The invention relates to the field of flue gas processing equipment, in particular to an industrial flue gas waste heat recycling system. The industrial flue gas waste heat recycling system comprisestwo water valves, a flue gas discharging structure, a storage structure, a limiting sleeve, a sealing structure and a waste heat utilization structure. The sealing structure used for sealing the cylinder structural storage structure is arranged at the center line position of the storage structure. The waste heat utilization structure used for storing cooling liquid is arranged in the storage structure. Two diagonally opposite corners of the water valves used for controlling water flow speed are symmetrically fixed to the storage structure and extend to the interior of the waste heat utilization structure. The flue gas discharging structure used for extending the contact time of flue gas and the cooling liquid is fixed to the storage structure and extends to the interior of the waste heat utilization structure. The limiting sleeve is arranged in the exterior of the storage structure in the peripheral direction. The using of the flue gas discharging structure slows down the discharging speed of the flue gas, increases the residence time of the flue gas, and meanwhile, the flue gas waste heat utilization efficiency and quality are improved by cooperating the using of the waste heat utilization structure and the flue gas to form convection.
Description
technical field [0001] The invention relates to the field of flue gas treatment equipment, in particular to an industrial flue gas waste heat recovery and utilization system. Background technique [0002] With the rapid development of society, people pay more and more attention to the environment. In the process of production and processing, flue gas needs to be treated by denitrification device. Denitrification is the process of removing nitrogen oxides from combustion flue gas. The mainstream process is divided into : SCR and SNCR, there are temperature limitations in the flue gas treatment process of these two processes, and it is necessary to heat the flue gas so as to improve the treatment quality of the flue gas. [0003] However, the traditional SNCR-SCR combined industrial flue gas denitrification device has low utilization efficiency of the waste heat in the flue gas during use, and it is inconvenient to repair and maintain the equipment. In view of this, the prese...
