烟气余热回收系统
摘要：
本发明涉及锅炉的辅助装置技术领域，尤其是涉及一种烟气余热回收系统。所述烟气余热回收系统包括烟气冷却器、脱硫塔、烟囱、余热使用装置和排烟温度控制系统，所述烟气冷却器包括换热箱体和换热管体，所述换热管体设置于所述换热箱体的内部，所述换热管体用于冷却所述换热箱体中的烟气；所述换热箱体、所述脱硫塔和所述烟囱依次连通；所述换热管体与所述余热使用装置相连通；所述排烟温度控制系统用于控制所述换热箱体排出的烟气的温度。本发明所提供的烟气余热系统，不仅节约了水资源，减少了污水的排放，降低了烟气余热资源的损失，而且提高了烟气余热资源的利用效率，能够有效促进环境与经济的协调发展。
摘要（英）：

The invention relates to the technical field of auxiliary devices of boilers, in particular to a flue gas waste heat recovery system. The flue gas waste heat recovery system comprises a flue gas cooler, a desulfurizing tower, a chimney, a waste heat utilization device and a smoke exhaust temperature control system. The flue gas cooler comprises a heat exchange box body and a heat exchange pipe body. The heat exchange pipe body is arranged in the heat exchange box body and used for cooling flue gas in the heat exchange box body. The heat exchange box body, the desulfurizing tower and the chimney are sequentially communicated. The heat exchange pipe body communicates with the waste heat utilization device. The smoke exhaust temperature control system is used for controlling the temperature of the flue gas discharged out of the heat exchange box body. By means of the flue gas waste heat recovery system, water resources are saved, the sewage discharge is reduced, losses of flue gas waste heat resources are reduced, the utilization efficiency of the flue gas waste heat resources is improved, and the coordinated development of environment and economy can be effectively promoted.
