2Problems such as the not high and culture efficiency of utilization ratio is low have restricted seriously that little algae produces and the high speed development of little algae biotechnology industry.Other has a kind of employing canned, its advantage be for keeping algae kind purity pollution-free, can scale operation, but because cost height, maintenance are unpicked and washed, installation difficulty is big, infringement degree of one-tenth height of parts needs repairing and waits improper for a long time and be difficult to big area and promote.Domestic and international in recent years many scholars have carried out a series of research at this respect problem, especially utilize the research of the little algae of photoreactor high-efficient culture to obtain certain achievement.At present representative bioreactor mainly contains following several: 1. pipeline reactor; 2. plate-type reactor; 3. optical fiber reactor; 4. light-emitting diodes pipe reactor etc., these photoreactors are the trend of following little algae scale operation with optimal control and higher output and showed bright development prospect.But still there are some problems in practice in they,, gaseous interchange low as the efficiency of light energy utilization is not smooth etc., the high energy consumption of especially present pipeline bioreactor commonly used both at home and abroad, expensive, it is big to keep in repair, unpick and wash difficulty, the long subject matter that has become the development of restriction bioreactor of time consuming time.
Summary of the invention
The purpose of this invention is to provide a kind of both culturing microalgae closed reactor that can realize that high-density, high yield, less energy-consumption, low-cost cultivation require.
The objective of the invention is to be achieved through the following technical solutions:
The present invention includes: reactor, the algae liquid supplementing device, the carbonic acid gas delivery system, mix the gas-liquid switch, nutritive medium is carried system and algae liquid harvesting system, the outlet of algae liquid supplementing device and carbonic acid gas delivery system all carries the inlet of system to be connected with nutritive medium, nutritive medium carries the outlet of system to be connected with the inlet that mixes the gas-liquid switch, the outlet that mixes the gas-liquid switch is connected with the input aperture of reactor, the circulation port of reactor is connected with the circulation port that mixes the gas-liquid switch, the algae liquid delivery port of reactor is connected with algae liquid harvesting system, and a sidewall of reactor is provided with Movable valve.
Reactor of the present invention can be three-dimensional, three-dimensional, multilayer, in establish cycle partition and annular channel, adopt acrylic transparent adhesive tape or glass to make, can realize high-density, high yield, less energy-consumption, low-cost cultivate require in, mainly at light source, CO
2Supply respect is innovated, and has solved the problem of three aspects emphatically: the one, and light source is comprehensive to be replenished; The 2nd, the algae liquid recycle stream is moved more become rationally, replenish the required CO of algae simultaneously
2The 3rd, solve the problem of aspects such as can in the shortest time, keeping in repair, unpick and wash, and helped large-scale development.
The present invention adopts the three-dimensional structure, and sensitive surface extensively and comprehensively, all claims, remove clean convenient, only need existing duct type device ten/once time can finish.In microorganism algal grown process, adopt gas-liquid mixed (carbonic acid gas and algae nutrient solution), allow more accelerated development of algae grows.
Closed reactor major advantage of the present invention is: each three-dimensional vertical reactor is a unit, and the side is provided with Movable valve to be opened/closed, can open Movable valve when the needs repair and maintenance, cleans arbitrarily, conveniently saves time again, has reduced labour intensity.Can make up by many units as batch production production, more can save energy (power).
The present invention has broken through the pattern of existing closed conduit reactor, has kept the habit of circular flow, courageously adopts gas-liquid mixed, and effectively utilizes electromagnetic induction principle with water demineralization, and the growth of chlorella is multiplied.
Description of drawings
Fig. 1 is the structural representation of the both culturing microalgae closed reactor that provides of the specific embodiment of the invention.
Embodiment
A kind of both culturing microalgae closed reactor (see figure 1) that the specific embodiment of the invention provides, comprise: reactor 1, algae liquid supplementing device 16, carbonic acid gas delivery system 17, mix gas-liquid switch 18, nutritive medium is carried system 19 and algae liquid harvesting system 22, the outlet of algae liquid supplementing device 16 and carbonic acid gas delivery system 17 all carries the inlet of system 19 to be connected with nutritive medium, nutritive medium carries the outlet of system 19 to be connected with the inlet that mixes gas-liquid switch 18, the outlet that mixes gas-liquid switch 18 is connected with the input aperture 3 of reactor 1, the circulation port 4 of reactor 1 is connected with the circulation port 26 that mixes gas-liquid switch 18, the algae liquid delivery port 5 of reactor 1 is connected with algae liquid harvesting system 22, and a sidewall of reactor 1 is provided with Movable valve 2.
