Abstract
The utility model discloses a kind of Anti-corrosive chimney, comprise chimney body, it is characterized in that: described chimney body comprises main frame layer, external anti-corrosion layer, heat-insulation layer and interior anticorrosive coat from outside to inside successively; The Thickness Ratio of described main frame layer, external anti-corrosion layer, heat-insulation layer and interior anticorrosive coat is (3-5): (1-2): (1-2): (3-5).The utility model cost is low, and structure is simple, easy construction, and anti-corrosion life is long, and meanwhile, armored concrete consumption is little, does not have expensive liner, comprehensive power plant 30 years durability analysises, and investment is very low with maintenance cost, and maintenance workload is little, achieves energy-saving and cost-reducing.
Description
Technical field
The utility model belongs to chimney field, specifically, relates to a kind of Anti-corrosive chimney.
Background technology
Chimney of electric plant is mostly reinforced concrete structure before not installing wet desulphurization, along with national environmental protection policy is more and more tighter, the wet desulphurization that removal efficiency is high is all selected by most power plant, and the exhaust gas temperature of chimney is inevitable lower than acid dew point, causes chimney to be corroded.
The multiplex inner surface of built chimney anticorrosion smears acid resistant adhesive mortar or silica gel pasted with ceramic veneer vitrified tile, small investment but maintenance workload is large.Newly-built chimney many employings steel inner cylinder reinforced concrete structure, steel inner cylinder material mostly is carbon steel liner C276, carbon steel titanium lined plate or adopts titanium steel composite board, involves great expense.
Utility model content
The technical problems to be solved in the utility model overcomes above-mentioned defect, provides that a kind of cost is low, structure is simple, easy construction, anti-corrosion life is long, maintenance workload is little, achieves energy-saving and cost-reducing Anti-corrosive chimney.
For solving the problem, the technical scheme that the utility model adopts is:
A kind of Anti-corrosive chimney, comprises chimney body, it is characterized in that: described chimney body comprises main frame layer, external anti-corrosion layer, heat-insulation layer and interior anticorrosive coat from outside to inside successively; The Thickness Ratio of described main frame layer, external anti-corrosion layer, heat-insulation layer and interior anticorrosive coat is (3-5): (1-2): (1-2): (3-5).
As a kind of technical scheme of optimization, described main frame layer is the reinforced concrete structure layer that reinforcing bar and concrete coagulation are made.
As a kind of technical scheme of optimization, described external anti-corrosion layer is the Corrosion Protection of Fiber Reinforced Plastics layer that glass-reinforced plastic material is made.
As a kind of technical scheme of optimization, described heat-insulation layer is the heat-insulation layer be made up of insulation material.
As a kind of technical scheme of optimization, described interior anticorrosive coat is the ceramics vitrified brick anticorrosive coat be built into by ceramics vitrified brick.
As a kind of technical scheme of optimization, the Thickness Ratio of described main frame layer, external anti-corrosion layer, heat-insulation layer and interior anticorrosive coat is 4: 1: 1: 4.
Owing to have employed technique scheme, compared with prior art, the utility model cost is low, structure is simple, easy construction, anti-corrosion life is long, simultaneously, armored concrete consumption is little, do not have expensive liner, comprehensive power plant 30 years durability analysises, investment is very low with maintenance cost, maintenance workload is little, achieves energy-saving and cost-reducing.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Detailed description of the invention
Embodiment:
As shown in Figure 1, a kind of Anti-corrosive chimney, comprises chimney body, and described chimney body comprises main frame layer 1, external anti-corrosion layer 2, heat-insulation layer 3 and interior anticorrosive coat 4 from outside to inside successively.The Thickness Ratio of described main frame layer 1, external anti-corrosion layer 2, heat-insulation layer 3 and interior anticorrosive coat 4 is (3-5): (1-2): (1-2): (3-5).
In the present embodiment, consider actual use, described main frame layer is the reinforced concrete structure layer that reinforcing bar and concrete coagulation are made.Described external anti-corrosion layer is the Corrosion Protection of Fiber Reinforced Plastics layer that glass-reinforced plastic material is made.Described heat-insulation layer is the heat-insulation layer be made up of insulation material.Described interior anticorrosive coat is the ceramics vitrified brick anticorrosive coat be built into by ceramics vitrified brick.
The Thickness Ratio of described main frame layer, external anti-corrosion layer, heat-insulation layer and interior anticorrosive coat is 4: 1: 1: 4.
The utility model cost is low, and structure is simple, easy construction, and anti-corrosion life is long, and meanwhile, armored concrete consumption is little, does not have expensive liner, comprehensive power plant 30 years durability analysises, and investment is very low with maintenance cost, and maintenance workload is little, achieves energy-saving and cost-reducing.
The utility model is not limited to above-mentioned preferred embodiment, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or akin technical scheme with the utility model, all belongs to protection domain of the present utility model.
