Water source heat pump-steam turbine and heat supply network complementary combined heating supply system

Abstract

The invention provides a water source heat pump-steam turbine and heat supply network complementary combined heating supply system. The heating supply system comprises a steam boiler, a steam turbine, a steam condenser, a peak heat supply network heater, a heat exchange station, a heat consumer, a dirt cleaner and a boiler water feed pump and further comprises a water source heat pump, a supply water pump, a network circulating water pump, a heat supply network water supply pipeline and a heat supply network water return pipeline. According to the water source heat pump-steam turbine and heat supply network complementary combined heating supply system provided by the invention, underground water renewable energy and exhaust-steam waste heat are fully used, the energy conversion link in the heat supply process of the water source heat pump is reduced, and thus the stability and heat efficiency of the heating supply system are improved. The heating supply system form suitable for the northeast severe cold area is improved, and economy, environmental protection, energy conservation and emission reduction of distributed type heat supply are achieved.

Description

technical field [0001] The invention relates to the technical field of heat supply, in particular to a water source heat pump-steam turbine and heat network complementary combined heat supply system. Background technique [0002] In the severe cold area of ​​Northeast my country, the heating energy consumption in winter is large, and the centralized heating method mainly adopts coal-fired boilers, resulting in a huge waste of energy and serious environmental pollution. Moreover, with the continuous acceleration of my country's urbanization process, the original central heating system is far from being able to meet the increasing heating demand. On the other hand, in today's severe energy shortage, high-efficiency heating systems using renewable energy such as water source heat pumps have received widespread attention and vigorous development, and the use of renewable energy has become an effective means to alleviate the current energy situation. However, the tense power pro...

AI Technical Summary

Problems solved by technology

However, due to the low temperature of the circulating cooling water in the steam condenser, it cannot meet the quality requirements of direct heating, so it cannot be directly used in the heating system under normal circumstances.

This not only causes waste of energy, but also brings thermal pollution to the environment.
