Description

Technical Field

[0001] This application relates to the technical field of waste gas recovery, and in particular to a collection and recovery system that uses a steam compressor to separate carbon dioxide. Background Technology

[0002] With societal development, human activities such as industry, energy production, transportation, agriculture, and household activities generate a significant amount of waste gas, containing large quantities of carbon dioxide. Carbon dioxide is a major greenhouse gas, and its direct release into the environment can easily increase atmospheric greenhouse gas concentrations, exacerbating the greenhouse effect and contributing to global warming and other climate change phenomena. Furthermore, excessive carbon dioxide emissions also negatively impact air quality, water resources, and ecosystems.

[0003] Therefore, it is necessary to design a carbon dioxide collection and recovery system that can separate carbon dioxide from waste gas. Summary of the Invention

[0004] In order to separate and recover carbon dioxide from waste gas, this application provides a collection and recovery system that uses a steam compressor to separate carbon dioxide.

[0005] This application provides a collection and recovery system for separating carbon dioxide using a steam compressor, employing the following technical solution: A collection and recovery system for separating carbon dioxide using a steam compressor includes a frame and a steam compressor mounted on the frame. An air inlet device is provided on the frame to guide waste gas into the steam compressor, which compresses the waste gas to a pressure greater than 7.38 MPa. A storage chamber is provided on the frame, and the interior of the storage chamber is hollow. An output pipe is provided on the frame, with its two ends connected to the steam compressor and the interior of the storage chamber, respectively. Waste gas with a pressure greater than 7.38 MPa enters the storage chamber through the output pipe. A cooling device is provided inside the storage chamber to reduce the temperature to below 31.3°C. An outlet pipe is provided on the storage chamber, communicating with the interior of the storage chamber.

[0006] By adopting the above technical solution, the intake device is activated to absorb the waste gas and input the absorbed waste gas into the steam compressor. The steam compressor compresses the waste gas to a pressure greater than 7.38 MPa, and then the compressed waste gas is passed into the output pipe, which in turn passes into the storage chamber. The cooling device in the storage chamber is activated to cool the storage chamber, reducing the temperature to below 31.3°C. At this point, the carbon dioxide in the waste gas liquefies and falls to the bottom of the storage chamber, which collects the liquefied carbon dioxide. Excess waste gas is discharged from the storage chamber through the exhaust pipe, thus completing the separation and collection of carbon dioxide in the waste gas, reducing carbon emissions from the waste gas, saving energy, and protecting the environment.

[0007] Optionally, the air intake device includes: A suction fan, which is mounted on a frame; An air intake pipe is mounted on the frame, with one end connected to a suction fan and the other end connected to a steam compressor. An air guide shroud is mounted on the suction fan.

[0008] By adopting the above technical solution, the suction fan starts to draw in the exhaust gas, and the air guide hood guides the exhaust gas so that the exhaust gas can be concentrated into the air inlet pipe and lead to the steam compressor, thereby completing the work of guiding the exhaust gas into the steam compressor.

[0009] Optionally, the steam compressor includes a compression chamber and a power chamber. The compression chamber includes a first housing, which is mounted on a frame and connected to both an inlet pipe and an outlet pipe. A rotating shaft is rotatably mounted on the first housing, and multiple impellers are mounted on the rotating shaft. Diffuser guide vanes are evenly distributed on the impellers. The power chamber is used to drive the impellers to rotate.

[0010] By adopting the above technical solution, after the exhaust gas enters the first housing through the intake pipe, the power chamber starts to work and drives the shaft to rotate. The rotation of the shaft drives the impeller to rotate, and the rotation of the impeller drives the diffuser guide vane to rotate. The rotation of the diffuser guide vane pressurizes the exhaust gas passing through the impeller, thereby completing the pressurization of the exhaust gas.

[0011] Optionally, the power chamber includes: The second housing is mounted on the frame, and an air inlet and an air outlet are respectively opened at both ends of the second housing; The first driving air tube has one end disposed on the air inlet pipe and connected to the inside of the air inlet pipe, and the other end of the first driving air tube is connected to the air inlet. The second driving air pipe has one end disposed on the second housing and connected to the air outlet, and the other end of the second driving air pipe is connected to the inside of the air inlet pipe. A pneumatic worm gear, which is rotatably disposed within a second housing; A drive worm gear is mounted on a rotating shaft; A drive worm gear, one end of which is located inside the second housing and meshes with a pneumatic worm wheel, and the other end of which extends into the first housing and meshes with a drive worm wheel.

