Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to a photocatalytic oxidation treatment device for industrial waste gas. Background Technology

[0002] Industrial waste gas photocatalytic oxidation treatment equipment requires a microwave field cavity during operation. This cavity must be both closed off from the microwave field and allow for ventilation on both sides. It utilizes an aluminum honeycomb photocatalytic mesh plate, and two rows of electrodeless dedicated UVC lamps are installed inside the cavity. A ceramic photocatalytic mesh plate is installed between the two rows of lamps to enhance the generation of hydroxyl radicals. A microwave head radiating microwave energy and a switching power supply providing power are installed outside the cavity. When the power is turned on and the module is operating, a microwave electromagnetic field, UVC rays, hydroxyl radicals, and electron-hole pairs are simultaneously generated within the cavity. Organic waste gas molecules entering the module's cavity are simultaneously subjected to the triple catalytic oxidation effect of the microwave field, UVC rays, and hydroxyl radicals, ultimately producing harmless H2O and CO2, with very little residual VOCs molecules and intermediate small molecule harmful substances.

[0003] In the prior art, such as Chinese Patent No. CN110227335A, there is an industrial waste gas photocatalytic oxidation treatment device and its treatment process. This device includes a housing, a filter module, a photocatalytic oxidation module, and an ozone treatment module disposed within the housing. The front end of the housing has a waste gas inlet, and the rear end has a purified gas outlet. The treatment process includes using the industrial waste gas photocatalytic oxidation treatment device as described in claim 7 to decompose and purify the industrial waste gas. This invention can effectively purify the residual ozone generated during the decomposition and purification process; the housing is equipped with a primary photocatalytic oxidation module and a deep decomposition photocatalytic oxidation module, and the ultraviolet lamps in each adjacent row are arranged in a staggered manner, improving the purification efficiency of the industrial waste gas; the filter cloth, catalyst plate, and ozone decomposition plate are detachably disposed within the housing for easy replacement.

[0004] However, while the aforementioned patents possess the technical advantages described above, their disadvantage lies in the fact that during the photocatalytic oxidation process, the internal temperature of the equipment rises due to electromagnetic radiation, moisture absorbs heat and vaporizes into water vapor, and the temperature of carbon dioxide gas increases. If the mixed waste gas is directly discharged, water vapor will adhere to the outside of the equipment. Since photocatalytic oxidation equipment is a precision device, a large amount of water droplets adhering to it can cause a circuit break. The usual practice is to add a waterproof layer to the outside of the equipment. Although this can prevent water vapor intrusion, the waterproof layer will isolate the heat conduction between the inside and outside of the equipment, affecting the normal heat dissipation of the equipment. The temperature of the discharged mixed gas is still very high, which can easily cause localized high temperatures. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the technical solution adopted by this invention is as follows: an industrial waste gas photocatalytic oxidation treatment device, comprising a cavity, a treatment device fixedly connected to the inner surface of the top of the cavity, the treatment device including a suction device, a circulation device rotatably connected to the outer surface of the suction device via a belt, a flow device arranged on the right side of the circulation device, a base arranged at the bottom of the flow device, and air inlet slots opened in the walls on both sides of the base. The waste gas undergoes photocatalytic oxidation inside the cavity, during which the waste gas is converted into water and carbon dioxide. Subsequently, the suction device draws upward, and the water vapor and carbon dioxide mixture inside the cavity enters the interior of the flow device from the air inlet slots on both sides of the base.

[0006] The suction device includes a motor, a bracket is fixedly connected to the outer surface of the motor, a large wheel is provided on the outside of the bracket, a drive shaft is fixedly connected to the inner surface of the large wheel, a turbine is fixedly connected to the outer surface of the drive shaft, a telescopic rod is provided at the bottom of the turbine, and a cover plate is fixedly connected to the bottom end of the telescopic rod. The mixed gas flows upward inside the flow device, and the circulation device reduces the temperature of the mixed gas through water cooling circulation. During the upward flow of the mixed gas, cold air from the outside enters the interior of the flow device, mixes with the mixed gas, and flows through gas cooling to complete the cooling. The multi-stage cooling has a good effect.

