This invention relates to the field of
coal gas purification technology, and more particularly to a method for controlling the resistance of a negative pressure
coal gas
system. This invention involves systematic technical analysis and
research based on theory and production practice, avoiding the need for post-
processing cleaning of the primary cooler,
electrostatic precipitator, and gas pipelines. It breaks through the methods and approaches for controlling and handling the resistance of negative pressure
coal gas systems involved in the field of
coal gas purification, employing daily monitoring and operational control of process parameters for the negative pressure
coal gas system, daily resistance prediction and process cleaning of the negative pressure
coal gas system, and
emergency response plans and procedures for the negative pressure coal gas system. This system, applied to negative pressure coal gas systems in coal gas purification, can maintain the long-term stability of the negative pressure coal gas system's resistance,
safeguarding production. This invention integrates daily control, resistance prediction, advance cleaning operations, and online cleaning operations, maintaining the long-term stable operation of the negative pressure coal gas system's resistance.
