Energy-saving full-automatic multifunctional arranged biogas digester and working method thereof

Abstract

The invention relates to an energy-saving full-automatic multifunctional arranged biogas digester and a working method thereof. The energy-saving full-automatic multifunctional arranged biogas digester comprises a tank body horizontally lying underground, the interior of the tank body is divided into a plurality of fermentation chambers through partition plates, a central rotating shaft penetrating through the partition plates is arranged in the tank body in the axis direction of the tank body, stirring impellers used for stirring, propelling and collecting and pressing biogas slurry and residues are arranged on the central rotating shaft and located in each fermentation chamber, the left end of the tank body is connected with a digester body with a water pressure room serving as a feeding port, an automatic feeding driving mechanism is arranged on the digester body, an automatic residue discharging mechanism is arranged at the right end of the tank body, and a biogas storage and output mechanism is arranged at the upper part of the tank body; and the central rotating shaft, the driving mechanism and the automatic residue discharging mechanism are operated by an automatic cycle time relay to operate a motor for several times every day to complete the whole implementation process. According to the biogas digester, nutrients in the biogas slurry can be fully utilized and converted into biogas, and the gas production rate is increased by about 50%.

Description

Technical field [0001] The present invention relates to an energy-saving automatic multi disposed digesters and working methods. Background technique [0002] To achieve our commitment to the World Climate Summit reduction targets and tasks to the world in many areas to promote the use of biogas as a fuel source for residents in their daily lives and solve faecal contamination of water, the environment, but because raising livestock manure biogas little less inadequate material, if high-wage workers spend marsh to obtain additional material to supplement, rather that the liquefied gas or electricity more cost-effective and convenient, since conventional digesters low gas production reasons, the utilization rate is not high, such as raising 6 pigs manure for biogas production 5 normal people use, it is raised only three can be designed to improve the yield if 50% of the digester gas to solve, which is the original intention of the present application, and therefore a need for an e...

Problems solved by technology

[0002] In order to realize the emission reduction goals and tasks my country promised to the world at the World Climate Summit, many regions promote the use of biogas as a source of fuel for residents’ daily life and to solve fecal pollution of water sources and the environment. It is more cost-effective and convenient to use electricity or liquefied petroleum gas to obtain other biogas to supplement. The existing biogas digesters have low utilization rate due to low gas production and other reasons. For example, raising 6 pigs to produce biogas can supply 5 People use it normally, and now they only raise 3 pigs. Can we design a biogas digester that increases the gas production by 50%?
