Description

Technical Field

[0001] This invention relates to the field of fly ash treatment technology, specifically to a fly ash water washing treatment device. Background Technology

[0002] Fly ash, a major byproduct of waste incineration, has a composition similar to SiO2-Al2O3-CaO-Fe2O3 in cement raw materials. It can be used as a substitute raw material for cement production and thus utilized as a resource. Therefore, to achieve harmless and resource-efficient treatment of fly ash, co-processing technology in cement kilns is often employed. Fly ash produced during waste incineration is not only rich in heavy metals, dioxins, and other toxic substances, but also contains high levels of soluble salts. High concentrations of chlorine can seriously endanger the safety of cement kiln production. Therefore, before co-processing fly ash in cement kilns, it must undergo water washing pretreatment. Common water washing equipment includes washing tanks.

[0003] Regarding the incineration fly ash washing treatment device disclosed in existing patent number CN202122570923.9, it can remove fly ash adhering to the inner wall and bottom of the tank by setting a first scraper and a second scraper, which can effectively prevent solid phase deposition caused by gravity settling of fly ash at the bottom of the tank, and has good practicality; the detachable connection between the tank body and the tank cover facilitates installation, disassembly and subsequent cleaning of the tank body, making it convenient to use; and the fact that both the first scraper and the second scraper can be detachably connected to the rotating shaft facilitates installation, disassembly and subsequent replacement of the first scraper and the second scraper, making it convenient to use.

[0004] However, the aforementioned fly ash washing treatment device has low mixing efficiency with the mixing agents and water during fly ash mixing and stirring, and lacks a filtration mechanism, which results in the fly ash needing to be stirred multiple times, affecting the working efficiency of the device; therefore, it does not meet the existing requirements, so we propose a fly ash washing treatment device.
