A combined cooling, heating and power generation system with complementary integration of solar energy and biomass

Abstract

The invention discloses a combined cooling, heating and power generation system with complementary integration of solar energy and biomass. The system includes a biomass preheater, a biomass pulverizer, a bubbling fluidized bed gasifier, a cyclone separator, and First heat exchanger, second heat exchanger, condenser, air separation unit, water pump, trough solar collector, internal combustion engine generator set, single-effect hot water type absorption unit, third heat exchanger and solution absorption dehumidification unit. The invention integrates the renewable energy of biomass and solar energy, and through the complementary integration of different energy sources, the total energy system efficiency of the system is as high as 70.1%, which is of great significance for optimizing the energy mechanism at the input end and sustainable development of the environment.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a three-generation system of cooling, heating and power combined with complementary integration of solar energy and biomass. Background technique [0002] The energy issue is a common concern of the whole world and even all mankind. It not only refers to energy itself, but is related to climate change and environmental protection, and is related to people's livelihood, economic development and national security. With the consumption of fossil energy such as coal and oil, the originally balanced energy cycle is destroyed. While burning fossil energy to release energy, a large amount of carbon is released, breaking the ecological balance. The amount of carbon dioxide released by the burning of fossil energy has far exceeded the absorption capacity of green plant photosynthesis. A series of phenomena such as ozone layer depletion and climate anomalies brought along with it have mad...

AI Technical Summary

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 raw material source, and the energy input is not diversified, and there is no real meaning to achieve multiple Energy complementarity and moderate and deep application

2) The output products of the biomass cogeneration system are single, mainly heat and power products, and the application of cooling, heating and power, and even dehumidification is less, which cannot meet the diversified energy needs of end users at the same time
