Description:

Fly ash dryer applies to fly ash, phosphogypsum and titanium gypsum etc. industry dust, waste residue drying.Fly ash dryer is designed by the features of early moisture is higher than other materials; the proportion is less than other materials, big flow ability during dry process.

Features:

1. With compact structure, small floor area, reliable working, low energy consumption, high thermal efficiency, material drying effect is good, easy to realize automation control, few operators.

2. Low air out temperature, dust removal equipment can be used long time.

3. Adopting new combined type raising device, according to users’ demand regulate and control the required eventually moisture target breezily.

relaxed regulation to end moisture indicators.

4. High degree of automation, easy operation, stable working.

5. Equipment investment is imported products 1/6, small investment, gains fast.

6. Equipment is new energy-saving products, it can energy saving about 20% than similar products.

7. Fuel can adapt to coal, oil, steam etc.

Design system: (noted question)

1. Control the early moisture content: The moisture of wet fly ash which just discharged from the power plant is in commonly around 45%. If dry the fly ash at once, the production cost is higer, it will form bigger pressure to the equipment. If pile up at a draughty area for about 15 days, the moisture of fy ash reduced to about 20%, then handle the materials is a better way.

2. The selection of dust collector. Because of fine fly ash particle, light density, in negative pressure state after drying, it is easy to take away by airflow, lead to the fluid media change, and the dusty gas moisture is bigger.

Dust catcher should be based on the above process state choice.

3. Dry materials conveying equipment should pay attention to seal.

4.The selection of hot air stove. Hot air stove should be choosed high efficiency, fully burn poor quality coal, convenient operation of the furnace type.
