DEVICE FOR LIQUID FILTRATION Russian patent published in 2015 - IPC B01D29/66 

FIELD: chemistry.

SUBSTANCE: device for liquid filtration contains filter with filtering element and placed in lower part pipeline for sediment draining, connected with valve for sediment draining, pipeline of initial unpurified liquid with valve on input to filter, force-pump, placed on input to pipeline of initial liquid, pipeline of purified liquid with valve on filter output, additional pipeline with valve, one end of which is connected with initial liquid pipeline before valve of initial liquid pipeline, and the other end - with pipeline of purified liquid between filter and valve of said pipeline, and on pump output and filter output installed are manometers with ratio D₂/D₁≤l, where D₂ is diameter of pipeline for sediment draining, D₁ is diameter of pipeline of purified liquid. Additionally installed is branch pipe, input of which is connected with additional pipeline between valve of additional pipeline and output pipeline, and output is connected with output pipeline between valve of purified liquid pipeline and filter output with ratio D₃/D₄ = 1.5-3.5, where D₃ is diameter of additional pipeline, and D₄ is branch pipe diameter.

EFFECT: continuous realisation of process of liquid passing without stopping of liquid passing process for operation of filtering element purification.
