Description

[Technical Field]

[0001] The present invention relates to a cascade-type artificial reforestation device, and more specifically to a cascade-type artificial reforestation device that drops a basic-alkali mixed solution in multiple stages in the direction of gravity using a cascade type system, captures carbon dioxide in the surrounding air that comes into contact with it, and converts it into a carbon resource, thereby removing carbon dioxide from the air and converting it into other useful resources, and also capable of continuously supplying artificially purified, clean air to the surrounding atmosphere. [Background technology]

[0002] Recently, there has been a rapid increase in various natural disasters caused by climate change around the world, such as explosions, floods, and large-scale wildfires. The main cause of this increase in natural disasters is said to be the rapid increase in carbon dioxide in the atmosphere.

[0003] With global atmospheric carbon dioxide concentrations hitting a new record high in 2020, it has been predicted that carbon emissions will increase by around 16% by 2030 compared to 2010 levels, with countries' carbon emission reduction plans falling short of expectations. If this trend continues, it will be difficult to achieve the international target of limiting global temperature rise to 1.5°C above pre-industrial levels, and global temperatures could rise by 2.7°C by 2100, according to the analysis.

[0004] Additionally, the World Meteorological Organization (WMO) announced that the average concentration of carbon dioxide in the world's atmosphere in 2020 reached a new record high of 413.2 ppm, 2.5 ppm higher than in 2019. Last year's increase in carbon dioxide concentrations showed a rapid increase, exceeding the average of the past 10 years (2.4 ppm). These carbon dioxide concentrations are 149% of pre-industrial levels (1750).

[0005] Experts point out that the reason for this sustained increase in atmospheric carbon dioxide is due to the property of carbon dioxide, which remains in the atmosphere for up to 200 years once released. This property has made it increasingly necessary for the world to reduce carbon emissions more quickly in order to combat natural disasters caused by carbon dioxide.

[0006] Furthermore, the World Meteorological Organization also expressed concern that the carbon absorption capacity of land ecosystems is declining, with the Amazon region, which previously absorbed carbon, turning into a carbon emission source as a result of development promoted by the Brazilian government.

[0007] As mentioned above, carbon dioxide emissions are rapidly increasing around the world, and the need to reduce carbon dioxide emissions is recognized. However, there are limits to how effectively terrestrial ecosystems can absorb carbon dioxide.

[0008] Meanwhile, until recently, there has been active development of technologies for purifying foreign matter such as dust and particles in the air, but there has been little progress in the development of technologies that can continuously capture carbon dioxide in the air and utilize the carbon dioxide capture material generated by capturing carbon dioxide, and there is an urgent need to develop technologies to address this issue. Summary of the Invention [Problem to be solved by the invention]

[0009] The present invention has been made to solve the above-mentioned problems, and its object is to provide an artificial reforestation device that continuously reduces carbon dioxide in the air and changes the quality of the surrounding air to be clean and comfortable.

[0010] Another object of the present invention is to provide an artificial reforestation device that can remove carbon dioxide and convert it into other useful resources by using a cascade type device to drop a basic-alkali mixed solution in multiple stages in the direction of gravity, while capturing carbon dioxide in the surrounding air that comes into contact with the solution and converting it into a carbon resource.

[0011] Another object of the present invention is to provide an artificial reforestation device that measures the concentration of carbon dioxide present in the air before and after capture, and displays the reduced carbon dioxide concentration on a display unit, or provides the change in carbon dioxide concentration in the air to local governments and managers, so that the local governments and managers with jurisdiction over the area can make appropriate use of the information or take appropriate action in response to the change in carbon dioxide concentration.

[0012] A further object of the present invention is to provide an artificial reforestation device that captures carbon dioxide using a basic alkali mixed solution that overcomes the various drawbacks of the aqueous alkanolamine solution, which is a carbon dioxide absorbent widely used in conventional technologies, thereby ensuring economic efficiency compared to conventional technologies.

