Automatic-batching straw biogas digester

Abstract

The invention discloses an automatic-batching straw biogas digester. The automatic-batching straw biogas digester comprises a thermal insulation room, a water collection box, an electric heating tube, an anaerobic tank, a solar heat collector and a controller. The thermal insulation room is provided with a light-permeable vertical window. The inner wall of the thermal insulation room is provided with a heat storage layer for heat storage. A heat conduction plate is arranged in the water collection box. The water collection box is divided into an inner box and an outer box through the heat conduction plate. The electric heating tube is arranged between the inner box and the outer box. The electric heating tube is communicated with an output end of the controller. The anaerobic tank is arranged in the thermal insulation room. The inner wall of the anaerobic tank is provided with a thermal insulation layer for thermal insulation. A temperature sensor and a heating coil are arranged in the anaerobic tank. The temperature sensor is communicated with an input end of the controller. The solar heat collector is arranged above the thermal insulation room. The solar heat collector, a first pump and the inner box are orderly connected through pipes so that a first circulating loop is formed. The inner box, a second pump and the heating coil are orderly connected to form a second circulating loop. The anaerobic tank is provided with a fermentation feeding system.

Description

technical field [0001] The invention relates to the field of biogas, in particular to a straw biogas digester with automatic batching. Background technique [0002] At present, in the treatment of domestic waste, the more difficult ones mainly include organic waste and human excrement. Generally, organic waste includes sink waste and food waste. Sink waste is generally produced by food residues and vegetable and fruit peels entering the sewage pipe from the sink. This type of waste is difficult to recycle and is also prone to blockage of pipes. ; Food waste generally includes vegetable and fruit peels and food residues thrown into the trash can. This kind of garbage is easy to produce stench when placed in the open air, and because of its high water content, the cost of incineration or landfill treatment is too high. Generally, human excrement is directly passed into septic tanks, and after simple treatment, it is directly passed into rivers. In this way, more harmful micro...
