Embodiment
A kind of self-mixing anaerobic reactor is made up of reactor base plate 1, reactor shell 2, reactor end socket 3, charging house steward 5, escape pipe 14, shore pipe 15.Reactor shell 2 is the vertical type cylinder tubular construction, and its lower end is provided with reactor base plate 1, and the upper end is provided with reactor end socket 3, and reactor end socket 3 tops connect escape pipe 14; Reactor shell 2 bottoms are respectively equipped with charging house steward 5 and shore pipe 15.
Charging house steward 5 opening parts connect several chargings and are in charge of 16, and it is uniform above reactor base plate 1 that 16 exit end is in charge of in charging, and it is dismountable flange arrangement that 16 feed end is in charge of in charging.Charging house steward 5 is arranged on outside the reactor, as cleaning easily takes place to stop up; Charging is in charge of 16 and is told by charging house steward 5 openings, as stops up, and flange can be taken apart, separately cleaning.
Charging is in charge of 16 terminal belows cone-shaped cloth device 4 is set, and cone-shaped cloth device 4 is conical, and its material is carbon steel or stainless steel.The vertex of a cone is in charge of 16 center in charging, and when charging was in charge of feed liquid in 16 and is flowed through cone-shaped cloth device 4 downwards, the flow direction changed, and is tilted to current downflow along cone-shaped cloth device 4 trochoidal surfaces, and is diffused as a circular cloth pool.
Reactor shell 2 inside are provided with pod 7, sealing gland 8, following pod 6 from top to bottom successively.It is conical that last pod 7 is, and the vertex of a cone upwards; It is conical that following pod 6 is, and the vertex of a cone is downward.
Reactor shell 2 inner and upper are provided with overflow weir 9, overflow weir 9 surrounds annular groove with reactor shell 2, overflow weir 9 bottoms are connected with downtake 10, downtake 10 lower ends are provided with liquid packing 11, connect discharge nozzle 12 on the liquid packing 11, discharge nozzle 12 discharge ends stretch out reactor shell 2 and opening is provided with down; Liquid packing 11 tops connect equilibration tube 13, and equilibration tube 13 ends stretch out reactor end socket 3 and bending down.
Reactor is vertical, cylindrical, adopts the weldering of carbon steel or stainless steel coiled sheet to form.Reactor base plate 1, cone-shaped cloth device 4, sealing gland 8 and liquid packing 11 adopt carbon steel or stainless steel plate to make.Reactor shell 2, down pod 6, go up pod 7 and overflow weir 9 adopts carbon steels or the weldering of stainless steel coiled sheet to form.Reactor end socket 3 adopts carbon steel or stainless steel plate weldering system, and is certain circular arc arch.
Charging house steward 5, downtake 10, discharge nozzle 12, equilibration tube 13, escape pipe 14, shore pipe 15, charging are in charge of 16 and are all adopted carbon steel or stainless steel tube to make, and concrete size can be set, adjust according to operating mode.
Concrete working process is as follows:
Material (cow dung, pig manure etc.) enters each charging respectively by charging house steward 5 and is in charge of 16, when charging is in charge of feed liquid in 16 and is flowed through cone-shaped cloth device 4 downwards, the flow direction changes, be tilted to current downflow along cone-shaped cloth device 4 trochoidal surfaces, and be diffused as a circular cloth pool, and with after prepositioned active sludge in the anaerobic reactor contacts in the usual way anaerobically fermenting produce biological flue gas, natural pond liquid and natural pond slag.
Pod 6 upwards flowed with reactor shell 2 formed annular regions under the biological flue gas that material and fermentation produce passed through, and through the baffling effect of sealing gland 8, material and biological flue gas make progress mobile by the centre of last pod 7; Active sludge and solid particulate with settling property then flow downward with reactor shell 2 formed annular regions along last pod 7, through the baffling effect of sealing gland 8, active sludge and solid particulate with settling property then flow to reactor bottom in the centre of pod 6 down in the edge.Circulate so continuously, feed liquid in the reactor is played from the blended effect.
Biological flue gas separates the back and discharges reactor by biological flue gas escape pipe 14 with feed liquid; When the feed liquid liquid level behind anaerobically fermenting surpasses the upper end of overflow weir 9, feed liquid just overflow enters overflow weir 9, enter liquid packing 11 by downtake 10 then, when the feed liquid liquid level in the liquid packing surpassed discharge nozzle 11 tops, material was that overflow enters discharge nozzle 11 and outflow reactor; The biological flue gas that produces is extracted out because syphonic effect will ferment when preventing that feed liquid from flowing out liquid packing 11, so equilibration tube 13 and external world's communication are set on liquid packing 11 tops.
The sediment, mud etc. that are deposited in anaerobic reactor bottom are regularly discharged by shore pipe 15.
