Description

There are well-known dMyogograna and, including, tetrahedral deflectors with diagonally arranged partitions connecting the upper and lower sides of the deflector faces with each other, deflecting air jets in the vertical direction, and with a number of vertical partitions perpendicular to the edges of the faces, moreover, alive the cross section of the areas of the entrances to the passages between the upper and lower edges is less than the living cross section of the outlets from these canals into the central bore duct, above which the dorsciformis cap is mounted; spruce.

In such four-sided deflectors with brown partitions perpendicular to the edges of the vertical partitions, the partitions are given an outline along curvilinear smooth generators.

From the known deflectors of this type, the proposed deflector is distinguished by the fact that, with the aim of arranging dead zones in the areas adjacent to the diagonal partitions with air streams of different directions, the vertical partitions are perpendicular to the edges of the edges.

along the length and not reaching before the meeting with diagonal partitions and edges of the faces of the exhaust duct.

This deflector is also applicable for installation on the chimney as a bell-exhaust fan.

In FIG. 1 shows a general view of the deflector; FIG. 2 - its vertical section; FIG. 3 is a plan view of its lower part; FIG. 4 shows an embodiment of a deflector in the form of a diusap cap mounted on a chimney; FIG. 5 - longitudinal vertical th section; FIG. 6 is a plan of the blubber part of the deflector in the form of the embodiment of FIG. 4 and 5.

The deflector shown in FIG. 1, 2 and 3, consists of two rows of curved brown partitions C and D, four in each row, are located on the four faces of the exhaust tube A and connected between themselves by diagonal vertical partitions 3, on the upper releases of which attached two copiramidal cap-reflector E.

The diagonal partitions 3 divide the body of the deflector into four passage channels, in which they are set perpendicular to the facets of the exhaust pipe A of the partition B, gradually increasing to the middle of the 1-square, but not reaching before the diagonal partition and front of pipe A.

In the direction of the wind perpendicular pH: about 1 grams, which is relatively rare, these partitions B do not have an “excellent action,” since air flows directly from the inlet to the outlet D under the hood E above the exhaust pipe. The projection of a jet of air in this direction or 1 when diagonally blowing these partitions staiovat with reflective elements, translating the jet of Air in a direction perpendicular to the face, t. creating the most advantageous deflector effect; square in terms of shape, this gives 1nw most coverage of a working wind jet.

Blowing into the exhaust canal occurs, by the glacier 0: braz. 1, because the web is usually at an angle of about 10 ° to the horizon, as a result of which it has direct access to, and: the red partitions C and D, which have a crookedly perforated o drawing, from the air stream from its direction, transfer it almost vertically over the exit from the exhaust duct of the duct hole D for the double pyramidal cap E, where this jet does not receive a backward reflection in the duct, as with simple caps, but reflection aside - na exit.

If: a stream of air is imagined to be broken and vertical to the elements, then each lower element, receiving a reflection from the blond partition B upwards, meets with a subsequent element, which again presses it to this partition, as a result of which the jet is supplied to the outlet port D Since the living cross section of the inlets of the passages I exceeds several times the live cross section of the outlets, the speed of the air jet in the latter increases by the same amount, creating even with weak wind a strong suction of gases from the exhaust pipe A. Be The curvilinear P0 (the surfaces of the partitions G give the same slip of the air jet along them, bringing it also under the reflector cap E.

The described device of the deflector is applicable to dy.m. pipes as a smoke exhauster. For this, the upper surfaces B of the chimney along its perimeter are attached to a curve-linear shape (Figs. 4 and 5), deflecting the air jet vertically; in the corners of the pipe are reaching the chimneys: A diagonal 3, and perpendicular perpendicular to the sides of the pipe partitions B, o: tlopyuschie wind jets in the direction of the smoke, and the latter closest to the diagonal walls 3 are not all pipe wall width; the entire space occupied by the partitions B is re-ripped by the hip cover D, which leaves its own passageway through the chimneys A; this cover, having a slope of slopes of about 10, equal to the slope of the wind jet, leads it to a horizontal direction towards the jet coming from chimneys A from below; On the upper sections of the angular partitions 3 and partially on the intermediate ones there is a double pyramidal reflector cap E.

PRE M E of the Invention.

Multifaceted, for example, a tetrahedral deflector with vertical partitions located both diagonally and perpendicularly to the 1C edges of the lateral faces and connecting the upper and lower edges of the sides of the deflector, deflecting the air jets towards the central an extended cajala overlapped by a duplicating cap-reflector, which is the fact that, in order to eliminate the formation of dead zones in the adjoining areas: diagonal partitions at air flows The horizontal partitions are perpendicular to the edges of the faces, the vertical partitions are made shorter in length and not reaching before the meeting with the diagonal partitions and with the edges of the faces of the exhaust channel.
