Dryfree solar air collector for commercial dry

For some market without electricity, customer will only use 100% solar power to dry different goods, then we design fixed commercial solar dry system for customers.

Commonly we design one line with 5pcs and two lines with 10pcs.If have no space to install, we can adjust 3pcs with three lines as total 9pcs to install up high.

Solar collector is standard type as 2000mm x 1000mm x 82mm thickness with polyurethane foam and strong frame and tempered glass.

We will install air input with dirt filter screen and hot air output tube and connect 10pcs collector with steel tube together as total solar dry system. Customer only need to install them on roof or ground and use soft tube to connect with basement, bricks room or other drying room to keep working. That should be very easy to operate and can use 100% free for solar.

If need bigger solar dry capacity, we can parallel connect every set ( as 10pcs with one set ) together with hot air tube, and that should be very easy to operate.

Low temperature sludge drying equipment

Dryfree sludge dehumidification and drying machine uses dehumidification heat pump to dry sludge with hot air circulation condensation dehumidification. When adopting belt drying equipment, 90% of the heating capacity of traditional sludge heat drying system is converted into exhaust air heat loss (latent heat of water vapor and sensible heat of hot air).

Dehumidification heat pump is a kind of device that makes use of refrigeration system to cool and dehumidify hot air and recycle air moisture condensation latent heat to heat air through heat pump principle.

Dryfree sludge dehumidification and drying characteristics

Environmental

1. Choosing closed drying mode, without odor overflow, and no need to install complex deodorant device.

2. Using low temperature drying process, the amount of H₂S and NH₃ precipitation is greatly reduced.

3. Suitable for installation in urban sewage plant.

4. Condensed water (sludge moisture) treatment is simple (or direct discharge), saving the cost of condensed water treatment in the drying process.

Safe

1. Below 80 ℃ low temperature drying process

2. Static amortization, no mechanical static friction with the contact surface

3. No "sticky phase" stage of municipal sludge drying process (about 60%)

4. Dry material is granular without dust hazard.

5. Discharging temperature is low (< 50 ℃); no need for cooling, can be stored directly.
