Description

TECHNICAL FIELD

[0001] The utility model relates to fly ash treatment technical field, and specifically, it relates to an intelligent intermittent fly ash stabilization device. BACKGROUND

[0002] With the acceleration of urbanization and the improvement of environmental awareness, waste incineration for power generation as an effective waste disposal method has been widely promoted and applied. Through high-temperature incineration, combustible substances in waste are converted into electrical energy, thereby realizing the resource utilization of waste. However, with the increasing amount of waste incineration year by year, the amount of fly ash produced is also increasing. Fly ash is a kind of fine particulate matter produced in the process of waste incineration, which contains harmful substances such as heavy metals and dioxins. If these substances are not properly treated, they may enter the ecological system through air, water and soil, etc. and cause serious impact on human health and the environment. Therefore, it is particularly important to stabilize the fly ash.

[0003] In the process of treating fly ash and chelating agent, the method of "first adding all fly ash, then adding chelating agent" is mostly used, and then mixing and stirring are carried out. However, when fly ash is first added and then chelating agent is added, due to the existence of gaps and agglomeration between fly ash particles, chelating agent may not penetrate into each fly ash particle quickly and uniformly, which may result in that part of the heavy metal ions in fly ash cannot be effectively chelated, thereby reducing the treatment effect. Due to uneven mixing, part of the chelating agent may not fully contact and react with the heavy metal ions in fly ash, resulting in waste of chelating agent, which not only reduces the use efficiency of chelating agent, but also may cause certain burden to the environment.

[0004] Therefore, in view of the above problems, the applicant has designed an intelligent intermittent fly ash stabilization device to solve the problems. CONTENT OF THE UTILITY MODEL
