Description

Technology Field

[0001] The present invention relates to a carbon dioxide generating device using seashells, and more specifically, to a device that generates carbon dioxide using seashells, which are treated as waste, instead of using conventional kerosene or gas, for the production of carbon dioxide required in vertical plant factories that grow plants indoors (such as in dark rooms). Background Technology

[0002] In general, photosynthesis is extremely important for the cultivation conditions of high-quality horticultural crops. It is known that the rate of photosynthesis is greatly influenced by temperature and carbon dioxide concentration. Horticultural crops absorb carbon dioxide from the atmosphere to perform photosynthesis, thereby producing assimilated products necessary for crop growth, and as the amount of photosynthetic products increases, the yield and quality of the crops often improve.

[0003] Accordingly, vertical plant factories and the like are equipped with carbon dioxide generating devices to supply an appropriate amount of carbon dioxide to growing crops. For example, Korean Registered Patent No. 10-1361152 discloses a carbon dioxide generating device for plant cultivation.

[0004] Specifically, the aforementioned prior art is characterized by using diesel and kerosene as fuel, being equipped with an exhaust aftertreatment device that includes a metal particulate filter to oxidize soot emitted during fuel combustion, and including a moisture condensation device as a main component that includes a heat exchanger to remove moisture contained in the exhaust gas generated from a carbon dioxide generator. However, this prior art had the problem that not only was fossil fuels, including diesel or kerosene, continuously required, but a large amount of energy was consumed for fuel combustion, and air pollutants, including carbon monoxide, were generated during incomplete combustion of the fuel, thereby having an adverse effect on the surrounding environment for the production of carbon dioxide. The problem to be solved

[0005] Accordingly, the purpose of the present invention is to provide a device that produces carbon dioxide using waste seashells, unlike conventional vertical plant cultivation industries that produce carbon dioxide necessary for plant growth using kerosene or gas. means of solving the problem

[0006] A carbon dioxide generating device using shells is characterized by comprising: a first tank in which an aqueous acid solution is stored; a second tank in which shells are stored; a reaction vessel in which the aqueous acid solution supplied from the first tank and the shells supplied from the second tank react; a third tank in which carbon dioxide obtained by chemically reacting the aqueous acid solution and the shells in the reaction vessel is collected; and a supply pipeline section including a first supply pipeline connecting the first tank and the reaction vessel, a second supply pipeline connecting the second tank and the reaction vessel, and a third supply pipeline connecting the reaction vessel and the third tank.

[0007] At this time, it is preferable that the first tank described above stores an aqueous acid solution comprising at least one of an aqueous hydrochloric acid solution and an aqueous acetic acid solution as the aqueous acid solution.

[0008] In addition, it is preferable that one or more types of shells are stored in the aforementioned second tank, and that a grinder is provided inside to process the shells by crushing them, and that the crushed shells are supplied to the reaction tank through the second supply pipe.

[0009] In addition, the carbon dioxide generating device using the aforementioned shell preferably further includes a first valve disposed on one side of a first supply pipeline to open and close the first supply pipeline, a second valve disposed on one side of a second supply pipeline to open and close the second supply pipeline, and a third valve disposed on one side of a third supply pipeline to open and close the third supply pipeline.

[0010] In addition, the aforementioned third tank is equipped with a first sensor module for sensing the concentration of carbon dioxide collected in the third tank, and it is preferable to open the third valve to supply carbon dioxide to a target when it is determined that the concentration of carbon dioxide collected in the third tank has reached a preset target concentration.

[0011] In addition, it is preferable that a discharge pipe be provided in a lower region of the aforementioned reaction vessel to discharge the byproduct generated by the reaction between the acid solution and the shell to the outside.

[0012] In addition, a second sensor module is provided in an upper region of the aforementioned reaction vessel to sense the concentration of carbon dioxide generated by the reaction between the acidic aqueous solution and the seashell, and it is preferable to detect whether the reaction in the reaction vessel has ended based on the trend of increase or decrease in the carbon dioxide concentration sensing value of the second sensor module, and to discharge the byproduct by opening the discharge pipe.

[0013] In addition, by-products discharged through the aforementioned discharge pipe are received into a separately provided discharge tank, and the discharge tank is equipped with a weight sensing sensor. If no weight increase trend is detected during a critical time, it is determined that all by-products generated in the reaction tank have been discharged, and a command to close the discharge pipe is transmitted to the control panel. Effects of the invention

[0014] According to one embodiment of the present invention, the present invention provides a device that generates carbon dioxide using seashells, which are treated as waste, instead of using conventional fossil fuels such as kerosene or gas, for the production of carbon dioxide required for a vertical plant factory that grows plants indoors (such as in a dark room), thereby enabling carbon dioxide to be generated in a more environmentally friendly way.