[0013] The technical problems to be solved by the present invention are not limited to the above-mentioned technical problems, and other technical problems not mentioned above will be clearly understood by those skilled in the art to which the present invention pertains from the following description. [Means for solving the problem]

[0014] According to one embodiment of the present invention, a cascade-type artificial reforestation device includes a cascade channel assembly having a rectangular casing in which a plurality of partitions are horizontally stacked at regular intervals in multiple stages, with left and right ends of the partitions alternately connected to each other to form a zigzag-shaped internal channel; an air inlet connected to a lower side of the cascade channel assembly to draw in ambient air and guide the drawn air to flow upward along the internal channel of the cascade channel assembly; a mixture storage unit located at the lower side of the cascade channel assembly and storing a basic-alkali mixture of specific components that undergoes a chemical reaction upon contact with air to capture carbon dioxide in the air, the mixture storage unit supplying the basic-alkali mixture to an upper part of the cascade channel assembly when air is drawn in through the air inlet unit, and guiding the basic-alkali mixture to flow downward under its own weight along the internal channel of the cascade channel assembly so as to come into surface contact with the air; and an air outlet located at the upper part of the cascade channel assembly to discharge the remaining air from which carbon dioxide has been removed via the internal channel to the surrounding environment.

[0017] According to one embodiment, a pattern is formed on the plurality of partitions of the cascade flow channel assembly, thereby increasing the contact area between the basic-alkali mixture and the drawn air.

[0018] According to one embodiment, the air intake unit is provided with at least one of a thermometer, a hygrometer, and a carbon dioxide concentration meter for measuring the temperature, humidity, or carbon dioxide concentration of the air taken in from the surroundings, and further provided with a preheater for preheating the taken in air to a temperature suitable for reaction with the basic-alkali mixed solution.

[0019] According to one embodiment, the air discharge unit is provided with at least one of a flow meter, a thermometer, a hygrometer, and a carbon dioxide concentration meter for measuring the flow rate, temperature, humidity, or carbon dioxide concentration of the air from which carbon dioxide has been removed.

[0020] According to one embodiment, a replenishment water reservoir may be further provided on one side of the mixed solution reservoir to replenish water evaporated from the basic-alkali mixed solution.

[0021] According to one embodiment, an air intake fan is further installed in a part of the air flow path of the air discharge part or the air intake part.

[0022] According to one embodiment, the basic-alkali mixture includes one or more oxides selected from the group consisting of SiO2, Al2O3, Fe2O3, TiO2, MgO, MnO, CaO, Na2O, KO, and PO3; one or more metals selected from the group consisting of Li, Cr, Co, Ni, Cu, Zn, Ga, Sr, Cd, and Pb; a crystallized synthetic zeolite made from an alumina-based raw material, a silica-based raw material, and sodium hydroxide; and one or more liquid compositions selected from the group consisting of sodium tetraborate (Na2B4O7·10HO), sodium hydroxide (NaOH), sodium silicate (Na2SiO3), potassium hydroxide (KOH), and hydrogen peroxide (HO2).

[0030] Furthermore, according to one embodiment of the present invention, the captured carbon dioxide can be used to produce sodium carbonate or sodium bicarbonate, which are useful resources.

[0035] Since the present invention can be modified in various ways and can have various embodiments, specific embodiments are shown by way of example in the drawings and will be described in detail in the detailed description.

[0036] However, it should be understood that this is not intended to limit the invention to any particular embodiment, but rather to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

[0037] In the present invention, the terms "comprise" or "have" and the like are intended to specify the presence of features, numbers, steps, operations, components, parts or combinations thereof described in the specification, and should be understood not to preclude the presence or possibility of addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

[0038] The present invention will be specifically described below.

[0039] Figure 1 is a front view showing the entire cascade-type artificial reforestation device according to one embodiment of the present invention, Figure 2a is a plan view of Figure 1, Figure 2b is a left side view of Figure 1, Figure 2c is a right side view of Figure 1, Figure 3 is a perspective view of the main parts showing a cascade flow path assembly according to the present invention, Figure 4 is a front, side and plan view of Figure 3, Figure 5a is a perspective view of the main parts showing the partition plates of Figure 3 separated, and Figure 5b is a front, side and plan view of Figure 3 separated.

