Abstract

An anaerobic reactor belongs to wastewater treatment technology field. The reactor is mainly made up with a tank that includes a biogas pipe, a blow-down pipe, an anti-explosive port, a feed pipe, a feed distributor, a central pipe, a three-phase separator and a feed outlet. The anti-explosive port is arranged the top of outside tank, the blow-down pipe is extended outward on the bottom of the tank. A middle container and an inner container is arranged in the tank from outside to inner, the bottom of the middle container is fixed on the bottom of tank by a stent and the bottom of inner container is connected with the bottom of tank to fix. The top of the middle container and the inner container connects with each other and space exists between the top of containers and tank. The feed inlet is connected with the inner container by the feed distributor, the central pipe is fixed in the middle of the tank and is linked with the feed distributor, the blow-down pipe, the feed distributor and feed pipe respectively, the feed outlet is arranged on the lower part of the central pipe. The utility model can remove COD in wastewater at high percent and does not need external power, recycling operation, low-cost, steady performance, easy to operate and safe.

Description

A kind of anaerobic reactor

(1) technical field

The utility model belongs to technical field of waste water processing, particularly a kind of anaerobism reflecting device.

(2) background technology

Anaerobic reactor is the necessaries of anaerobism sewage disposal, and anaerobic reactor commonly used at present is a contact anaerobism reflecting device.The contact anaerobic reactor has stronger adaptability to potato alcohol, but shortcoming is: 1, additional power need be set promote circulation, equipment energy consumption is big, running cost is high; 2, the charging cross section is big, and pulse power is little; 3, because of reasons in structure, the suspended matter that dynamically ferments is difficult for precipitation, water outlet suspended matter concentration height, and the COD clearance in the waste water is low.

(3) summary of the invention

The utility model is at the deficiencies in the prior art, provides that a kind of charging cross section is little, pulse power big, high and do not need to be provided with additional power, internal-circulation type anaerobic reactor that circular flow is good to the COD clearance in the waste water.

The utility model is achieved through the following technical measures.

This reactor mainly is made up of tank body, tank body includes the biogas pipe, blow-off pipe, venting, feed-pipe, feed distributor, pipe core, triphase separator, discharge nozzle, wherein, venting is arranged on the upper end of tank body outside, blow-off pipe is drawn outside jar by tank base, it is characterized in that, courage and inner bag during ecto-entad is provided with in tank body, middle courage bottom is fixed by support and tank base, the lower end and the tank base of inner bag are connected and fixed, in courage communicate with the upper end of inner bag and and the tank body inner top between leave the space, a jar intravital feed-pipe is communicated with inner bag by feed distributor, the top that triphase separator is arranged on outside the middle courage is communicated with discharge nozzle.

In the middle of described pipe core was arranged in the tank body, its bottom was connected with tank base, and the bottom is communicated with blowdown divider and blow-off pipe respectively, the middle part is communicated with feed distributor and feed-pipe, the bottom is provided with discharge port, and open top is connected with the tank body top by bracing frame.

Middle courage bottom has through hole.

The utility model forms internal recycle by inner bag and middle courage are set with feed-pipe, feed distributor, pipe core, triphase separator and discharge nozzle, makes that reactor does not need the recycle system is set in addition, has saved working cost, and running cost reduces greatly; Integral reactor distribution cross section increases from inside to outside gradually, and flow velocity reduces gradually, helps the precipitation of suspended substance, has guaranteed microbial strains quantity and growth conditions, has improved the clearance of COD; Inner bag contains sectional area, and to account for the ratio of reactor total sectional area less, and the water inlet cross section is little, and pulse power is big, and dynamically water distribution is even, and microorganism and organism contact area are big, the waste water treatment efficiency height.Principle of work is as follows: waste water is pumped into feed-pipe, enter inner bag by feed distributor, when the inner bag feed liquid is full, just overflow in the middle courage, enter between middle courage and the cylindrical shell by middle courage bottom, through triphase separator suspended substance is separated the postprecipitation awl end again, gas delivery is to the tank top, and the water after the processing enters discharge nozzle, connect discharge port by pipe core, finished the internal recycle operation.Use the utlity model has that the charging cross section is little, pulse power is big, high and do not need to be provided with additional power to the COD clearance in the waste water, working cost is low, stable performance, advantage such as easy to operate, safe.

Accompanying drawing is the utility model structural representation.

Wherein, 1, cone, 2, cylindrical shell, 3, feed-pipe, 4, feed distributor, 5, middle courage, 6, inner bag, 7, pipe core, 8, the biogas pipe, 9, triphase separator, 10, discharge nozzle, 11, end socket, 12, blowdown divider, 13, venting, 14, blow-off pipe, 15, collection chamber, 16, discharge port.

(5) embodiment

Embodiment: as shown in drawings, the potato alcohol production line of 20,000 tons of throughput, two 5000 cubic metres of volumetrical internal-circulation anaerobic reactors have been adopted, the cylindrical shell 2 of reactor is welded as a whole with cone 1 and end socket 11, constituted a tank body, feed-pipe 3 enters in the tank body and is connected with feed distributor 4, in courage 5 and inner bag 6 be provided with from outside to inside, inner bag 6 and middle courage 5 tops communicate, and and the tank body inner top between leave the space, form collection chamber 15, triphase separator 9 is installed in the top between cylindrical shell 2 and the middle courage 5, is communicated with discharge nozzle 10, and discharge nozzle 10 connects pipe core 7, the bottom of pipe core 7 is connected with tank base, the bottom is communicated with blowdown divider 12 and blow-off pipe 14 respectively, and the middle part is communicated with feed distributor 4 and feed-pipe 3, and the bottom is provided with discharge port 16, open top is connected with the tank body top by bracing frame; Biogas pipe 8 connects a jar intravital top collection chamber 15, at the outside end socket of tank body top venting 13 is set; The blow-off pipe 14 that is arranged on pot bottom is connected with blowdown divider 12.The waste water that with COD is 55000mg/l is squeezed into the bottom that jar intravital feed distributor 4 enters inner bag 6 by feed-pipe 3, waste water is courage 5 from the top of inner bag 6 enters, arrive the triphase separator 9 of cylindrical shell 2 internal upper parts by the through hole of middle courage bottom, enter discharge nozzle 10, discharge from discharge port 16 by pipe core 7, the liquid COD that discharges is 5000mg/l, clearance is 91%, improve 12% than contact anaerobic reactor with scale, saved be equipped with the 7.5KW motor follow two of environment protecting pumps, economize on electricity 28.8%.