[0015] In addition, according to one embodiment of the present invention, the present invention not only reduces waste discharge by utilizing seashells, which were previously treated as waste, but also enables the utilization of by-products other than carbon dioxide (e.g., calcium chloride and calcium acetate) generated from the reaction between seashells and an acidic aqueous solution, thereby maximizing the efficiency of waste utilization.

[0022] The purpose of this invention is to provide a technology that is environmentally friendly and reduces the energy consumed for carbon dioxide generation by providing a device that produces carbon dioxide using waste seashells, unlike conventional vertical plant cultivation industries that use kerosene or gas to produce the carbon dioxide necessary for plant growth.

[0023] Hereinafter, a more detailed description of the present invention for achieving the above objectives will be provided with reference to the attached drawings, and multiple drawings may be simultaneously referenced to describe one or more technical features or components constituting the invention.

[0024] Referring to Figure 10A of Fig. 1, which illustrates a configuration diagram of a carbon dioxide generating device using a seashell, the present invention includes, as a main component, a first tank (11) in which an aqueous acid solution is stored, and in this first tank (11), an aqueous acid solution of either an aqueous hydrochloric acid solution or an aqueous acetic acid solution may be stored as the aqueous acid solution.

[0025] In addition, the present invention includes a second tank (12) in which shells are stored as a main component. The shells stored in the second tank (12) described above refer to the shells of shellfish such as cockles or oysters, and since the main component of these shells is calcium carbonate, carbon dioxide is generated when reacted with the acid component stored in the first tank (11), and the specific mechanism of carbon dioxide generation will be described later.

[0026] As an example of one embodiment, the second tank (12) described above of the present invention most preferably uses oyster shells having a calcium carbonate content of 90% or more, but one or more types of shells including oyster shells and shells other than oyster shells may be stored.

[0027] In addition, in one embodiment, the interior of the second tank (12) described above may further include a grinder configuration capable of cutting shells. This grinder functions to crush the shells stored in the second tank (12). When the shells are crushed in this way, the crushed shells react more actively with the acidic aqueous solution in the reaction tank (13) described later, which can help increase the efficiency of carbon dioxide production.

[0028] Next, the present invention includes, as a main component, a reaction tank (13) for reacting an acidic aqueous solution supplied from a first tank (11) with a shell supplied from a second tank (12).

[0029] As an example of one embodiment, if the acid solution supplied from the first tank (11) is an aqueous hydrochloric acid solution, it may have a mechanism like A of FIG. 2.

[0030] In other words, when calcium carbonate (CaCO3) from a seashell reacts with an aqueous hydrochloric acid solution (2HCl), solid calcium chloride (CaCl2), liquid water (H2O), and gaseous carbon dioxide (CO2) are obtained as byproducts.

[0031] In addition, as another embodiment, if the aqueous acid solution supplied from the first tank (11) is an aqueous acetic acid solution (or acetic acid), it may have a mechanism like B of FIG. 2.

[0032] In other words, the calcium carbonate (CaCO3) from the seashell reacts with an aqueous acetic acid solution (2CH3COOH) to obtain solid calcium acetate (Ca(CH3COO)2), liquid water (H2O), and gaseous carbon dioxide (CO2) as byproducts.

[0033] In addition, although not explicitly shown in FIG. 1, the present invention further includes a supply pipeline section comprising a first supply pipeline, a second supply pipeline, and a third supply pipeline.

[0034] At this time, the first supply pipe described above is configured to connect the first tank (11) and the reaction tank (13) described above, and performs the function of supplying the acid solution stored in the first tank (11) to the reaction tank (13). Next, the second supply pipe is configured to connect the second tank (12) and the reaction tank (13) described above, and performs the function of supplying the crushed shells stored in the second tank (12) to the reaction tank (13). Next, the third supply pipe is configured to connect the reaction tank (13) and the third tank (14) described above, and performs the function of transferring the carbon dioxide generated in the reaction tank (13) to the third tank (14).

[0035] Preferably, on one side of each supply pipeline including the first supply pipeline, the second supply pipeline, and the third supply pipeline described above, an electric valve including a first valve (111), a second valve (121), and a third valve (131) that performs the opening and closing operation of the first supply pipeline, the second supply pipeline, and the third supply pipeline may be further included so that the opening and closing control of the supply pipeline section may be performed remotely or according to a preset control algorithm.

