System for preparing ethyl hexyl copolymer through slurry method and filter pressing process

The invention discloses a system for preparing an ethyl-hexyl copolymer through a slurry method and a filter pressing process. The system comprises a polymerization reaction unit, a slurry solid-liquid separation unit, a drying and devolatilization unit, a non-condensable gas recovery unit and a solvent refining unit. The invention provides a system for preparing an ethyl-hexyl copolymer by a slurry method, which takes pentane as a solvent and can be applied to large-scale chemical engineering. In the slurry solid-liquid separation unit, continuous solid-liquid separation and solid drying are carried out in a manner of a pressure filter. And the recovered polymerization solvent mother liquor directly returns to the reactor and is partially refined. The size of subsequent drying equipment for polyolefin resin can be reduced, the equipment investment and land occupation are reduced, meanwhile, part of the polymerization solvent directly returns to the reactor without phase change, and the separation energy cons
