The present invention discloses a glass furnace flue gas cooling and heat-exchanging device. The device comprises a mounting rack, a flue gas entrance and a flue gas exit are disposed in a perpendicular direction of the mounting rack, and an air entrance and an air exit are disposed in a horizontal direction of the mounting rack. A heat exchange zone is arranged in the center of the flue gas entrance, the flue gas exit, the air entrance and the air exit and includes a group of vertically-arranged wide-runner heat exchange plate pipes which are spaced from each other. Horizontal entrances of the wide-runner heat exchange plate pipes are connected in parallel with each other and then connected with the air entrance, and horizontal exits of the wide-runner heat exchange plate pipes are connected in parallel with each other and then connected with the air exit. The flue gas entrance is communicated with a gap above the wide-runner heat exchange plate pipes while the flue gas exit is communicated with a gap below the wide-runner heat exchange plate pipes. Flue gas and air exchange heat with each other in a crossed manner, so the heat exchange efficiency is high. The wide-runner heat exchange plate pipes are resistant to corrosion and easy to clean and thus can help prolong the service life of equipment.
Description
technical field [0001] The invention relates to the technical field of glass kiln waste heat utilization, in particular to a glass kiln flue gas cooling and heat exchange device. Background technique [0002] At present, the comprehensive process of glass kiln waste heat utilization and flue gas treatment integration is: high-temperature flue gas first enters the high-temperature heat exchange section of the waste heat boiler, then leaves the waste heat boiler to remove dust and denitrification system, and the flue gas after denitrification returns to the waste heat boiler , after passing through the low-temperature heat exchange section of the waste heat boiler, it enters the desulfurization and dust removal system after leaving the waste heat boiler. [0003] Since the glass kiln flue gas contains a large amount of sticky dust, the waste heat boiler must be shut down after a period of operation, and the dust should be manually cleaned off-line. This makes it impossible to...
