Water scrubber for waste incineration fly ash and water washing method

Abstract

The invention discloses a water scrubber for waste incineration fly ash and a water washing method, the water scrubber comprises a stirring container, a stirring device and a filtering device, the inner wall of the stirring container is of a cylindrical structure, and the bottom of the stirring container is provided with an inverted-circular-truncated-cone-shaped groove. Stirring blades of the stirring device are arranged in the stirring container. The filtering device is fixedly mounted in the inverted-circular-truncated-cone-shaped groove in the bottom of the stirring container and comprises a filtering element, a sealing element, a backwashing element and a suction filtration chamber. The filtering element comprises a first punched mesh plate, a superfine glass fiber filter membrane and a second punched mesh plate which are sequentially stacked, the sealing element comprises a cover body and a base, a through hole is formed in the middle of the cover body, and the cover body and the base are matched with each other to form a filter chamber. The backwashing element, the suction filtration chamber and the filtering element are sequentially arranged in the filter chamber from bottom to top, the filtering element is arranged opposite to the middle through hole of the cover body, and the diameter of the filtering element is larger than that of the middle through hole of the cover body.

Description

technical field [0001] The invention relates to the technical field of waste fly ash treatment, in particular to a water washer and a water washing method for waste incineration fly ash. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Incineration is a high-temperature heat treatment technology. Because incineration treatment can achieve the purposes of heat energy recovery, volume reduction and weight reduction of municipal waste, it has 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 municipal solid waste incineration fly ash (MSWI-FA for...
