Abstract

The invention discloses a water washer and a water washing method for waste incineration fly ash, comprising a stirring container, a stirring device and a filtering device, wherein, the inner wall of the stirring container is a cylindrical structure, and an inverted table-shaped groove is provided at the bottom; The stirring blade of the stirring device is arranged inside the stirring container; the filter device is fixedly installed in the rounded platform-shaped groove at the bottom of the stirring container, which includes a filter element, a sealing element, a backwash element and a suction filter chamber; the filter element includes The first perforated screen, the ultrafine glass fiber filter membrane and the second perforated screen are stacked in sequence. The sealing element includes a cover and a base. A through hole is opened in the middle of the cover. The cover and the base cooperate with each other to form a filter cavity. chamber; inside the filter chamber, the backwash element, the suction filter chamber and the filter element are arranged in sequence from the bottom to the top, and the filter element is arranged opposite to the middle through hole of the cover body, and the diameter of the filter element is larger than the middle through hole of the cover body diameter of.

Description

Technical field [0001] The present invention relates to the field of garbage fly ash treatment technology, in particular to a water washer and water washing method for garbage incineration fly ash. Background [0002] Disclosure of the background technical portion of the information is only intended to increase the understanding of the general background of the present invention, and is not necessarily regarded as an acknowledgement or any indication in any form that the information constitutes prior art that has become commonly known to those of ordinary skill in the art. [0003] Incineration is a kind of high-temperature heat treatment technology, because incineration treatment can achieve the purpose of urban waste heat recovery, capacity reduction and weight reduction, so it has been developed rapidly. Under the trend of the promotion of waste incineration technology at home and abroad, not only the number of waste incineration plants has increased, but also the incineration...
