Abstract

The invention discloses a method and system for preventing coking gas from being exhausted abnormally. The method includes the following steps of real-time monitoring of electricity quality operation work conditions of key equipment of power supply and consumption systems and fault vent triggering, (2) protection of the key equipment, (3) voltage fluctuation suppression and harmonic wave isolation of the power supply and consumption systems, (4) safety interlocking and coordination control of the key equipment, and (5) uninterrupted non-impact dynamic switching of the key equipment, power supplies or circuits. The system is provided with a real-time monitoring and fault event triggering system, an equipment protection system, a voltage fluctuation suppression and harmonic wave isolation system, a key equipment safety interlocking and coordination control system and an uninterrupted non-impact dynamic state switching system. The systems work coordinately, and overall and comprehensive prevention of abnormal exhausting of coking gas is achieved. Compared with the prior art, abnormal exhausting of the gas is prevented, the utilization efficiency of electricity can be improved, loss is reduced, energy is saved, voltage quality is improved, and the coking safety production level and production efficiency are improved.

Description

technical field [0001] The invention relates to the field of pollutant discharge control in high-pollution industries, in particular to a method and system for preventing and controlling abnormal discharge of coking gas. Background technique [0002] The coking industry is the basic industry in the industrial field. The products coke, tar, and gas it produce are used as raw materials for industrial production and play a pivotal role in economic and social development. Especially in the 21st century, my country's economy has entered a new period of rapid development. Due to the large demand for steel products, the metallurgical industry is booming, and the coking industry is rapidly developing. The output of coke is doubled, and new coking plants are growing rapidly. However, the coking industry is also a high-energy-consuming and high-pollution industry. Its environmental problems involve air pollution, water pollution, soil pollution and noise pollution; it is a national k...
