Description

holes and provides with scaly protrusion-shaped protrusions placed on the inner and outer surfaces of the plates above the holes from the edges of the protrusions of one horizontal row facing towards the flow, and the edges of the adjacent row along the stream,

FIG. 1 shows schematically a fog coagulant, a view to the glider in FIG. 2, view A in FIG. one; in fig. 3 section bb in fig. 2} in FIG. 4 - plate surface element, axonometric,

The foggy coagulant of a mist includes a series of parallel-plates 1 arranged at a certain angle to the direction of the air flow, containing a suspended liquid dispersed phase (mist).

The inner 2 and outer 3 surfaces of the adjacent nhacTHH form separating channels 4. On the inner surfaces of the plates 1 are placed with an interval of a row of scaly protrusion-shaped protrusions 5. The front bending edge 6 of the protrusions 5 are directed towards the air flow; under the protrusions 5 in the body of the plates 1 are placed oblong holes 7. The holes 7 along the length of the plates are placed with a certain pitch. Between the rows of protrusions 5 on the outer side 3 of the plates 1 protrusions 8 are arranged, the bent edges 9 of which are directed along the air flow. Under the protrusions 8, there are holes 10, and the holes 7 and 10 are arranged in rows relative to each other in a checkerboard pattern.

Lamellar coagulum fog works as follows.

The air stream containing suspended particles of liquid aerosol () flows to the entrance edges of the plates 1. And, breaking up into narrow streams, passes through the separation channels 4. At the same time, large particles of aerosol are pressed to the inner surfaces 2 of the plates 1 and are deposited on them. The protrusions 5 contribute to the creation of increased turbulence in the flow in the wall layer and, accordingly, intensify the process of aerosol deposition. The protrusions 8 on the outer sides of the 3 plates also contribute to the creation of a turbulent surface layer. Simultaneously happening

the flow of air through the holes 7 and 10 into adjacent channels 4. This contributes to the additional curvature of current lines, the creation of developed turbulence over the entire width of channels 4 and the intensification of the deposition and coagulation of fine aerosol particles that do not have sufficient inertia and follow current lines. At the same time, the flow of air through the openings 7 and 10 prevents the formation of deposits on the surface of the plates 1 and allows the channels 4 to be made with a sufficiently large width, which leads to a decrease in the hydraulic resistance.

The proposed coagulator is simple in design, reliable in operation, and can be used as a 1st (inertial) stage in front of fiber filters used as oil separators in various sectors of the industry.
