specific Embodiment approach 1

[0016] Specific implementation mode one: combine figure 1 To illustrate this embodiment, this embodiment includes a fermenter body 1, a dehumidifier 2, a gas booster pump 3, a gas circulation pipeline 4 and a plurality of nozzles 5;

[0017] The fermentation tank body 1 forms a certain angle α with the horizontal plane, and the fermentation tank body 1 is provided with a discharge port 1-1, a feed port 1-2, an air outlet 1-3 and a gas collection port 1-5, and a feed port 1- 2 and the discharge port 1-1 are provided with valves, the gas collection port 1-5 is provided with a gas collection device 6, one end of the gas circulation pipeline 4 is connected with the gas outlet 1-3, and one end of the gas circulation pipeline 4 extends into the fermentation Inside the tank body 1 , a plurality of nozzles 5 are provided on the gas circulation pipeline 4 extending into the fermentation tank body 1 , and a dehumidifier 2 and a gas booster pump 3 are provided on the gas circulation pipe...

specific Embodiment approach 2

[0018] Specific implementation mode two: combination figure 1 To illustrate this embodiment, the angle α between the fermenter body 1 and the horizontal plane in this embodiment is 3°-5°.

[0019] Such setting is to ensure that the material is stirred evenly, and at the same time, the material is moved downward for a certain distance, so that the fermented waste is discharged through the discharge port 1-1, and at the same time, the waste fermented material will not be fermented. The storage in the tank body 1 better guarantees the effect of fermentation.

[0020] Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0021] Specific implementation mode three: combination figure 1 To illustrate this embodiment, the fermenter body 1 in this embodiment is a cylindrical tank body, and the ratio of its diameter to length is 1:4 or 1:5.

[0022] Such setting is to improve the plug flow effect, so that the material is discharged from the outlet 1-1 of the fermenter body 1 in the form of air blowing.

[0023] Other compositions and connections are the same as in the first embodiment.

[0024] Specific implementation mode four: combination figure 1 To illustrate this embodiment, the gas circulation pipeline 4 extending into the fermentation tank body 1 described in this embodiment is arranged parallel to the centerline of the fermentation tank body 1, and the gas circulation pipeline 4 extending into the fermentation tank body 1 is set 1 / 3 below the centerline of the fermenter body 1.

[0025] This setting is to keep a certain distance between the air nozzle and the material, so that the materia...

Abstract

The invention discloses a gas circulating and stirring plug-flow type anaerobic fermentation reaction device, relates to a biological fermentation device, and solves the problems that the operation energy consumption of current anaerobic fermentation of livestock and poultry feces is high, the feeding concentration is low in the plug-flow type anaerobic digestion process, the mass transfer of thematerial is poor, and the precipitating and the layering are caused easily. The gas circulating and stirring plug-flow type anaerobic fermentation reaction device comprises a fermentation tank body, adehumidifier, a gas booster pump, a gas circulating pipeline and a plurality of air faucets; a certain included angle is formed between the fermentation tank body and the horizontal plane, a discharge opening, a feed opening, a gas outlet and a gas collecting opening are formed in the fermentation tank body, valves are arranged on both the feed opening and the discharge opening, a gas collectingdevice is arranged in the gas collecting opening, one end of the gas circulating pipeline is connected with the gas outlet, one end of the gas circulating pipeline extends into the fermentation tank body, a plurality of air holes are formed in the gas circulating pipeline extending into the fermentation tank body, a spray nozzle is arranged on each air hole, and the dehumidifier and the gas booster pump are arranged on the gas circulating pipeline on the outer part of the fermentation tank body. The gas circulating and stirring plug-flow type anaerobic fermentation reaction device is suitablefor biological fermentation.

Description

technical field [0001] The invention relates to a biological fermentation device, in particular to a gas circulation stirring plug flow type anaerobic fermentation reaction device. Background technique [0002] Anaerobic fermentation refers to a complex biochemical process in which organic matter, such as livestock and poultry manure, straw, sludge, etc., is degraded by microbial communities under anaerobic conditions, gradually decomposed and transformed, and finally produces biogas. The main components of the gas are methane and carbon dioxide. [0003] Anaerobic digestion technology processes biomass for energy utilization. While providing clean energy biogas, it also solves the problem of environmental pollution caused by random stacking of biomass, and fermentation residues such as biogas residues and biogas liquids can also be used for agricultural purposes. Produced high-quality organic fertilizers, so that biomass resources can be used multiple times and comprehensi...
