Factory, steel mill or cement plant etc. produce the producer of CO 2 waste gas, and being used as microalgae by pipeline to draught fan system gives birth to
Long carbon dioxide source 150, so as to further reduce energy consumption and production cost.When the CO 2 waste gas concentration of producer is suitable
In the case of, above-mentioned mixing valve 157 can also be not provided with, and be directly passed through gaseous carbon dioxide in both culturing microalgae pipe 140 i.e.
Can.
With reference to figure 3, both culturing microalgae pipe 140 includes the first connecting tube 141, the second connecting tube 143 and some cultivation pipes 145,
Some cultivation pipes 145 are vertically arranged, and the cultivation upper end of pipe 145 connects with the first connecting tube 141, and lower end connects with the second connecting tube 143
It is logical.Carbon dioxide is passed through cultivation pipe 145 by above-mentioned air-breather 155 by cultivating the junction of 145 and second connecting tube of pipe 143
In.
According to production-scale difference, the cultivation pipe 145 of varying number can be set, and need to increase or decrease production
During scale, it is only necessary to control the cultivation quantity of pipe 145 between the first connecting tube 141 and the second connecting tube 143.In production, often
It is 10-1000 tons by liquid capacity control in both culturing microalgae pipe 140, to ensure the serialization and scale of production.Need to illustrate
, as needed, the above-mentioned inner capacities of both culturing microalgae pipe 140 is also less than 10 tons or more than 1000 tons.
Specifically, the top of the first tank body 110 is connected by first passage 161 with the second connecting tube 143, Guan Hezuo is being carried out
With rear, by the gravity of solution, directly can be flowed into from the second connecting tube 143 in the first tank body 110, in order to control the stream of liquid
It is dynamic, the first on-off valve 163 is provided with the second connecting tube 143.After allowing solution to enter both culturing microalgae pipe 140, it is logical to close first
Disconnected valve 163, that is, carry out photosynthesis, and is sufficiently mixed, stirred and inner-walls of duct cleaning.When need flow back transfer
When, the first on-off valve 163 is opened, under gravity, the solution containing a large amount of microalgaes passes through the backflow of first passage 161 first
In tank body 110.
The bottom of first tank body 110 is connected by second channel 165 with the first body, when air pump 130 works, the first tank
Air pressure is raised in body 110, and liquid in first tank body 110 is pumped into both culturing microalgae pipe 140 by second channel 165 by air pressure
It is interior, carry out photosynthesis.It should be noted that in other embodiments, it is above-mentioned on the premise of it can realize circulation
First passage 161 and second channel 165 can also be other set-up modes.Second tank body 120 passes through fourth lane 180 and first
Tank body 110 connects, and is passed through remaining liq in the first tank body 110 again by fourth lane 180 after flocculation, is next time micro-
Algae growth provide Nutrient medium, by this way when whole system more low water consumption, serialization.
Microalgae concentration reaches after preset value, it is necessary to which to output it flocculation, drying enough in solution in both culturing microalgae pipe 140
Product is made.Therefore in the present embodiment, the one end of the first connecting tube 141 away from the first tank body 110 and the second tank body 120 pass through the
Triple channel 167 connects.And the second on-off valve 170 is provided with third channel 167, photosynthesis and solution are being carried out to first
When tank body 110 flows back, the second on-off valve 170 remains turned-off, and after microalgae concentration reaches preset value, closes the first on-off valve 163, beats
The second on-off valve 170 is opened, solution connects a large amount of microalgaes and enters the second tank body 120, to carry out subsequently flocculation and drying operation.
Further, in order to improve the whole operating efficiency of low energy consumption microalgae culturing device adopting 100 and automaticity, at this
In embodiment, concentration sensor 171 is additionally provided with third channel 167, the concentration sensor 171 is configured to work as third channel
When solution concentration is more than preset value in 167, the second on-off valve 170 is opened.Solution in both culturing microalgae pipe 140 is set to pass through third channel
167 enter in the second tank body 120.It should be noted that in other embodiments, above-mentioned second break-make can be not provided with
Valve 170.
In the present embodiment, in order to which the microalgae of cultivation is made into finished product, also include in low energy consumption microalgae culturing device adopting 100
Drying device (not shown).Microalgae solution carries out flocculation operation after the second tank body 120 is entered, by matter liquid in microalgae solution
Separated, solution is turned again in the first tank body 110 by fourth lane 140, and remaining microalgae is carried out by the drying device
Dry.Consider to reduce energy consumption and cost simultaneously, herein from spray drying technology, save energy algae powder made from guarantee simultaneously
Quality.If in addition, having power plant or other producers to provide waste heat, microalgae is dried using waste heat low-temperature drying equipment,
Energy consumption and cost can further be reduced.
Optionally, feeding pipe 111 is also included on the first tank body 110, feeding pipe 111 is located at the top of the first tank body 110.
