A combined cooling, heating and power system based on biomass gasification and solar heat utilization

Abstract

The invention discloses a Combined Cooling Heating And Power (CCHP) system based on biomass gasification and solar energy heat utilization; the CCHP system comprises a biomass belt type drying machine, a biomass pulverizer, a fixed bed gasification furnace, an electric precipitator, a first heat exchanger, a condenser, an air diverter, a water pump, a slot type solar heat collector, a gas turbine, a steam type absorption unit, and a second heat exchanger; the CCHP system combines two renewable energy sources including biomass and solar energy, can realize advantage complementation of said two energies, and can realize gradient utilization of waste heat resource of the combined production system, thus realizing energy reasonable utilization and distribution. The CCHP system can have the total energy efficiency to be above 65.9%, can optimize energy composition, can protect environment, and can reduce pollutant discharge, thus realizing energy sustainable development.

Description

Technical field [0001] The invention relates to the field of energy technology, in particular to a cogeneration system based on biomass gasification and solar thermal utilization. Background technique [0002] Energy, as the material basis of human activities, has always received extensive attention. In a sense, the development of human society cannot do without energy. As the demand for energy consumption continues to increase and resource constraints are intensified, sustainable development is facing challenges. With the consumption of fossil energy such as coal and petroleum, while fossil energy is burning to release energy, its environmental impact has attracted increasing attention. The pollution of the atmosphere and the impact on the global environment have become the object of attention of all countries. Therefore, the development of renewable energy is of great significance for dealing with the pollution problem of fossil energy. Among them, solar energy and biomass e...

Problems solved by technology

[0006] The main problems in the current research on the existing design concept and implementation plan of the biomass cogeneration system are: 1) The biomass cogeneration system uses biomass as the main source of raw materials, and the use of renewable energy is single, and there is no real meaning to achieve multiple Energy comprehensive complementarity and deep application

2) The output products of the biomass cogeneration system lack diversity, mainly heat and power products, and the application of cold and heat power is less, and the output of energy products is single
