Vacuum filter applied to fly ash washing system
Technical Field
The invention relates to the technical field of fly ash treatment, in particular to a vacuum filter applied to a fly ash washing system.
Background
The project of utilizing the cement kiln to treat the waste incineration fly ash in a coordinated manner is to recycle the fly ash collected after the municipal solid waste is incinerated, the main process flow of the project is to wash the collected fly ash with water, the residual fly ash after the washing is dried is fired into cement, and the waste water generated by the washing is collected, treated and reused for the fly ash washing again after meeting the recycling requirement. The reason why the fly ash must be washed with water is that the fly ash contains a large amount of chloride ions, which affect the quality of cement if not removed, i.e., only the chloride ions are removed and can be disposed of in the cement kiln.
The problems of the prior fly ash washing device are mainly as follows: inconvenient use and control, and the direct filtration easily causes the load of filtering component to be higher, influences vacuum filtration effect and efficiency. Therefore, in view of the above situation, there is an urgent need to develop a vacuum filter applied to a fly ash washing system to overcome the shortcomings in the current practical application.
