Product description

Oil sludge refers to the general term for the hazardous solid waste consisting primarily of petroleum components formed in the petroleum extraction, smelting, storage, and transportation processes in petrochemical industry. Its main components are crude oil and refined oil, silt. After thorough emulsification and mixing with water, it is formed into the black viscous colloidal substances, which is difficult to separate and recover; and contains the heavy metals (copper, chromium, zinc, mercury, etc.) that will cause serious environmental pollution, as well as some radioactive and harmful substances that will pose a serious threat to human life and the entire ecological environment of the earth.

Due to the hazardous characteristics of oily sludge, in the process of the harmless disposal and resource utilization of oily sludge, it is necessary to apply in accordance with the requirements of the [Environmental Prevention and Control Law for Solid Waste Sludge" and the [Administrative Measures for the Operational License for Hazardous Wastes", and to deal with hazardous waste business licenses.

In practice, regardless of disposal or utilization, the first step must be the sludge dewatering, that`s the reduction of sludge. However, because of its special composition, sludge has high water content, large volume, and big difficulty, which is the problems that plague petrochemical enterprises.

ZJN [Rotary Rake Three Pass Multi-loop" Dryer for high-humidity and high-viscosity oil sludge is specially designed for solving these problems. A number of national patent technologies have been adopted by the drying equipment includes the guiding and lifting devices, the material feeding method, the thermal energy distribution and hot air volume control etc. The success operation in several large petrochemical enterprises fully proves that this set of equipment has a very satisfactory drying effect on oil sludge. Now it has been imported to a number of petrochemical enterprises such as Russia, India, Malaysia and Saudi Arabia. The prospects are very promising!

What ?!

What is a rotary drum dryer ?

Rotary drum dryer also is named rotary drying machine, rotary cylinder dryer, rotary drying machines which is widely used in the industrial drying field.
A rotary dryer, or rotary drum dryer, is a slightly inclined rotating horizontal cylinder that uses a supply of heat to continuously dry a solid material. As the drum/Cylinder rotates, wet solids are fed into the inlet end and slowly make their way to the discharge end. The inside of the drum dryer includes flights designed to lift and/or mix the material inside. This helps promote heat transfer efficiency in the material.

Why ?!

Why choose the rotary drum dryer for sludge dewatering ?

The purpose of sludge dewatering is for waste minimization and to achieve overall cost efficiency for disposal .Additionally ,it can also help with a company`s sustainability objectives .Generally both the public and private sectors are required to dispose of sludge in a manner that is approved by regulatory agencies,and are in line with their own organizational requirements and environmental safe .
Sludge dewatering is typically focused on reducing the weight and volume of the sludge so that disposal costs-including transportation are kept to minimum .Water removal is the primary means of volume reduction before sludge waste can be treated of disposal of in the most economical manner .

Which ?!

The heat energy for drying is supplied in two basic ways.
The first is by heating air or gases and blowing them directly into the drum where they come in contact with the wet material. This type of drum is called a direct-fired rotary dryer and the hot gas stream either flows in the same direction as the material moving through the drum (co-current flow) or opposite to the material movement (counter-current flow).

The second method of heat delivery is by heating the shell of the drum and is called an indirect-fired dryer. This is done using jacket heaters (steam jacketed, etc.) or by encasing the rotating drum in a furnace. Either way, the atmosphere inside the drum is controlled, protecting the material from certain gases.

Rotary drum dryers are chosen by industry for their dependability and low cost. Not only are they rugged, but they are also a reliable method for producing consistent product when feed stock may vary. In addition, rotary drum dryers allow for zones within the drum to perform multiple processes. For example, a single rotary drum may include a zone for drying and a later zone for classifying.

Applications ?!

Typical Materials Dried in a Rotary Drum Dryer
--- Fertilizers
--- Sludge dewatering
--- Biomass - Wood Chips, Energy Crops, and Other Materials
--- Minerals - Sands, Clays, and Other Minerals
--- Sewage Sludge
--- Animal Feeds - Cereal Grains, High Protein, Wastes, and By-Products
--- Foods - Cereals, Fruits and Vegetables, Starches, and more

Here is the point !

If you are in need of rotary drum dryer for drying wet material, please supply more of your requirement information as follows:
--- The features of raw material, for example the wet sand has surface water which is easier to be dried, but the wood chips has inner water which is more difficult to be dried.
--- Initial moisture content(%) of the wet material.
--- Output moisture content(%) the dried material needed.
--- Bulk density (kg per cubic meter) of the wet material.
--- Input capacity (ton per hour).
--- Output capacity(ton per hour).
--- Fuel Choice such as coal, waste wood, natural gas, diesel, etc.
--- End use of the dried product.
