Description
Technical field
The utility model relates to a kind of equipment for organic waste water anaerobic treatment, particularly a kind of IC anaerobic reactor.
Background technology
IC(Internal Circulation) anaerobic reactor, claims again internal-circulation anaerobic reactor, is a kind of efficient anaerobic reactor.It comprises a tank body, and tank body shell is the cylindrical of straight tube, is divided into reaction chamber and lower reaction chamber in tank body shell.One gas-liquid separator is arranged at the outer top of upper reaction chamber, and upper reaction chamber inside is provided with triphase separator, gas collector and riser tube.One water distributor is arranged at lower reaction chamber bottom.In tank body, also have a return line through the upper and lower reaction chamber of IC anaerobic reactor, return line upper end is connected with gas-liquid separator, and lower end is connected with water distributor.The water inlet pipe of tank body peripheral hardware enters the water distributor of lower reaction chamber bottom, and the organic waste water that enters reactor from water distributor mixes mutually with mud and produces biogas.Biogas rise and collected by gas collector, then enter riser tube and gas-liquid separator.When biogas rises along riser tube, fermented liquid can be promoted to gas-liquid separator simultaneously.Enter the fermented liquid of gas-liquid separator, under the effect of gravity, by return line, again turn back to lower reaction chamber from top to bottom, form internal recycle.Internal recycle can increase the hydraulic load of reaction chamber under IC anaerobic reactor, can improve the rate of mass transfer between organism and mud, makes IC anaerobic reactor have higher volumetric loading.
But, current all IC anaerobic reactors, its shell is all the cylindrical of straight tube, the diameter of upper and lower reaction chamber equates, like this make gas collector, triphase separator, time, consumptive material is large especially, and is difficult to guarantee the quality of site operation.
Traditional IC anaerobic reactor, the volume of upper reaction chamber accounts for the more than 1/3 of whole IC anaerobic reactor volume conventionally, and so large volume does not but have too large effect to digestion of organic matter, thereby has reduced the processing efficiency of IC anaerobic reactor integral body.
In addition, traditional IC anaerobic reactor, its volumetric loading is subject to elbow in the reactor upflow velocity of intaking, and can not make well processing efficiency improve.And, water inlet pipe outside outer casing bottom is passed into after enclosure, the water distributor connecting is at most also whirlwind-type water distributor, this traditional whirlwind-type water distributor comprises water distribution umbrella taper, that tip makes progress and is positioned at many water distribution branch pipes within water distribution umbrella, water distribution branch pipe end is provided with nozzle, and head end is communicated with water inlet pipe by the divider being located at outside reactor; Each nozzle is positioned at same water outlet circumference, and this water outlet circumference is vertical with water distribution umbrella axis, and each nozzle is pasting water distribution umbrella inwall, and water outlet circumference is pasting water distribution umbrella inwall.Yet, divider is arranged on reactor outside, for the nozzle of realizing on water outlet circumference uniform, it is different that water distribution branch pipe moves towards, accessory disunity, installation requirement is high, and quantities is large, and do not have fully the liquid refluxing in return line to be fully utilized, water inlet does not reach integrated completely yet with internal recycle.
Utility model content
The technical problems to be solved in the utility model is: a kind of reducing IC anaerobic reactor is provided, it can simplify traditional triphase separator of isometrical IC anaerobic reactor and the making processes of gas collector, and save and make material, can also improve the volumetric loading of IC reactor simultaneously, increase processing power.
The solution that the utility model solves its technical problem is:
Reducing IC anaerobic reactor, comprises tank body, and the shell from top to down of tank body comprises epimere, stage casing and hypomere three parts, and upper intersegmental part has gas-liquid separator and upper reaction chamber, and upper reaction chamber inside has again triphase separator and gas collector; Lower intersegmental part is lower reaction chamber, and there is water distributor its inside; Described epimere and hypomere are cylindrical, the top and bottom in stage casing respectively with being connected with the top of hypomere bottom of epimere, and the diameter in stage casing narrows from bottom to up gradually, makes the diameter of reaction chamber be less than the diameter of lower reaction chamber.
As the further improvement of technique scheme, the connecting portion of described stage casing and hypomere and/or stage casing with the connecting portion of hypomere for to be directly connected.
As the further improvement of technique scheme, the connecting portion of the connecting portion of described stage casing and hypomere and/or stage casing and hypomere is round-corner transition.
As the further improvement of technique scheme, described stage casing integral body is round table-like.
As the further improvement of technique scheme, upper reaction chamber diameter is lower reaction chamber 1/2nd or less.
In a word, roughly thinking of the present utility model is: by changing the method in upper reaction chamber footpath, dwindle diameter and the volume of reaction chamber, make the shell of IC anaerobic reactor from top to bottom, be divided into upper, middle and lower segment.Upper intersegmental part is installed gas collector, triphase separator, riser tube, and gas-liquid separator is also included; Lower intersegmental part is installed whirlwind-type water distributor; Return line runs through upper and lower two reaction chambers of reactor.Upper reaction chamber diameter is less than lower reaction chamber, and stage casing is as transition section.
The beneficial effects of the utility model are: the utility model has changed the structure of traditional isometrical IC anaerobic reactor, but adopt lower large little variable diameter design, dwindled the diameter of upper reaction chamber, this on normal internal recycle without any impact, but gas collector, triphase separator, these devices of gas-liquid separator of but making to form internal circulation apparatus are made and are become more simple, and saved making material.Even if but become large the holding back of mud that be unfavorable for because the diameter of upper reaction chamber diminishes, can make the hydraulic load upflow velocity that increases upper reaction chamber, therefore what unique, need consideration is, the upflow velocity of reactor water inlet can not be too large, therefore the utility model is more suitable for the organic waste water for the treatment of high density (CODcr is up to tens thousand of mg/litre), and this has overcome the weak point that conventional IC anaerobic reactor is difficult to process high-concentration waste water exactly.The utility model is simple, and volumetric loading is high, is applicable to high concentrated organic wastewater to carry out anaerobic treatment.