[0007] In a preferred embodiment, the outer surface of the telescopic rod is slidably connected to the inner surface of the drive shaft, and the outer surface of the top end of the drive shaft is rotatably connected to the inner surface of the motor. The motor outside the bracket drives the drive shaft to rotate, and the rotating drive shaft drives the large wheel and turbine to rotate, thereby reducing the air pressure inside the machine body.

[0008] In a preferred embodiment, the circulation device includes a small wheel, a rotating shaft fixedly connected to the inner surface of the small wheel, a screw fixedly connected to the outer surface of the rotating shaft, a sealing cylinder rotatably connected to the outer surface of the screw, a drain pipe fixedly connected to the inner surface of the sealing cylinder, a heat dissipation plate at the bottom of the drain pipe, a water inlet pipe at the bottom of the heat dissipation plate, a water outlet pipe at the top of the water inlet pipe, and a spiral tube fixedly connected to the top of the water outlet pipe. The air pressure difference forces the telescopic rod to retract into the drive shaft, causing the cover plate to move upwards and its lower surface to separate from the inner surface of the base. The mixed gas inside the base enters the interior of the machine. The suction device, through a single drive unit, drives the entire device to operate, resulting in energy saving, environmental protection, and low cost.

[0009] In a preferred embodiment, the outer surface of the small wheel is rotatably connected to the inner surface of the belt, the inner surface of the belt is rotatably connected to the outer surface of the large wheel, the outer surface of the rotating shaft is rotatably connected to the inner surface of the sealing cylinder, the inner surface of the sealing cylinder is fixedly connected to the left end of the inlet pipe, and the inner surface of the sealing cylinder is fixedly connected to the bottom end of the outlet pipe. The large wheel drives the small wheel to rotate via the belt, and the rotating small wheel drives the screw to rotate via the rotating shaft. The screw rotates along the inner surface of the sealing cylinder, reducing the pressure inside the sealing cylinder. Water flows from the inner surface of the inlet pipe from right to left into the interior of the sealing cylinder, and then flows upward along the inner wall of the sealing cylinder to the outlet pipe, until it flows into the interior of the spiral tube.

[0010] In a preferred embodiment, the flow device includes a body, a top plate fixedly connected to the upper surface of the body, an exhaust trough at the bottom of the top plate, a flow guide plate at the bottom of the exhaust trough, a heat dissipation sleeve outside the flow guide plate, a water outlet trough outside the heat dissipation sleeve, an inclined plate at the bottom of the water outlet trough, a bottom plate fixedly connected to the outer surface of the inclined plate, a baffle ring outside the bottom plate, and a cold air hole outside the baffle ring. When the water flows upward along the inner surface of the sealed cylinder, the temperature of the hot water is conducted to the interior of the heat dissipation plate through the solid, and then diffused to the external environment through the heat dissipation plate, thus cooling the hot water. After the water flow completes five cycles, the water outlet pipe is closed, and the water flows out from the drain pipe to the water storage tank. The water vapor completes heat exchange while being stored and collected.

[0011] In a preferred embodiment, the inner surface of the machine body is fixedly connected to the outer surface of the inclined plate, and the inner surface of the machine body is slidably connected to the outer surface of the retaining ring. The cooling air hole is opened in the wall of the machine body. Under the suction of the turbine, the mixed gas flows upward along the inner surface of the machine body. During this process, the retaining ring slides upward, and the outside cold air enters the interior of the machine body through the cooling air hole and mixes with the mixed gas. The cold air assists in cooling water vapor and carbon dioxide. The water vapor flows upward along the inner wall of the machine body, and the water vapor attached to the outer surface of the turbine is thrown to the inner wall of the machine body under the action of centrifugal force.

[0012] In a preferred embodiment, the inner surface of the body is fixedly connected to the outer surface of the drainage plate, and the outer surface of the body is fixedly connected to the inner surface of the heat dissipation sleeve. The exhaust groove is opened in the top wall of the body, and the water outlet groove is opened in the bottom wall of the body. Residual water vapor, carbon dioxide and air are discharged from the exhaust groove to the bottom of the top plate. Under the obstruction of the top plate, the water vapor gathers and drips down to the outer surface of the heat dissipation sleeve, and finally drips into the interior of the bottom plate to cool the outer surface of the heat dissipation sleeve.

