Novel single-hole carbonization chamber pressure regulating system and regulating method

Abstract

The invention relates to a novel single-hole carbonization chamber pressure regulating system and a regulating method. An expansion pipe is arranged at the bottom end of a bridge pipe, and the outside of the expansion pipe is connected with a gas collecting pipe through a water seal seat; and a pressure regulating device is arranged inside the expansion pipe. The pressure regulating device comprises a fixed ring, a moving cup, an air cylinder, an air cylinder pull rod, a cross beam, an ammonia water nozzle and a pressure measuring device. The fixed ring is arranged at the bottom end of the bridge pipe, and the moving cup is arranged directly below the fixed ring; the air cylinder is arranged on the bridge pipe above the fixed ring, and a cylinder pull rod connected with a cylinder piston passes down through the fixed ring and is connected with the moving cup. The center of the bottom of the moving cup is provided with a drain hole which is closed by a valve seat. The bottom of the expansion pipe is provided with the cross beam, and the center of the cross beam is provided with a push rod which is matched with a drainage hole on the moving cup. The ammonia water nozzle and the pressure measuring device are respectively fixed on the top of the bridge pipe above the pressure regulating device, and the spraying range of the ammonia water nozzle covers the bottom of the bridge pipe. The single-hole carbonization chamber pressure regulating system has the advantages of simple structure, high adjusting sensitivity and long service life.

Description

technical field [0001] The invention relates to the technical field of coking, in particular to a novel single-hole carbonization chamber pressure regulating system and regulating method. Background technique [0002] The single-hole carbonization chamber pressure regulation technology is a technology developed to further reduce the discharge of pollutants during the coal charging and coking process of large-scale coke ovens. Inhalation of air due to the negative pressure of the carbonization chamber can not only reduce pollution emissions, but also improve coke quality, reduce furnace leakage, and increase the output and quality of tar and benzene in raw coal gas. [0003] At present, the relatively mature single-hole carbonization chamber pressure regulation systems include the PROVEN system in Germany, the SOPRECO system in Italy and the CPS system in China. Among them, the PROVEN system adjusts the raw gas flow section by adjusting the full flow level, and then adjusts ...
