Problems solved by technology
[0003] When the existing flue gas collection and purification device for the mobile tunnel kiln is in use, it is not convenient to close the exhaust pipe of the mobile tunnel kiln when the temperature of the mobile tunnel kiln is raised, causing the internal flue gas to carry heat and further In the collection and purification device, the temperature rise rate of the mobile tunnel kiln is slow, and when the mobile tunnel kiln is moving, the impurities deposited inside the smoke collection pipe cannot be scraped up, which makes it difficult to remove the impurities attached to the inner wall of the smoke collection pipe in the later stage ; Therefore, the above problems need to be improved

The invention discloses a mobile tunnel kiln flue gas collection and purification device, which relates to the technical field of mobile tunnel kiln flue gas collection. The mobile tunnel kiln between the upper part of the ring track, the inner side of the inner ring track is equipped with a ring-shaped smoke collection pipe, and the center of the ring-shaped smoke collection pipe is equipped with a desulfurization and denitrification tower; the installation port is rotated and installed with a ring plate that is fixed to the bottom surface of the rotating ring plate The connecting port is provided with a blocking mechanism for closing the smoke exhaust pipe; the other side of the bottom surface of the annular insert plate is provided with a cleaning mechanism for scraping impurities at the bottom of the annular smoke collecting pipe; When the kiln heats up, the smoke exhaust pipe is closed to improve the heating efficiency of the mobile tunnel kiln; through the cooperation of the moving ring plate and the cleaning mechanism, it is convenient to scrape up the impurities deposited inside the ring smoke collection pipe, which is convenient to improve the efficiency of the ring collection Cleaning efficiency of impurities deposited inside the smoke tube.
Description
technical field [0001] The invention relates to the technical field of mobile tunnel kiln flue gas collection, in particular to a mobile tunnel kiln flue gas collection and purification device. Background technique [0002] At present, there are a large number of domestic brick and tile kilns and various types. During the process of firing shale bricks or refractory bricks and other products in coal-fired tunnel kilns, the main pollutants discharged are smoke, SO2, NOx and CO. If they are not collected and dedusted and purified , is directly discharged into the atmosphere, and has a general destructive effect on human health, plant growth, and ambient air; [0003] When the existing flue gas collection and purification device for the mobile tunnel kiln is in use, it is not convenient to close the exhaust pipe of the mobile tunnel kiln when the temperature of the mobile tunnel kiln is raised, causing the internal flue gas to carry heat and further In the collection and purif...
