Abstract

The invention relates to a negative pressure auto-ignition method for a hydrogen chloride synthesizing furnace. The negative pressure auto-ignition method is characterized by comprising the following steps: calling a nitrogen purging program by a computer: starting nitrogen purging, collecting nitrogen pressure data up to a set value, and starting a timer for timing till a set time; calling a nitrogen purging stopping program by the computer: turning off nitrogen purging; delaying for a certain time; calling an air controlling program by the computer: opening an air valve, and injecting air into the furnace; calling an igniting gun program by the computer: igniting by using the igniting gun, collecting temperature data and ultraviolet data detected from flame of the igniting gun till the temperature data and / or ultraviolet data reach / reaches set values / value; and calling a central flame controlling program by the computer: opening a central small flame hydrogen valve and a central small flame chlorine valve, filling quantitative hydrogen and chlorine into the furnace in proportion, delaying for a certain time, and opening a central flame hydrogen valve and a central flame chlorine valve, and further filling quantitative hydrogen and chlorine into the furnace in proportion.

Description

technical field

[0001] The invention relates to a negative pressure and positive pressure automatic ignition method for a hydrogen chloride synthesis furnace, belonging to the technical field of chemical production automation control. Background technique

[0002] The hydrogen chloride synthesis furnace is a specific object in chemical production. It needs a gradual process from starting ignition to putting into process control. The working conditions of the object are extremely complicated, the state measurement is difficult, and the control identification is vague. Therefore, the automatic ignition technology of hydrogen chloride synthesis furnace is a comprehensive technology that integrates processes, measurement technology, computer data acquisition and calculation.

[0003] The automatic control of hydrogen chloride synthesis furnace has always been a blank in this field. How to realize automatic control from ignition to normal process after one-button start is an unso...
