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 cement rotary kiln surface heat reclaim unit, including outer housing 2, water collar
3, heat exchanger 5, air blower tube 4 and volume damper 6, water collar 3 and outer housing 2 are in regular hexagon, right
Claim to be arranged on outside the outer surface of cement rotary kiln 1, between two water collars 3, be provided with gap, and all with
There is gap between the outer surface of rotary kiln 1, between water collar 3 and rotary kiln 1 surface, form ventilating duct
7, water collar 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 and sender property outlet 9.Outer housing 2 is a closing case being wrapped in outside water collar 3,
Being provided with two cavitys in it, air blower tube 4 is connected with a cavity of outer housing 2 and is provided with air quantity in this cavity
Regulation valve 6, enters the air quantity in overcoat 2 with regulation by air blower tube 4.Heat exchanger 5 is arranged on outer housing
In another cavity of 2, the working medium in water collar 3 is by sender property outlet 9 and the working medium in heat exchanger 5
Can use connected in series or in parallel.Heat-insulation layer can be provided with, so that working medium is fully inhaled in overcoat 2 interior surface
The heat receiving cement rotary kiln 1 exchanges with external heat.It is big that water collar 3 both sides inwall is arranged at intervals with length
It is less than the first projection 10 of water collar 3 diameter in 1/2nd of water collar 3 diameter, makes water collar 3
Interior gap becomes multiple S-shaped, increases cold fluid working substance time of staying in water collar 3, fully absorbs water
The heat of mud rotary kiln 1.Water collar 3 has, near the outer wall of rotary kiln 1, the extended to rotary kiln 1
Two projections 11, the length of the second projection 11 between water collar 3 and rotary kiln 1 distance 1/4th to
Between 3/4ths so that cold flow body extended residence time in ventilating duct 7, fully absorb cement and return
The heat of rotary kiln 1.Owing to water collar 3 and outer housing 2 are in orthohexagonal geometry, enter inside and outside logical
The air in air channel forms whirlpool in the position of hexagon angle, enhances heat-transfer effect, extends air
The time of staying in air channel, increase the heat of recovery, improve 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 space between water collar 3 and rotary kiln 1, heated when flowing through rotary kiln 1 surface, inhale
Regaining the heat on rotary kiln 1 surface, the air after heating enters outside the pipe of tubular heat exchanger 5, heating row
Fluid in pipe in heat exchange of heat pipe 5, this fluid is from water collar 3, and heated tube fluid can be by
Collection utilization, thus saved the energy, reduce overall energy consumption.By working medium in regulation water collar 3
Flow and the aperture along the air blower tube 4 of cement rotary kiln 1 length layout realize rotary kiln 1 surface temperature
Step regulation, fully absorb 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
