Abstract
Disclosed are an anti-blocking system and an anti-blocking method based on ring-wise round-robin heating for a rotary heat exchanger. A cold end surface of a heat exchanger rotor is divided into N concentric rings by a circumferential partition plate, and N is greater than or equal to 2. N profiled cold medium pipes are arranged at a cold end of at least one cold medium compartment. Each of the profiled cold medium pipes is provided with a fan-shaped opening at a first end thereof and a rectangular opening at a second end thereof. The fan-shaped opening is arranged to correspond to a respective one of the concentric rings. Radial edges on two sides of the fan-shaped opening are respectively connected to side edges of cold-end fan-shaped plates in the respective one of the concentric rings, and a plane at which the fan-shaped opening is located is flush with sealing surfaces of the cold-end fan-shaped plates. The rectangular opening is provided with an automatic adjusting valve configured to adjust a flow of a cold medium, and the flow of the cold medium in each of the profiled cold medium pipes is reduced in a round-robin manner, to increase a wall temperature of heat storage elements in the respective one of the concentric rings, so that condensed or crystallized substances adhering to the heat storage elements are gradually gasified, and are discharged out of the heat exchanger rotor along with a hot medium. Therefore, the problem of blockage and corrosion of the rotary heat exchanger is effectively solved.
