Description
Technical field
Water circulation cooling field is the utility model is related to, more particularly to a kind of circulating line cooling device.
Background technology
Firepower electrical plant coal-burning boiler needs the substantial amounts of coal that burns daily, has substantial amounts of cinder to be arranged from boiler daily
Go out, and the cinder temperature discharged is very high, about 900 DEG C of high temperature if being expelled directly out, can damage to external environment,
The loss of heat can also be caused.At present, mainly cinder is cooled by a kind of circulating line cooling device, by by cinder
Heat transfer into cooling water, reduce the temperature of cinder, then discharge it, and the cooling water after heating is used for boiler etc.
Place, realizes the recycling of heat, reduces cost and reduces the harm to environment.
Cinder is generally discharged into by prior art from one end of inclined inner barrel, then is discharged from the other end, in inner barrel
It is provided through cooling water pipe.The outer barrel that connection is formed with inner cylinder is rotated, the cinder into inner barrel is connect with cooling water pipe
After touch, heat transfer is constantly carried out, so that the temperature of the water in cooling water pipe constantly raises.However, in rotation inner cylinder and outside
During the entirety that cylinder is formed, cinder is constantly discharged with angle of inclination to the relatively low one end of inner barrel, and part is close to inner cylinder inwall
Cinder be also difficult to fully be contacted with cooling water pipe, and then be difficult to more be filled with the cooling water in cooling water pipe
The heat transfer divided, cause the problem of heat transference efficiency is not high enough, the temperature of the cinder of discharge is higher.
Utility model content

Heat transfer effect.And there is gap between adjacent guide pad, be not easy to make cinder in heaps, be easy to disperse cinder, by heat compared with
Equably to distribute, heat transfer effect is favorably improved.On the other hand, cooling tube connects with the cavity inside cooling fan blades, and
Coolant enters in cooling tube from feed tube, and redisperse increases specific surface area into cooling fan, help to make cooling tube with it is cold
But the coolant inside fan blades absorbs uniformly and rapidly the heat of cinder in inner barrel, so make the temperature of the cinder of discharge compared with
It is low, reach the purpose of heat recovery and energy-conserving and environment-protective.
More preferably：The cooling fan blades is set for helical form.
Using said structure, connection between the integrated connection intensity and effect, with cooling tube of cooling fan blades is enhanced more
It is more, it is easy to the smooth inlet and outlet of coolant.Meanwhile the overall specific surface area of cooling fan blades is added, it is favorably improved
The thermal conduction effect of coolant.
More preferably：Cavity thickness of the cooling fan blades close to cooling tube one end is less than cooling fan blades close to inner cylinder
The cavity thickness of the inwall side of body.
Using said structure, when outer cylinder body together rotates with inner barrel around same direction, substantial amounts of cinder is got rid of to interior
The inwall direction of cylinder, and it is larger to cool down cavity thickness of the fan blades close to the inwall side of inner barrel, contribute to near inwall
Cinder carry out more sufficient heat transfer, it helps reduce the temperature of cinder, make the temperature of the cinder from slag notch discharge
It is relatively low.
More preferably：The driving structure includes annular rack, the first motor and first being arranged on outer cylinder body
Motor connection and with annular rack meshed gears.
Using said structure, the first motor-driven gear rotates, and constantly engage with annular rack, so drive outer cylinder body and
Inner barrel together rotates, and improves the stability and uniformity rotated to cinder in inner barrel.
More preferably：The position limiting structure includes support base, the circular orbit being arranged at outside outer cylinder body, is set up in
The spacing runner of support base, the spacing runner coordinate with circular orbit.
Using said structure, position limiting structure cooperates with driving structure, when the first motor drives outer cylinder body and inner barrel
Together rotate, spacing runner is caught in circular orbit, is added stationarity of the outer cylinder body in rotation process, is helped to carry
The uniformity and adequacy that cinder in high inner barrel is reversed.
More preferably：One end of the outer cylinder body, which is extended, reinforcement, and the reinforcement extends through annular
Rack and circular orbit.
Using said structure, help to increase the bulk strength of outer cylinder body, extend the service life of whole system.
More preferably：The angle of inclination of the outer cylinder body and inner barrel is 10-15 °.
Using said structure, in the case that the cinder that helps to make to enter in inner barrel is reversed on one side, moreover it is possible to gradually
Discharged to slag notch.
More preferably：The outside of the outer cylinder body is coated with heat-insulation layer, and the heat-insulation layer chooses froth bed or asbestos
Layer.
Using said structure, inner barrel and outer cylinder body form connection, reduce the possibility that heat in inner barrel outwards distributes.
And froth bed or asbestos layer are respectively provided with good heat insulation effect, the heat of cinder in inner barrel is further preserves, helps to make
The coolant that cinder is transferred heat in cooling tube, cooling fan blades, makes coolant obtain higher temperature, so as to promote waste heat
Recycling.
In summary, the utility model has the advantages that：
By guidance set, cooling tube and the mutual cooperation for cooling down fan blades, help to extend high temperature coal slag in inner barrel
Holdup time, so as to improve to the heat transfer effect between coolant and high temperature coal slag, and make the cinder temperature of discharge relatively low.
