RU211032U1 - Bactericidal Air Purification System - Google Patents

Abstract

The claimed technical solution relates to a device for sterilization and bactericidal air purification using ultraviolet radiation. The utility model is a gas pipeline with air inlet and outlet. The calculated geometry of the product in the form of an elongated cylindrical shape creates an aerodynamic flow that sets the direction and speed of air movement. The main feature is that inside the gas pipeline there is a turbulator with ultraviolet LEDs both on it and on the gas pipeline. The technical result of the utility model is that the existing helical spiral slows down the air flow. Thanks to this design, LEDs treat the air with ultraviolet light for a long time. This solution allows to achieve a high degree of air purification in the room. A multi-level system of slowing down and swirling the gas mixture allows you to evenly process the air flow, avoiding the formation of low irradiance zones. In addition, the utility model has special mounts that allow you to attach it to any ventilation and air conditioning systems, as well as use it as an independent air purification system. The presence of fasteners also leads to another advantage: the absence of a fan, since the utility model is attached to air conditioning and ventilation systems and does not require increased air movement. The bactericidal air purification system has a compact size, and from this it follows that the claimed model can be used in various fields: both for commercial, domestic premises, and in industry.

Description

1. Technical field

The claimed utility model relates to a device for sterilization and bactericidal air purification using UV radiation. The task of this device is bactericidal air purification by introducing the device into the existing air ventilation system in the room using a source of ultraviolet light.

The utility model is an integrated purifier that, firstly, separates the air streams entering the ventilation and, secondly, disinfects these streams with ultraviolet radiation using LEDs that destroy pathogens.

2. State of the art

Traditionally, air purifiers are a device that is installed indoors and purifies the air. Such a system uses a fan, filters, UV lamps, including mercury lamps and LEDs. All such systems operate independently of ventilation and air conditioning systems that already exist and are used in buildings, premises, and transport.

3. The essence of the utility model

The purpose of the present utility model is to provide an air purifier with a germicidal effect, including a source of ultraviolet light, into which the ventilation or air conditioning system draws in outside air, and the turbulator slows down and cleans the air flows. Thanks to this design, air flows that enter the purifier through the air capture systems of the ventilation system are slowed down in the purifier itself and are cleaned.

The utility model is an elongated cylindrical gas pipeline with a length of 400 to 1000 mm and a diameter of 32 to 50 mm. This shape creates an aerodynamic flow that sets the direction of the air. Along the edges of the gas pipeline there are openings for the entry and exit of air flows. These openings are located in such a way that air enters the air purification system, is disinfected and exits through an opening located at the other end of the gas pipeline, rotated by 180°, which is closely adjacent to the ventilation system. Thus, untreated air flows enter the bactericidal air purification system through the inlet, pass through the purification system and enter the ventilation system already cleaned.

The deceleration of air flows passing through the cleaner is carried out using a turbulator. This design of slowing down and swirling the gas mixture allows you to evenly process the air flow, avoiding the formation of low irradiance zones.

Inside the bactericidal air purification system there are ultraviolet LEDs, which can be located both on the turbulator and on the gas pipeline up to the air outlet. The combination of slow air flows and their treatment with several sources of UV radiation creates the possibility of a high degree of purification from pathogens. This gives, firstly, an increased coefficient of utilization of the bactericidal flux of diodes of 0.7, which means that a large proportion of UV radiation is spent on the destruction of microorganisms. Secondly, the utility model has a high germicidal radiation intensity of at least 1000 mW/cm ² .

The bactericidal air purification system has fasteners, with the help of which the structure is fixed on the ventilation grille. There must be at least 2 fasteners, which are located at the inlet and outlet.

The utility model is powered by electricity, so the cleaner needs an external power supply. At one end there is a detachable plug for connecting to this power supply.

4. Description of drawings

In FIG. 1 schematically shows a general view of a bactericidal air purification system, which is a housing with a diameter of 32 to 50 mm and a total length of the housing from 400 to 1000 mm with an inlet (2) and outlet (1) opening in it, with an air turbulator in the form of a helical spiral, and also shows where the side cover is attached.

In FIG. 2 shows a general view of the turbulator located inside the housing. It has a spiral shape, which allows you to separate and slow down the flow of air.

In FIG. 3 shows the front view: the outer side and the inner side of the purifier.

The housing (3) contains an inlet (2) opening where air masses enter, an outlet opening from where the disinfected air masses enter the ventilation or air conditioning system. The housing is closed with side covers (4). The air masses are separated and slowed down by the turbulator (5). At the same time, LEDs (6) are located on the wings of the turbulator, which disinfect the air masses.

In FIG. 4 shows a right side view. The side of the bactericidal air purification system is closed with a side cover.

In FIG. 5 shows a top view.

The air masses that enter the inlet (2) pass through the turbulator (5), where they are slowed down by it, due to which the air is disinfected (subjected to a higher degree of purification by means of ultraviolet LEDs located on the flow turbulator up to the air outlet), and enters the ventilation and air conditioning systems through the outlet.

5. Implementation of the utility model

The bactericidal air purification system can primarily be used to clean and disinfect the air of buildings and premises. It can be installed in the ventilation or air conditioning system of residential premises, offices, warehouses, etc.

Also, the system can be used to clean and disinfect the air in transport when it is introduced into the ventilation and air conditioning system. The use of the claimed utility model will be useful both when installed in vehicles with a large number of people (train, plane), and when installed in private vehicles, for example, a car and a fixed-route taxi.

The bactericidal air purification system has a compact size, and from this it follows that the claimed model can be used in various fields: both for commercial, domestic premises, and in industry.
