Description
Technical field
The utility model relates to a kind of igniter and ignition method thereof of hydrogen chloride synthetic furnace, belongs to preparation of hydrogen chloride technical field.
Background technology
The synthetic operating mode of hydrogen chloride is extremely complicated, has severe corrosive.Hydrogen chloride synthetic furnace adopts manual firing's mode for a long time always.In the last few years, also have the automatic ignition device that adopts a kind of drive-in, when synthetic furnace need to be lighted a fire, arc ignition rifle pushes in stove by cylinder, after having lighted a fire, withdraws again, and this device has many defects:
First, owing to using cylinder, therefore need to provide cylinder stroke, therefore volume is larger, especially exposed outside synthetic furnace part volume very large, as shown in Figure 1, its volume is huge especially, and movement travel is long, inner side fire rod, air jet pipe, the measuring tube of pusher arc ignition rifle are movable, put fire later under the control of cylinder, must retreat to cut-off ball valve left side, whole stroke generally needs 650mm.The movement length of pusher arc ignition rifle has determined the size of pusher arc ignition rifle exterior arrangement cylinder, the stroke of cylinder must be greater than 650mm, so the total length of pusher arc ignition rifle is generally in 2000mm left and right, the part that is exposed to device external approaches 1200mm, so huge volume, outside cylinder must installation bracket, just can support the cylinder of pusher arc ignition rifle.
Second, the inner side fire rod of pusher arc ignition rifle, air jet pipe, measuring tube move in the time of burning under corrosion operating mode, when completing the backed off after random of igniting, etchant gas has been adsorbed on fire rod, air jet pipe, measuring tube, and retreat to adsorbed water under the environment of atmosphere and become diluted acid, in fact easier hot spot lighted torch, air jet pipe, measuring tube later; After exiting, must clean, could reduce corrosion, but increase greatly labour intensity.There is huge volume pusher arc ignition rifle outside, has corrosive gas around synthetic furnace, to the outside same very serious corrosion that produces of pusher arc ignition rifle.
The 3rd, existing hydrogen chloride synthetic furnace igniter, when igniting, it is abundant not that air and hydrogen often mix, and causes the success rate of igniting not high.
The 4th, existing hydrogen chloride synthetic furnace igniter, when igniting, the flame of arc ignition rifle head is often divergent shape, is easily dispelled by air-flow, thereby causes the success rate of igniting not high.
Summary of the invention
