Description

Technical Field

[0001] The utility model relates to the technical field of biogas fermentation, in particular to a hydrolysis enhanced anaerobic device. Background Art

[0002] Anaerobic hydrolysis and acidification is a treatment process for raw materials during biogas fermentation. During anaerobic fermentation, the raw materials will go through the following four stages: hydrolysis stage, acidification stage, acetic acid production stage, and methanogenesis stage. During hydrolysis and acidification, the high molecular or cyclic organic matter in the wastewater is broken or opened under the action of extracellular enzymes, and converted into small molecular organic matter that can pass through the cell membrane and be transferred into the cell. In the acidification stage, the small molecular organic matter that enters the cell is further converted into simpler compounds (organic acids, alcohols, lactic acid, etc.) and secreted outside the cell, thereby facilitating the reaction.

[0003] Most of the existing hydrolysis devices are hydrolysis acidification tanks. When in use, the raw materials are injected into the tank body and hydrolyzed. The hydrolysis acidification tank is equipped with a stirring device to stir the raw materials in the tank so that the hydrolyzing microorganisms and the raw materials can fully contact and react. However, the stirring device can only stir the surroundings of the tank body. Some solids and mud with larger gravity will settle at the bottom of the tank, resulting in insufficient hydrolysis. Utility Model Content

[0004] In view of the above situation, in order to make up for the deficiencies of the prior art, the purpose of the utility model is to provide a hydrolysis enhanced anaerobic device, which effectively solves the problem that materials in the existing hydrolysis tank are easy to sink to the bottom.

[0005] The technical solution is that the utility model includes a tank body with upper and lower axial directions, a rotating tube with upper and lower axial directions and capable of rotation is arranged in the tank body, a plurality of ventilation holes evenly distributed along its circumferential direction are opened on the lower side of the rotating tube, an aeration cylinder with an opening facing inward is arranged in the ventilation hole, a plurality of aeration holes are opened on the upper end of the aeration cylinder, a plurality of stirring blades are arranged on the rotating tube, an air supply pipe inserted into the rotating tube is arranged on the upper end of the tank body, and the air supply pipe is coaxially rotatably connected with the rotating tube.

[0006] Compared with the prior art, the utility model has the following beneficial effects: the raw materials in the feed pool can be hydrolyzed and acidified, so that the small molecular organic matter entering the cells is further converted into simpler compounds (organic acids, alcohols, lactic acid, etc.) and secreted outside the cells, thereby enhancing the effect of anaerobic fermentation; at the same time, the raw materials in the tank body can be stirred and aerated to mix the raw materials evenly, thereby preventing solid matter such as mud in the raw materials from settling to the bottom of the tank body and causing insufficient hydrolysis.
