In some embodiments, the target gas may be carbon dioxide, nitrogen, oxygen, or the like. In some embodiments, the plant may include angiosperms (e.g., roses, pears, cherries, etc.), gymnosperms (e.g., pines, cypresses, maidenhair, torreya, yew, etc.), bryophytes (e.g., cucurbits, dictyophora, liverwort, griseum, dictamnus, rhodobryum, dictyophora, dictamnus, etc.), ferns (Ceratopteris viflora, Adenophora tetraphylla, Ceratopteris viflora, etc.), and the like that may be artificially cultivated. Algae may include green algae (chlorella, scenedesmus, oocystis, fibrophyceae, onchocerca, gossypium hirsutum, cladophora, etc.); diatoms (Cyclotella, Phoenix, Cyanophyta, Botrytis, etc.); blue-green algae (microcystis, anabaena, cyanobacteria, Oscillatoria, Schizochytrium, Spirulina, etc.); euglena (Euglena viridis, Euglena capsulata, Euglena fusca, etc.); dinoflagellates (gymnodinium, dinoflagellate, etc.); yellow algae (Bothrina, etc.); cryptophyceae (cryptophyceae, etc.); golden algae (small golden trichlorfon, golden pennycress, clockweed, Pandalus xanthioides, etc.) can be artificially cultured. The mixed gas is a gas containing a target gas. In some embodiments, the mixed gas may be a gas comprising the extraction species and the target gas. Wherein the extraction substance is a substance for extracting the target gas. For example, when the target gas is carbon dioxide, the extraction material may include one or more of alcohols (e.g., methanol, ethanol, propanol, 2-methyl-2-propanol), hydrocarbons (e.g., n-pentane), fluorinated hydrocarbons, ketones, esters, ethers, and siloxanes. The mixed gas is a gas comprising carbon dioxide and one or more of alcohols, hydrocarbons, fluorinated hydrocarbons, ketones, esters, ethers, siloxanes.

In some embodiments, the mixed gas may be obtained using an extraction substance based on the target gas enrichment module 1. The details are as follows.

The target gas enrichment module 1 may include a target gas selective permeation material, wherein the target gas selective permeation material is a single pass material, and the target gas enrichment module 1 may be divided into a high concentration unit and a low concentration unit using the target gas selective permeation material. Feeding an original gas from a low-concentration unit, and obtaining a first target gas in a high-concentration unit through a target gas selective permeation material; based on the first target gas, an extraction substance is added to the high concentration unit, and a mixed gas can be obtained. Wherein, the target gas selection material is a single-pass material which can pass through the target gas. For example, the target gas is carbon dioxide, and the target gas selective permeation material may be one or more of microporous alumina, microporous carbon, microporous silica, microporous perovskite, zeolite, and hydrotalcite.

In some embodiments, the raw gas, for example, air, is introduced into the low concentration unit of the target gas enrichment module 1, other gases in the air are filtered under the action of the target gas selective permeation material, carbon dioxide enters the high concentration unit from the low concentration unit to obtain a first target gas, and the concentration of carbon dioxide in the high concentration unit is increased under the action of the extraction substance, so as to obtain a mixed gas mixed with the extraction substance and carbon dioxide.

The separation module 2 is used for separating the mixed gas to obtain the target gas. As can be seen from the above, when the target gas is carbon dioxide, a mixed gas in which carbon dioxide and an extraction substance are mixed is obtained by the target gas enrichment module 1, and the extraction substance may be alcohols, for example: methanol, ethanol, propanol, 2-methyl-2-propanol, and the like. Depending on the nature of the extraction substance, a condenser may be used to separate the target gas and the extraction substance. Under the action of the condenser, the extraction substance is gradually liquefied along with the temperature reduction, carbon dioxide gas is discharged, and the liquefied extraction substance is gradually gasified after leaving the separator and returns to the target gas enrichment module 1 to form a circulation. In some embodiments, the separation module 2 may also include a still and a compressor.

Transmitting the target gas to the biological culture module according to a preset concentration threshold. The preset concentration threshold value can be set manually or obtained by counting historical data. In some embodiments, the preset concentration threshold may be a threshold interval or a single value. In some embodiments, the target gas meeting the concentration threshold interval may be transmitted to the biological culture module, the target gas greater than the maximum value of the concentration threshold interval may be mixed with air and then transmitted to the biological culture module, or the target gas less than the minimum value of the concentration threshold interval may be enriched and separated again and then transmitted to the biological culture module. For more description of the biological culture module, reference may be made to fig. 3, fig. 4 and the related description thereof, which are not repeated herein.

