Method of air purification
SUBSTANCE: purified air is supplied through the pipe 2 to the upper chamber 9 of the housing 1. At that, passing through the discharge electrode 13 the air is ionised and it charges the dust that is in the air. The charged dust particles move in the direction to the electrodes 6 having a positive potential which turn conjointly with the wheel 4. Having reached the surface of the electrodes, the particles are deposited on them. When the wheel 4 reaches the position when the upper blades are located symmetrically relative to the vertical axis, in the chamber 9 an enclosed volume is created, which is limited by the blade-electrodes and the upper part of the housing 1. In this volume the air portion is finally purified and the noise accompanying the purified air is reduced. Simultaneously the third blade-electrode holds the lower vertical position in the chamber 10 where it is freed from contaminants by feeding to the electrode and the rollers 7 of the similar high potential.
EFFECT: simplification of the design that implements the method and increase of effectiveness of the degree of air purification, reduction of the noise level.

The invention relates to the cleaning and disinfection of air and can be used for ventilation of various premises clean air.
There is a method of air purification from dust and aerosols, including the formation of positively charged ions of nitrogen and oxygen by exposure to the air stream by corona discharge, polarization electrostatic dust and aerosol particles with subsequent removal of their precipitation electrodes [U.S. Pat. RF 2182850, IPC7VS 3/00, 2002].
The disadvantages of this method are:
- complexity designs, implements the method, due to the presence of a large number of elements;
- inconvenience in operation, due to the need periodical cleaning of the collecting electrodes from dust and dirt;
- a relatively large resistance to air flow a large number of elements, which requires additional energy to overcome the resistance.
The prototype is the way to clean air, including a location in the air stream discharge and precipitating electrodes placed rows to the stream and having different electrical potential, polarization electrostatic dust and aerosol particles with subsequent removal of their precipitating electrodes [U.S. Pat. RF 2313732, IPC F24F 3/16, 2007]. The disadvantages of the prototype are:
- is very useful in controlling the speed of the air flow, because the rate depends on the number of electrodes and the potential for them;
the dependence of the quality of cleaning air from the flow velocity due to, firstly, the possible leakage of particles of the electrodes at high speed and, secondly, the number of these electrodes;
- at high speeds the air flow created by fan in polluted electrostatic precipitator there is a danger of blowing the earlier part of the settled dust and cleaning efficiency may decrease;
- inconvenience in operation, due to the need periodical cleaning of the collecting electrodes from dust and dirt and the presence of noise, freely passing with the air flow.
The invention aims to remedy these disadvantages, namely the simplification of the structure that implements the method, and improved performance.
The task is solved in that in the method of cleaning air comprising a location in the air stream discharge and precipitating electrodes having different electrical potential, cleaning produce portions in a confined space, part of which is made of a precipitating electrodes, and after cleaning the precipitating electrodes placed in the chamber, where they are free from contamination.
The release of the camera is produced by feeding on the precipitating electrode larger capacity than the eyes is TCE. Upon release to the electrode and the chamber wall serves the same potential. Upon release in turn serves the potential of both characters. Part of the chamber are in the form of the accelerating electrode, which is compared with the release from contamination electrode serves opposite in sign to the potential. Part of the walls of the chamber are in the form of a spark gap. The surface of the volume of cover material of polyacrylonitrile. The noise that accompanies the cleaned air, quenched in a confined space.
These distinctive features can achieve the following advantages in comparison with the prototype.
The clearance portions in a confined space, part of which is made of a precipitating electrodes, allows to clean the air of impurities, as limited by the vortex motion of the air is completely stopped, and the dust freely attracted to the electrodes. This improves the quality of air purification.
The room after cleaning precipitating electrodes in the chamber and release there from contamination allows you to constantly keep them clean, eliminating the need for periodic maintenance of the filter, which improves performance.
Release the camera from contamination by feeding on the precipitating electrode larger capacity than the cleaning, allows to simplify the design that implements the method.
Filing with the release on the electrode and the chamber walls the same potential to simplify the design and prevents contamination of the chamber walls, which improves performance.
Filing with the release alternately potentials of both characters allows you to more efficiently clean the electrode from contamination with different charges, which improves performance.
