Exhausted Heat Enclosed Sludge Dryer with Belt

 
Air source’ remaining heat sludge drying suits for the places with a stable source of industrial waste heat, such as power factories, chemical factories and steel factories.
And it suits for energy-sensitive projects that handling large volumes of sludge (daily processing volumes of tens to hundreds of tons).
Priority is given to areas with strict environmental protection requirements and prohibitions against waste gas and odor emissions.

Enclosed sludge dryer with belt suits for places with high requirements for dried product quality and the need for precise moisture control (e.g., 10%-30% moisture content) and it suits for projects with continuous production and uninterrupted processing requirements, such as municipal sludge and chemical sludge.Then it also suits for projects with relatively ample space and the ability to deploy continuous production lines.

Van-type sludge drying can suit for small and medium-sized projects with low sludge production (daily processing volumes of a few to tens of tons) and intermittent production, such as small sewage treatment factories and township sludge treatment stations and suit for sites with limited space that preclude the installation of large continuous equipment. And it also suit for users with a low initial investment budget and a willingness to accept batch operation.

The brief introduction of exclusive sludge handle machine to solve solid and waste disposal problems

This air-source sludge drying machine is a highly efficient and environmentally friendly machine specifically developed for handling municipal sludge and industrial sludge (such as chemical, printing&dyeing and food processing sludge).


Product Advantages: Three Core Highlights to Solve the Defects of Sludge Drying

1. High Efficiency and Energy Saving to Significantly Reduce Disposal Costs

Super-high energy efficiency ratio

Take advantage of the remaining heat recycle

Controllable operation costs


2. Environmental Compliance to Wipeout Secondary Pollution

Low-temperature and harmless drying

Enclosed exhausted gas Disposal

0 wastewater discharge


3. Stable and Intelligent to Significantly Reduce Operation and Repair Costs

Adaptable to different operating conditions

Intelligently automatic control

Durable and easy-maintenance design


Application Scenes: Comprehensive Coverage to Suit Different Sludge Disposal Needs

1. Municipal Wastewater Treatment Plants: Large-Scale Sludge Volume Reduction Treatment

Application scenes:municipal wastewater treatment plants with a daily wastewater treatment capacity of over 50,000 tons, generating an average of 5-50 tons of sludge (80% moisture content) per day.


Core values: efficiently handle large volumes of municipal sludge,reduce sludge volume by over 70% (80% moisture content to 30%) and significantly reduce sludge transportation and landfill costs. Low-temperature drying can prevent the spread of odors and improve the environment of sewage treatment plants and their surroundings. Dried sludge can be used with waste incineration for power generation and achieve resource utilization.


2. Industrial Enterprises: Harmless Disposal of Industrial Sludge

Application scenes: chemical, printing&dyeing, food processing, pharmaceutical and other industrial enterprises can generate an average of 1-10 tons of industrial sludge per day (such as oily chemical sludge and printing&dyeing sludge).


Core Value: refer to the complex composition of industrial sludge (including heavy metals and organic matter), low-temperature drying ensures the harmful substances not to volatilize. Dried sludge meets hazardous waste disposal standards and can be safely entrusted to third parties for disposal or resource utilization (such as incineration of dried chemical sludge to recycle heat). The enclosed design prevents industrial sludge’s odor and harmful substance leakage to meet corporate environmental emission requirements.


3. Environmental Engineering Companies: Suiting Sludge Disposal Projects

Application scenes:environmental engineering companies,undertaking municipal and industrial sludge disposal projects,need to provide highly-efficient and environmentally friendly sludge drying equipment.


Core values: refer to rapid deployment of drying systems tailored to project,the modular design allows for flexible configuration can shorten project construction cycles. The machine's stable operation and simple repair can reduce project O&M costs for engineering companies. Its energy-efficient and environmentally friendly characteristics can promote project competitiveness and help engineering companies to get more sludge disposal orders.


With increasingly strict global environmental policies, sludge reduction, harmless treatment and resource recovery have already become core tasks for environmental governance in all countries. TENESUN's low-temperature sludge drying machine make "low-temperature drying, high-efficiency volume reduction and safe environmental protection” as its core technologies,overcoming the difficulties of high energy consumption, secondary pollution and unstable operation associated with traditional sludge disposal. It provides internationally leading solutions for sludge treatment in municipal and industrial sectors and has been successfully applied in multiple UN environmental projects.


Low-Temperature Drying Technology for Environmentally Friendly and Harmless Treatment

TENESUN's low-temperature sludge drying unit employs 50-80℃low-temperature drying technology. A closed-loop hot air circulation system heats and dries the sludge, preventing the volatilization of harmful substances (such as dioxins) during high-temperature drying process and eliminating secondary pollution at its source. This technology complies with EU RoHS environmental requirements. After drying, the sludge's heavy metal content and pathogen count meet the standards of "Urban Wastewater Treatment Plant Sludge Disposal - Agricultural Sludge" (GB4284-2018), making it safe to use in land improvement, building material production and other resource utilization scenes.


The machine's low-temperature drying process is highly energy-efficient: it uses air-source heat pump technology to obtain heat, saving over 70% more energy than traditional electric heating drying machine’s and over 40% more energy than gas-fired drying machine’s.The heat pump system recovers latent and sensible heat from the drying exhaust gas with a recovery efficiency of 85%, further reducing energy consumption. Taking municipal sludge with a processing capacity of 1 ton/day as an example,TENESUN low-temperature drying unit consumes only 150 kWh/ton of electricity during the drying process.But the traditional electric heating drying consumes 500 kWh/ton, saving RMB280 in electricity costs per day (calculated at RMB0.8/kWh).


For the Chifeng Green Hydrogen-Ammonia Project,TENESUN has customized design a linear low-temperature sludge drying unit for this world's largest hydrogen-ammonia project. With a rated water storage capacity of 400 kg per hour, it successfully treated the industrial sludge generated by the project, and the environmental performance of TENESUN's unit has received international authoritative recognition.
