Within the scope of one metastable, while reducing energy consumption, also reduce material consumption and consume with brick.
For achieving the above object, this utility model is achieved through the following technical solutions: a kind of cement is raw
Produce rotary kiln surface heat reclaim unit, adjust including outer housing, water collar, heat exchanger, air blower tube and air quantity
Joint valve, described water collar and outer housing are regular hexagon, are symmetricly set on outside the outer surface of cement rotary kiln,
It is provided with gap between two described water collars, and all and there is gap between the outer surface of rotary kiln, described
Forming a ventilating duct between water collar and rotary kiln surface, water collar is provided with working medium import and working medium goes out
Mouthful, outer housing is a closing case being wrapped in outside water collar, is provided with two cavitys, air blower tube in it
Being connected with a cavity of outer housing and be provided with volume damper in this cavity, heat exchanger is arranged on the another of outer housing
In one cavity, the sender property outlet on described water collar is connected with the hot working fluid import on heat exchanger, described
Water collar both sides inwall be arranged at intervals with length more than water collar diameter 1/2nd, straight less than water collar
The projection in footpath.
Further illustrating, described outer cover inner surface is provided with heat-insulation layer.
Compared with prior art, this utility model has the advantages that this utility model returns at cement
Rotary kiln surface defines a water collar being capable of free convection and tubular heat exchanger combination, is aided with wind
Machine pipeline, it is achieved the step regulation of rotary kiln surface temperature, working medium does not directly contact with rotary kiln, not shadow
Ring the properly functioning of rotary kiln, reclaim heat exchange efficiency high, effective, by the work heated by rotary kiln
The recycling of matter, it is achieved save energy, reduces overall energy consumption, and rotary kiln surface is cooled down, and reaches
Reduce material consumption and the purpose of brick consumption, be conducive to improving the working life of rotary kiln.Owing to water collar is with outer
Cover, in orthohexagonal geometry, enters the air position shape at hexagon angle of inside and outside ventilating duct
Become whirlpool, enhance heat-transfer effect, extend the air time of staying in air channel, increase recovery
Heat, improves effectiveness of regenerator.Water collar both sides inwall is arranged at intervals with length more than water collar diameter
1/2nd can extend air residence time, preferably to absorb heat less than the projection of water collar diameter
Amount.
Accompanying drawing explanation
Fig. 1 is for illustrating showing of this utility model embodiment manufacture of cement rotary kiln surface heat reclaim unit
It is intended to.
Parts title and sequence number in figure: 1-rotary kiln 2-outer housing 3-water collar 4-air blower tube 5-changes
Hot device 6-volume damper 7-ventilating duct 8-working medium import 9-sender property outlet 10-projection.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail, but does not limits
Make protection domain of the present utility model and range of application:
As it is shown in figure 1, a kind of manufacture of cement rotary kiln surface heat reclaim unit, including outer housing 2, water-cooled
Set 3, heat exchanger 5, air blower tube 4 and volume damper 6, water collar 3, in regular hexagon, is symmetricly set on
Outside the outer surface of cement rotary kiln 1, between two water collars 3, be provided with gap, and all with rotary kiln 1
There is gap between outer surface, between water collar 3 and rotary kiln 1 surface, form a ventilating duct 7, water-cooled
Set 3 is the parts that a similar water pocket is the same, and there is a cavity inside, and it is respectively arranged at two ends with working medium import 8
With sender property outlet 9.Outer housing 2 is a closing case being wrapped in outside water collar 3, is provided with two in it
Cavity, air blower tube 4 is connected with a cavity of outer housing 2 and is provided with volume damper 6 in this cavity, to adjust
Joint enters the air quantity in overcoat 2 by air blower tube 4.Heat exchanger 5 is arranged in another cavity of outer housing 2,
Working medium in water collar 3 can use serial or parallel connection even by sender property outlet 9 and the working medium in heat exchanger 5
Connect.Heat-insulation layer can be provided with, so that working medium fully absorbs the heat of cement rotary kiln 1 in overcoat 2 interior surface
Exchange with external heat.Water collar 3 both sides inwall relative spacing is provided with length more than the two of water collar 3 diameter
/ mono-projection 10 being less than water collar 3 diameter, makes the gap in water collar 3 become multiple S-shaped, increases cold
Fluid working substance is the time of staying in water collar 3, fully absorbs the heat of cement rotary kiln 1.Due to water collar
3 and outer housing 2 in orthohexagonal geometry, enter ventilating duct air in the position of hexagon angle
Form whirlpool, enhance heat-transfer effect, extend the air time of staying in ventilating duct, increase back
The heat received, improves effectiveness of regenerator.
The material of outer housing 2, water collar 3 and air blower tube 4 can use general boiler steel, it is not necessary to special
Material.Use low boiling working fluid or general working medium in water collar 3 and tubular heat exchanger 5, produce steam
Or high-temperature water.Available high-power blower or the secondary wind of burner after the cold air heating entered in air blower tube 4.
When rotary kiln 1 works, its surface temperature is higher, is now placed in the water-cooled of rotary kiln 1 outer surface
It is passed through the cold fluid working substance of low boiling by working medium import 8 in set 3.When the cold fluid flow in water collar 3 is through returning
The radiations heat energy on rotary kiln 1 surface can be absorbed, the cold flow body in water collar 3 during rotary kiln 1 outer surface space
The tubular heat exchanger 5 on rotary kiln 1 top is entered after Bei Jiare.Meanwhile, cold air is through air blower tube
4 enter the ventilating duct 7 between water collar 3 and rotary kiln 1, heated when flowing through rotary kiln 1 surface,
Absorbing the heat on rotary kiln 1 surface, the air after heating enters outside the pipe of tubular heat exchanger 5, heating
Fluid in pipe in tubular heat exchanger 5, this fluid is from water collar 3, and heated tube fluid is permissible
It is collected utilization, thus has saved the energy, reduce overall energy consumption.By working medium in regulation water collar 3
Flow and the aperture of air blower tube 4 arranged along cement rotary kiln length realize the ladder of rotary kiln surface temperature
Level regulation, fully absorbs the heat radiation on rotary kiln 1 surface.
Above content be combine that this utility model made by concrete preferred implementation the most in detail
Explanation, it is impossible to assert that of the present utility model being embodied as is confined to these explanations.For this utility model
For person of an ordinary skill in the technical field, make without departing from the concept of the premise utility
Some equivalents substitute or obvious modification, and performance or purposes are identical, all should be considered as belonging to this practicality new
The scope of patent protection that type is determined by the claims submitted to.
