Methanation device of low -grade waste heat of effective recycling

The utility model relates to a methanation device of low -grade waste heat of effective recycling, organize, evaporate overheated subassembly, waste heat recoverer, pre -heater, knockout drum subassembly, circulation lime set pump, cooler, flow control valve and accuse temperature component including smart desulfurization reactor, multistage methanator. The utility model discloses a setting up theoverheated subassembly of evaporation on final stage methanator's outlet pipe way, utilizing the low -grade waste heat of final stage methanator export to make the feed gas after the water injectionbecome overheated feed gas, through this mode, improved the low -grade surplus pick up the heat of methanation reaction final stage on the one hand and rateed, water injection rate what on the other hand passes through, but effective control methanation reaction is exothermic, makes easily control of methanation reaction. 本实用新型涉及种有效回收低品位余热的甲烷化装置，包括精脱硫反应器、多级甲烷化反应器组、蒸发过热组件、余热回收器、预热器、分离罐组件、循环凝液泵、冷却器、流量调节阀和控温元件。本实用新型通过在末级甲烷化反应
