1. Product Introduction
This equipment is a specialized rotary dryer designed for biomass gasifier feeding systems. It has a rated processing capacity of 240 tons per day and is mainly used for the dehydration and drying of raw materials such as gasifier-grade wood sawdust and fine wood powder.
The dryer can accurately reduce the moisture content of high-moisture sawdust to the standard level required by the gasifier feeding system, effectively solving problems such as feeding blockage, incomplete gasification, and low gas production efficiency caused by wet sawdust. It is a core raw material pretreatment equipment for biomass gasification power generation and heating projects.
2. Advantages & Features
1. Matching Gasifier Capacity
With a processing capacity of 240 tons per day, the dryer precisely matches the raw material consumption requirements of medium and large biomass gasifiers. It can provide 24-hour continuous and stable material supply, ensuring uninterrupted and efficient operation of the gasification system.
2. Improving Gasification Efficiency
The dryer adopts a precise temperature-controlled drying process, ensuring uniform and controllable moisture content of sawdust. After drying, the raw material has better air permeability and stable calorific value, significantly improving the gas production efficiency and gas purity of the gasifier while reducing raw material loss.
3. Optimized for Fine Sawdust Characteristics
According to the characteristics of sawdust, such as fine particles, easy scattering, and easy clumping, the internal airflow speed and lifting flight structure are optimized. This effectively reduces fine powder loss, disperses agglomerated materials, and prevents blockage at the feeding inlet.
4. Energy Saving, Durable & Easy Maintenance
The dryer can recover waste heat from gasifier exhaust gas as a drying heat source, achieving energy recycling and reducing operating costs. The machine body is manufactured with wear-resistant steel, featuring a low failure rate. The modular design makes daily maintenance and cleaning more convenient.
3. Working Principle
Wet sawdust is evenly fed into the rotary drum through the feeding device. Driven by the transmission system, the drum rotates at a low speed, while internal lifting flights continuously lift, scatter, and disperse the sawdust, forming a uniform material layer.
The waste heat hot air from the gasifier or the supplied hot air enters from one end of the drum and forms a counter-current contact with the sawdust. Through heat convection, moisture inside the raw material is rapidly evaporated.
The dried qualified sawdust is directly conveyed to the gasifier feeding system through the discharge device. Dust-containing exhaust gas is treated by the dust removal and purification system before being discharged according to environmental standards.
The entire process achieves fully automated and continuous operation, providing stable and high-quality raw materials for biomass gasification systems.
