Description
Technical field
The present invention relates to coking dedusting technology field more particularly to a kind of coordinated type of coke oven coke oven uprising tube lead fiery device and its
Working method.
Background technique
Coking industry is the important industry to concern the life-blood of the national economy, is quickly grown in recent years, but coking production is brought
Serious problem of environmental pollution is also outstanding day by day.During coke oven production, fire door, furnace roof are coaling the positions meeting such as hole, peephole
Loss flue dust, coaling, discharge of the coke etc. production links also can into atmosphere a large amount of paroxysmal pollutants of loss.It escapes in flue dust and includes
Surrounding enviroment are caused significant damage by the coal gas and a large amount of dust of tar-like substance.With country's constantly mentioning to environmental requirement
Height, the existing dedusting technology of coke oven have been difficult to meet the requirements, and only continue to develop advanced, energy saving, efficient environmental-protecting process ability
Actively promote the continual and steady sound development of coking industry.
Patent announcement number is that the Chinese patent of 107828430 A of CN discloses " a kind of dust excluding hood of coke oven ", is escaped for coke oven
Scattered flue dust is collected, handles, and is protected using refuge floor to dust excluding hood, refuge floor is made of engine firewall and anti-guncotton, energy
It is enough to protect dust excluding hood to a certain extent.But in the technical solution, dust excluding hood all closes at the top of coke oven, and tedge is also located
Within dust excluding hood, in coke oven production, when manhole cover is opened, the flame and high-temperature smoke that raw coke oven gas burning generates have temperature
Feature high, flame is long, and each coking cycles will appear.Moreover, manhole cover is forced sometimes under accident condition
It opens, a large amount of high-temperature smokes and raw coke oven gas will directly scorch the inside of dust excluding hood from coke oven coke oven uprising tube loss, with existing heat-insulated
Measure can not be effectively protected dust excluding hood, will cause dust excluding hood temperature distortion, or even burn.
Summary of the invention
The present invention provides a kind of coordinated types of coke oven coke oven uprising tube to lead fiery device and its working method, can be avoided tedge
The flame that middle raw coke oven gas burning generates scorches dust excluding hood of coke oven, and the high-temperature smoke of tedge loss under accident condition is exported coke
Outside furnace dust excluding hood, achieve the purpose that protect dust excluding hood of coke oven；Additionally by fuse primer can also counter force ventilation, prevent accident shape
