The invention provides a reverse rotation dedusting device, comprising a main unit. The main unit is a rectangle box. An ash hopper is arranged on the lower part of the main unit and comprises four inclined surfaces. The upper space of the main unit is divided into an air inlet chamber and a separation chamber through a baffle plate. The lower space of the main unit is provided with a plurality of vertical baffles basically along an inclined surface of the ash hoppers; a gas flow route is formed between all baffle plates and the inclined surfaces, in convenient for wide upstream side and a narrow downstream side. The baffle plate on the upstream side is long in the vertical direction; furthermore, the interval between all baffle plates has narrow upstream side and wide downstream side. The airflow in the gas flow route ascends along the baffle plate and is rectified on the upstream side through the baffle plate; the baffle plate is long in the vertical direction, so as to lead the airflow to be basically a lamellar flow and to flow into the separation chamber. The flowing speed of the airflow is restricted by flow resistance between the baffle plates, thus leading the flowing speed to be more uniform.

The invention discloses a heat exchanger with a corrugated pipe coil structure provided with an internal duct and an external duct, which comprises an inlet, an outlet, a corrugated pipe, a dome, an internal ring bushing, an external ring bushing, a fan and a bracket. When fluid media to be in heat exchange flow in the corrugated pipe in the heat exchanger from the inlet, form a turbulent flow ina pipe wall with a corrugated structure and carry out heat exchange with air in the internal duct and the external duct outside the corrugated pipe via the wall of the corrugated pipe, the fan discharges air in the internal duct and the external duct, and the fluid media are discharged from the outlet after the heat exchange performed in the corrugated pipe in a spiral way. The heat exchanger hasthe advantages of high heat exchanger effectiveness, simple structural technology, light weight, integration, and the like, and the fluid media in the pipe coil after the heat exchange have even temperature, thereby the heat exchanger can be used for heat exchange of air, liquid and air-liquid mixing substances. When the corrugated pipe adopts resistant materials, the heat exchanger can be used for heat exchange for corrosive liquid media.
