A type of dust remover with mechanical dust remover Tube box type waste heat boiler , including boiler drum, furnace water wall, superheater, evaporator, economizer, water heater, tube box shell, body pipeline, mechanical ash removal device of superheater, evaporator, economizer, tube bundle of heating surface of water heater and sealing device outside the tube box shell;

The mechanical ash cleaning device comprises an internal ash cleaning device, an external transmission device and an electrical control device; The internal ash cleaning device includes an internal elastic frame, a brush for cleaning the silica fume outside the pipe wall and an external fixed frame. The brush is installed on the internal elastic frame, the internal elastic frame is connected with the external fixed frame, and the external fixed frame is equipped with rollers that roll on the guide rail of the external transmission device to complete the movement of the internal ash cleaning device; The external transmission device includes guide rail, steel wire rope, drum, drive motor, reduction spring, travel switch and reduction transmission mechanism. The guide rail is located in the casing, the steel wire rope is connected with the internal elastic frame of the internal ash cleaning device, and both ends of the steel wire rope are respectively fixed on the left and right drums on the left and right sides of the casing, The left and right drums are respectively connected with the left and right drive motors through the left and right reduction drive mechanisms; A travel switch is respectively set at both ends of the guide rail. The travel switch is connected to the electrical control device to control the forward and reverse rotation of the drive motor to complete the reverse movement of the internal ash removal device when it moves on the guide rail to both ends.

Tube box type waste heat boiler Each layer of tube box type heating module is delivered in two pieces. When lifting, it needs to be lifted in two times. After two half of the tube boxes are in place, they are spliced and assembled. However, there is no formal support device below the heating module on each floor before it is in place, so a temporary support lifting device should be made before lifting. Since there is no rigid support in the middle of the module, the overall flexibility is large, and the existing temporary support lifting device is easy to cause deformation of the heating module when supporting the heating module, affecting lifting.
