In waste plastic pyrolysis production, carbon deposition in the furnace body and pipelines is a common phenomenon. Excessive carbon deposition affects heating efficiency and blocks pipelines, increasing equipment cleaning frequency and maintenance pressure. Optimizing the production process to reduce carbon deposition is key to lowering equipment maintenance difficulty and maintaining stable production capacity. By adjusting the furnace heat distribution method, material reaction rhythm and air circulation logic of the plastic refining equipment, Henan Yongle Group has developed a low carbon deposition production process to alleviate carbon accumulation and simplify daily equipment maintenance.

The plastic refining equipment adopts a production logic of uniform heat distribution and uniform-speed cracking to avoid local overheating of materials. In conventional equipment, excessively high local temperatures can easily cause material coking and agglomeration, forming thick carbon deposits, while a balanced furnace temperature environment allows materials to crack smoothly and reduces the formation of carbonized deposits.

The internal air circulation path of the equipment is well organized, removing fine suspended carbon particles in time during production and preventing them from adhering to the furnace wall and solidifying on the inner walls of pipelines. Continuous air flow keeps the internal structure of the equipment clean, slows down the accumulation of carbon deposits, and extends the cleaning cycle.

Reasonable negative pressure regulation allows materials to crack in a suitable vacuum environment, reducing excessive thermo-oxidation reactions and weakening the conditions for coking and carbon deposition. The standardized reaction atmosphere ensures full conversion of organic components into oil-gas resources, reducing ineffective carbon residue.

The low carbon deposition process effectively reduces the number of equipment shutdowns for cleaning and extends continuous production time. The plant no longer needs frequent furnace body grinding and pipeline dredging, saving maintenance labor and time costs and improving the overall efficiency of the production line.

Thanks to the mature low carbon deposition production process, the maintenance pressure of the plastic refining equipment is effectively relieved. The equipment can maintain good heating and ventilation conditions for a long time, with a slow rate of performance degradation. The worry-free maintenance and stable production support the efficient and orderly implementation of waste plastic resource recovery projects.
