Flue gas dispersion treatment device applied to tamping coal charging coke pusher and application method thereofTechnical Field
The invention relates to the technical field of metallurgical coking, in particular to a flue gas dispersion treatment device applied to a tamping coal charging coke pusher and a use method thereof.
Background
With sustainable development of countries, comprehensive utilization of resources by countries is increasingly important. The tamping coking blending coal can be matched with a certain amount of inferior coal to replace high-quality coal coking, so the tamping coking cost is low, and the quality of coke can be improved under the condition of equal blending coal. Tamping coke oven machinery is currently the dominant product of domestic coking equipment.
The tamping coal charging coke pusher (SCP integrated machine for short) is a large-scale integrated tamping coke oven machine, has the functions of tamping, coke pushing and coal charging, and has high automation degree and high working efficiency, but has the defects in environmental protection, and the following problems can occur in the working process:
1. when the side furnace door of the coke oven is opened and the furnace door is cleaned, tar is stuck on the furnace door and is Wen Maoyan in height;
2. during the coke pushing process, high-temperature flue gas in the furnace overflows in a large amount due to the opening of the machine side furnace door;
3. during the coal charging process, the coal cake enters the carbonization chamber to generate a large amount of raw gas, and during the raw gas flows out of the carbonization chamber, a large amount of smoke dust overflows;
and 4, the SCP all-in-one machine is opened at a machine side furnace door in the process of moving from a coke pushing position to a coal charging position (the coal charging position moves to the coke pushing position), and a large amount of flue gas in the furnace overflows.
5. In the coal charging process, the phenomenon of coal cake collapse is unavoidable, and a vehicle-mounted coal cake cutter is required to cut the collapsed coal cake, and then the furnace door is closed. When the coal cake is cut, the coal is baked at high temperature in the furnace, and a large amount of smoke dust is emitted.
A great amount of smoke dust can be generated in the above 5 processes, and the smoke dust problem is not well solved in the prior art. The smoke dust control of the machine side furnace door opening is always an important factor for restricting the development of the tamping coke oven in the working process of the tamping coal charging coke pusher.
At present, the smoke dust from the side furnace mouth passes through or is provided with a sealing frame device at the position of the coal charging mouth, a furnace door smoke collecting device is arranged above each furnace mouth, the smoke dust is controlled by the negative pressure in the furnace to return to the furnace to be converged with the smoke dust in the coke oven, and then is discharged through a smoke discharging guide sleeve. In the actual production process, the smoke dust control mode can only solve the smoke dust problem in the coal charging process, but cannot solve the smoke dust problem in the steps of coal charging, door cleaning, car moving and coal cake cutting. And the external natural wind can influence the effect of collecting the smoke at the furnace mouth.
The main components of the smoke dust generated in the coal charging process are raw gas (about 200 ℃), tar, spark and the like. The flue gas generated in the coke pushing process is mainly high-temperature air in the carbonization chamber, and deflagration is easy to occur during mixing if a dust removing system is used for the flue gas and the high-temperature air.
