2. Public works:

1. Installed capacity: 39.25KW

2. Compressed air consumption: 0.4m3/min, pressure: 0.5~0.6MPa

3. Description of main equipment configuration and technical performance:

1. Spray drying tower:

Model: LPG250 (drying volume: 65m3)

Tower diameter: 4m, straight section height 4m, cone height: 3.2m (lower cone angle: 60 degrees)

Cold wall: 75mm, tower lighting: 200W, including observation cleaning door

(1) Since urea-formaldehyde resin is thermoplastic, the temperature of the drying tower wall must be kept low, so a cooling air jacket is installed on the wall of the straight section of the cylinder, and a rotating cold air cleaning device is installed inside the tower to avoid sticking to the wall. .

(2) In order to prevent the dry powder from accumulating in the cone under the tower body, a rapper is installed in the cone, so that the powder can be discharged from the discharge port in time to ensure the continuous and stable operation of the equipment.

2. Atomizer:

Model: LPG-300-5.5KW

Processing capacity: ~600kg/h

Atomizing disc diameter: 150mm, rotating speed: 15500rpm

Cooling: forced cooling by external circulation of pump oil

3. Feeding pump:

Model: GF15-2-0.75KW

Feed rate: 0~0.63m3/h, discharge pressure: 1.2MPa

Flow adjustment: frequency conversion speed regulation

4. Cyclone separator:

Model: XF-950

5. Bag filter

Model: MF-108

Bag specifications: φ1200×2000mm, bag quantity: 108
