Description

The invention relates to the construction, in particular to chimneys for cleaning industrial gases before they are emitted into the atmosphere and is supplementary to the main one according to the author. No. 998821.

The purpose of the invention is to increase the degree of gas purification.

The drawing shows schematically the flue pipe, a longitudinal section.

A dry and a wet cleaning pipe, the lower part 1 of which is made of reinforced concrete, and the upper part 2 (above the sludge collector-) made of stainless steel, contains an inertial cyclone 3 with a bottom ash collector 4, unloading windows 5 and a reinforced concrete floor in the lower part of the gas exhaust trunk 6, filled with a central nozzle 7, 20 drops of moisture flow down an inclined tangential blade above the nozzle 8 onto an inner surface

gas outlet trunk, from where, disruption, cf. droplet formers 15, flue gases entering the pipe. The exhaust fan 9 is installed on the ceiling 6. The sludge collector 10 with the central nozzle 11 is installed at a distance of 25 from the cyclone and forms a room 12c with a door opening 13 with the inner surface of the barrel. A droplet separator 14 is installed in the mouth of the pipe, made of ZO stainless steel sheet ,, Cimosos 9 is connected to nozzles 7 and 11.

Dowa pipe works as follows.

The gas flow sucked in by the smoke exhauster 9 from the nozzle 8 of the tangential inlet through the central nozzle 7 of the inertial cyclone 3 forms a constant vacuum inside the cyclone. The suspended parts of the gas, which are withdrawn under the action of centrifugal forces to the walls of the cyclone, are lowered in a rarefied medium down the gas exhausting trunk, settle on the bottom

give the sludge collector.

Flue gas suction from the delicate part of the shlee gas trunk (from the cyclone) and pumping them through the central nozzle of the sludge collector to the upper part of the gas exhaust pipe compensates for the loss of the chimney because of an increase in aerodynamic resistance during wet cleaning, improves condensation mode by pressure differential cold air suction valves, ensures the efficiency of the flue pipe of dry and wet gas cleaning. This construction allows drastically reducing the cost of building a chimney at the expense of an insignificant height of the structure, while ensuring a sufficiently high degree of flue gas cleaning.

the ash collector 4, the flue gases, which are extracted without the cost of special equipment for removing suspended particles, is exhausted by the exhaust fan through the central nozzle 7 of the cyclone 3. The vacuum thus maintained in the cyclone and the degree of dryness

the knowledge. In addition, the installation of an exhauster for an inertial dry cyclone reduces the cost of current repair of parts subject to abrasive wear.

Placing the sludge collector 10 at some distance above the cyclone improves its performance in wet gas cleaning. Education room 12 with doorway 13,