[0013] In a preferred embodiment, the inner surface of the heat dissipation sleeve is fixedly connected to the outer surface of the spiral tube. The bottom end of the spiral tube penetrates the bottom of the heat dissipation sleeve and extends into the space inside the base plate. The inner surface of the machine body is rotatably connected to the outer surface of the drive shaft. At the same time, cold water flows inside the spiral tube inside the heat dissipation sleeve, further reducing the temperature. As the mixed gas flows upward along the inner wall of the machine body, the heat from the water vapor and hot gas is transferred to the interior of the heat dissipation sleeve through solid heat conduction. Since there is fluid circulation inside and outside the heat dissipation sleeve, there is always a temperature difference between it and the machine body, so that the heat dissipation sleeve always maintains a heat dissipation state.

[0014] In a preferred embodiment, the turbine is located inside the machine body, the lower surface of the sealing cylinder is fixedly connected to the upper surface of the base, the outer surface of the cover plate is slidably connected to the inner surface of the base, and the outer surface of the right end of the water inlet pipe is fixedly connected to the inner surface of the base plate. Water vapor releases heat and liquefies, and water droplets drip downwards under the guidance of the guide plate, along the outer surface of the inclined plate, and are discharged into the interior of the base plate through the water outlet trough. Finally, all the water vapor releases heat and liquefies, and is temporarily stored inside the base plate. The water inlet pipe draws the water flow back from the bottom end of the spiral tube to the interior of the base plate. After cooling, carbon dioxide and air float upwards to the outside because their density is less than that of water. The equipment completes the separation of water vapor and carbon dioxide.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention, through the setting of a treatment device, allows waste gas to undergo photocatalytic oxidation inside the cavity when the equipment is in use. During this process, the waste gas is converted into water and carbon dioxide. Subsequently, the suction device draws it upward, and the water vapor and carbon dioxide mixture inside the cavity enters the interior of the flow device from the air inlet slots on both sides of the base. The mixed gas flows upward inside the flow device, and the circulation device lowers the temperature of the mixed gas through water cooling circulation. During the upward flow of the mixed gas, cold air from the outside enters the interior of the flow device, mixes with the mixed gas, and flows. The cooling is completed through gas cooling, achieving a multi-stage cooling effect.

[0017] 2. This invention incorporates a suction device. When the device is in use, a motor outside the support drives a drive shaft to rotate. The rotating drive shaft drives the large wheel and turbine to rotate, reducing the air pressure inside the machine body. This pressure difference forces the telescopic rod to retract into the drive shaft, causing the cover plate to move upwards and its lower surface to separate from the inner surface of the base. The mixed gas inside the base enters the machine body. The suction device drives the entire device through a single drive unit, resulting in energy saving, environmental protection, and low cost.

[0018] 3. This invention incorporates a circulation device. When the equipment is in use, the large wheel drives the small wheel to rotate via a belt. The rotating small wheel drives the screw to rotate via a shaft. The screw rotates along the inner surface of the sealing cylinder, reducing the pressure inside the sealing cylinder. Water flows from right to left from the inner surface of the inlet pipe into the interior of the sealing cylinder. Subsequently, the water flows upward along the inner wall of the sealing cylinder to the outlet pipe, and finally into the spiral tube. As the water flows upward along the inner surface of the sealing cylinder, the temperature of the hot water is conducted to the interior of the heat dissipation plate through the solid, and then diffused to the external environment through the heat dissipation plate, thus cooling the hot water. After the water flow completes five cycles, the outlet pipe is closed, and the water flows out through the drain pipe to the storage tank. Water vapor completes heat exchange while being stored and collected.

