Abstract

A dry fermentor of marsh gas and its warming method for continuously feeding raw materials and discharging dregs features that a deep pit is dug in the ground, a dry fermentor for generating marsh gas in it, the straw or stalk is filled in the space between said fermentor and pit walls, and a solar heat collector is used to cover on the top of fermentor.

Description

Technical field: [0001] The invention relates to a device for continuously feeding and discharging biogas dry fermentation and a method for increasing heat preservation, which belongs to a device for providing clean and renewable energy by continuously feeding and discharging biogas through dry fermentation using crop orange stalks, degradable domestic garbage and human, livestock and poultry feces as raw materials. And implement solar energy and biological energy to increase heat preservation treatment method to this device. Background technique: [0002] At present, biogas is mostly produced by low-concentration fermentation devices in cement ponds, and the four-in-one type is promoted in the north. It is not possible to continuously feed and discharge materials, but only intermittently, and it is easy to form a scum layer, which makes it difficult to mix and discharge materials. The cement pool is built underground, and due to the low ground temperature, the pool tempera...
