Description

Technical Field

[0001] The utility model relates to the technical field of fermentation equipment, in particular to a biomass fuel fermentation equipment. Background Art

[0002] Biomass fuel refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.).

[0003] For example, the biomass fuel fermentation equipment with patent number CN220012601U includes a fermentation tank, a feed port, an exhaust port and a sediment outlet mechanism, wherein the feed port is arranged on the fermentation tank, the exhaust port is arranged on the top of the fermentation tank, the sediment outlet mechanism is arranged at the bottom of the fermentation tank, and the sediment outlet mechanism includes a collecting cylinder and a discharge valve, wherein the collecting cylinder is arranged at the bottom of the fermentation tank, and the discharge valve is connected to the bottom of the collecting cylinder. The above document still has deficiencies. When in use, when the biomass fuel in the fermentation tank is fermented by microorganisms to generate combustible gas, the combustible gas enters the gas collection pipe through the exhaust port. Due to the high temperature in the fermentation tank, the combustible gas will contain a lot of water vapor. Therefore, when the combustible gas enters the gas-water separator and passes through the gas-liquid separator, the combustible gas will be discharged into the gas collection pipe through the exhaust port. The separated and dried combustible gas is discharged through the purified gas outlet, and the water produced by the gas-water separator enters the branch pipe at the bottom. The staff opens the control valve on the reflux pipe, and the water produced by the gas-water separator flows back to the fermentation pipe to be re-used for the dilution of the microbial liquid fermentation. However, the feeding port in the above document is set small, and the biomass fuel needs to be crushed and ground in external equipment before it can be added to the fermentation equipment. When there is no external grinding equipment, the biomass fuel cannot be added, making it inconvenient to add the biomass fuel to the fermentation equipment when the fermentation equipment is in use. At the same time, the above document uses a pressure-limiting valve to achieve exhaust inside the fermentation equipment. During the exhaust process, air will enter the fermentation equipment, thereby affecting the fermentation effect of the fermentation equipment. Utility Model Content
