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 movable tunnel kiln flue gas collecting and purifying device, and relates to the technical field of movable tunnel kiln flue gas collection. The movable tunnel kiln flue gas collecting and purifying device comprises an outer ring track, an inner ring track arranged on the inner side of the outer ring track and a movable tunnel kiln arranged between the upper parts of the outer ring track and the inner ring track. An annular flue gas collecting pipe is arranged on the inner side of the inner ring track, and a desulfurization and denitrification tower is arranged in the center of the annular flue gas collecting pipe. An annular inserting plate fixedly connected with the bottom face of a rotating ring plate is rotationally arranged in a mounting opening. A blocking mechanism used for closing a flue gas exhaust pipe is arranged in a communicating opening. A removing mechanism for scraping impurities at the bottom of the annular flue gas collecting pipe is arranged on the other side of the bottom surface of the annular inserting plate. By means of the blocking mechanism, the flue gas exhaust pipe can be closed conveniently when the temperature of the movable tunnel kiln rises, and the temperature raising efficiency of the movable tunnel kiln is improved; and through cooperation of the rotating ring plate and the removing mechanism, impurities deposited in the annular flue gas collecting pipe can be conveniently scraped, and the cleaning efficiency of the impurities deposited in the annular flue gas collecting pipe can be conveniently improved.
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...
