Description
Technical field
Dry coke quenching equipment technical field is the utility model is related to, especially a kind of cold burnt discharge being used in dry quenching system
The rotation dump valve of equipment.
Background technology
, it is known that dry coke quenching is a kind of coke quenching method for coke wet quenching, refer specifically to use inert gas by red Jiao
A kind of method of cooling down.During dry coke quenching, the red burnt loading coke dry quenching furnace at the top of coke dry quenching furnace, cryogenic inert gas is by following
Ring blower fan is blasted in the red focus layer of coke dry quenching furnace cooling section, absorbs red burnt sensible heat, and the coke after cooling is discharged from coke dry quenching furnace bottom, from dry
Put out the high temperature inert gas that annular flue comes out and flow through coke dry quenching boiler progress heat exchange, coke dry quenching boiler is produced steam,
And the inert gas after cooling down is blasted coke dry quenching furnace by circulating fan again, inert gas recycles in the system of closing.It is dry
Quenching is better than coke wet quenching in energy-saving and environmental protection and improvement coke quality etc., is the energy-conserving and environment-protective technology that country encourages.
Dry quenching system mainly by red burnt load facility, cold burnt device for transferring, cycle equipment, coke dry quenching furnace and dry is put out
Burnt boiler plant etc. forms, wherein, the rotation dump valve for belonging to cold burnt device for transferring is arranged at coke dry quenching furnace outlet at bottom, rotation
Dump valve is a kind of multi-format rotary feeder with sealing property, can continuous discharge, there is good sealing again
And wearability, its effect for being arranged at coke dry quenching furnace outlet at bottom are the coke that vibra feeder is quantitatively discharged in air-tight state
Lower continuous discharge.During work, coke that vibra feeder is discharged, the entrance on spinning dump valve top is fallen into, by rotor
Rotation, discharged from the coke discharging mouth of bottom.Rotation dump valve can be fixed on a moveable chassis, spread along ground during maintenance
If track be pushed out to inspection platform.In order to improve sealing property, compensation can also be set by rotating the interface up and down of dump valve
Device.
However, it is existing rotation dump valve exist shortcomings and it is to be resolved the problem of, for example, in order to prevent dust from entering
Enter bearing housing, the both sides for rotating dump valve are required to be sealed, and existing sealing means are that end face seals firmly, and it is included mutually
