Description

Split type methane-generating pit Technical Field The invention relates to the technical field of biomass energy utilization equipment, in particular to a split type methane tank. Background The biogas digester is used as core equipment for converting organic wastes into clean energy (biogas) and organic fertilizer (biogas slurry and biogas residue), and plays an important role in rural energy transformation and ecological agriculture development. The existing biogas digester has obvious technical limitations and restricts popularization and application thereof: The structure is integrated, the functions are mutually interfered, namely, the traditional biogas Chi Duowei 'fermentation-gas storage-liquid storage' integrated structure is used for mixing and storing biogas, biogas slurry and biogas residue generated in the fermentation process, so that the purity and the collection efficiency of the biogas are affected, the cleaning and the discharge of the biogas slurry and the biogas residue are difficult, and the tank body is easy to be blocked. The fermentation efficiency is low, the gas production is unstable, the organic materials are unevenly mixed in the tank body, the high-efficiency stirring device is lacked, so that microorganisms are not fully contacted with the materials, the fermentation temperature is greatly influenced by the environment, the fermentation rate is greatly reduced in the low-temperature environment, and the gas production stability is poor all year round. The biogas slurry and the biogas residue after fermentation are not effectively separated, the biogas residue is easy to block a pipeline when being directly discharged or used, and the biogas residue is not classified to cause resource waste, so that the recycling requirement of ecological agriculture is not met. The maintenance operation is complicated, the biogas digester with an integrated structure needs to be shut down and emptied, the operation difficulty is high, the labor intensity is high, and the potential safety hazard exists, so that the maintenance is difficult to be independently completed by common farmers, and the split biogas digester is provided. Disclosure of Invention In view of this, the present invention provides a split biogas digester to solve or alleviate the technical problems existing in the prior art, at least providing a beneficial option. The technical scheme is that the split type biogas digester comprises a tank body, a gas storage tank and a biogas slurry tank, wherein the gas storage tank is arranged on the left side of the tank body, the biogas slurry tank is arranged on the right side of the tank body, a gas pipe is communicated between the tank body and the gas storage tank, a discharging pipe is communicated with one side of the tank body, one end of the discharging pipe is communicated with a slag-liquid separator, a liquid outlet end of the slag-liquid separator is communicated with a liquid conveying pipe, and one end of the liquid conveying pipe is communicated with the biogas slurry tank. Further preferably, an underground heating furnace is arranged at the bottom of the tank body. Further preferably, one end of the slag-liquid separator is communicated with a slag discharging pipe. Further preferably, a plurality of motors are uniformly arranged at the top of the tank body, the output ends of the motors are fixedly connected with stirring rods, and a plurality of stirring blades are uniformly and fixedly connected with the outer side walls of the stirring rods. Further preferably, a feed inlet is formed in one side of the tank body. Further preferably, the discharging pipe, the infusion pipe and the slag discharging pipe are all provided with independent valves for controlling material conveying. Further preferably, a pressure gauge and a safety valve are arranged on the air storage tank and are used for monitoring the air pressure in the tank and realizing overpressure pressure relief.
