Technical Breakthroughs in Large Continuous Pyrolysis Equipment

The current solid waste treatment field is faced with multiple core challenges, such as the continuous rise in disposal costs, the huge environmental pressure caused by increasingly strict environmental protection standards, the waste of resources due to the ineffective recovery of valuable energy and materials in solid waste, and the efficiency and scale bottlenecks of traditional batch pyrolysis technology that are difficult to meet the requirements of large - scale continuous operations. Under this background, DOING's latest continuous pyrolysis technology, with its unique advantages, is becoming an ideal choice to address these challenges.

Key Technological Breakthroughs in Continuous Pyrolysis

The maturity, widespread adoption, and strong customer recognition of DOING’s large-scale continuous pyrolysis technology are attributed to breakthroughs in the following key areas:

1. Advanced Dynamic Sealing and Micro-Negative Pressure Oxygen Isolation

Achieving robust and reliable sealing in high-temperature, dynamic pyrolysis environments is arguably the most formidable challenge in continuous operations. Its successful mastery is what truly distinguishes a continuous system from its batch counterparts, preventing detrimental oxygen ingress, ensuring process safety, and maximizing valuable oil yield.

DOING, as a pioneering supplier of continuous pyrolysis plants, has successfully engineered a sophisticated solution to the sealing problem under high-temperature dynamic conditions. At the feeding end, a multi-layered defense system is employed, combining material sealing, mechanical sealing, and inert gas protection. For instance, a screw-type feeding device incorporates a specialized sealing structure for effective material blockage, complemented by precision mechanical seals to prevent gas leakage. Nitrogen is consistently introduced as an inert gas to form a protective atmosphere around the feeding port, creating an oxygen-free zone. At the discharging end, water-jacket-cooled screw conveyors provide additional safeguards.

By meticulously monitoring the internal furnace pressure in real-time via advanced pressure sensors, our system automatically adjusts the nitrogen flow rate and feeding speed. This ensures the consistent maintenance of a stable micro-negative pressure and an ultra-low oxygen environment within the furnace. This meticulous design eliminates oxygen ingress, which is critical for preventing secondary combustion and guaranteeing the production of high-quality, stable pyrolysis oil, free from harmful contaminants. By maintaining a precise micro-negative pressure, we guarantee unparalleled operational safety while maximizing the recovery of valuable liquid and gaseous fuels, translating directly into higher energy efficiency and enhanced profitability for our clients. This sophisticated sealing mechanism is also a cornerstone of our system’s environmental integrity, preventing harmful emissions and ensuring compliance with the most stringent global standards.

2. Precise Material Conveyance and Uniform Distribution

Consistent and uniform material feeding is the bedrock of stable pyrolysis kinetics and product homogeneity. Without it, efficiency plummets, and product quality fluctuates. Our system ensures that pre-treated materials (such as shredded waste tires, waste plastics, or oily sludge) are continuously, uniformly, and stably fed into the pyrolysis reactor through a precise automated feeding system. And the daily processing volume of DOING large continuous pyrolysis equipment can achieve 50TPD per set. This is the absolute prerequisite for ensuring the stability of the pyrolysis reaction and the consistency of product quality.

Furthermore, a specially designed material distributor is integrated at the feeding port. Its structure, resembling a spiral baffle, ensures that as material enters the furnace, it is evenly distributed. This design ensures that the material fully contacts the heat source and undergoes a uniform pyrolysis reaction. This precision not only ensures a steady and uninterrupted pyrolysis reaction but also guarantees optimal heat transfer throughout the feedstock, maximizing conversion rates and yielding consistently high-quality end products, whether it’s pyrolysis oil, carbon black, or syngas. The integrated material distributor further optimizes the process by preventing material clumping and ensuring uniform exposure to heat, leading to higher throughput and reduced energy consumption per ton of processed waste.

3. Intelligent Integrated Control

In today’s industrial landscape, intelligent control is paramount for optimizing performance, minimizing human error, and ensuring proactive system management. DOING’s proprietary PLC-based intelligent control system provides real-time, comprehensive oversight of every critical parameter – from temperature and pressure gradients across different reaction zones to oxygen levels and material flow rates.

The system’s adaptive algorithms automatically adjust heating power to maintain optimal temperatures, precisely regulate inert gas flow to ensure an oxygen-free environment, and fine-tune feeding rates for consistent throughput. For instance, if the temperature in a specific area deviates from the set range, the system automatically adjusts heating power. Should oxygen content rise, it swiftly increases nitrogen flow to restore inert conditions. Similarly, material flow rates are continuously monitored and adjusted to prevent bottlenecks or underfeeding.
