Background technique
The carbonaceous solids material such as coal, petroleum coke, rubbish passes through gasification production synthesis gas or fuel gas.Since these are carbon containing
Contain ash component in solid material, the slag produced after gasification is contacted with water, or the slag of production is contacted with water with the gases, so
Heel row goes out gasification furnace.Since gasification furnace is operated in the case where there is pressure, need that a dreg-locking hopper is arranged in gasification outlet of still to assist reality
Now continuous liquid slag discharging.Dreg-locking hopper periodical operation, when dreg-locking hopper collects slag, dreg-locking hopper and gasification furnace connection, pressure balance,
Slag flows into dreg-locking hopper from gasification furnace bottom；When dreg-locking hopper discharges slag, dreg-locking hopper and gasification furnace connection are cut off, dreg-locking hopper pressure release,
Dreg-locking hopper is discharged in slag together with water.
Continuous liquid slag discharging is one of key equipment of gasification installation.It is existing to be solved by the way of dreg-locking hopper
The deslagging problem of gasification furnace.But still there are many insufficient.Since dreg-locking hopper is arranged, while in the connecting tube of dreg-locking hopper and gasification furnace
Multiple tracks valve is set on the discharge pipe line of line and dreg-locking hopper in the vertical direction, increases the height of gasification installation, that is, increases
The investment of gasification installation；Dreg-locking hopper needs further with configuration lock hopper flushing water tank, the equipment groups such as Heisui River circulating pump at dreg-locking hopper
System, system complex, investment are high；Dreg-locking hopper is in the periodical operation between normal pressure identical as gasification furnace pressure, general half an hour
For an operation cycle, dreg-locking hopper is easy to produce metal fatigue, especially high-pressure gasified device；Pulp water in dreg-locking hopper need to come from
A large amount of water that lock hopper rinses water pot rinse, so that the pulp water of dreg-locking hopper need to consume a large amount of energy and be separated out, while water is also
Gasification installation use need to be returned.
Therefore, the overall investment of gasification installation is further decreased there is an urgent need to a kind of continuous liquid slag discharging device in practice,
Optimize the operation and consumption of gasification installation.
Utility model content
In view of the above problems, the purpose of this utility model is for the slag for the furnace slag discharge that gasifies in existing gasification installation
