Abstract
The utility model discloses a water-cooled fixing device. The water-cooled fixing device is characterized in that the water-cooled fixing device comprises a lower beam, a vertical beam and an upper beam, wherein two ends of the vertical beam are respectively connected with the lower beam and the upper beam. The vertical beam is provided with a guide cylinder which is used for being inserted by one end of a heat transfer surface heater. The outer portion of a flue is provided with a locking snap ring and a locking lining plate. The locking snap ring and the locking lining plate are used for fixing one end of the heat transfer surface heater. The lower beam and the upper beam penetrate through the flue and are fixed on a beam lining plate through a beam snap ring. The water-cooled fixed device abandons a traditional hanging fixing mode, achieves the fixation of a heating surface in the inner portion of the flue. The water-cooled fixed device has the advantages of being simple and compact in structure and low in cost.
Description
Technical field
The utility model relates to the fixture of heat-transfer surface in a kind of waste heat reclaiming flue.
Background technology
Often utilize the flue wall to absorb the heat of high-temperature flue gas in the flue as heat-transfer surface in the waste heat recovery field, such as converter evaporation cooling air flue, electric furnace water-cooling flue etc. in the smelter.In residual heat flue, as heat exchange area, heat exchange area is limited with walling of flue for flue gas, and residual heat flue outlet cigarette temperature when dropping to below 600 ℃ for the flue-gas temperature that makes discharge, need to increase heat-transfer surface generally at 850 ℃ ~ 900 ℃ in flue.
The fixture of existing Boiler Furnace internal heating surface adopts suspending way more, and its primary structure comprises frame girder, flat board, suspension hook and clamp ring.Suspension hook be welded on the frame girder upper flat plate and weld mutually, the header of heat-transfer surface or heat pipe are hung on the suspension hook after with the clamp ring clamping in the stove, heat-transfer surface weight is passed on the frame girder, and by frame supports, the superheater of upper boiler and reheater adopts this mode to be hung on the boiler body framework.But existing boiler suspending way is unsuitable for the waste heat reclaiming flue internal heating surface and fixes, and main cause is:
1) waste heat reclaiming flue is installed in the technique factory building, the frameless or column of body, and main support is on the factory building beam column, and flue length is longer, so heat-transfer surface is difficult to hang on the factory building beam column in the flue;
2) for waste heat reclaiming flue, converter waste heat reclaiming flue particularly, the technological operation intermittence is stronger, flue gas flow changes frequent, the interior working-medium water of heating surface is mobile and the vaporization disturbance is large, adopts the suspending way heating surface to be in operation and vibrates easily, is unfavorable for safe and stable operation;
3) realize suspension although can pass flue top cooling wall near the heat-transfer surface the flue top, vibration problem can't solve.
4) also can not adopt suspending way to arrange for the heating surface in the waste heat reclaiming flue that in the technique factory building, is in tilted layout.
The utility model content
The purpose of this utility model provides the water-cooled fixture of heat-transfer surface in a kind of residual heat flue.
To achieve these goals, by the following technical solutions: a kind of water-cooled fixture, it is characterized in that: described device comprises sill, vertical beam and entablature, wherein the two ends of vertical beam connect respectively sill and entablature, be provided with the guide cylinder that inserts for heat-transfer surface header one end on the vertical beam, the outer setting of flue is useful on fixedly shackle and the locking liner plate of heat-transfer surface header one end, and sill and entablature pass flue and be fixed on the crossbeam liner plate by the crossbeam snap ring.
Because the flue gas operating temperature is higher in the residual heat flue, excessive for preventing frame structure stress and deflection, keep the framework reasonable temperature, described sill, vertical beam and entablature inside have the cooling duct, the cross section of cooling duct is circular or square, cooling water is entered by sill, and the vertical beam of flowing through is flowed out by entablature again.
Described sill and entablature are the cross interlaced arrangement, stagger so that lower and upper cross-member passes the residual heat flue position, avoid repeatedly coil pipe of this position residual heat flue water cooling tube, the resistance difference between minimizing and adjacent water cooling tube.
The utility model has been abandoned traditional suspension type fixed form, has realized in flue inside heating surface being fixed, and it is simple in structure, compact, and cost is lower.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view of A-A among Fig. 1.
Among the figure, part 1 is sill, and part 2 is vertical beam, and part 3 is entablature, and part 4 is guide cylinder, and part 5 is the crossbeam snap ring, and part 6 is the crossbeam liner plate, and part 7 is shackle, and part 8 is the locking liner plate.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, vertical beam 2 two ends in the residual heat flue connect respectively sill 1 and entablature 3, and guide cylinder 4 links to each other with vertical beam 2, and heat-transfer surface header one end inserts guide cylinder 4 in the flue, the other end stretches out flue, is fixed on the locking liner plate 8 by shackle 7.Wherein lock liner plate 8 and the welding of flue outer wall.Flue is stretched out at sill 1 and entablature 3 two ends, is fixed on the crossbeam liner plate 6 respectively crossbeam liner plate 6 and the welding of flue outer wall by crossbeam snap ring 5.Pass into cooling water by sill 1, behind vertical beam 2, flowed out by entablature 3.
The utility model mainly is suitable for the fixing of the interior heat-transfer surface of newly-built converter, electric furnace or ferro-alloy furnace waste heat reclaiming flue, also is applicable to increase newly in existing converter, electric furnace or the ferro-alloy furnace flue gas waste heat recovery flue fixing of heat-transfer surface.
