FIELD: electrochemical industry; methods of baking of the graphitized electrodes, etc. ^ SUBSTANCE: the invention is pertaining to the method of baking of the products containing as the binding agent a resin or a pitch, for example, graphitized electrodes. The method of baking of the products containing as binding agent resin or a pitch, includes a pre-heating of the products by the gases outgoing from the baking chambers, the products baking and refrigeration, incineration of the fuel and a part of the escaping from the products pyrolized gases in the chambers of the baking, the products subjected to the baking are put in the containers combined in the blocks; all the escaping from the products pyrolized gases are withdrawn from each block of the containers as the separate stream, integrate the streams within the limits of each chamber into a common stream, which is withdrawn beyond the limits of the chamber, integrated with the streams from the other chambers and directed for incineration into the baking chamber, and in the containers maintain the pressure equal to or greater than the pressure in the corresponding chamber. The device includes the multichamber baking furnace with the burners to maintain the necessary temperature mode of baking and the tools for transportation of gases from the chambers of preliminary heating into the baking chamber and for transportation of the high-temperature gases from the baking chambers into the chambers of the preliminary heating. The chambers are supplied with the containers integrated in the blocks with the lids, which are linked to each other among themselves within the limits of the block by the branch-pipes for withdrawal of the pyrolized gases into the gas-collecting main located inside the chamber and connected with the branch-pipes for the gases withdrawal from the blocks of the lids and with the branch-pipe for removal of the pyrolized gases beyond the limits of the chamber. The branch-pipe is supplied with the tools to control the pressure inside the containers. At that the branch-pipes for withdrawal of the pyrolized gases from the separate chambers are connected with the outside located main, which is connected to tool used for delivery and incineration of the pyrolized gases in the baking chamber. The invention ensures the increase of the ecological and economical efficiency of the baking process in the multichamber baking furnaces. ^ EFFECT: the invention ensures the increase of the ecological and economical efficiency of the baking process in the multichamber baking furnaces. ^ 2 cl, 4 dwg, 1 ex |
