Embodiment Construction

[0023] The purpose of the present invention is to provide a combined biogas underground heat storage system. The biogas pool is used to set up the underground heat storage unit at the same time. The biogas pool protects the heat storage unit and collects heat. The heat storage unit releases heat to promote the reaction of the biogas pool. achieved better results.

[0024] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following specific embodiments will further describe the present invention in detail.

[0025] Embodiment 1 provides a biogas underground heat storage combined system, including a heat collection unit, which uses solar energy to collect heat, and the solar heat collection tube is installed on the top or side light-receiving surface of the building to convert solar energy into heat energy. At the same time, an underground heat storage unit is arranged under the building, and the underground...

Abstract

The invention discloses a solar energy and biogas combined heat storage system, and relates to the field of new energy. The solar energy and biogas combined heat storage system comprises a heat collecting unit, an underground heat storage unit and a biogas generating device, wherein the heat collecting unit is used for collecting external energy and converting the external energy into heat energy;the underground heat storage unit is used for storing the heat energy collected by the heat collecting unit underground through water in a heat storage tank; the biogas generating device is arrangedaround the underground heat storage unit; and/or the biogas generating device is arranged in the underground heat storage unit. Through the structural arrangement, the heat preservation effect of theheat storage tank is improved, meanwhile, a good temperature environment is provided for fermentation of a biogas digester, solar energy and biogas supplement each other, and an unexpected applicationeffect is achieved.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a solar biogas combined heat storage system. Background technique [0002] Solar energy is the cleanest energy, its light-to-heat conversion rate can reach more than 80%, and in the process of use, except for the equipment manufacturing process, no carbon emissions are generated, and the "reserve" of light energy is unlimited. But in summer, the temperature is high and the sun is abundant, the amount of solar energy that can be converted into heat is large, but the demand for heat is very small. With the help of special solar heat collection house structure, the solar heat storage system is used to store the excess heat in summer and use it in winter. is an effective method. (Patent 2018206804185 discloses a storage and utilization method). The main technical point of this solar energy utilization method is to improve the heat storage efficiency of the underground space and reduce the...
