Embodiment Construction

[0010] See attached figure 1 , 2 , 3, 4, a kind of energy-saving high-concentration anaerobic fermenter with upper cloth disclosed by the present invention is characterized in that: a cloth nozzle 2 is erected on the upper part of the vertical bucket type anaerobic fermenter body 1, and a reflux pump 7 and The reflux pipe 6 draws out the biogas slurry from the eluate flow space 14 at the bottom of the fermenter body 1, so that it is transported to the distribution nozzle 2 through the solid-liquid mixing tee 3, and the solid material is communicated with a screw extruder or a plunger pump. The pre-heater 5 and the communication pipe 4 are mixed with the return biogas slurry by the solid-liquid mixing tee 3 installed on the return pipe 6, and then sent to the cloth nozzle 2 to complete the upper cloth, and the middle and upper layers of the fermenter body 1. One-stage or single-stage heater 11, under the heater 11, a trapezoidal cone bucket 12 and a jacket umbrella-shaped con...

Abstract

The invention discloses a top-distribution energy-saving high-concentration anaerobic fermentor and belongs to the technical field of biogas engineering practice. The top-distribution energy-saving high-concentration anaerobic fermentor is characterized in that top distribution is completed through the steps of mixing solid materials with a reflux biogas slurry via a solid-liquid mixing three-way joint mounted on a reflux pipeline by use of a solid material preheater communicated with a screw extruder or a plunger pump, and a communicating pipe, and then conveying the mixture to a rotating distribution nozzle, besides, a trapezoidal conical funnel for gathering and intercepting high-concentration materials and separating out the biogas slurry is arranged under the heater and inserted into an umbrella-shaped cone to gather the materials to ensure ordered discharge without disordered layer thickness in ordered fermentation, and the biogas slurry with the heat value is recycled by use of biogas slurry reflux and direct solid-liquid separation, and consequently, high-efficiency energy saving is realized. The top-distribution energy-saving high-concentration anaerobic fermentor is innovative and practical in that a top-distribution vertical-barrel type anaerobic fermentor is fabricated into a high-efficiency energy-saving product in the field of biogas engineering research.

Description

technical field [0001] The invention discloses an upper cloth energy-saving high-concentration anaerobic fermenter, which belongs to the practical technical field of biogas engineering. Background technique [0002] Bottom feed and top discharge vertical barrel anaerobic fermenter, relying on the buoyancy of water ( F=G-F ) effect, the middle and upper layers of the barrel form a high-concentration anaerobic fermentation with a solid content of about 30%, and the vertical barrel anaerobic fermenter with upper feeding and lower unloading relies on the buoyancy of water to form anaerobic fermentation in the middle and upper layers The most important is the high-concentration material suspension layer, which is thickened and extended from the top to the next step to the bottom unloading, and the space occupied by the high-concentration anaerobic fermentation layer of the two is 60% of the height of the material capacity of the barrel. The above shows that the fermentation form...
