Abstract
The utility model discloses a water-cooling spiral flow-around type slagging device used for a circulating fluidized bed boiler. The water-cooling spiral flow-around type slagging device comprises an inner pipe, an upper end cover, an upper section of an outer pipe, a connector of a water inlet pipe, a middle section of the outer pipe, an expansion joint, a lower section of the outer pipe, a lower end cover, a slagging door, a connector of a water outlet pipe which are all connected in sequence in a welding mode, wherein spiral blades are welded to the inner pipe. The water-cooling spiral flow-around type slagging device can strengthen heat transfer and reduce loss of heat dissipation.
Description
Affiliated technical field
The utility model relates to a kind of deslagging device for CFBB.
Background technology
The deslagging device that present CFBB is used is linked in sequence and is formed by inner tube, water dispensing board, deflection plate, upper end cover, outer tube top, outer tube middle part, expansion joint, outer tube bottom, bottom end cover, admitting pipe joint, titting water outlet, slagging door.Cooling water enters from admitting pipe joint, is drawn by titting water outlet after flowing through water dispensing board, deflection plate, and the bulky grain slag of Fluidized Boiler Bed inner bottom part is entered by inner tube top, go out from the slagging door row, if the use slag cooler can be without the slagging door, the inner tube bottom directly is connected with slag cooler.Because the slag temperature is very high, so the inner tube wall temperature is also very high, can reduce tube wall temperature after the employing water cooling, reduce radiation loss.But because water distribution is inhomogeneous, cause mobile inhomogeneous between inner and outer pipes of cooling water, short circuit is caused more greatly in the gap between deflection plate and the outer tube in addition, make the part cooling water with just directly outflow of the abundant heat exchange of inner tube, so cooling effect is relatively poor.
Summary of the invention
The purpose of this utility model provide a kind of water-cooling spiral flow around type deslagging device solve the existing mobile inhomogeneous and part cooling water of deslagging device cooling water between inner and outer pipes not with the problem of the abundant heat exchange of inner tube with regard to direct outflow, this deslagging device has increased the heat exchange area under the outer tube equal height, Uniform Flow in the whole helical ducts of cooling water between inner and outer pipes, good cooling results.
The technical scheme that its technical problem that solves the utility model adopts is: upper end cover, outer tube epimere, admitting pipe joint weld connection mutually, outer tube stage casing, expansion joint, outer tube hypomere, bottom end cover, titting water outlet be mutually weldering connection successively, after helical blade and the inner tube welding inner tube upper end is inserted in the hole of upper end cover, the Kong Zhongxiang weldering that bottom end cover is inserted in the inner tube lower end connects, again with outer tube stage casing and the welding of outer tube epimere, and the slagging door of burn-oning in the lower end of inner tube, so just formed water-cooling spiral flow around type deslagging device.
Owing to being welded with helical blade on the inner tube, after cooling water is entered by admitting pipe joint, will stream and descend along the inner tube spiral, in flow process, current constantly impact outer tube wall to carry out the disturbance mixing and has strengthened heat transfer, and inner tube has been welded after the helical blade in addition, increased heat transfer area, therefore under identical inner and outer pipes diameter, height and identical import slag temperature, import coolant water temperature and flow, the heat that cooling water is taken away is more, and the tube wall temperature of inner tube is more with regard to reduction also.
The beneficial effects of the utility model are, have strengthened heat transfer, have reduced radiation loss, and the hot environment when making artificial deslagging is improved.
Description of drawings
Below in conjunction with accompanying drawing the utility model structure is further specified.
Figure of description is structural map of the present utility model.
1. slagging doors among the figure, 2. bottom end cover, 3. expansion joint, 4. helical blade, 5. inner tube, 6. upper end cover, 7. admitting pipe joint, 8. outer tube epimere, 9. outer tube stage casing, 10. outer tube hypomere, 11. titting water outlets.
The specific embodiment
Upper end cover (6), outer tube epimere (8), admitting pipe joint (7) welds connection mutually, outer tube stage casing (9), expansion joint (3), outer tube hypomere (10), bottom end cover (2), titting water outlet (11) is mutually weldering connection successively, after helical blade (4) welds with inner tube (5) inner tube (5) upper end is inserted in the hole of upper end cover (6), the Kong Zhongxiang weldering that bottom end cover (2) is inserted in inner tube (5) lower end connects, again with outer tube stage casing (9) and outer tube epimere (8) welding, and the slagging door (1) of burn-oning in the lower end of inner tube (5), so just formed water-cooling spiral flow around type deslagging device.
Owing to being welded with helical blade (4) on the inner tube (5), after cooling water is entered by admitting pipe joint (7), will rotational flow, stream and descend along inner tube (5) spiral, in flow process, current constantly impact outer tube wall to carry out the disturbance mixing and has strengthened heat transfer, inner tube (5) has been welded after the helical blade (4) in addition, increased heat transfer area, therefore at identical inner and outer pipes diameter, height and identical import slag temperature, under import coolant water temperature and the flow, the heat that cooling water is taken away is more, and (it is more that 5 tube wall temperature also just reduces inner tube.
Structural map of the present utility model is the structure of the artificial deslagging of expression band slagging door (1), and when being used for mechanical deslagging, inner tube (5) bottom directly is connected with slag cooler.
Claims (1)
1. water-cooling spiral flow around type deslagging device, upper end cover, outer tube epimere, admitting pipe joint weld connection mutually, outer tube stage casing, expansion joint, outer tube hypomere, bottom end cover, titting water outlet be mutually weldering connection successively, the inner tube upper end is inserted in the hole of upper end cover, the Kong Zhongxiang weldering that bottom end cover is inserted in the inner tube lower end connects, the slagging door of burn-oning again with the welding of outer tube stage casing and outer tube epimere, and in the lower end of inner tube, it is characterized in that: helical blade welds with inner tube.
