Embodiment 1
[0041] An inorganic lightweight aggregate spray cooling system, refer to figure 2 , which includes a gas-solid separation device 5 with a cylindrical body and a funnel-shaped bottom. The cylindrical main part of the gas-solid separation device 5 is provided with a material inlet 4 and a waste gas outlet 6, and a finished product outlet 7 for discharging the separated finished inorganic lightweight aggregate is opened at the bottom. Material inlet pipe 41 is connected to 4 places of material inlet, and waste gas outlet pipe 61 is connected to 6 places of waste gas outlet. Inorganic lightweight aggregate is conveyed by pneumatic force, and enters the gas-solid separation device 5 through the material inlet pipe 41 and the material inlet 4; after the inorganic lightweight aggregate particles are settled in the gas-solid separation device 5, they are discharged from the finished product outlet 7, and the dusty waste gas is discharged from the The waste gas outlet 6 is discharged...
Embodiment 2
[0048] A kind of inorganic lightweight aggregate direct spray cooling method, it is based on embodiment 1, specifically comprises the following steps:
[0049] Step 1. Feed the inorganic lightweight aggregate to be cooled into the gas-solid separation device 5 of the inorganic lightweight aggregate spray cooling system in Embodiment 1 through the material inlet pipe 41 by means of pneumatic conveyance.
[0050] Step 2: open the valve 8 and the metering pump 2, use the pipeline 9 to pass the clean water in the water tank 1 into the spray device 3, and spray water mist to the inner space of the gas-solid separation device 5 . In order to ensure the spraying effect, the spraying device 3 adopts a hydraulic direct injection nozzle, and the particle size of the sprayed water mist droplets is controlled to be ≤300 μm by adjusting the pressure of the nozzle. The mass ratio of spray amount to inorganic lightweight aggregate is controlled at 0.1:1-1:1, and the specific spray amount can...
