This invention discloses a method and system for synergistic regulation of low oil content and high-quality tar in circulating ammonia water of coking plants, belonging to the field of coal chemical tar ammonia water separation and purification technology. The system includes a gas-liquid separation device, a tar ammonia water separation device, a reagent quantitative dosing device, a tar residue draining device, and a control system. The gas-liquid separation device includes a gas-liquid separator, a horizontal tube primary cooler, an upper condensate circulation tank, and a lower condensate circulation tank. The tar ammonia water separation device includes a mechanized tar ammonia water separation tank, a first-stage circulating ammonia water tank, and a second-stage circulating ammonia water tank. The reagent quantitative dosing device includes a multi-point synergistic demulsifier dosing device and a flocculant dosing device. The tar residue draining device includes a liquefaction tank, a grinding pump, a centrifuge, and a slag hopper. The control system includes a hysteresis-stretching interface meter, an automatic regulating valve, and a PLC controller. This invention breaks through the traditional single-improvement mode, forming a systematic solution; it can significantly reduce the oil content of circulating ammonia water and improve tar quality.

The utility model discloses a kind of high-efficiency wet grinding pumps for rubber accelerator, comprising: base, filter assembly;Filter assembly includes fixedly installed grinding cylinder on base, the movable installation of cylinder cover in grinding cylinder side by multiple sets of screw, the installation port of the central portion of cylinder cover, the filter cartridge of movable installation in installation port inside.
