and almost more than 60% of the heat generated by coal combustion in thermal power plants is discharged into the atmosphere or the surrounding environment with exhaust steam. This situation not only causes waste of resources, but also causes heat pollution to the environment. In thermodynamics, the ideal gas is in a closed system, and the ideal heat engine efficiency satisfies the calculation formula of (T2-T1) / T2, where T2 is the absolute temperature after heating, and T1 is the ambient heat discharge temperature, because T2 cannot be infinitely increased (temperature After the increase, the pressure of the container cannot stand), or T1 cannot be infinitely reduced (the temperature below the environment that can be discharg...

Problems solved by technology

Therefore, at normal temperature, copper sulfate crystals that have been saturated with water no longer have a strong ability to absorb water, but only have a very general hydration ability. Advantages, the use of "desiccant" substances as materials is no longer very suitable under the structure of "water flowing upwards"
