During waste plastic pyrolysis, the output of oil-gas fluctuates slightly with material conditions and furnace temperature. Irregular gas generation can cause unstable pipeline pressure and insufficient condensation, affecting the entire production process. Adding an oil-gas buffer and pressure stabilization structure balances the gas generation rhythm and stabilizes downstream operating conditions, making the production process smoother. Based on the fluctuation patterns of pyrolysis gas generation, Henan Yongle Group configures a dedicated oil-gas buffer and pressure stabilization tank to organize the oil-gas transmission rhythm and ensure uniform and stable conditions for each process.

The plastic refining equipment is equipped with an independent oil-gas buffer tank. The mixed oil-gas produced by pyrolysis first enters the tank for temporary storage and buffering, preventing a large amount of oil-gas from instantly flooding into the condensation system during peak periods. Volume buffering weakens peak fluctuations in gas generation, keeping the oil-gas output flow even and continuous.

The tank interior features flow-dividing and flow-stabilizing structures that break up turbulent airflow and organize the oil-gas flow state, making the temperature and pressure of the oil-gas consistent before it is transported at a uniform speed to the condensation unit, providing favorable upstream conditions for uniform liquefaction and stable oil output.

A stable oil-gas transmission state reduces fluctuations in the operating conditions of the condensation system, avoiding uneven liquefaction and excessive moisture or impurities in the oil caused by irregular gas supply, keeping the quality of each batch of oil consistent.

The buffer tank effectively isolates the downstream purification system from fluctuations in furnace conditions, preventing mismatches in purification air volume caused by pressure surges, keeping the tail gas treatment process within the standard operating range, and ensuring stable environmental treatment results.

The configuration of the front-end pressure stabilization and buffering structure improves the condition regulation system of the plastic refining equipment, mitigates production impacts caused by material and process fluctuations, enhances the fault tolerance of equipment operation, and provides a stable process guarantee for normalized production in waste plastic resource recovery.
