Description

A kind of STAIC high efficiency anaerobic reactor

Technical field

The utility model relates to anaerobic reactor, specifically a kind of STAIC high efficiency anaerobic reactor.

Background technology

The higher anaerobic reactor of anaerobic reaction rate is TAIC anaerobic reactor (noting: TAIC anaerobic reactor is one of utility model people) at present, this reactor is superimposed two UASB reactors and form the up big and down small turriform in square section, its inside holds fermented feed liquid and carries out anaerobic reaction fermentation, inside two UASB stacks is provided with up return line, triphase separator, cloth tube, top is also provided with gas-liquid separator, active cycle pump, compare with IC in this case, TAIC anaerobic reactor has effectively improved the organic loading rate of charging, make it be easy to realize the interior moving circulation of feed liquid, and strengthened the impact resistance of anaerobic reactor.

Yet TAIC anaerobic reactor is in application for many years, and we have found that again new problem occurs: (1) inadaptable feed liquid containing solid suspension object height is carried out the internal recycle starting at initial stage.(2) feed liquid is difficult in container automatically or natural flow moves adjusting.(3) cannot accurately control the starting operation time of anaerobic reactor, cause the starting time longer.(4) the water outlet water level of anaerobic reactor is high, and container internal pressure increases, and requires pond body must increase resistance to compression coefficient, causes anaerobic reactor building cost to increase.

Embodiment

With reference to Fig. 1, the utility model is by automatic Regulation feed tank 1, shield cap 2, automatic traction current circulator 3, feed-pipe 4, up return line 5, cloth system 6, adjustable speed recycle pump 7, lower reaction tank 8, scum pipe 9, lower reaction tank gas-liquid separator 10, upper reaction tank gas-liquid separator 11, upper reaction tank 12, inclined connecting pipe 13, pneumatic tube 14, melt cinder upflow tube 15, return line 16, triphase separator 17 forms.Upper reaction tank 12 is superimposed upon above lower reaction tank 8, triphase separator and inclined connecting pipe are arranged on the top dual-side of lower reaction tank 8, adjustable speed recycle pump 7 is arranged on return line 16, lower reaction tank 8 respectively with up return line 5, lower reaction tank gas-liquid separator 10, return line 16, feed-pipe 4 is connected, automatically regulate 1 of feed tank respectively with automatic traction current circulator 3, feed-pipe 4 is connected, shield cap 2 is arranged on the top of automatic traction current circulator 3, feed-pipe 4 is connected with cloth system 6, scum pipe 9 is tilting in lower reaction tank 8 and upper reaction tank 12, the bottom of row's end slag pipe 9 is inserted in lower reaction tank 8 bottoms, mouth of pipe upper end open is in the outside of upper reaction tank 12, upper reaction gas liquid/gas separator 11 is connected with pneumatic tube 14 with lower reaction gas liquid/gas separator 10, melt cinder upflow tube 15 communicates with upper reaction tank 12.

During the operation of STAIC reactor, feed liquid enters automatic traction current circulator 3 from automatic adjusting feed tank 1 by shield cap 2, be pressed into feed-pipe 4 and form gravitation undershoot, lower reaction tank 8 inside with the compound of active particle by up return line 5, return line 16 is drawn in feed-pipe 4 and fully mixes, by cloth system 6, be evenly distributed in lower reaction tank 8 more afterwards, owing to thering is extremely strong descending surging force, the feed liquid that makes it to enter into lower reaction tank 8 can produce the effect that be uniformly mixed with the feed liquid of lower reaction tank 8, therefore, the feed liquid going up in reaction tank 12 or lower reaction tank 8 is all fully mixed, and start to occur effecting reaction, the biogas of output rises and collects via triphase separator 17, again then enter in up return line 5 with up return line 5 in gas-liquid mixed after form pneumatic up, in up return line 5, outer feed liquid has density difference, so cause the lifting force of a pneumatic rising, can automatically feed liquid be promoted through return line 16, feed-pipe 4, cloth system 6 refluxes in lower reaction tank 8, the biogas that produces by lower reaction tank gas-liquid separator 10, collect and enter into pneumatic tube 14.The feed liquid of tentatively degrading in the interior process of lower reaction tank 8 is in inclined connecting pipe 13 enters into instead with regard to pond 12, further react again degraded, mix natural pond liquid and discharge through melt cinder upflow tube 15, institute's biogas that produces, by upper reaction tank gas-liquid separator 11 collections, enters into pneumatic tube 14.Again because the feed liquid of the automatic traction current circulator 3 in the middle of STAIC inside reactor has descending surging force, there is pneumatic up power with the gas of up return line 5, thereby can impel, feed liquid in lower reaction tank 8 is automatical and efficient, high-speed circulating, starting and the working time of STAIC reactor have greatly been shortened, thereby reach, improve organic degradation speed, improve factor of created gase.
