Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Further understand and understanding for making constitutional features of the present utility model and the effect reached had, cooperate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
Referring to Fig. 1, a kind of pair of internal circulating anaerobic granule sludge biochemical reactor, comprise tower body 100, bottom in the tower body 100 is provided with water distributor 200, waste water enters in the tower body 100 by water distributor 200, mixes with granule sludge, and begins to occur biochemical reaction, organism (CODcr) is degraded, and produces simultaneously biogas.Because the water distribution angle of water distributor 200 can make water distribution energy performance maximum efficiency for tilting.
The top of water distributor 200 is provided with one-level sludge gas collecting device 310, one-level sludge gas collecting device 310 is turbination, and the part of tightening up of obconic top is provided with outlet, the one-level sludge gas collecting device 310 of this spline structure can be with open the tighten up part of collecting top of most biogas from the turbination bottom, and be provided with effuser 410 in the exit, upper end of one-level sludge gas collecting device 310, the entrance of effuser 410 is connected to the upper end outlet of one-level sludge gas collecting device 310, outlet connects outside the tower body 100, can be transferred out tower body 100 outsides by effuser 410 by one-level sludge gas collecting device 310 collected biogas like this.
Be provided with pulser 411 in the ingress of effuser 410, the biogas of collecting by one-level sludge gas collecting device 310 concentrates on 411 1 points of pulser, carry waste water secretly and produced strong temporary impact effect, the purpose of pulse is to make the interior gas of inner loop pipeline suddenly big or suddenly small, the theoretic continuous operation of internal recycle is become the intermittent operation that existing continuous operation has again large flow, to promote the generation of whole system internal recycle.The above-mentioned effect that one-level sludge gas collecting device 310 and pulser 411 produces has also promoted the interior space of itself and tower body to produce the convection current than hard intensity, waste water and granule sludge are mixed more fully, strengthened again organic mass transfer effect, improve the processing power of reactor, and then promoted again the generation of biogas.In convection process, the cone inclined-plane of one-level sludge gas collecting device 310 outside surfaces has also promoted the generation of granule sludge to a certain extent simultaneously.
Also be connected with secondary sludge gas collecting device 320 outside the ingress of effuser 410, some is not passed through collected by secondary sludge gas collecting device 320 by one-level sludge gas collecting device 310 collected biogas, pulser 411 places that also are transported to effuser 410 converge.
Also comprise the second circulating line 420 in the tower body 100, the entrance of the second circulating line 420 is communicated with in the water of tower body 100 inner bottom parts, outlet is communicated with outside the tower body 100, the middle part of the second circulating line 420 is provided with gas-liquid separator 421, the effect of the second circulating line 420 is that carrying waste water secretly when biogas in the process of the second circulating line 420 interior risings rises, after arriving tower body 100 tops, biogas is discharged tower body 100, and waste water drops to reactor bottom, produce surging force, promote the mixing of granule sludge and waste water, final purpose is to promote organic contact the in granule sludge and the waste water, thereby the raising water treatment effect, internal recycle also can play diluting effect to other index of water quality simultaneously.A key point in this process is exactly the gas-liquid separator 421 of the middle part setting of the second circulating line 420, and other products all can cause a large amount of granule sludges to enter the internal recycle pipeline upcast by the second circulating line 420 at present, make this line clogging.But the gas-liquid separator 421 that arranges at the middle part of the second circulating line 420 has solved this problem.Gas-liquid separator 421 it can allow biogas enter smoothly the internal recycle pipeline upcast, also allow simultaneously granule sludge within it section rely on the gravity separation that descends, thereby avoided the obstruction of upcast.Internal recycle increase in pipeline end structure is also very exquisite simultaneously, can not allow in theory any one granule sludge enter the inner loop pipeline system, has avoided line clogging, and current other products can not head it off.The ingress of the second circulating line 420 is provided with granule sludge internal recycle device 422, the effect of granule sludge internal recycle device 422 is to promote the granule sludge of tower body inside to carry out the top and the bottom circulation, guarantee that granule sludge can both touch the organism of higher concentration, thereby avoid the granule sludge in the epicoele 110 to be in for a long time the granule sludge change that causes under the low load condition.
Secondary sludge gas collecting device 320 is arranged at the middle part in the tower body 100, will be divided into epicoele 110 and cavity of resorption 120 in the tower body 100, and is provided with the gap between secondary sludge gas collecting device 320 and tower body 100 inwalls.Simultaneously also be provided with three grades of sludge gas collecting devices 330 at the top of tower body 100.Waste water has entered epicoele 120 by the gap between secondary sludge gas collecting device 320 and tower body 100 inwalls after processing in cavity of resorption, carry out precision processing, produce simultaneously a small amount of biogas, collected by three grades of sludge gas collecting devices 320, do not enter the inner loop pipeline system, directly discharge reactor.
The utility model mixes waste water and granule sludge so that produced convection current than hard intensity in the tower body more fully, has strengthened again organic mass transfer effect, improves the processing power of reactor, and then has promoted again the generation of biogas.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and the specification sheets is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in the claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
