Further, the electric appliance controller is located in the control room.

Further, the electric appliance controller is electrically connected with the control room switchboard.

This neotype beneficial effect: provides a coke oven main flue water collecting system. And arranging the water collecting well of the main flue at the end part of the branch flue of the basement of the coke oven. And fixed drainage equipment and drainage pipelines are arranged in the smoke-dividing channel water collecting well. Automatic drainage is realized through the electric controller and the liquid level sensor, the personnel on duty is not needed, the drainage time and the labor are saved, the production efficiency is improved, and the service life of the flue and the total flue turning plate is prolonged. And the coke oven basement water collecting well is communicated with the bottom of the branch flue water collecting well, and because the coke oven basement water collecting well is shallower than the water collecting well of the branch flue, water in the coke oven basement water collecting well automatically flows into the water collecting well of the branch flue through an inclined pipeline, so that the maintenance of the basement water collecting well is reduced.
