Embodiment 1
[0029] A comprehensive disposal method for glass fiber waste, comprising the steps of:
[0030] S1. Deep dehydration: Add glass fiber waste gas desulfurization ash particles and calcium peroxide particles with a particle size of less than 2mm to the glass fiber waste slurry with a water content of 90%, stir and mix, press filter and dehydrate to obtain a mud cake, the mud cake The moisture content is 53.8%, the amount of calcium peroxide is 1% of the dry weight of glass fiber waste slurry, and the amount of glass fiber waste gas desulfurization ash is 20% of the dry weight of glass fiber waste slurry;
[0031] S2. Crushing and pyrolysis: crush and disperse the mud cake in S1 until the particle size is less than 10mm, put it into the gasifier for pyrolysis at 300-500°C, collect the hydrogen-rich gas and pyrolysis ash generated by pyrolysis respectively, Pyrolysis ash is powdery particles with a particle size below 2mm;
[0032] S3. Blending: glass fiber waste gas desulfurizati...
