Abstract

A multi-barrel chimney containing a reinforced concrete shell with gas exhaust trunks, the annular space of which is covered by a roof, characterized in that the trunks above the roof are enclosed in casings with the formation of a gap communicating the annular space with the atmosphere, and rely on the roof, and the casings are connected to a section of the trunks of the trunks a plate made of corrosion-resistant material.

Description

Multi-barrel chimney

A useful model for Olshoshitoy to heat power systems can be used in the construction and reconstruction of multi-barrel chimneys, DISCHARGE 1 / 1X flue gases from boilers of power units.

The multi-barrel chimney / I / is widely known, containing a reinforced concrete shell, inside of which several gas exhaust trunks are installed with the formation of the annular space. The annulus at the mouth of the pipe is covered by a roof resting on the head of the reinforced concrete shell. Exhaust trunks rise above the roof. Air from the annulus is removed through windows made in the head of the reinforced concrete shell.

The disadvantage of the well-known multi-barrel chimney is that when the exhaust gases exit the exhaust trunks, the outer surface of their heads is wrapped above the roof under the influence of a blowing side wind. During the shutdown of some trunks, their heads are exposed to flue gases from working trunks. As a result of enveloping the heads, the aggressive constituent of the exhaust gases, condensing, destroy the heads of the trunks during operation.

The technical result of the utility model is aimed at improving the reliability of the multi-barrel chimney by a shower eliminating the influence of self-enveloping the ends of the trunks and the effect of aggressive co-flue gases on them.

The technical result is achieved by the fact that in a multi-barrel chimney containing a reinforced concrete shell with a gas outlet / 1 # 1 trunks, the annular space of which is covered by a roof, the ends of the trunks above the roof are boiled in a casing with

the formation of a gap that informs the annular passage about the atmosphere, and os / 1 rash1111 on the roof, moreover, at the end of the heads oj BOJioB Koityxa are tied with a plate made of corrosion-resistant material,

The conclusion of the ends of the bends in the formed gap, which communicates the annular prototranotvo with the atmosphere, and which are supported by the roof, allows for an organized exit of air from the annulus and create an air curtain on the section of the ends of the trunks, preventing their contact with aggressive outgassing gases.

The installation of a plate of corrosion-resistant material on a section of the heads of the trunks connecting the: kitchen to each other, eliminates the wrapping of all the heads in the center of the pipe above the roof, which prevents their destruction under the influence of aggressive components of the flue gases.

The essence of the utility model is illustrated by the drawing, which shows the proposed multi-barrel chimney. In FIG. I. presents a section aa in Fig.2., Fig.2. view B in figure 1.

The proposed multi-barrel chimney contains a reinforced concrete shell I with gas exhaust trunks 2, the annulus 3 of which is covered by a roof 4. Each end of the gas exhaust trunks 2 is snarled in 5 to form a gap 6, which communicates the annular space 3 with the atmosphere.

On the section of the heads of the trunks 2, a plate 7 of a corrosive material is connected, connecting 5 to each other.

The proposed chimney works as follows. The flue gases from the boilers pass through the exhaust pipes 2 and are discharged into the atmosphere. Air from the annular space 3 passes through the gap 6 between the spools 5 and the heads of the exhaust trunks 2, creating a curtain on their outer side, which forces the exhaust gases away from the aggressor. When some trunks are stopped in reserve, from the usual space 3, leaving the bunk} through the gap 6, prevents the aggression of 1/1 of the exhaust gas from flowing into the idle exhaust trunks from the workers, which reduces their corrosion damage.

The presence of a plate 7 made of corrosive material at the section of the ends of the trunks 2, connecting the casing 5 1 / 1e} to each other, prevents the wrapping of the ends of the trunks in the center of the pipe, while the space is blown away by the wind stream 8, which removes the aggressive components of the exhaust gases from the roof and the stove center of the pipe. The implementation of PLGGG 7 of a corrosion-resistant material increases the durability of the structure.

Thus, the proposed utility model makes it possible to increase the reliability of ij, the uni-durability of the multi-barrel chimney in the conditions of variable operating modes of the connected units.
