Description

Technical Field

[0001] The utility model relates to the technical field of soot emission, and more specifically, the utility model relates to a soot ultra-low emission pipe. Background Art

[0002] A soot ultra-low emission pipe is a kind of pipe used for discharging flue gas formed in the chemical production process. In order to ensure the efficiency of soot purification, a filtering device is usually arranged inside the discharge pipe. For example, a soot ultra-low emission pipe disclosed in the patent with the prior art publication number CN209791125U. By pulling the limit rod, the limit rod is withdrawn from the limit hole. At this time, the reset elastic member is stretched. Then, the second dust filtering plate is slid to adjust the area of the overlapping part between the second dust filtering plate and the first dust filtering plate, so as to adjust the dust filtering effect of the discharge pipe. After the second dust filtering plate is adjusted, the limit rod is released, and the reset elastic member restores its deformation, so that the limit rod automatically slides towards the limit hole and finally is inserted into the corresponding limit hole to complete the locking of the second dust filtering plate.

[0003] When the above device is in use, the dust filtering effect of the discharge pipe can be adjusted so that the overall filtering effect of the discharge pipe can be adjusted to the required degree, thereby effectively filtering the flue gas and ensuring the filtering effect. However, some dust is likely to accumulate on the surface of the filter screen. When cleaning, the filter screen needs to be pulled out, but the pipe will scrape off the dust on the surface of the filter screen, thus affecting the filtering effect of the filtering part.
