Description
Technical Field
[0001] This utility model relates to the field of flue gas outlet technology, and in particular to a flue gas outlet for a reverberatory furnace. Background Technology
[0002] The flue is an indispensable channel for the discharge of high-temperature flue gas during the operation of a reverberatory furnace. During the continuous operation of the reverberatory furnace, the intense combustion of fuel generates a large amount of high-temperature flue gas. Without the flue to provide a smooth discharge path, the high-temperature flue gas will continue to accumulate in the furnace, accompanied by high pressure. If blockage or unreasonable design leads to obstruction of flue gas discharge, the pressure inside the furnace will rise sharply, causing serious safety accidents and even damaging the furnace structure. The design of the flue ensures that the flue gas is discharged stably and efficiently, maintaining a suitable gas pressure state inside the furnace, ensuring the safe and stable operation of the reverberatory furnace, and allowing the smelting and heating processes to proceed smoothly.
[0003] In traditional flue gas outlet designs, the inability to control airflow leads to significant resistance to flue gas emission, hindering smooth discharge. This increases furnace pressure, causing backflow of flue gas, impacting production operations and the environment. The temperature at the flue gas outlet of a reverberatory furnace is very high, and materials exposed to prolonged high temperatures are prone to softening, deformation, or even melting. This not only affects the normal function of the flue gas outlet but can also cause safety accidents. Furthermore, it reduces the thermal insulation performance of the flue gas outlet material, increases energy consumption, and raises the temperature around the outlet, affecting the safety of operators and the normal operation of surrounding equipment.

[0039] Working principle: The flue gas first enters the metal barrel 1. The rotating fan 10 accelerates the flow of flue gas in the metal barrel 1. The microporous filter screen 3 9 at the bottom of the inner side of the metal barrel 1 intercepts and filters larger particulate impurities in the flue gas. The flue gas passing through the microporous filter screen 3 9 flows quickly to the transmission pipe 5. The transmission pipe 5 guides the treated flue gas to the cooling pipe 6. The cooling pipe 6 uses the internal cooling medium to exchange heat with the high temperature flue gas, which quickly reduces the temperature of the flue gas. The heat insulation cover 7 at the top of the cooling pipe 6 prevents the heat of the cooled flue gas from dissipating to the surrounding environment, stabilizing the working environment of the purification device 2.
[0040] The transmission channel 201 introduces the cooled flue gas from the heat insulation cover 7 into the purification tank 202. The microporous filter 203 inside the transmission channel 201 performs initial fine filtration of the flue gas, intercepting tiny particulate impurities. The activated carbon 204 at the bottom of the inner side of the purification tank 202 removes harmful gases, odor molecules, and some fine particulate pollutants from the flue gas through adsorption. The microporous filter 205 at the top of the inner side of the purification tank 202 performs a second filtration, intercepting particles and other extremely fine impurities that may be carried out with the airflow, ensuring that the discharged purified flue gas is pure and free of solid impurities. The fixing rod 206 and the threaded rod 207 stably support the activated carbon 204 and the microporous filter 205, facilitating later inspection, replacement, and maintenance.
