Description
Technical field
The utility model relates to smoke evacuation system, is specifically related to a kind of thermal insulation layer pressurization Anti-corrosive chimney.
Background technology
After wet de-method desulfurization, smoke moisture increases, and temperature reduces, and the liner of chimney easily causes corrosion, and gap, hole that even part wet flue gas is lining with in passing through enter thermal insulation layer, cause urceolus to corrode or seepage, thus affect the service life of chimney.At present, the etching problem of chimney mainly improves from build process and inner lining material aspect, but, no matter be optimize liner build process, still use densification instead, the inner lining material of antiseepage is all difficult to wet flue gas completely isolated, fundamentally can not solve the problem of chimney urceolus corrosion leakage.
Utility model content
Technical problem to be solved in the utility model is, overcomes the deficiency of above-mentioned background technology, provides the thermal insulation layer pressurization Anti-corrosive chimney of the leakage of a kind of anti-corrosion leak-proof, long service life.
The technical scheme that the utility model solves the employing of its technical problem is, a kind of thermal insulation layer pressurization Anti-corrosive chimney, comprise urceolus, the vertical direction of described outer tube inner surface is provided with bracket, urceolus is divided into multiple elementary section by each bracket of vertical direction, the inner surface of each elementary section of described urceolus is provided with liner, thermal insulation layer is equipped with between described urceolus and each liner, be communicated with by the first communicating pipe or punching between adjacent thermal insulation layer, also be provided with air-supply voltage supply equipment, described air-supply voltage supply equipment is by being communicated with thermal insulation layer bottom the second communicating pipe, air-supply voltage supply equipment is to insufflation gas in thermal insulation layer, pressure in described thermal insulation layer is P1, it is flue gas inside described liner, the maximum pressure of flue gas is P2, P1 >=P2.
Further, pressure P 1=1.1 ~ 1.5 P2 in described thermal insulation layer.
Further, the thickness of described thermal insulation layer is 5 ~ 10cm.
Further, described air-supply voltage supply equipment is fan with low voltage.
Further, described gas is air.
Further, described urceolus is armored concrete urceolus.
Compared with prior art, advantage of the present utility model is as follows:
By improving thermal insulation layer space pressure; make the pressure in thermal insulation layer be more than or equal to chimney inside smoke pressure, the flue gas of chimney inside inverse pressure cannot enter into thermal insulation layer, thus becomes protection to outer cylindrical; reach the object that urceolus anti-corrosion leak-proof leaks, improve the service life of chimney.
