Automatic ignition system of chlorine hydride synthesis furnace and control method of automatic ignition system

Abstract

The invention relates to an automatic ignition system of a chlorine hydride synthesis furnace and a control method of the automatic ignition system. The automatic ignition system comprises an ignition gun, a flame monitor, a chlorine inlet pipeline, a hydrogen inlet pipeline and a nitrogen inlet pipeline, wherein the ignition gun and the flame monitor are arranged on the side edges of the opening of the chlorine hydride synthesis furnace; the chlorine inlet pipeline, the hydrogen inlet pipeline and the nitrogen pipeline are simultaneously and parallelly connected in series with the bottom of the opening of the chlorine hydride synthesis furnace; the air inlet of the ignition gun is connected in series with an ignition air pipeline; the hydrogen inlet of the ignition gun is connected in series with an ignition hydrogen pipeline; and the input end of the ignition hydrogen pipeline is simultaneously connected with the those of the hydrogen inlet pipeline and the nitrogen inlet pipeline. The automatic ignition system provided by the invention has the advantages as follows the structure is compact; the operation is safe and reliable; the system doesn't need to be in direct contact with hydrogen when the furnace is ignited, can automatically detect and finish the whole ignition process so long as an ignition key is pressed, and thus is very safe and convenient.

Description

technical field [0001] The invention belongs to the field of hydrogen chloride preparation, and relates to an automatic ignition system of a hydrogen chloride synthesis furnace and a control method thereof. Background technique [0002] The working condition of hydrogen chloride synthesis is extremely complex and highly corrosive. The central flame of the combustion point of chlorine and hydrogen is about 2000 degrees Celsius, and it is accompanied by the corrosion of the burner device by the condensed hydrochloric acid medium. [0003] At present, an automatic ignition gun is used for igniting the hydrogen chloride synthesis furnace. When igniting, there is no ignition system and control method for the automatic ignition of the hydrogen chloride synthesis furnace. [0004] Therefore be badly in need of pressure method a kind of safe and reliable operation, the hydrogen chloride synthesis furnace auto-ignition system and its control method that ignition process realizes...
