Description

A kind of with CO 2Tower both culturing microalgae device for raw material
One, technical field
The utility model relates to a kind of with CO 2Be the tower both culturing microalgae device of raw material, it belongs to the biochemical industry apparatus field.
Two, background technology
When previous important environmental problem is Global warming, its immediate cause is CO in the atmosphere 2Increase with other greenhouse gases concentration, and in all greenhouse gases, CO 2Contribution to Greenhouse effect accounts for 60%.Reduce greenhouse gas emission, carry out CO 2Capture and seal up for safekeeping and stand in the breach.Although the Kyoto Protocol fs does not require China and reduces discharging, can not cause direct influence to China's economy.But China's subordinate phase can not be enjoyed the row's of exempting from treatment again, if hold fire, world's emission reduction tasks also can not be finished.Has only leading exploitation CO 2Capture and seal technology up for safekeeping and equipment just can be provided for a rainy day as tachnical storage, fulfil the solemn commitment of reduction of discharging simultaneously again guaranteeing that social economy increases.CO 2The technology of recovery technology mainly contains physical absorption method, chemical absorption, membrane sepn, freezing fractional separation, molecular sieve adsorption, float stone absorption and little algae biological process etc., but the first six kind method reclaims back CO 2Need seal up for safekeeping, utilize little algae biological process can realize CO simultaneously 2Capture and fixing and by-product biomass energy, have environment, the energy and resource comprehensive effect.
Israel scim biotech company developed a new technology in 2007, utilized the carbonic acid gas cultivating seaweed of power station discharging, and then therefrom produced biofuel.They had set up tentative marine alga farm in an experimental farm in Ash clone power station in 2004.This farm is made up of 8 marine alga ponds, takes up an area of 1/4 acre.Near the partial fume that discharges of a tame coal power generation factory be delivered directly in the marine alga pond, the carbonic acid gas in the flue gas has not only promoted the growth of marine alga after being absorbed by marine alga effectively, has also reduced greenhouse gases simultaneously.Other objectionable impuritiess in the flue dust are then purified by a special filtering system.Through cultivating, the marine alga growing way is swift and violent, and output improves greatly, and this provides the raw material guarantee for produce biofuel with marine alga." discharge production biofuel " technology of GreenFuel company adopts marine alga that the CO2 of power-plant flue gas and the discharge of other CO2 continuous blow-down sources is carried out recycle.In Redhawk power plant, the pipeline of particular design is used to capture and transport the CO2 discharge from chimney, sends into the special container that contains marine alga.Exist under the sunlight conditions, marine alga consumes CO2.In case marine alga increases and obtains receipts, its starch just can be converted into ethanol, and its mixtinite can be converted into biofuel, and its albumen can be converted into domestic animal and use gourmet food simultaneously.
In the world, the micro-algae large-scale artificial culture mainly contains open pond and closed photobioreactor two class modes at present.Open cultivation (as circulation runway pond) is simple relatively, investment is low, but this mode culture condition variation greatly, and little algae productive rate is low, and has serious biological pollution.Closed photo bioreactor term perennate is long, can keep higher algae liquid concentration, can reduce the cost of gathering to a certain extent, can control culture condition, to be easier to the productive rate controlling biological pollution, cultivate little algae higher, though investment cost is relatively large, become this field research and development main trend.
The closed photo bioreactor form mainly contains vertical pillar (as airlift reactor), tubular type, board-like and other specific type (as the photoconductive fiber bioreactor) at present.Airlift reactor provides algae liquid mobilization force, helps molten carbon deoxidation, and less to the shearing action of frond, and power consumption is also little, has solved dissolved oxygen accumulation problem.The unit volume productive rate and the caliber of tubular reactor have direct relation.The large volume productive rate is more little more for caliber.Reducing of caliber has negative impact to the amplification of reactor, major limitation the increase of cumulative volume of tubular type bioreactor.The plate-type reactor optical path length is too narrow, has limited the amplification potentiality of reactor widely.The wood of manufacturing into of photoconductive fiber bioreactor is extremely expensive, is difficult to be applied to little algae at foreseeable future and commercially produces.
Three, summary of the invention
The purpose of this utility model provides a kind of with CO with regard to being to avoid the weak point of above-mentioned technology 2Be the tower both culturing microalgae device of raw material, it is mainly by CO 2Compositions such as gas inlet, breed tower shell, column plate, riser, calotte, downtake, overflow weir, dividing plate, tail gas outlet.Form a tower section from culturing the beginning of tower shell bottom every 3-10 layer column plate, culture tower and be divided into 2～50 tower sections; Each tower pars infrasegmentalis is provided with a CO 2Gas inlet, top are provided with a tail gas outlet; The intersegmental gas passage of tower separates with dividing plate, and liquid is communicated with by downtake; Culture the tower bottommost and be provided with liquid extraction mouth, top is provided with the liquid inlet; Every layer of column plate bottom is equipped with power lights; Every layer of column plate top is equipped with a plurality of riseies, and inlet end has downtake, and exit end is provided with overflow weir; The percentage of open area of riser accounts for 6%～50% of column plate cross section, and riser is straight pipe type, Taper Pipe type, cuboid or prismatoid, and the riser inlet is flat mouthful or splayed, and the riser outside is provided with calotte; The perforate of calotte upper top, hole shape is circular hole, bar hole, diamond hole or shutter shape etc., percentage of open area is more than or equal to the percentage of open area of column plate.
Four, description of drawings
Accompanying drawing 1 is a structural representation of the present utility model, and accompanying drawing 2 is the structural representation of riser inlet.
The drawing of accompanying drawing is established bright as follows:
