Description
Technical Field
The invention relates to the technical field of metallurgical coking, in particular to a flue gas centralized 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, coal charging and the like, has high automation degree and working efficiency, but has the defect of environmental protection, and the prior art cannot collect smoke dust well. The following problems occur during 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 coke pushing, door cleaning, car moving and coal cake cutting processes, and the collection effect of the smoke dust at the furnace mouth can be influenced by external natural wind.
Disclosure of Invention
The tamping coal charging coke pusher is a large-scale integrated tamping coke oven machine, and has the functions of tamping, coke pushing and coal charging. When the furnace door is taken down for cleaning operation, the taken down furnace door is stained with tar and emits smoke dust; during the coke pushing process, a large amount of smoke dust in the carbonization chamber overflows in a large amount from the opened furnace door hole; when the coal charging operation is carried out, the gap between the charged coal cake and the furnace walls at two sides of the carbonization chamber is about 10-20mm, the gap between the charged coal cake and the top of the carbonization chamber is about 200-300mm, and the generated smoke dust is ejected from the smoke outlet at the furnace top and the furnace side of the carbonization chamber through the gap between the coal cake and the two sides of the carbonization chamber; smoke dust at a furnace mouth moves from a coke pushing position to a coal charging position after coke pushing, and returns to the coke pushing position from the coal charging position after coal charging is finished; when the coal cake collapses and is cut, smoke dust is emitted from 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 coke pushing side wind shield and the coke pushing collecting cover also ensure that the external natural wind cannot influence the furnace front area; the smoke dust collecting pipeline of the cleaning door is in an open state; the coal-charging smoke dust collecting pipeline is in a closed state.
Pushing coke, loading coal and moving; after the coke pushing rod is retracted, the SCP integrated machine moves from a coke pushing position to a coal charging position, and when the movement starts, a valve plate of the coal charging pipeline is opened in a delayed manner to enable a coal charging smoke dust collecting pipeline to be unblocked; after the middle wind shield on the SCP integrated machine passes through the coke pushing hole, closing a valve plate of the coke pushing pipeline to close the coke pushing smoke dust collecting pipeline; the smoke dust collecting pipeline of the cleaning door is in an open state;

When the phenomenon of coal cake collapse occurs, the SCP integrated machine moves to the coal cake cutting position to cut the collapsed coal cake, and the valve plate of the coal charging pipeline is opened, so that the coal charging smoke dust collecting pipeline is unblocked. And opening a main collecting pipeline valve plate to enable the main smoke collecting pipeline to be connected with a ground dust removing pipeline, opening a coal cutting cake dust removing port above the coal cutting cake machine, and collecting smoke emitted from the furnace port. The smoke overflowed from the open furnace mouth is controlled in the area surrounded by the side wind shield of the coal cutting cake machine, the wind shield of the coal charging side and the coal charging smoke collecting pipeline at the upper part of the furnace mouth, so that the smoke is prevented from overflowing, and the suction can be effectively performed. After the coal cake cutting machine 13 finishes working, the SCP integrated machine moves from the coal cake cutting position to the coke pushing position, and when the movement starts, the valve plate of the coke pushing pipeline is opened in a delayed manner to enable the coke pushing smoke dust collecting pipeline to be smooth. After the middle wind shield on the SCP integrated machine passes through the coke pushing hole, the valve plate of the coal charging pipeline is closed to close the coal charging smoke dust collecting pipeline.
