Solar methane tank

Abstract

The invention discloses a solar methane tank. A heating circulating box is arranged in the methane tank; a radiator is arranged in the heating circulating box and is connected with a water inlet pipe and a water outlet pipe; a water pump is arranged on a water outlet pipe; the water inlet pipe and the water outlet pipe are connected with a heating device outside the methane tank; a heat-insulating material layer is arranged on the periphery of a methane tank main body; a moistureproof, ratproof and compression-resistant protective layer is arranged outside the heat-insulating material layer; a pressure-bearing heat insulation block is arranged in the heat-insulating material layer on the upper part and lower part of the methane tank; the heating device consists of a solar cell panel, a carbon fiber heating cable, a temperature controller and a temperature detector; the temperature detector is positioned in the center of the methane tank; a carbon fiber heating cable layer is arranged on the periphery of the radiator in the heating circulating box and is communicated to the solar cell panel; the temperature detector feeds temperature back to the temperature controller and provides heat for the methane tank by the carbon fiber heating cable; and the required electric power is provided by the solar cell panel, and circulating water in the heating circulating box also can play a role in temperature reduction under the specific condition.

Description

technical field [0001] The invention relates to the technical field of methane digesters, in particular to solar methane digesters with thermal insulation and heating devices. Background technique [0002] There are many ways to make biogas digesters. There are brick biogas digesters with cement mortar inside and outside, bamboo woven skeleton with cement mortar inside and outside, and inner molds made of steel molds, adding soil while plastering cement. These biogas digesters are not well sealed, waste materials and man-hours, and are of poor quality. Using polyvinyl chloride foam board as the insulation layer, this method uses a lot of earthwork, is easy to be squeezed and deformed, and is easy to be damp, thus affecting the insulation performance. When the biogas digesters in the north are low temperature, they are easy to freeze and cause failure, which affects the use. Contents of the invention [0003] In order to solve the problems existing in the prior art, the o...

These biogas digesters are not well sealed, waste materials and man-hours, and are of poor quality

Use polyvinyl chloride foam board as the insulation layer. This method requires a lot of earthwork, is easy to be squeezed and deformed, and is easy to be damp, which will affect the insulation performance.

When the biogas digester in the north is low temperature, it is easy to freeze and cause failure, which affects the use
