Abstract

The embodiment of the invention provides a terrestrial heat and thermal power plant coupled multi-stage heat supply system which comprises a heat pump set, a stratum heat collection system and a heat supply system. Each of the stratum heat collecting system and the heat supply system is connected with the heat pump set so that heat of the stratum heat collecting system can be transmitted to the heat supply system through the heat pump assembly. Therefore, the terrestrial heat and thermal power plant coupled multi-stage heat supply system has the advantages of being good in heat continuity and free of pollution, consumption of coal in the heat supply system is reduced to a certain extent, and heat supply carbon emission is reduced.

Description

technical field [0001] The invention relates to the technical field of geothermal development and utilization, in particular to a multi-stage heating system coupled with geothermal and thermal power plants. Background technique [0002] Geothermal is a kind of renewable energy, which is basically not affected by weather and seasonal changes, and has the advantages of stable and continuous energy supply and high utilization rate. Through the geothermal heat source, high-temperature water of about 60-80 °C can be extracted for heating. In related technologies, coal accounts for nearly 80% of the urban heating energy in my country. Coal itself is a non-renewable resource, and coal heating also has the problem of high pollution. SUMMARY OF THE INVENTION [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, an embodiment of the present invention proposes a multi-stage heating system coupled wit...
