Description

Technical Field

[0001] This invention relates to the field of environmental protection technology, and more specifically, to a carbon dioxide absorption device. Background Technology

[0002] Currently, the kitchen waste gas produced by burning natural gas in residential buildings carries a large amount of carbon dioxide, which is released into the air and exacerbates air pollution.

[0003] Household appliances using related technologies, such as range hoods, can only separate grease from kitchen waste fumes, but cannot absorb the carbon dioxide within them. This results in high carbon dioxide emissions, exacerbating air pollution. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention provide a carbon dioxide absorption device that has the advantages of reducing carbon dioxide emissions and reducing air pollution.

[0005] According to an embodiment of the present invention, a carbon dioxide absorption device includes a chamber, a carbon dioxide separation membrane, a piston, and a plug. The carbon dioxide separation membrane is disposed in the chamber and divides the chamber into a first chamber and a second chamber. The piston is sealed in the second chamber and is slidable along its alignment direction with the carbon dioxide separation membrane. A variable-volume chamber is formed between the piston and the carbon dioxide separation membrane. The piston or the chamber has an exhaust gas inlet communicating with the variable-volume chamber and the outside. The chamber has an exhaust gas outlet communicating with the variable-volume chamber and the outside. The plug is connected to the piston and includes a solid section and a hollow section arranged in the alignment direction of the piston and the carbon dioxide separation membrane. The piston has a first sliding state and a second sliding state. In the first sliding state, the piston is positioned away from the carbon dioxide separation membrane, and the solid section cooperates with the exhaust gas outlet to block the exhaust gas outlet. In the second sliding state, the piston is positioned close to the carbon dioxide separation membrane, and the hollow section cooperates with the exhaust gas outlet to form a vent for the flow of kitchen waste gas.

[0006] According to an embodiment of the carbon dioxide absorption device of the present invention, kitchen waste gas enters the variable volume chamber through the waste inlet. Then, the piston slides towards the carbon dioxide separation membrane, gradually reducing the volume of the variable volume chamber, allowing carbon dioxide in the kitchen waste gas to pass through the carbon dioxide separation membrane and enter the first chamber. At this time, the piston is in a first sliding state, with the solid section blocking the waste gas outlet, thereby preventing the kitchen waste gas and its carbon dioxide from being discharged from the chamber through the waste gas outlet. After most of the carbon dioxide in the kitchen waste gas has entered the first chamber, the piston changes from the first sliding state to a second sliding state, with the hollow section and the waste gas outlet cooperating to form a ventilation channel. Then, the kitchen waste gas, having released carbon dioxide, is discharged from the chamber through the ventilation channel. Thus, the carbon dioxide absorption device in this embodiment achieves the effect of separating and collecting carbon dioxide from kitchen waste gas, reducing the amount of carbon dioxide emitted into the air, thereby reducing air pollution.

The filter screen is disposed in the second chamber and located on the side of the turbine away from the carbon dioxide separation membrane. The filter screen is adapted to filter liquid water and oil droplets in the kitchen waste gas. The impeller is installed in the second chamber and located between the turbine and the filter screen.

[0010] In some embodiments, there are multiple impellers, which are spaced apart in a first direction perpendicular to the arrangement direction of the piston and the carbon dioxide separation membrane.

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] The following is combined Figures 1-3 A carbon dioxide absorption apparatus according to an embodiment of the present invention is described.

[0022] like Figure 1 As shown, the carbon dioxide absorption device according to the present invention includes a chamber 1, a carbon dioxide separation membrane 2, a piston 3, and a plug 4. The carbon dioxide separation membrane 2 is disposed in the chamber 1 and divides the chamber 1 into a first chamber 11 and a second chamber 12. The piston 3 is sealed in the second chamber 12 and can slide along the alignment direction with the carbon dioxide separation membrane 2. A variable volume chamber 13 is formed between the piston 3 and the carbon dioxide separation membrane 2. The piston 3 or the chamber 1 is provided with an exhaust gas inlet that connects the variable volume chamber 13 to the outside. The chamber 1 is provided with an exhaust gas outlet 14 that connects the variable volume chamber 13 to the outside. The plug 4 is connected to the piston 3. The plug 4 includes a solid section 41 and a hollow section 42 arranged in the direction of the piston 3 and the carbon dioxide separation membrane 2. The piston 3 has a first sliding state and a second sliding state. In the first sliding state, the piston 3 is located away from the carbon dioxide separation membrane 2, and the solid section 41 cooperates with the exhaust gas outlet 14 and blocks the exhaust gas outlet 14. In the second sliding state, the piston 3 is located close to the carbon dioxide separation membrane 2, and the hollow section 42 cooperates with the exhaust gas outlet 14 and forms a venting channel for the flow of kitchen waste gas.

