Product Description

Sludge drying is an essential intermediate treatment process designed to evaporate the water content in sludge. This process transforms sludge into valuable products or eco-friendly fuel. By removing water, it significantly reduces storage volume and transportation costs, making the sludge easier to handle and manage. The resultant reduction in volume and weight facilitates more efficient recovery and disposal.

Sludge, a byproduct of municipal sewage processing, presents several challenges due to its high moisture content, viscosity, water holding capacity, and low calorific value. These factors complicate its industrial utilization. Zhengzhou Jiutian Technology Machinery Co., Ltd., recognizing these challenges, embarked on extensive technical research into the current sludge treatment landscape and regional sludge characteristics. As a result, Jiutian has innovatively developed a new generation of sludge rotary drum drying systems. These advanced systems can reduce sludge moisture content to below 25%, meeting the rigorous standards for landfill and incineration processing. The technology is both mature and reliable, ensuring stable operation, ease of use, and straightforward maintenance.

Working Principle

 

^{Sludge Rotary Dryer Working Principle}

The Jiutian sludge drum dryer boasts a sophisticated composition, featuring a heat source, dispersing feeder, belt feeder, rotary drum, belt discharger, induced draft fan, dust collector, deodorization device, and power distribution cabinet. Here's how it operates: Initially, the wet sludge, with about 80% moisture content and a certain viscosity, enters the tumble dryer. It is then divided into six distinct drying working zones:
1. **Material Guide Area:** Upon entering, the wet sludge meets high-temperature hot air, rapidly evaporating moisture. If the material does not bond under the large lead angle copying plate, it moves to the next zone.
2. **Crushing, Beating, and Cleaning Area:** Equipped with specialized crushing, beating, and cleaning devices, this zone ensures the wet sludge is lifted, crushed, and formed into a material curtain to enhance the heat exchange area and drying rate. The cleaning device maintains the inner wall, preventing sludge adherence.
3. **Main Drying Area:** The semi-processed sludge is in a granular, loose state. The inclined lifting plate uniformly lifts the material for full heat exchange with hot air, enabling robust moisture removal.
4. **Beating, Crushing, and Drying Area:** Here, the sludge undergoes repeated beating and breaking, reducing particle size from 20-40mm to 10-20mm (as per customer requirements), facilitating further moisture reduction.
5. **Enhanced Drying Area:** Small particle sludge, lifted by a dense copying plate, maximizes hot air absorption, meeting the required moisture standards and preparing for discharge.
6. **Discharge Area:** To prevent dust discharge, this zone lacks a copying plate. The dried sludge, with moisture content reduced to 20-25%, rolls to the discharge port, completing the drying process.

^{Dust Removal and Deodorization Equipment Our system employs a comprehensive four-stage dust removal and deodorization approach. The first-stage cyclone dust collector extracts dust particles from exhaust gas. The second stage uses acid washing to neutralize odors, while the third stage employs alkali washing for further odor removal. The final stage utilizes ultraviolet ray decomposition, effectively controlling the odor gas within 2000 dimensionless units.}

Product Features

 

1. Versatile Heat Source: The machine can utilize a range of economically friendly heat sources such as low-cost steam, biomass, natural gas, and coal.

2. User-Friendly Digital Control: Equipped with a straightforward and intuitive digital control panel, this machine ensures effortless operation and maintenance.

3. Significant Sludge Reduction: Experience a dramatic decrease in sludge weight by approximately 60%, with a volume reduction of 4-5 times.

4. Cost-Efficient Transportation: The substantial reduction in both weight and volume leads to significantly lower transportation costs for sludge.

5. Enhanced Calorific Value: By reducing moisture content, the calorific value of the sludge is effectively increased.

6. Sterilization and Deodorization: The high drying temperatures ensure that the sludge is both sterilized and deodorized, promoting a safer, cleaner process.

Applications

 

Our Industrial Rotary Dryer Drum Drying Machine is renowned for its versatility and effectiveness. It is extensively employed for drying a diverse range of sludges, including but not limited to electroplating sludge, tannery sludge, chemical sludge, oil field sludge, and municipal sewage treatment plant sludge. Additionally, it is adept at processing activated sludge, sewer sludge, petrochemical sludge, paper sludge, printing and dyeing sludge, and biological fermentation bacteria residue. This cutting-edge machine is also suitable for drying other high-humidity materials such as various kinds of dregs, making it an indispensable asset in numerous industries.
