Description

MULTI-SMOKED SMOKE PIPE

The utility model relates to a power system and can be used in the construction or reconstruction of multi-barrel chimneys containing a reinforced concrete shell and gas outlet pipes protruding from it, the annulus between which is covered by a roof.

A multi-barrel chimney 1 is known, containing a reinforced concrete shell with gas outlet trunks protruding from it, the annular space of which is covered by a roof on its slice, the protruding part of the trunks is enclosed in a casing with overlap, and the trunks pass through the overlap and the roof with gaps communicating the annular space with the atmosphere. In the known pipe, the installation of the casing allows you to protect the protruding part of the trunks from destruction as a result of self-enveloping flue gases.

A disadvantage of the known multi-barrel chimney is that it does not eliminate the phenomenon of self-enveloping of the casing and reinforced concrete shell with aggressive flue gases.

The technical result of the utility model is achieved by the fact that in a multi-barrel chimney containing a reinforced concrete shell with gas outlet trunks protruding from it, the annulus of which at its section is covered by a roof, the protruding part of the trunks is enclosed in a casing with overlap, and the trunks pass through the overlap and the roof with gaps communicating the annular space with the atmosphere, the casing is made in the form of a confuser, the latter in the lower part has the shape of a circle, and in the upper part is made in the form of a wavy converger, herpes The exhaust gas trunks of their perimeter.

The essence of the utility model is illustrated in FIG. 1 and FIG. 2, section 1-1 in FIG. The multi-barrel chimney contains a reinforced concrete shell 1 and gas discharge trunks protruding above it 2, the annular space 3 between which in the upper part is covered by a roof 4, and the protruding part of the trunks 2 is enclosed in a casing 5 with an overlap 6, and the casing 5 is made in the form of a confuser, resting on bearing trunk 1. Gas exhaust trunks 2 pass through the roof 4 and the casing 5 with annular gaps 7. The casing 5 in the lower part is made in the form of a circle, and in the upper part in the form of a wavy confuser encircling the gas exhaust trunks 2 along their imetru.

The proposed multi-barrel chimney works as follows. The flue gases pass through the internal channel of the exhaust trunks 2 and are discharged out into the atmosphere. Air from the annulus 3 passes through the annular gaps 7 and enters the leeward region of the bearing trunks, which increases the air pressure in this region and reduces the suction of flue gases from the root region of the smoke plume. The lateral drift wind flow from the front side smoothly flows around the confuser casing and closes the annular gap between the trunks, thus increasing the rate of air exit from the annulus to the leeward side of the casing, which contributes to an increase in pressure and a decrease in the flow of exhaust gases. At the same time, the enveloping of the reinforced concrete shell is also reduced. The execution of the casing in the form of a wave-like confuser contributes to an increase in air pressure from the leeward side, which reduces the self-enveloping of the latter.

Thus, the proposed utility model allows to reduce the self-enveloping of the tip of the multi-barrel chimney and increase the reliability of its operation. Head of Patent Information Department // Yablokov V.P.
