Abstract
A module type flue gas heat exchanger with fluorine plastic pipes comprises a heat exchanger casing and a heat exchange pipe, wherein the upper end of the heat exchanger casing is provided with water inlets and water outlets, and the lower end of the heat exchanger casing is provided with a drain outlet. A water inlet end plate is detachably connected to the position of the water inlets and provided with water inlet holes, and a water outlet end plate is detachably connected to the position of the water outlets and provided with water outlet holes. The heat exchange pipes are U-shaped fluorine plastic heat exchange pipe bundles, water inlet ends of the fluorine plastic pipes in the fluorine plastic heat exchange pipe bundles are communicated with the water inlet holes, water outlet ends of the fluorine plastic pipes in the fluorine plastic heat exchange pipe bundles are communicated with the water outlet holes, and positioning nets are parallelly distributed in the heat exchanger casing from top to bottom at intervals. Module type design is adopted by the flue gas heat exchanger, equipment utilizing rate of the flue gas heat exchanger is greatly improved, the positioning nets are used by the flue gas heat exchanger at a fixed interval so as to fix the fluorine plastic pipes in the fluorine plastic heat exchange pipe bundles, and shaking deformation of the flexible fluorine plastic pipes caused by flowing impact of flue gas can be avoided.
Description
technical field [0001] The invention relates to a flue gas heat exchanger used in a thermal power plant boiler or other industrial boiler tail gas waste heat recovery system. Background technique [0002] On thermal power plant boilers or other industrial boilers, there is a tail gas waste heat recovery system for flue gas waste heat recovery. In the tail gas waste heat recovery system, a flue gas heat exchanger is generally installed at the entrance of the wet flue gas desulfurization tower. The flue gas heat exchanger recovers the waste heat of the flue gas. As the core equipment of the flue gas waste heat recovery system, the flue gas heat exchanger determines the performance of the waste heat recovery system. Flue gas waste heat recovery is of great significance, because flue gas waste heat recovery can not only utilize the waste heat of flue gas, but also reduce the temperature entering the flue gas desulfurization tower, reduce the evaporation of water in the desulfur...
