The Main Equipment for Activated Carbon Manufacturing-Activation Furnace

The current commonly used activation furnaces in China are:

(1) Slep furnace: also known as the saddle type furnace, because the refractory brick of the activation zone is a saddle type, which was originally a French patent. It was introduced into China by the Soviet Union in the 1950s and was put into production at the Taiyuan Xinhua Chemical Plant in Shanxi A series of improvements in the Beijing Guanghua Timber Factory have resulted in a small, simplified, small investment, and quick-recovery improved Slip-type activation furnace, which is used by many activated carbon factories to produce granular carbon. Our company sells carbonization furnace.

Activated gas: Alternate activation of water vapor and flue gas. Main advantages: continuous production, large output, high quality, high superheated steam temperature, stability, and no need for external heating. Main problems: high requirements for raw materials, high cost, high technical requirements, and large maintenance costs.

(2) Stewing furnace:

Activated gas: high temperature flue gas produced by coal combustion. Main advantages: simple and economical. Main problems: high fuel consumption, uneven activation, high labor intensity, and large dust.

(3) Soil harrow furnace:

Activated gas: water vapor (air). Main advantage: The simplest furnace type. Main problems: low yield, low quality, original workshop style, and environmental pollution.

(4) Multi-tube furnace:

Activated gas: water vapor. Main advantages: no fuel, stable, easy to control, and large output. Main problems: uneven activation, low carbon quality, low superheated steam temperature, easy damage to refractory tubes, and large investment

(5) Rotary furnace:

Activated gas: flue gas, water vapor. Main advantages: continuous operation, more uniform activation, suitable for production of gas-phase activated carbon. Main problems: huge equipment, poor thermal efficiency, fuel consumption, and low quality of finished products.

(6) Boiling furnace:

Activated gas: air, water vapor. Main advantages: good gas-solid contact, uniform activation, and small mechanical footprint. Main question: Asking about production, easy slagging affects normal operation and fuel consumption.

(7) Multi-layer rake furnace:

Activated gas: flue gas, water vapor. Main advantages: the introduction of fire-type equipment from abroad, large activation intensity, adaptability to various products, and automation. Main problems: large investment, high technical requirements, and high operating costs.

In addition, there are multi-tube boiling furnaces, overflow-type boiling furnaces, swirling jet activation furnaces, tunnel kiln activation furnaces, inclined plate activation furnaces, louver activation furnaces, mechanical rake activation furnaces, etc.
