Description

The utility model relates to the purification of liquid-gas media (GHS) and can be used to isolate dispersed particles from gases, liquids, disinfection of GHS from floating microorganisms using the electrostatic effect.

Known electric cleaner (EO) of gaseous media containing a dielectric housing with an ozonizer-ionizer installed at the inlet and precipitation electrodes, while the internal volume of the housing is divided across at least two parts by a permeable electrically conductive partition, and the direction of movement of the gas stream is contaminated medium perpendicular to the horizontal planes of the surface of the ionizer-ozonizer and the first permeable septum. A potential difference is alternately supplied to the permeable conductive partitions, and the resulting chamber volumes are filled with a dielectric permeable material and together with the permeable conductive partitions function as volumetric precipitation electrodes. The ozonizer ionizer has a potential sign opposite to the potential sign of the first permeable partition. /one/.

The disadvantage of this electric cleaner, adopted as a prototype, is the insufficiently high cleaning efficiency, due to the low deposition rate of pollution particles.

The deposition rate is the most important value used to determine the efficiency of the electric cleaner, increases with the migration rate. The migration rate depends on the charge of pollution particles and on the electric forces acting on them (ponderomotive and Coulomb forces) / 2, 3 /. It is necessary to ensure maximum charge of particles

micro-pollution, and to increase the effectiveness of ponderomotive forces it is necessary to create the maximum heterogeneity of the electrostatic field, which is impossible to do in the prototype.

The technical task of the utility model is to increase the efficiency and quality of cleaning liquid-gas media.

The solution to the technical problem of the utility model is that in a universal filter containing a dielectric housing, precipitation electrodes, while the inner volume of the housing is divided into parts by permeable electrically conductive partitions and filled with a dielectric permeable material, which, together with the electrically conductive partitions, performs the function of volumetric precipitation electrodes, and the direction of movement of the gas flow of the polluted medium perpendicular to the horizontal planes of the permeable electrically conductive partitions, permeable electrically conductive partitions are made without an insulating coating, the potential difference is supplied to them in pairs, for which the internal volume of the housing is divided into at least three parts, the dielectric permeable material filling the space between the electrically conductive partitions can be distributed randomly and orderly.

Comparative analysis with the prototype allows us to conclude that the claimed device has significant distinguishing features and new connections, namely the following elements: permeable conductive walls are made without insulation coating, the potential difference is supplied to them in pairs, for which the internal volume of the housing is divided, at least into three parts, the dielectric permeable material filling the space between the electrically conductive partitions can be distributed both randomly and orderly.

Analysis of the known technical solutions in the study area allows us to conclude that they lack features similar to the significant distinguishing features in the claimed device.

The combination of these distinctive features provides a technical result of the claimed utility model as follows. Improving the quality of cleaning of liquid-propellant liquids by maximizing the charging of particles of microcontaminants by pairwise supplying the potential difference to permeable conductive walls made without an insulating coating and polarization of volumetric precipitation electrodes, which are a dielectric permeable material in the form of fibers, chips, etc., which leads to to electric field distortion. In addition, the GHS flow in this case is realized between the elements of the volumetric precipitation electrode, which causes a mechanical approach of the pollution particles to high-tension zones. The elements of the volumetric precipitation electrode form stagnant zones where pollution particles are held, thus, the principle of holding particles outside the main stream is implemented.

Figure 1 shows a longitudinal section of a universal filter; figure 2 - the results of experimental studies to determine the effectiveness of cleaning the gaseous medium from particles of microcontaminants and the claimed utility model.

A universal filter (Fig. 1) consists of a housing 1, a permeable electrically conductive partition 2, volumetric precipitation electrodes 3 placed in internal volumes, current leads 4. Power from a high voltage source is supplied to the electrically conductive permeable partitions 2 with alternating sign of potential.

The filter works as follows.

Particles of contaminants that are in the ZhGS environment and do not have a charge, passing through the first conductive partition 2, are charged from a high potential supplied from an external high-voltage power source. Passing through the second electrically conductive partition 2, which has the same sign of potential as the first, the particles of microcontaminants maximize their charge and are deposited on the second bulk sedimentation electrode

3. Particles of contaminants that have not settled on the second volumetric precipitating electrode and the first two conductive permeable walls, under the influence of an inhomogeneous electric field, move through the third permeable conductive wall 2, which has the opposite sign of potential with respect to the first two, to the third volumetric electrode and are deposited on him.

Particles of contaminants located in the GHS environment and having a charge opposite to the charge of the first two conductive partitions 2 are deposited on the first and second precipitation electrodes 3.

To determine the effectiveness of cleaning the gaseous medium with the prototype and the claimed utility model, experimental studies have been carried out. Using the aerosol particle counter of the GTA GTA 0.3-002, under equal external conditions, the number of particles of microcontaminants contained in the gas medium was measured with dimensions of 0.3 μm, 0.4 μm, 0.5 μm, 0.6 μm, 0 , 8 μm, 1 μm and 1.5 μm at the inputs of gas purification devices of the prototype and the claimed utility model, as well as at the outputs of the above devices. According to the data presented in Fig. 2a, the efficiency coefficient of purification of the gaseous medium (1) by the prototype and the claimed utility model is determined.
