Abstract

The invention discloses a pressure stabilizing automatic regulating system of a coke oven gas collector and a regulating method thereof, and can stably control a coke oven gas export system. The pressure stabilizing automatic regulating system comprises a coal charging section electric control valve used for regulating pressure in a coal charging section gas collecting tube, a communication valveused for regulating pressure in a large circulation pipe, a first-stage computer system and a second-stage computer system, wherein the first-stage computer system comprises a DCS control system, a field sensor and an actuating mechanism and is used for realizing field level distributed control; the second-stage computer system regulates the opening of the coal charging section electric control valve and the opening of the communication valve according to the pressure in the coal charging section gas collecting tube.

Description

technical field [0001] The invention relates to the technical field of large coke oven coking, in particular to a coke oven gas collecting pipe pressure stabilization automatic adjustment system and a coke oven gas collection pipe pressure stabilization automatic adjustment method. Background technique [0002] Panzhihua Iron and Steel Xichang Steel Vanadium Co., Ltd. adopts DCS (Distributed Control System) control system for the coking 7-meter top-loading coke oven and 6.25 tamping coke oven gas collection pipe export control system. The DCS control system includes the coke oven DCS control system and the blower DCS control system. The coke oven DCS control system and the blower DCS control system are independent of each other, and both use ZKU SUPCON JX-300XP, and the systems have been networked. [0003] There are two control loops in the current system: one is to adjust the regulating valve of the air collecting pipe according to the pressure of the air collecting pipe; ...
