FILTERING SYSTEM

Abstract

Disclosed is a filtering system used in any pool filtrations, filtration of taps or building entrance hot and cold use water, filtration of city water before osmosis filtering devices, filtration of heating and cooling mechanical plant systems, and filtration of cooling water in hydro-electric power plants. The system provides for forming a vortex inside a filter by directing and increasing speed of filtered liquid and thus providing decreasing pressure on the filter surface and collection of filtered particulates in a particulate accumulation chamber. The system also provides for automatic cleaning of the filter by reverse flushing, without the need for dismantling, by differential pressure sensors based on rate of contamination.

DETAILED DESCRIPTION OF THE INVENTION

[0037] In this detailed description, the preferred alternatives of filtering system being subject of the invention have been described in a manner not forming any restrictive effect and only for purpose of better understanding of the matter.

[0038] FIG. 1 shows illustrative view of filtering system of the invention. Accordingly, in the most basic form, the filtering system comprises filter chamber (10) located in vertical position on a foot (100), a filter (20) located in filter chamber (10) center and providing filtration of particulates, particulate accumulation chamber (30) located under the filter (20) and providing accumulation of filtered particulates, an inlet line (40) vertically located in filter (20) center in order to provide entrance of water to be filtered into the system, vortex cap (50) located on end of water outlet of inlet line (40), an outlet line (60) associated to filter chamber (10) and providing discharge of filtered water from the system, an engine valve (70) located on water inlet line (40) and outlet line (60) at flushing water outlet (31) at lower end of particulate accumulation chamber (30) at flushing water inlet (11) on the filter chamber (10) in order to provide control of inlet-outlet of water to be filtered in the system and flushing water, a differential pressure sensor (80) connected onto inlet line (40) and outlet line (60) and measuring pressure in the system and turning on/off the engine valves (70), an automatic air discharge device (90) connected to filter chamber (10) and discharging the air inside the filter chamber (10).

[0039] Filter chamber (10) forming main embodiment of the filtering system is located on a foot (100) in vertical axis. Filter chamber (10) has flushing water inlet (11).

[0040] Filer chamber (10) centre has a filter (20) providing filtration of particulates.

[0041] A particulate accumulation chamber (30) providing accumulation of filtered particulates and having a flush water outlet (31) at the lower and is located under the filter (20). The flush water outlet (31) provides exit from particulate accumulation chamber (30), of water entering through flush water inlet (11) on the filter chamber (10) in order to provide reverse flush of particulate accumulation chamber (30).

[0042] Inlet line (40) providing inlet of water to be filtered in the use area of filtering system, is located vertical position to filter (20) centre. Vortex cap (50) is provided on the end provided inside filter (20) of inlet line (40) providing entrance of water to be filtered into the system. Vortex cap (50) provides flow of water from inlet line (40) downward inside the filter (20).

[0043] Outlet line (60) is connected to filter chamber (10) in order to provide exit of filtered water from system through filter (20).

[0044] Engine valve (70) is connected to flushing water inlet (11) on filter chamber (10) and flush water outlet (31) on lower end of particulate accumulation chamber (30) to provide control of inlet-outlet of flush water in the system and also onto water inlet line (40) and outlet line (60) to provide control of inlet and outlet of water to be filtered in the system.

[0045] Differential pressure sensor (80) is connected to measure pressure of system onto inlet line (40) and outlet line (60) to provide turning on/off of engine valves (70) in order to provide flushing of filter (20) and particulate accumulation chamber (30) by reverse flushing and provide display of pollution rate of the filter (20).

[0046] Filter chamber (10) is connected to automatic air discharge device (90) providing discharge of air therein.

[0047] Working principle of filtering system of the invention is as follow;

[0048] Engine valve (70) connected to water inlet line (40) and outlet line (60) is in open position during water flowing in the filtering system. Water entering through inlet line (40) hits the vortex cap (50) on end of water inlet line (40) and flows downward inside the filter (20). During downward flowing of the water inside filter (20), vortex occurs inside filter (20) depending on flow rate of water and filling of water into filter chamber (10) from down to upwards is provided by means of providing flow of water through filter (20) by reducing pressure on filter (20) surface.

[0049] The particulates remaining inside the filter (20) during filling of water into filter chamber (10) after passing through filter (20) moves towards particulate accumulation chamber (30) and accumulate in the particulate accumulation chamber (30). Filtered water exits through exit line (60) connected to filter chamber (10).

[0050] After use of filtering system for a fixed time period, pressure in the system is measured by differential pressure sensors (80) on inlet line (40) and outlet line (60) as per pollution of filter (20). When pollution level of the filter (20) reaches a fixed level, differential pressure sensors (80) shut down the engine valves (70) connected to inlet line (40) and outlet line (60). Then they open engine valves (70) located on flush water inlet (11) and flush water outlet (31). Reverse flushing is performed by water entering through flush water inlet (11) and exiting from flush water outlet (31) on lower end of particulate accumulation chamber (30). Flush water is discharged from flush water outlet (31) together with the particulates in the particulate accumulation chamber (30) and thus filtering system is cleaned.

[0051] Air forming in the system during cleaning operation is discharged through automatic air discharge device (90).
