Description

Technical Field

[0001] The utility model relates to the technical field of high-efficiency sealed portable flue gas sampling, and particularly relates to a high-efficiency sealed portable flue gas sampling device. Background Art

[0002] With the continuous improvement of the global attention to environmental protection, the monitoring requirements for emissions from various pollution sources are becoming increasingly strict. As an important pollutant generated during industrial production, energy utilization and other processes, the accurate sampling and analysis of flue gas are crucial for evaluating environmental impacts and formulating emission reduction strategies. Countries and regions have successively introduced more stringent environmental protection laws and emission standards, requiring more frequent and accurate monitoring of flue gas emissions, which has promoted continuous innovation in related technologies to meet regulatory requirements.

[0003] Flue gas sampling mainly involves collecting the discharged flue gas and then detecting the components and particulate matter in the flue gas through equipment. Traditional flue gas detection mainly uses a manually-held flue gas sampling device to sample and collect flue gas. This method has a large labor intensity. Among them, the flue gas sampling device cannot be adjusted in height. The heat in the flue gas will generate water droplets when it encounters cold. The presence of water droplets in the sampling device will affect the use effect of the flue gas sampling device. For this reason, we propose an intelligent flue gas sampling device.

[0004] An existing patent (publication number: CN214224677U) is an intelligent flue gas sampling device. By fixedly connecting a connecting cylinder to the surface of the base, a connecting rod is arranged inside the connecting cylinder, a first round hole is opened on the outer wall of the connecting cylinder, and a threaded rod passes through the first round hole. When adjusting the connecting rod and the connecting cylinder, first, the user manually adjusts the connecting rod to a suitable height, and then rotates the rotating shaft. The rotating shaft will drive the threaded rod to move inside the first round hole. One end of the threaded rod is rotatably connected with an abutting plate, and the abutting plate will clamp and fix the connecting rod inside the connecting cylinder. After the abutting plate abuts and fixes with the connecting rod, then rotate the fixing ring screwed on the threaded rod to make the fixing ring abut against the outer wall of the connecting cylinder. Since the arc groove opened on the abutting plate has the same radian as the outer wall of the connecting rod, it ensures that the abutting plate and the connecting rod are more tightly fastened. Finally, a water collecting tank is arranged inside the collecting box, and a condensation water column is arranged at the bottom inside the water collecting tank. After the flue gas containing heat enters the water collecting tank through the air inlet pipe and contacts the condensation water column, the heat generates water vapor that will condense into water droplets, and the water droplets flow along the condensation water column to the water outlet pipe arranged at the bottom of the water collecting tank and are discharged, solving the problem that the heat in the traditional flue gas sampling device will generate water droplets when it encounters cold, and the presence of water droplets in the sampling device will affect the use effect of the flue gas sampling device.

[0005] In view of the above problems, existing patents have provided solutions. Existing flue gas sampling devices mainly insert a sampling probe into the flue gas discharge pipe, and then use a vacuum pump to transport the sampled flue gas into the sampling container for storage, so as to facilitate subsequent analysis in the laboratory. However, when the sampling probe is inserted into the flue gas discharge pipe, its installation is not firm, resulting in the sampling probe shaking or shifting in the pipe, making the sampling position unstable, and the collected flue gas sample may be taken from the part with a lower edge concentration, thus affecting the accuracy of subsequent analysis results.

[0006] Therefore, an efficient sealed portable flue gas sampling device is proposed. Utility Model Content

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figure 1-6 , the present utility model provides a technical solution:

[0029] An efficient sealing type portable flue gas sampling device, including a sampling box 1, a placement groove 2 is opened inside the sampling box 1, an air extraction pump 3 is fixedly connected inside the placement groove 2, a filter assembly 4 is fixedly connected to the front side of the sampling box 1, and the filter assembly 4 includes a filter box 401 fixedly connected to the front side of the sampling box 1, and a sampling assembly 5 is arranged on the front side of the filter box 401;

[0030] The sampling assembly 5 includes a connecting hose 501 fixedly connected to the front side of the intake pipe 405. A flue gas sampling pipe 502 is bolted to the top of the connecting hose 501. A sampling head 503 is connected to the top of the flue gas sampling pipe 502. A support plate 504 is bolted to the outside of the flue gas sampling pipe 502. A groove 505 is formed inside the support plate 504. An electric telescopic rod 506 is bolted inside the groove 505. A top plate 507 is bolted to the output end of the electric telescopic rod 506. An auxiliary telescopic rod 508 is fixedly connected to the top of the support plate 504. The output end of the auxiliary telescopic rod 508 is bolted to the outside of the top plate 507.

[0031] In this embodiment: The sampling head 503 at the top of the flue gas sampling pipe 502 is placed at the position of the flue gas to be sampled. Then, the electric telescopic rod 506 is started, and the output end of the electric telescopic rod 506 drives the top plate 507 to move, thereby assisting in fixing the positions of the flue gas sampling pipe 502 and the sampling head 503. Then, the auxiliary telescopic rod 508 expands and contracts as the top plate 507 moves, playing a role in auxiliary support and stability. Then, the flue gas enters the flue gas sampling pipe 502 through the sampling head 503, and then enters the filtering assembly 4 through the connecting hose 501. After sampling, the output end of the electric telescopic rod 506 drives the top plate 507 to move, releasing the fixation of the flue gas sampling pipe 502. Compared with the existing flue gas sampling device, the position adjustment of the sampling head 503 is more stable and accurate, ensuring that a representative flue gas sample can be accurately collected.

