AI Technical Summary
In existing technologies for coal tar residue filtration and recovery, the dilution control of coal tar in the pretreatment stage relies on experience or fixed parameters, which leads to unstable preheating effect, affects filtration efficiency, and makes it difficult to accurately control according to the real-time changes in the viscosity of the raw oil.
The device includes a recovery tank, a filtration mechanism, a preheating and conveying component, and a control decision module. It uses a data acquisition probe and a near-infrared online spectral probe to monitor the viscosity of coal tar and the oil content of filter residue in real time. The control decision module dynamically adjusts parameters such as preheating, negative pressure, and filtration time to form a closed-loop control and ensure the optimization of the filtration process.
It enables precise adjustment of preheating power and negative pressure intensity based on real-time viscosity, shortening the filtration cycle or increasing the throughput, improving oil-sludge separation efficiency, reducing oil loss in sludge, minimizing human error and production fluctuations, and ensuring stable operation of the unit.
