The utility model relates to the technical field of sewage treatment, in particular to a novel environment-friendly sewage treatment device which comprises a treatment box, a processing mechanism, which is used for processing; according to the treatment mechanism, impurities in sewage are preliminarily filtered by using a filter cartridge, so that more impurities are prevented from falling on a second filter plate, a motor is started to drive a rotating rod to drive a cleaning plate to rotate, and the cleaning plate is beneficial to pushing the impurities retained in the filter cartridge to a discharge groove in the rotating process and falling into a collection box through a guide frame for collection; meanwhile, through interaction of the acting force of water flow falling on second filter plates and second springs, continuous vibration of the two second filter plates in the filtering process is facilitated, so that the impurities on the second filter plates can better flow towards lower positions of inclined planes of the second filter plates, and the filtering effect of the filter cylinders is guaranteed. The impurities are prevented from being gathered on the second filter plates, so that the filtering effect of the two second filter plates on the impurities in the sewage is improved.

This utility model discloses a high-efficiency waste heat recovery device for waste incineration, including an incinerator. The furnace wall of the incinerator has a cavity, and a spiral heat exchange tube is installed inside the cavity. An installation pipe is fixedly inserted into the top of the incinerator. The inner cavity of the installation pipe is equipped with a filter assembly for filtering fly ash in the high-temperature flue gas generated by the incinerator. A cap is threaded to the outer circumference of the top of the installation pipe. A connecting hose is inserted into one side of the top of the cap. The end of the connecting hose is sleeved on the input end of the spiral heat exchange tube. By setting up the filter assembly and installing a filter cylinder inside the installation pipe, the fly ash can be initially intercepted before the high-temperature flue gas enters the conveying pipe, preventing fly ash from directly adhering to the inner wall of the pipe. This prevents the inner diameter of the conveying pipe from shrinking and clogging from the source, and reduces the frequency of shutdown for ash cleaning.
