Embodiment 1

[0034] Such as figure 1 As shown, the polymer material continuous processing equipment of the present invention includes a processing furnace 1, a steam generator 2, a transmission mechanism 3, an exhaust system 4, a cooling device 5, an oil-water separator 6, an air storage tank 7, and a temperature control system 8 And the steam heating pipeline 9, the saturated steam output end of the steam generator 2 is connected with the treatment furnace 1, the cracked carbide output end of the transmission mechanism 3 is connected with the treatment furnace 1, and the pyrolysis combustible gas water vapor output end of the transmission mechanism 3 passes through The exhaust system 4 is connected to the cooling device 5, the output of the cooling device 5 outputs combustible gas and is connected to the input of the gas storage tank 7, the output of the gas storage tank 7 is connected to the processing furnace 1, and the superheated steam output of the processing furnace 1 The input end ...

Embodiment 2

[0038] The present invention uses superheated steam as a heating heat source and an oxygen-insulating medium, and controls the temperature in the transmission mechanism 3 and the treatment furnace 1 so that the high-temperature superheated steam is used for oxygen-free thermal decomposition of the polymer material during the transmission process, and the polymer material is in the absence of oxygen. Oxygen high-temperature superheated steam does not burn, oxidize, and produce harmful gases such as dioxin and carbon dioxide, and effectively decomposes polymer components such as resins, curing agents, and adhesives in polymer composite materials, and some materials that cannot be cracked can be damaged. Recycle. Specifically, anaerobic or micro-oxygen (oxygen content≤0.3%) superheated steam at a temperature of 450-600°C is introduced into the conveying mechanism 3, and the conveying mechanism 3 and the processing furnace 1 are kept in a slight negative pressure state by using the...

Abstract

The invention relates to a high polymer material continuous treatment method and device. Overheat steam is utilized as a high polymer material pyrolysis heat source and a fire retardant, the high temperature in a treatment furnace is utilized for heating saturated steam to generate overheat steam at the temperature ranging from 400 DEG C to 900 DEG C, and the oxygen content of the generated overheat steam does not exceed 0.3%; the overheat steam is led into a conveying mechanism, the whole conveying mechanism is kept with the micro negative pressure through an air draft system, it is ensured that in the high polymer material conveying and pyrolysis process, the overheat steam does not leak, the oxygen-free state is kept in the equipment, and the oxidation reaction of the high polymer material in the high-temperature decomposition state is effectively restrained. When the equipment works, the equipment is in the micro negative pressure state, and the system is safe and reliable. The treatment furnace and a steam generator are connected through a pipeline, the overheat steam generated by the equipment provides a necessary heating medium for high polymer material pyrolysis and also becomes the fire retardant for isolating air; and meanwhile, combustible gas and water vapor generated by high polymer material pyrolysis can be recycled and circularly used by the equipment, and accordingly zero emission and zero pollution are achieved.

Description

technical field [0001] The invention relates to a continuous processing method and equipment for polymer materials, belonging to the technical field of polymer materials. Background technique [0002] Polymer materials are divided into natural polymer materials and synthetic polymer materials according to their sources. Natural polymers are polymer substances that exist in animals, plants and organisms, and can be divided into natural fibers, natural resins, natural rubber, animal glue, etc. Synthetic polymer materials mainly refer to the three major synthetic materials of plastics, synthetic rubber and synthetic fibers, and also include adhesives, coatings and various functional polymer materials. Polymer materials are divided into rubber, fiber, plastic, polymer adhesive, polymer coating and polymer-based composite materials according to their characteristics. Various products made of polymer materials have permeated all areas of our life and industry, and this kind of w...
