ZK Coal-Chemical Decanter - CM Series

Product catalog summary

Oily Sludge Treatment Overview
The document discusses the treatment of oily sludge, particularly in the coal chemical industry, which involves converting coal into various fuels and chemicals through processes like gasification, liquefaction, and tar processing. The focus is on the treatment of coal tar, a byproduct of coal dry distillation, which is categorized based on coking temperatures into high, medium, and low-temperature tars.

Coal Tar Industry
Coal tar is a viscous liquid with a pungent odor, produced during coal dry distillation. It is classified by pyrolysis temperature and contains significant water content. The document outlines the process of recovering crude tar from coal gas, which involves ammonia sprinkling and condensation.

Oily Sludge Treatment System Diagram
The document includes a system diagram for treating oily sludge using a three-phase centrifuge. This centrifuge separates the heavy liquid phase using gravity or a centripetal pump, with options for fixed or adjustable liquid layers based on process conditions.

Technical Characteristics of Three-Phase Centrifuge
The centrifuge features a high-performance sealing structure to reduce gas overflow and environmental pollution. It uses wear-resistant materials to extend maintenance cycles and ensure continuous operation. The centrifuge achieves high separation efficiency, reducing particle size to 2 μm and optimizing liquid clarification and solid dryness.

Separation Performance
The centrifuge effectively separates coal tar, achieving an aqueous ammonia content of less than 2.5%, tar content of at least 97%, and solid content of less than 0.3%. The tar in aqueous ammonia post-separation is reduced to ≤ 4g/L, based on a coal tar temperature of 270°C.

Technical Parameters
The document provides technical parameters for the centrifuge, including capacity, bowl diameter, speed, and power requirements. It notes that capacity is influenced by material characteristics and that dimensions vary with the liquid discharge method.
