Description

Technical Field

[0001] This utility model relates to the field of flue gas sampling, specifically a flue gas sampling device. Background Technology

[0002] Flue gas sampling refers to the process of obtaining a certain amount of flue gas samples from flue gas emission sources generated during industrial production using specific equipment and methods. These samples are used for subsequent analysis and detection to understand the physical and chemical properties of the flue gas, such as its composition, concentration, temperature, and flow rate. The detection of flue gas composition is crucial in fields such as industrial production and environmental monitoring.

[0003] Traditional flue gas sampling devices have some shortcomings. For example, during the long-term absorption of flue gas, residual debris will be adsorbed on the inner wall of the sampling tube. These impurities will lead to inaccurate sampling results, which will affect subsequent analysis and processing. Therefore, a flue gas sampling device is proposed to solve the above problems.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the embodiments, by Figure 1-4 Provided is a flue gas sampling device, comprising a flue gas sampling body 1, a flue gas sampling tube 2 fixedly connected to the outside of the flue gas sampling body 1, a filter frame 3 fixedly connected to the inside of the flue gas sampling tube 2, a support frame 4 fixedly connected to the outside of the flue gas sampling tube 2, a lifting device 5 disposed inside the support frame 4, a fixing plate 6 slidably connected to the outside of the lifting device 5 and the support frame 4, a connecting rod 7 penetrating the filter frame 3 fixedly connected to the bottom of the fixing plate 6, a scraper 8 fixedly connected to the bottom of the connecting rod 7, and a collection frame 9 fixedly connected to the bottom of the flue gas sampling tube 2 by fasteners.

[0028] The lifting device 5 includes a motor 51 fixedly connected to the outside of the support frame 4. The output shaft of the motor 51 is fixedly connected to a threaded rod 52 rotatably connected to the inside of the support frame 4. The outside of the threaded rod 52 is connected to a transmission block 53 fixedly connected to the fixed plate 6.

[0029] In this embodiment, during actual use, the starting of the motor 51 will drive the threaded rod 52 to rotate, and at the same time, the transmission block 53 will move up and down under the action of the thread. During the up and down movement, the fixed plate 6 will move. Meanwhile, the outer side of the threaded rod 52 is provided with a dustproof telescopic protective sleeve, which can effectively prevent foreign objects such as dust, oil, and moisture from entering between the threaded rods and protect the threaded rods.

[0030] The support frame 4 has two sliding grooves that are symmetrically distributed on the left and right sides. The left and right sides of the fixing plate 6 are fixedly connected with sliders 10 that are slidably connected to the two sliding grooves respectively.

[0031] In this embodiment, during actual use, as the fixed plate 6 moves up and down, the slider 10 on the outside of the fixed plate 6 slides in the groove. The groove and the slider 10 remain in contact with each other, which restricts the movement direction of the transmission block 53 and provides support for the movement of the fixed plate 6.

[0032] The air inlet of the flue gas sampling body 1 is located on the side of the flue gas sampling tube 2, and the air inlet of the flue gas sampling body 1 is inclined upward.

[0033] In this embodiment, during actual use, the flue gas through the flue gas sampling tube 2 enters from the air inlet of the flue gas sampling body 1. At the same time, when the residue on the inner wall of the flue gas sampling tube 2 is scraped down and falls, it will not roll inward along the air inlet, preventing the residue from entering the interior of the flue gas sampling body 1 and affecting the judgment of the flue gas.

[0034] The scraper 8 is tapered, wider at the bottom and narrower at the top, and the bottom area of ​​the scraper 8 is equal to the internal cross-sectional area of ​​the flue gas sampling tube 2.

[0035] In this embodiment, during actual use, the conical scraper 8 has a relatively smooth surface. When the scraper 8 moves upward, it scrapes up and accumulates the residue on the inner wall of the flue gas sampling tube 2, which then slides to the edge of the scraper 8. When the scraper descends into the collection frame 9, it slides down into the collection frame 9 and is collected. The cleaning of the inner wall by the scraper 8 can extend its service life and reduce the interference of impurities on the detection results. After a long period of use, the flue gas sampling tube 2 still needs to be replaced regularly to make its detection results more accurate.

[0036] The collection frame 9 is fixedly connected to the flue gas sampling tube 2 by bolts and knobs, and the internal cross-sectional area of ​​the collection frame 9 is larger than the internal cross-sectional area of ​​the flue gas sampling tube 2.

[0037] In this embodiment, during actual use, when the scraper 8 extends into the interior of the collection frame 9, the wider space of the collection frame 9 will cause the residue and debris on the scraper 8 to slide off from the gaps. The bolt knobs are easy to manually tighten and disassemble, so that the collection frame 9 can be disassembled and removed.

[0038] Working principle:

[0039] During flue gas sampling operations, the operation of the flue gas sampling body 1 allows flue gas to be extracted through the flue gas sampling pipe 2. The flue gas sampling body 1 includes a suction pump and a gas collection bottle, which can store the flue gas before sampling and testing. During long-term flue gas absorption, residue will be adsorbed on the inner wall of the flue gas sampling pipe 2. The scraper 8 inside the flue gas sampling pipe 2 is normally located below the air inlet to isolate the flue gas sampling pipe 2 from the collection frame 9. When cleaning the inner wall of the flue gas sampling pipe 2, the filter frame 3 can initially intercept large impurities. Stop the operation of the flue gas sampling body, and the motor 51 can make the scraper 8 move up and down to scrape off the residue on the pipe wall of the flue gas sampling pipe 2. Then, the scraper 8 continues to descend, allowing the residue and debris to fall into the collection frame 9 for collection.
