Description
Technical Field
The invention relates to the field of carbon neutralization, in particular to an industrial waste gas treatment device for realizing carbon neutralization by utilizing microalgae.
Background
Carbon neutralization (carbon neutral) refers to the measurement and calculation of the total amount of greenhouse gas emission generated directly or indirectly by enterprises, groups or individuals within a certain time, and the emission of carbon dioxide generated by the enterprises, the groups or the individuals is counteracted through the forms of tree planting, energy conservation, emission reduction and the like, so that the zero emission of the carbon dioxide is realized. In many industrial processes, large amounts of waste gases containing carbon dioxide are produced, and direct emissions cause greenhouse effects. Therefore, carbon dioxide in industrial waste gas needs to be removed, which is also an important means for realizing carbon neutralization.
The common industrial carbon dioxide waste gas treatment methods mainly comprise three methods, namely physical landfill, chemical absorption and biological treatment. The potential influence and harm of physical landfill on the earth crust cannot be eliminated; the commonly used chemical adsorption reagent has small selectivity, large corrosivity and complex application equipment. These potential disadvantages of physical and chemical methods are limiting their widespread use. As an important buffer valve for maintaining the carbon circulation of the earth's sphere, microalgae is taken as a representative photosynthetic organism, and carbon dioxide can be quickly absorbed; provides a good idea for solving the problem of carbon emission in the tail gas and utilizing the tail gas. The microalgae can convert carbon dioxide into oxygen and sugar through photosynthesis by treating industrial carbon dioxide waste gas, and can promote the growth of the microalgae, and can be used for pharmacy, food, animal culture and the like. However, the existing technology for treating carbon dioxide by using microalgae generally introduces carbon dioxide into a cylindrical culture container and then performs photosynthesis, which results in: firstly, enough light cannot be obtained by overlapping the microalgae, and the photosynthesis efficiency is reduced; secondly, the photosynthetic efficiency is reduced due to the fact that the concentration of carbon dioxide is lower and lower. Therefore, the prior art is not efficient in treating the exhaust gas containing carbon dioxide.

Detailed Description
The invention discloses an industrial waste gas treatment device for realizing carbon neutralization by utilizing microalgae, and a person skilled in the art can use the content for reference and appropriately improve the technical details for realizing. It is expressly intended that all such similar substitutes and modifications which would be obvious to one skilled in the art are deemed to be included in the invention. While the methods and applications of this invention have been described in terms of preferred embodiments, it will be apparent to those of ordinary skill in the art that variations and modifications in the methods and applications described herein, as well as other suitable variations and combinations, may be made to implement and use the techniques of this invention without departing from the spirit and scope of the invention.
The applicant researches and discovers that: the existing method for treating carbon dioxide in industrial waste gas by using microalgae has the following defects: firstly, after carbon dioxide is introduced into the microalgae culture container, the carbon dioxide is replenished after being consumed to a certain degree, so that the concentration of the carbon dioxide is reduced, and the photosynthesis efficiency is reduced. Secondly, the culture container is mostly long cylindricality, leads to little algae to pile up layer upon layer, and some little algae can't obtain sufficient illumination, and photosynthesis efficiency descends. The first point and the second point cause a decrease in the efficiency of photosynthesis, and thus a decrease in the efficiency of carbon dioxide absorption.
Accordingly, an embodiment of the present invention provides an apparatus for treating industrial waste gas using microalgae to achieve carbon neutralization, as shown in fig. 1 and 2, the apparatus including: the microalgae culture container 1 is a narrow and high flat container, the height of the microalgae culture container 1 is less than 0.2m, the bottom surface 3 of the microalgae culture container 1 is parallel to the horizontal plane, and the area of the bottom surface 3 is more than 2m2The top surface 2 of the microalgae culture container 1 is obliquely arranged relative to the horizontal plane and projects on the horizontal planeThe top surface 2 is coincident with the bottom surface 3 and used for light source incidence is made of transparent material with preset light transmission performance; the bottom surface 3 is provided with an array micropore 4 for introducing carbon dioxide, the array micropore 4 is connected with a carbon dioxide preparation chamber 5, the carbon dioxide preparation chamber 5 is connected with a first pipeline 6, and the first pipeline 6 is used for introducing carbon dioxide; the top surface 2 is connected with the gas vent 7 on the slope top, and gas vent 7 is connected with the oxygen adsorption tank 9 that loads the oxygen adsorbent through second pipeline 8, and oxygen adsorption tank 9 is connected to first pipeline 6.
