Mixing and unloading device for preparing ethylene glycol by two different processes in PET (Polyethylene Terephthalate) production device

The utility model relates to the technical field of ethylene glycol unloading devices, in particular to a mixed unloading device for ethylene glycol prepared by two different processes in a PET (polyethylene terephthalate) production device, which comprises a petroleum ethylene glycol storage tank and a coal ethylene glycol storage tank, the petroleum ethylene glycol storage tank is communicated with a petroleum ethylene glycol inlet pipeline, and the coal ethylene glycol storage tank is communicated with a coal ethylene glycol inlet pipeline. And an unloading pump A is fixedly mounted on the petroleum-to-ethylene glycol pipeline. The ethylene glycol unloading system is reasonable and compact in structure and convenient to use, compared with a traditional ethylene glycol unloading system, standby conditions of the unloading machine pumps are guaranteed, meanwhile, the installation number of the on-site machine pumps is reduced, on one hand, the one-time investment cost of enterprises is effectively reduced, o
