Specific embodiment
The desiccation machine schematic diagram for utilizing cement kiln residual temperature as shown in Figure 1 mainly includes 2 two portions in desiccation room 1 and cement kiln
Point, if wherein desiccation firing chamber 1 is internally provided with arterial highway sludge transfer station 8, parallel to each other and horizontal peace between sludge transfer station 8
Dress.It is also provided with the air inlet entrance 3 entered for hot wind supply in the bottom of desiccation room 1, is additionally provided with row at the top of desiccation room 1
Air port 4, the effect of the exhaust outlet 4 are the gas discharge desiccation rooms 1 after drying sludge.Cement kiln 2 is also equipped with for heat supply
Distinguished and admirable hot-blast outlet 5 out and the air inlet 6 for air entrance.The air inlet entrance 3 and the hot wind of cement kiln 2 of desiccation room 1 go out
It is connected between mouth 5 by hot-blast main 7, one end of the hot-blast main 7 by hot-blast outlet 5 and is deep into cement kiln 2, hot wind
General pipeline 7 is in contact in the inside of cement kiln 2 with cooling zone 10, and the hot wind for flowing through hot-blast main 7 band 10 that is cooled is cooled down.
In order to reinforce cooling effect, hot-blast main 7 can be installed with S type, in order to increase the contact surface of cooling zone 10 Yu hot-blast main 7
Product.In the present embodiment, in order to express conveniently, a part of hot-blast main 7 is mounted on cement by the way of straight line stringing
In kiln 2.Under normal conditions, cement in the last process of calcining together (i.e. the process of calcined by rotary kiln) temperature can reach
It is 1000-1400 degrees Celsius, still very high even across the temperature of cooling processing, although this temperature is for dewatered sludge
The temperature that can be used, it is contemplated that may have a adverse impact to working environment during hot wind transmission (such as height
Influence of the temperature to nonrefractory equipment), so temperature is suitably cooled down again by cooling zone 10.
Hot blast manifold 9 is also connected on hot-blast main 7, the entrance of hot blast manifold 9 is located at air inlet entrance 3 and hot-blast outlet
Between 5, the air outlet of the hot blast manifold 9 is connected to from the side height echelon of desiccation room 1 with desiccation room 1, better in order to reach
Desiccation effect, the air outlet of hot blast manifold 9 are preferably located between neighbouring sludge transfer station 8.
The ventilation blower 11 of connection frequency converter 14, the ventilation blower are additionally provided with close to one end of hot-blast outlet 5 in hot-blast main 7
There are two 11 effects: one is improving gas pressure by the mechanical energy of input and supplying gas side by side body；The second is passing through frequency converter
The power of 14 control ventilation blowers 11 is to achieve the purpose that control the hot wind flow velocity in hot-blast main 7.
It is connect by air-exhausting duct with air inlet 6 in exhaust outlet 4, is being additionally provided with waste discharge mouth 12 at exhaust outlet 4, the row
The effect of useless mouth 12 is that the gas containing flying dust is discharged into atmosphere, prevents the gas from generating undesirable shadow to the production of cement
It rings.In order to achieve the purpose that be vented body, exhaust fan can be installed at waste discharge mouth 12.After gas is emitted, cement kiln 2
It is likely to occur the situation of cold wind deficiency, can be entered so that supplement wind is arranged on the air-exhausting duct between exhaust outlet 4 and air inlet 6 this when
Mouth 13, the position of the close air inlet 6 of the supplement wind entrance 13.
The above is a kind of structure of desiccation machine using cement kiln residual temperature, for the first time in use, filling in cement kiln 2
Full air, in cement kiln 2 after calcining, the cement of high temperature is stored in cooling zone 10 and nearby radiates cement, cement it is remaining
Temperature heats the air in cement kiln 2, and hot wind flows to desiccation room 1 by hot-blast main's 7, is mounted on the upper of hot-blast main 7
Ventilation blower 11 can control the flow velocity that hot wind goes out, and guaranteeing not only will not be too fast when hot wind passes through desiccation room 1, but also will not be excessively slow.Heat
Distinguished and admirable to will lead to flying dust floating in desiccation room 1 through desiccation room 1 is too fast, hot wind, which flows through desiccation room 1, can make desiccation degree not slowly excessively
Enough, efficiency is too low.Hot wind has two approach when passing through hot-blast main 7, one is by hot blast manifold 9 into desiccation room 1, secondly
It is that desiccation room 1, the cooperation of two kinds of routes of entry, so that the drying efficiency in desiccation room 1 significantly mentions are entered by air inlet entrance 3
It is high.The gas for flowing through sludge transfer station 8 flows out desiccation room 1 by exhaust outlet 4, flows into cement kiln 2, realize following for gas
Circulation is dynamic.
The above is the utility model preferred embodiment, is not constituted to scope of protection of the utility model
Limitation.
