Abstract

The invention relates to a biogas digester structure adopting geothermal heating. The biogas digester structure comprises a biogas digester, a feeding cavity and a discharging cavity, wherein the feeding cavity and the discharging cavity are located on the two sides of the biogas digester and communicate with the inner side of the biogas digester; sealing cover plates are arranged on the feeding cavity and the discharging cavity; a sealing top is installed on the inner side of the biogas digester through a movable assembly; the sealing top is connected with an air outlet pipe; a second sleeveis rotatably installed on the side, facing the inner side of the biogas digester, of the sealing top; the second sleeve is connected with a driving mechanism installed on the sealing top; the end, away from the driving mechanism, of the second sleeve is inserted into a driving pipe and is in sliding fit with the driving pipe; the end, far away from the second sleeve, of the driving pipe is connected with a first sleeve rotationally installed at the bottom of the biogas digester; and the first sleeve is in sliding fit with the driving pipe. The problem that an existing biogas digester structureis low in biogas generation efficiency due to the poor heating effect is effectively solved.

Description

technical field [0001] The invention relates to the related technical field of geothermal utilization, in particular to a methane pool structure using geothermal heating. Background technique [0002] Geothermal energy is the natural thermal energy extracted from the earth's crust. This energy comes from the lava inside the earth and exists in the form of heat. It is the energy that causes volcanic eruptions and earthquakes. [0003] The temperature inside the Earth reaches as high as 7,000°C, and at depths of 80 to 100 kilometers, the temperature drops to 650 to 1,200°C. Heat is transferred closer to the ground through the flow of groundwater and lava pouring into the crust 1 to 5 kilometers above the ground. The hot lava heats nearby groundwater, which eventually seeps out of the ground. The easiest and most cost-effective way to harness geothermal energy is to take these heat sources directly and extract their energy. [0004] Biogas digesters are used to treat domesti...
