Problems solved by technology

Because the humidity of the flue gas in the flue is very high, it is not only easy to corrode the equipment, but also affects the service life of the device, making its maintenance efficiency high; at the same time, the water droplets in the flue gas are easy to adhere to the particles and adhere to the pipe wall of the sampling pipe above, resulting in a large error in the measurement of smoke and dust

Embodiment 1

[0036] refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 11 , a speed-adjustable sampling device of static pressure balance method, including a flue 1 and a sampling pipe 2 arranged in the flue 1, the end of the sampling pipe 2 away from the flue 1 is connected with a flue gas detection system, and the A smoke exhaust pipe 3 is connected to the bottom end, an L-shaped branch pipe 4 is arranged on the smoke exhaust pipe 3, and one end of the L-shaped branch pipe 4 away from the smoke exhaust pipe 3 is arranged in the sampling pipe 2, and a scraper ring 5 is arranged in the sampling pipe 2. The scraper ring 5 is provided with a disengagement component. The scraper ring 5 is movable against the inner wall of the sampling pipe 2 and the outer wall of the L-shaped branch pipe 4. The sampling pipe 2 is provided with a drive mechanism for driving the displacement of the scraper ring 5. A crushing mechanism for crushing lump dust is connected, and the c...

Embodiment 2

[0039] refer to image 3 , Figure 5 and Figure 7 , a speed-adjustable sampling device of a static pressure balance method, the same as that of Embodiment 1, and further, the scraping ring 5 includes a large ring 501 and a small ring 502, and one of the large ring 501 and the small ring 502 A connecting plate 503 is arranged between them, the large ring 501 is movable against the inner wall of the sampling tube 2 , and the small ring 502 is movable against the outer wall of the L-shaped branch pipe 4 .

[0040] Specifically, when the scraper ring 5 moves, it can scrape off the particles adhering to the inner wall of the sampling pipe 2 and the outer wall of the L-shaped branch pipe 4 at the same time, so that it can be easily absorbed by the smoke detection system and ensure the concentration of particles in the smoke. Test results.

Embodiment 3

[0042] refer to figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 9 and Figure 10 , a speed-adjustable sampling device of a static pressure balance method, the same as in Embodiment 2, further, the drive mechanism includes a rotating rod 6 that is rotatably connected in the sampling pipe 2, and the outer wall of the rotating rod 6 is connected with a rotating blade 601, The sampling pipe 2 is also provided with a guide block 7 for guiding the moving direction of the flue gas, the outer wall of the sampling pipe 2 is provided with a casing 8, the inner wall of the casing 8 is rotatably connected with a half gear 801, and the half gear 801 is fixedly connected with the rotating rod 6, A rack plate 802 is slidably connected to the inner wall of the housing 8, and the rack plate 802 is meshed with the half gear 801. A first elastic element 803 is arranged between the rack plate 802 and the inner wall of the housing 8, and a pull rope 804 is connected to the r...

Abstract

The invention discloses a speed-adjustable sampling device for a static pressure balance method, and belongs to the technical field of flue gas sampling detection. A speed-adjustable sampling device of a static pressure balance method comprises a flue and a sampling pipe arranged in the flue, the end, away from the flue, of the sampling pipe is connected with a smoke detection system, the bottom end of the flue is connected with a smoke exhaust pipeline, an L-shaped branch pipe is arranged on the smoke exhaust pipeline, and the end, away from the smoke exhaust pipeline, of the L-shaped branch pipe is arranged in the sampling pipe. A scraping ring is arranged in the sampling pipe, a separation assembly is arranged in the scraping ring, the scraping ring movably abuts against the inner wall of the sampling pipe and the outer wall of the L-shaped branch pipe, and a driving mechanism used for driving the scraping ring to move is arranged in the sampling pipe; according to the invention, sample gas collected in the sampling tube is heated, so that water vapor contained in the sample gas is removed, interference of moisture is eliminated, great errors caused by smoke measurement are effectively avoided, the accuracy of a detection result is improved, detection equipment can be prevented from being corroded, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of flue gas sampling and detection, in particular to a speed-adjustable sampling device of a static pressure balance method. Background technique [0002] The energy required in industrial production, such as electricity, heat, etc., mainly comes from the energy released by the combustion of fuel. Among them, the air pollution caused by the combustion of fuel is the most serious pollution caused by the emission of flue gas particulate matter from the chimney. The smoke and dust emitted from the combustion of these fuels is the main stationary pollution source that damages the quality of the atmospheric environment. It is necessary to purify the exhausted flue gas. The temperature of the purified flue gas drops, and it is easy to be cooled in the pipeline to form droplets with saturated humidity and low temperature, and it is easy to adhere to the pipe wall. [0003] The flue gas sampler is a common device ...
