Abstract
The invention discloses a treatment system for DMTO catalyst production wastewater, and belongs to the technical field of chemical equipment. The treatment system comprises a sedimentation tank provided with a liquid inlet, a liquid outlet and a residue discharge port, wherein the liquid outlet of the sedimentation tank is connected with a reduced pressure evaporation device through a pipeline, and the water outlet of the reduced pressure evaporation device is connected with a distilled water tank through a pipeline; the residue discharge port of the sedimentation tank is connected with a residue collection tank through a pipeline, and a residue discharge port of the reduced pressure evaporation device is connected to the residue collection tank through a pipeline. The whole treatment device does not need pouring of any chemical agent, and has a short evaporation time, a high separation accuracy, a small floor area, a simple operation, reliable running and convenient maintenance; the catalyst residue separated by the system can be roughly processed and then recycled.
Description
technical field [0001] The invention belongs to the technical field of chemical equipment, and in particular relates to a treatment system for waste water produced by DMTO catalysts. Background technique [0002] my country is a country with a serious shortage of fresh water resources. Water resources and water environment problems have become one of the main factors restricting industrial development. Realizing "zero discharge" of wastewater is the self-need and external requirement of industrial development. "Zero discharge" of wastewater is the Wastewater generated during the process is treated and then recycled. [0003] DMTO is a technology that uses coal or natural gas instead of petroleum as a raw material to produce ethylene and propylene. The industrialization technology of methanol to low-carbon olefins (DMTO) solves the technical bottleneck of coal-to-olefins. It is a bridge connecting coal chemical industry and petrochemical industry. Industry and coal-to-olefins...
