Organic Fertilizer Drying

Constitute:Hot Air System + Drying Unit + Tail Gas Treatment

Brief Introduction Of Organic Fertilizer Dryer

Organic fertilizer, also known as "farm manure", not only contains a large number of micro elements needed by plants, but also contains rich organic nutrients, suitable for wheat, rice, peanuts, fruits and other crops to fertilize. Organic fertilize can improve the quality of crops, improve the quality of fruits and melons. It is a good choice of pollution-free green food planting fertilizer.

Organic fertilizer dryer can use chicken manure, duck manure, livestock and other feces, slaughterhouse waste for dehydration and drying treatment, open up feed resources, reduce feeding costs, but also can reduce environmental pollution.

The Organic fertilizer is sent to the first stage dryer with the hot air. In which there is provided with “Rotary Harrow Rolling Crushing Device.” Under the action of this device, the wet materials is broken into the scattered condition, and with constantly rolling, rotating and separating of the material, so that its surface forms a "dry shell", effectively avoiding the particles from agglomerating again. During the constant lifting of the material with continuously flipping, it fills the entire drying space and fully contact with the hot air, then the wet material can be fully utilized the thermal energy and enhance the evaporation of the moisture intensity, and become the loose shape. Thus completing high humidity → not wet, high viscosity → no sticky, high-viscosity→non-sticky important conversion.

Working Principle Of Organic Fertilizer Dryer

Organic fertilizer dryer using "three positive and negative, guide material" and "W+S" three cylinder stage material walking process, can make the material in the equipment to do repeated movement, namely the so-called "three steps back two steps", enhance the evaporation; The storage capacity of the equipment is large, three times that of the traditional dryer.

The heat transfer area is wide, four to five times that of the traditional dryer; The drying stroke is long, six times that of the traditional dryer. In this way, the heat energy and space utilization rate inside the cylinder can be greatly improved, the moisture evaporation inside the material can be accelerated, and the wet material after drying can be guaranteed to be uniform dried, and the finished product quality is good.

Hot Air Heat Source

We have different hot air generating device for you. According to your Heat Source, no matter it is natural gas, bio-gas, coal, oil, bio-mass fuel or others, we match furnace, chamber, burner etc to be most suitable. What's more, the boiler flue gas can also be used as heat.

Suitable Materials For Organic Fertilizer Dryer

Organic manure dryer is suitable for animal manure (such as chicken manure, duck manure, goose manure, cow manure, horse manure, pig manure, etc.), plant residues, animal residues, slaughterhouse waste, cake fertilizer, compost, compost, manure, digestate, green manure and other materials drying.

Widely used in agriculture, feed, fertilizer industry, etc.

Exhaust Gas Emission Collecting System

Scrubber

Scrubber systems (e.g. chemical scrubbers, gas scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams.

The exhaust gases of combustion may contain substances considered harmful to the environment, and the scrubber may remove or neutralize those. A wet scrubber is used for cleaning air, fuel gas or other gases of various pollutants and dust particles. Wet scrubbing works via the contact of target compounds or particulate matter with the scrubbing solution. Solutions may simply be water (for dust) or solutions of reagents that specifically target certain compounds.

Cyclone Dust Collector

Centrifugal cyclone dust collector, the dust will be separated and recovered in the drying system, through the dry tail gas dust purification device of a cyclone dust collector, suitable for high dust concentration, large dust particles of exhaust gas dust removal operations, the dust collector has a simple structure, stable and reliable operation, long service life, and other characteristics.

Baghouse

A bag house, also known as a bag house filter, bag filter, or fabric filter is an air pollution control device and dust collector that removes particulates or gas released from commercial processes out of the air.

Most baghouses use long, cylindrical bags (or tubes) made of woven or felted fabric as a filter medium. For applications where there is relatively low dust loading and gas temperatures are 250 °F (121 °C) or less, pleated, non woven cartridges are sometimes used as filtering media instead of bags.

Bag houses are very efficient particulate collectors because of the dust cake formed on the surface of the bags. The fabric provides a surface on which dust collects through the following four mechanisms:

Inertial collection – Dust particles strike the fibers placed perpendicular to the gas-flow direction instead of changing direction with the gas stream.

Interception – Particles that do not cross the fluid streamlines come in contact with fibers because of the fiber size.

Brownian movement – Sub micrometre particles are diffused, increasing the probability of contact between the particles and collecting surfaces.

Electrostatic forces – The presence of an electrostatic charge on the particles and the filter can increase dust capture.

A combination of these mechanisms results in formation of the dust cake on the filter, which eventually increases the resistance to gas flow. The filter must be cleaned periodically.
