On the outer tube wall of described multitube steel chimney 1 flue interface 3 is set, the center line of the center line of described flue interface 3 and steel chimney 1 is 20 °～60 ° acute angles (preferred 30 °～60 ° acute angles), thereby avoids flue gas to flow into the steel chimney 1 of flue interface 3 belows.
As shown in Figure 8, the opening reinforcement of described each flue interface 3 is adopted steel chimney 1 and flue interface 3 to increase steel chimney wall thickness and is strengthened structure 13 and flue interface wall thickness reinforcement structure 31; Increase steel chimney liner plate 14 and flue interface liner plate 32, floor 33, ring flat-plate 34, cover tube 35 reinforcements at the steel chimney 1 and flue interface 3 outsides.In another specific embodiment, support inboard the increasing of steel chimney 1 and flue interface 3 that (water conservancy diversion) dividing plates 36 are strengthened and inboard setting of steel chimney cut off fagging 37 reinforcements.
From absorbing wet flue gas that the cat head central row goes out from bottom to top, the chimney that enters clean internal diameter 2.0m at the 25.2m place connects flue. chimney connect flue interface vertically upward after, become 25 ° of angles to be inclined upwardly with multi flue chimney center vertical line and penetrate steel cylinder, 30.4m locate to intersect with the steel cylinder center line, join fully to 31.4m and steel cylinder through reducer pipe again, row is to atmosphere after rising to 80m along steel cylinder at last. and the acid solution that the discharging wet flue gas forms in steel cylinder is back to the absorption tower along connecting flue. and chimney inside need not be provided with liquid collecting funnel and drainage system.
In another specific embodiment, the metal fluorocarbon coating cover that described steel cylinder 1 can also adopt galvanizing by dipping to spray weather-proof UV resistant again gives anticorrosion (not shown).Adopt the inwall of each steel chimney of the present utility model to be coated with earlier from the chimney flue interface of 25.2m to 31.4m and in the steel cylinder of 31.4m to 80m with controlled surface morphology coating, use grease proofing shock resistance again, ageing-resistant, there is not corrosion, anti-deep cooling and high temperature, it is low that the acidproof binding agent lining cutting that adhesion strength is high has unit weight, the intensity height, thermal conductivity factor is little, non-hygroscopic, airtight, do not burn, prevent nibbling mothproof, acid-fast alkali-proof, nontoxic, "dead", stable chemical performance, easily processing and indeformable acidproof borosilicate foam glass brick spray high strength at the foam glass brick inner surface at last again, low-friction coefficient, acid and alkali-resistance, ageing-resistant, high temperature resistant, the investment precoat that adhesive strength is high.Acidproof foam glass brick can effectively solve anticorrosion, the heat-insulating problem of steel chimney.It can make steel chimney wall and ambient temperature differences be controlled in 25 ℃.Acidproof bonding agent lining cutting 42～50mm (steel cylinder 42mm of 20mm wall thickness, the steel cylinder 46mm of 16mm wall thickness, the steel cylinder 50mm of 12mm wall thickness) thick acidproof foam glass brick, foam glass brick surface are coated with the shutoff of controlled surface morphology coating again, and the following steel inner cylinder of flue interface is not established thermal insulation layer.
All quote in this application as a reference at all documents that the utility model is mentioned, just quoted as a reference separately as each piece document.Should be understood that in addition after having read foregoing of the present utility model, those skilled in the art can make various changes or modifications the utility model, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
