Description
Technical Field
The invention relates to the technical field of metallurgical coking, in particular to a smoke dispersion treatment device applied to a tamping coal-charging coke pusher and a use method thereof.
Background
With the sustainable development of the country, the country pays more and more attention to the comprehensive utilization of resources. A certain amount of low-quality coal can be mixed in the tamping coking coal blending to replace high-quality coal for coking, so that the tamping coal coking cost is low, and the quality of coke can be improved under the condition of the same coal blending. Tamping coke oven machinery is currently the mainstream 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 tamping, coke-charging and coal-charging functions, has high automatic degree and working efficiency, is deficient in environmental protection, and can generate the following problems in the working process:
1. the side door of the coke oven machine is opened, when the door is cleaned, tar is adhered on the door, and the tar is smoked due to high temperature;
2. during the coke pushing process, a large amount of high-temperature flue gas in the coke pushing furnace can overflow due to the opening of the furnace door at the machine side;
3. during the coal charging process, the coal cake enters the carbonization chamber to generate a large amount of raw gas, and during the process that the raw gas flows out of the carbonization chamber, a large amount of smoke dust overflows;
and 4, opening a machine side furnace door of the SCP all-in-one machine in the process of running from the coke pushing position to the coal charging position (running from the coal charging position to the coke pushing position), and enabling a large amount of smoke in the furnace to overflow.
5. In the coal charging process, the phenomenon of coal cake collapse is inevitable, a vehicle-mounted coal cake cutting machine 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 in the furnace at high temperature, and a large amount of smoke and dust are emitted.
The above 5 processes all produce a large amount of smoke and dust, and the prior art does not solve the smoke and dust problem well. The smoke dust treatment at the machine side oven door in the working process of the tamping coal-charging coke pusher is always an important factor for restricting the development of the tamping coke oven.
At the present stage, the smoke dust emitted from the furnace mouth of the machine side passes through or is provided with a sealing frame device at the coal charging mouth, a furnace door smoke collecting device is arranged above each furnace door mouth, and the smoke dust is controlled by the negative pressure in the furnace to return into the furnace and be collected with the smoke dust in the coke furnace, and then is discharged through a smoke discharging guide sleeve. In the actual production process, the smoke control mode can only solve the smoke problem in the coal charging process and cannot solve the smoke problem in the coal charging, door cleaning, vehicle moving and coal cake cutting processes. And the external natural wind can influence the smoke collecting effect at the furnace mouth.
The main components of the smoke generated in the coal charging process are raw gas (about 200 ℃), tar, sparks and the like. The flue gas generated in the coke pushing process is mainly high-temperature air in a carbonization chamber, and if the flue gas and the high-temperature air are used by one set of dust removal system, the flue gas and the high-temperature air are mixed to easily generate deflagration.

step six, closing the furnace door; the door taking device 10 conveys the furnace door back to a closed state from the position of the door cleaning to finish the action of closing the furnace door; closing the valve plate 2.2 of the coal charging pipeline and closing the coal charging smoke dust collecting pipeline 2; the in-vehicle dust collector 5 is in an open state.
Wherein, removable dress coal stove mouth cigarette collection cover 2.1 has the dismantlement function, when SCP all-in-one tamping machine needs the maintenance, can pull down removable dress coal stove mouth cigarette collection cover 2.1.
The vehicle-mounted dust remover 5 and the SCP all-in-one machine are detachably assembled.
When the coal cake collapses, the SCP all-in-one machine moves to the coal cake cutting position to cut the collapsed coal cake, the coal charging smoke dust collecting pipeline 2 is opened, the coal cake cutting dust removing opening 13.1 positioned above the coal cake cutting machine 13 is opened, and smoke dust emitted from the furnace opening is collected at the moment. The smoke dust overflowing from the open furnace mouth is controlled in the area enclosed by the coal cake cutting machine side wind shield 6.4, the coal charging side wind shield 6.3 and the coal charging smoke dust collecting pipeline 2 on the upper part of the furnace mouth, so that the smoke dust is prevented from overflowing and can be effectively sucked. After the coal cake cutting machine 13 finishes working, the SCP all-in-one machine 7 moves to a coke pushing position from a coal cake cutting position, and when the movement starts, the vehicle-mounted dust remover 5 is in an open state.
By adopting the technical scheme, the coal cake cutting dust removal port is positioned on the coal-charging smoke dust collection pipeline, and the coke pushing, door cleaning and coal-charging smoke dust collection pipeline is connected with the ground dust removal pipeline. The valve plates are added on the smoke dust collecting pipelines, the valve plates of the dust removing pipelines are opened/closed in a delayed mode, the air quantity is increased, the concentration of mixed gas is diluted, and the detonation condition of smoke dust with different components is avoided.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
