The utility model discloses a flow equalizing device for flue gas at an outlet of a desulfurization wastewater drying tower and raw flue gas, and relates to the technical field of zero emission of desulfurization wastewater of a coal-fired unit. The device comprises a flow-equalizing distribution pipe, flow-equalizing distribution branch pipes, an air preheater and a drying tower, the flow equalizing distribution pipe is located in an air preheater outlet flue of the air preheater, and a plurality of flow equalizing distribution branch pipes are arranged on the flow equalizing distribution pipe at intervals. An air preheater outlet flue is connected with a plurality of air preheater outlet flue branch pipes, and a drying tower outlet flue of the drying tower is inserted into the air preheater outlet flue and connected with the right end of the flow equalizing distribution pipe. The flue work amount in a conventional scheme can be effectively reduced, the problems of contamination and blockage of a heat exchange pipe of a low-temperature economizer at an inlet of a dust remover due to uneven diversion of wet flue gas of desulfurization waste water are solved, the flue gas waste heat utilization effect is improved, and the economical efficiency of a unit is improved.

This utility model discloses a waste heat treatment device for high-temperature flue gas, including a flue gas channel connected to a desulfurization tower. A wastewater collection tank is connected below the desulfurization tower, and the wastewater collection tank is connected to a wastewater pretreatment tank. The wastewater pretreatment tank is connected to a wastewater treatment tank. A heat exchange section is provided on the flue gas channel, and a heat exchange chamber is provided outside the heat exchange section. A steam heat exchange pipe is provided on the wastewater treatment tank, including an inlet end and an outlet end. The outlet end is connected to the heat exchange chamber, and the heat exchange chamber is connected to the inlet end. A spray structure is provided inside the desulfurization tower, connected to a slurry tank, which is connected to a slurry preparation tank. A heat exchange pipe is also provided inside the flue gas channel, with one end connected to a water source and the other end connected to the slurry preparation tank. In this utility model, the flue gas undergoes two cooling and heat exchange cycles before entering the desulfurization tower for desulfurization, improving desulfurization efficiency and effect. Simultaneously, waste heat is recovered and utilized for heating wastewater and preheating the desulfurization slurry, improving waste heat utilization efficiency.
