FILTRATION INSTALLATION Russian patent published in 2004 - IPC

FIELD: filtration installations for chemical and food and other industries.

SUBSTANCE: the invention presents a filtration installation for filtration of liquids and may be used for purification of natural waters and sewage, concentrating of solutions in chemical, food and other industries. The filtration installation contains a filter, a hydraulic accumulator, pipelines of an initial, purified and non-purified liquid with gates, a pump, a by-pass flow control gate, an electrogate installed on the pipeline non-purified liquid. The installation is equipped with gauges of pressure mounted on the pipelines of purified and non-purified liquid with a capability to transfer a signal to the electrogate. On the pipeline of the initial liquid there is a gate keeping up consumption of the initial liquid during its washing operation at the same level as during filtration. The technical result is a raise of productivity of installation due to an increase outlet of the purified liquid, increased service life of the filter of the installation at the expense of increased difference of pressures in the filter at washing action.

EFFECT: the invention ensures a raise of productivity of installation, increased outlet of the purified liquid, increased service life of the filter of the installation.
