Outline
Currently, the method of preventing siltation of water intakes in mountain rivers is a passive measure, i.e., allowing the unit to be shut down and then manually dismantling and cleaning the filter elements. This method is inefficient and time-consuming with poor safety. A new type of rotary filter is proposed to address the problems of easy clogging and high maintenance cost of traditional basket filters. FLUENT was used to establish a three-dimensional water flow mathematical model to simulate the changes in the flow and pressure fields inside the filter under the conditions of clear and muddy water, and the head loss of the traditional basket filter and rotary filter was analyzed. Compared with the traditional basket filter, it shows that the rotary filter can effectively slow down the silt fall, improve the water capacity of the filter, and effectively extend the working time of the filter. The study can provide design reference and theoretical basis for the improvement and optimization of water intake filters in mountainous rivers.
