Description

Technical Field

[0001] The utility model relates to the technical field of waste gas sampling, in particular to a waste gas sampling device. Background Art

[0002] Today, with the increasing attention to environmental protection, the monitoring and management of waste gas emissions have become an indispensable part of the enterprise production process. However, traditional waste gas sampling devices often have problems such as uneven sampling, low detection accuracy, high maintenance costs, and inconvenient data management, making it difficult to meet the high standards of modern environmental protection supervision.

[0003] First of all, the waste gas often has a high speed and uneven distribution during the flow process, which makes it difficult for traditional sampling devices to accurately capture representative waste gas samples, thus affecting the accuracy of subsequent detections. In addition, there are various types of particulate matter and pollutants in the waste gas, and how to effectively achieve their physical separation and collection is also a major challenge faced by traditional devices.

[0004] Secondly, during the sampling process, the cleaning and maintenance of the equipment are crucial for ensuring the sampling accuracy and extending the service life. However, traditional devices often lack an effective automatic cleaning mechanism, resulting in key components such as air-permeable belts being easily blocked or worn, increasing the user's usage cost and maintenance difficulty.

[0005] Furthermore, with the continuous strengthening of environmental protection supervision, higher requirements are put forward for the real-time and accuracy of waste gas emission data. However, traditional devices often rely on manual recording and data transmission, which is not only inefficient but also error-prone, making it difficult to meet the management needs of modern enterprises.

[0008] Optionally, the first detection section is a round shuttle-shaped structure that is narrow at both ends and wide in the middle.

[0009] Optionally, the left and right ends of the second detection section are respectively communicated with the corresponding sampling pipe and exhaust pipe through variable diameter connection ends;

[0010] A motor is fixedly installed at the upper end position of the outer side wall of one end of the second detection section. Rotating rollers are respectively rotatably installed at the upper and lower ends of the middle part of the second detection section. An air-permeable belt is rotatably connected between the upper and lower rotating rollers in the inner cavity of the second detection section. One end of the rotating roller at the upper end is fixedly connected to the rotating shaft of the motor;

[0011] A vertical window is inlaid on the outer wall of the second detection section below the motor. A sedimentation collection bin extends downward from the lower end of the middle part of the second detection section. A sewage pipe extends downward from the lower end of the sedimentation collection bin. A second detection end is obliquely inserted into the sewage pipe, and the second detection end is electrically connected to the control box;

[0014] Optionally, an exhaust fan is provided in the exhaust pipe, and the exhaust fan sucks the air in the sampling pipe and outputs it from the intake pipe end through the first detection section and the second detection section from the exhaust pipe.

[0015] The present utility model provides an exhaust gas sampling device, which has the following beneficial effects:

[0016] First, the circular spindle-shaped design of the first detection section ingeniously achieves the gradual deceleration and uniform distribution of the exhaust gas during the flow process, laying a solid foundation for subsequent precise detection.

[0038] The present utility model provides an exhaust gas sampling device, including: a sampling tube 1, a first detection section 2, an air inlet pipe 3, a retention detection tube 4, a second detection section 5, a hanger 6, a control box 7, and an air outlet pipe 8; one end of the sampling tube 1 is connected to the first detection section 2, and the other end of the first detection section 2 is connected to the air inlet pipe 3; the other end of the sampling tube 1 is connected to the second detection section 5 in a "V" shape, and the other end of the second detection section 5 is connected to the air outlet pipe 8; a control box 7 is fixedly arranged at the upper end of the second detection section 5; a hanger 6 is horizontally and fixedly connected between the upper ends of the first detection section 2 and the second detection section 5, and the hanger 6 is used for fixedly connecting to an external wall; the lower end of the middle part of the first detection section 2 is fixedly connected to the retention detection tube 4; the lower end of the inner cavity of the retention detection tube 4 is connected to the first detection end 401, the first detection end 401 is electrically connected to the control box 7, and a wireless transmission module is built in the control box 7.

[0039] Among them, the first detection section 2 has a round shuttle-like structure that is narrow at both ends and wide in the middle.

