Description
Technical field:
It is especially a kind of the present invention relates to matching used reinforced concrete chimney in a kind of industry or power generation, drying equipment
The chimney and its method of construction built by fabricated construction.
Background technique:
Chimney be the ventilation of a kind of boiler hot flue gas or smog structure and a kind of exclusion tool, for excluding to be caused by fire
Gas or flue dust.It is a kind of tall and slender structure for flue gas being discharged into high-altitude.Burning condition can be improved, mitigate dirt of the flue gas to environment
Dye.Chimney is usually vertical, or as close possible to vertical, and to ensure gas smooth flow, sucking air enters so-called cigarette
Chimney burning or stack effect.Space in chimney is referred to as flue.
The height of chimney influences its ability that flue gas is transported to external environment by stack effect.In addition, in Gao Hai
Area of rising sheer from level ground using the pollutant diffusion of chimney can reduce influence to ambient enviroment.In the case where chemical corrosivity output,
Sufficiently high chimney can permit the chemical substance in air before reaching ground level partially or completely in self and.Pollutant
Dispersion in more large area can reduce its concentration and promote to meet regulation limitation.
The construction of traditional chimney is to tamp well cabinet frame and the levelling of the land of outrigger region first, and then well cabinet frame basis is poured
Concrete, poppet plate built build chimney shaft, refractory brick, and successively translation frame is built upwards, and internal layer masonry and masonry of outer layer are built
Perlite is filled in centre after to certain altitude, establishes connecting band between ectonexine every certain altitude.Either synovial membrane or
Over-form construction.
Traditional chimney undoubtedly needs bottom that corresponding hardening strength is fully achieved, and can just be built up wall, daily
For construction virtuality generally at 3 meters hereinafter, the wall formed in building course if it does not meet the requirements, can not also be corrected, belonging to can not
It tears open, it can not replacing structure.