[0012] By adopting the above technical solution, after the exhaust fan draws the exhaust gas into the intake pipe, a portion of the exhaust gas entering the intake pipe enters the second housing through the first drive air pipe and enters from the air inlet of the second housing and exits from the air outlet. The pneumatic worm gear located in the second housing rotates under the action of the flowing exhaust gas. The rotation of the pneumatic worm gear drives the drive worm to rotate, the drive worm to rotate, the drive worm gear to rotate, the drive worm gear to rotate, the shaft to rotate, and the shaft to rotate, thus realizing the operation of the impeller located in the compression chamber rotating at the same time as the exhaust gas is introduced into the compression chamber through the intake pipe. Furthermore, by setting up the second drive air pipe, the exhaust gas driving the worm gear to rotate can be guided back into the intake pipe, thereby making full use of the kinetic energy of the exhaust gas, saving energy and protecting the environment, and achieving high working efficiency.

[0013] Optionally, the cooling device includes: A heat exchanger, wherein the heat exchanger is disposed within the storage chamber; A condensation drip plate is disposed inside the storage chamber and below the heat exchanger. The temperature between the heat exchanger and the condensation drip plate is less than 31.3°C. The condensation drip plate is inclined. The height of the end of the condensation drip plate away from the output pipe is lower than the height of the end of the condensation drip plate connected to the storage chamber. A gap is left between the lower end of the condensation drip plate and the inner wall of the storage chamber for liquid carbon dioxide to flow down.

[0014] By adopting the above technical solution, the heat exchanger is activated to cool the temperature inside the storage chamber. The heat exchanger lowers the temperature inside the storage chamber to below 31.3℃. When the exhaust gas enters the storage chamber, because the exhaust gas pressure is greater than 7.38 MPa and the temperature is lower than 31.3℃, the carbon dioxide in the exhaust gas liquefies and drips onto the condenser plate. The liquefied carbon dioxide flows down the inclined direction of the condenser plate from the condenser plate to the bottom of the storage chamber for collection. This achieves the cooling effect of the storage chamber and completes the separation and collection of carbon dioxide.

[0015] Optionally, the heat exchanger is provided with a refrigerant pipe and a heat transfer pipe, and the condenser drip plate has a cavity inside. The condenser drip plate is provided with a first connecting pipe and a second connecting pipe that communicate with the cavity. The end of the first connecting pipe away from the condenser drip plate is connected to the refrigerant pipe and communicates with the interior of the refrigerant pipe. The end of the second connecting pipe away from the condenser drip plate is connected to the heat transfer pipe and communicates with the interior of the heat transfer pipe.

[0016] By adopting the above technical solution, the condensing drip plate is connected to the refrigerant pipe and the heat transfer pipe on the heat exchanger using the first connecting pipe and the second connecting pipe. This allows the refrigerant in the refrigerant pipe to enter the condensing drip plate and reduce the surface temperature of the condensing drip plate, making it easier for carbon dioxide in the exhaust gas to liquefy on the surface of the condensing drip plate. Furthermore, the condensing drip plate and the heat exchanger form a whole to cool the storage chamber, thus improving the cooling effect of the storage chamber on the exhaust gas.

[0017] Optionally, one end of the air outlet pipe is disposed on the storage chamber and communicates with the interior of the storage chamber, and the other end of the air outlet pipe is connected to the first driving air pipe and communicates with the interior of the first driving air pipe.

[0018] By adopting the above technical solution, the waste gas entering the storage chamber is guided back into the first drive gas pipe after being discharged from the gas outlet pipe to drive the starting gear. In this way, the kinetic energy of the gas that still has a certain pressure after condensation is utilized, which saves energy, protects the environment, and reduces energy consumption.

[0019] Optionally, the storage chamber is provided with a filter baffle, which is divided into a first plate and a second plate. The first plate is disposed on the inner wall of the storage chamber and is in a horizontal state. The first plate is located above the heat exchanger. The second plate is disposed on the first plate and is in a vertical state. The second plate is located between the heat exchanger and the output pipe.

[0020] By adopting the above technical solution, filter baffles are installed above and on the side of the heat exchanger. The filter baffles filter the exhaust gas and filter out the particulate matter in the exhaust gas, thereby reducing the probability of particulate matter in the exhaust gas adhering to the heat exchanger and ensuring the heat exchange effect of the heat exchanger.

[0021] Optionally, a temperature sensor is installed on the storage compartment, and solenoid valves are installed on both the refrigerant pipe and the heat pipe. A controller is installed on the storage compartment, and the controller is electrically connected to both the temperature sensor and the solenoid valves.

