Description

MTBE production methanol recovery and wastewater recycling device Technical Field The utility model relates to the technical field of MTBE production, in particular to a methanol recovery and wastewater recycling device for MTBE production. Background In the production process of MTBE (methyl tert-butyl ether), methanol recovery and wastewater treatment are key links for guaranteeing resource recycling and reducing production cost, MTBE is used as an important gasoline additive, the production process of the MTBE relates to recycling of a large amount of methanol raw materials, and if methanol-containing wastewater generated after reaction is directly discharged, not only is resource waste caused, but also the risk of environmental pollution is brought. The existing distillation equipment has the advantages that most of distillation boxes adopt a horizontal heating design, so that the temperature distribution of wastewater in the boxes is uneven, the wastewater at the bottom is easy to overheat and vaporize due to direct heating, the temperature of the water at the upper part is slowly raised due to heat conduction hysteresis, a temperature gradient is formed, the heat exchange defect not only prolongs the distillation period and reduces the recovery rate of methanol, but also increases the energy consumption cost, and particularly when the high-concentration methanol wastewater is treated, the scaling phenomenon is easy to be caused due to local overheating, so that the service life of the equipment is further influenced. The technical scheme disclosed in the patent document is that a methanol recovery device of MTBE production equipment is controlled to rotate a power bevel gear by controlling a rotating motor, the power bevel gear is driven to rotate by utilizing the meshing of the power bevel gear and a transmission bevel gear, thereby driving a rotating shaft to rotate, then a mounting rod is driven to directionally rotate by utilizing the meshing of the power gear and the transmission gear, thereby driving a stirring rod to rotate, thereby driving a raw material mixed solution to stir, thereby reducing the time required for heating raw materials, accelerating the evaporation rate of the raw material mixed solution, and further improving the methanol recovery efficiency.