As shown in fig. 3, the biological growth module may include a plurality of first growth units 3.

In some embodiments, the biological growth module comprises a plurality of first growth units 3, said first growth units 3 being connected in series by a main conduit from high to low according to a preset concentration threshold, and the output of the separation module 2 is connected to the input of each first growth unit 3 by a bypass conduit. As shown in fig. 3, in some embodiments, the output end of the separation module 2 and the output end of each first culture unit 3 are provided with a target gas concentration detection device 4, and the target gas concentration detection device 4 is used for detecting the target gas concentration output by the corresponding output end. For example, the target gas concentration detection device 4 is a carbon dioxide detection device that detects the concentration of carbon dioxide gas output from the corresponding output terminal. As shown in fig. 3, in some embodiments, a switching device 5 is provided on the main pipe at the input end of each first culturing unit 3; on the bypass pipeline, a switch device 5 is arranged at the joint of the input end of each first culture unit 3 and the bypass pipeline. The delivery of the target gas to each of the first culturing units 3 can be controlled by jointly controlling the switching devices 5 on the bypass line and the main line.

The output end of the second culture unit 6 is also provided with a target gas concentration detection device 4 for detecting the target gas concentration output by the corresponding output end.

In some embodiments, the target gas may be delivered to the biological growth module according to a preset concentration threshold.

In some embodiments, delivering the target gas to the biological growth module includes the following steps.

Step 1: judging whether the input target gas concentration value belongs to a target gas concentration interval of the current first culture unit 3, if so, executing the step 2, if so, executing the step 3, and if not, judging the next stage and executing the step 1, wherein the maximum value of the target gas concentration interval of the current first culture unit 3 is larger than the maximum value of the target gas concentration interval of the current first culture unit 3; step 2: inputting the target gas to the current first culture unit 3; and step 3: and returning to the previous stage and executing the step 1. Further comprising: and 4, step 4: judging whether the input target gas concentration value belongs to a target gas concentration interval of the first-stage first culture unit 3, if so, executing the step 5, if so, executing the step 6, and if not, returning to the enrichment module and executing the step 4; and 5: inputting the target gas to the first-stage first culture unit 3; step 6: after the air is introduced, step 4 is performed. In some embodiments, the first culture unit 3 is connected in parallel with the second culture unit 6, and the above steps are also applicable to the second culture unit 6, and are not described herein.

Taking the target gas as carbon dioxide as an example, after high-concentration carbon dioxide is output from the separation module 2, the carbon dioxide sensor reads the concentration of the currently output carbon dioxide in real time, the system analyzes the output concentration, and if the concentration is in the concentration interval of the first-stage culture unit (including the first culture unit 3 and/or the corresponding second culture unit 6), the switch device 5 is controlled to feed the output carbon dioxide gas into the first-stage culture unit. When the concentration is higher than the upper limit of the concentration interval of the first-stage culture unit, the carbon dioxide gas is conveyed from the bypass to the input port of the first-stage culture unit through the change-over switch device 5 and then is judged, and if the carbon dioxide gas is in the concentration interval of the first-stage culture unit, the carbon dioxide gas is conveyed to the input port of the first-stage culture unit and is absorbed again. If the concentration is less than the concentration interval of the primary culture unit, returning to the target gas enrichment module 1, increasing the concentration of the target gas through the target gas enrichment module 1 and the separation module 2 again, judging, and repeating the above operations. In some embodiments, it is determined whether the current carbon dioxide concentration value belongs to a target gas concentration interval of the current culturing unit (the first culturing unit 3 and/or the corresponding second culturing unit 6), and if so, the carbon dioxide gas is input to the current culturing unit; if the concentration interval is larger than the maximum value of the concentration interval of the current culture unit, returning to the previous culture unit, judging the previous culture unit, and if the concentration interval is smaller than the minimum value of the concentration interval of the current culture unit, judging the next culture unit and repeating the operation. The target gas is transmitted to different culture units through different concentrations, so that the target gas is fully utilized, the utilization rate of the target gas is improved, and the loss is reduced.
