Description

The invention relates to agriculture and can be used to disinfect the air of livestock buildings.
Known device A.S. USSR No. 1141486, MKI 3 H01T 23/00 for creating a directed ionized air flow, containing a series of parallel electrodes, which are made in the form of conductive gratings and, alternating, connected to different poles of a high voltage source, with the electrodes connected to one of these poles voltage source, equipped with conductive needles that are fixed in the nodes of the lattices of these electrodes on surfaces facing the subsequent electrodes of the specified row, the remaining electrodes connected to the other pole of the voltage source, in addition to the extreme electrode, is also provided with conductive needles fixed in the nodes of their gratings on surfaces facing the smooth surfaces of adjacent electrodes.
The disadvantage of this device is the low speed of the created air flow due to the different polarity of the corona electrodes. The low speed of the created air flow causes a low productivity of the device, which leads to an increase in their number for processing a given volume of the room.
Closest to the proposed device is the ion filter fan of the Russian Federation No. 2181466, IPC 8 7 F24F 3/16, B03C 3/09, containing a corona negative electrode installed at the input and non-corona and precipitation electrodes located behind it, enclosed in a housing and electrically connected with high voltage source. The corona negative electrode is made in the form of a grid, in the nodes of which there are needles perpendicular to its plane, directed to a non-corona electrode made in the form of a grid of metal wire with a mesh size of 20 mm and installed at a distance of 35 mm from the needles, behind it there are precipitation electrodes, made in the form of plates with a length of 170 mm located perpendicular to the non-corona electrode and parallel to each other at a distance of 18 mm, while the even and odd plates are electrically connected to each other.
The disadvantage of this ion filter fan is the low speed (v = 1.2 m / s) of the generated air flow at a voltage of U = 18 kV, which leads to low productivity in terms of the volume of the processed air medium, as well as the high cost of the high-voltage power supply.
The objective of the invention is to increase the productivity of the device by the volume of the medium being processed, as well as reducing the cost of a high-voltage power supply.
The solution to this problem is achieved by the fact that an ion-filter fan containing a corona negative negative electrode installed at the input, non-corona electrodes and precipitation electrodes located behind it, enclosed in a housing and electrically connected to a high voltage source, moreover, a non-corona electrode is installed from corona needles on a distance of 20 mm and is made with cells 10 × 10 mm in size, even flat deposition electrodes 130 mm long are connected to the negative potential of the high voltage source and can be used on one side with the tips, in addition, an additional non-corona mesh electrode with 10 × 10 mm cells is installed, which is attached to an odd flat sedimentation electrodes 170 mm long and connected to a positive potential and installed at a distance of 20 mm from even flat sedimentation electrodes .
The invention is illustrated by drawings (1, 2).
Figure 1 shows schematically the device of the ion filter fan.
Figure 2 presents a graphical dependence of the electric wind speed on the area of the cells of the mesh electrodes.
The ion-filter fan consists (Fig. 1) of odd flat precipitation electrodes 1 with a length of 170 mm, even flat precipitation electrodes 2 with a length of 130 mm, a corona net negative electrode 3 with corona needles 4 and non-corona net electrodes 5, 6 attached to both sides to the flat precipitation electrodes 1. The electrodes 1, 2, 3, 5 are enclosed in a housing and are electrically connected to a high voltage source. The power of the corona wire mesh electrode 3 with needles 4 and even flat electrode plating electrodes 2 is supplied from the negative potential of the high voltage source, and the power of the odd flat electrode electrode 1 and non-corona mesh electrode 5, 6 is supplied from the positive potential of the high voltage source, in particular 10 kV .
The proposed device is installed in livestock buildings. In particular, at a voltage of 10 kV, the discharge gaps between the corona needles 4 of the negative mesh electrode 3 and the non-corona mesh electrode 5, between the even flat deposition electrodes 2 and the additional non-corona mesh electrode 6 are 20 mm.
The proposed device operates as follows.
In the discharge gap between the corona needles 4 of the corona negative net electrode 3 and the non-corona net electrode 5 under the action of high tension, ionization processes occur at the tips of the needles. Negative ions and electrons formed will move under the influence of Coulomb force from the needles 4 to the non-corona mesh electrode 5. Faced with neutral air molecules and dust particles, they transfer part of their energy to them and in this way electric wind is formed (air mass movement) . Charged dust particles are deposited on flat precipitation electrodes 1, 2 and then the air moves, already cleared of dust particles. Getting into the discharge gap between even flat deposition electrodes 2 and an additional non-corona mesh electrode 6 with 10 × 10 mm cells (Fig. 2), the air medium again undergoes ionization and dissociation processes, as a result of which the flow velocity increases to 2.4 m / s, and O 3 O 3 molecules are also formed. At the output of the non-corona mesh electrode 6, we have an ozone-air mixture, which is fed into a room where decontamination and deodorization of the air occur due to ozone.
