Tar slag separation recycling system

Abstract

The invention provides a tar slag separation recycling system which comprises a tar slag collecting groove, a first delivery pump, a centrifuge, a slag collecting groove, an oil and water collecting groove, a second delivery pump, an oil-water separator, a wastewater groove and an oil groove. Separation effect of tar slag with tar and water is improved due to high solid-liquid separation capability of the filter-type centrifuge, recycling rate of the tar slag and the tar is increased, and quality of the tar slag and the tar is improved. The tar slag and the tar which are separated can be utilized in production, and good environment-friendly benefit and social benefit are generated. The separation recycling system is automatic in feeding and discharging, simple in structure, easy to manufacture, few in personnel involved and easy to regulate and control.

Description

technical field [0001] The invention relates to the technical field of coking industry equipment, in particular to a tar residue separation and recovery system. Background technique [0002] The raw coal gas escaping from the coke oven is cooled by the gas collector and the primary cooler, and the high-boiling organic compounds are condensed to form coal tar. At the same time, the coal powder, semi-coke, graphite, ash and cleaning The porous substances brought in by the rising pipe and the gas collecting pipe are also mixed in the coal tar, forming agglomerates of various sizes, which are called tar slag. [0003] The output of tar slag is related to factors such as the moisture content of the incoming coal, the degree of crushing, and the instant of coal loading. Generally, tar residue accounts for 0.05% to 0.07% of the total weight of coking dry coal. Normally, the fixed carbon content in tar residue is about 60%, the volatile content is about 33%, the ash content is abo...

AI Technical Summary

Problems solved by technology

However, because the tar residue contains about 55% to 65% of tar and water, it is unevenly mixed with coal, it is very difficult to handle, and the environment is poor, so many enterprises cannot use it normally.
