The invention relates to a flue gas switching pipeline. The flue gas switching pipeline comprises a shell; a flue gas outlet is connected with a flue gas exhaust pipe, a switching hole is formed in the side wall of the rear portion of the shell, the switching hole is in butt joint with a switching pipe, and the other end of the switching pipe is connected to the flue gas exhaust pipe; a partitionplate located on one side of the switching hole is fixedly arranged in the middle of the shell, and a rotating plate attached to one side of the partition plate is rotatably arranged on one side of the partition plate. Through holes corresponding to each other are formed in the partition plate and the rotating plate, and the edge of the rotating plate is provided with a blocking piece formed by extending towards the switching hole along the inner wall of the shell; the shell is provided with a control hole located in one side of the rotating plate, the rotating plate is further connected witha swing rod extending to the outer side of the shell through a control hole, the swing rod rotates in a reciprocating mode, and when the through holes in the rotating plate correspond to the through holes in the partition plate one to one, the blocking piece blocks the switching hole; and when the through holes in the rotating plate and the through holes in the partition plate are staggered, the blocking piece is staggered from the switching hole. According to the flue gas switching pipeline, pipeline switching is conducted on flue gas entering the rear portion of the shell through the partition plate, the rotating plate and the switching pipe.
Description
technical field [0001] The invention relates to a flue gas switching pipeline. Background technique [0002] Flue gas waste heat recovery technology installs a heat exchange device in the flue gas pipeline, and heat exchange occurs between the high-temperature flue gas and the heat exchange medium, so that the temperature of the flue gas decreases and the temperature of the heat exchange medium increases; due to the heat of the flue gas When the heat exchange is sufficient, its temperature drops rapidly, which leads to the fact that in some cases, the heat exchange process of the flue gas in the later stage cannot provide heat for the heat exchange medium, and it will only increase the adhesion of the flue gas particles to the heat exchange. The surface of the mechanism reduces the heat transfer performance of the heat exchange mechanism, so it is necessary to switch the flue gas out of the heat exchange pipeline when the flue gas temperature is low; in addition, for the sak...