[0023] According to the carbon dioxide absorption device of the present invention, kitchen waste gas enters the variable volume chamber 13 through the waste inlet. Then, the piston 3 slides towards the carbon dioxide separation membrane 2, and the volume of the variable volume chamber 13 gradually decreases, allowing carbon dioxide in the kitchen waste gas to pass through the carbon dioxide separation membrane 2 and enter the first chamber 11. At this time, the piston 3 is in the first sliding state, and the solid section 41 blocks the waste gas outlet 14, thereby preventing the kitchen waste gas and the carbon dioxide therein from being discharged from the chamber 1 through the waste gas outlet 14.

[0024] After most of the carbon dioxide in the kitchen waste gas has entered the first chamber 11, the piston 3 changes from the first sliding state to the second sliding state, and the hollow section 42 and the exhaust outlet 14 cooperate to form a ventilation channel. Then, the kitchen waste gas, having released carbon dioxide, is discharged from the chamber 1 through the ventilation channel. Thus, the carbon dioxide absorption device in this embodiment achieves the effect of separating and collecting carbon dioxide from kitchen waste gas, reducing the amount of carbon dioxide emitted into the air, thereby reducing air pollution.

[0025] Understandably, the carbon dioxide separation membrane 2 is used to screen carbon dioxide gas in kitchen waste gas and isolate other gases in kitchen waste gas. In addition, the carbon dioxide separation membrane 2 is also used to block the backflow of carbon dioxide from the first chamber 11 to the variable volume chamber 13.

[0026] It should be noted that the initial volume of the variable volume cavity 13 can be referred to as the first volume, and the volume of the variable volume cavity 13 when the hollow section 42 and the exhaust outlet 14 are initially matched can be referred to as the second volume. The second volume is approximately three-quarters of the first volume.

[0027] It should be noted that, compared with traditional range hoods, the carbon dioxide absorption device in this embodiment reduces the carbon dioxide content in the kitchen waste gas discharged from chamber 1 by at least 80%.

[0028] In some embodiments, such as Figure 1 As shown, it also includes a turbine 121, which is placed in the second chamber 12 and located on the side of the piston 3 away from the carbon dioxide separation membrane 2. The exhaust gas inlet is located on the piston 3. The exhaust gas outlet of the turbine 121 is connected to the exhaust gas inlet. The intake port of the turbine 121 is used to draw in kitchen waste exhaust gas.

[0029] Therefore, when the piston 3 slides, the turbine 121 continuously supplies kitchen waste gas into the variable volume chamber 13, thereby ensuring that the gas pressure in the variable volume chamber 13 is at a high level, which facilitates the entry of carbon dioxide in the kitchen waste gas through the carbon dioxide separation membrane 2 into the first chamber 11. In addition, when the piston 3 slides, the activated turbine 121 prevents the high-pressure gas in the variable volume chamber 13 from flowing back to the turbine 121 through the waste gas inlet.

[0030] In some embodiments, the carbon dioxide absorption device further includes a telescopic pipe, the turbine 121 is connected to the chamber 1, and the outlet of the turbine 121 is connected to the exhaust gas inlet through the telescopic pipe.

[0031] When piston 3 slides, it causes the exhaust gas inlet to slide, which in turn causes the telescopic tube to extend or retract. Thus, when piston 3 and turbine 121 slide relative to each other, the telescopic tube achieves position compensation between them.

[0032] In some embodiments, such as Figure 1 and Figure 2As shown, the carbon dioxide absorption device also includes a filter screen 122 and an impeller 123. The filter screen 122 is disposed in the second chamber 12 and located on the side of the turbine 121 opposite to the carbon dioxide separation membrane 2. The filter screen 122 is suitable for filtering liquid water and oil droplets in kitchen waste gas. The impeller 123 is installed in the second chamber 12 and located between the turbine 121 and the filter screen 122.

[0033] As a result, the impeller 123 generates negative pressure when rotating, allowing kitchen waste gas outside the chamber 1 to enter the impeller 123 through the filter screen 122. This allows the filter screen 122 to filter liquid water and oil droplets from the kitchen waste gas. Furthermore, the water vapor and oil in the kitchen waste gas entering the impeller 123 are cooled into a liquid state by the high-speed rotation of the impeller 123 and are thrown against the inner wall of the chamber 1 by the centrifugal force of the impeller 123. They then flow along the inner wall of the chamber 1 to the filter screen 122, thus achieving secondary collection of liquid water and oil droplets from the kitchen waste gas by the filter screen 122.

[0034] Understandably, after passing through impeller 123, the liquid water and oil droplets in the kitchen waste gas are removed. Then, under the action of turbine 121, the kitchen waste gas enters variable volume chamber 13.

[0035] In some embodiments, such as Figure 1 and Figure 2 As shown, there are multiple impellers 123, which are spaced apart in a first direction, which is perpendicular to the arrangement direction of the piston 3 and the carbon dioxide separation membrane 2.

[0036] As a result, the multiple impellers 123 increase the distribution area of ​​the impellers 123 in the second chamber 12, improve the absorption effect and efficiency of the impellers 123 for kitchen waste gas, and thus increase the filtration efficiency of the filter screen 122.

[0037] Specifically, there are two impellers 123.

