Description

The utility model relates to the field of water supply, in particular to drinking water supply systems of guaranteed quality, providing round-the-clock access for residents of an apartment building, while the system is connected to public water supply networks. The utility model is used for the collective provision of drinking water to residents of an apartment building.

Terms and definitions used in the description.

The dirt filter is a pre-filter that purifies water from large particles of contamination.

The main filter is the main filter: purification of water from chlorine residues, chlorination by-products, soluble organic substances of natural and technogenic origin, suspended abrasive particles and possible precipitation of iron hydroxide, while improving the organoleptic properties of water (taste, smell, color); It is a fiberglass container with filter media (gravel and activated carbon), equipped with a water flow switch that operates in an automatically programmed mode.

Fine filter - a cartridge filter in which a replaceable cartridge with a filter fineness of 3-5 microns is installed, this processing stage is designed for fine purification of water from residual suspensions.

Water can contain many contaminants of various kinds, including, for example, microparticles, harmful chemicals, and several types of microorganisms, such as bacteria, parasites, cysts, and viruses. Any harmful contaminants must be removed from the water before it is suitable for safe human consumption. The consequences associated with exposure to contaminated water can be very serious and even fatal can occur, especially in underdeveloped countries. However, at the same time, there are several factors in these countries, including population density, water scarcity and / or lack of electricity, which can contribute to water pollution. In order to make water suitable for human consumption, many types of different water purification systems have been developed based on one or more purification methods. Water treatment methods are well known, including distillation, boiling, chemical disinfection, reverse osmosis, water filtration, and ultraviolet (UV) irradiation.

The urban water supply system provides an initial stage of water treatment. However, the quality of city tap water leaves much to be desired (the presence of chlorine residues, rust, metal salts, etc.) and makes urban residents look for sources of clean drinking water.

The main most common way to solve the problem of obtaining clean water in a city is to buy bottled water, or bottled drinking water in special kiosks, or to install an individual filter in each apartment. Buying water at kiosks and shops is economically unprofitable, inconvenient. There is no round-the-clock access, not all residents can carry heavy loads. Installing a filter is also a costly way for an individual consumer, in order to ensure high-quality after-treatment, you will have to purchase an expensive device, and then monitor its maintenance.

Known technical solution according to patent RU 2348763 C2, IPC EV03 1/04 (2006.01), publ. 04/09/2007, according to which the water supply system includes storage and consumable containers, the number of which is equal to the number of users of water, means for filling the indicated containers with water, interconnected piping system made of hygienically clean material, drain valves connected to the indicated containers, and a local water dispensing console and a means for collecting and processing information about the volume of water consumed by each user, with each storage and supply tank equipped with an inlet valve the upper water level in the tank, and the piping system is a distribution pipeline with pipelines leading to the storage and expenditure tanks. The disadvantage of this water supply system is: its complexity (many nodes, the reliability and safety of the system depend on the operation of which); large dimensions of containers located directly at the consumer, taking up a lot of space; the complexity of the maintenance and rehabilitation of the system and pipelines, due to the number of tanks, directly proportional to the number of consumers; in the event of a prolonged absence of the consumer, the water in the tanks will become unsuitable, since there will be no withdrawal, in addition, the known system does not provide consumer access to drinking water in case of stopping the supply of imported drinking water.

The closest is the technical solution according to patent RU 97399 U1 ЕВВ 1/04 (2006.01), publ. September 10, 2010, “DRINKING WATER CONSUMER SUPPLY SYSTEM” intended for water supply of a residential building, containing a storage-supply tank, a piping system, drain valves for a consumer connected to the indicated tanks by a pipeline, characterized in that the system contains a common storage-expendable tank , the piping system is equipped with a booster pump, a common water meter and water meters at the consumer, a disinfecting device at the outlet of the storage tank. Storage-expendable capacity can be made with a conical bottom and with thermal insulation. Disadvantages: the presence of an accumulative-expendable capacity limits the known system in the amount of water supplied, in addition, there is no treatment device, while the water from the city water supply does not comply with drinking water standards and needs additional treatment.

