Problems solved by technology

Some areas rich in geothermal resources have failed to establish geothermal industries with their own characteristics, so that the development of precious geothermal resources remains at a low-level and low-efficiency level, and the phenomenon of resource waste is serious. Natural hot springs in quite a few areas are not fully utilized, and are Waste in vain; some developers do not have a clear understanding of the characteristics of geothermal resources, resulting in the failure of reasonable development and effective protection of geothermal resources

Embodiment Construction

[0011] A same-floor recharge electric heat pump cascade heating system is widely used in geothermal heating. The system is mainly composed of two parts: a heating circulation system and a heating circulation system. It is characterized in that the heating circulation system includes: a water collection pump 1. Water production well 2, plate heat exchanger 3, first valve 4, second valve 5, electric heat pump 6, recharge well 7, third valve 8, fourth valve 9; heating cycle system includes: fifth valve 10. The heat user 11, the sixth valve 12, the seventh valve 13, the eighth valve 14, the ninth valve 15 and the tenth valve 16 are composed of; Water temperature, if the temperature of the geothermal water is lower than 40°C, the geothermal water does not enter the plate heat exchanger 3 to exchange heat with the heating return water, but enters the electric heat pump 6 through the first valve 4 and the second valve 5 to evaporate After the heat exchange, all the low-temperature ge...

Abstract

The invention discloses a same-layer recharge electric heating pump type gradient utilization heating system, and is widely suitable for geothermal heating. The system mainly consists of two parts of a heating circulating system and a heat supply circulating system; the heating circulating system mainly consists of a water picking pump, a water picking well, a plate heat exchanger, a first valve, a second valve, an electric heat pump, a recharge well, a third valve and a fourth valve; and the heat supply circulating system mainly consists of a fifth valve, a heat user, a sixth valve, a seventh valve, an eighth valve, a ninth valve and a tenth valve. Clean and environment-friendly geothermal resources are developed and used; a low-temperature afterheat utilization technology of the electric heat pump is combined to realize deep gradient utilization of geothermal water; and the system is excellent in economic benefit and environmental protecting benefit, and has such advantages as cleanness, environmental protection, universality and applicability.

Description

technical field [0001] The invention relates to a same-floor recharge geothermal heat supply system, in particular to a same-floor recharge electric heat pump type cascade utilization heat supply system. Background technique [0002] Geothermal energy refers to the heat energy stored inside the earth, which comes from the heat emitted by the earth's molten magma and the decay of radioactive elements. Geothermal resources are rock thermal energy, geothermal fluid thermal energy and their associated useful components that can be scientifically and reasonably developed from the crust under the current technical, economic and geological conditions. Energy, etc. are collectively referred to as new energy. Comparing solar energy, wind energy, tidal energy and geothermal energy, geothermal energy is the most realistic energy in new energy. Geothermal resources can be divided into four types according to the form of occurrence: one is hot water type, that is, hot water or water vap...
