Embodiment Construction
[0038] The method for slag granulation and sensible heat recovery provided by the present invention and the slag granulation and sensible heat recovery system using the method will be described in detail below with reference to the accompanying drawings.
[0039] A method for slag granulation and sensible heat recovery provided by the invention comprises the following steps:
[0040] 1) Let the slag flow into the shell from the leakage bag to form multiple columnar slag flows, and the multiple columnar slag flows are arranged in at least one row, and the number of strands of each columnar slag flow is at least two;
[0041] 2) Install at least one nozzle in the shell with water cooling wall, pressurize the water to 1MPa ~ 400MPa with a high-pressure pump, and spray it from at least one nozzle to form a columnar high-speed water jet with a flow rate of at least 45m / s at the outlet of the nozzle;
[0042] 3) The high-speed water jet impacts the multiple columnar slag flows on th...