[0019] 4. This invention, through the installation of a flow device, allows the mixed gas to flow upwards along the inner surface of the machine body under the suction of the turbine during operation. During this process, the baffle ring slides upwards, allowing outside cold air to enter the machine body through the cold air vents and mix with the mixed gas. The cold air assists in cooling water vapor and carbon dioxide. The water vapor flows upwards along the inner wall of the machine body, and the water vapor adhering to the outer surface of the turbine is thrown to the inner wall of the machine body under centrifugal force. The remaining water vapor, carbon dioxide, and air are discharged from the exhaust chute to the bottom of the top plate. Blocked by the top plate, the water vapor collects and drips downwards onto the outer surface of the heat dissipation sleeve, eventually dripping into the interior of the bottom plate, thus cooling the outer surface of the heat dissipation sleeve. Simultaneously, cold water flows inside the spiral tube within the heat dissipation sleeve. The temperature is further reduced, and as the mixed gas flows upward along the inner wall of the machine, the heat of the water vapor and hot air is transferred to the interior of the heat dissipation sleeve through solid heat conduction. Since there is fluid circulation inside and outside the heat dissipation sleeve, there is always a temperature difference with the machine body, so the heat dissipation sleeve is always in a heat dissipation state. The water vapor releases heat and liquefies, and the water droplets drip downward under the guidance of the guide plate, along the outer surface of the inclined plate, and are discharged into the interior of the bottom plate through the water outlet. Finally, all the water vapor releases heat and liquefies, and is temporarily stored inside the bottom plate. The water inlet pipe draws the water flow and returns it to the interior of the bottom plate from the bottom end of the spiral tube. After the carbon dioxide and air have been cooled, they float upward to the outside because their density is less than that of water. The equipment completes the separation of water vapor and carbon dioxide. Attached Figure Description

[0029] Example 1:

[0030] Please see Figure 1 - Figure 7 This invention provides a technical solution: an industrial waste gas photocatalytic oxidation treatment device, comprising a cavity 1, a treatment device 2 fixedly connected to the inner surface of the top of the cavity 1, the treatment device 2 including a suction device 3, a circulation device 5 rotatably connected to the outer surface of the suction device 3 via a belt 4, a flow device 6 provided on the right side of the circulation device 5, a base 7 provided at the bottom of the flow device 6, and air inlet slots 8 formed in the walls on both sides of the base 7; the suction device 3 includes a motor 30, a bracket 31 fixedly connected to the outer surface of the motor 30, a large wheel 32 provided on the outside of the bracket 31, a drive shaft 33 fixedly connected to the inner surface of the large wheel 32, a turbine 34 fixedly connected to the outer surface of the drive shaft 33, a telescopic rod 35 provided at the bottom of the turbine 34, and a cover plate 36 fixedly connected to the bottom end of the telescopic rod 35. The outer surface of the telescopic rod 35 is slidably connected to the inner surface of the drive shaft 33, and the outer surface of the top end of the drive shaft 33 is rotatably connected to the inner surface of the motor 30.

[0031] The exhaust gas undergoes photocatalytic oxidation inside the cavity 1, during which it is converted into water and carbon dioxide. Subsequently, the suction device 3 draws the gas upward, and the mixture of water vapor and carbon dioxide inside the cavity 1 enters the flow device 6 from the air inlet slots 8 on both sides of the base 7. The mixed gas flows upward inside the flow device 6, and the circulation device 5 lowers the temperature of the mixed gas through water cooling circulation. During the upward flow of the mixed gas, cold air from the outside enters the flow device 6 and mixes with the mixed gas. The cooling is achieved through gas cooling, resulting in a multi-stage cooling effect.

[0032] The circulation device 5 includes a small wheel 50, a rotating shaft 51 fixedly connected to the inner surface of the small wheel 50, a screw 52 fixedly connected to the outer surface of the rotating shaft 51, a sealing cylinder 53 rotatably connected to the outer surface of the screw 52, ​​a drain pipe 54 fixedly connected to the inner surface of the sealing cylinder 53, a heat dissipation plate 55 at the bottom of the drain pipe 54, a water inlet pipe 56 at the bottom of the heat dissipation plate 55, a water outlet pipe 57 at the top of the water inlet pipe 56, and a spiral tube 58 fixedly connected to the top of the water outlet pipe 57.

[0033] The motor 30 outside the bracket 31 drives the drive shaft 33 to rotate. The rotating drive shaft 33 drives the large wheel 32 and the turbine 34 to rotate. The air pressure inside the machine body 60 decreases. The air pressure difference forces the telescopic rod 35 to retract into the drive shaft 33. The cover plate 36 moves upward and its lower surface separates from the inner surface of the base 7. The mixed gas inside the base 7 enters the interior of the machine body 60. The suction device 3 drives the entire equipment to operate through a single drive device. It is energy-saving, environmentally friendly, and has a low cost.

