The center cylinder is coaxially arranged at the center position in the outer shell, the inner rotor is rotationally arranged on the outer wall of the center cylinder, the outer wall of the inner rotor is rotationally connected with the inner wall of the outer shell, the inner rotor is driven by the driving piece located at one side of the outer shell, the flue gas inlet and the air outlet are formed in the top end of the outer shell, and the flue gas outlet and the air inlet are formed in the bottom end of the outer shell. The corrugated plate group and the ring pipe group are arranged in the inner rotor, and a plurality of disturbance mechanisms are circumferentially arranged on the inner wall of the ring pipe group. The flue gas and the air are transversely washed to the annular heat pipe, the heat exchange coefficient of the flue gas and the air is strengthened, the deposition rate and deposition amount of ammonium bisulfate on the heated surface can be significantly slowed down, and the safety risk is reduced.

The utility model discloses a rotary air pre-heater ring-dividing temperature rising system based on air heater zone management. The rotary air pre-heater ring-dividing temperature rising system comprises a rotor, a circumferential movable partition plate, a special-shaped static partition plate, a cold air inlet pipe and an air heater system. The circumferential movable partition plates are mounted on the lower end face of the rotor and divide the lower end face of the rotor into N concentric rings; the cold air inlet pipe is located below the lower end face of the rotor and at least covers one air branch bin. The special-shaped static partition plates are installed in the cold air inlet pipe, the cold air inlet pipe is divided into at least N independent ring-dividing air inlet pipes, and the ring-dividing air inlet pipes are located below the corresponding concentric rings. The air heater system comprises N partition air heaters, a heat source conveying pipe and N air heater partition air inlet valves, and the partition air heaters are installed in the corresponding branch ring air inlet pipes. One end of the heat source conveying pipe is connected with a heat source, the other end of the heat source conveying pipe is branched into N heat source branch pipes, the heat source branch pipes lead to the corresponding partition air heaters, and the air heater partition air inlet valves are installed on the corresponding heat source branch pipes. The device can solve the problems of blockage and corrosion.

The invention discloses a supercritical thermal power generating unit flexible power generation cooperative waste treatment system. The system comprises a material conveying system, a supercritical water oxidation reaction system and a waste heat utilization system. According to the invention, supercritical water oxidation treatment of waste water is carried out by using residual steam generated by residual load of the boiler, harmless treatment of waste is carried out by using the residual steam while safe load operation of the boiler is ensured, energy in China is transformed to green and low carbon, and environmental protection is realized. And a feasible system scheme is provided for improving the safe operation of the deep peak regulation unit in China.

The utility model discloses a rotary heat exchanger air leakage and ash clogging processing mechanism which comprises a cold end center truss, a hot end center truss and a fan, and the outer wall of the hot end center truss and the outer wall of the cold end center truss are both connected with sector plate assemblies. The air entraining end of the draught fan is connected with an air entraining gathering pipe, the end, away from the draught fan, of the air entraining gathering pipe is connected with a tee joint, and the two ends, not connected with the air entraining gathering pipe, of the tee joint are connected with a dredge air gathering pipe and a hot smoke outlet pipe respectively. The outer wall of the dredging air gathering pipe is communicated with a plurality of groups of cold-end fan-shaped plate dredging air pipelines, axial sealing plate dredging air pipelines, axial sealing plate dredging air pipelines and hot-end fan-shaped plate dredging air pipelines; and the air supply end of the fan is connected with an air supply gathering pipe. The utility model solves the problems that the ash cleaning effect is not ideal and the ash clogging becomes the most difficult problem of the rotary air preheater because the accumulated ash is formed and hardened on the surface of the heat transfer element.
