Description

Technical Field

[0001] This invention relates to the field of environmental monitoring technology, and in particular to a real-time atmospheric environmental quality monitoring device. Background Technology

[0002] Existing real-time air quality monitoring devices typically include a sampling unit, an analysis unit, and a control unit. They usually use a sampling pump to draw ambient air, which is then transported to the analysis and detection unit via sampling tubes to achieve real-time online monitoring of various air pollutants. Current devices generally employ heated sampling tubes to prevent water vapor condensation and are equipped with necessary protective structures, forming the basic technical solution for current automatic ambient air quality monitoring.

[0003] However, the existing devices still have significant drawbacks that affect monitoring accuracy in practical applications. First, in extremely humid environments or when the heating system experiences slight fluctuations, condensation inevitably forms on the inner wall of the sampling tube. This accumulated condensation rapidly absorbs and dissolves water-soluble pollutants such as SO2, NO2, and NH3 in the gas flow, resulting in significantly lower measured concentrations and causing persistent monitoring errors. Second, during the routine treatment of the condensate, a uniform thin water film may remain on the smooth tube wall. This water film continues to absorb the target gas, and its large surface area stores more pollutants, causing repeated adsorption and desorption of the gas. This leads to a lag response and memory effect in the monitoring data, severely limiting the accuracy and reliability of the monitoring results.

[0004] Therefore, it is necessary to invent a real-time atmospheric environmental quality monitoring device to solve the above problems. Summary of the Invention

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] Reference Figure 1 - Figure 9A real-time atmospheric environmental quality monitoring device includes a monitoring cabinet 1. A sampling head 2 is fixedly installed on the top left side of the monitoring cabinet 1, and a sampling pipe 3 is fixedly installed on the top right side of the monitoring cabinet 1. A sampling pump connected to the sampling pipe 3 is installed inside the monitoring cabinet 1. The sampling pump draws external gas into the monitoring cabinet 1 for detection through the sampling pipe 3. The sampling pipe 3 is shaped like an inverted U. The horizontal section of the sampling pipe 3 is higher than the top of the monitoring cabinet 1, and the bottom of the sampling pipe 3 is lower than the top of the monitoring cabinet 1. The bottom wall of the horizontal section of the sampling pipe 3 is inclined, gradually decreasing in height towards the collection pipe 4 to facilitate the flow of condensate to the collection pipe 4. The internal components also include: a collection short tube 4, which is fixedly installed at the bottom of the middle section of the sampling pipe 3. The collection short tube 4 is connected to the bottom of the horizontal section of the sampling pipe 3. A buoyancy ball 43 is slidably connected inside the collection short tube 4. The buoyancy ball 43 is made of polytetrafluoroethylene, which is corrosion-resistant and ensures that it can float even with a small amount of condensate. The buoyancy ball 43 is slidably connected to the surface of the vertical guide rod 41. A sliding rod 55 is slidably connected inside the bottom of the collection short tube 4. A drainage groove 56 is opened in the middle of the sliding rod 55. A piston block 6 is slidably connected inside the middle section of the sampling pipe 3. A baffle 66 is fixedly connected to the right side of the piston block 6. A connecting pipe 63 is fixedly installed inside the piston block 6.

[0036] Specifically, when condensate accumulates inside the sampling pipe 3, it gradually flows into the collecting short pipe 4. At this time, the buoyancy ball 43 moves upward under the buoyancy of the condensate, thereby pulling the sliding rod 55 upward until the top of the drain trough 56 moves into the collecting short pipe 4, so that the inside and outside of the collecting short pipe 4 are connected through the drain trough 56. That is, the condensate inside the collecting short pipe 4 can be discharged through the drain trough 56.

[0037] In actual use, the operator can install a container for collecting condensate at the bottom of the sampling pipe 3, which is located at the bottom end of the collecting short pipe 4. This allows the condensate to be collected by the container after being discharged through the drain trough 56, thus preventing condensate from dripping onto the equipment.

[0038] Reference Figure 4A vertical guide rod 41 is fixedly installed in the middle of the inside of the collecting short pipe 4. A buoyancy ball 43 is slidably connected to the surface of the vertical guide rod 41. A tension spring 42 is fixedly installed at the bottom of the buoyancy ball 43. The bottom end of the tension spring 42 is fixedly installed on the bottom wall of the collecting short pipe 4. The tension spring 42 is sleeved on the surface of the vertical guide rod 41. A connecting rod 44 is fixedly installed at the top of the buoyancy ball 43. A push rod 45 is rotatably connected to the top of the connecting rod 44. An arc plate 46 is fixedly installed inside the top of the collecting short pipe 4. The arc plate 46 is fixedly installed at the top of the vertical guide rod 41 to ensure stability during installation. The height of the arc plate 46 gradually decreases from the middle to the edge. A groove for condensate flow is opened on the surface of the arc plate 46. The connecting rod 44 extends through the arc plate 46 to the outside of the collecting short pipe 4.