[0038] In some embodiments, such as Figures 1-3As shown, the piston 3 and the carbon dioxide separation membrane 2 are arranged in the same direction as the height of the chamber 1, and the first chamber 11 is located above the second chamber 12. The carbon dioxide absorption device also includes inclined guide plates 124 and oil collection cups 126. There are multiple guide plates 124, all located below the filter screen 122. The multiple guide plates 124 are evenly distributed around the circumference of the chamber 1. Each guide plate 124 has a first end adjacent to the center line of the chamber 1 and a second end away from the center line of the chamber 1. The first end of the guide plate 124 is located below the second end, and the second end of the guide plate 124 is connected to the peripheral wall of the chamber 1 that forms the second chamber 12. Any two adjacent guide plates 124 are connected. The surface of the guide plate 124 is provided with multiple evenly distributed through holes for the flow of kitchen waste gas. The first ends of the multiple guide plates 124 enclose each other to form an oil outlet 125, and the oil collection cup 126 is detachably connected to the oil outlet 125.

[0039] As a result, the liquid water and oil droplets thrown onto the inner wall of the chamber 1 by the impeller 123 flow to the filter screen 122 under their own weight and mix with the liquid water and oil droplets already present in the filter screen 122. Then, the liquid water and oil droplets flow to the guide plate 124 due to gravity and converge on the inclined guide plate 124 to the oil outlet 125. Subsequently, the liquid water and oil droplets fall into the oil collection cup 126.

[0040] The oil collecting cup 126 is used to collect liquid water and oil droplets that converge due to the guide plate 124. When the oil collecting cup 126 is full of liquid water and oil droplets, the oil collecting cup 126 can be removed, the liquid water and oil droplets in the oil collecting cup 126 can be poured out, and the oil collecting cup 126 can be reinstalled at the oil outlet 125. Alternatively, a new oil collecting cup 126 can be directly replaced.

[0041] Specifically, there are four deflector plates 124.

[0042] Specifically, the four guide vanes 124 are connected end to end in the circumferential direction of the chamber body 1.

[0043] Specifically, the oil collecting cup 126 and the oil outlet 125 can be connected by snap-fit ​​or thread, etc. The connection method between the two is a conventional technology in this field and will not be described in detail here.

[0044] Understandably, the impeller 123 is located above the filter screen 122.

[0045] For ease of understanding, Figure 1 Arrow A in the diagram indicates the height direction of compartment 1.

[0046] In some embodiments, such as Figure 2 As shown, the carbon dioxide absorption device also includes a fume hood 6. The bottom end of the chamber 1 has an opening that connects the second chamber 12 to the outside. The fume hood 6 is connected to the bottom end of the chamber 1 and covers the opening.

[0047] Therefore, the fume hood 6 has a diversion function for kitchen waste gas, making it easier for the kitchen waste gas to enter the second chamber 12 through the opening.

[0048] In some embodiments, such as Figure 1 As shown, the carbon dioxide absorption device also includes a compression system 111, a pipeline 112, and a storage tank 5. The compression system 111 is installed inside the first chamber 11, and its inlet is used to draw in carbon dioxide from the first chamber 11. The first end of the pipeline 112 is connected to the outlet of the compression system 111. The storage tank 5 is located outside the chamber 1, and its second end is connected to the pipeline 112.

[0049] Thus, the compression system 111 is used to pressurize the carbon dioxide in the first chamber 11 to the storage tank 5 through the pipe 112, thereby achieving the sealing and storage of carbon dioxide.

[0050] In some embodiments, such as Figure 1 As shown, the shape of the plug 4 includes any one of strip, rod, plate and block, and the solid section 41 is located above the hollow section 42. The hollow section 42 includes a long groove or hollow section formed in the plug 4.

[0051] This facilitates the solid section 41 to block the exhaust gas outlet 14, and facilitates the hollow section 42 to cooperate with the exhaust gas outlet 14 to form a ventilation channel.

[0052] In addition, the hollow section in this embodiment ensures both the formation of the ventilation channel and the structural strength of the plug 4.

[0053] In some embodiments, such as Figure 2 As shown, the carbon dioxide absorption device also includes a drive unit and a switch 7. Either the plug 4 or the piston 3 is driven by the drive unit. The switch 7 is located on the peripheral wall of the chamber 1 and is electrically connected to the drive unit.

[0054] Thus, the drive device is used to control the sliding of the piston 3 and the plug 4 in the second chamber 12 along the height direction of the chamber body 1, and the switch 7 is used to open, close and adjust the drive device.

[0055] Specifically, the driving device can be an electric actuator, a pneumatic cylinder, or a hydraulic cylinder, etc.

[0056] It should be noted that switch 7 is located between filter 122 and fume hood 6.

[0057] In summary, the carbon dioxide absorption device of the present invention has the following beneficial effects:

[0058] (1) It avoids the direct emission of carbon dioxide from kitchen waste gas into the air environment, thereby reducing air pollution and achieving the effect of environmental protection.

[0059] (2) The carbon dioxide collected in storage tank 5 can be sold as a product.
