Embodiment 1

[0025] First, dig a deep pit on the ground. The length, width, and depth of the pit are 2 meters away from the periphery of the dry fermentation device as an isolation layer. The bottom of the dry fermentation device is placed on a base 0.5 meters from the bottom of the pit to cut off the influence of ground temperature on the dry fermentation device. ; The stone walls around the isolation layer and the bottom are buried with foam plastic boards at a depth of 1 meter, and the thickness of the boards is 10 cm, to further isolate the influence of ground temperature; Warm water bed, the diameter of the pipe is 20 cm, the length is 25 meters, and a total of 10 pipes are laid; the laid pipes are backfilled with sand or original soil as energy storage materials for solar energy; the backfilled sand and original soil are covered with heat preservation Materials; add multiple solar greenhouse heat collectors on the surface 1 meter away from the mouth of the pit.

Embodiment 2

[0027]First, dig a deep pit on the ground. The length, width, and depth of the pit are 3 meters away from the periphery of the dry fermentation device as an isolation layer. The bottom of the dry fermentation device is placed on a base 1 meter away from the bottom of the pit to cut off the influence of ground temperature on the dry fermentation device. ; The stone walls around the isolation layer and the bottom are buried with foam plastic boards at a depth of 1 meter, and the thickness of the boards is 10 cm to further isolate the influence of the ground temperature; Warm water bed, the diameter of the pipe is 30 cm, the length is 300 meters, 15 pipes are laid in total; sand and gravel or raw soil are backfilled on the laid pipes as energy storage materials for solar energy; Materials; add multiple solar greenhouse heat collectors on the surface 2 meters away from the mouth of the pit. In winter in the north, fill the thermal insulation material with yellow storage corn stalk...

Abstract

A continuous and automatic dry marsh-gas feeding and discharging fermenter, its process and temperature-maintaining and raising method are disclosed. The procedure is carried out by digging dell on ground, putting dry marsh-gas fermenter into dell underground, which is buttering, filling it with corn straw on its thermal-insulating material in winter of northern China, sealing, aerobic and anaerobic fermenting, temperature raising and maintaining, and spreading anaerobic fermenting ventilating pipeline at 1 / 3 of anaerobic temperature-raising pool, covered with multiple solar greenhouse heat collector. It is simple and rational and finishes feeding and discharging synchronously.

Description

Technical field: [0001] The invention relates to a continuous automatic feeding and discharging biogas dry fermentation device, process and heat preservation method, which belong to crop orange stalks, degradable domestic garbage and human, livestock and poultry manure as raw materials for continuous dry fermentation to generate biogas to provide clean regeneration Energy device, and implement the solar energy and biomass energy increasing heat treatment method on the device. Background technique: [0002] At present, biogas is mostly produced by low-concentration fermentation devices in cement ponds. The four-in-one biogas digester is promoted in the north, which is easy to form a scum layer, making it difficult to mix and discharge materials. The cement pool is built underground, and due to the low ground temperature, the pool temperature is also low. The climate in northern my country is cold, and the ground temperature is lower. Even if the "four-in-one" formula is adop...
