Geothermal energy central heating system based on electric heat pump unit

Abstract

The invention provides a geothermal energy central heating system based on an electric heat pump unit. The system involves a heat supply initial station steam-water heat exchanger and a geothermal energy heat exchange unit, wherein a steam side inlet of the heat supply initial station steam-water heat exchanger is connected with a steam exhaust port of a medium-pressure cylinder; a water side outlet of the heat supply initial station steam-water heat exchanger is connected with a heat supply network water supply pipeline; a water side inlet of the heat supply initial station steam-water heat exchanger is connected with a water side outlet of the geothermal energy heat exchange unit; a water side inlet of the geothermal energy heat exchange unit is connected with a heat supply network water return pipeline; and an outlet and an inlet of the geothermal energy heat exchange unit are connected with a geothermal water return pipeline and a geothermal water inlet pipeline respectively. According to the system, on one hand, comprehensive utilization of geothermal energy is promoted, and the industrial structure is optimized; and on the other hand, carbon emission is reduced, haze pollution is relieved, and clean heating is promoted.

Description

technical field [0001] The invention belongs to the field of cogeneration of heat and power, and relates to a geothermal energy centralized heating system based on an electric heat pump unit. Background technique [0002] In recent years, the emergence of problems such as aggravated smog and the depletion of fossil energy have led to a new upsurge in the application of clean and renewable energy. As a very important clean energy, geothermal energy was once neglected. China's geothermal resources account for one-sixth of the world's total. However, the degree of development and utilization of geothermal resources is relatively low at present, and the existing mature geothermal development technologies generally have utilization rates. Not high flaws. In addition, most of the centralized heat supply in northern my country uses cogeneration units as the main heat source, and the energy industry has a single organization. Carbon challenge. Contents of the invention [0003] ...
