Abstract
A kind of rotary kiln cooler baking kiln system includes the negative-pressure air fan (6) for being carried out feeding chute (3), the dust-laden steam for being connected to cooler upper rear and the heat smoke conveyance conduit (5) of the rotary kiln (1) for drying kiln heating, the cooler (4) being set to below rotary kiln, connection rotary kiln and cooler using natural gas and being installed on dust-laden steam and heat smoke conveyance conduit.The utility model can effectively reduce production cost, reduce security risk, improve cooler liner service life.
Description
Technical field
The liner that the utility model belongs to rotary kiln cooler repairs the baking kiln system technical field after pouring again.
Background technology
Rotary kiln is common smelting equipment in aluminium production, to be dried to rotary kiln and its cooler before igniting produces
Kiln.The baking kiln of rotary kiln cooler is used in the industry at present and adds interim burner on cooler head, the note in cooler
Enter the mode that fuel dry kiln.There are following drawbacks for such way：(1) installation operation is inconvenient, needs specially to build combustion
Expects pipe road and burner, and have certain security risk；(2) fuel consumption is big, and combustion is used except rotary kiln, after-burner dry kiln
Material is outer, should also additionally increase fuel and carry out baking kiln to cooler；(3) heating rate inconvenience controls, and need to arrive Field adjustment fuel use
Amount, to control heating rate；(4) uneven heating, and feeding chute part is not easy to toast.
Invention content
Purpose of the utility model is to solve problem of the existing technology, it one kind is provided can effectively reduce and be produced into
Originally the rotary kiln cooler baking kiln system for, reducing security risk, improving cooler liner service life.
The purpose of this utility model is achieved through the following technical solutions.
A kind of rotary kiln cooler baking kiln system includes carrying out drying the rotary kiln of kiln heating using natural gas, being set to back
The feeding chute of cooler, connection rotary kiln and cooler below rotary kiln, the dust-laden steam for being connected to cooler upper rear
With heat smoke conveyance conduit and the negative-pressure air fan being installed on dust-laden steam and heat smoke conveyance conduit.
The use of the utility model makes rotary kiln cooler dry kiln heating and is provided with following characteristics：(1) safe operation letter
Just, negative-pressure air fan throttle opening and frequency only need to be controlled, without increasing other ancillary equipments；(2) fuel, rotary kiln are saved
The heat that fuel generates can carry out baking kiln to rotary kiln and cooler liner simultaneously；(3) heating rate is convenient for control, according to cold
But machine heating curve adjusts rotary kiln natural gas dosage and the i.e. controllable heating rate of cooler outlet negative pressure；(4) each portion of liner
Position is heated evenly, and the method mainly heats liner by thermal current, the opposite flame direct baking liter of thermal current heating
More preferably, and airflow direction is rotary kiln end to cooler kiln tail to temp effect, while drying kiln to cooler, in feeding chute
Lining is heated compared with cooler more fully.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Rotary kiln cooler as shown in Figure 1 dries kiln system, include using natural gas 2 dry kiln heating rotary kiln 1,
It is set to the cooler 4 below rotary kiln, the feeding chute 3 for connecting rotary kiln and cooler, is connected to cooler upper rear
Dust-laden steam and heat smoke conveyance conduit 5 and the negative-pressure air fan 6 that is installed on dust-laden steam and heat smoke conveyance conduit.
The utility model heats cooler 4 using the heat that rotary kiln natural gas 2 generates, and passes through negative-pressure air fan 6
Draft is generated, the part thermal current in rotary kiln is pumped into cooler, hot gas flows through feeding chute 3, cooler head and tail
Portion enters dust-laden steam and heat smoke conveyance conduit 5 is drained, and negative-pressure air fan persistently generates draft, and thermal current is constantly flowing,
During flowing, i.e., heat temperature raising is carried out to cooler, and can be controlled by the frequency and throttle opening of negative-pressure air fan
By the size of cooler heat, to control rate of warming, ensures that cooler heats up by heating curve, improve and dry kiln matter
Amount.
Using the utility model, the heat generated using combustion of natural gas in rotary kiln repairs cooler again to be poured
Rear liner carries out heat temperature raising, in addition need not specially build fuel conduit and burner, and simultaneously to feeding chute into
Row baking, and the rate heated can be controlled to adjust by exhaust gas fan, heat temperature raising is uniform, and it is good to dry kiln effect.
