DOING® Brand Semi-Continuous Pyrolysis Equipment Models, Processing Flows, And Installation Details

If you are looking to scale up your waste-to-oil business but are hesitant about the high cost of fully continuous pyrolysis plants or the low efficiency of batch pyrolysis systems, DOING’s semi-continuous pyrolysis equipment is the solution you’ve been waiting for.

We have stripped away the complexity to focus on what matters most to your bottom line: Efficiency, Labor Savings, and Versatility.

1. Equipment Models and Capacity Reference

DOING semi-continuous pyrolysis equipment mainly offers the following standard models (customization is available based on customer raw material and site conditions).

2. Why Choose DOING Semi-Continuous Pyrolysis Equipment?

Many operators find themselves stuck: batch plants are too slow, and fully continuous plants are too demanding on raw materials. Our semi-continuous pyrolysis plant bridges this gap:

No More Waiting (High Efficiency): The biggest bottleneck in batch plants is the cooling time. Our semi-continuous system features high-temperature slag discharge. You don’t need to wait for the reactor to cool down; you can discharge carbon black immediately, saving 3-4 hours per cycle.

Lower Labor Costs: With automated screw conveyor feeding and sealed discharging, the entire process requires only 2-3 operators. It’s a significant upgrade from the manual labor required by batch systems.

Flexible Feedstock: Unlike fully continuous plants that require expensive, steel-free rubber powder, our system handles 16mm tire rubber powder, plastics, and oil sludge with ease.

3. The Processing Flow: How It Works

Our process is engineered for safety, speed, and environmental compliance:

Automated Feeding: Materials are fed into the reactor via a sealed screw conveyor, ensuring an anaerobic environment and preventing gas leakage.

Thermo-cracking: The reactor is heated directly by fuel oil, natural gas, or recycled syngas. Under high temperatures, waste is cracked into oil gas.

Condensation: The oil gas passes through a multi-stage tube condenser system, converting it into high-quality fuel oil.

Continuous Carbon Black Discharge: The highlight of this system is the combination of small reactor and screw discharger. It extracts carbon black continuously while the reactor is still hot, eliminating downtime.

4. Installation Made Easy

We know that installation is a major concern. At Henan DOING®  Company, a reliable and global-leading pyrolysis equipment manufacturer, we don’t just sell you a machine; we provide a complete solution:

Clear Guidance: Every shipment includes a comprehensive installation manual.

Foundation Support: We provide detailed civil engineering drawings to ensure your site is ready for the reactor.

Environmental Compliance: Henan DOING company's advanced waste gas and wastewater purification systems, include denitrification towers, desulfurization towers, pulse or wet electrostatic precipitators, and photo-oxidation/activated carbon waste gas treatment equipment. These systems reduce pollutants such as sulfur oxides (SOx), nitrogen oxides (NOx), volatile organic compounds (VOCs), and particulate matter (dust), thereby ensuring that final gas emissions meet relevant environmental assessment standards.
