Stove.
Background technology
Acetylene pyrolysis furnace is the nucleus equipment of gas by partial oxidation of natural legal system acetylene.Natural gas and oxygen are first respectively by pre-
Then hot stove heat respectively enters acetylene pyrolysis furnace blender and quickly mixes to 650 DEG C or so.Then mixed gas passes through burner
After the multiple mixing jet tubes of plate, lighted by igniter, occur oxidation and pyrolytic reaction in reative cell.Wherein about 60% natural gas
Occurs flame combustion with oxygen, while discharging substantial amounts of heat.About 30% natural gas splits under these heat conditions
Solution reaction, the natural gas that there is also about 5% is not engaged in reaction, but to be present in the form of methane in last cracking gas.This
The reaction of individual process is as follows：
Oxidation reaction：
Cracking reaction：2CH4→C2H2+3H2-Q (4)
Acetylene decomposition reacts：C2H2→2C+H2-Q (5)
The carbon black produced in this course of reaction a, part is discharged with cracking gas, a part of then to stick to burner plate anti-
Answer in chamber interior walls, by the accumulation of certain time, the coke of reaction chamber wall aggregation causes reaction chamber volume to diminish, and so then changes
Become the residence time of gas, have impact on reaction effect.The attached of charcoal device cleaning reaction chamber wall is scraped so needing periodically to use
Thing.Cracked gas is discharged after the water cooling that two layers of ring-type sparge pipe quenching device sprays up and down from the lower house side mouth of pipe,
And sooty water is then discharged from lower house bottom.

It is also easy to damage equipment, it is desirable to realize that the function of automatic scraping charcoal is also more difficult.The acetylene pyrolysis furnace water quenching device for cooling point run at present
For three layers or one layer arrangement, due to shower nozzle number too much, injection diameter is too small to easily cause blocking to three layers of arrangement；One layer arrangement by
Excessively concentrated in water, cooling effect is poor.
So being highly desirable to improve existing acetylene pyrolysis furnace, processed to reduce the processing cost of equipment and improve
