Description

 The invention relates to the treatment of industrial, domestic and wastewater, and more particularly to the design of devices for disinfecting water using bactericidal radiation.

 The device can find predominant use in the disinfection of large quantities of water flowing at high speed from the point of intake into a closed container, for example, when taking ballast water to a vessel to improve its seaworthiness and drinking water supply.

 A device for disinfecting water is known, comprising a housing with inlet and outlet tubes, an ultraviolet germicidal lamp inserted in a protective cover made of quartz glass, which is placed inside the housing with the liquid circulating in it, and an ejector through which air is formed through the passage of air through ultraviolet radiation ozone is utilized, soluble in water and improves the quality of treated water.

 The disadvantages of this device include the lack of mixing of the layers of water in the flow chamber, which significantly reduces the efficiency of the sterilization process, and the fact that the design of the housing allows precipitation to the bottom and is not able to ensure the passage of a large volume of water in a short period of time, as this the lack of energy of the bactericidal lamp installed in the middle of the body prevents it.

 The aim of the present invention is to intensify the disinfection of large volumes of water in a short period of time.

 This object is achieved in that the device for disinfecting water, comprising a housing with a flow chamber, an ultraviolet germicidal lamp mounted in a protective sealed quartz glass case, and inlet and outlet tubes are provided with additional ultraviolet germicidal lamps mounted radially in the protective case, placed in the flow chamber, made in the form of a glass with a central conical nozzle, the cone of which is directed to the place of water intake, and is located hydrochloric coaxially with respect to germicidal lamps, while between the outer surface of the protective cover and the inner surface of the housing there is a gap sufficient for the flow of calculated quantity of water to be treated.

 In addition, the outer surface of the nozzle and the inner surface of the housing are made of material with high reflectivity. In addition, the protective quartz case is provided with air supply and exhaust pipes, while the air supply pipe is connected to a source of cooling air.

 In addition, the device is equipped with a pipeline with a system of holes along its length, mounted on the end of the housing at the location of the tube that takes air from the cover and connected to it.

 Figure 1 shows a diagram of a device for disinfecting water; figure 2 is a section aa in figure 1.

 The device for water disinfection consists of a housing 1 made in the form of a cylindrical hollow casing, equipped with a conical nozzle 2 in the central part, which has a spiral groove system on the outer diameter, due to which the fluid, when passing with great speed along the outer part of the nozzle, acquires a rotational movement along the nozzle and thereby there is a process of intensive mixing of it. Between the inner diameter of the casing 1 and the outer surface of the nozzle 2, a protective sealed cover 4 is made of quartz glass, in which bactericidal lamps 5 of ultraviolet radiation are radially mounted. For better cooling, the lamps can be separated from each other by partitions 6 mounted on the lower and upper ends of the cover in a checkerboard pattern with a gap for the consecutive flow of air from one section to another. The cover 4 contains inlet 7 and outlet pipes 8, while air is supplied to the inlet pipe 7 to cool the bactericidal lamps 5, and through the outlet pipe 8 connected by one side to the cover 4 and the other to the end of the hollow casing 1, in which the atomizer is mounted air 9, ozonated gas is received resulting from the ionization of oxygen in the air passing along the bactericidal lamps 5.

 The sprayer may be a hollow pipe with a large number of small holes along the length. On the other hand, the cooling of the lamps 5 is also carried out by running water washing the inner and outer surfaces of the cover 4. Between the surfaces of the casing 1 and the cover 4, a sufficient gap is left in which running water circulates. For a more complete use of the light energy of the lamps 5, the outer surface of the conical nozzle 2 and the inner surface of the cylindrical casing 1 are made with high reflectivity, for example, the nozzle is reinforced with polished stainless steel.

 The entire device is placed in a receiving protective chamber, which contains a kingston for receiving water inside the chamber and a piping system for pumping it with pumps to storage sites.

 The device is mounted in the immediate vicinity of Kingston using fasteners 10, which, in turn, must be equipped with a self-cleaning filter that prevents foreign particles, living organisms and various debris from entering the water.

 A device for disinfecting water works as follows.

 When you turn on the pump, water 3 from a reservoir, such as a river, through Kingston under pressure will begin to flow into the chamber. Due to the fact that the Kingston hole is coaxial with the flow chamber, which is the inner diameter of the protective cover 4, which is permeable to ultraviolet radiation from radially located bactericidal lamps, the water flowing between this casing and the conical nozzle 3 is subjected to intense radiation. Due to the presence of screw grooves on the nozzle, the water receives a rotational movement relative to the flow chamber and thereby it is mixed and irradiated with new portions of the flowing liquid. The presence of a conical nozzle 2 in the hollow casing 1 and installation of the cover 4 in the resulting space causes the fluid flow to reverse its direction of motion and flow out in the gap formed between the outer diameter of the cover 4 with bactericidal lamps and the inner surface of the casing 1, again subjected to intense ultraviolet radiation. A sufficient clearance is selected to pass the calculated amount of the treated water so that the entire volume can be treated with ultraviolet light.

 The air entering through the inlet tube 7 into the case 4, passing sequentially between the lamps 5, is ionized and through the outlet tube 8 enters the atomizer 9, mounted on the end of the casing 1 at the outlet of the flow of disinfected water into the chamber. In the place of the speed difference, a reduced pressure arises at the outlet of the water flow from the device, where the ozonized gas bubbles come from the atomizer, which, mixed with water, makes the final sterilization of the water. If it is necessary to disinfect large volumes of water for a short time, when for technical reasons one proposed installation is not able to process the entire amount of water, it is possible to use additional identical devices that are installed either in parallel or in series with each other. It is also possible to install them along the technological chain, for example, in the receiving port of Kingston, in front of and after the suction pump.

 The technical and economic advantages of the proposed device for water disinfection are to increase the efficiency of water treatment due to the integrated treatment (ultraviolet irradiation and ozonation), as well as the ability to disinfect a large amount of water for short periods of time by increasing the intensity of light irradiation and increasing its efficiency use.
