Abstract
Disclosed is a concrete chimney bottom integral steel flue, which comprises a chimney (6), and is characterized in that a steel flue (4) is arranged on the internal surface of the bottom part of chimney (6), two flue gas inlets (1) access into the steel flue (4), a drainage device (3) is disposed at the bottom part of the steel flue (4), and the steel flue (4) overspreads the bottom part of the whole chimney (6). The utility model overcomes the difficult problem of concrete contraction joint handling, and also solves the problem of damage to the chimney due to water leakage of the chimney. The chimney bottom steel flue is like a funnel and collects corrosive condensate separated out from wet flue gas to the bottom part of the chimney, and the drainage device (3) is arranged at the bottom part of the steel flue (4). Collected water is drained to the outside of the chimney through the drainage device at the bottom part of flue.
Description
Technical field
The utility model is applicable to the anticorrosion and seal reconstruction in concrete chimney bottom after WFGD (limestone-gypsum wet process of FGD island) is set up in the steam power station.More particularly it is a kind of concrete chimney bottom integrated steel inner cylinder.
Background technology
Conventional concrete inner core chimney is used for the dry flue gas that exhaust temperature is about 130 ℃-150 ℃, after setting up WFGD (limestone-gypsum wet process of FGD island), discharging be 40 ℃-60 ℃ supersaturation wet flue gas.Contain corrosive liquids such as a certain amount of sulfuric acid, sulfurous acid, hydrochloric acid, nitric acid, hydrofluoric acid in the flue gas.
Because variations in temperature can cause thermal expansion, between concrete chimney inlet and the breeching, leave the expansion slit that is called shrinkage joint or structural joint between the dust stratification platform of bottom and the chimney jambs.The supersaturation wet flue gas has been separated out the water that a large amount of liquid state contains acid solution because the temperature of flowing through behind the flue reduces, and these liquid waters collect on the dust stratification platform of the bottom that is positioned at chimney.If improved chimney is poorly sealed, the acid solution that wet flue gas is separated out will damage chimney by the expansion slot leakage.
Conventional corrosion protection design with polyurethane foam agent stuff up a crack, is filled out embedding with the modified silicon rubber of expansion sealing rod and acidproof heat-proof earlier again at the shrinkage joint or the structural joint place, and outermost layer is protected with the polytetrafluoroethylene (PTFE) rubber tile.Such processing was usually lost efficacy at the shrinkage joint of chimney bottom, and the acid solution that flue gas is separated out damages chimney by the expansion slot leakage.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned existing disadvantages of background technology part, and a kind of wet chimney bottom steel inner cylinder structure is provided.
The purpose of this utility model reaches by following measure: concrete chimney bottom integrated steel inner cylinder, it comprises chimney, it is characterized in that steel inner cylinder being arranged at the chimney bottom inner surface, there are two gas approach to feed in the steel inner cylinder, dewatering installation is arranged at the bottom of described steel inner cylinder, and steel inner cylinder is covered with the bottom of whole chimney.
In technique scheme, there is flange the upper end of described steel inner cylinder, and described flange embeds chimney.
In technique scheme, reinforcing rib is arranged around the cylindrical of described steel inner cylinder.
In technique scheme, the slope that discharges water, the bottom of described steel inner cylinder, the described sloping low dot location that discharges water has dewatering installation.
The bottom that the water that the utility model chimney bottom steel inner cylinder is separated out wet flue gas as a funnel is collected chimney, it is recycling that the gutter by interior tube bottom is recovered to desulphurization system with the water of collecting.The utility model has been walked around the difficult problem that concrete extension joint is handled, and has solved the problem that chimney leaks chimney is destroyed.
Description of drawings
Fig. 1 is the structural representation of the utility model concrete chimney bottom integrated steel inner cylinder.
1. gas approach among the figure, 2. reinforcing rib, 3. dewatering installation, 4. steel inner cylinder, the slope that 5. discharges water, 6. chimney, 7. flange.
The specific embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not constitute to qualification of the present utility model, only do for example.Simultaneously by illustrating that advantage of the present utility model will become clear more and understanding easily.
Consult accompanying drawing as can be known: the utility model concrete chimney bottom integrated steel inner cylinder, it comprises chimney 6, at chimney 6 bottom interior surfaces a steel inner cylinder 4 is arranged, there are two gas approach 1 to feed in the steel inner cylinder 4, steel inner cylinder 4 is used to collect corrosive condensate liquid that has that saturated wet flue gas separates out, and by the dewatering installation that is positioned at minimum point condensate liquid is drained into outside the chimney stack.Dewatering installation 3 is arranged at the bottom of steel inner cylinder, and steel inner cylinder 4 is covered with the bottom (space between steel inner cylinder 4 and the chimney 6 is an access path) of whole chimney 6.
There is the flange 7 that embeds chimney the upper end of steel inner cylinder 4, embed the flange 7 of chimney and can adopt the sealing of elasticity anti-corrosive rubber with the condensate water that prevents the chimney wall by the gap leakage between steel inner cylinder and the chimney wall to the chimney outside.Around the cylindrical of steel inner cylinder 4 reinforcing rib 2 is arranged, reinforcing rib 2 can be strengthened the fastness of steel inner cylinder.
The bottom of steel inner cylinder 4 discharges water sloping 5 (as shown in Figure 1).The nadir of the bottom of steel inner cylinder 4 has dewatering installation 3.
Set up the whole steel inner cylinder that is full of whole stack cross section in the bottom of chimney.Steel work makes hardware, has advantages such as good seal performance, free from flaw with respect to concrete structure.Therefore, if do not consider cost factor, the first-selection of the various often liquid of steel work, gas container.The adhesive power of anticorrosive paint on steel work is much larger than concrete structure in addition.So the utility model has well solved the sealing problem of concrete chimney.
