Keywords:Catalyst dryer - catalyst belt dryer

First, the process conditions:
1, the name of the material: catalyst
2, early moisture: ~ 20% (wet basis)
3, the final water: ~ 5-6% (wet basis)
4, dry product output: ~ 1042 kg / h
5, dry product size: spherical 5--8mm
6, dry product weight: ~ 0.7-0.8 g / cm3
7, drying temperature: ~ 250 ℃ (mixed)
8, heating method: direct gas stove
9, the nature of water: surface water
10, sticky: no
11, equipment materials: material contact at 304, the remaining A3 production
12, installation: indoor
13, power supply: 380V 50HZ three-phase four-wire
Second, process calculation (theory)
1, dry product output: ≈ 1042kg / h
2, water evaporation: ≈ 196 kg / h
3, wet treatment capacity: ≈ 1238 kg / h
4, dry air consumption: ≈ 5448 kg / h
5, heat consumption: ≈ 384160kcal / h
Third, equipment selection (working principle and structural characteristics and the main technical parameters):
 According to the needs of the proposed use: DW2-14 belt dryer 1 Taiwan
    (A) How it works:
     Wet materials evenly spread on the net belt, the net material on the belt driven by the motor drive uniform forward movement. The heated hot air is blown into the drying cabinet through the circulation fan and penetrates the material layer evenly up and down. Hot air and wet material contact temperature dropped rapidly, the wet material absorbs heat in the hot air quickly heat and mass transfer exchange, the internal moisture quickly transferred to the outside, and by the hot air to the surface moisture away. Take away the wet air discharged by the exhaust fan outdoor.
     Drying at the beginning, hot air and wet material temperature is larger, is a constant speed process, the drying speed is very fast, with the drying, the moisture in the material is getting lower and lower, the temperature difference between the hot air and the material is relatively lower, the drying speed The slower, the temperature of the material is also gradually increased. (The heat provided by the hot air is mainly used in four major parts: evaporation of water, heating of materials, heat loss of equipment, and heat away from the exhaust gas.)
     Mesh belt dryer drive motor frequency control, so you can effectively control the feeding speed and drying time to meet the final moisture requirements of the product. Both sides of the mesh belt with a fixed block, to prevent the material blowing to the track and the chain up. The lower part of the support rod φ21 × 2, the support rod at both ends of the fixed on both sides of the chain on the track (the chain of flexible ball operation, the chain is moving forward by rolling friction between the ball and the track.) Support rod And net with Zhansi fixed, to prevent the relative sliding, extending the life of the net. In and out of the two ends of the spindle, the main sprocket fixed on both ends of the spindle, work with the chain of synchronous operation.
The bottom of the main body of the cabinet 12 channel steel and the surrounding skeleton No. 10 square tube welded together, insulation thickness 100mm, the use of high-quality aluminum silicate cotton, minimize equipment heat loss. The interior of the device is 1.2mm304. The exterior of the mainframe is 1.5mm A3 steel spray paint. Damp air duct 304. The mainframe side of the cabinet are opened with observation doors and cleaning doors, you can keep abreast of material drying operation. The box is equipped with a thermocouple, the XMT instrument in the control cabinet shows the working temperature of the cavity. Humidification duct has a regulating valve, you can adjust the amount of moisture discharge.
