FILTER FOR DRINKING WATER

The utility model relates to filtering processes, namely, the device filters designed to purify drinking water from mechanical impurities and other harmful to human health micro-impurities and bacteria.

A known filter for the purification of drinking water, containing, as claimed, a vertical cylindrical body with a bottom, an upper removable housing cover, inlet and outlet nozzles and filter elements located inside the housing (RU 2040303 C1, 07.27.95, IPC - 01 D 24 / 08, 29/58, C 02 F 1 / 28-).

However, the known design does not provide high efficiency of water purification, since the fractionating process of drinking water purification with high absorption capacity in relation to numerous components of harmful impurities is not provided in this design.

The objective of the proposed utility model is to develop a filter design that has a high selective absorption capacity in the process of water filtration in relation to such components of impurities as heavy metal ions (iron, zinc, copper, strontium, cadmium), sulfates and nitrates, residual chlorine and phenol, organic impurities, radionuclides and bacteria.

comprising a vertical cylindrical housing with a bottom, an upper removable housing cover, inlet and outlet nozzles and filter materials located inside the housing and a filter element, according to a utility model, the filter element is made in the form of a cylindrical pipe, between the outer and inner walls of which there is activated carbon filter material fiber. The outer and inner walls of the filter element are perforated. The filter element is placed cooxially inside the housing with the formation of an annular space enclosed between the outer wall of the filter element and the wall of the housing and filled with filter material from mineral granular chips. The inlet pipe is installed at the bottom of the housing. The outlet opening of the inlet pipe communicates with the annular space, and the inlet with the water source. The outlet pipe is installed in the top cover coaxially with the central axis of the housing. The inlet of the outlet pipe communicates with the Central hole of the filter element, and the outlet with the consumer.

In addition, filter means made of nylon fabric can be installed in the outlet of the inlet pipe.

It is recommended that the top cover is in the form of a cylindrical flange.

It is advisable that the filter be equipped with a screen with filter cloth, and in the cylindrical flange an annular cavity is made, which is in communication with the annular space and is closed by the said screen, while an ion exchanger of bactericidal action is placed in the annular cavity.

The figure shows a General view of the filter for the purification of drinking water in a section along the plane of symmetry.

The filter for drinking water purification contains a vertical cylindrical housing (1) with a bottom (2), an upper removable cover (3) of the housing, inlet and outlet pipes (4,5) and filter materials located inside the housing and a filter element (6). The filter element is made in the form of a cylindrical pipe, between the outer and inner walls of which there is a filter material (7) made of activated carbon fiber (carbon fabric). The outer and inner walls of the filter element are perforated, the filter element (6) is installed coaxially relative to the housing (1) with the formation of an annular space (8), enclosed between the outer wall of the filter element and the wall of the housing and filled with filtering material made of mineral (marble) granular crumbs. The inlet pipe (4) is installed at the bottom of the housing. The outlet opening of the inlet pipe (5) communicates with the annular space (8), and the inlet - with a water source. The outlet pipe is installed in the upper cover (3) coaxially with the central axis of the housing. The inlet of the outlet pipe communicates with the Central hole (9) of the filter element (6), and the outlet with the consumer. In the outlet opening of the inlet pipe, filtering means (10) of nylon fabric can be installed. It is recommended that the top cover is in the form of a cylindrical flange. It is advisable that the filter was provided with a screen (11) with a filter cloth, and in the cylindrical flange an annular cavity (12) was made, which communicates with the annular space (8) and is closed by the screen. In this case, a bactericidal ion exchanger is placed in the annular cavity.

The filter for drinking water purification works as follows.

Water from the source through the inlet pipe (4) and filtering agent (10), in which it is purified from insoluble impurities, enters the annular space (8) filled with filtering material from mineral granular crumbs, where the water is purified from the increased content of heavy metals. For example, oxygen released by a mineral crust during the passage of water oxidizes ferrous iron to ferric iron, the compounds of which, as a result of hydrolysis, form hardly soluble hydroxide released from water and delayed by loading the filter. Thanks to the annular cavity (12) filled with a bactericidal ion exchanger, the water in the annular space (8) is cleaned of bacteria. Then the purified water enters the filter element (6) through perforation in its walls and passes through the filter material (7) from activated carbon fiber, in which further purification of water from sulfates and nitrites, residual chlorine, phenol, from organic impurities and radionuclides takes place. Next, the purified water through the Central hole (9) of the filter element (6) and the outlet pipe (5) is supplied to the consumer.

materials of various types of annular space filled with filter material from mineral granular chips and a filter element made in the form of a cylindrical tube, between the outer and inner walls of which filter material made of activated carbon fiber is located, allows for high selective absorption capacity (high efficiency of water purification ) in relation to various components contained in the source water - such as heavy metal ions, sulfates and nitrite atoms, residual chlorine and phenol, organic impurities, radionuclides and bacteria.
