The goal is to simplify the design and increase the efficiency of the filter. The filter includes a housing, an elastic element on which a filtering element is installed, limited from the ends by end caps made of electrically insulating material, the upper of which is equipped with a vibrator actuator, made in the form of a disk with a hemispherical depression and a central hole, and the bottom is made in the form of a ring, matching with a hollow truncated reverse cone, the smaller base of which is connected to the central perforated tube of the filter element. The filter element is limited by a perforated shell and has electrodes made in the form of plates, one of which is made of the same polarity and is connected to the shell, the others alternating with them are made of the other polarity and are connected to the central perforated tube. The upper surface of the vibroactivator disk is located in the same plane with the output end of the inlet pipe of the cleaned fluid, the outer diameter of which is equal to the diameter of the depression of the vibroactivator disk, and the outlet pipe is installed axially in the inlet pipe of the cleaned fluid, while the lower end of the outlet pipe is located in the central hole of the vibroactivator. 2 Il.

Description

one

The invention relates to the purification of liquids from suspended particles and can be applied for the purification of petroleum products and water from contaminants.

The purpose of the invention is to simplify the design and increase the efficiency of the filter.

FIG. 1 shows the filter, general view, section; in fig. 2 shows section A-A in FIG. I.

The filter includes a housing 1 with a lid 2, an elastic element 3 on which the filtering element 4 is installed with a bottom end lid 5 made in the form of a ring coupled to a hollow truncated reverse cone, the smaller base of which is connected to the central tube 6 of the filtering element 4. On the upper end cover 7 of the filter element 4 is installed vibroactivator 8, made in the form of a disk with a hemispherical cavity 9 and a Central hole 10. The upper surface 11 of the disk is located in the same plane with the output end 12 of the Pat the sink 13 supplying the cleaned fluid, and the outer diameter of the nozzle 13 is equal to the diameter of the cavity 9 of the vibroactivator disk 8. The outlet 14 is installed along the axis of the inlet 13 and the lower end of the outlet 14 is placed in the central opening 10 of the vibroactivator 8. The filter element has a perforated outer shell ib and multi-band electrodes 16 and 17, made in the form of plates, radially and alternately mounted on the central tube 6 of the same polarity and on the outer

with

the shell 15 of a different polarity, the electrodes are connected to a source of constant electrical voltage, the end covers 5 and 7 of the filter element 4 are made of an electrically insulating material. The housing 1 in the lower part has a sludge drainage pipe 18.

The filter works as follows.

The fluid supplied to the cleaning enters the housing 1 through the nozzle 13, due to the velocity head the filter element is displaced downwards, thereby deforming the elastic element 3. The value of the annular gap between the end of the nozzle 13 and the vibroactivator 8 is not constant, it is turbulent, and the frequency of the oscillatory process is determined by the rigidity of the elastic element 3.

Under the action of an electrostatic field between the plates 16 and 17, suspended particles from the flow of passing fluid move toward the plates and due to their vibration are dropped into the conical cavity of the bottom end cover 5, where the slits enter the bottom of the housing 1 and as they accumulate are removed from the filter housing through pipe 18 (shut-off valves are not shown).

The application of the above construction allows the movement of the purified liquid inside the filter cavity at a sufficiently low speed, which makes the electrophoretic deposition of suspended particles high efficiency towards the plates, their further coagulation, and the vibration of the filter element facilitates the movement of the coagulated particles along the plates. towards the dirt chamber without any constructive obstacles. The design increases the cleaning efficiency with its sufficient simplicity.
