The invention provides a structure for suspending a heated surface of a waste heat boiler at the tail of a cement kiln used for a waste heat power generation system. The invention also relates to a vibration device and a vibration method for the structure used for suspending the heated surface. The heated surface (4) is a pipe-shaped structure and arranged as a snake-shaped structure reciprocatedzigzag upwards and downwards; the upper bent part of the heated surface (4) close to a boiler framework (7) is suspended on the boiler framework (7); the vibration device is arranged at the positionsbelow the middle position of the heated surface (4); the vibration method is characterized in that a manual method or a mechanical method is adopted to apply the impact force on a vibration hammer (8); by the vibration device (9), the dusts adhere to the heated surface (4) is disconnected with the heated surface (4) due to the vibration. The structure, the vibration device and the vibration method have the beneficial effects that: firstly, the heated area dust can be reduced, the service life of the equipment is prolonged; secondly, compared with the vertical boiler, the quantity of the vibration devices on the heated surface is reduced, the heat exchanging efficiency is greatly improved; and thirdly, the maintenance workload of the boiler is obviously reduced.
Description
technical field [0001] The present invention relates to the field of pure low-temperature waste heat power generation system used in cement clinker production line, more specifically, the present invention relates to a suspension structure of heating pipes of waste heat boiler at the tail end of cement kiln used in waste heat power generation system, and the present invention also relates to this kind A rapping device and a rapping method for a heated tube suspension structure. Background technique [0002] The cement industry is a big energy consumer and a big waste of energy. In the past two years, the state has continued macro-control, and energy conservation and consumption reduction have become a subject that must be completed in the cement industry. Pure low-temperature waste heat power generation technology in cement kilns can solve this problem very well. In the field of pure low-temperature waste heat power generation technology in cement kilns, the design of waste ...
