Split, possessing again can cure.
The process route of conventional dynamic is：A certain amount of water is added in pressure resistant vessel, is first filled with water vapour to 0.8-
1.0MPa（Temperature is at 160-180 DEG C or so）, then in outer wall electricity consumption or conduction oil progress reheating, or do not fill steam and directly use
External heat, container inner pressure is set to be increased to more than 2.0MPa, for a period of time, then pressure release cools, and releases the glue in container for pressurize
Material, complete regenerative process.
To make scrap rubber in container reach the pressure of regeneration needs, it is necessary to be heated in outer wall, but because of the glue in container
Material is the relatively low leather hard solid powder of heat-transfer capability, it is necessary to which higher thermograde improves heat-transfer capability, general control wall
Temperature is more than 280 DEG C, and even as high as 350 DEG C, at this temperature, the rubber contacted with wall can be cracked into lower-molecular substance and carbon
Compound, low-molecular material caused by cracking produce pollution to environment, and carbide, which is adhered on wall, further reduces heat transfer coefficient,
With wall can be caused to overheat bulge during electrical heating, safety is influenceed.Simultaneously as heat transfer temperature difference is big, wall of reactor quantity of heat storage is more,
Thermal inertia is big, reaction terminating temperature is not easy to control, and causes quality unstable.Turn into hardly possible after the gas condensation process released during pressure release
The organic wastewater of processing, direct reuse, product quality can be caused to decline and peculiar smell is overweight, qualified discharge after processing, expense is high-leveled and difficult
Degree is big, also has part low boilers to condense out after condensation process, has strong peculiar smell, serious dirt is caused to environment
Dye.Therefore, pollution and safety problem constrain the use of this method, have impact on the recycling of scrap rubber.
The content of the invention
It is an object of the invention to provide a kind of scrap rubber to clean renovation process, and concrete scheme is：
