[0022] Example 1

[0023] As attached Figures 1 to 4 The device shown is an integrated device for efficient straw enzymatic hydrolysis fermentation and biochar preparation, including a fermentation tank 1, a spraying component 2, a stirring component 3, a transport component 4, an evaporation component 5, and a carbonization furnace 6.

The carbonization furnace 6 is installed on the side of the evaporation component 5 away from the transport component 4.

[0024] Specifically: when straw enters the fermentation tank 1 through the feed inlet at the top of the fermentation tank 1, the spraying component 2 sprays cellulose-degrading bacteria solution onto the straw to accelerate fermentation, the stirring component 3 can fully mix the straw and cellulose-degrading bacteria solution to promote the enzymatic hydrolysis of the straw, the transport component 4 can transport the fermented straw to the evaporation component 5 for drying, and finally the dried straw will enter the carbonization furnace 6 for carbonization to ultimately form biochar.

[0025] Example 2

[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0027] In a preferred embodiment, the spraying assembly 2 includes a storage tank 7, a spraying pipe 8, and a spraying nozzle 9. The spraying pipe 8 is located below the storage tank 7, and the spraying nozzle 9 is located on the outer diameter surface of the spraying pipe 8. By storing a cellulose-degrading bacteria solution inside the storage tank 7, the straw inside the fermentation tank 1 is sprayed through the spraying pipe 8 and the spraying nozzle 9, so that the cellulose-degrading bacteria can promote the enzymatic decomposition of the straw.

[0028] In a preferred embodiment, the stirring assembly 3 includes a rotating rod 10, a stirring roller 11, a feeding chamber 12, a sealing plate 13, and a sliding chamber 14. The stirring roller 11 is provided on the outer diameter surface of the rotating rod 10, and the feeding chamber 12 is provided below the rotating rod 10. The sliding chamber 14 is provided on one side of the feeding chamber 12, and the sealing plate 13 is slidably arranged inside the sliding chamber 14. After the cellulose-degrading bacteria solution is sprayed, the rotation of the rotating rod 10 and the stirring roller 11 makes the straw inside the fermentation tank 1 fully mixed and contacted with the cellulose-degrading bacteria solution, thereby improving the fermentation efficiency. After fermentation is completed, the sealing plate 13 is pulled to slide inside the sliding chamber 14, so that the fermented straw enters the transport assembly 4 through the feeding chamber 12 for transport.

[0029] In a preferred embodiment, the transport component 4 includes a transport pipe 15 and a first auger 16. The outer diameter surface of the first auger 16 is provided with the transport pipe 15. When the fermented straw enters the transport component 4, the first auger 16 rotates, causing the straw to move forward in the transport pipe 15 and move into the evaporation component 5 for drying.

[0030] In a preferred embodiment, the evaporation assembly 5 includes a drying tank 17, a second auger 18, and heating blocks 19. The drying tank 17 is equipped with the second auger 18 inside, and the outer diameter surface of the drying tank 17 is equipped with heating blocks 19. The second auger 18 drives the straw to move upward, and while moving, multiple sets of heating blocks 19 heat the inside of the drying tank 17 to dry the straw. The dried straw will enter the carbonization furnace 6 through the top pipe for carbonization, and finally form biochar.

[0031] As a preferred embodiment, the spray pipe 8 has a ring structure, and the spray nozzles 9 are arranged in a ring array on the surface of the spray pipe 8. The multiple sets of spray nozzles 9 can spray the inside of the fermentation tank 1 evenly, which not only saves materials, but also makes the spraying more uniform.

[0032] The working process of this utility model is as follows: First, when the straw enters the fermentation tank 1 through the feed inlet at the top of the fermentation tank 1, the spraying component 2 sprays cellulose-degrading bacteria solution onto the straw to accelerate fermentation. The stirring component 3 can fully mix the straw and the cellulose-degrading bacteria solution to promote the enzymatic hydrolysis of the straw. The transport component 4 can transport the fermented straw to the evaporation component 5 for drying. Finally, the dried straw will enter the carbonization furnace 6 for carbonization to form biochar. By storing the cellulose-degrading bacteria solution in the storage tank 7, the straw inside the fermentation tank 1 is sprayed through the spray pipe 8 and spray nozzle 9 to promote the enzymatic hydrolysis of the straw. After the cellulose-degrading bacteria solution is sprayed, the rotation of the rotating rod 10 and the stirring rod 11 makes the straw inside the fermentation tank 1 fully mixed and in contact with the cellulose-degrading bacteria solution, improving the fermentation efficiency. After fermentation is completed, the sealing plate 13 is pulled to slide inside the sliding cavity 14, allowing the fermented straw to enter the transport component 4 through the feeding cavity 12 for transportation.

[0033] After the fermented straw enters the transport component 4, the first auger 16 rotates, driving the straw forward in the transport pipe 15 to the evaporation component 5 for drying. The second auger 18 drives the straw upward, and at the same time, multiple heating blocks 19 heat the inside of the drying tank 17 to dry the straw. The dried straw will enter the carbonization furnace 6 through the top pipe for carbonization, ultimately forming biochar. The above is the working principle of this high-efficiency straw enzymatic fermentation and biochar preparation integrated device.
