Efficient integrated tar residue discharging system

Abstract

The invention relates to an efficient integrated tar residue discharging system, and belongs to the technical field of tar residue discharging devices in coking industry. The technical scheme includesthat a plurality of residue scraping tanks (1) corresponds to a tar residue transportation hopper (10), residue discharging pipes (2) of the residue scraping tanks (1) are connected on a feeding port(41) of a residue scraping machine (4), a discharging port (42) of the residue scraping machine (4) is connected with a closed tar residue bin (6), the closed tar residue bin (6) is provided with a residue bin discharging pipe (7), a liquid level meter (8) and an electric residue discharging valve (9), the tar residue transportation hopper (10) is arranged on the lower portion of the electric residue discharging valve (9), residue scraping tank discharging pipes (3) and the residue bin discharging pipe (7) are connected on an exhaust pipeline (11), and the exhaust pipeline (11) is connected with an oil washing tower (13) through an exhaust induced draft fan (12). The system has the advantages that a plurality of residue scraping tanks correspond to one tar residue transportation hopper, residue discharging efficiency is improved, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to a high-efficiency integrated tar slag discharge system, which belongs to the technical field of tar slag discharge equipment for slag scraping tanks in the coking industry. Background technique [0002] In the process of coking production, tar slag discharge plays an important role in the process of tar ammonia water separation system, and the smoothness of tar slag discharge directly affects the working efficiency of mechanical scraping tank. [0003] The traditional mechanized scraping trough slag discharge uses a tar slag removal hopper for each slag scraper trough, manual discharge, and multiple tar slag removal hoppers are reversed, which affects the working environment. The slag discharge method is rough and inefficient, and the tail gas generated during the slag discharge process directly escapes, causing environmental pollution. Therefore, it is necessary to improve the slag discharge method of the traditional mechanize...
