Abstract
The utility model relates to a converter exhaust-heat boiler fire door section flue, its characterized in that: the flue is in a horn mouth shape, a plurality of heated tubes are uniformly distributed in the flue, each heated tube consists of a large-caliber heated tube (3) and a small-caliber heated tube (5), one end of the large-caliber heated tube (3) is welded with a header (1) at the lower part of the flue, the other end of the large-caliber heated tube (3) is connected with the small-caliber heated tube (5) through an eccentric reducing joint (4), and a partition plate (2) is welded between every two adjacent large-caliber heated tubes (3). According to the flue at the furnace mouth section of the converter waste heat boiler, a single heated pipe is divided into two heated pipes with different calibers, the caliber of the heated pipe at the upper part is the same as that of the conventional heated pipe, and the caliber of the heated pipe at the bell mouth is larger, so that the distance between the heated pipes at the bell mouth is reduced, the maximum width of the partition plate can be correspondingly reduced, the partition plate can be fully cooled, and the partition plate can be prevented from being burnt and the heated pipe can be prevented from being pulled to crack.
Description
Technical field
The utility model relates to a kind of flue, is a kind of fire door section flue of steel-smelting revolving furnace smoke canal formula waste heat boiler, belongs to steelmaking equipment technical field.
Background technology
In order to improve boiler efficiency, shell boiler develops into tubular boiler gradually, to increase heat transfer area.Pot water by drum through downtake flow into below casing in, distribute to each tube bank by casing, these tube bank in water constantly absorb heat energy, be pooled in casing above and flow back in drum again, we call header or header upper and lower casing.
Purifying smoke of steel converter retrieving arrangement arranges the object of waste heat boiler, is to reduce flue-gas temperature, and for creating conditions to flue gas ash removal further, energy recovered flue gas sensible heat, produces steam simultaneously.At present, many mini-medium BOF plants adopt the treatment process of flue gas and partly fire method, and the mid-term coefficient of excess air of namely blowing controls between 0.15 ~ 0.3, and this method can be removed from and fallen cover, fills the complex operations such as nitrogen and precise hard_drawn tuhes.Therefore many mini-medium BOF plants waste heat boilers eliminate movable gas hood, are lengthened the bottom of fire door section flue, and make hydraucone form, to facilitate seizure flue gas.
The structure of flue is generally membrane wall structure by Tube-sheet Welding, because the upper and lower opening diameter difference of the flue of hydraucone form is larger, cause the non-constant width of dividing plate (needing > 40mm) be placed between heat pipe, as Fig. 3 and Fig. 4, and fire door section flue is in combustion zone above converter, so often there is the situation of scaling loss dividing plate and drawing crack heat pipe.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides and can effectively reduce spacer width, prevents a kind of Converter Residual Heat Boiler fire door section flue of dividing plate scaling loss and heat pipe drawing crack.
The purpose of this utility model is achieved in that
A kind of Converter Residual Heat Boiler fire door section flue, this flue is toroidal, some heat pipes are evenly equipped with in flue, wherein each heat pipe is made up of heavy caliber heat pipe and small-bore heat pipe, one end of heavy caliber heat pipe and the header welding of flue bottom, the other end of heavy caliber heat pipe is connected with small-bore heat pipe by eccentric reducing joint, is welded with dividing plate between adjacent two heavy caliber heat pipes.
Small-bore heat pipe and heavy caliber heat pipe keep concordant inside flue.
The specification of eccentric reducing joint is DN50 × 32 II R(E).
Dividing plate is wedge shape.
Dividing plate is its widest part position near one end of header.
A kind of Converter Residual Heat Boiler fire door of the utility model section flue has the following advantages:
This kind of Converter Residual Heat Boiler fire door section flue is by the rational modification of structure, single heat pipe is divided into two portions heat pipe that caliber size is different, and by eccentric reducer union, two portions heat pipe is connected, the caliber of the heat pipe on top is as in the past, and the caliber of hydraucone place heat pipe is larger, so just, make the pitch smaller between hydraucone place heat pipe, the maximum width of dividing plate can correspondingly be reduced, dividing plate fully can be cooled, thus prevent dividing plate scaling loss and heat pipe drawing crack.
Accompanying drawing explanation

Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the sectional view of original Converter Residual Heat Boiler fire door section flue.
Fig. 4 is the B-B sectional view of Fig. 3.
In figure: header 1, dividing plate 2, heavy caliber heat pipe 3, eccentric reducing joint 4, small-bore heat pipe 5, maximum width H.
Embodiment
See Fig. 1 and Fig. 2, the utility model relates to a kind of Converter Residual Heat Boiler fire door section flue, this flue is toroidal, some heat pipes are evenly equipped with in flue, wherein each heat pipe is made up of heavy caliber heat pipe 3 and small-bore heat pipe 5, one end of heavy caliber heat pipe 3 is welded with the header 1 of flue bottom, the other end of heavy caliber heat pipe 3 is DN50 × 32 II R(E by specification) eccentric reducing joint 4 is connected with small-bore heat pipe 5, small-bore heat pipe 5 and heavy caliber heat pipe 3 keep concordant inside flue, dividing plate 2 is welded with between adjacent two heavy caliber heat pipes 3, this dividing plate 2 is in wedge shape, dividing plate 2 is its widest part position near one end of header 1, this maximum width is H.
This kind of Converter Residual Heat Boiler fire door section flue is by the rational modification of structure, single heat pipe is divided into two portions heat pipe that caliber size is different, and by eccentric reducer union, two portions heat pipe is connected, the caliber of the heat pipe on top is as in the past, and the caliber of hydraucone place heat pipe is larger, so just, make the pitch smaller between hydraucone place heat pipe, the maximum width of dividing plate can correspondingly be reduced, dividing plate fully can be cooled, thus prevent dividing plate scaling loss and heat pipe drawing crack.