[0034] The flow device 6 includes a body 60. A top plate 61 is fixedly connected to the upper surface of the body 60. An exhaust trough 62 is provided at the bottom of the top plate 61. A flow guide plate 63 is provided at the bottom of the exhaust trough 62. A heat dissipation sleeve 64 is provided outside the flow guide plate 63. A water outlet trough 65 is provided outside the heat dissipation sleeve 64. An inclined plate 66 is provided at the bottom of the water outlet trough 65. A bottom plate 67 is fixedly connected to the outer surface of the inclined plate 66. A baffle ring 68 is provided outside the bottom plate 67. A cold air hole 69 is provided outside the baffle ring 68. The inner surface of the body 60 is fixedly connected to the outer surface of the inclined plate 66, and the inner surface of the body 60 is slidably connected to the outer surface of the baffle ring 68. The cold air hole 69 is formed in the wall of the body 60.

[0035] The large wheel 32 drives the small wheel 50 to rotate via the belt 4. The rotating small wheel 50 drives the screw 52 to rotate via the shaft 51. The screw 52 rotates along the inner surface of the sealing cylinder 53, reducing the pressure inside the sealing cylinder 53. Water flows from the inner surface of the inlet pipe 56 from right to left into the interior of the sealing cylinder 53. Then, the water flows upward along the inner wall of the sealing cylinder 53 to the outlet pipe 57, until it flows into the interior of the spiral tube 58. As the water flows upward along the inner surface of the sealing cylinder 53, the temperature of the hot water is conducted to the interior of the heat dissipation plate 55 through the solid, and then diffused to the external environment through the heat dissipation plate 55. The hot water is cooled down. After the water flow completes five cycles, the outlet pipe 57 is closed, and the water flows out from the drain pipe 54 to the water storage tank. The water vapor completes heat exchange while being stored and collected.

[0036] The inner surface of the body 60 is fixedly connected to the outer surface of the diversion plate 63, and the outer surface of the body 60 is fixedly connected to the inner surface of the heat dissipation sleeve 64. The exhaust groove 62 is formed in the top wall of the body 60, and the water outlet groove 65 is formed in the bottom wall of the body 60. The inner surface of the heat dissipation sleeve 64 is fixedly connected to the outer surface of the spiral tube 58. The bottom end of the spiral tube 58 passes through the bottom of the heat dissipation sleeve 64 and extends into the space inside the base plate 67. The inner surface of the body 60 is rotatably connected to the outer surface of the drive shaft 33. The turbine 34 is located inside the body 60. The lower surface of the sealing cylinder 53 is fixedly connected to the upper surface of the base 7. The outer surface of the cover plate 36 is slidably connected to the inner surface of the base 7. The outer surface of the right end of the water inlet pipe 56 is fixedly connected to the inner surface of the base plate 67.

[0037] Under the suction of turbine 34, the mixed gas flows upward along the inner surface of the casing 60. During this process, the baffle ring 68 slides upward, and outside cold air enters the interior of the casing 60 through the cold air vent 69, mixing with the mixed gas. The cold air assists in cooling water vapor and carbon dioxide. The water vapor flows upward along the inner wall of the casing 60. The water vapor adhering to the outer surface of turbine 34 is thrown to the inner wall of the casing 60 under the action of centrifugal force. The remaining water vapor, carbon dioxide, and air are discharged from exhaust slot 62 to the bottom of top plate 61. Under the obstruction of top plate 61, the water vapor gathers and drips downward onto the outer surface of heat dissipation sleeve 64, and finally drips into the interior of bottom plate 67, cooling the outer surface of heat dissipation sleeve 64. At the same time, cold water flows inside the spiral tube 58 inside heat dissipation sleeve 64, further reducing the temperature. As the mixed gas flows upward along the inner wall of the body 60, the heat from the water vapor and hot air is transferred to the interior of the heat dissipation sleeve 64 through solid heat conduction. Since there is fluid circulation inside and outside the heat dissipation sleeve 64, there is always a temperature difference between it and the body 60, so the heat dissipation sleeve 64 is always in a heat dissipation state. The water vapor releases heat and liquefies, and the water droplets drip downward under the guidance of the guide plate 63. They are discharged into the interior of the bottom plate 67 along the outer surface of the inclined plate 66 and through the water outlet 65. Finally, all the water vapor releases heat and liquefies, and is temporarily stored inside the bottom plate 67. The water inlet pipe 56 draws the water flow and returns it to the interior of the bottom plate 67 from the bottom end of the spiral tube 58. After the carbon dioxide and air have cooled down, they float upward to the outside because their density is less than that of water. The equipment completes the separation of water vapor and carbon dioxide.

