The apparatus for removing sediments in a fume duct according to the present invention is a device for removing precipitates generated by extrusion of coke in a coke oven to generate deposited dust. The apparatus includes a sealing belt 110 on an open top surface, A fume duct (100); A moving unit 200 connected to the transfer car 40 to move the transfer car 40 integrally along the sealing belt 110 of the fume duct 100 when the transfer car 40 moves; And a removal unit 300 connected to the lower part of the mobile unit 200 and positioned inside the fume duct 100 and detecting precipitates deposited inside the fume duct 100 to spray the air to move the precipitate .

The fume duct 100 is a path through which fine dust and dust generated during the extrusion process of the gypsum coke are collected and conveyed to the hood E.C.S using the negative pressure. The upper surface is open and a sealing belt 110 covering the open upper surface is provided.

The removal unit 300 is a component for processing the precipitate in which fine dust, dust, etc. are stacked in the fume duct 100. And is moved together with the fume duct 100 when the transfer car 40 is moved. Also, since the fume duct 100 is located inside the fume duct 100, the fume duct 100 is designed to be able to treat the internal sediment.

The removal unit 300 moves along the inside of the fume duct 100, and when the deposited deposit is sensed, the air is sprayed to move the deposit. Preferably, the means for sensing the sediment is attached in front of the moving direction and the forward air jetting means 330 is formed in the rear direction so that the means for sensing the sediment, not always spraying the air, Only air is injected selectively. This makes it possible to reduce the energy used for spraying the EE.

Air is sprayed toward the front, thereby moving the sediment in the fume duct 100 along the moving direction of the mobile unit 200. The moved sediment is driven to a portion where the extension of the fume duct 100 ends.