[0040] 1 to 5, a cascade-type artificial reforestation device 100 according to one embodiment of the present invention includes a rectangular casing 111 and a plurality of partitions 112 stacked horizontally in multiple stages at regular intervals inside the casing 111, with both ends of the left and right sides of the partitions 112 alternately connected to each other to form a cascade channel assembly 110 having a zigzag-shaped internal channel.

[0041] According to one embodiment, the plurality of partitions 112 of the cascade flow path assembly 110 are formed with communication holes 112a alternately at both ends of the left and right sides, so that the cascade flow path assembly 110 has a zigzag-shaped internal flow path as a whole.

[0042] Each of the communication holes 112a is provided with a drain guide plate 115, one end of which is connected to the partition plate 112 and the other end of which is bent downward through the communication hole 112a and has a free end shape.

[0043] Further, an air intake unit 120 is provided which is connected to one side of the lower portion of the cascade flow path assembly 110 to draw in ambient air and guide the drawn air to flow upward along the internal flow path of the cascade flow path assembly 110.

[0044] According to one embodiment, the air intake unit 120 is provided with at least one of a thermo-hygrometer 182 for measuring the temperature, humidity, or carbon dioxide concentration of the air taken in from the surroundings, or a carbon dioxide concentration meter 183, and further provided with a preheater 181 for preheating the taken in air to a temperature suitable for reaction with the basic-alkali mixed solution.

[0045] The preheater 181 serves to preheat the intake air for the carbon dioxide capture reaction described below.

[0046] Furthermore, a mixture storage unit 130 is provided at the bottom of the cascade flow path assembly 110, and stores a basic alkaline mixture of specific components that undergoes a chemical reaction upon contact with air to capture carbon dioxide in the air. When air is drawn into the air intake unit 120, the basic alkaline mixture is supplied to the top of the cascade flow path assembly 110, and the basic alkaline mixture flows downward due to its own weight along the internal flow path of the cascade flow path assembly 110, and is brought into surface contact with the air.

[0047] Meanwhile, the basic-alkali mixed solution flows downward from the mixed solution storage unit 130 along the internal flow path of the cascade flow path assembly 110, and then continues to circulate back to the mixed solution storage unit 130, capturing carbon dioxide in the air.

[0048] 4, the basic alkali mixture flows downward along the upper surface of the drain guide plate 115 provided in the communication hole 112a of the partition plate 112. At this time, air is moving upward below the drain guide plate 115, so the basic alkali mixture flows downward like a curtain and continuously comes into contact with the air. That is, during this process, the basic alkali mixture comes into contact with the air in a cutting direction, causing collisions with the air and generating vortexes, which accelerates the carbon dioxide capture reaction.

[0049] The partitions 112 may be formed by stacking multiple rectangular stainless steel plates. For example, 18 partitions may be stacked at regular intervals. Air and the basic-alkali mixture flow upward or downward along the internal flow path of the cascade flow path assembly 110 in a zigzag pattern from one end of each partition 112 to the communication hole 112a at the other end.

[0050] In this process, air flowing in through the air intake 120 passes through the cascade flow path assembly 110 and is continuously in surface or vortex contact with the basic-alkali mixture until it exits the air outlet 140, whereby carbon dioxide in the air reacts with the basic-alkali mixture and is captured. According to one embodiment, the device can remove more than 90% of carbon dioxide in the air.

[0051] The height of the basic alkali mixture flowing to each partition 112 may be set to 1 mm to 10 mm. More specifically, it may be set to 2 mm to 8 mm, 4 mm to 8 mm, 6 mm to 10 mm, or 2 mm to 6 mm. The height of the basic alkali mixture flowing to each partition 112 may be changed to a predetermined value depending on the flow rate and flow velocity of the air flowing in from the air inlet 120 so that carbon dioxide can be maximized.