[0036] At this time, the third valve (131) described above may be based on including at least two valve configurations, such as a valve installed on one side of a third supply pipeline connecting the reaction vessel (13) and the third tank (14), and a valve installed on one side of a third supply pipeline supplying carbon dioxide from the third tank to a carbon dioxide supply target, but the present invention is not limited thereto.

[0037] In addition, as another preferred embodiment of the present invention, with reference to 10B of FIG. 3, the aforementioned third tank (14) may be equipped with a first sensor module (S1) for sensing the concentration of carbon dioxide collected in the third tank (14), and when the concentration of carbon dioxide collected in the third tank (14) is determined by the first sensor module (S1) to have reached a preset target concentration, the aforementioned third valve (131) is opened to supply carbon dioxide to the supply target.

[0038] In one embodiment, carbon dioxide generated by the mutual reaction between the shell and the acid solution in the reaction tank (13) is collected in the third tank (14), and the concentration of carbon dioxide in the third tank (14) will gradually increase as shown in 1000 of FIG. 4. At this time, the first sensor module (S1) monitors the concentration of carbon dioxide present inside the third tank (14) and detects when the optimal concentration of carbon dioxide required by the carbon dioxide supply target is reached, and can supply carbon dioxide with the optimal concentration to the carbon dioxide supply target in a timely manner.

[0039] As a more specific example, if the carbon dioxide supply target is a vertical plant factory, the preset target concentration may be 700 ppm, which is the optimal carbon dioxide concentration for plant growth. Accordingly, the first sensor module (S1) can open the third valve (131) (specifically, a valve installed on one side of the third supply pipeline connecting the third tank (14) and the carbon dioxide supply target) when the concentration of carbon dioxide collected in the third tank (14) reaches 700 ppm, thereby supplying carbon dioxide of the preset concentration to the supply target.

[0040] Of course, in another embodiment of the present invention, the first sensor module (S1) and the communication module may be interconnected so that when the concentration of carbon dioxide in the first sensor module (S1) reaches a preset threshold target concentration, the communication module transmits a notification message to the control terminal indicating that the concentration of carbon dioxide has reached the threshold target concentration, and receives input from the control terminal regarding whether to open the third valve (131), thereby enabling control of the third valve (131) according to the input from the control terminal, and the present invention is not limited thereto.

[0041] In addition, in one embodiment of the present invention, a discharge pipe (140) may be additionally provided in a lower portion of the aforementioned reaction vessel (13) to discharge to the outside the byproduct generated by the reaction between the acid solution and the shell.

[0042] That is, in the present invention, by-products such as calcium chloride or calcium acetate, water, etc., generated by the reaction between the acid solution and the shell can be discharged through the aforementioned discharge pipe (140) without the need to collect them directly from the reaction tank (13), thereby increasing the ease of discharging by-products.

[0043] Of course, at this time, a fourth valve (141) similar to the first valve (111), second valve (121), and third valve (131) described above may be included on one side of the discharge pipe (140) to control the opening and closing operation of the path through which byproducts are discharged, and the present invention is not limited thereto.

[0044] In addition, as a more preferred embodiment of the present invention, with reference to 10C of FIG. 5, a second sensor module (S2) is further included in an upper part of the reaction vessel (13) to sense the concentration of carbon dioxide generated by the reaction of an acidic aqueous solution and a shell, and it may be possible to detect whether the reaction in the reaction vessel (13) is proceeding or has ended from the trend of increase or decrease of the carbon dioxide concentration sensing value measured by the second sensor module (S2).

[0045] Referring to 1100 in FIG. 6 as an example, the result of monitoring the concentration of carbon dioxide measured by the second sensor module (S2) on an hourly basis is shown.

[0046] At this time, t1 can be understood as the point at which the reaction between the shell and the acid solution begins, and t15 can be seen as the point at which the reaction between the shell and the acid solution ends, as the carbon dioxide concentration gradually decreases when viewed from the trend of increase and decrease in carbon dioxide concentration and shows a carbon dioxide concentration similar to the point at which the reaction between the shell and the acid solution begins.

[0047] Meanwhile, the trend of increase or decrease in carbon dioxide concentration measured by the second sensor module (S2) can be transmitted to the control panel, and the control panel determines whether to open the discharge pipe (140) based on the trend of increase or decrease in carbon dioxide concentration to control whether to open or close the fourth valve (141).