[0038] Working principle:

[0039] When the equipment is in use, the exhaust gas undergoes photocatalytic oxidation inside the chamber 1. During this process, the exhaust gas is converted into water and carbon dioxide. Subsequently, the suction device 3 draws the gas upward. The water vapor and carbon dioxide mixture inside the chamber 1 enters the flow device 6 from the air inlet slots 8 on both sides of the base 7. The mixed gas flows upward inside the flow device 6. The circulation device 5 lowers the temperature of the mixed gas through water cooling circulation. During the upward flow of the mixed gas, cold air from the outside enters the flow device 6 and mixes with the mixed gas. The cooling is achieved through gas cooling, resulting in a multi-stage cooling effect.

[0040] The motor 30 outside the bracket 31 drives the drive shaft 33 to rotate. The rotating drive shaft 33 drives the large wheel 32 and the turbine 34 to rotate. The air pressure inside the machine body 60 decreases. The air pressure difference forces the telescopic rod 35 to retract into the drive shaft 33. The cover plate 36 moves upward and its lower surface separates from the inner surface of the base 7. The mixed gas inside the base 7 enters the interior of the machine body 60. The suction device 3 drives the entire equipment to operate through a single drive device. It is energy-saving, environmentally friendly, and has a low cost.

[0041] The large wheel 32 drives the small wheel 50 to rotate via the belt 4. The rotating small wheel 50 drives the screw 52 to rotate via the shaft 51. The screw 52 rotates along the inner surface of the sealing cylinder 53, reducing the pressure inside the sealing cylinder 53. Water flows from the inner surface of the inlet pipe 56 from right to left into the interior of the sealing cylinder 53. Then, the water flows upward along the inner wall of the sealing cylinder 53 to the outlet pipe 57, until it flows into the interior of the spiral tube 58. As the water flows upward along the inner surface of the sealing cylinder 53, the temperature of the hot water is conducted to the interior of the heat dissipation plate 55 through the solid, and then diffused to the external environment through the heat dissipation plate 55. The hot water is cooled down. After the water flow completes five cycles, the outlet pipe 57 is closed, and the water flows out from the drain pipe 54 to the water storage tank. The water vapor completes heat exchange while being stored and collected.

[0042] Under the suction of turbine 34, the mixed gas flows upward along the inner surface of the casing 60. During this process, the baffle ring 68 slides upward, and outside cold air enters the interior of the casing 60 through the cold air vent 69, mixing with the mixed gas. The cold air assists in cooling water vapor and carbon dioxide. The water vapor flows upward along the inner wall of the casing 60. The water vapor adhering to the outer surface of turbine 34 is thrown to the inner wall of the casing 60 under the action of centrifugal force. The remaining water vapor, carbon dioxide, and air are discharged from exhaust slot 62 to the bottom of top plate 61. Under the obstruction of top plate 61, the water vapor gathers and drips downward onto the outer surface of heat dissipation sleeve 64, and finally drips into the interior of bottom plate 67, cooling the outer surface of heat dissipation sleeve 64. At the same time, cold water flows inside the spiral tube 58 inside heat dissipation sleeve 64, further reducing the temperature. As the mixed gas flows upward along the inner wall of the body 60, the heat from the water vapor and hot air is transferred to the interior of the heat dissipation sleeve 64 through solid heat conduction. Since there is fluid circulation inside and outside the heat dissipation sleeve 64, there is always a temperature difference between it and the body 60, so the heat dissipation sleeve 64 is always in a heat dissipation state. The water vapor releases heat and liquefies, and the water droplets drip downward under the guidance of the guide plate 63. They are discharged into the interior of the bottom plate 67 along the outer surface of the inclined plate 66 and through the water outlet 65. Finally, all the water vapor releases heat and liquefies, and is temporarily stored inside the bottom plate 67. The water inlet pipe 56 draws the water flow and returns it to the interior of the bottom plate 67 from the bottom end of the spiral tube 58. After the carbon dioxide and air have cooled down, they float upward to the outside because their density is less than that of water. The equipment completes the separation of water vapor and carbon dioxide.
