Abstract
The utility model discloses an air-lift type internal circulation biological reactor of honeycomb carrier immobilized cells. The reactor is inside provided with one or a plurality of inner tubes which are filled with honeycomb carriers which contain immobilized cells, the honeycomb carriers are biological catalyst which carries cells and can play the role of a static mixer, and hence, reaction efficiency can be enhanced. Compared with the existing fluidized bed biological reactor, the reaction efficiency of the utility model can be enhanced by 20 percent to 30 percent, and the resistance force is only 15 percent to 25 percent of the resistance force of a packed bed type biological reactor. The utility model is a biological reactor which has extensive application foreground and can be especially used for the biochemical treatment of waste water.
Description
The utility model belongs to microbial immobilized technical field, relates to a kind of immobilized cell bioreactor, relates in particular to a kind of bio-reactor with air lift type internal recycle.
Microbial immobilized technology is an emerging technology in the bioengineering field, has been widely used in fields such as pharmacy, chemical industry, food and environmental protection at present.Rise the eighties, and this technology begins to be applied to the processing of trade effluent.Bio-reactor is one of microbial immobilized core technology, and researching and developing energy-efficient bio-reactor has become a current important topic.
At present, the immobilized cell bioreactor of industrial application mainly contains intermittent type, continuously stirring slot type, filling bed type and fluidized bed type etc.Above-mentioned immobilized cell bioreactor, what have easily makes the immobilized cell fragmentation, and the mass-transfer efficiency that has is not ideal enough, the operational difficulty that has.The fluidized bed type bio-reactor, as document " environmental science ", 1997,18 (1), 26 " the inner loop fluidized bed reactor reactors " reported, operation easier is higher, is difficult for promoting the use of; Other has a kind of air lift type internal circulation biological reactor, though its mass-transfer efficiency is higher than general fluidized bed reactor, and, this reactor because the rising of gas can make small bubbles pool air pocket, causes the reduction of mass-transfer efficiency in operating process.
The purpose of this utility model is to design a kind of air lift type internal circulation biological reactor of honeycomb substrate immobilized cell, with the advantage of comprehensive above-mentioned various reactors, overcomes the defective of its existence.
Design of the present utility model is such: whole reactor is designed to tower shape or cylindric, and portion is provided with one or several interior pipe within it, has loaded the honeycomb substrate that contains immobilized cell in the interior pipe.Be provided with an aerator that has tuyere at reactor bottom, pressurized air can directly enter the interior pipe that contains the immobilized cell honeycomb substrate by aerator.Honeycomb substrate is the biological catalyst that is loaded with cell, can play the effect of static mixer again, therefore can improve reaction efficiency greatly.Compare with existing fluidized bed bio reactor, its reaction efficiency can improve 20%～30%, and resistance only is 15%～25% of a filling bed type.
Below with reference to accompanying drawing the utility model is done detailed explanation.Fig. 1 is the structural representation of described reactor.Fig. 2 is the inner tube structure synoptic diagram that has loaded honeycomb substrate.Fig. 3 is that A-A among Fig. 2 is to synoptic diagram.Fig. 4 is the synoptic diagram of honeycomb substrate.Among the figure:
The 1----housing
Pipe in the 2----
The 3----honeycomb substrate
The 4----venting port
The import of 5----substrate
The 6----support
The 7----aerator
The 8----tuyere
The outlet of 9----product
The 10----clear opening
The 11----space
As seen from the figure, said reactor mainly by housing 1, one or several in pipe 2, honeycomb substrate 3 and aerator 7 constituted.
Said housing 1 is a columniform tower body;
Pipe 2 is the circle straight tube in said, and its diameter is 60mm～200mm, is best with 100mm～150mm;
Said honeycomb substrate 3 is a right cylinder with clear opening 10, and its surface has microvoid structure, in order to immobilized cell.The external diameter of honeycomb substrate 3 should be able to match with the internal diameter of interior pipe 2, can adopt inorganic materials to make as pottery or resistant to elevated temperatures organic materials;
Said clear opening 10 can be a square hole, also can be polygonal holes such as circular hole or hexagonal hole;
In the pipe 2, leave space 11 between the bottom surface of interior pipe 2 and the honeycomb substrate 3 in honeycomb substrate 3 is seated in, interior pipe 2 can adopt conventional mechanical means, as be fixed on the inwall by housing 1 by support 6;
This reactor is operation like this: enchylema or enzyme liquid are sent into reactor, it is fixed on the honeycomb substrate 3, substrate enters reactor by substrate import 5, pipe 2 in its liquid level should be higher than, pressurized air enters interior pipe 2 through aerator 7 by tuyere 8, causes the inside and outside density of liquid of pipe poor, liquid is flowed at the reactor internal recycle react, unnecessary gas then can be discharged by venting port 4.After reaction finished, reaction product can export 9 by product and discharge.
Do not have foam for making, can a foam separator be set at internal vent ports 4 places of housing 1, as silk screen separator or mechanical defoaming device etc. by venting port 4 expellant gas.
By above-mentioned disclosed technical scheme as seen, the said reactor of the utility model combines the strong point of present various bio-reactors, and have comparatively significant advantage: mass transfer effect is good, and resistance to flow is little.Compare with existing fluidized bed bio reactor, its reaction efficiency can improve 20%～30%, and resistance only is 15%～25% of a filling bed type.For a kind of bio-reactor, especially can be used for the biochemical treatment of waste water with wide application prospect.
