Thermoelectric city heat supply distribution type energy storing and peak adjusting heat supply system

Abstract

The invention provides a thermoelectric city heat supply distribution type energy storing and peak adjusting heat supply system. The thermoelectric city heat supply distribution type energy storing and peak adjusting heat supply system at least comprises a thermal power plant unit (1), a heat supply unit (2), a phase changing heat storing water tank (3), a plate type heat exchanger (4), a terminaldraught fan coil pipe (5), a temperature monitor (6), a heat supply circulating water pump (7), a pressure monitor (8), a non-return valve (9), a phase changing energy storing material (10), an electric heater (11), a pipeline circulating water pump (12) and an expanding tank (13). The thermoelectric city heat supply distribution type energy storing and peak adjusting heat supply system is characterized in that the thermal power plant unit (1) and the phase changing heat storing water tank (3) form a heat storing circulating loop; heat supply hot water of a thermal power plant is fed into thephase changing heat storing water tank (3) through the pipeline circulating water pump (12), and the expanding tank (13) is installed on a pipeline; the phase changing heat storing water tank (3) andthe plate type heat exchanger (4) form a heat supply heat exchanging loop, and the electric heater (11) is additionally arranged in the phase changing heat storing water tank (3); heat is delivered into the terminal draught fan coil pipe (5) through the heat supply circulating water pump (7), and the temperature monitor (6) and the pressure monitor (8) are additionally arranged in a pipeline to provide data; and when heat supply of the thermal power plant unit (1) is sufficient, redundant heat is stored in the phase changing energy storing material (10), and when heat supply of the thermal power plant unit (1) is insufficient, the phase changing energy storing material (10) is used for providing an auxiliary heat source.

Description

technical field [0001] The invention relates to a thermoelectric urban heating distributed energy storage peak-shaving heating system, which belongs to the field of efficient energy utilization technology and peak-shaving and valley-filling. Background technique [0002] Energy is becoming more and more important in the process of rapid economic development in our country. Energy conservation and emission reduction in the construction field are being vigorously promoted and constructed. Energy consumption and energy conservation for heating and heating are very critical. Thermal power plants are not only large energy consumers, but also large pollutant emitters. It is very important to improve the energy utilization efficiency of power plants. [0003] In order to improve energy utilization efficiency and promote energy utilization in thermal power plants, after the fuel is released in the boiler, the heated water vapor enters the steam turbine to generate power, and the ste...
