Waste heat-utilized generating device of cement kiln

水泥窑余热利用发电装置

Abstract

The utility model relates to a waste heat generating device of a cement kiln, and particularly discloses a waste heat-utilized generating device of a cement kiln, which includes a cement rotary kiln (8), as well as a waste heat recovering cylinder (1), a turbine (2) and a generator (3), wherein the waste heat recovering cylinder (1) is sleeved outside the cement rotary kiln (8), and a water-filled interlayer (1-1) is arranged inside the side wall of the waste heat recovering cylinder (1); the water-filled interlayer (1-1) is connected with the turbine (2) through a water pipe, and an electric heater (1-2) is arranged on the water pipe; the turbine (2) is connected with the generator (3); and a water outlet pipe of the turbine (2) is connected with a condenser (4), the condenser (4) is connected with a water supplementing tank (7), and the water supplementing tank (7) is connected with a water return opening of the waste heat recovering cylinder (1) through the water pipe. The waste heat-utilized generating device of the cement kiln solves the problem that a large amount of waste heat produced during the production of the cement rotary kiln can't be effectively utilized.
