Description

The invention is intended for bacterial purification of circulating and intake water of life support systems in installations of recirculating water supply systems and is an integral part of it.

A device for bactericidal non-thermal treatment of a liquid medium in a stream is known, containing inlet and outlet pipes, an extended source of ultraviolet radiation, external and internal cylindrical elements installed with an annular gap to pass the medium in the axial direction, the cylindrical elements are made with the possibility of periodic asymmetric changes in the thickness of the annular gap by mutual movement, and/or vibrations, and/or rotation in a plane perpendicular to the longitudinal axis. This device provides an increase in productivity, more efficient cleaning of the structural elements of the sterilizer (patent RU 2322937). This device has a rather complex design, is prone to contamination, which reduces the quality of sterilization, reduces the life of the device.

Known sterilizer, including a body in the form of a cylinder, mounted in a central position parallel to the side surface of the cylinder, an elongated source of ultraviolet radiation and installed around it parallel to the side surface of the cylinder tube for the passage of water, which improves the efficiency of sterilization (patent CN 2422275). The design of the device does not contribute to its long-term maintenance-free operation.

A well-known sterilizer includes a cylindrical body with an inlet tube for water inlet and an outlet tube for the output of treated water, ultraviolet LEDs installed inside the case, and a quartz flask with a gap between the inner walls of the case and the outer walls of the flask, to create a laminar water flow in a thin tangential vortex layer, the inlet pipe for water supply is connected tangentially to the upper part of the body, and the outlet pipe is tangentially connected to the lower side part of the body and in the form of a coil, it is passed through the lower base of the body. This device improves the efficiency of sterilization (patent RU 2708585). The device, due to its design features, is prone to contamination, which reduces the quality of sterilization and reduces the life of the device.

As the closest analogue, you can make a decision on RU 2708585.

The technical problem is insufficient efficiency, insufficient service life of devices due to their pollution.

A sterilizer is proposed, which includes a cylinder-shaped body, sources of ultraviolet radiation. An inlet branch pipe is installed from the side surface of the cylinder body at its upper base. An outlet pipe is installed in the center of the upper base of the cylinder. Between the outlet pipe or the outlet tube and the side wall of the cylinder, parallel to the side wall of the cylinder, elongated sources of ultraviolet radiation are installed.

In a particular case, the sterilizer includes an air vent system. The air release system can be a manual or automatic air release valve.

In a particular case, the sources of ultraviolet radiation are flasks.

In a particular case, the sources of ultraviolet radiation have equal length, equal diameter, are located uniformly, at the same distance from the axis of the cylinder and at the same distance from each other.

In a particular case, sources of ultraviolet radiation of different lengths.

In a particular case, the sterilizer includes at least five sources of ultraviolet radiation.

The technical result is a high efficiency of the device, a long service life of the device by reducing pollution sources of ultraviolet radiation.

A possible embodiment of the invention is shown in Fig.1, 2.

Figure 1 shows the device in longitudinal section.

Figure 2 shows a top view of the device.

The positions in the illustrations are:

1 - body,

2 - sources of ultraviolet radiation,

3 - inlet pipe,

4 - outlet pipe,

5 - air release valve.

Centrifugal sterilizer works as follows.

1. The maximum residence time of the liquid in the zone of treatment with ultraviolet radiation is ensured due to the design of the unit.

The liquid, entering through the inlet pipe (3) into the cavity of the cylinder (1) of the sterilizer at an angle, creates turbulence, the centrifugal force does not allow the liquid to pass the minimum path to the outlet (4), which contributes to an increase in the efficiency of the ultraviolet emitters (2).

2. Due to the maximum stay of the liquid in the UV treatment zone, the installation is less energy intensive, which reduces energy consumption.

3. Due to the centrifugal force and turbulence created by the pressure of the liquid in the sterilizer cylinder, the bulbs of ultraviolet emitters are less exposed to contamination and increase the period of operation without maintenance, without reducing the efficiency of the unit.

4. To ensure the proper operation of the device, proper sterilization and achieve a technical result, an air discharge system is provided, this system will be necessary in the case of non-pressure supply of liquid to the sterilizer, in order to avoid airing the system. The air release system can be a manual or automatic valve (5).

5. The geometry of the sterilizer provides the condition for creating the maximum effect in the biological treatment of liquids with minimal energy consumption and maintenance.

6. The sterilizer is safe for any hydrobionts and people, it can be used in rooms with high humidity.

Sources of ultraviolet radiation can be made of different lengths, which creates additional turbulence during the movement of the liquid and can enhance the achieved technical result: longer service life, higher efficiency of the sterilizer.

To achieve proper sterilization, a minimum of five ultraviolet sources are required, and their number can be more.

The device provides high sterilization efficiency, high efficiency, the service life of the device is significantly increased, since there is no pollution of radiation sources.
