Problems solved by technology

The utilization of the above-mentioned heat sources is in full swing in the development and utilization of clean energy, all of which have good social and environmental benefits, but at the same time encounter some problems, such as: when using solar energy for heating, due to the limitation of the lighting area, the heating capacity is insufficient, At the same time, in the non-heating season, solar energy resources are more abundant but cannot be fully utilized, resulting in a large amount of energy waste and idle equipment; if the heat energy in the middle and deep layers is not fully replenished, there will be a certain degree of attenuation, and industrial waste heat and waste heat also have the problem of imbalance between supply and demand.

Abstract

The invention relates to a system for storing heat through a middle-deep-strata geothermal well. The system comprises a heat energy collecting element, a heat energy exchanger, a middle-deep-strata geothermal heat exchanger arranged in the middle-deep-strata geothermal well and a control system; the heat energy collecting element is connected with the heat energy exchanger through a heat exchangecirculating pipeline I; the heat energy collecting element is connected with the heat energy exchanger through a heat exchange circulating pipeline II by means of a heat exchange circulating pump; theheat energy exchanger is connected with the water inlet side of the middle-deep-strata geothermal heat exchanger through a heat storage circulating pipeline I by means of a control valve I; the heatenergy exchanger is connected with the water outlet side of the middle-deep-strata geothermal heat exchanger through a heat storage circulating pipeline II by means of a heat storage circulating pumpand a control valve II in sequence; the heat exchange circulating pipeline I and the heat storage circulating pipeline I are each provided with a temperature control probe; and the temperature controlprobes, the heat exchange circulating pump, the heat storage circulating pump, the control valve I and the control valve II are all connected with the control system. The system is simple in configuration and low in running power dissipation and is a novel and environment-friendly heat energy storage and utilization mode.

Description

technical field [0001] The invention relates to the field of energy utilization, in particular to a heat storage system utilizing medium-deep geothermal wells. Background technique [0002] With the development of my country's social economy, heating energy consumption is increasing day by day, and green, clean and renewable energy heating has also become the mainstream. Currently, clean heat sources that can be used for heating or hot water supply include solar energy, geothermal energy, and industrial waste heat. In the composition of my country's building energy consumption, HVAC energy consumption accounts for about 60% of the total energy consumption. This part of the energy consumption structure is still dominated by fossil energy, which has aggravated the degree of air pollution in our country. Therefore, for the heating industry, renewable energy, especially solar energy and geothermal energy, have been highly concerned by the Chinese government and widely used. How...
