Description

The proposed utility model relates to physicochemical technologies and water treatment techniques. The invention can be used in industrial production of high quality water.

A well-known complex of equipment for implementing the method of preparing bottled oxygenated drinking water [German Patent No. 1047826 Production of long-term drinking water bottled in a bottle saturated with oxygen in the form of air (oxygen and carbon dioxide), С02F 1/68 (NKI BG7D 1/00 H 4 C), 10.16.1998].

A set of equipment for implementing this method includes an installation for saturation of drinking water with oxygen, consisting of series-connected storage pressure vessels (columns) for collecting and treating water with oxygen-containing gas under pressure, auxiliary equipment for maintaining overpressure and reduced temperature in an oxygen saturation unit, a bottling installation and blockages of oxygenated water in a bottle connected by a pipeline to the oxygen saturation of drinking water ohm

The disadvantages of the equipment for implementing the method:

- high energy intensity and material intensity of the equipment for the saturation of drinking water with oxygen;

- the possibility of microorganisms entering during bottling of oxygenated water in bottles and when sealing them with stoppers (bottles are disinfected from microorganisms before the bottling operation);

- the possibility of ignition in oxygen at overpressure of engine oil, the vapors of which can get from auxiliary equipment into the oxygen saturation of drinking water.

Known installation for implementing a method for the preparation of oxygenated drinking water in industrial production

bottled water [US Patent No. 6,284,293 Method for the production of oxygenated water. B1 A23L 100 (NKI 426/67) 09/04/2001].

In the installation, the saturation method consists in mixing an oxygen-containing gas with treated chilled water under pressure in order to obtain an oxygen-saturated state of the treated water. When implementing this method, drinking water is pre-treated with reverse osmosis and electrolysis.

Energy-intensive physicochemical processes are used in a water oxygen saturation unit to increase the stability of a water-supersaturated state of water by reducing the concentration of salts in water and introducing charged H ₂ + O ₂ electrolysis gas into the water.

Known physico-chemical methods of pre-treatment of drinking water have several disadvantages:

- water electrolysis causes contamination of drinking water with electrolysis products (active chlorine, heavy metal ions);

- desalination of water by reverse osmosis to the level of distillate negatively affects the cells of the esophagus (causes their osmotic shock).

The closest in technical essence and the achieved effect is the installation for oxygenation of drinking water or soft drinks (Publication number of the invention 98116606 A23L 2/00, A23L 2/00, Registration number of the application 98116606/13, Date of publication 2000.06.20.), Including capacity , the shape of which can be made in the form of a cylinder, ball, cone, pyramid, cube or parallelepiped, or which can be used as an installation for carbonization of drinking water or soft drinks, equipped with nozzles for feeding, draining gas and gas supply, while the tank is connected to a closed loop of pipelines, to which a centrifugal pump is additionally connected, the suction pipe connects the bottom of the tank to the pump, the discharge pipe connects the top of the tank to the pump, the suction pipe is connected to the pipe to drain liquid from

containers, the discharge pipe is connected to a pipe for introducing liquid into the container, a pipe for supplying gas is equipped with a suction pipe, and the installation is equipped with an additional pipe connecting the upper part of the container with a suction pipe.

The technical task of the utility model is to reduce energy costs for the preparation of oxygenated drinking water by increasing the efficiency of the saturation process, rational organization of the process with obtaining a stable product and high reliability of the installation.

The stated technical problem is achieved in that in the installation for the preparation of oxygenated drinking water containing a water treatment system and a saturation system including a tank equipped with nozzles for supplying, draining liquid and supplying gas, characterized in that the tank is connected to a closed loop of pipelines, to which is additionally connected centrifugal pump new is that the discharge pipe is connected to the nozzle for saturation of water with oxygen, and the outlet pipe from the nozzle for saturation in The ode is equipped with a viewing cylinder to control the saturation process and is connected to the tank in the form of a cylindrical chamber coaxially mounted inside the aeration column, which is connected by a recirculation pipe to the suction pipe.

