Abstract

The invention discloses a biomass organic Rankine cycle power generation system achieving pumped storage regulation. The biomass organic Rankine cycle power generation system comprises a biomass direct combustion hot water boiler subsystem, an organic Rankine cycle power generation subsystem and a pumped storage regulation subsystem. The biomass direct combustion hot water boiler subsystem and theorganic Rankine cycle power generation subsystem are coupled through an evaporator. The organic Rankine cycle power generation subsystem and the pumped storage regulation subsystem are coupled. Electric energy generated by the organic Rankine cycle power generation subsystem can be supplied to domestic and commercial power, and redundant electricity can be used for pumped storage. According to the designed system, in the process of utilizing combustion biomass for heating or centralized heating, energy utilization can be achieved more effectively by additionally mounting the organic Rankine cycle power generation subsystem and the pumped storage regulation subsystem.

Description

technical field [0001] The invention belongs to the technical field of organic Rankine cycle power generation, in particular to a biomass organic Rankine cycle power generation system controlled by pumped storage energy. Background technique [0002] Because of its rich resources, renewable, low pollution and other advantages, the utilization value of biomass energy in human life and social activities continues to increase. According to reports, biomass energy has risen to be the fourth energy after fossil energy coal, oil and natural gas. my country has abundant biomass resources, especially in North China, Central China, and Northeast China. According to estimates, my country's theoretical biomass energy resources are about 5 billion tons of standard coal, which is about four times the current total energy consumption in China. Under the condition of recyclability, the currently available biomass resources in China mainly include crop straw, firewood, domestic garbage, m...
