SU54848A1 - Plate element for plate filters, humidifiers, surface heat exchangers and similar devices - Google Patents

Description

The proposed plate-like element is intended for metal plate filters, humidifiers of various kinds of surface heaters and the like devices made of a number of elements disposed at a certain distance from each other. The plate element is provided with alternating elevations and depressions, which are formed by corrugating sheet rolling in two that do not coincide with each other, for example, mutually perpendicular directions.

In the schematic drawing of FIG. 1-3 depict three different forms of implementation of a filter-radiator of lamellar elements, FIG. 4, 4 is a view in two projections of one of the plate elements; FIG. 5 is a perspective view of this element and FIG. b explains the process of making the item.

Surface heat exchangers, filters, humidifiers and similar devices are prepared from a series of metal plate elements p (Fig. 1), installed in parallel and at some distance from one another. Each element has an uneven surface and is provided with depressions and elevations that can be obtained, for example, by corrugating a metal sheet, first in one diagonal direction (Fig. B), and then perpendicular to it, while retaining the first folds (Fig. . four). This will result in a plate, the shape of which is a sleep from FIG. 5. As a result of cross folds of double corrugation, recesses C are formed on this plate with walls t, and, v, w and their corresponding elevations D (Fig. 4 and 5):

The resulting plate elements are installed in accordance with the purpose of the device, for example, a filter, in the horizontal (Fig. 1) or in the vertical (Fig. 2), or tilted (f | ig. 3), or, finally, in the plane the direction of any curve.

When using a filter solely for the purpose of air purification, elements installed predominantly horizontally are covered with oil or other liquid suitable for absorbing dust. In this case, the depressions C of the elements (Figs. 4 and 5) serve as cells for the O oil filling them (Fig. 1).

With the passage of air between the plate-like elements of the filter, the impurities contained in the air, due to a sudden and continuous change in the direction of airflow from the cross-folds of the elements, settle both on the oil surface of the recess C, as well. and on the oil surface of elevation D.

The impurities precipitating from the air on the surface of the plates form a kind of wick which, impregnated with oil O from the cells (Fig. 1), promotes intensive absorption of impurities from the air passing through the filter.

When using the specified filter, not only for cleaning, but also for heating or cooling and humidifying or draining the air, metal elements installed mainly in a vertical or inclined position are irrigated with water or other liquid of a corresponding temperature. In this case, the plates serve as a filtering and heating or cooling surface, helping at the same time to increase or decrease the humidity of the air passing through these plates. Thus, in this case, the metraltic filter serves as a radiator at the same time.

Placing the plates in a vertical position (Fig. 2) can take place when it is required, simultaneously with heating or cooling the air, to increase the moisture content of this air. In this case, a liquid of the appropriate temperature irrigates the plates in the direction indicated by the arrow /, and washes both sides of the plates, and the air passing through

The opposite direction of the liquid, indicated by the arrow /, is heated or cooled with simultaneous moistening.

The installation of the elements in an inclined position (Fig. 3) is intended for the case when it is necessary to maintain a reduced humidity in it simultaneously with heating or with air cooling. In this case, a liquid of a corresponding temperature, irrigating the plates, washes them on one side, while the other side of the plates serves as a heating or cooling surface. The air going in the opposite liquid direction perceives less moisture due to the fact that one side of the plates is involved in moistening, and both sides of the plates are heated or cooled.

When using a filter-radiator, the metal plates (Fig. 5) are simultaneously installed in a vertical (Fig. 2) or inclined (Fig. 3) position and are irrigated with a liquid of the appropriate temperature for cooling and air draining. In this case, the air, the passage in the opposite direction, is cooled and when cooled below the dew point, moisture is released from it, and, consequently, air is dried.

The subject matter of the invention.

A plate element for plate filters, humidifiers, surface heat exchangers and the like devices, provided with alternating recesses and elevations located at some distance from each other, characterized in that the recesses and elevations of the element are formed by corrugating the plate (sheet) in two coinciding with each other, for example, mutually perpendicular directions.
