Description

The utility model relates to water supply systems, in particular to devices for removing or supplying air and purifying incoming air into clean water tanks (CW) when they are filled or emptied.

A water supply system is known (RU 2042017 C1, class E03B 7/04, 08/20/1995), where a chamber with air purification filters is installed in the upper part of the tower. One of the disadvantages of the design is the installation of a column inside (RCV) under the base of a capital structure.

There is a well-known standard project of Giprokommunvodokanal TP 0901-9-16.1.87 “Absorber filters for clean water reservoirs,” which consist of a chamber located in the same embankment with technological equipment that is common with the reservoir.

The disadvantages of the design of the structure for placing absorber filters for purifying the air entering the RHF are the need to allocate space in the sanitary zone of the water supply facility for their placement, the high estimated cost of the structure, as well as a longer project implementation period.

The closest analogue is an air exchange unit, which is an insulated module, the body of which is made of polymer material, mounted directly on the RHF coating slab; containing an exhaust air duct for releasing air from the RHF through a check valve; a replaceable synthetic filter element for cleaning air coming from the atmosphere into the RHF through the supply air duct through the check valve of the supply air duct branch pipe; an automatic emergency system that provides, using an electric drive, the opening of the emergency air duct shutter for the emergency intake or release of air from the radio frequency unit when the specified pressure limits are reached. The air inlet and outlet check valves are located below the RHF cover plate, which prevents the formation of ice and disruption of their functioning. The air ducts are separated from each other and operate independently of each other to prevent the formation of condensation and icing of the surface of the pipes.

The task facing the authors is to improve the design of the air exchange unit, making it possible to more effectively purify the air passing inside the body of the insulated module of the air exchange unit.

This task is achieved thanks to the essence of the claimed utility model, which allows for additional purification of the air from microbes, bacteria, viruses, fungi due to the installation of an ultraviolet lamp and an ozonizer inside the body of the insulated module, along the path of air movement passing through the filter elements to the check valve of the supply air duct.

Application of an ozonizer: ozone allows you to purify the air not only inside the air exchange unit before supplying it to the RHF, but also to disinfect air, water and the surface of walls directly in the RHF.

Application of a UV lamp: continuous operation of UV rays makes it possible to effectively disinfect surfaces inside the filtration chamber and filter elements, thereby preventing the appearance of mold and preventing the penetration of its spores into the RHF

Figure 1 shows an air exchange installation for RHF with an installed ultraviolet lamp and ozonizer;

Fig. 2 shows the operation of the installation during the removal of air from the RHF;

Fig. 3 shows the operation of the installation at the moment of air supply to the tank;

Figure 4 shows the operation of the installation in emergency mode.

The air exchange unit contains 1 - insulated module housing, 2 - exhaust air duct, 3 - check valve of the exhaust air duct, 4 - supply air duct, 5 - filter elements, 6 - check valve of the supply air duct branch pipe, 7 - emergency air duct electric drive, 8 - emergency air duct damper , 9 - emergency air duct, 10 - RHF, 11 - ultraviolet lamp, 12 - ozonizer.

The air exchange unit is an insulated module 1, the body of which is made of a polymer material that is not subject to corrosion, with the ability to be mounted directly on the RCHV 10 coating slab; containing an exhaust air duct 2 for releasing air from the RHF through a check valve 3; replaceable filter elements 5 for cleaning the air coming from the atmosphere into the RHF 10 through the supply air duct 4, through the check valve 6 of the supply air duct branch pipe; an automatic emergency system that, using an electric drive 7, ensures the opening of the emergency air duct valve 8 for the emergency intake or release of air from the air control unit 10 when the specified pressure limits are reached. Check valves 3;6 for air inlet and outlet are located below the RCHV 10 coating plate, which prevents the formation of ice and disruption of their functioning. Air ducts 2;4 are separated from each other and operate independently of each other to prevent the formation of condensation and icing of the surface of the pipes. An ultraviolet lamp 11 and an ozonizer 12, installed along the path of air passing through the filter elements 5 to the check valve 6 of the supply air duct, provide additional purification of the air from microbes, bacteria, and viruses.

The device operates in 3 modes:

1. At the moment water enters the RHF, air is removed through the outlet air duct 2 (shown by arrows) through the check valve 3 of the outlet air duct (Fig. 2)

2. In the process of emptying the RHF, air enters through the supply air duct 4, which passes through the filter elements 5, with additional cleaning and disinfection thanks to the ultraviolet lamp 11 and the ozonizer 12, after which it passes through the check valve of the supply air duct branch pipe 6 (Fig. 3)

3. Emergency mode. An automatic emergency system is provided as protection against collapse of the RHF structure when specified pressure limits (excess or vacuum) are reached. This system, using an electric drive 7, ensures automatic opening of the valve 8 for emergency air intake or exhaust through an independent emergency air duct 9 (Fig. 4)

The effect of using the installation is:

reducing the area where water supply facilities will be located and operating costs (lighting, heating, land payments);

reducing the estimated cost of building an air exchange unit;

reducing construction time by reducing the total volume of excavation, construction and installation work, filter-absorber equipment;

ease of replacing and cleaning filter elements;

additional purification of the air passing inside the installation housing from bacteria, microbes and viruses with their complete destruction, due to ultraviolet disinfection and ozonation.

The task has been completed.