[0052] In addition, the plurality of partition plates 112 may be formed in a pattern. For example, they may be protruding or recessed in a triangular pyramid or semicircular shape, and may be patterned in various shapes, such as a sinusoidal wave shape, a ridge and valley shape, etc. The plurality of partition plates 112 having such a pattern may have an increased contact area with air, thereby capturing more carbon dioxide.

[0053] Thereafter, the air from which carbon dioxide has been removed as described above is finally discharged to the outside through the air discharge part 140.

[0054] In addition, a heater (not shown) may be further provided in the mixed solution storage unit 130. The heater functions to heat the mixed solution so as to prevent the formation of precipitates in the mixed solution, since sodium carbonate and the like may precipitate if the mixed solution stored in the mixed solution storage unit 130 is cooled below a certain temperature.

[0055] According to one embodiment, the mixed solution storage unit 130 is further provided with a circulation pump 150, and the circulation pump 150 supplies the basic-alkali mixed solution stored in the mixed solution storage unit 130 to the upper part of the cascade flow path assembly 110 via a mixed solution supply pipe 151.

[0056] The mixture supply pipe 151 is connected to a plurality of mixture inlets 113 formed at the upper end of a cascade channel assembly 110, which will be described later. For example, three or more mixture inlets 113 may be provided to allow the mixture to be uniformly supplied according to the width of the partition (see FIGS. 3 and 4).

[0057] According to an embodiment, a level indicator (not shown) is provided inside the mixed solution reservoir 130, so that the level of the solution can be detected.

[0058] Furthermore, an air outlet 140 is provided at the top of the cascade flow path assembly 110 to discharge the remaining air from which carbon dioxide has been removed via the internal flow path to the surroundings.

[0059] According to one embodiment, the air discharge unit 140 is provided with at least one of a flow meter 185, a temperature / hygrometer 182, or a carbon dioxide concentration meter 183 for measuring the flow rate, temperature, humidity, or carbon dioxide concentration value of the air from which carbon dioxide has been removed.

[0060] According to an embodiment, an air intake fan 170 is further installed in a part of the flow path of the air discharge part 140. The air intake fan 170 may be installed in the air intake part 120 as well as the air discharge part 140.

[0061] In addition, the lowest partition 112 of the cascade flow path assembly 110 and the open upper part of the mixed liquid storage unit 130 are connected to each other, and the air intake unit 120 is connected to the space between the lowest partition 112 of the cascade flow path assembly 110 and the mixed liquid storage unit 130, so that air taken in from the outside comes into contact with the basic-alkali mixed liquid stored in the mixed liquid storage unit 130 and is then guided to flow upward along the internal flow path through the communication hole 112a of the lowest partition 112 of the cascade flow path assembly 110.

[0062] In addition, a replenishment water reservoir 160 is further provided on one side of the mixed solution reservoir 130 to replenish water evaporated from the basic-alkali mixed solution.

[0063] When the water level in the mixed solution reservoir 130 decreases due to natural evaporation of water from the basic-alkali mixed solution, the mixed solution reservoir 130 is replenished with water from the replenisher water reservoir 160 .

[0064] At this time, the water level is sensed using a level indicator provided in the mixed liquid reservoir 130, and water is replenished from the replenishment water reservoir 160 to the mixed liquid reservoir 130 according to a predetermined condition.

[0065] In addition, the carbon dioxide concentration value before carbon dioxide capture in the air inhaled through the air inlet 120 and the carbon dioxide concentration value after carbon dioxide capture in the remaining air discharged through the air outlet after carbon dioxide has been removed by reaction with the basic-alkali mixed solution stored in the mixed solution storage unit are measured and compared, and then the amount of water supplied to the mixed solution storage unit 130 is adjusted.

[0066] The mixed solution reservoir 130 may maintain the ratio of the basic alkaline solution to the water supplied from the replenisher water reservoir 160 at 1:1 to 1:5. For example, the ratio of the basic alkaline solution to the water may be maintained at 1:1 to 1:4, 1:1 to 1:3, 1:1 to 1:2, 1:2 to 1:5, 1:2 to 1:3, or 1:3 to 1:5.