The technical task of the claimed utility model is the creation of an economical system for providing collective round-the-clock access to drinking water of guaranteed quality from public water supply networks with transportation to the place of consumption - each entrance (apartment) of an apartment building, which reduces the cost of purified water for consumers. To do this, an economical design of the support system is proposed, including water purification devices coming through public water supply channels, to the level of high-quality drinking water, which has universal application, cleans any incoming water volume, that is, it can be used in an apartment building.

In the basement of the apartment building at the inlet of the city water supply, a filtering installation for the purification of drinking water with the subsequent wiring of plastic pipes into all house entrances to the ground floor is equipped. When constructing a new apartment building, wiring can be performed directly to each apartment. The quality of urban tap water during transportation through the public water supply network is deteriorating (the presence of chlorine residues, rust, metal salts, etc.), which forces urban residents to look for sources of clean drinking water.

The support system installed in the house has the following characteristics:

- productivity is from 400 to 1500 l / hour;

- the operating mode is periodic;

- source of water supply - city water supply;

- the quality of the treated water at the outlet is similar to the purchased water (for example, bottled or sold in bottling at kiosks).

Preliminary water purification is carried out through a mud filter. Then, in the main filter, during the filtration process, the water is purified from chlorine residues, by-products of chlorination, soluble organic substances of natural and technogenic origin, suspended abrasive particles and a possible precipitate of iron hydroxide, while the organoleptic properties of water (taste, smell, color) are improved. The main filter is fully automated and does not require the constant presence of staff. In order to prevent caking of activated carbon and removal of possible contaminants every 2-3 days, the filter is backwashed with source water. Flushing is carried out without the use of special pumps due to the pressure of the source water. The frequency and time to start flushing are set using the electronic control unit at a convenient (night) time of the day. After activation of the sorption capacity, it is necessary to replace the filter load. The required replacement frequency depends on the characteristics of the source water, is approximately 1 time in 1-1.5 and is specified during operation. After the main filter, water passes through a fine filter: a cartridge filter in which a replaceable cartridge with a filter fineness of 3-5 microns is installed. This processing stage is intended for fine purification of water from residual suspensions. The frequency of replacement is 3-4 times per quarter. After the fine filter, a disinfecting device is installed (for example, a UV lamp), which allows the use of water for food purposes without boiling. The place of water filling on the site is equipped with a water filling cabinet (with a large number of users, installation of 2 or more of such cabinets is possible). Owners of apartments participating in the co-financing of this project are given a personal key for access to water bottling. Estimated cost of equipment (depending on the volume of water consumption) from 30,000-45,000 rubles. Pipe wiring, commissioning costs are calculated separately, depending on the number of entrances and the basement of a particular house.

The problem is solved in that the claimed design of a system of collective provision of residents of an apartment building with drinking water contains a pipe system, a water meter, a disinfecting device, it is distinguished by the availability of water purification means, it contains an inlet for water from the public water supply network, an outlet for distribution of purified water, while In the operating mode, water flows from the inlet to the outlet through the water purifier, and at the outlet the water purified to the level of drinking water is delivered to the water filling cabinet located in house entrance of an apartment building, providing non-stop access to the residents of apartment buildings to drinking water supply, and the cleaning means are strainer, main filter, fine filter; pressure regulator, pressure gauge for pressure control, the main filter is equipped with a flow switch having an electronic control unit, a power source, the system is fully automated. As a special case, the collective supply system for residents of an apartment building with drinking water includes a pipe system through which drinking water purified to the level is delivered to each apartment of this entrance. In addition, in the system of collective provision of residents of a multi-storey building with drinking water in order to prevent caking of activated carbon and removal of possible contaminants, the filter is periodically backwashed with source water; flushing is carried out due to the pressure of the source water, and the frequency of flushing is set using the electronic control unit. Another special case is when a UV disinfection lamp is used as a disinfecting device in a collective filtering unit.

Advantages in comparison with the prototype: the claimed support system does not require a boost pump, does not require a storage tank, which simplifies and cheapens the design and reduces the cost of the system, instead of imported water, water is used from municipal city networks (water supply), which allows round-the-clock access to residents of an apartment building In addition to disinfection, triple cleaning using filters is used, which allows its use as a drinking one.

The technical result of the claimed utility model is the creation of a simple, reliable system for providing collective round-the-clock access to drinking water of guaranteed quality from public water supply networks with transportation to the place of consumption - each entrance (apartment) of an apartment building, reducing the cost of treated water for consumers.