The device also includes a control module for:
and opening the array micropores 4 to introduce carbon dioxide into the microalgae culture container 1.
Wherein, the carbon dioxide is obtained after the industrial waste gas is subjected to multiple filtration. The gas flow diagram of the device provided by the embodiment of the invention is shown in fig. 2, wherein the solid line arrow in fig. 2 is the carbon dioxide flow diagram, and the dotted line arrow is the oxygen flow diagram. The carbon dioxide enters the microalgae culture container 1 to generate oxygen through the photosynthesis of the microalgae, the oxygen and the residual carbon dioxide enter the oxygen adsorption box 9 through the exhaust port 7, the oxygen is absorbed by the oxygen adsorbent, and the residual carbon dioxide enters the first pipeline 6 to form a cycle.
It should be noted that microalgae refers to a microscopic population of algae whose morphology can only be discerned under a microscope. Microalgae generally refers to a general term for microorganisms that contain chlorophyll a and are capable of photosynthesis, and belongs to a group of protists. Microalgae cultured or produced in large quantities by biotechnology belong to 4 phyla: cyanophyta, chlorophyta, chrysophyta and rhodophyta. Microalgae can undergo photosynthesis to treat carbon dioxide in industrial waste gases. The array of micro-wells 4 is uniformly arranged as shown in fig. 1 and 2 so that most of the micro-algae can be exposed to carbon dioxide, thereby providing sufficient oxygen to enhance photosynthesis.
Optionally, in the embodiment of the invention, the microalgae is anaerobic microalgae and has high temperature resistance.
The anaerobic microalgae is adopted because carbon dioxide gas filtered from industrial waste gas is introduced, and the carbon dioxide has high purity and extremely low oxygen content. The high temperature resistance is because industrial waste gas generally has higher temperature, and microalgae which cannot resist high temperature are difficult to survive.
Optionally, in a specific embodiment, the top surface 2 of the microalgae cultivation container 1 is made of a transparent material with high light transmittance, such as glass or polyvinyl chloride. The transparency and the high light transmittance can ensure that the microalgae in the microalgae culture container 1 can be sufficiently illuminated.
Alternatively, in one embodiment, when the area of microalgae culture vessel 1 above bottom surface 3 is in units of the same order (e.g., meters and cubic meters); narrow high flat containers are considered when the ratio of their height to the area of the bottom surface 3 is not more than one tenth. Such a structure can increase the contact area of the microalgae in the microalgae cultivation vessel 1 with light when the light irradiates the microalgae from the top surface 2, thereby enhancing photosynthesis. The embodiment of the invention is also suitable for large narrow and high flat-type containers.
Optionally, the apparatus further comprises: a multiple filter connected to the first pipe 6;
and the multiple filters are used for filtering the industrial waste gas to obtain carbon dioxide.
It should be noted that the industrial waste gas contains other harmful gases besides carbon dioxide, which may damage the microalgae, and therefore, it is necessary to filter the industrial waste gas to remove other toxic and harmful gases. Not only can the microalgae be ensured not to be damaged, but also the pollution of toxic and harmful gases to the environment is reduced.
Optionally, the apparatus further comprises: a first gas rate sensor provided at the junction of the oxygen adsorption tank 9 and the first pipe 6 and a second gas rate sensor provided at the junction of the multiple filter and the first pipe 6;
a first gas rate sensor for detecting a first exhaust rate of the oxygen adsorption tank 9 to the first duct 6;
a second gas rate sensor for detecting a second gas discharge rate of the multiple filter to the first duct 6.
