NOVELTY - Fabric energy-saving high concentration anaerobic fermentor comprises a vertical barrel anaerobic fermentor main body (1) provided with an inner fabric nozzle (2) in its upper part, a reflow pump and return pipeline to analyze bottom flow space of slurry so that the three-way solid-liquid blender (3) conveys the slurry to fabric nozzle. The solid material is conveyed to preheater (5) and connecting tube (4) through screw extruder or piston. The return pipeline is installed with the three-way solid-liquid blender, and after refluxing the biogas slurry is mixed and delivered to the cloth nozzle.    USE - Used as fabric energy-saving high concentration anaerobic fermentor.    ADVANTAGE - The fermentor is suitable for gas biological engineering research field and prepares high efficiency energy-saving product.    DETAILED DESCRIPTION - Fabric energy-saving high concentration anaerobic fermentor comprises a vertical barrel anaerobic fermentor main body (1) provided with an inner fabric nozzle (2) in its upper part, a reflow pump and return pipeline to analyze bottom flow space of slurry so that the three-way solid-liquid blender (3) conveys the slurry to fabric nozzle. The solid material is conveyed to preheater (5) and connecting tube (4) through screw extruder or piston. The return pipeline is installed with the three-way solid-liquid blender, and after refluxing the biogas slurry is mixed and delivered to the cloth nozzle. The fermentor body upper layer is set with multiple levels or single-level heaters. In the lower part of heater, production intercepted high solution suspension is passed into anaerobic dry fermentation bed to precipitate and enters into biogas slurry trapezoidal tapered hopper and sleeve umbrella-shaped cone. The production catheter provided on top part of umbrella-shaped cone, which is connected with valve and slurry pump. The slurry pump is connected with solid-liquid separator squeeze pump. The solid-liquid separator squeeze pump is connected with spiral solid-liquid separating machine.
