Abstract
The utility model discloses a sectional-type single-barrel chimney with a concrete structure, comprising a concrete shell. The sectional-type single-barrel chimney is characterized in that a first inner barrel is arranged in the concrete shell, the first inner barrel is connected with a second inner barrel via an annular platform, and a flue opening is arranged on the second inner barrel. The sectional-type single-barrel chimney disclosed by the utility model has the advantages of being energy-saving and environment-friendly, wide in application range, simple and convenient in construction, and low in cost.
Description
Technical field
The utility model relates to a kind of segmented monotubular concrete structure chimney, belongs to heavy aseptic technic field.
Background technology
Along with the raising of country to environmental requirement, coal fired power generation unit universal demand is installed desulfurizer, and desulfurizer adopts wet processing more; Flue gas behind the installation wet desulfurization system has very strong corrosivity usually; Corrosion to chimney is very obvious, and early stage domestic most chimney adopts monotubular formula reinforced concrete structure, behind the installation desulphurization plant; Chimney need carry out preservative treatment, and processing mode commonly used is for directly carrying out anticorrosion on wall or establishing the way of inner core in chimney inside again.Directly on barrel, carry out anticorrosionly, have the problem that anticorrosion area is big, cost is high, when liner need be removed, exist the bottom insulation to require problems such as height again; Again there is the high problem of cost equally in the way of establishing inner core in chimney inside, and difficulty of construction is big in addition, and generally limits so far owing to chimney breast; Inner diameter of steel flue is less; Flue gas flow rate is big, thereby causes the chimney pressure drop big, and energy consumption is high; Form " acid rain " because flow velocity causes the chimney acid solution to be entrained in the chimney periphery greatly in addition, influence the chimney surrounding enviroment.
Summary of the invention
The purpose of the utility model is to solve barrel to be carried out anticorrosion, has problems such as cost is high, difficulty of construction is big, and a kind of energy-conserving and environment-protective, applied widely, easy construction, segmented monotubular concrete structure chimney that cost is low are provided.
In order to achieve the above object, the utility model provides a kind of segmented monotubular concrete structure chimney, comprises concrete shell; It is characterized in that; Concrete shell inside is provided with first inner core, and first inner core is connected with second inner core through ring-shaped platform, and second inner core is provided with flue opening.
The utility model is that Lower Half is established an inner core in addition in the monotubular tapered chimney; The inner core that utilizes original monotubular chimney upper and lower to establish forms exhaust gases passes; Ring-shaped platform connects two sections chimneys as intermediate location, and is heavy and form a continuous discharge flue.Former chimney top is carried out anticorrosion, the inner core that newly set up the bottom, ring-shaped platform all will carry out anticorrosion.The utlity model has following advantage: (1) is applied widely: can be used for domestic a large amount of concrete monotubular tapered chimney.(2) lower energy consumption: can utilize former chimney top discharge area to greatest extent.(3) environmental protection: can reduce flue gas flow rate through increasing logical cigarette diameter, reduce because of carrying " acid rain " of generation secretly.(4) easy construction:, reduced difficulty of construction owing to effectively reduce the inner core height of newly establishing.(5) cost is lower.
Description of drawings
Fig. 1 is a kind of structural representation of segmented monotubular concrete structure chimney.
Among the figure: 1 is concrete shell, and 2 is ring-shaped platform, and 3 is second inner core, and 4 is flue opening, and 5 is first inner core.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
Embodiment 1
As shown in Figure 1, be a kind of structural representation of segmented monotubular concrete structure chimney.The utility model is a kind of segmented monotubular concrete structure chimney, at first with former concrete chimney liner dismounting, former isolation layer refractory brick of concrete chimney inwall or former anticorrosive coat is cleaned out, and exposes concrete shell 1, and does suitable repairing.At one second inner core 3 of the inner setting of concrete chimney; Second inner core 3 highly is lower than former chimney height; Concrete shell 1 inwall bracket place is equipped with ring-shaped platform 2; Ring-shaped platform 2 is connected with second inner core, 3 tops, and connection can be adopted direct welding, anchoring or adopt the expansion joint mode that is flexible coupling.Ring-shaped platform 2 is as first inner core 5 on former chimney top and the intermediate location of second inner core 3.Second inner core 3 and first inner core 5 form a continuous passage, and ring-shaped platform 2 internal diameters are close with the chimney diameter of newly establishing, and the bottom position of second inner core 3 has flue opening 4, is connected with flue.Second inner core 3 can adopt vertical type or suspended structure, and material adopts materials such as carbon steel, titanium steel composite board, glass fiber reinforced plastic.
After adopting the utility model, flue gas gets in second inner core 3 through flue, through the processing of wet desulfurization system; Generation has very strong corrosive liquid; Because second inner core 3 blocks it, make this liquid only in second inner core 3, prevented the corrosion of concrete shell 1 bottom.The surface area that the surface area of second inner core 3 is compared concrete shell 1 bottom is little, has reduced and need carry out antiseptic area, makes that the cost when changing is lower.
Claims (1)
1. segmented monotubular concrete structure chimney; Comprise concrete shell (1), it is characterized in that concrete shell (1) inside is provided with first inner core (5); First inner core (5) is connected with second inner core (3) through ring-shaped platform (2), and second inner core (3) is provided with flue opening (4).
