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 fluid bed bottom temperature regulating device.
Background technology
In vent gas treatment process, often can use fluid bed, but in certain some production process, particularly aluminum fluoride produce in due to excess Temperature, often there will be the perishable situation of fluid bed rapid wear.Greatly shorten service 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 efficiency high, and good heat dissipation, the aluminum fluoride of controllable temperature is produced fluid bed bottom temperature regulating device.
Aluminum fluoride provided by the present invention is produced fluid bed bottom temperature regulating device, comprise fluid bed, fluid bed heat wind furnace and combustion fan, fluid bed heat wind furnace connects fluid bed, combustion fan is connected with fluid bed heat wind furnace with fluid bed respectively, it is characterized in that, described fluid bed bottom is outside equipped with air channel, and air channel is connected with combustion fan.
Described air channel is annular passage, and full weld is welded on around bottom, and it has ventilating opening to be communicated with external environment condition.
In the connecting pipe of air channel and combustion fan, be disposed with control valve and the first inlet valve, the first inlet valve is connected external environment condition with the connecting pipe place of combustion fan by the second inlet valve.
Combustion fan connects fluid bed heat wind furnace by the first outlet valve, and the first outlet valve is connected external environment condition with the connecting pipe place of combustion fan by the second outlet valve.The first inlet valve, the second inlet valve, the first outlet valve, the second outlet valve and the control valve switch that cooperatively interacts, in order to reach the object of temperature adjustment.
The beneficial effect that the present invention has is, by the terminal valve that cooperatively interacts and control valve, in order to adjust fluidized-bed temperature, when excess Temperature, cooling effect also can be played in air channel.Temperature control is effective, and cost is low, is easy to realize.By controlling fluidized-bed temperature, reach the effect increasing the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, fluid bed; 2, bottom; 3, control valve; 4, the first inlet valve; 5, the second inlet valve; 6, combustion fan; 7, the first outlet valve; 8, the second outlet valve; 9, air channel; 10, fluid bed heat wind furnace.
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described further:
Aluminum fluoride is as shown in Figure 1 produced fluid bed bottom temperature regulating device, comprise fluid bed 1, fluid bed heat wind furnace 10 and combustion fan 6, fluid bed heat wind furnace 10 connects fluid bed 1, combustion fan 6 is connected with fluid bed heat wind furnace 10 with fluid bed 1 respectively, the bottom 2 of fluid bed 1 is outside equipped with air channel 9, and air channel 9 is also connected with combustion fan 6.
Air channel 9 is annular passage, and full weld is welded on around bottom 2, and it has ventilating opening to be communicated with external environment condition.
In the connecting pipe of air channel 9 and combustion fan 6, be disposed with control valve 3 and the first inlet valve 4, the first inlet valves 4 are connected external environment condition with the connecting pipe place of combustion fan 6 by the second inlet valve 5.
Combustion fan 6 connects fluid bed heat wind furnace 10, the first outlet valves 7 by the first outlet valve 7 and by the second outlet valve 8, is connected external environment condition with the connecting pipe place of combustion fan 6.
When driving fluid bed 1 to heat up, close the second outlet valve 8 and first inlet valve 4 of combustion fan 6, open the first outlet valve 7 and the second inlet valve 5, air sucks from the second inlet valve 5 like this, and after combustion furnace, hot blast is discharged from the first outlet valve 7, and its normal convection bed 1 is heated up, when temperature is raised to setting, can feed intake, with reaction liberated heat, keep the carrying out of reaction, now can stop combustion fan 6; While finding fluid bed 1 bottom 2 excess Temperature in startup procedure, can take to open combustion fan 6 first inlet valves 4 and the second outlet valve 8, close the second inlet valve 5 and the first outlet valve 4 simultaneously, from air channel, 9 ventilating opening sucks cold air like this, and by annular air channel, take away waste heat.Wherein, control valve 3 can be according to the temperature required number of taking heat out of that regulates of bottom, to guarantee bottom complete reaction and not affect end product quality.
