1) conducting device is arranged on coke guiding locomotive top, utilizes the support that stretches out on the furnace stay to fix, compact in design, thereby save burnt platform top land the large-scale pipeline support, saved the consumption of steel, thereby reduced cost, improved the performance of enterprises.
2) docking facilities is positioned at directly over the coke guiding locomotive, has reduced the load of the 3rd rail, makes the scheme of cancellation the 3rd rail can be easy to realize.
3) the hot flue gas that rises directly enters smoke guide connector directly over it by large-scale air-suction cover, flows to smooth and easyly, and the control of flue gas is effective.
4) the burner smoke dust sucting point need not to arrange the power-assisted blower fan and has saved investment and reduced energy consumption near docking port.
5) a whole set of valve group is included in conducting device inside, and a whole set of conducting device greatly reduces than conventional lateral connected type pipeline valve group weight.
6) utilization of a whole set of valve group is located at unlatching docking facilities realization valve plate unlatching and the conducting on the large-scale air-suction cover of coke guiding locomotive top, and close valve and lean on the valve plate deadweight to finish, transmission rig and the easy-abrasion part of nothing complexity, open and close are reliable, Non-energy-consumption.
7) valve plate and valve base chamber adopt the sphere metal hard-sealing, and air leak rate of air curtain is low.Save the invest and operating cost of dedusting terrestrial station.