[0039] Reference Figure 4 - Figure 5 The inner wall of the collecting short tube 4 has a cross groove 5, the bottom end of which is flush with the bottom wall of the collecting short tube 4. A slider 51 is slidably connected inside the cross groove 5. A spring piece 52 is fixedly installed on the bottom wall of the collecting short tube 4. The spring piece 52 has three weakened bends to support and buffer the descending slider 51. The spring piece 52 is made of stainless steel to prevent rusting inside the damp collecting short tube 4. A connecting plate 53 is fixedly installed on the top of the slider 51. A driven block 54 is fixedly installed on the bottom end of the connecting plate 53 away from the slider 51. The bottom of the moving block 54 is arc-shaped and fits snugly against the surface of the buoyancy ball 43. When the buoyancy ball 43 moves upward, it pushes the driven block 54 to move upward as well. A vertical groove is provided at the bottom end of the collecting short tube 4. The sliding rod 55 is slidably connected inside the vertical groove and extends to the bottom of the collecting short tube 4. The height of the drain trough 56 is greater than the height of the vertical groove. The drain trough 56 is used to drain the condensate in the collecting short tube 4. Its height is greater than that of the vertical groove to ensure smooth drainage and avoid residue. The condensate inside the collecting short tube 4 will be discharged through the drain trough 56 and the vertical groove.

[0040] Specifically, when condensate flows into the collection short pipe 4, the buoyancy ball 43 moves upward under buoyancy. At this time, the buoyancy ball 43 stretches the tension spring 42 and pushes the driven block 54 upward. The driven block 54 then drives the slider 51 to slide inside the cross groove 5 via the connecting plate 53. The slider 51 then drives the sliding rod 55 upward. During this process, the drain trough 56 remains below the collection short pipe 4, meaning the condensate remains inside the collection short pipe 4 and cannot be discharged. During this process, the buoyancy ball 43 also pushes the push rod 45 upward via the connecting rod 44. As the bottom of the push rod 45 moves upward, it pushes the top-rotating horizontal connecting rod 61. Since the horizontal connecting rod 61 and the piston block 6 are fixedly connected and the piston block 6 slides inside the sampling pipe 3, the piston block 6 cannot move up and down but can only move left and right. The push rod 45 located on the lower left side of the piston block 6 will push the piston block 6 to the right. At this time, the piston block 6 will slide in the horizontal section inside the sampling pipe 3. The piston block 6 will push the condensate in the horizontal section inside the sampling pipe 3, so that the condensate is pushed to the vertical section on the right side of the sampling pipe 3, thereby pushing out the condensate inside the sampling pipe 3. As the piston block 6 continues to move to the right, the buoyancy ball 43 will also drive the sliding rod 55 to move upward. After the piston block 6 has cleaned the condensate accumulated inside the sampling pipe 3, the sliding rod 55 will also move upward to the top of the drain trough 56 inside the collecting short pipe 4. At this time, the inside and outside of the collecting short pipe 4 are connected through the drain trough 56. The condensate accumulated at the bottom of the collecting short pipe 4 will be discharged downward through the drain trough 56, thus completing the treatment of the condensate inside the collecting short pipe 4 and the sampling pipe 3.

[0041] Reference Figure 6 - Figure 8A horizontal connecting rod 61, which is rotatably connected to the top of the push rod 45, is fixedly connected to the left side of the piston block 6. When the bottom of the push rod 45 moves upward, its top exerts a force to the upper right on the horizontal connecting rod 61. Since the piston block 6 slides inside the sampling pipe 3 and can only move in the left and right directions, the upward component of the force exerted by the push rod 45 on the horizontal connecting rod 61 cannot push the piston block 6 to move, while the rightward component will push the piston block 6 to move to the right. An arc-shaped groove 62 is provided inside the bottom of the piston block 6, and an exhaust duct is provided at the bottom of the connecting pipe 63 facing away from the monitoring cabinet 1. During the movement of the piston block 6, the airflow is discharged through the inclined exhaust duct and blown towards the bottom wall of the sampling pipe 3, thereby cleaning the bottom wall of the sampling pipe 3. The residual water film is blown in the direction of piston block 6 movement, thereby cleaning the residual water film out of the sampling pipe 3. The connecting pipe 63 is fixedly installed inside piston block 6. An exhaust trough is opened at the bottom of the connecting pipe 63. Inclined guide plates 64 are fixedly installed on both sides of the bottom of the connecting pipe 63 at the exhaust trough. The guide plates 64 can guide the exhaust airflow so that the airflow can be blown directly to the bottom wall of the sampling pipe 3. A hose 65 is fixedly connected to the top of the connecting pipe 63. The hose 65 is fixed to the connecting pipe 63 by clamps. The connection is sealed with sealant to prevent gas leakage. The top of the sampling pipe 3 has a top groove that matches the size of the hose 65. An air pump for supplying air is installed at the top of the sampling pipe 3.

