The specific embodiment
Below in conjunction with embodiment shown in the drawings the utility model is described further:
As shown in Figure 1-Figure 3, external fluid-bed heat exchanger comprises charging aperture 1, discharging opening 11, Heat Room 6, Heat Room 7, returning charge passage 16, superheater pipe 12 and bellows 2, bellows 3, bellows 4.Charging aperture 1 is located at the middle part, front upper place.Charging aperture 1 both sides are Heat Room 6.Charging aperture 1 back is a Heat Room 7.Isolate by partition wall 9 between Heat Room 6, the Heat Room 7.Have the through hole 14 that is communicated with Heat Room 6 and Heat Room 7 on the partition wall 9.Middle part, Heat Room 7 rears is a discharging opening 11.Discharging opening 11 both sides are returning charge passage 16.Isolate by partition wall 10 between discharging opening 11, returning charge passage 16 and the Heat Room 7.Have the through hole 8 that is communicated with Heat Room 7 and discharging opening 11 on the partition wall 10, also have the through hole 17 that is communicated with Heat Room 7 and returning charge passage 16.Isolate by partition wall 15 between discharging opening 11 and the both sides returning charge passage 16.Have the through hole 18 that is communicated with returning charge passage 16 and discharging opening 11 on the partition wall 15.The bottom of Heat Room 6, Heat Room 7, returning charge passage 16 is provided with bellows 2, bellows 3, bellows 4 respectively.Bellows 2, bellows 3, bellows 4 are communicated with Heat Room 6, Heat Room 7, returning charge passage 16 respectively by blast cap 5.Laterally place superheater pipe 13 in the Heat Room 6.The vertical superheater pipe 12 of placing in the Heat Room 7.Superheater pipe 12, superheater pipe 13 can be used coiled pipe.
During work, high-temperature solid particle enters from charging aperture 1, and the air that fluidisation is used enters heat exchanger through bellows 2,3, and when not to bellows 4 air feeds, fluidization air evenly sprays in the heat exchanger by blast cap 5, makes the solid particle fluidisation in the heat exchanger Heat Room 6,7.Under the effect of fluidization air, after the solid particle of high temperature entered Heat Room 6 from charging aperture 1, the through hole 14 from partition wall 9 entered Heat Room 7, entered discharging opening 11 through the through hole 8 on the partition wall 10, left heat exchanger then and returned boiler furnace.Under this kind method of operation in the heat exchanger height of the bed of material be about H1.Arrange superheater pipe 12,13 (coiled pipes) in the Heat Room 6,7, the solid particle of high temperature was passing through Heat Room at 6,7 o'clock, and with the working medium (water vapour) that flow in the heat transferred superheater pipe 12,13, working medium is left heat exchanger after reaching overheated parameter value.When needs are adjusted the superheater caloric receptivity, can give bellows 4 air feeds, in this moment external heat exchanger the interior solid particle of returning charge passage 16 also fluidisation get up.High-temperature solid particle is entering returning charge passage 16 from Heat Room 7 by the through hole on the partition wall 10 17 under the effect of fluidization air, leaves heat exchanger again after the through hole on the partition wall 15 18 enters discharging opening 11.Under this kind method of operation in the external heat exchanger height of the bed of material be about H2.The change of bed depth in the external heat exchanger, directly influenced the contact area of superheater pipe 12,13 and high-temperature solid particle, promptly change the heat exchange amount between the working medium in high-temperature solid particle and the superheater pipe 12,13, thereby reached the purpose of adjusting superheater pipe 12,13 caloric receptivities.
Because external fluid-bed heat exchanger is designed to the module combinations form, all pipes are disassembled and assembled freely as required, can also adjust heating surface area by adjusting the insertion depth of pipe in heat exchanger, thereby further adjust the heat exchange amount.
Can be provided with manhole, various measured hole as required on the heat exchanger.
