Embodiment Construction
[0015] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.
[0016] The core of this application is to provide a non-stop on-line cleaning device applied to rotary heat exchangers, which can solve the problem in the prior art of how to realize automatic cleaning of rotary heat exchangers without stopping the unit.
[0017] In actual production, each boiler is generally equipped with two rotary heat exchangers. For example, a 600MW thermal power unit is equipped with two three-compartment rotary heat exchangers. The rotor diameter of the rotary heat exchanger is 14236mm, and the heat storage element The total height of the machine is 2300mm, and the speed is 1.05r / min. The air flow arrangement of the rotary heat exchanger: the flue gas is downward, and ...

The invention discloses a non-stop online cleaning device applied to a rotary heat exchanger. The non-stop online cleaning device comprises a supporting frame and a control cabinet. A motor and a gearbox are mounted on one side of the supporting frame. A driving shaft and a driven shaft are rotatably connected to the opposite sidewalls of the interior of the supporting frame. One end of the driving shaft is fixedly connected with an output shaft of the gearbox. A driving wheel and a driven wheel are mounted on the driving shaft and the driven shaft correspondingly. The driving wheel and the driven wheel are connected through a chain. A steel pipe internally provided with a water pipe penetrates through the supporting frame in the length direction. The steel pipe makes contact with the driving shaft and the driven shaft. The water inlet end of the water pipe is connected with a high-pressure pump. A spray head is perpendicularly mounted at the water outlet end of the water pipe. The spray head is fixed to the steel pipe. Supporting rods are fixed to the bottom of the supporting frame. The non-stop online cleaning device is mounted on the spot and can control the motor and the gearbox to operate through the control cabinet to ultimately drive the steel pipe to move and then conduct cleaning on the whole surface of the rotary heat exchanger through the spray head. The non-stop online cleaning device can improves the cleaning efficiency and conduct online automatic cleaning when a unit is not stopped and is high in production efficiency.
Description
technical field [0001] The present application relates to the application field of rotary heat exchangers, in particular to a non-stop online cleaning device applied to rotary heat exchangers. Background technique [0002] A thermal power plant is a factory that uses combustibles (such as coal) as fuel to produce electric energy. During the production process, there will inevitably be fouling and ash problems in the rotary heat exchanger and the rotary gas-gas heat exchanger (GGH), resulting in The pressure difference of the heat storage element of the rotary heat exchanger increases, the induced draft fan surges, etc., especially after the environmental protection transformation is carried out and the out-of-stock device is installed, due to the improper control of the out-of-stock process, the fouling of the rotary heat exchanger is more frequent and serious. In order to ensure the safe and efficient operation of the unit, it is necessary to clean and dredge the heat stora...
