Smoke-gas treatment system in production and pouring process of submerged arc furnace

The invention relates to a smoke-gas treatment system in a production and pouring process of a submerged arc furnace. The smoke-gas treatment system comprises a plant building, two side walls of the plant building are respectively provided with a window, the window comprises a window frame and flat blades which are installed on the window frame and used for being opened or closed, the plant building is also provided with a controller which is used for detecting a smoke-gas concentration in the plant building and controlling a driving mechanism to run according to the concentration of the smokegas, and the driving mechanism controls the opening degree of the blades according to an instruction of the controller; the opening and closing of the window are intelligently controlled by the controller, so that the air circulation and lighting in the plant building can be effectively ensured, and the high-temperature smoke gas in the plant building can also be ensured not to pollute the environment outside the plant building; by adopting a servo motor, the window can be ensured to be opened and closed accurately; and the circumferential movement is converted into the linear movement by utilizing a screw rod and a sliding block structure, so that compared with a hydraulic cylinder and air cylinder, the smoke-gas treatment system is practical and simple in structure; and a linkage combined structure of a first linkage, a second linkage, a third linkage and a connecting plate can realize the synchronous rotation of a plurality of blades, and the structure is simple and flexible.
