It is up to 20% with the total content of water, molybdenum concentrate drying is the process of a de-oiling, dehydration, this part oil and water are in drying equipment
Middle volatilization, reaches drying effect, and tail gas is directly discharged from chimney.
But containing a large amount of excessive fuel consumptions in the tail gas of drying equipment discharge, these recyclable excessive fuel consumptions are directly discharged in atmosphere,
It wastes, also pollution environment.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of molybdenum concentrate drying and flue gas recovery system, the systems
Kerosene and diesel oil in recyclable dry flue gas mitigate the dry flue gas peculiar smell of molybdenum concentrate, reduce dirt of the flue gas to environment
Dye.
The utility model is realized in this way:
A kind of molybdenum concentrate is dry and flue gas recovery system, including drying machine and burner, drying machine pass through with burner
Pipeline is connected, and is characterized in that the waste gas outlet of the drying machine is connected to bagroom, the gas of bagroom
Body outlet is connected with pipe bundle condenser tube side, and the gas outlet of the pipe bundle condenser tube side connects blower；The tubulation condensation
Connect condensate water pot between the condensing water inlet and condensation-water drain of device shell side, pipe bundle condenser shell side condensing water inlet with
Pipeline between the water outlet of condensate water pot is equipped with centrifugal pump；Water-oil separating is connected in the bottom leakage fluid dram of pipe bundle condenser
Device.
Further, the feed inlet of the burner connects self-conveyor feed, and the wet molybdenum concentrate for oil-containing water is sent into
Drying machine.
Further, the top of pipe bundle condenser is arranged in the gas outlet of the pipe bundle condenser, close to gas outlet
Position is equipped with manhole.
Further, pipe bundle condenser close to gas outlet lower section be equipped with degreasing unit, prevent condensed grease into
Enter pipe bundle condenser outlet conduit.
Further, the degreasing unit is demister or demister.
The beneficial effects of the present invention are:
(1) hot wind of drier is sent into using burner, dry to the molybdenum concentrate after flotation, the You Heshui in molybdenum concentrate is waved
Hair enters hot-air, and after bagroom gathers dust, pipe bundle condenser separates the grease in flue gas from hot wind, then arranges
Tail gas is put, a large amount of kerosene and diesel oil, the kerosene for including in tail gas and the decline of diesel oil concentration can be recycled, mitigates the dry tail of molybdenum concentrate
Gas peculiar smell；
(2) kerosene and diesel fuel mixtures i.e. waste oil that oil water separator is separated, calorific value is very high, can be recycled
It utilizes, again flotation molybdenum concentrate, fuel purchases can be reduced directly as fuel, can also be used as byproduct sale, create one
Fixed economic value.

Specific embodiment
As shown, molybdenum concentrate drying and flue gas recovery system, including drying machine 3 and burner 1, the drying machine
3 feed inlet is connected with self-conveyor feed 2, for the wet molybdenum concentrate of oil-containing water to be sent into drying machine 3；Drying machine 3 and burning
Device 1 is connected by pipeline, and the waste gas outlet of the drying machine 3 is connected with bagroom 4, the gas of bagroom 4
Outlet is connected with 5 tube side of pipe bundle condenser；The pipe bundle condenser 5 includes shell, and the demister on top inside the shell is arranged
507, it is equipped with condensation-water drain 501, condensing water inlet 502, leakage fluid dram 503, air inlet 504, gas outlet 505, people on the shell
The top of shell is arranged in hole 506, the gas outlet 505, and manhole 506 is located at close to the position of gas outlet 505, demister 507
The lower position of corresponding gas outlet 505, exhaust gas enter 5 tube side of pipe bundle condenser by air inlet 504, are discharged through gas outlet 505,
The gas outlet 505 connects blower 6 by pipeline, prevents condensed grease from entering 5 outlet conduit of pipe bundle condenser.Condensed water
Outlet 501 and condensing water inlet 502 communicated with 5 shell side of pipe bundle condenser and condensation-water drain 501 and condensing water inlet 502 it
Between condensate water pot 7 connected by external pipe, in the condensing water inlet 502 and condensate water pot 7 of pipe bundle condenser 5 tubulation shell side
External pipe and the setting centrifugal pump 8 on the external pipe between water outlet；In the bottom leakage fluid dram 503 of pipe bundle condenser 5
Connect oil water separator 9.
When work, 200 DEG C or more of the hot wind (hot-air) generated in burner 1 enters drying machine 3, spiral by pipeline
The wet molybdenum concentrate of oil-containing water is sent into drying machine 3 by charger 2, and in drying machine 3, molybdenum concentrate and hot wind are sufficiently mixed, molybdenum essence
After mine absorbs the heat of hot-air, oil and water volatilization in molybdenum concentrate are mixed into hot-air, contain waste oil and water and molybdenum concentrate dust
Hot-air (flue gas) enter bagroom 4, be filtered out through 4 molybdenum concentrate dust of bagroom, bagroom 4
The remaining hot exhaust gas containing waste oil and water is exported to be discharged under the twitch of blower 6 into pipe bundle condenser 5.
Tube side walks the hot exhaust gas of oil-containing and water in pipe bundle condenser 5, and shell side is leaked water, and the temperature of water is well below hot exhaust gas
Temperature is precipitated after the grease condensation in tail gas, is flowed out by bottom leakage fluid dram 503, into oil water separator 9.Oil water separator 9
It is different with the density of water using oil, grease natural layering separates oil and water.
Since hot exhaust gas temperature is much higher than coolant-temperature gage, condensate water pot 7 is set, and by the ringing of centrifugal pump 8, tubulation is cold
Water in condenser 5 constantly enters from condensing water inlet 502, enters condensate water pot 7 after the discharge of condensation-water drain 501, completes cold
But.
