The continuous sludge carbonization plant employs a slow pyrolysis process to convert sludge into sludge biochar within a sealed environment, while simultaneously recovering syngas to provide self-sustaining heat. The biomass carbonization plant achieves sludge volume reduction, harmless treatment, and resource recovery.
Raw Materials
Municipal Sewage Sludge
Excess activated sludge generated from the biochemical treatment of urban domestic sewage. It has a high organic matter content and is the most commonly used feedstock for sludge carbonization projects. The organic matter consists primarily of microbial biomass and humus, making it suitable for pyrolysis-based carbonization to produce sludge biochar.
Municipal sewage sludge cannot be fed directly into the carbonization furnace. Dewatered sludge with a moisture content of 80% must first be dried to below 20% before entering the pyrolysis stage.
Industrial Organic Sludge
Sludge from the food, brewing, and papermaking industries: High organic matter and low heavy metal content. Pyrolysis and carbonization of these materials can yield high-quality biochar.
Sludge from printing and dyeing, chemical, and pharmaceutical wastewater: High organic matter content, but requires careful monitoring for heavy metals, persistent organic pollutants (POPs), and toxic contaminants.
Livestock and poultry manure digestate sludge: Classified as organic sludge. It is suitable for co-carbonization and offers high potential for carbon sequestration.

Sludge Carbonization

Continuous Biochar Production Process

Feedstock Pre-treatment
Raw sludge from wastewater treatment plants typically has a moisture content of around 80% and cannot be fed directly into the carbonization furnace. High moisture content drastically increases energy consumption for drying, consumes the furnace's thermal load, and can even lead to unstable pyrolysis temperatures.
Wastewater sludge generally requires mechanical dewatering, such as plate-and-frame filter pressing or belt press dewatering. Some projects incorporate a pre-drying unit to reduce the sludge cake to the target moisture content before it enters the continuous carbonization equipment.

Feedstock Conveying
Continuous and stable feeding is a crucial foundation for the steady operation of a continuous biomass pyrolysis plant.The dried material is transported via conveyor belt to the feeder.
Conveying equipment can continuously transport pre-treated feedstock to the carbonization zone. For industrial large scale biochar production projects, the uniformity of the feed directly affects the stability of the subsequent biomass carbonization process.

High-Temperature Continuous Carbonization
Once biomass feedstock enters the carbonization equipment, it undergoes pyrolysis and carbonization at a set temperature and residence time. Precisely controlling the pyrolysis and carbonization process ensures greater uniformity in the quality of the resulting biochar.
Biomass feedstocks vary in terms of moisture, density, ash, and volatile matter content. Consequently, operational parameters for the carbonization equipment must be adjusted based on the specific characteristics of the feedstock during actual production.

Biochar Cooling and Discharge
Biochar that has just undergone carbonization is typically at a high temperature. Therefore, after discharge, it requires cooling via an appropriate cooling and conveying system. The biochar then proceeds to subsequent stages such as storage, packaging, or further processing.
A well-designed cooling system not only facilitates the collection of the finished product but also enhances the safety of the entire production process.

Energy Recovery and Utilization
Syngas is generated during the biomass pyrolysis process. It first passes through a cyclone dust removal system for desulfurization and dust removal, then enters a condenser where it is separated into wood vinegar and tar. The remaining syngas is directed to the exterior of the main furnace to heat the carbonization reactor.
A portion of the waste heat flue gas can be used to heat the dryer. The remaining flue gas is discharged after passing through the dust removal system.
