Abstract

A waste incineration fly ash ultrasonic washing device is disclosed, a fly ash ultrasonic washing unit comprises a fly ash ultrasonic washing container, and the fly ash ultrasonic washing container is provided with a fly ash pneumatic conveying and entering area, a fly ash washing and dissolving area and a fly ash settling area; and the fly ash washing and dissolving area is located on the lower portion of the fly ash pneumatic conveying and entering area and provided with an ultrasonic assembly. The fly ash settling area is positioned at the lower portion of the fly ash washing and dissolving area; a fly ash conveying unit is connected with the fly ash pneumatic conveying and entering area, and the fly ash conveying unit conveys fly ash to the fly ash pneumatic conveying and entering area; and a spraying unit is connected with the fly ash pneumatic conveying and entering area and is used for spraying the fly ash of the fly ash conveying unit. According to the waste incineration fly ash ultrasonic washing device, the dissolution rate of chlorine salt in the fly ash and the dissolution and flocculation of heavy metal ions can be improved to the greatest extent, the cost is low, and the benefit is high; the liquid-solid ratio is relatively low, water resources are saved, the dehydration performance of the washed fly ash is improved, and the water content of the dehydrated washed fly ash is reduced; and continuous washing and discharging can be realized.

Description

technical field [0001] The invention relates to an ultrasonic water washing device for waste incineration fly ash, which belongs to the technical field of hazardous solid waste treatment. Background technique [0002] With the acceleration of my country's new-type urbanization process, the generation and accumulation of urban domestic waste are increasing year by year. At present, the main methods of waste disposal at home and abroad are sanitary landfill, composting and incineration. Among them, domestic waste incineration technology has been widely used because of its advantages of harmlessness, reduction and resource utilization. However, a large amount of fly ash will be produced during the incineration process of waste. The fly ash of waste incineration is rich in highly toxic heavy metals and dioxins, which will cause serious harm to the environment and human beings. Therefore, all countries in the world have listed fly ash as hazardous waste. thing. [0003] In the ...
