Embodiment 1
[0032] The invention provides a method for preparing rock wool prepared by recycling waste materials, the preparation steps of which are as follows:
[0033] S1: Precursor processing: Cut the waste agricultural rock wool into 400mm blocks, pass the recovered waste agricultural rock wool through a press, squeeze the water in the waste agricultural rock wool, and dry it in a drying oven at a temperature of 180 ℃, drying time 3h, the heat used for drying comes from the waste heat of multi-stage heat exchanger, the waste heat of curing furnace and the waste heat of rock wool high temperature furnace, so that the heat can achieve the effect of recycling. After testing, the water content of rock wool residue does not exceed 1%;
[0034] S2: Burn the dried waste rock wool residue in a high-temperature furnace at a temperature of 700°C for 1 hour to burn off organic resins such as plant roots and fiber attachments contained in the waste agricultural rock wool. After testing the organi...
Embodiment 2
[0044] The invention provides a method for preparing rock wool prepared by recycling waste materials, the preparation steps of which are as follows:
[0045] S1: Precursor processing: Cut the waste agricultural rock wool into 400mm blocks, pass the recovered waste agricultural rock wool through a press, squeeze the water in the waste agricultural rock wool, and dry it in a drying oven at a temperature of 200 ℃, drying time 2.5h, the heat used for drying comes from the waste heat of multi-stage heat exchanger, the waste heat of curing furnace and the waste heat of rock wool high temperature furnace, so that the heat can achieve the effect of recycling. After testing, the water content of rock wool residue is not high. more than 1%;
[0046] S2: Burn the dried waste rock wool residue in a high-temperature furnace at a temperature of 750°C for 1 hour to burn off organic resins such as plant roots and fiber attachments contained in the waste agricultural rock wool. After testing t...
Embodiment 3
[0055] The invention provides a method for preparing rock wool prepared by recycling waste materials, the preparation steps of which are as follows:
[0056] S1: Precursor processing: Cut the waste agricultural rock wool into 400mm blocks, pass the recycled waste agricultural rock wool through a press, squeeze the water in the waste agricultural rock wool, and dry it in a drying oven at a drying temperature of 230°C , the drying time is 2.5h, the heat used for drying comes from the waste heat of multi-stage heat exchanger, the waste heat of curing furnace and the waste heat of high-temperature rock wool incineration furnace, so that the heat can achieve the effect of recycling. After testing, the water content of rock wool residue does not exceed 1 %;
[0057] S2: In a high-temperature furnace, the dried waste rock wool residue is burned at a temperature of 750°C for 1.5 hours to burn off organic resins such as plant roots and fiber attachments contained in the waste agricultu...