[0048] For example, if the reaction between the shell and the acid solution shows a decreasing trend rather than an increasing trend, and no significant change in carbon dioxide concentration is observed during a critical time (e.g., 5 minutes), the control panel determines that the reaction between the shell and the acid solution has ended and opens the fourth valve (141) installed on one side of the discharge pipe (140), thereby allowing the by-products remaining in the reaction tank (13) to be discharged as the reaction ends.

[0049] In this case, another preferred embodiment of the present invention may further include a discharge tank (15) configuration as shown in 10D of FIG. 7. Specifically, the discharge tank (15) can be understood as a storage tank in which by-products discharged through the discharge pipe (140) are received, and may be provided at the bottom of the carbon dioxide generating device.

[0050] In a more preferred embodiment, the discharge tank (15) described above may be equipped with a weight sensing sensor (S3). When a byproduct discharged through the discharge pipe (140) is transferred to the discharge tank (15), if no weight increase trend is detected for a critical time (e.g., 5 minutes), the weight sensing sensor (S3) may determine that all byproducts generated in the reaction tank (13) have been discharged and transmit a command to close the discharge pipe (140) to the control panel.

[0051] At this time, the closing command of the discharge pipe (140) can be understood as a closing command of the fourth valve (141) installed on one side of the discharge pipe (140), thereby allowing preparation for the next carbon dioxide generation reaction.

[0052] In addition, the control panel mentioned above may function to control the opening and closing of the first valve (111), second valve (121), and third valve (131) in addition to controlling the fourth valve (141) mentioned above, using a mechanism similar or identical to the control mechanism of the fourth valve (141), and the present invention is not limited thereto.

[0053] On the other hand, referring to 10000 in FIG. 8, FIG. 8 illustrates a schematic example of a carbon dioxide generating device using the seashell of the present invention as described above.

[0054] As illustrated in FIG. 8, the carbon dioxide generating device using a shell according to the present invention may include a dedicated housing, and the housing may include a first tank (11), a second tank (12), a third tank (14), and a reaction vessel (13).

[0055] In addition, as shown in FIG. 8, the first tank (11) and the reaction tank (13), the second tank (12) and the reaction tank (13), and the reaction tank (13) and the third tank (14) may be connected by the first supply pipe, the second supply pipe, and the third supply pipe. In the case of the third supply pipe (130a), one side may be connected to the reaction tank (13), while the other side may form a supply line (130b) for delivering carbon dioxide collected in the third tank (14) to the carbon dioxide supply target.

[0056] Additionally, as shown in FIG. 8, the first tank (11), the second tank (12), and the third tank (14) can be installed at a position relatively higher than the reaction tank (13) inside the housing. That is, the reaction tank (13) is located at the bottom of the first tank (11), the second tank (12), and the third tank (14), so that an acidic solution or shell can be easily supplied to the reaction tank (13) without requiring a separate pump configuration.

[0057] Of course, in other embodiments of the present invention, there may also be embodiments including a pump configuration in which an acidic aqueous solution is pumped to supply to the reaction tank (13) or a shell is pumped to supply to the reaction tank (13), and the present invention is not limited thereto.

[0058] In addition, as described above, the carbon dioxide generating device using a shell according to the present invention may include a discharge tank (15) having a structure that is interconnected with the reaction tank (13) by a discharge pipe (140) in a lower portion of the reaction tank (13). In the embodiment of FIG. 8, the discharge tank (15) is shown as being located inside the housing, but in other embodiments of the present invention, it is obvious that the discharge tank (15) may be implemented in a form that is independently installed outside the housing.

[0059] In addition, as shown in FIG. 8, the first valve (111), second valve (121), third valve (131), and fourth valve (141) are provided in the aforementioned first supply pipe, second supply pipe, third supply pipe, and discharge pipe (140), and the opening and closing operation of these valve configurations can be controlled by a control panel connected via wired or wireless connection.

[0060] In summary, according to the carbon dioxide generating device using seashells described above, according to one embodiment of the present invention, the present invention provides a device that generates carbon dioxide using seashells, which are treated as waste, instead of using fossil fuels such as conventional kerosene or gas, for the production of carbon dioxide required for a vertical plant factory that grows plants indoors (such as in a dark room), thereby enabling carbon dioxide to be generated in a more environmentally friendly way.

[0061] In addition, according to one embodiment of the present invention, the present invention not only reduces waste discharge by utilizing seashells, which were previously treated as waste, but also enables the utilization of by-products other than carbon dioxide (e.g., calcium chloride and calcium acetate) generated from the reaction between seashells and an acidic aqueous solution, thereby maximizing the efficiency of waste utilization.
