Abstract

The invention improves air cleaning efficiency. The positive electrode (E) 14 is made in the form of a C-shaped plate with separation windows 15 and is connected to a current source 18 insulated from the case 1. Negative E 12 with current-supplying needles I3 and perforations is located around the annular filter element 9 and is connected to ground. In the inlet radial nozzle 2 along its axis there is a plate 19, the side of which from the side of element 9 has a saddle shape and is connected to E 14, forming a ring. On the walls of the inlet 2 around the plate 19 there is an additional negative E 21. Both the E 12 and 21 are made in the form of a conductive fuzzy fibrous material, for example a fibrous carbon graphite. The negatively electrified large and medium dust particles are attracted to the plate 19 and settle to the bottom. The fine dust particles are additionally in contact with 312, are also attracted to the E 14, and dust accumulates on the bottom, and the air through the element 9 enters the engine intake duct. 4 il. i (L

The invention relates to mechanical engineering, primarily to engine building, in particular to air purification devices.

The purpose of the invention is to increase the cleaning efficiency.

Figure 1 shows the air cleaner, General view; in Fig.2 is a section aa in Fig.I; FIG. 3 shows positive and negative electrodes in a disassembled state; figure 4 is a plate and a fragment of an additional negative electrode located on the walls of the inlet nozzle, cross section.

The air cleaner consists of a cylindrical body 1 having a radial inlet nozzle 2, a bottom 3 with an axial outlet nozzle 4, an upper 5 and a lower 6 cover, fastened with a bolt 7 with a nut 8, an annular filter element 9 with elastic pads 10 and 11. Around the filter element 9 the negative electrode 12 is located, exuberant in the form of a ring and made of a conductive fleece fibrous material, for example, a fibrous carbon graphite, the fuzzy ends of which are located on the outside and form ozhestvo conductive needles 13.

Between the housing 1 and the negative electrode 12 there is a positive electrode 14, made in the form of a C-shaped plate and equipped with separation windows 15. The positive electrode 14 is fixed on insulators 16 and connected through insulator terminals 17 with a positive current source 18, minus of which is connected to mass and housing 1. Inside the inlet nozzle 2 along its axis there is a plate 19 of conductive material. The plate 19 on the side of the filter element 9 has a saddle shape and is connected to the positive C-shaped electrode 14 with the help of brackets 20, forming a ring. On the walls of the inlet 2 around the plate 19 there is an additional negative electrode 21, which, like the negative electrode 12, is made of a conductive fuzzy material, the fuzzy ends of which form a plurality of needles 13 and are directed inside the socket 2. At the bottom 3 and in

The lower end 6 is made of perforated windows 22 and 23, which do not overlap each other when the air cleaner is operating.

The air cleaner works as follows.

Atmospheric air enters the inlet pipe 2 of the air cleaner and the passage between the plate 19 and SL

The current-carrying fuzzy fine-fiber material of the additional negative electrode 21 is subjected to a high-voltage electric field from a DC source 18. Moreover, all the particles of the contamination are intensively electrified. In addition, the air in the nozzle 2 is ionized by negative ions, which intensively flow in the zones of maximum electric field intensity, namely, on the fibrous ends of the pile, which act as needles 13,

this produces a significant amount of ozone.

Negatively electrified large and medium particles of dust and other contaminants enter the cylindrical filter housing 1, where under the influence of Coulomb electrostatic and energy forces arising when the C-shaped plate flows around with air,

to it, and the passage through the separation windows 15, are deposited on the bottom 3. Small dust particles, on which the electrostatic charge obtained in the nozzle 2 and the energy of the energy in the housing 1 did not have a sufficient effect and did not reflect them to the C-shaped plate, are additionally in contact with the negative electrode 12 and are also attracted by electrostatic Coulomb forces to the positive C-shaped electrode 14, on which the charges are recombined and dust accumulates on the bottom 3. In addition, the air in the cylindrical case 2 is intensely ionized negative ions that flow from the fibrous ends of the pile, which act as needles 13, thus forming an additional

significant amount of ozone.

The purified and ionized air with the addition of ozone enters through the filter element 9 into the engine intake duct. At the same time, extremely fine dust particles are retained on the filter element 9, which constitute an insignificant percentage of the total number of contaminants, which increases the service life of the filter element before it is replaced.

The dust accumulated on the bottom 3 and other contaminants are removed as follows: unscrew the nut 8 and rotate the cover 6 around the axis until the perforated windows 22 are aligned with the windows 23 located in the bottom 3, remove the contaminants mechanically through the formed channels or compressed air.
