A cascade utilization enhanced geothermal system (egs)

Abstract

The invention relates to the technical field of geothermal systems, in particular to an enhanced geothermal system (EGS) capable of cascading comprehensive utilization of geothermal energy, improving utilization of geothermal energy, and saving energy, especially an enhanced geothermal system (EGS) for cascaded utilization. Including geothermal collection device, first-level heat exchange device, first-level utilization device, second-level heat exchange device, second-level utilization device, third-level heat exchange device, third-level utilization device, capillary network system, temperature control device, water collection tank and geothermal energy Recharging device. This system uses geothermal energy as a heat source, which is clean and renewable; cascade comprehensive utilization of geothermal energy can be carried out to improve the utilization rate of geothermal energy and save energy; the heat exchange device is equipped with a screw pump to improve heat exchange efficiency; fixed trays and movable trays in the warehouse Fruits and vegetables can be fixed, and the drying process is accelerated under the drive of the rotating rod. There is a layered capillary network system in the warehouse, which is conducive to the uniform heating and drying of crops.

Description

technical field [0001] The invention relates to the technical field of geothermal systems, in particular to an enhanced geothermal system (EGS) capable of cascading comprehensive utilization of geothermal energy, improving geothermal utilization, and saving energy, especially an enhanced geothermal system (EGS) for cascaded utilization. Background technique [0002] In the season of vegetable harvest, once there is a problem of slow sales or continuous rainy weather, a large number of vegetables will rot because they cannot be kept fresh, causing considerable economic losses to farmers. For this reason, farmers can dry and dehydrate vegetables to make dried vegetables for sale. The dehydrated vegetable processed products have low water content, which can effectively inhibit the activity of microorganisms and enzymes in the tissue, so the storage period is prolonged, and the volume and weight are reduced, which is convenient for storage and transportation. Usually, the moist...

Problems solved by technology

Coal burning will pollute the environment; although fuel oil is an energy source, it also emits pollutants of different magnitudes, the cost of use is high, and it has no promotion value

[0006] The use time of the grain dryer is limited. It can only be used for dozens of days a year during the busy farming season, and it can only be idle at other times, resulting in waste of resources, low return on investment, and difficult promotion.

[0007] At present, the crop drying equipment on the market often only has the drying function. After the crops are dried, they need to be transferred and stored in the granary. During the transfer process, the moisture in the air will be sucked in, resulting in mildew and germination in the granary.
