In above-described embodiment, the rigid mount PVC bearing rib 5b adopting in rigid support device 5 is identical with the structure of the flexible carrier PVC bearing rib 6b adopting in flexible supporting device 6, all adopted flange plate type structure, in the material weight that guarantees can reduce under structural strength prerequisite bracing or strutting arrangement, described flexible carrier PVC backing plate 6a, rigid mount PVC backing plate 5a are fixedly connected with nonmetal cylindrical shell 9 outer walls by hot gas welding respectively.
While adopting two chimney, as shown in figure 12, need altogether to install four root posts 3 to be set and to form two equilateral triangles, in each equilateral triangle, connecting cross beam 4, support secondary beam 8 and identical with above-mentioned single chimney by the syndeton of the nonmetal cylindrical shell that more than two sections and two sections nonmetal cylindrical shell 9 connects and composes, do not repeat them here.
Apply the nonmetal chimney stack technical scheme of above-mentioned thermal power plant frame type and possess following technical characterstic and beneficial effect:
1) nonmetal chimney is lightly durable, and chimney body adopts the nonmetals such as PVC that density is little, material is light, and chimney body load is little.After the form that employing segmental structure and rigidity, flexible support combine, the load of every section of cylindrical shell is less, and load is on average born by corresponding each layer of brace summer, total load is born by the basis that is delivered to ground, load distributing homogeneity is good, without too many steel, it is supported, and structural stability is high; PVC sheet material corrosion resistance is strong simultaneously, and without doing preservative treatment, outer lining glass fiber reinforced plastic has very high strength and stability after strengthening, and can be competent at the sour wet flue gas medium that contains after power plant units desulfurization completely, can guarantee in unit long-term safety, stable operation.
1) simple in structure, convenient for installation and maintenance
Because nonmetal chimney body quality is little, and be again segmental structure, between chimney barrel and brace summer, between each section of cylindrical shell of chimney, all adopt the connected mode of bolt fastener, during construction, can carry out easily sectional, when certain section of chimney barrel need to overhaul, remove the support secondary beam of corresponding cylindrical shell, can simply this section of cylindrical shell be pulled down, then in the equilateral triangle space for maintenance moving closer to, as Fig. 2, shown in Figure 12, by adjacent connecting cross beam 4 and the support secondary beam 8 that connects these two connecting cross beams 4, formed, thereby realize chimney barrel section is carried out to independent field-strip, and do not affect the overall structure of chimney and support frame thereof, every section of cylindrical shell can move separately, dismantle, and needn't enter chimney barrel inside, and easy access is safeguarded, can installation and measuring hole and visor on every section of cylindrical shell, be convenient to power plant emission flue gas to carry out environment monitoring.On supporting steel frame, stair and elevator can be installed, also be convenient to carry out Daily Round Check.
2) save and take up an area, connection and reasonable arrangement
The utility model is installed three or the support of four root posts, can arrange single and two stacks body, can meet the needs of current coal steam-electric plant smoke discharge completely, three or four bases only need be done in ground, floor space is little, equilateral triangle area of space between connecting cross beam and support secondary beam can be used as the space for maintenance of nonmetal chimney barrel, also can arrange platform, stair, between the space on basis, ground, can also arrange other equipment and construction of structures, improve the utilization rate in space, power plant place, for the limited old repowering project in place, there is higher layout advantage.
3) duration is short, construction cost is low, good economy performance
Nonmetal chimney body adopts the light and handy PVC plate of material, and chimney body load is little, and support steel structure material usage is few, with concrete chimney, compares, cheap.Adopt steel work as braced structures, compare traditional concrete chimney braced structures, the engineering time can significantly shorten, and has saved the duration.The PVC material of chimney barrel itself has very strong etch-proof performance, without other preservative treatment, compares and need do special antiseptic telescopic concrete chimney, can significantly reduce installation cost.