The technical result is achieved by the fact that the claimed design of a collective supply system for residents of an apartment building with drinking water contains a pipe system, a water meter, a disinfecting device, it is distinguished by the availability of water purification means, an inlet for water from the public water supply network, an outlet for distribution of purified water, the system has been completed at the outlet pipes, as well as a cabinet for bottling water, located at each entrance of an apartment building, providing round-the-clock access for residents of an apartment building to the drinking water appliance, while the cleaning agent is a dirt filter, a main filter, a fine filter; the system contains a pressure regulator, pressure control is carried out by a manometer; the main filter is equipped with a flow switch having an electronic control unit, a power source, the operation of the support system is fully automated. As a special case, the system of collective provision of residents of a multi-storey building with drinking water includes a pipe system for supplying water to each apartment of this entrance. In addition, in the system of collective provision of residents of an apartment building with drinking water, the washing frequency is set using the electronic control unit. Another special case when a UV disinfection lamp is used as a disinfecting device.

An example implementation:

In operating mode, water flows from the inlet to the outlet through a water purifier; cleaning agents are a dirt filter (2), a main filter (5) and a fine filter (8), pressure is controlled by a manometer (4), the main filter (5) is equipped with a flow switch (6) having a power source (7), at the same time, water from the city network goes through the purification stages in series, then at the outlet it is delivered to the water filling cabinet located at each entrance of the apartment building. During filtration through the main filter (5), water is purified from chlorine residues, chlorine by-products, soluble organic substances of natural and technogenic origin, suspended abrasive particles and a possible precipitate of iron hydroxide, while the organoleptic properties of water (taste, smell, color) are improved.

The system is fully automated and eliminates the constant presence of staff. In order to prevent caking of activated carbon and the removal of possible contaminants every 2-3 days, the filter (5) is backwashed with source water. Flushing is carried out without the use of special pumps due to the pressure of the source water. The frequency and the time to start flushing are set using the electronic control unit (6) at a convenient (for example, night) time of day. After actuation of the sorption capacity, it is necessary to replace the filter load (5). The required replacement frequency depends on the characteristics of the source water, is approximately once every 1-1.5 years and is specified during operation. After the main filter (5), water passes through a fine filter cartridge (8), in which a replaceable cartridge with a filter fineness of 3-5 microns is installed. This processing stage is intended for fine purification of water from residual suspensions. The frequency of replacement is 3-4 times per quarter. The use of a disinfecting device (9) (for example, a UV lamp) allows water to be used for food purposes without boiling. Purified water, ready for consumption, enters the pipe system for wiring along the entrances. The place of water dispensing at each entrance is equipped with a cabinet for water dispensing (10), with a large number of users it is possible to install 2 or more of these cabinets. Owners of apartments participating in the co-financing of this project are given a personal key for access to water bottling.

The quality of the treated water at the outlet according to indicators is in the interval between the first and highest category of drinking water according to SanPin 2.1.4.1116-02. "Drinking water. Hygienic requirements for the quality of water packaged in containers. Quality control. ”, Which is confirmed by the table of qualitative analysis of water before and after application of the inventive utility model (table 1, 2, 3). At the same time, the cost of treated water is much lower than purchased, packaged in a potable water tank. Estimated cost of equipment (depending on the volume of water consumption) from 30,000-45,000 rubles. Pipe wiring, commissioning costs are calculated separately, depending on the number of entrances and the basement of a particular house. The cost of one liter of purchased drinking water of similar quality is 2 rubles. 40 kopecks. For the amount of 900 rubles, you can buy 75 five-liter bottles of water (which still needs to be brought into the house).

If a month, on average, spend 30 bottles of water (5 liters per day of drinking water for cooking), then this money will last only 2.5 months. Thus, the costs of the apartment owner to co-finance the installation of post-treatment of water for the whole house will pay off in two and a half months. There is no need to carry these weights along the street, stand in line at the kiosk (in heat, frost, slush). The cost of maintaining and replacing filters for one apartment will be 45-60 rubles per month. Thus, after 2.5 months, 1 liter of drinking water at the entrance will cost residents 50-70 kopecks.
