GZ-LX Continuous Steam Activation Rotary Furnace Porous Carbon Preparation Special High Temperature Heat Treatment Equipment

Description :

  The GZ-LX continuous steam activation rotary furnace is a core industrial equipment specifically designed for high-temperature activation treatment of biomass charcoal or coal based charcoal. This equipment mainly solves the problems of low production efficiency, high energy consumption, and uneven activation in traditional intermittent furnaces. Through continuous feeding and discharging, it achieves large-scale industrial production. Under typical operating conditions, the material continuously flips inside the furnace as the cylinder rotates, coming into full contact with the incoming high-temperature steam and undergoing physical and chemical reactions to form a developed pore structure. This GZ-LX continuous steam activation rotary furnace is a key process equipment for improving key indicators such as product iodine value and specific surface area, and can meet the high-efficiency continuous operation requirements under environmental protection requirements.

1、 Working principle

Main reaction: C+H ₂ O (g) → CO+H ₂ (endothermic, 800-950 ℃)

The material is continuously fed from the high-end, the furnace body tilts and rotates at low speed, and the inner wall of the plate is rolled forward with animal material.

High temperature superheated steam (500-1000 ℃) is uniformly sprayed into multiple points, fully contacting and activating the material; After activation, discharge from the lower end and cool without oxygen to prevent oxidation.

The entire process is continuous, with production capacity several times that of intermittent production, lower energy consumption, and more stable quality.

2、 Equipment structure (core components)

Feeding system: Sealed quantitative feeding (such as coconut shell charcoal, coal charcoal, biomass charcoal), preventing air leakage and oxidation.

Rotary furnace body: heat-resistant alloy steel/refractory brick lining, inclined installation; Variable frequency drive, adjustable speed; Inner wall spiral plate strengthening material dispersion and residence time control.

Heating system: external electric heating/gas heating, temperature control accuracy ± 1 ℃, precise temperature control between 800-950 ℃.

Steam supply system: steam generator+superheater, producing 500-1000 ℃ superheated steam, with multiple nozzles evenly distributed and adjustable flow/pressure.

Atmosphere and exhaust treatment: maintain a slightly positive pressure inert/reducing atmosphere; Recycling CO and H ₂ combustible exhaust gases, utilizing waste heat or environmentally friendly combustion treatment.

Discharge cooling system: Oxygen free sealed cooling (water-cooled/air-cooled) to prevent reignition and secondary oxidation of activated materials.

Intelligent control system: PLC+touch screen, real-time monitoring of temperature, pressure, speed, steam flow, parameter linkage, quality fluctuation ≤ 5%.

3、 Core advantages

Continuous efficiency: Single furnace can produce 300-500 tons per year, and multi furnace linkage can reach over 1000 tons per year.

Quality controllable: precise temperature/steam control, uniform pore structure, good batch stability.

Widely applicable: Suitable for coconut shell, coal, biomass, resin based and other carbon materials, with customizable microporous/mesoporous distribution.

Energy saving and environmental protection: tail gas waste heat recovery reduces energy consumption by more than 30% compared to intermittent furnaces; Sealed design, dust/exhaust emissions meet standards.

4、 Typical application scenarios

New energy: Silicon carbon negative electrode porous carbon, supercapacitor carbon, battery electrode carbon.