[0067] The ratio of the basic alkaline solution to water can increase the efficiency of capturing carbon dioxide from the air as the ratio of the basic alkaline solution increases, but the ratio of water can be adjusted in consideration of cost.

[0068] The basic-alkali mixture is characterized by comprising: one or more oxides selected from the group consisting of SiO2, Al2O3, Fe2O3, TiO2, MgO, MnO, CaO, Na2O, KO, and PO3; one or more metals selected from the group consisting of Li, Cr, Co, Ni, Cu, Zn, Ga, Sr, Cd, and Pb; a crystallized synthetic zeolite made from an alumina-based raw material, a silica-based raw material, and sodium hydroxide; and one or more liquid compositions selected from the group consisting of sodium tetraborate (Na2B4O7·10HO), sodium hydroxide (NaOH), sodium silicate (Na2SiO3), potassium hydroxide (KOH), and hydrogen peroxide (HO2).

[0069] The average pH of the basic-alkaline mixture may be equal to or greater than pH 12. For example, the pH may be between pH 12 and pH 13.5, pH 13, pH 12, pH 12.1, pH 12.2, or pH 12.3. The pH of the basic-alkaline mixture may be measured by the pH meter 184 in the mixture reservoir 130, as described above.

[0070] When the pH of the basic-alkali mixed solution in the mixed solution storage unit 130 becomes less than 10.5, carbon dioxide can no longer be captured, so the carbon dioxide reactant and waste solution are discharged to the outside through an outlet 131 provided at the bottom of the mixed solution storage unit 130, and a new basic-alkali mixed solution is supplied through the outlet 131.

[0071] For this purpose, a pump 200 is further provided on one side of the mixed liquid storage unit 130 .

[0072] The pump 200 discharges the carbon dioxide reactant and waste solution to the outside through the outlet 131, and supplies a new basic alkaline mixed solution produced by mixing the basic alkaline solution and water through the outlet 131.

[0073] At this time, the mixed solution storage unit 130 is provided with a pH meter 184, which monitors whether the pH of the basic-alkali mixed solution stored in the mixed solution storage unit 130 is maintained at an appropriate pH of 12 to 13.5.

[0074] Meanwhile, when the level of the basic-alkali mixed solution in the mixed solution storage unit 130 drops below 90%, the basic-alkali mixed solution is supplied from the pump 200 to the mixed solution storage unit 130 through a valve (not shown), and when the level of the basic-alkali mixed solution reaches 100%, the supply is stopped.

[0075] Meanwhile, although not shown in the drawing, the mixed solution storage unit 130 may be further connected to a separator (not shown) that collects reactants including carbon dioxide captured in the basic-alkali mixed solution and separates the carbon dioxide reactant and waste solution from the reactants, and a carbon resource storage (not shown) that stores the separated carbon dioxide reactant for recycling.

[0076] Thus, the carbon dioxide reactant and the waste solution discharged to the outside through the outlet 131 of the mixed solution storage unit 130 can be sent to a separator (not shown) and then separated into the carbon dioxide reactant and the waste solution. For example, the separator (not shown) may separate the carbon dioxide reactant and the waste solution using a centrifuge.

[0077] The carbon dioxide reactant separated by the separator may be sent to a carbon resource storage (not shown) for storage and then recycled for other uses. For example, the carbon dioxide reactant may include sodium carbonate (NaCO) or sodium bicarbonate (NaHCO).

[0078] The cascade-type artificial reforestation device 100 of the present invention described above can be easily installed and moved on land, and when installed on land, it is easy to secure a place to store the carbon dioxide reactant, so the carbon dioxide reactant can be separated and stored in a carbon resource storage facility (not shown) to be recycled into other useful substances.

[0079] The carbon dioxide reactant may be produced by reacting a basic alkali mixture with carbon dioxide as shown in the following <Reaction Scheme 1>.

