UA39739U - Electrostatic filter for dispersed phase - Google Patents

Abstract

An electrostatic filter for dispersed phase relates to the methods of removal of dispersed phase from gases and can be used in heat-power engineering, metallurgical and chemical industry, in the production of building materials, in machine building and other branches of industrial production.

Description

The electrostatic filter for the dispersed phase contains a straight, vertical channel 1 with plane-parallel side walls 2, which are formed by deposition electrodes of a truncated M/- profile, the planes of which in the horizontal direction form sequentially installed vertical troughs 3 with sources of electrostatic - corona placed between them in the form of dots discharge 4. In each channel 1, the opposite walls 2 of cut M/-profiles in the vertical direction form truncated straight prisms 5 of equal height and volume, which are spaced at a distance Pp, which is equal to the distance between the sources in the form of points of the corona discharge 4.

At that time, in the horizontal direction, they are separated by a distance of H and the truncated vertices are oppositely turned, while ensuring, in the horizontal direction, on the one hand, the collision of the opposite flat vertices 6 of the truncated prisms 5 with spherical equipotentials 7 of radius K, the centers of which are located at the locations of the sources in the form of corona discharge points 4 and located in the axial plane of the channel 1. In addition, the collision of opposite neutral lines of force with the same spherical equipotentials 7 is ensured, while the position of the points of contact of the spherical equipotentials 7 with the flat tops 6 of the truncated prisms 5 coincides with the direction of the central of the line of force of the electric field from sources of corona discharge 4. The height difference of Uy-profile a is no more than 0.1-0.22. The mechanical interconnections of the walls 2 of the cut M/-profiles are bent elements 8, which create vertical stiffening ribs of the gutters 3, the height of which is comparable to the height difference of the Mu-profile and is no more than 25 -02-045.

Such an electrostatic filter device for the dispersed phase provides an increase in the efficiency of capturing the dispersed phase by increasing the mechanical rigidity and shaking efficiency of the non-coronating electrode, using transverse vertical ribs that increase the resistance moment indicator, while minimizing secondary carryover by creating sufficiently deep vertically located pockets, taking into account the increase height difference of the wave-like (M/) profile, as well as excluding turbulent disturbances arising from the surfaces of the (M/) profile when the gas flow flows around it, in particular when it flows around the transverse vertical ribs, which in general contributes to reducing the degree of secondary drift and increasing the efficiency catching

The device works like this.

The electrostatic filter for the dispersed phase contains a rectilinear, vertical channel 1 with plane-parallel side walls 2, which are formed by deposition electrodes of a cut M/- profile, the planes of which in the horizontal direction form successively installed vertical troughs C with sources of electrostatic - corona placed between them in the form of dots discharge 4. In each channel 1, the opposite walls 2 of cut M/-profiles in the vertical direction form truncated straight prisms 5 of equal height and volume, which are spaced at a distance Pp, which is equal to the distance between the sources in the form of points of the corona discharge 4.

At that time, in the horizontal direction, they are separated by a distance of H and the truncated vertices are oppositely turned, while ensuring, in the horizontal direction, on the one hand, the collision of the opposite flat vertices 6 of the truncated prisms 5 with spherical equipotentials 7 of radius K, the centers of which are located at the locations of the sources in the form of corona discharge points 4 and located in the axial plane of the channel 1. In addition, the collision of opposite neutral lines of force with the same spherical equipotentials 7 is ensured, while the position of the points of contact of the spherical equipotentials 7 with the flat tops 6 of the truncated prisms 5 coincides with the direction of the central of the line of force of the electric field from sources of corona discharge 4. The height difference M/- profile a is no more than 0.1-0.22. The mechanical interconnections of the walls 2 of the cut M/-profiles are served by bent elements 8, which create vertical stiffening ribs of the gutters 3, the height of which is comparable to the height difference of the M/- profile and is no more than 25 -02-045.

When high voltage direct current is applied to the sources in the form of points of electrostatic - corona discharge 4, relative to non-coronating, vertical troughs of the MuU-profile, a sharply inhomogeneous, unipolar, electrostatic field is formed. After feeding, in the direction from the inlet to the outlet of the process gas containing the dispersed phase, its capture is carried out under the conditions of increasing the efficiency of capturing the dispersed phase due to the possibility of increasing the mechanical rigidity and shaking efficiency of the non-coronating electrode due to the use of transverse vertical ribs 8, which increase the index of the moment of resistance , while minimizing the secondary drift by creating sufficiently deep vertically located pockets, taking into account the increase in the height difference of the wave-like (MU) profile, as well as excluding turbulent excitations arising from the surfaces of the (MU) profile when the gas flow flows around it, including when flowing around the transverse vertical ribs 8, which in general helps to reduce the degree of secondary drift and increase the efficiency of capture. 1.
