Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific preferred embodiments.
In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, "first", "second" and the like do not indicate the degree of importance of the component parts, and thus, are not to be construed as limiting the present invention. The specific dimensions used in the present embodiment are only for illustrating the technical solution, and do not limit the protection scope of the present invention.
As shown in figure 1, the device for treating the furnace end smoke on the coke side of the coke oven comprises a conical smoke hood 40, a branch pipe 50, a draft pipe 60, a dust collection main pipe 70 and a ground dust treatment device 80.
The coke oven has a coke guide 10, a plurality of coking chambers, a plurality of combustion chambers, and a coke oven controller 20.
In fig. 1, 110 carbonization chambers are listed. The coke oven controller is connected with each carbonization chamber and each combustion chamber, and the coke oven controller is a computer or a remote client and the like, and belongs to the prior art. In the application, the coke oven controller adopts a three-car interlocking control system of the coke oven, and the model is Siemens S7-300. The coke oven three-vehicle interlocking control system can be one, all the coking chambers are connected with one coke oven three-vehicle interlocking control system together, or two or more coke ovens can be used, for example, two adjacent coke ovens form a group, one coke oven three-vehicle interlocking control system is shared, and the coke oven three-vehicle interlocking control system is connected with two pneumatic valves and a variable frequency fan in the group. The coke oven three-car interlocking control system can automatically judge a discharge (door removal or coke discharge) signal to the pneumatic valve and the variable frequency fan.
Each carbonization chamber is provided with a carbonization chamber furnace door 30, a conical smoke hood is arranged at the height h above each carbonization chamber furnace door, h is not more than 1m, and the preferable range is 0.4-0.8 m. The arrangement of 0.4-0.8 m can completely absorb the inorganically discharged flue gas generated when the coke side of the coke oven is subjected to door picking and coke pushing, and the normal production operation of the carbonization chamber is not influenced.
The top end of the gathering port of each conical smoke hood is provided with a branch pipe 50, and an automatic valve is arranged in each branch pipe, preferably the automatic valve is a pneumatic valve 51, and can also be an electric valve. Each automatic valve is connected with a coke oven controller.
Because the flue gas temperature of the coke side of the coke oven is more than 200 ℃, the tetrafluoro material is selected to seal the pneumatic valve.
The top of every branch pipe all sets up an curved honeycomb duct 60, the setting of honeycomb duct for resistance and frictional force when reducing the flue gas and flowing, more energy-conserving and reduce the wearing and tearing of pipeline corner.
The dust collection main pipe is horizontally arranged above the flow guide pipe and is communicated with the top end of each flow guide pipe. The middle part of the dust collecting main pipe is connected with a ground dust treatment device through a dust removing pipeline.
The ground dust treatment device comprises a variable frequency fan 81 connected with a coke oven controller.
The outer diameter of the dust collection main pipe is preferably DN 400-DN 600mm, and the use requirement can be met. Suction (or negative pressure) in the dust collection main pipe is controlled to be 700-1000 Pa, and the balance valve is preferably arranged on the dust collection main pipe and used for protecting the variable frequency fan and preventing overlarge negative pressure.
Furthermore, the ground dust treatment device uses the installed equipment of the existing coke oven, in addition, the dust collection main pipe is preferably positioned below the coal dust removal pipeline of the existing coke oven, and the dust collection main pipe can be connected with the existing coal dust removal pipeline through a shorter dust removal pipeline, so that the change of the existing equipment is small, and the occupied space is not occupied.
When one or more carbonization chambers are used for door picking or coke pushing, the coke oven controller receives a door picking or coke pushing starting signal, then opens the automatic valve corresponding to the door picking or coke pushing instruction, and simultaneously instructs the ground dust treatment device to be opened, and enables the variable frequency fan in the ground dust treatment device to be operated at a set high speed. The conical smoke hood can completely absorb the inorganically discharged smoke generated when the coke side of the coke oven is subjected to door picking and coke pushing, and the normal production operation of the carbonization chamber is not influenced. Furnace end cigarette after toper petticoat pipe absorbs gets into the collection dirt main pipe through corresponding branch pipe and honeycomb duct, gets into ground dust treatment device through the dust removal pipeline again and handles to accomplish the emission up to standard of organizing. When receiving a door-removing or coke-pushing ending signal, the coke oven controller instructs the variable frequency fan to operate for a period of time at a set low speed, then closes the variable frequency fan, and finally closes the automatic valve, so as to achieve the purpose of energy conservation.
The coke oven controller receives the door-off or coke-pushing start or end signal, which is the prior art, and comprises the following receiving modes: 1. manually pressing a start or end button; 2. setting a starting time or an ending time in a coke oven controller, and judging through the time; 3. the coke oven three-car interlocking control system can automatically judge a discharge (door removal or coke discharge) signal to the pneumatic valve and the variable frequency fan.
