Description

one

The invention may be used in the elements of the arrhythmia cyclone, i.e., in mass-exchange automata.

A cyclone element is known, which includes a housing with a twisting device mounted at the inlet, and an exhaust pipe forming an annular gap with the housing wall.

A disadvantage of the known cyclone element is the low cleaning efficiency.

In the proposed cyclone element, the entrance section of the exhaust pipe is made toothed with a profile of teeth in the form of triangles whose height is 1-2d of the exhaust pipe, and their number is equal to the ratio of the inner perimeter of the latter to the width of the annular gap. This allows for increased dust collection efficiency. In addition, the sides of a triangle may be curved, for example in the shape of an ellipse.

FIG. 1 shows the described cyclone element; in fig. 2 is the same, node I in FIG. 1 (in expanded form).

The cyclopne element includes a housing 1, coaxially with which an exhaust pipe 2 is installed. In the Bodnolg section 3 with an edge 4 there are notches 5 in the form of triangles, and the bases 6 of the triangles 7 are an edge,

and their vertices 8 are located directly by 10 nodes with a twisting device.

The number of notches 6 is approximately the same as the posterior perimeter of the exhaust

pipe 2 (i.e., the length of its circumference along the edge -I) to the syringe of the annular gap 9, therefore the size of the base Hx is close to the size of the gap. The ascending line of the cutouts is given an elongated shape (at least

internal ones).

The height and cut-out is chosen depending on the nominal diameter D of the element in the range of about 1-2 diameters d of the exhaust pipe 2.

The cyclone element works as follows.

Dust gas is attached to the dust by means of a twisting device. In this case, the bulk of the dust is thrown to the inner peripheral wall of the cornea 1. Part of the dust (especially fine fractions and light weight) remains suspended. Depending on the velocity of the gas entering the exhaust pipe 2, the amount of dust carried with the gas into the atmosphere fluctuates as the gas velocity decreases in the device, as the gas passes not only through the lower opening of the exhaust pipe, but also through the cutouts 5 in connection with with approximately HocTOHHiioii performance e.te3

manta gas. The uniform location of the cutouts on the periphery of the exhaust pipe, as well as the smooth increase in the width of the holes from top to bottom, promotes the suction of a minimum of dust, i.e., the harmful effect of disturbances in the organizational-swirling gas flow is minimized due to the gradual change in 1p of the volume of sucked gas when it is from top to bottom.

The described change in the lower part of the exhaust pipe provides the total area of the holes through which the waste gas from the element is removed, 2-3 times larger than in the known elements. At the same time, respectively, the rate of departure of I1, of its gas decreases by a factor of 2–3, and the dust removal of a sokrash is reduced by a factor of 3–4. The efficiency of the battery cyclone increases by 2 times, and the degree of purification increases from 85 to 92-93% for highly polluted gases.

Thus, the cyclone element makes it possible to reduce the dust content of the gas discharged into the atmosphere, and to increase the mezhremolygny service life of rotors and exhausters. The total estimated economic effect on the sintering machine is approximately 20-30 thousand rubles. in year. In connection with the reduction

The gas velocity at the inlet to the exhaust pipe increases the stability of the device operation at capacity jumps — gas (which often takes place due to different resistance of the layer of sintered ichts on aggloles), especially when the jump occurs in a larger direction.
