(54) FILTRATION INSTALLATION FOR CLEANING LIQUID FROM WEIGHED IMPURITIES

one

The invention relates to a device for purifying water from mechanical suspension, and can be used in the mining, chemical and other fields.

A known filtration system for cleaning liquids from suspended impurities, containing at least two sections of pressure filters, reservoirs for introducing raw water, draining wash water and draining filtrate 1.

The disadvantage of this installation is the low efficiency of water purification, due to the fact that after regeneration of one of the sections, the first portion of the contaminated filtrate is sent to the filtrate drain collector.

The purpose of the invention is to increase the cleaning efficiency of the filtration plant.

The goal is achieved by the fact that a filtration plant for cleaning liquids from suspended impurities, containing at least two sections of pressure filters, collectors for introducing raw water, draining wash water and draining filtrate, has

a distributor and switches connecting the section to the source water inlet and filtrate collectors, respectively, each of which is provided with a nozzle installed rotatably with respect to the switching axis and subsequently connecting sections for regeneration with the wash water outlet collector.

FIG. 1 is a schematic representation of a filtration plant, a general view; in fig. 2 switching option, cross section.

The filtration unit contains a series of pressure filter sections 1, a dispenser and a receiving switch 2 and 3, a source water inlet manifold 4, a filtrate drain collector 5, a wash water drain collector 6. The pipes 7 connect the switches with sections 1 and have a shut-off valve. Each switch 2 or 3 contains a housing 9 with openings for connection to the pipes 7 and the collectors 4 of the input water supply or collectors 5 of filtrate drainage, as well as the collector 6

industrial waste water. The socket 10 is switched with the possibility of being rotated relative to the switching axis.

Filtration unit works as follows. The source water is supplied to the section- days 1 through the collector 4, the switch 2 and the pipelines 7. Pass through the sections, the purified water enters the filtrate collector 5 through the receiving switch 3.

To regenerate the filtering material 10 of one of the sections, the valve 8, installed between switch 3 and collector 5 of the filtrate outlet, is covered, and switch 2 is set in a position that closes the access of the source water to the regenerated section and connects it with a pipe 4 collector 6 removal of wash water. After washing the section, the switch 2 is set to a position that ensures the supply of the source water to the washed out

Section 3 and the connection of the section with the collector 6. After removing the first portion of the contaminated filtrate, the lower section is transferred to the filtering mode, and the switch 3 connects this section to the collector of the 5 filtrate outlet. After that, proceed to the next c5 section.

The described filteringLsha installation has a simple design with minimal JQ

The number of pipelines allows to increase the filtration efficiency and simplify the scheme of automatic control of the filter cycle.
