Interior organic matter fermentation completely after, it is necessary to discharge fermentation residue, and when adding new material and being fermented, stirring pump can be opened
51, High-Pressure Water enters anaerobic cavity by bottom, and the mixed liquor in anaerobic cavity 12 can be sufficiently stirred by it, then extracts obstruction pipe out
57, mixed liquor enters aerobic cavity 11 under gas pressure, more abundant due to stirring, and most of fermentation residue enters aerobic with current
In chamber 11, obstruction pipe 57 is plugged, return valve 55 is opened and air bleeding valve 42, biogas is discharged by blast pipe 41, while in aerobic cavity 11
Mixed liquor it is synchronous entered by the first return duct 54 in anaerobic cavity 12, and fermentation residue is then left on screen pack 53, when biogas is complete
After the completion of portion is collected, the liquid in aerobic cavity 11 is all back in anaerobic cavity 12, and fermentation residue is then left in filter frame 52,
Filter frame 52 can be taken out by backflash 21 and pour out fermentation residue, filter frame 52 can be reapposed in backflash 21.In order to
It is easy to flow back, there is certain gap, and screen pack 53 is fixed on filtering between the lower end of filter frame 52 and the bottom of backflash 21
On the inwall of frame 52 so that filter frame 52 can give screen pack 53 with support force, so as to extend the service life of screen pack 53.
During specific setting, dividing plate 2 is generally cement structures, and the lower surface of the present embodiment dividing plate 2 sets spherical structure, upper surface
It is arranged to horizontal structure so that dividing plate 2 has larger thickness close to its outer rim, and backflash 21 is then set close to the outer rim of dividing plate 2
Put, and in order to avoid the excrement of supplement charging blocks screen pack 53 into backflash 21, it can be set and covered with backflow by backflash
21 cappings, backflow lid is opened when deslagging.It should be noted that backflash 21 can be arranged as required to it is multiple, it is multiple
Backflash 21 can be uniformly arranged along dividing plate 2 is circumferential, and filter frame 52, screen pack 53, the first return duct 54 and return valve 55 are then one by one
It is correspondingly arranged multiple.
In order to ensure the acquisition time of biogas, the bottom of the present embodiment dividing plate 2 is provided with baroceptor, works as baroceptor
When the air pressure of detection reaches setting value, the collection that air bleeding valve 42 carries out biogas can be opened, it can be avoided because of air pressure in anaerobic cavity 12
It is excessive and produce dangerous.