[0080] <Reaction Scheme 1>

[0081] 2NaOH+CO2 → Na2CO3+H2O

[0082] Na2CO3+H2O+CO2→2NaHCO3

[0083] The waste solution obtained by removing the carbon dioxide reactant from the reactants is transferred to a wastewater treatment tank (not shown) and disposed of. For example, the waste solution may contain illite minerals and water that were contained in the basic-alkali mixed solution after it has finished functioning as a catalyst.

[0084] In addition, after the air supplied through the air intake unit 120 and the basic-alkali mixed solution stored in the mixed solution storage unit 130 are subjected to a surface contact reaction to capture carbon dioxide, the remaining air from which the carbon dioxide has been removed is discharged through the air discharge unit 140. For example, the remaining air discharged through the air discharge unit 140 may include air from which the carbon dioxide has been removed and a small amount of carbon dioxide that has not been captured. Here, the remaining air may be The carbon dioxide content is less than 10% of the carbon dioxide content of the air flowing in from the air intake section 120. It can mean air.

[0085] In addition, insect screens may be further installed on the air inlet 121 and the air outlet 141 (see FIGS. 2b and 2c).

[0086] Meanwhile, the cascade type artificial reforestation device of the present invention may include an electrical component unit 190 .

[0087] The electrical equipment unit 190 monitors and manages data received from thermometers / hygrometers, flow meters, pH meters, etc., which are measured during all stages of the artificial reforestation device, and controls the opening and closing of various valves of the circulation pump 150, intake fan 170, mixed liquid storage unit 130, and replenishment water storage unit 160 based on the data.

[0088] That is, the electrical equipment unit 190 can control the flow rates and flow speeds of the air and basic alkaline mixed solution based on data measured by the various sensors.

[0089] In addition, when the user inputs the carbon dioxide capture date, time, measurement interval, measurement start time for measuring the carbon dioxide concentration value, measurement end time for ending the measurement of the carbon dioxide concentration value, measurement period, and atmospheric pressure via the electrical equipment unit 190, the electrical equipment unit 190 can control the operation of each part of the cascade-type artificial reforestation device of the present invention based on the input values.

[0090] The electrical equipment unit 190 can store various data measured by the sensors in a database. Specifically, the data can include at least the amount of CO2 emitted before carbon dioxide capture, the amount of CO2 emitted after carbon dioxide capture, the amount of CO2 captured in a predetermined period, the amount of carbon dioxide captured per hour, and the predicted amount of CO2 captured in a certain period in the future.

[0091] In addition, the electrical equipment unit 190 can remotely transmit the stored itemized data to a server or terminal desired by the user in real time or at regular intervals. As a result, a local government or manager in an area where the cascade-type artificial reforestation device of the present invention is installed can constantly check the change in the amount of carbon dioxide capture due to the operation of the artificial reforestation device and the predicted amount of carbon dioxide capture in the future remotely via a communication device including a server, smartphone, or computer terminal.

[0092] Although the present invention has been described above with reference to the accompanying drawings, those skilled in the art will understand that the present invention can be embodied in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments should be understood to be illustrative in all respects and not limiting. The scope of this specification is defined by the claims set forth below, rather than the above detailed description, and all changes and modifications derived from the meaning and scope of the claims and their equivalents should be construed as being within the scope of this specification.

[0093] Meanwhile, the present specification and drawings disclose preferred embodiments of the present specification, and although specific terms are used, they are used in a general sense to easily explain the technical content of the specification and to aid in understanding the invention, and are not intended to limit the scope of the present invention. It will be obvious to those skilled in the art to which the present invention pertains that, in addition to the embodiments disclosed herein, other modifications based on the technical ideas of the present specification can be implemented. [Industrial Applicability]

[0094] The present invention can provide an artificial reforestation device that can efficiently reduce carbon dioxide emitted into the air and recycle it into other useful materials, as well as continue to supply artificially purified, clean air.

[0095] Furthermore, according to the present invention, local governments and managers with jurisdiction over the area can easily check the amount of change in carbon dioxide concentration before and after carbon dioxide capture, allowing them to make appropriate use of this information or to take appropriate measures depending on the change in carbon dioxide concentration.
