Device for generating, refrigerating and heat supplying by solar energy and biomass energy

Abstract

The invention provides a device for generating, refrigerating and heat supplying by solar energy and biomass energy, comprising a solar absorption device, a generating device and a biomass high-temperature heating furnace (7). The device is characterized in that an exhaust pipe of a high-energy heat accumulator (2) of the solar absorption device is communicated with the inlet of a first disc-shaped or spiral heating pipe (7.1) arranged in the biomass high-temperature heating furnace (7); and the outlet of the first disc-shaped or spiral heating pipe (7.1) is communicated with an air inlet pipe of a decompressor of a medium-temperature expansion-air motor (4) of the generating device. The device has the advantages that the system ensures that heat energy can be utilized efficiently to reduce exhaust of carbon dioxide; investment and electric energy consumption of refrigerating equipment can be saved simultaneously; the biomass high-temperature heating furnace is connected in parallel when sunlight is not sufficient so as to effectively complement heat energy to ensure that the unit can work continuously; and the device for generating, refrigerating and heat supplying by solar energy and biomass energy has high energy conversion efficiency, and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a solar biomass energy generating refrigeration and heating device. Background technique [0002] Global warming poses a serious challenge to human survival and development. With the continuous growth of global population and economic scale, the environmental problems caused by energy use and their causes are constantly being recognized by people, not only the hazards of smog, photochemical smog and acid rain, but also the global impact caused by the increase in the concentration of carbon dioxide in the atmosphere. Climate change has also been recognized as an indisputable fact. A large part of the carbon dioxide currently produced comes from large-scale thermal power plants. Thermal power plants mainly use coal as fuel. The high-level energy heat of coal fuel is converted into high-temperature and high-pressure water vapor to drive steam turbines to generate e...

AI Technical Summary

Problems solved by technology

A large part of the carbon dioxide currently produced comes from large-scale thermal power plants. Thermal power plants mainly use coal as fuel. The high-level energy heat of coal fuel is converted into high-temperature and high-pressure water vapor to drive steam turbines to generate electricity, and a considerable part Condensation heat is transmitted to the environment, so that the low-level heat energy cannot be fully utilized, and it is not conducive to miniaturization. At the same time, a large amount of carbon dioxide gas is discharged into the atmosphere, which further increases the concentration of carbon dioxide in the human living environment. The rise of the air conditioner has further deteriorated the environment, and a considerable part of the power supply is used in building air conditioners. At present, most of the air conditioners consume electricity, which consumes a lot of electricity, pollutes the environment, and damages the ozone layer. A series of problems , while solar power generation is currently mainly concentrated in the field of solar photovoltaic power generation.
