The invention discloses a flue gas air-cooling heat recycling cooling system comprising a heat exchanging device communicating with a kiln flue gas chamber. The heat exchanging device comprises a heatexchanging tank, partition plates which are arranged in an up-down dislocation mode at intervals are distributed in the heat exchanging tank, the heat exchanging tank is partitioned by the partitionplates into a plurality of mutually-communicating cavities, each cavity is internally provided with a plurality of heat exchanging pipes arranged parallelly at intervals, and the heat exchanging pipescorresponding to the space between the adjacent cavities are connected through a bend; and a water cooling device is arranged behind the heat exchanging device and comprises a cylinder, a spirally-distributed cooling pipeline is arranged in the cylinder, a water outlet is formed in the bottom end of the cylinder, and the water outlet is connected to a self-cooling system through a pipeline. The flue gas air-cooling heat recycling cooling system adopts a mode of combining air cooling and water cooling, high-temperature flue gas at an inlet is cooled to the temperature of 180 DEG C or below, thus the flue gas conveniently enters a subsequent dust removal and wet desulfurization tower for desulfurization treatment, standardized discharge of the flue gas is ensured, and meanwhile, reasonableutilizing of heat energy is achieved.
Description
Technical field: [0001] The invention relates to the field of ceramic glaze production and processing, and mainly relates to a cooling system for air-cooling and heat-circulating utilization of flue gas. Background technique: [0002] In the existing ceramic glaze production process, the temperature of the flame outlet in the kiln melting furnace is very high, especially when it reaches about 1 hour, the temperature is close to 1100 degrees, while the refractory temperature in the melting furnace can only reach 1200-1400 degrees, so The flame hole and flue gas hole of the melting furnace will be replaced every hour to reduce the temperature at one end of the flame hole. A large amount of air must enter the flame hole to fully increase the temperature, but cold air will also reduce the temperature. Thereby reducing the utilization rate of heat. Moreover, after the flue gas discharged from the melting furnace passes through the flue gas chamber, its temperature is generally b...
