In order to achieve the above object, the following embodiments will be described in detail with reference to the drawings.

First, as shown in Figures 1 and 2, the structure of the anaerobic double fermentation tank 100 of the present invention is that the secondary fermentation tank 100b is disposed inside the primary fermentation tank 100a, and the secondary fermentation tank 100b is The primary fermentation tank (100a) has a cylindrical closed shape and has a closed shape with a cylindrical first fermentation space (120a) with a predetermined width,

In addition, the volume of the primary fermentation tank 100a may have a volume structure of the first and second fermentation tanks 100a (100b) having a larger volume than the volume of the secondary fermentation tank 100b.

The secondary fermentation tank (100b) is located in the inner center of the primary fermentation tank (100a), that is, the cylindrical secondary fermentation tank (100b) is placed in the inner center of the cylindrical primary fermentation tank (100a), forming the primary fermentation tank (100b). A cylindrical first fermentation space (120a) is formed between the inner circumference of the outer wall (110a) of the secondary fermentation tank (100a) and the outer circumference of the inner wall (110b) of the secondary fermentation tank (100b), while the secondary fermentation tank (100b) has a cylindrical second fermentation space ( 120b) is formed.

And, as shown in Figures 1 and 2, the primary fermentation tank (100a) allows raw materials transferred from an externally placed mixing tank (not shown) to enter the primary fermentation tank (100a) through the first discharge pipe 130. Inflow, approximately 70% to 85% of the raw materials introduced from the primary fermentation tank (100a) are digested, and the fermented product reacts with air-affinity microorganisms among anaerobic microorganisms through horizontal stirring to produce 1 It is located at the top of the primary fermentation tank (100a), and on the contrary, the fermented product produced by reacting with microorganisms that have no affinity for air is located at the bottom of the primary fermentation tank (100a), so that the fermented product within the primary fermentation tank (100a) is divided into fermentation layers.

By the operation of the inclined rotating shaft, the fermented product is moved within the first fermentation space (120a). At this time, the fermented product is formed through a horizontal stirring process while rotating within the cylindrical first fermentation space (120a). do.

And, as shown in Figure 1, the secondary fermentation tank (100b) is a fermented product produced from the primary fermentation tank (100a) through the second discharge pipe due to the water level difference between the first and secondary fermentation tanks (100a) (100b). It flows into the second fermentation space (120b) through (140) and undergoes secondary fermentation to produce digested product, and the fermented product introduced from the primary fermentation tank (100a) is vertically stirred by the second stirrer for a predetermined time. Biogas is generated by decomposing and fermenting harmful substances while remaining through them, and the fully fermented digest of the fermentation broth is passed through a separate third discharge pipe (150) with an overflow type discharge structure installed at the bottom of the secondary fermentation tank (100b). It is transported to the digestion tank (not shown).

And, as shown in Figures 1 and 2, it has a structure in which sediment is discharged through a sediment collection unit 160 in which sediment falls and is collected on a portion of the bottom surface of the primary fermentation tank 100a.

Among the fermented products that are horizontally stirred in the first fermentation space (120a) of the primary fermentation tank (100a), the sediment that falls due to the difference in specific gravity is collected, so that a more homogeneous fermented product is stored in the first fermentation space (120a) of the primary fermentation tank (100a). 120a) to allow fermentation, and the sediment collection unit 160 is located on one side of the bottom located at the bottom of the inner circumference of the outer wall (110a) of the primary fermentation tank (100a) to the bottom of the outer circumference of the inner wall (110b) of the second fermentation tank (100b). It has a structure formed in the form of a square groove with a predetermined width in a straight line to the other side of the bottom surface where it is located. When sediment is received, the sediment collection unit 160 is immediately forced to discharge to the outside through a discharge means such as a pump or undergoes first fermentation.
