Description
Technical field
The utility model is related to synthetic ammonia installation technical field, it is specifically related to anticlogging gas in a kind of Ammonia Production
Change fire grate water pipeline system.
Background technology
Synthetic ammonia gasification fire grate water generally has three tunnel whereabouts, be respectively be discharged into slag bath, go into operation cooler and hp flash drum.
Since synthetic ammonia gasification stove need to undergo draining switching twice to rising to normal production pressure feeding intake:Switch for the first time, gasification
Stove is before pressure is raised to 0.5Mpa after feeding intake successfully, and the water of gasification furnace is directly discharged into slag bath, when gasification furnace pressure rises to 0.5Mpa
Afterwards, the toxic and harmful gas to avoid high temperature buck and its inside from dissolving impacts environment and personnel, and gasification furnace is drained
It cuts toward the cooler that goes into operation and carries out cooling processing;Second of switching, after gasification furnace pressure is raised to 4.0MPa, for recovery system heat
Amount reduces solid content, a small amount of sour gas of parsing in Heisui River temperature, concentration Heisui River, it is necessary to the water for being discharged into the cooler that goes into operation
It is switched to hp flash drum.
Gasification furnace draining often will appear the problem of not draining when switching for second, thus seriously affect gasification furnace
And the normal operation of hp flash drum.Because three sets of gasification furnaces share a set of main sewer in normal production, it is standby to open one two
In system, wherein two gasification furnace long-term operations, can make spare gasification furnace drain main valve to this length of tubing of main sewer
For interior fluid for a long time in not flow regime, it is total to may result in back-up vaporization fire grate water for the operation once back-up vaporization stove is driven
Valve, due to the effect of expanding with heat and contract with cold, causes the dirty piece in pipeline to fall off to the pipeline between main sewer, the dirty piece that falls off and black
The fine ash deposited in water is easy in back-up vaporization stove to the flowing line between hp flash drum caking to blocking pipeline, into
And back-up vaporization stove is caused to be unable to operate normally.
Invention content
In order to solve the above technical problems, the utility model provides anticlogging gasification furnace draining in a kind of Ammonia Production