[0042] Specifically, since the condensate generated on the inner wall of the sampling pipe 3 drips downwards under the action of gravity, the condensate mainly accumulates at the bottom wall of the horizontal section of the sampling pipe 3. Therefore, the condensate can be cleaned by the piston block 6, which is set in a semi-circular shape. The gas pumped out by the air pump enters the interior of the connecting pipe 63 through the hose 65, and then is discharged through the exhaust slot at its bottom. Under the guidance of the guide plate 64, the gas is blown towards the inner wall of the sampling pipe 3. At this time, the sprayed gas can clean the water film remaining on the inner wall of the sampling pipe 3, so as to avoid the residual water film affecting the detection accuracy of the gas.

[0043] Reference Figure 8 - Figure 9A ball valve 7 is installed inside the flexible hose 65. The ball valve 7 consists of a valve body located inside the flexible hose 65 and a valve stem for controlling the switch. The valve stem extends through the flexible hose 65 and beyond it. A sealing ring for waterproofing is installed at the point where the valve stem passes through the flexible hose 65. A limit block 1 is fixedly installed on the surface of the ball valve 7, and a limit block 2 that is adapted to and in contact with the limit block 1 is fixedly installed on the surface of the flexible hose 65. The angle between the limit block 1 and the limit block 2 is set so that when the two are in contact, the valve stem drives the valve body to rotate, controlling the connection status of the flexible hose 65. A driven bevel gear 71 is fixedly mounted on the valve stem surface of the ball valve 7. A rotating rod 72 is rotatably connected to the top of the piston block 6. A driving bevel gear 73 is fixedly connected to the surface of the rotating rod 72. A rotating wheel 74 is fixedly connected to the surface of the rotating rod 72. A rotating ring 75 is provided on the surface of the rotating wheel 74. The driven bevel gear 71 and the driving bevel gear 73 are meshed together. The rotating ring 75 is rotatably connected to the inner wall of the sampling pipe 3. The rotating ring 75 can rotate on the surface of the rotating wheel 74. The rotating ring 75 can drive the rotating wheel 74 to rotate through friction.

[0044] Specifically, when the piston block 6 moves to process the condensate in the horizontal section of the sampling pipe 3, the piston block 6 will drive the rotating wheel 74 at the top to move. During the movement of the rotating wheel 74, the rotating ring 75 will rotate due to the friction of the inner wall of the sampling pipe 3. At this time, the rotating ring 75 will drive the rotating wheel 74 to rotate through the friction. The rotating wheel 74 will then drive the rotating rod 72 and the active bevel gear 73 to rotate, causing the active bevel gear 73 to drive the meshing driven bevel gear 71 to rotate. When the driven bevel gear 71 rotates, it will drive the valve stem of the ball valve 7 to rotate, so that the valve body is in the open state inside the hose 65. Thus, the inside of the hose 65 is in a connected state. Under the mutual restriction of the limiting block 1 and the limiting block 2, the valve stem cannot continue to rotate after rotating 90 degrees, maintaining the connected state inside the hose 65. At this time, the rotating wheel 74 cannot continue to rotate. If the rotating wheel 74 is unable to rotate due to external force, as the piston block 6 continues to move, the rotating ring 75 will overcome the friction between itself and the rotating wheel 74 and rotate on the surface of the rotating wheel 74.

[0045] Reference Figure 1 - Figure 3 A heat tracing heater 8 is fixedly installed on the bottom surface of the sampling pipe 3 on the side away from the monitoring cabinet 1. The heat tracing heater 8 can heat the bottom air inlet section of the sampling pipe 3, thereby effectively preventing humid air from liquefying and producing condensate on the inner wall of the sampling pipe 3.

