Description
Technical field
The utility model relates to a kind of anticorrosive dust-collecting energy-saving chimney.
Background technology
In recent years, be protection of the environment, the flue gas that contains nuisance sulfur dioxide that the industries such as smelting, generating, chemical industry are produced namely carries out wet desulphurization before it enters chimney, thereby the cigarette temperature is dropped to below the dew point; But consequent acid solution is dirty along inner wall of stack, very easily makes liner rot to cause the cylindrical shell cracking.
For addressing this problem, general method is to install inner sleeve in chimney.But such inner sleeve involves great expense.210 meters chimneys of 600,000 kilowatts of thermal power plants for example, the inner sleeve investment needs 1,000 ten thousand yuan unexpectedly, and the flow-disturbing effect is bad, and the also only measure of being convenient to change of this method, is the way of curing the symptoms, not the disease.
The utility model content
Solve the cylindrical shell etching problem and cause cost high by the installing inner sleeve in order to overcome existing chimney, and the deficiency that the flow-disturbing effect is bad, the utility model aims to provide a kind of anticorrosive dust-collecting energy-saving chimney, and this chimney cost is relatively cheap, have anticorrosion, gather dust, energy-conservation function.
To achieve these goals, the technical scheme that adopts of the utility model is:
A kind of anticorrosive dust-collecting energy-saving chimney comprises chimney barrel, and it is 10 ° ~ 90 ° interior thorax helix that the inwall of described chimney barrel is provided with lead angle; The outlet that is positioned at the arc flue of chimney barrel lower end outside is communicated with described thorax helix, the hook direction of described arc flue and the hand of spiral of interior thorax helix in the same way and described arc flue and interior thorax helix be smooth connection; Its design feature is, described interior thorax helix is many, the interior thorax helix radical in chimney barrel varying level cross section equates, and every interior thorax helix is along with the increase of chimney barrel level height, and the interior thorax helix of the position that level height is high is by the chimney barrel inwall height H outstanding to the chimney barrel center
hThe interior thorax helix of the position that≤level height is low is by the chimney barrel inwall height H outstanding to the chimney barrel center
L
In the utility model, the chimney barrel center of certain level height position refers to the center of circle of this At The Height chimney barrel horizontal section.
As a kind of specific embodiment, the chimney barrel equal diameters in described chimney barrel varying level cross section, and the interior thorax helix of the high position of level height is by the chimney barrel inwall height H outstanding to the chimney barrel center
hThe interior thorax helix of the position that=level height is low is by the chimney barrel inwall height H outstanding to the chimney barrel center