The technical result of the utility model is to reduce energy costs for the preparation of oxygenated drinking water by increasing the efficiency of the saturation process, rational organization of the process to obtain a stable product and high reliability of the installation.

In Fig.1 shows a diagram of the installation for the preparation of oxygen-saturated water, Fig.2 is a diagram of a nozzle for saturation of water with oxygen.

Installation for the preparation of oxygenated drinking water (Fig. 1) includes a bag filter (for example, RVN-4200) of high performance (138-188 l / min), a lid, a housing, a basket, a ventilation plug, and a drain plug which are made of polypropylene. At the same time, interchangeable elements are located in the baskets of the bag filter.

To improve the taste and smell of drinking water and remove organics from the water, a sand filter (for example, CAS series) is provided in the oxygenated drinking water preparation unit, which consists of two technical devices: a control mechanism and columns with filtering quartz sand.

To soften the water and remove dissolved iron, an ion-exchange installation is intended, which includes: a control mechanism (not shown), two ion-exchange columns 3 and a tank for the regenerating salt solution 4.

After the ion-exchange installation, bag-type filters 5 and a buffer tank 6 made of stainless steel are installed in series.

Next, the buffer tank 6 is connected to the saturation system with a pipeline consisting of a suction 7 and discharge 8 pipelines, separated by a centrifugal pump 9.

The discharge pipe 8 is connected to a nozzle 10 for saturation of water with oxygen, the supply of which is through a pipe 11 connected to an oxygen cylinder 12 and equipped with a check valve 13 and valve gearboxes 14 (for example, grade 122-12UHL 4).

The outlet pipe 15 from the saturation nozzle 10 is equipped with a viewing cylinder 16 for controlling the saturation process and is connected to a cylindrical chamber 17 coaxially mounted inside the aeration column 18. To return the excess oxygen from the aeration column 19, a recirculation pipe 19 connected to the suction pipe 7 is used.

To disinfect the water sent to the bottling in the pipeline 20 emerging from the aeration columns 18 installed bactericidal lamp 21.

The nozzle 10 for saturating water with oxygen includes a housing 22, inside of which a candle titanium filter having a porous structure and secured with a clamp 25 is mounted on a perforated nozzle.

Installation of oxygenated drinking water works as follows.

The technological process in the installation should be carried out in compliance with the "Sanitary norms and rules for enterprises of the brewing and non-alcoholic industry", approved in the prescribed manner and in accordance with the installation scheme for the preparation of oxygenated drinking water (figure 1).

Tap water from the network enters the pumps (not shown) and is pumped under a pressure of 4-6.2 MPa into a bag filter 1 (for example, RVN-4200) of high performance, where it is filtered to separate coarse impurities.

After the bag filter 1, water is supplied at a pressure of 0.21-0.86 MPa to the sand filter 2 to improve the taste and smell and remove organics.

Then the water enters the ion exchange unit at a pressure at its inlet of at least 0.2 MPa to soften and remove dissolved iron in the ion exchange columns 3.

Softened water enters the bag-type filter 5 and then into the buffer tank 6, from which it enters the nozzle 10 using a centrifugal pump 9 to saturate it with oxygen at a pressure of 0.15-0.2 MPa, where oxygen is dissolved in water to the saturation level not lower than 40 mg / dm ³ , and then into the aeration column 18 to maximize the use of oxygen and reduce its losses. To do this, the excess oxygen from the aeration unit 18 is returned through a recirculation pipe

19 to the pressure pipe 7, where insoluble oxygen is supplied to the nozzle, where it is dissolved in water.

Water saturated with oxygen from the aeration column 18 and disinfected when passing through a bactericidal lamp 21 is sent to the bottling.

The advantages of the proposed installation are to reduce energy costs for the preparation of oxygenated drinking water by increasing the efficiency of the saturation process, rational organization of the process to obtain a stable product and high reliability of the installation.