[0046] In this invention, during the process of monitoring the gas in the environment through the sampling head 2, the sampling pump can be turned on to draw the external gas into the sampling pipe 3, and then the gas enters the monitoring cabinet 1 for detection. At this time, the heat tracing heater 8 can be turned on to heat the bottom air inlet section of the sampling pipe 3, thereby effectively preventing the humid air from liquefying and producing condensate on the inner wall of the sampling pipe 3. However, if working in a humid environment, condensate may still accumulate inside the horizontal section of the sampling pipe 3. At this time, the condensate will gradually flow into the collection short pipe 4 at the inclined bottom wall of the sampling pipe 3, causing the buoyancy ball 43 to move upward under the action of buoyancy. At this time, the buoyancy ball 43 will stretch the tension spring 42 and push the driven block 54 to move upward. At this time, the driven block 54 will drive the slider 51 to slide upward inside the cross groove 5 through the connecting plate 53. At this time, the slider 51 will drive the sliding rod 55 to move upward. During this process, the drain trough 56 is still located below the collection short pipe 4, that is, the condensate still accumulates inside the collection short pipe 4 and cannot be discharged.

[0047] Meanwhile, the buoyancy ball 43 will push the push rod 45 upward via the connecting rod 44. As the bottom of the push rod 45 moves upward, it will push the horizontal connecting rod 61, which is rotatably connected at the top. Since the horizontal connecting rod 61 and the piston block 6 are fixedly connected and the piston block 6 slides inside the sampling pipe 3, the piston block 6 cannot move up and down but can only move left and right. At this time, the push rod 45, located on the lower left side of the piston block 6, will push the piston block 6 to the right. Therefore, the piston block 6 will slide in the horizontal section inside the sampling pipe 3. At this time, the piston block 6 pushes the condensate in the horizontal section inside the sampling pipe 3, causing the condensate to be pushed. The piston block 6 moves to the right vertical section of the sampling pipe 3, thus pushing out the condensate inside the sampling pipe 3. As the piston block 6 continues to move to the right, the buoyancy ball 43 also drives the sliding rod 55 to move upward. After the piston block 6 has cleared the condensate accumulated inside the sampling pipe 3, the sliding rod 55 also moves upward until it is at the top of the drain trough 56 inside the collecting short pipe 4. At this point, the inside and outside of the collecting short pipe 4 are connected through the drain trough 56, and the condensate accumulated at the bottom of the collecting short pipe 4 will be discharged downward through the drain trough 56, thus completing the treatment of the condensate inside the collecting short pipe 4 and the sampling pipe 3. After the condensate inside the collecting short pipe 4 is discharged, the buoyancy ball 43 is no longer buoyant, so it will move downward under the action of gravity and the rebound force of the tension spring 42, causing the sliding rod 55 to move downward and close the bottom of the collecting short pipe 4 again. At the same time, the push rod 45 pulls the piston block 6 to the left to the initial position to facilitate subsequent treatment of the condensate.

[0048] Simultaneously, the semi-circular piston block 6 cleans the condensate on the inner wall of the horizontal section of the sampling pipe 3. At this time, there may be water film remaining on the inner wall of the sampling pipe 3. Therefore, the operator needs to turn on the air pump to pump the gas into the interior of the connecting pipe 63 through the hose 65, and then discharge it through the exhaust slot at its bottom. Under the guidance of the guide plate 64, the gas is blown towards the inner wall of the sampling pipe 3. At this time, the sprayed gas can clean the water film remaining on the inner wall of the sampling pipe 3. At the same time, the connecting pipe 63 moves together with the piston block 6 to thoroughly clean the water film remaining on the inner wall of the sampling pipe 3, and discharge it through the vertical section on the right side of the sampling pipe 3 to avoid the residual water film affecting the detection accuracy of the gas.

[0049] When piston block 6 moves to process the condensate in the horizontal section of sampling pipe 3, piston block 6 will drive the rotating wheel 74 at the top to move. During the movement of rotating wheel 74, rotating ring 75 will rotate due to friction from the inner wall of sampling pipe 3. At this time, rotating ring 75 will drive rotating wheel 74 to rotate through friction. Rotating wheel 74 will then drive rotating rod 72 and active bevel gear 73 to rotate, causing active bevel gear 73 to drive meshing driven bevel gear 71 to rotate. When driven bevel gear 71 rotates, it will drive the valve stem of ball valve 7 to rotate, making the valve body open inside hose 65. Thus, the inside of hose 65 is in a connected state. Under the mutual constraint of limiting block one and limiting block two, the valve stem cannot continue to rotate after rotating 90 degrees, maintaining the connected state inside hose 65. At this time, rotating wheel 74 cannot continue to rotate. If rotating wheel 74 is unable to rotate due to external force, as piston block 6 continues to move, rotating ring 75 will overcome the friction between itself and rotating wheel 74 and rotate on the surface of rotating wheel 74.