The execution of the camera as an accelerating electrode, which is compared with the release from contamination electrode serves opposite in sign to the potential, prevents the pollution of the camera, so as remove the dirt leaving the camera in a specific direction determined by the accelerating electrode, which improves performance.
Part of the chamber wall in the form of a spark gap facilitates automatic cleansing of the accelerating electrode in the case of contamination, which improves performance.
Coating the surface of a volume of material of polyacrylonitrile improves the quality of air purification. First, this material will neutralize small amounts of ozone that can be generated by corona discharge, resulting, ultimately, is formed healthy composition in the spirit. Secondly, the elements of the device air purification longer will not fail due to exposure to ozone, which prolongs their service life. All this improves performance.
Damping of the noise accompanying the cleaned air in a confined space contributes to the rapid attenuation of the sound wave, which improves performance.
The invention is illustrated in the drawing.
The figure shows a diagram of a device for cleaning and air injection.
The device includes a housing 1 with an inlet 2 and outlet 3 nozzles for air, which is rotatably mounted the wheel 4 is electrically separated by a gap 5 blades-electrodes 6 kinematically associated with the rollers 7 having recesses 8 for the passage of the blades. Videos share the building at the top 9 of the camera and the bottom 10 in which may be placed accelerating electrode 11 and the spark gap 12. Inlet pipe has a discharge electrode 13.
The method is implemented as follows.
Designed for cleaning the air supplied through the pipe 2 into the upper chamber 9 of the housing 1. While passing through high (e.g., negative) potential electrode 13, the air is ionized, negative air ions charge (or recharge) the dust and the microflora that are in the air, up to a certain potential. The charger, side buttons is by dust particles or microorganisms begin to move towards having a positive potential to the electrodes 6, which rotates along with the wheel 4. Wheel and interacts with the rollers 7 can be driven by the engine or the pressure of air entering the pipe 2.
Reaching the electrode surface, the particles settle on them. With the approach of the wheel 4 to the position where the upper blades are arranged symmetrically relative to the vertical axis in the chamber 9 is formed a closed volume bounded by the blades-electrodes and the upper part of the housing 1. In the resulting closed volume portion of the air is purged, because in this volume do not penetrate the contaminated air, and missing all kinds of air turbulence. In addition, the rapidly attenuated in this volume and the sound waves are repeatedly reflected from the walls, resulting in reduced noise.
At the same time the third blade-electrode occupies the lower vertical position in the chamber 10. To free it from impurities it serves more than when the air cleaning capacity. As a result, dust particles with a positive charge, fly away from the electrode. The rollers 7 at this point serves the same potential, so that dust particles cannot approach the rollers and in the form of a cloud moving in the direction of the accelerating electrode 11 with the opposite (negative) potential, and are removed from the ka is a career 10. This potential can be provided on the entire surface of the roller 7, and only the part, which at this point is addressed to exempt from dirt shoulder. It should be noted that in the presence of air particles formed of poorly conducting electricity materials, may occur, their adhesion to the electrode 6 without loss of electric charges. Therefore, to release the electrode located in the chamber 10 after the positive potential on it and the roller 7 serves a negative potential, due to which the electrode is released from dirt completely and then enters the chamber 10 of the housing 1 for receiving and cleaning the next portion of the air. It should be noted that the camera 9, which moves the air from the inlet pipe 2 to the outlet 3, always covered, at least one blade-electrode 6, so always provides a barrier to the penetration of sound waves (noise) through the air cleaner in the room.
The presence on the high potential electrodes and alternately change their characters detrimental effect on the incoming air to the microorganisms and bacteria that are killed.
Over time on the accelerating electrode may be formed clot of dust, which will prevent the output from the camera 10 to be deleted from the electrode contamination. To clean the accelerating electric is Yes the walls of the chamber are in the form of a spark gap 12. The accumulation of dust on the accelerating electrode, the gap between him and the discharger will be reduced and, in the end, it will be a break of the high voltage with the formation of a shock wave, which will reset the accumulated bunch of dust from the accelerating electrode. Supply the right is the sign of the potentials on the electrodes in the desired position can be produced by a known method, for example by means of a header.
Implementation of the invention will create a simple design of the device for air cleaning, which thanks to the continuous purification requires no maintenance and can be supercharged.