[0032] Specifically, as Figure 3 、 Figure 4 、 Figure 5 shown, an air outlet 402 is formed at the rear side of the filtering box 401. An outlet pipe 403 is bolted inside the air outlet 402. The rear side of the outlet pipe 403 is bolted to the intake end of the air extraction pump 3. An air inlet 404 is formed at the front side of the filtering box 401. An intake pipe 405 is bolted inside the air inlet 404.

[0033] Specifically, as Figure 3 、 Figure 4 、 Figure 5 shown, a filter net plate 406 is slidably connected to the top of the filtering box 401. A pull handle 407 is bolted to the top of the filter net plate 406.

[0034] Specifically, as Figure 3 、 Figure 4 、 Figure 5 shown, a sealing sleeve 408 is sleeved on the outside of the top of the filter net plate 406. The sealing sleeve 408 is embedded in the top of the filtering box 401. The sealing sleeve 408 is made of rubber material.

[0035] In this embodiment: The flue gas enters the filtration box 401 through the sampling component 5. First, it enters the interior of the filtration box 401 through the intake pipe 405. Then, the flue gas passes through the filtration of the filter mesh plate 406 in the filtration box 401 to remove impurities and particulate matter in the flue gas. Next, the filtered flue gas enters the air extraction pump 3 through the outlet pipe 403 of the air outlet 402, preparing for subsequent sampling processing. Then, the sealing sleeve 408 can effectively ensure the tightness of the filtration box 401 when the flue gas is filtered. After that, after the filtration is completed, the filter mesh plate 406 is taken out through the pull handle 407 for easy cleaning and replacement. Compared with the existing flue gas sampling device, it can effectively remove impurities and particulate matter in the flue gas, improving the accuracy and reliability of flue gas sampling.

[0036] Specifically, as Figure 1 , Figure 4 , Figure 5 shown, the air extraction end of the air extraction pump 3 is fixedly connected with a delivery pipe 6, and an air capacitance storage box 7 is bolted to the front side of the sampling box 1. The top of the air capacitance storage box 7 is communicated with the bottom of the delivery pipe 6.

[0037] Specifically, as Figure 3 , Figure 6 shown, sliding grooves 8 are respectively formed on both sides of the top of the filtration box 401. A sliding block 9 is slidably connected inside the sliding groove 8, and the inner side of the sliding block 9 is fixedly connected with the outer side of the filter mesh plate 406.

[0038] In this embodiment: By setting the delivery pipe 6 and the air capacitance storage box 7, it is convenient to store the collected flue gas to ensure that the flue gas can be safely and stably stored, facilitating subsequent analysis and detection. By setting the sliding groove 8 and the sliding block 9, the replacement and cleaning of the filter mesh plate 406 are made more convenient and fast, improving the operation efficiency. At the same time, it helps to ensure the stability of the filter mesh plate 406 in the filtration box 401 to ensure the filtration effect.

[0039] Specifically, as Figure 1 , Figure 5 shown, a rubber block 10 is fixedly connected to the front side of the sampling box 1, and a clamping groove 11 is formed inside the rubber block 10.

[0040] Specifically, as Figure 1 , Figure 4 , Figure 5 shown, a pull rod 12 is fixedly connected to the top of the sampling box 1, and an anti-slip sleeve 13 is sleeved on the outer side of the pull rod 12. The anti-slip sleeve 13 is made of rubber.

[0041] In this embodiment: By providing the rubber block 10 and the card slot 11, the flue gas sampling pipe 502 can be snapped into the card slot 11, thereby improving the fixing stability of the flue gas sampling pipe 502 after storage. At the same time, the rubber block 10 has a certain buffering and protective effect, which can reduce the impact of external shocks on the flue gas sampling pipe 502. By providing the pull rod 12 and the anti-slip sleeve 13, the sampling device is made more portable, improving the convenience of use. The design of the anti-slip sleeve 13 enhances the safety of operation and reduces damage or accidents caused by slipping.

[0042] Working principle: During the use of the highly sealed portable flue gas sampling device, the sampling head 503 at the top of the flue gas sampling pipe 502 is placed at the position of the flue gas to be sampled. Then, the electric telescopic rod 506 is activated, and the output end of the electric telescopic rod 506 drives the top plate 507 to move, thereby assisting in fixing the positions of the flue gas sampling pipe 502 and the sampling head 503. Then, the auxiliary telescopic rod 508 expands and contracts as the top plate 507 moves, playing a role in auxiliary support and stability. Then, the flue gas enters the flue gas sampling pipe 502 through the sampling head 503, and then enters the filter box 401 through the connecting hose 501. Then, the flue gas is filtered by the filter mesh plate 406 in the filter box 401. Then, the sealing sleeve 408 can effectively ensure the tightness of the filter box 401 when the flue gas is filtered, removing impurities and particulate matter in the flue gas. Then, it enters the air pump 3 through the outlet pipe 403 of the air outlet 402. The air pump 3 extracts the filtered flue gas and transports it to the air storage tank 7 through the delivery pipe 6 for storage. Then, after the sampling is completed, the output end of the electric telescopic rod 506 drives the top plate 507 to move, releasing the fixation of the flue gas sampling pipe 502, and snapping the flue gas sampling pipe 502 into the card slot 11, thereby improving the fixing stability of the flue gas sampling pipe 502 after storage. This solves the problem that the existing flue gas sampling device mainly inserts the sampling probe into the flue gas discharge pipe, and then transports the sampled flue gas to the inside of the sampling container through a vacuum pump for storage, so as to be taken back to the laboratory for analysis later. However, when the sampling probe is inserted into the flue gas discharge pipe, its installation is not firm, resulting in the sampling probe shaking or shifting in the pipe, making the sampling position unstable, and the collected flue gas sample may collect the part with a lower concentration at the edge, thus affecting the accuracy of the subsequent analysis results.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
