Ignition device of hydrogen chloride synthetic furnace and ignition method thereof

Abstract

The invention relates to an ignition device of a hydrogen chloride synthetic furnace. The ignition device is characterized in that the ignition device comprises a tubular housing, the tubular housing is divided into an in-furnace segment and an out-furnace segment, the in-furnace segment and the out-furnace segment are connected through a flange, and an air connector is arranged on the out-furnace segment of the tubular housing; an electric arc ignitor, a gas pipe and a flame probe are arranged in parallel inside the tubular housing, the flame probe is longer than the gas pipe and the electric arc ignitor, and a thermocouple is installed on the head portion of the flame probe in a sheathed mode; the in-furnace segment of the tubular housing comprises a front sleeve and a rear sleeve, and the front sleeve and the rear sleeve are in threaded connection; a vortex board is arranged between the front sleeve and the rear sleeve in a pressed and fixed mode, the vortex board is of a circular shape, a hole is formed inside the vortex board, six to ten identical arc grooves are evenly distributed in the hole at the same angle, the cross section of each arc groove is formed by two arcs with different radii, the vortex board corresponds to a nozzle of the gas pipe in position, and a check ring is fixedly arranged on the inner wall, on the rear portion of the vortex board, of the front sleeve.

Description

technical field [0001] The invention relates to an ignition device for a hydrogen chloride synthesis furnace and an ignition method thereof, belonging to the technical field of hydrogen chloride preparation. Background technique [0002] The working condition of hydrogen chloride synthesis is extremely complex and highly corrosive. The hydrogen chloride synthesis furnace has been using artificial ignition for a long time. In recent years, a push-type automatic ignition device has also been used. When the synthesis furnace needs to be ignited, the arc ignition gun is pushed into the furnace through the cylinder, and then withdraws after the ignition is completed. This device has many defects: [0003] First of all, due to the use of the cylinder, the cylinder stroke needs to be provided, so the volume is relatively large, especially the part exposed outside the synthesis furnace is very large, as shown in the attached figure 1 As shown, its volume is particularly large, and...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved in the present invention is: the volume of the ignition device of the existing hydrogen chloride synthesis furnace adopts the structure of the cylinder propulsion type, which is bulky, and the cylinder must be equipped with a bracket, which has a complicated structure; it is easily corroded; when igniting, air and hydrogen often Insufficient mixing, the flame at the head of the arc ignition gun is easily blown away by the air flow, resulting in a low success rate of ignition
