FLUID CLEANING SYSTEM Russian patent published in 2017 - IPC C02F1/44 B01D61/02 

FIELD: technological processes.

SUBSTANCE: invention relates to the cleaning systems and/or desalting the liquid, preferably water. Fluid purification system contains a supply line of the original fluid with mounted supply valve source fluid, connected to the filtration unit, which comprises liquid cleaning means with an inlet for source liquid and outputs for the purified and drain liquid; the fluid mixing device, pressure means support unit, mixing line for the source liquid concentrate, that is formed during the fluid treatment, in a liquid cleaning means, recycling line, the purified fluid line, the fluid drain line and the control unit associated with means of pressure support, pressure change control means, and source liquid supply valve . The filtration unit is adapted to stabilize the pressure in the fluid purification means at periodic fluid flow drainage to drain the fluid velocity, exceeding the performance of pressure support means, disposed on the source liquid line upstream of the device mixing fluid, made in the form of a pressure vessel, which is connected with a line mixing original liquid and concentrate, formed during the filtering process, and simultaneously adjusting of the concentrated fluid volume in the mixing apparatus due to the relationship of the control unit to support the pressure means in the fluid mixing apparatus, performed in a pressure vessel and with means of maintaining the circulation of fluid flow located in the line feeding the starting fluid mixture and concentrate The recirculation line through the connection node is connected to the source liquid supply line, after pressure suuport means and the mixing line of the source liquid and the concentrate, which is connected to the mixing device of the source liquid and the concentrate.

EFFECT: invention increases the life of the fluid treatment system, increases efficiency, and reduces the initial fluid energy costs.
