Abstract
The invention relates to a bottom bed temperature control device for a fluidized bed for producing aluminum fluoride. The bottom bed temperature control device for the fluidized bed for producing aluminum fluoride comprises the fluidized bed, a fluidized bed hot air furnace and a combustion fan, wherein the fluidized bed hot air furnace is connected with the fluidized bed; the combustion fan is connected with the fluidized bed and the fluidized bed hot air furnace; the bottom bed temperature control device is characterized in that a bottom bed of the fluidized bed is externally provided with an air duct; and the air duct is connected with the combustion fan. According to the bottom bed temperature control device, the temperature of the fluidized bed is adjusted by interaction of inlet valves and outlet valves with a regulating valve; when the temperature is too high, the air duct can exert a cooling effect; the temperature control device is good in temperature control effect, low in cost and easy to realize; and an effect of prolonging service life is achieved by controlling the temperature of the fluidized bed.
Description
Technical field
The present invention relates to a kind of aluminum fluoride and produce fluidized-bed bottom temperature regulating device.
Background technology
Often can use fluidized-bed in the vent gas treatment process, but in certain some production process, owing to excess Temperature, the perishable situation of fluidized-bed rapid wear often can occur during particularly aluminum fluoride is produced.Greatly shorten work-ing life, increased operation cost.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of efficient high, and good heat dissipation, the aluminum fluoride of controllable temperature is produced fluidized-bed bottom temperature regulating device.
Aluminum fluoride provided by the present invention is produced fluidized-bed bottom temperature regulating device, comprise fluidized-bed, fluid bed heat wind furnace and burner blower, the fluid bed heat wind furnace connects fluidized-bed, burner blower is connected with the fluid bed heat wind furnace with fluidized-bed respectively, it is characterized in that, described fluidized-bed bottom is outside equipped with the air channel, and the air channel is connected with burner blower.
Described air channel is annular passage, and full weld is welded on around the bottom, and it has ventilation opening to be communicated with outside atmosphere.
Be disposed with variable valve and the first inlet valve on the connecting tube of air channel and burner blower, the first inlet valve is connected outside atmosphere with the connecting tube place of burner blower by the second inlet valve.
Burner blower connects the fluid bed heat wind furnace by the first outlet valve, and the first outlet valve is connected outside atmosphere with the connecting tube place of burner blower by the second outlet valve.The first inlet valve, the second inlet valve, the first outlet valve, the second outlet valve and the variable valve switch that cooperatively interacts is in order to reach the purpose of temperature adjustment.
The beneficial effect that the present invention has is, in order to adjust fluidized-bed temperature, cooling effect also can be played in the air channel when excess Temperature by the terminal valve that cooperatively interacts and variable valve.Temperature control is effective, and cost is low, is easy to realize.Reach the effect that increases the service life by the control fluidized-bed temperature.
Description of drawings
Fig. 1 is structural representation of the present invention;
Among the figure: 1, fluidized-bed; 2, bottom; 3, variable valve; 4, the first inlet valve; 5, the second inlet valve; 6, burner blower; 7, the first outlet valve; 8, the second outlet valve; 9, air channel; 10, fluid bed heat wind furnace.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described further:
Aluminum fluoride is as shown in Figure 1 produced fluidized-bed bottom temperature regulating device, comprise fluidized-bed 1, fluid bed heat wind furnace 10 and burner blower 6, fluid bed heat wind furnace 10 connects fluidized-bed 1, burner blower 6 is connected with the fluid bed heat wind furnace with fluidized-bed 1 respectively and is connected, the bottom 2 of fluidized-bed 1 is outside equipped with air channel 9, and air channel 9 also is connected with burner blower 6.
Air channel 9 is annular passage, and full weld is welded on around the bottom 2, and it has ventilation opening to be communicated with outside atmosphere.
Be disposed with variable valve 3 on the connecting tube of air channel 9 and burner blower 6 and the first inlet valve 4, the first inlet valves 4 are connected outside atmosphere with the connecting tube place of burner blower 6 by the second inlet valve 5.
Burner blower 6 connects fluid bed heat wind furnace 10, the first outlet valves 7 by the first outlet valve 7 and is connected outside atmosphere with the connecting tube place of burner blower 6 by the second outlet valve 8.
When driving heats up to fluidized-bed 1, close the second outlet valve 8 and first inlet valve 4 of burner blower 6, open the first outlet valve 7 and the second inlet valve 5, air sucks from the second inlet valve 5 like this, and hot blast is discharged from the first outlet valve 7 behind roasting kiln, and its normal convection bed 1 is heated up, when temperature is raised to prescribed value, can feed intake, with the carrying out of reaction liberated heat maintenance reaction, can stop burner blower 6 this moment; When finding fluidized-bed 1 bottom 2 excess Temperature in the startup procedure, can take to open burner blower 6 first inlet valves 4 and the second outlet valve 8, close simultaneously the second inlet valve 5 and the first outlet valve 4,9 ventilation opening sucks freezing air from the air channel like this, and by annular air channel, take away waste heat.Wherein, what of heat variable valve 3 can take out of according to temperature required adjusting of bottom, to guarantee the bottom complete reaction and not affect final product quality.