[0022] By adopting the above technical solution, the temperature sensor senses the temperature inside the storage chamber and transmits the sensed temperature signal to the controller. The controller converts the temperature signal received from the temperature sensor into an electrical signal and transmits it to the solenoid valve to control the opening and closing of the solenoid valve. When the temperature sensor senses that the temperature inside the storage chamber is higher than 31.3℃, the controller controls the solenoid valve to increase the opening degree of the refrigerant pipe, thereby keeping the temperature inside the storage chamber below 31.3℃ and ensuring the liquefaction effect of carbon dioxide in the storage chamber.

[0023] Optionally, the storage chamber is provided with a liquid outlet pipe at the bottom, the liquid outlet pipe is connected to the inside of the storage chamber, the liquid outlet pipe is provided with a switch valve, and the storage chamber is provided with an observation window.

[0024] By adopting the above technical solution, staff can observe the amount of liquid carbon dioxide collected inside the storage chamber through the observation window, and by opening the switch valve, the collected carbon dioxide can be discharged from the liquid outlet pipe for subsequent collection and processing, thus completing the work of exporting carbon dioxide from the storage chamber for subsequent utilization.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The exhaust gas is absorbed by the intake device and fed into the steam compressor. The steam compressor compresses the exhaust gas to a pressure greater than 7.38 MPa. The compressed exhaust gas is then passed into the output pipe, which leads to the storage chamber. The cooling device in the storage chamber is activated to lower the temperature to below 31.3°C. At this point, the carbon dioxide in the exhaust gas liquefies and falls to the bottom of the storage chamber, where it is collected. Excess exhaust gas is discharged from the storage chamber through the exhaust pipe. This process completes the separation and collection of carbon dioxide from the exhaust gas, reducing carbon emissions, saving energy, and protecting the environment. 2. By installing filter baffles on the top and sides of the heat exchanger, the filter baffles filter the exhaust gas and remove particulate matter from the exhaust gas, thereby reducing the probability of particulate matter in the exhaust gas adhering to the heat exchanger and ensuring the heat exchange effect of the heat exchanger. 3. The temperature inside the storage chamber is sensed by a temperature sensor, and the sensed temperature signal is transmitted to the controller. The controller converts the temperature signal received from the temperature sensor into an electrical signal and transmits it to the solenoid valve to control the opening and closing of the solenoid valve. When the temperature sensor senses that the temperature inside the storage chamber is higher than 31.3℃, the controller controls the solenoid valve to increase the opening degree of the refrigerant pipe, so that the temperature inside the storage chamber is always kept below 31.3℃, ensuring the liquefaction effect of carbon dioxide in the storage chamber.

[0031] Reference Figure 1 The air intake device 2 includes a suction fan 21, an air intake pipe 22, and an air guide shroud 23. The suction fan 21 is fixedly connected to the frame 1. The air guide shroud 23 is fixedly connected to the suction fan 21. One end of the air intake pipe 22 is fixedly connected to the end of the suction fan 21 away from the air guide shroud 23 and communicates with the suction fan 21. The other end of the air intake pipe 22 communicates with the inside of the steam compressor 11. When the suction fan 21 is started, the exhaust gas, guided by the air guide shroud 23, enters the air intake pipe 22 through the suction fan 21, and the air intake pipe 22 then guides the exhaust gas into the steam compressor 11.

[0032] Reference Figure 1 and Figure 2 The steam compressor 11 comprises two parts: a compression chamber 41 and a power chamber 51. The compression chamber 41 is used to compress the exhaust gas, making the exhaust gas pressure greater than 7.38 MPa. The power chamber 51 is used to provide compression power to the compression chamber 41.

[0033] Reference Figure 2 and Figure 3 The compression chamber 41 includes a first housing 42, a rotating shaft 43, impellers 44, and diffuser guide vanes 45.

One end of the second driving air pipe 54 is fixedly connected to the second housing 52 and communicates with the air outlet, and the other end of the second driving air pipe 54 communicates with the inside of the air inlet pipe 22.

[0035] Reference Figure 2 and Figure 3 The pneumatic worm gear 55 is rotatably mounted inside the second housing 52. The drive worm gear 56 is rotatably mounted inside the first housing 42. One end of the drive worm 57 is located inside the second housing 52 and meshes with the pneumatic worm gear 55, while the other end of the drive worm 57 extends into the first housing 42 and meshes with the drive worm gear 56.

[0036] Reference Figure 1 and Figure 2 After the suction fan 21 draws the exhaust gas into the intake pipe 22, a portion of the exhaust gas entering the intake pipe 22 enters the second housing 52 through the first drive air pipe 53, and enters from the air inlet of the second housing 52 and exits from the air outlet. The pneumatic worm gear 55 located in the second housing 52 rotates under the action of the flowing exhaust gas. The rotation of the pneumatic worm gear 55 drives the drive worm 57 to rotate, the rotation of the drive worm 57 drives the drive worm wheel 56 to rotate, and the rotation of the drive worm wheel 56 drives the rotating shaft 43 to rotate.

