Description
＜one〉technical field
The present invention a kind of processing method and device thereof to the waste products that contains brominated epoxy resin and glass fibre, mean that a kind of waste products that will contain brominated epoxy resin and glass fibre adds in the inorganic salts of fusion, comes hot tearing to solve the method and the device of the raw materials of industry such as Bromide class and glass fibre.
＜two〉background technology
Epoxy resin is a kind of filler of fairly good usefulness, but its shortcoming is inflammable, so in order to improve its flame resistance, at present all be this epoxy resin to be handled through bromination obtain the high brominated epoxy resin of flame resistance (DGETBA), and because this brominated epoxy resin also has the characteristics such as adhesive force of splendid insulating properties and enhancing and metal, so present industrial circle often is to utilize this brominated epoxy resin as solid, it is bonding to make the engineering plastic plate except being used for glass fibre, also be used in large quantities on the various electric products simultaneously, for example as the insulating materials on electric, circuit board, or other special spare part etc.; Only, this contains the engineering plastic plate or the other products of brominated epoxy resin, in case become waste products, the glass fibre that recyclable recirculation is used in its structure, and can't recycle in the mode of incinerating, and, this waste products is molten condition time receiving back and forth if being heated to this glass fibre, the high-temperature service that then must setting can be heated to more than thousands of degree ℃ can be reached, do not meet economic benefit, in addition if reclaim glass fibre in the waste products in the mode of thermal cracking, this brominated epoxy resin can produce the hydrogen bromide (BrH) of serious environment pollution again in its process, so in recent years in the waste products for engineering plastic plate that contains brominated epoxy resin or other products, it is infeasible reclaiming glass fibre at all, it only can let alone to stack wantonly, and this not only causes the waste of resource, and the tough structure that is difficult to decompose of this waste products killer that destroys environment especially.
The present invention's main purpose is to utilize the molten salt can be directly and the characteristic of bromine reaction, this is contained the inorganic salts of putting into fusion in the waste products of brominated epoxy resin, can produce stable harmless bromination salt (as sodium bromide) after making its reaction, and can work as the organic gas of fuel as energy recovery, cleavable reclaims pure glass fibre again simultaneously, and uses for recycling as the raw material of industry.
The present invention's another purpose, be hot tearing to solve highly purified glass fibre with the molten salt class of 300 ℃ to 500 ℃ of temperature, do not need to use and have the firing equipment that is heated to more than thousands of degree ℃, make whole recovery handle the more simple and easy and reduction processing cost of process of glass fibre, and meet the economic benefit of recovery.
Another object of the present invention, but be that a completing combustion apparatus is being provided, must when this molten salt thermal cracking brominated epoxy resin, after the organic gas completing combustion that is produced, change into the steam and the carbon dioxide of environmental sound.