The first gas rate sensor and the second gas rate sensor are used for detecting the exhaust rate, so that the gas circulation breakdown in the device caused by too fast exhaust rate is avoided, for example, the device is boosted and even damaged due to the fact that the carbon dioxide is absorbed obviously less than the exhaust carbon dioxide.
Optionally, the control module further includes: a ventilation rate control unit;
and the aeration rate control unit is used for adjusting the second exhaust rate according to the first exhaust rate so as to ensure that the rate of introducing the carbon dioxide into the microalgae culture container 1 by the first pipeline 6 is maintained within a preset range.
It should be noted that the rate of carbon dioxide entering at the first and second exhaust rates should not be greater than the rate of carbon dioxide consumption by photosynthesis of the microalgae.
Optionally, the apparatus further comprises: the microalgae collector is connected with the microalgae culture container 1;
and the microalgae collector is used for collecting the microalgae in response to the maturation of the microalgae.
Specifically, the microalgae collector is arranged below the microalgae culture container 1, and when the microalgae is mature, the microalgae culture container 1 discharges the liquid in the container into the microalgae collector. The microalgae collector is used for separating microalgae from the culture solution, the microalgae are harvested, and the culture solution is recycled.
It is worth mentioning that the mature microalgae have a wide application field, such as beauty and cosmetics, nutritional health food, bait and feed.
Optionally, the micro-wells 4 are all one-way gas valves, and have the characteristics of allowing carbon dioxide to enter the microalgae culture container 1 and not allowing liquid or gas in the microalgae culture container 1 to enter the carbon dioxide preparation chamber 5.
It should be noted that the array micropores 4 are all one-way air valves, which can ensure that the liquid backflow condition does not occur, resulting in damage to the device provided by the embodiment of the present invention.
In the embodiment of the invention, the bottom surface 3 of the microalgae culture container 1 is provided with the array micropores 4 for introducing carbon dioxide, the array micropores 4 are connected with the carbon dioxide preparation chamber 5, the carbon dioxide preparation chamber 5 is connected with the first pipeline 6, and the first pipeline 6 is used for introducing carbon dioxide; inclination of the top surface 2The top end is connected with gas vent 7, and gas vent 7 is connected with the oxygen adsorption tank 9 that loads the oxygen adsorbent through second pipeline 8, and oxygen adsorption tank 9 is connected to first pipeline 6.

Because the first pipe 6 is continuously filled with carbon dioxide (including the carbon dioxide which enters the circulation and the carbon dioxide which is newly filled) so as to ensure that the microalgae in the microalgae culture vessel 1 has enough carbon dioxide for photosynthesis, compared with the prior art, the efficiency of carbon dioxide treatment is not reduced due to the reduction of the carbon dioxide concentration. The microalgae culture container 1 of the embodiment of the invention is a narrow and high flat-type container, the height of the microalgae culture container 1 is less than 0.2m, the bottom surface 3 of the microalgae culture container 1 is parallel to a horizontal plane, and the area of the bottom surface 3 is more than 2m2The top surface 2 of the microalgae culture container 1 is obliquely arranged relative to the horizontal plane, the projection on the horizontal plane is coincided with the bottom surface 3, and the top surface 2 for light source incidence is made of a transparent material with a preset light transmission performance. The embodiment of the invention adopts the narrow and high tiled container, can effectively increase the contact surface of the microalgae and light, has the transparent top surface 2 and good light transmission performance, and can ensure that the microalgae can obtain sufficient illumination, enhance photosynthesis and accelerate the treatment efficiency of carbon dioxide. In the embodiment of the present invention, the top surface 2 is connected to an exhaust port 7 at the inclined top end thereof. Therefore, the gas (carbon dioxide and oxygen) in the microalgae culture container 1 can flow towards the inclined top end along the inclination of the top surface 2, so that the gas is easier to discharge out of the microalgae culture container 1, and the exhaust pipeline is ensured not to block illumination. Both of these can further enhance photosynthesis and accelerate carbon dioxide treatment. According to the embodiment of the invention, the microalgae culture container 1 is introduced and the array micropores 4 are adopted, so that sufficient contact between carbon dioxide and microalgae can be ensured, and photosynthesis is enhanced.