[0037] Reference Figure 2 and Figure 3 The rotating shaft 43 drives the impeller 44 to rotate, and the rotating impeller 44 drives the diffuser guide vane 45 to rotate. The rotating diffuser guide vane 45 pressurizes the exhaust gas passing through the impeller 44. The pressurized exhaust gas enters the output pipe 13 and is introduced into the storage chamber 12.

[0038] Reference Figure 2 and Figure 4 The cooling device 3 includes a heat exchanger 31 and a condensation drip plate 32. The heat exchanger 31 is fixedly connected to the inner wall of the storage chamber 12. A refrigerant pipe 33 and a heat transfer pipe 34 are connected to the heat exchanger 31, and both the refrigerant pipe 33 and the heat transfer pipe 34 are equipped with solenoid valves. The condensation drip plate 32 is fixedly connected to the inner wall of the storage chamber 12 located below the heat exchanger 31. The condensation drip plate 32 is in an inclined state, with the height of the end of the condensation drip plate 32 away from the output pipe 13 being lower than the height of the end of the condensation drip plate 32 connected to the storage chamber 12, and a gap is left between the lower end of the condensation drip plate 32 and the inner wall of the storage chamber 12 for liquid carbon dioxide to flow down. A cavity is opened inside the condensation drip plate 32, and a first connecting pipe 61 and a second connecting pipe communicating with the cavity are fixedly connected to both ends of the condensation drip plate 32, respectively.

[0039] Reference Figure 2 and Figure 4 The heat exchanger 31 is activated to cool the temperature inside the storage chamber 12. The heat exchanger 31, in conjunction with the condenser plate 32, lowers the temperature inside the storage chamber 12 to below 31.3°C. This causes the carbon dioxide in the exhaust gas to liquefy and drip onto the condenser plate 32 after entering the storage chamber 12, due to the exhaust gas pressure being greater than 7.38 MPa and the temperature being lower than 31.3°C. The liquefied carbon dioxide then flows down the inclined surface of the condenser plate 32 and is collected at the bottom of the storage chamber 12. Reference Figure 2 and Figure 4A filter baffle 63 is provided on the inner wall of the storage chamber 12. The filter baffle 63 is divided into a first plate 64 and a second plate 65.

The second plate 65 is fixedly connected to the first plate 64 and is located between the heat exchanger 31 and the air outlet pipe 14. The second plate 65 is in a vertical state.

[0040] Reference Figure 4 A temperature sensor 66 is fixedly connected to the inner wall of the storage compartment 12, and a controller 67, which is electrically connected to both the temperature sensor 66 and the solenoid valve, is fixedly connected to the outer wall of the storage compartment 12. The temperature sensor 66 senses the temperature inside the storage compartment 12 and transmits the sensed temperature signal to the controller 67. The controller 67 converts the temperature signal received from the temperature sensor 66 into an electrical signal and transmits it to the solenoid valve to control its opening and closing. When the temperature sensor 66 senses that the temperature inside the storage compartment 12 is higher than 31.3°C, the controller 67 controls the solenoid valve to increase the opening degree of the refrigerant pipe 33, thereby keeping the temperature inside the storage compartment 12 below 31.3°C.

[0041] Reference Figure 1 and Figure 4 A liquid outlet pipe 68 is fixedly connected to the bottom of the storage chamber 12, and the liquid outlet pipe 68 communicates with the interior of the storage chamber 12. A switch valve is installed on the liquid outlet pipe 68. An observation window 69 is provided on the outer wall of the storage chamber 12 so that staff can observe the carbon dioxide collection inside the storage chamber 12.

[0042] The working principle of this application embodiment is as follows: The suction fan 21 starts to absorb the exhaust gas and inputs the absorbed exhaust gas into the steam compressor 11. The steam compressor 11 compresses the exhaust gas to a pressure greater than 7.38 MPa, and then passes the compressed exhaust gas into the output pipe 13. The output pipe 13 passes the exhaust gas into the storage chamber 12. The heat exchanger 31 in the storage chamber 12 starts to cool the storage chamber 12, so that the temperature inside the storage chamber 12 drops to below 31.3℃. At this time, the carbon dioxide in the exhaust gas liquefies and falls to the bottom of the storage chamber 12, and the storage chamber 12 collects the liquefied carbon dioxide.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
