Description

The IC anaerobic reactor

Technical field

The utility model relates to the physics sewage disposal device, particularly has the anaerobic reactor of solid, liquid, gas three phase separation function.

Background technology

The IC reactor is the IC anaerobic reactor, is a kind of multistage efficiently inner circulation reactor, be the 5th generation anaerobic reactor typical case representative, in 1986 by the invention of Dutch Paques B. V..Nineteen ninety-five, the Parker enters China, precedingly is provided with company in Shanghai, is responsible for promoting the use of its IC reactor specially.

The IC reactor is compared with third generation anaerobic reactor UASB, and it has volumetric loading height (can reach 12-50kgCOD/m3d), and capacity of resisting impact load is strong, the high advantage of removal efficient.Extremely abstruse because of this reactor design structure, cultivate extremely complexity of granule sludge technical requirements, only there is Very few companies that successful case is arranged both at home and abroad.Existing IC reactor (as, ZL200620084006.2) remain shortcoming unreasonable in structure design, that the three phase separation effect is relatively poor.

The utility model content

The purpose of this utility model provides a kind of reasonable in design, effective, the costly IC anaerobic reactor of biogas utilization of three phase separation.

This novel purpose is achieved in that a kind of I C anaerobic reactor, comprise vertical tank body, be arranged on gas-liquid separator, upcast and the downtake of tank body top, different heights position, vertical tank intracoelomic cavity top is provided with two triphase separators: by be obliquely installed, following reflector tapered, its upper opening constitutes with the last reflector parallel, tapered with following reflector.

Above-mentioned vertical tank body internal frame is provided with prismatic triangle sealing gland beam; Triphase separator is installed on the prismatic triangle sealing gland beam.

Above-mentioned vertical tank intracoelomic cavity top is provided with triangle and collects tank.

Compared with prior art, this novel beneficial effect is:

1, volumetric loading height:

Sludge concentration height in the IC reactor, microbial biomass is big, has internal recycle, and mass transfer effect is good, and the water inlet organic loading can surpass more than 3 times of common anaerobic reactor.Therefore, when handling same waste water, its volume only needs 1/3rd of traditional anaerobic reactor (as: UASB).

2, anti-portative power is strong:

Common anaerobic reactor as: ABR, the highest water inlet of UASB COD load can not be higher than the highest water inlet of 8000-10000. IC reactor COD then can be up to tens thousand of, even hundreds thousand of.

3, working cost is low:

The backflow of common anaerobic reactor realizes by external pressurized, and the IC reactor is realized the mixed solution internal recycle with the biogas that self produces as the power that promotes, and needn't establish the pump pump circulation, has saved power consumption, has reduced working cost.

4, COD clearance height:

For the waste water that reaches IC reactor water inlet condition, its COD clearance can be up to more than 80%.Utilize the classification anaerobic treatment, can compensate the high disadvantageous effect that produces of Ks in the anaerobic process.

5, start-up period is short: sludge activity height in the IC reactor, biological propagation is fast, provides favourable condition for reactor starts fast.The IC reactor start-up cycle is generally 1～3 month, and common UASB start-up period reaches 4～6 months.

6, biogas utilization is worth high: the biogas purity height that reactor produces, and CH4 is 70%～80%, and CO2 is 20%～30%, and other organism is 1%～5%, can be used as fuel and is used.

Embodiment

Fig. 1 illustrates, this is novel to comprise vertical tank body 1, be arranged on the gas-liquid separator of tank body top, upcast and downtake, different heights position, vertical tank body 1 inner chamber top is provided with two triphase separators 3: by be obliquely installed, following reflector 3a tapered, its upper opening constitutes (referring to Fig. 2, Fig. 4, Fig. 5) with the last reflector parallel, tapered with last reflector 3b.The waste water import is arranged at vertical tank body 1 bottom.Be provided with internal circulation system in the tank body, gas-liquid separator is positioned at the tank body top, and gas-liquid separator is connected by the cyclone water distributor of return line with the tank body lower end, also is connected (not shown) with downtake with a jar intravital triphase separator by upcast.Vertical tank body 1 internal frame is provided with prismatic triangle sealing gland beam 2; Triphase separator 3 is installed on the prismatic triangle sealing gland beam, also we can say, promptly reflector is directly installed on the prismatic triangle sealing gland beam under the triphase separator warp.Rhombus sealing gland beam mainly plays guide functions, to help mass transfer process.Top of chamber is provided with triangle and collects tank 4 in the vertical tank body 1, among Fig. 3, concave notches 4a is arranged on the tank 4, and overflow water flows out through overflow weir.

IC reactor profile is vertical tank body, highly from 16 meters to 28 meters, and, diameter is from 1.5 meters to 15 meters.The waste water of need handling uses efficiently that water distribution system pumps into reactor by reactor bottom, mixes with anaerobic grain sludge in the reactor.At reactor lower part is main treatment zone, and most organic matter is converted into methane and carbonic acid gas.These mixed gass (perhaps being called biogas) are collected by the triphase separator of bottom." gas is carried " that produces drives current and enters the gas-liquid separator of reactor head by upcast.Biogas overflows reactor from this separator, current are got back to the bottom of reactor through downtake.Based on this principle: reactor is named as inner circulation reactor.In the precision processing district on top, waste water is further processed.Biogas spins off in the liquid phase in precision processing stage, is then collected by the triphase separator on top, and treated water is discharged from reactor head.

The engineering experience that the applicant handles according to industrial sewage for many years and to the research experience of anaerobic reactor, the improvement of having done aspects such as eddy flow water distribution, multi-phase gas-liquid separation on Parker I C reactor basis is perfect, this novel I C anaerobic reactor is tried out in the sewage disposal of industries such as beer, papermaking, chemical pharmaceutical, and the COD clearance is up to 80%.No matter this is novel is that operating performance or equipment price are compared with Paques B. V., and greater advantage is all arranged, and (IC of Paques B. V. reactor cost is 10,000/m ³, and the cost of my IC of company reactor only be equivalent to the Parker half).
