Description

The spirulina photosynthetic reactor

The utility model relates to the device that little algae is cultivated production, particularly is applicable to the device of the cultivation production of spirulina photosynthetic response and algal biomass.

Blue-green algae spirulina (Blue-green Alga, Spirulina Spp.) is a kind of novel microprotein resource.This algae is recommended as " human optimal food " owing to contain the nutrient substance of multiple human body needs such as very high protein, amino acid, VITAMIN, unsaturated fatty acids, polysaccharide and mineral substance by Food and Argriculture OrganizationFAO (FAO), industrial development tissue (UNIDO) etc.1985,, take the lead in having set up first batch production Da Chi of China and cultivate production system with academy of agricultural sciences, the Jiangxi Province spirulina subject study group headed by the inventor.After this, similarly device is promoted in the whole nation.Da Chi cultivates and to have that floor space is big, cost of investment is high, energy consumption is big and the problem such as be subjected to that climate influences of production throughout the year.In recent years, CN1098246A releases a kind of spirulina production method and device, and it adopts irrigation canals and ditches to add stirring means; Other has a kind of CN2084288U spirulina enclosed streamline breeding device, and it adopts transparent plastic film tube, the method for blowing air in pipe.These methods are compared with conventional Da Chi production standard, and the former still exists floor space big, produce problems such as being subjected to the climate condition influence; The latter is still unresolved when SPIRULINA CULTIVATION, because the oxygen intoxication problem of accumulating that the photosynthetic product oxygen of frustule takes place, and the pipeline technical problems such as difficulty and Winter protection difficulty of when summer high temperature, dispelling the heat.Problems such as above standard also because pipeline is the plane laying, has only the upper strata single face can be subjected to light, therefore still exists light-receiving area little, and the efficiency of light energy utilization is not high.

The purpose of this utility model, be to overcome the problems referred to above that exist in the existing spirulina production technology standard, it is very little to design a kind of floor space, energy controlled temperature and illumination, but all-weather production, can carry out high-level efficiency photosynthesis, can in time supply with and make full use of carbonic acid gas, can in time discharge the photosynthetic reactor of the oxygen that produces in the photosynthetic response process.With this reactor multiple-unit combination, can carry out mcroorganism amount continuous production, be particularly useful for production higher-grade food, doctor

The industrialized unit of medicine level spirulina.

The purpose of this utility model adopts following design implementation:

Photosynthetic reactor of the present utility model is made of photosynthetic response tower and three-dimensional double flat spin formula pipeline.The body of the tower of this reactor and pipeline are made of the height light transmissive material.Be provided with venting hole at the body of the tower top in order to get rid of oxygen, reacting pipe is introduced by tower top in the drain pipe upper end, and the drain pipe lower end places the middle and lower part of tower, liquid-inlet pipe is introduced the tower from the top of tower, the bubbling plate is established at the tower middle part, establishes heat exchanger in the tower bottom, is provided with CO at tower bottom ₂Air injection pipe, the design are taked three-dimensional double flat spin formula closed circulation pipeline, are furnished with suction pump, liquid-outlet valve and leakage fluid dram.

Effect of the present utility model is remarkable, and it has overcome, and conventional Da Chi production standard floor space is big, and energy consumption is big, and productive rate is low, and can not be golden the weather drawback of producing.It can provide the required luminous energy of photosynthetic response, fully satisfy frustule to CO by the comprehensive natural light that utilizes ₂Needs, and can in time discharge dissolved oxygen in the deleterious nutrient solution, also owing to be provided with cold/heat exchanger controlled temperature, so the production efficiency height, this reactor can be stopped infecting of all the extraneous heteroplasia things and the various chemical pollution factors owing to be that totally enclosed circulation continuous production is cultivated.So sanitary condition is good, is specially adapted to production higher-grade food, pharmaceutical grade product.

As seen from the figure, this reactor constitutes (omitting the partly middle of pipeline among the figure) by reaction tower and double flat spin formula reacting pipe.Reactor body of the tower and pipeline are made of the high transmission rate material.Top at tower 4 is provided with venting hole, in order to get rid of the oxygen that is produced in the photosynthetic response, reacting pipe is introduced in drain pipe 2 upper ends from tower top, the lower end places the tower middle and lower part, liquid-inlet pipe 3 is introduced in the tower on the top of tower 4, tower 4 pars intermedias are provided with bubbling plate 5, are provided with heat exchanger 8 in tower 4 bottoms, are provided with CO at tower bottom ₂Air injection pipe 10, three-dimensional double flat spin formula closed conduct 15 upper and lower ends link to each other with reaction tower, are provided with leakage fluid dram 13, drawing liquid valve 11 and suction pump 12 on the bottommost pipeline of helical pipe 15.

The operational process of the utility model photosynthetic reactor is as follows: the cultivation algae and the algae liquid that actively carry out photosynthetic response in vertical double flat spin formula pipeline 15, drawing liquid valve 11 enters suction pump 12, by liquid-inlet pipe 3 bottom flowing through, be evacuated to the top of reaction tower 4, pouring is annotated and is descended.Spirulina algae liquid is at tower 4 middle parts, and the gas that is subjected to being entered by air inlet port 6 (by the bubbling plate 5 jet stirring that makes progress) is got rid of the oxygen in the nutrient solution rapidly.Reaction tower 4 also continues to provide the required luminous energy of algae growth and breeding to reach by CO simultaneously ₂A large amount of CO that air injection pipe 10 enters ₂Gas enlivens photosynthetic response and carries out.In summer, a large amount of heats of accumulating in photosynthetic reactor after the heat absorption (sending cold water to by bottom water inlet pipe 9) by heat exchanger 8, flow out from the top water outlet.Nutrient solution in the photosynthetic reactor is through drain pipe 2, and tapping valve 14 enters into flat spin formula pipeline 15.In pipeline 15, spirulina is active to carry out growth and breeding, and cell is bred in a large number and produced a large amount of oxygen, and nutrient solution flows into reaction tower through suction pump then once more from the bottom pipe that flows to suitable for reading of double flat spin formula pipeline 15, and circulation goes round and begins again.When the cultivation algae reaches certain optical density(OD), can discharge from bottom pipe leakage fluid dram 13 and gather.
