Wherein the waste recycling device comprises a superheated steam generator for producing superheated steam, and a heat source is required to heat water and/or steam during operation of the superheated steam generator, thereby producing superheated steam. The waste regeneration treatment equipment also comprises a regeneration treatment furnace, wherein the regeneration treatment furnace is used for carrying out combustion treatment on the carbon fiber reinforced composite material waste, pyrolysis gas can be generated in the regeneration treatment furnace, and the pyrolysis gas can be conveyed into the heat energy conversion combustion furnace through a pipeline. The heat energy conversion combustion furnace can generate high-temperature hot gas by burning pyrolysis gas, and the high-temperature hot gas can be used as a heat source to be provided for the superheated steam generator and/or the regeneration treatment furnace so as to meet the working requirements of the superheated steam generator and the regeneration treatment furnace, form heat source circulation in waste regeneration treatment equipment and reduce cost.
It is worth to say that, at present, china still remains in the primary stage for the recovery of fiber reinforced composite materials, and no large-scale industrialized recovery exists, so that the environment-friendly equipment for recovering the glass fiber reinforced composite materials in a large-scale, continuous, low-cost and low-energy-consumption manner by using a pyrolysis method is a blank. In the global scope, only a few companies such as japan, germany, uk and the like have fiber reinforced composite material recycling industry, and most recycled regenerated fibers have seriously reduced strength, high recycling cost and heavy environmental pollution.
It will be evident to those skilled in the art that the application is not limited to the details of the foregoing illustrative embodiments, and that the present application may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