[0040] Among them, the left and right ends of the second detection section 5 are respectively connected to the corresponding sampling pipe 1 and the air outlet pipe 8 through variable-diameter connection ends 501;

[0041] At the upper position of the outer side wall of one end of the second detection section 5, a motor 505 is fixedly installed. Rotating rollers 507 are respectively rotatably installed at the upper and lower ends of the middle part of the second detection section 5. An air-permeable belt 508 is rotatably connected between the two rotating rollers 507 in the inner cavity of the second detection section 5. One end of the rotating roller 507 at the upper end is fixedly connected to the rotating shaft of the motor 505;

[0042] A vertical window 502 is inlaid on the outer wall of the second detection section 5 below the motor 505. A sedimentation collection bin 503 extends downward from the lower end of the middle part of the second detection section 5. A sewage discharge pipe 504 is provided downward at the lower end of the sedimentation collection bin 503. A second detection end 5041 is obliquely inserted on the sewage discharge pipe 504, and the second detection end 5041 is electrically connected to the control box 7;

[0043] A liquid supplement pipe 506 is provided upward on the side wall of one end of the second detection section 5 away from the window 502. The water level in the second detection section 5 is replenished to the root position of the variable-diameter connection end 501;

[0044] Scrapers 509 are provided at the positions on the left and right sides of the front and rear side walls of the rotating roller 507 located below in the inner cavity of the second detection section 5. The air-permeable belt 508 rotates clockwise, and the two scrapers 509 are respectively tangent to the air-permeable belt 508.

[0045] Embodiment 2, on the basis of Embodiment 1, an exhaust fan 801 is provided in the air outlet pipe 8. The exhaust fan 801 sucks the air in the sampling pipe 1 and outputs it from the air outlet pipe 8 after passing through the first detection section 2 and the second detection section 5 from one end of the air inlet pipe 3.

[0046] The working principle of this embodiment:

[0047] The device introduces the waste gas to be detected through the sampling pipe 1, and the waste gas then enters the first detection section 2. The round shuttle-like design of the first detection section 2 helps the waste gas to gradually decelerate and be evenly distributed during the flow process, facilitating subsequent precise detection.

[0048] After the exhaust gas passes through the first detection section 2, it continues to flow towards the intake pipe 3 and is then guided to the second detection section 5. The second detection section 5 is designed in a "V" shape and is equipped with a breathable belt 508 system driven by a motor 505 inside. This system supports the breathable belt 508 through a rotating roller 507, enabling it to rotate clockwise. When the exhaust gas passes through the breathable belt 508, the particulate matter and pollutants in it will deposit on the breathable belt under the action of gravity and be gradually carried downward as the breathable belt rotates.

[0049] At the lower middle part of the second detection section 5, there is a sedimentation collection bin 503 for collecting the particulate matter that falls from the breathable belt 508. These particulate matter will eventually be discharged through the sewage pipe 504, and the second detection end 5041 on the sewage pipe 504 is used to monitor the particulate matter absorbed in the water, so as to achieve the purpose of accurately analyzing the content in the exhaust gas.

[0050] In order to maintain the humidity and cleanliness inside the second detection section 5, the device is also equipped with a liquid replenishment pipe 506, allowing users to supplement water according to needs. The water replenishment level is controlled at the root position of the variable-diameter connection end 501 to ensure that the breathable belt 508 can be fully wetted and effectively capture the pollutants in the exhaust gas.

[0051] In addition, there are scrapers 509 inside the second detection section 5. They are tangent to the breathable belt 508 and continuously scrape the residues on its surface as the breathable belt rotates, maintaining the cleanliness and air permeability of the breathable belt.

[0052] During the entire sampling process, the exhaust gas will pass through the first detection section 2 and the second detection section 5 in sequence and undergo preliminary detection and purification treatment therein. Finally, the treated exhaust gas is discharged through the outlet pipe 8, and the exhaust fan 801 in the outlet pipe 8 is responsible for providing the necessary power to ensure that the exhaust gas can smoothly pass through the entire device.

[0053] It should be noted that the device is also equipped with a control box 7, which is built-in with a wireless transmission module. This enables the device to wirelessly transmit the detection data to a remote monitoring center or the user's intelligent terminal in real time, facilitating the user to keep track of the exhaust gas emission situation and the operating status of the device at any time. At the same time, the control box 7 may also contain other control elements and sensors for realizing the automatic control and accurate monitoring of the entire sampling process.
