The sewage sludge treatment plant designed by Beston Group mainly refers to processing sewage sludge into charcoal through a series of reactions. The plant is also known as sludge carbonization machine, industrial sludge management system, sludge treatment facility, sludge to energy project, etc. Besides sewage, the carbonization machine can be also used for dealing with municipal solid waste (MSW) and biomass materials, such as rice husk, wood, coconut shell, plant straw, palm shell, sawdust, bamboo, etc., which is the so-called “one machine with multiple uses”.
Working process of Beston industrial sewage sludge treatment plant
1. Dry the sewage sludge with high temperature
In general, the moisture of sewage sludge is quite high, which is not convenient for carbonization. So we have installed a dryer device to remove the extra moisture in the sludge and guarantee the water content of sludge in no more than 20%. the pretreatment can ensure the quality of end products and reserve more charcoal contents.
2. Carbonization of sludge
Using coal, wood or natural gas as fuel to heat the carbonization furnace for 30 minutes until there is combustible gas generating in the furnace. The combustible gas is the major burning fuel materials in the sewage sludge treatment process. After purified by spray dedusting system, the gas will be recycled to heat furnace and dryer instead of traditional fuels, which is the famous carbonization technology of “one fire with two steps”.
3. Discharge of sludge carbon
After being heated by the furnace and then cooled by cooling system, the sludge will be slowly converted into charcoal and we can discharge the charcoal automatically.
End product from sewage sludge carbonization machine
The final products generated from Beston sludge treatment and disposal system includes: sludge carbon (also called charcoal), soil, water vapor, combustible gas, a small amount of wood vinegar and tar. The combustible can be purified and recycled for heating the carbonization furnace or dryer. Both wood vinegar and tar are chemical materials, and can be used for industry areas. The sludge charcoal is the main final product we can get, which can be widely applied in many areas:
1. In daily life: can be used as fuel in BBQ or other cooking areas;
2. In agriculture area: it can be used to improve the quality of soil;
3. In industry area: can be further processed into activated carbon; used for construction bricks with clay; or widely used as fuel in industries such as steel and iron factories, ceramics and so on.
Special design of Beston sludge management system
1. Continuous loading equipment
The sludge carbonization treatment equipment consists of a wide range of hopper as well as screw conveyor integrally that is located straight in its bottom or lower part. With a screw conveyor to automatically and continuously feed raw materials into the carbonizing furnace for charcoal, it has the ability to work at a high level of efficiency, which makes it one of the best alternatives available for sale.
2. Hot air production furnace
Its hot air production furnace can create a high-temperature environment with low-oxygen air, which is necessary for carbonization before feeding raw materials. In this way, the industrial sludge carbonization process will be energy-saving and high-efficiency.
3. Closed carbonization furnace system
A sludge treatment plant features a horizontal steel closed carbonization kiln, which is capable of carbonizing both dry sludge and dehydrated sludge through an agitating blade. This is the most striking feature that has made it to be almost completely maintenance-free, which will help the company save money when working on huge quantities of sludge.
4. Unloading equipment feature
The sludge carbonization treatment equipment has unloading equipment feature that consists of the transfer conveyor capable of serving as a cooling equipment, as well as the main carbide storage tank. It also enables easy transfer of sludge from one level to another especially in cases when the company does needs the best outcome or result.
5. Exhaust gas treatment equipment
The exhaust gas generated in the process of carbonization is always purified and deodorized through re-combustion within the secondary combustion chamber, which is finally discharged through the air blower.
With the world’s development, environment projects have drawn more and more attentions. The treatment of sludge has become more and more important.
