Abstract
The utility model provides a device for removing coal dust deposited in a flue of a fluidized bed boiler. The device comprises a blower, wherein the air blower is connected with at least a blowpipe; two ends of the blowpipe are sealed; multiple blowholes are machined on the sidewall of the blowpipe; and the blowpipe is made of stainless steel. As an externally arranged blower for blowing and cleaning pipelines is utilized, the a device for removing coal dust deposited in the flue of the fluidized bed boiler, disclosed by the utility model, has the advantages of solving the difficulty of cleaning deposit sediments in the blowpipe and the flue, cleaning while producing, efficiently improving running rate of a production device, increasing capacity of the production device and also reducing safety risk in the cleaning process.
Description
Technical field
The utility model belongs to flue cleaning equipment manufacturing technology field, relates to a kind of device of removing fluidized bed furnace flue deposition coal dust.
Background technology
As everyone knows; Burning coal carries out the stove of heat supply; No matter how the structure of flue designs, and the flue dust that burning produces all can have dust precipitation in flue during through flue, influences the hot blast flux of flue; Cause consume to rise, heat utilization efficiency descends, even cause flue to stop up and then be forced to stop production.Especially the flue of the long fluidized bed furnace of pipeline, the sedimentation of its coal dust is more serious.Be through labor cleaning's flue at present mostly, temperature fall time is long, the unusual difficulty of cleaning, dangerous big, causes very big influence to production.
The utility model content
In order to overcome the problem that exists in the above-mentioned prior art, the purpose of the utility model provides a kind of device of removing fluidized bed furnace flue deposition coal dust, and need not cooling can clear up flue, less to the influence of producing.
For realizing above-mentioned purpose; The technical scheme that the utility model adopted is: a kind of device of removing fluidized bed furnace flue deposition coal dust, comprise hair-dryer, and hair-dryer is connected with at least one blower; The closed at both ends of blower is processed with a plurality of blowhole on the sidewall of blower.
Blower adopts stainless steel to process.
The utility model device blows afloat the deposition coal dust in the flue through blower, and the deposition coal dust sucking-off that will blow afloat through the air draft blower fan that links to each other with the fluidized bed furnace outlet conduit is again discharged after washing; Can guarantee the ordinary production of process units, can clean flues again, effectively ensure the normal operation of device, reduce the security risk in the scale removal process.
Description of drawings
Fig. 1 is the structural representation of the utility model device.
Fig. 2 is the user mode figure of the utility model device.
Among the figure: 1. blower, 2. blowhole, 3. hair-dryer, 4. hair-dryer air outlet, 5. burner hearth, 6. flue.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
In order to solve the problem that the deposition coal dust is difficult to clear up in the fluidized bed furnace flue; The utility model provides a kind of structure scavenge unit as shown in Figure 1; This scavenge unit comprises hair-dryer 3; The hair-dryer air outlet 4 of hair-dryer 3 is connected with at least one blower 1 respectively through airduct, and the closed at both ends of blower 1 is processed with a plurality of blowhole 2 on the sidewall of blower 1.
The utility model scavenge unit utilizes external blower fan blowing clearing of pipeline, has solved the difficult problem of deposit cleaning in airduct, the flue, can the cleaning of production limit, limit, effectively improved process units running rate, promoted the production capacity of process units; Also reduced the security risk in the scale removal process simultaneously.
For example; 9 meters of the flue length of a kind of Diammonium phosphate (DAP) (180,000 tons of DAP/) process units, 1.6 meters of flue diameters, the dust height in per two first quarter moon flues just reach the half the of flue diameter; Need once thoroughly clear up; Clearance time needs 3 days at least, has had a strong impact on ordinary production, and the cleaning difficulty greatly, the security risk in the scale removal process is quite big.After adopting the utility model scavenge unit; Adopt intermittent blowing (blowing in per 2 hours once in above-mentioned this device of production), can effectively coal dust be blown afloat and get rid of, prevented the deposition of coal dust in flue; To this process units heat energy is provided to greatest extent, does not influence ordinary production.
This scavenge unit is applicable to sedimental self-cleaning in the air channel of all kinds of flues that utilize hot-blast stove to carry out heat supply and all kinds of not easy to clean.
Claims (2)
1. remove the device that the fluidized bed furnace flue deposits coal dust for one kind; It is characterized in that, comprise hair-dryer (3), hair-dryer (3) is connected with at least one blower (1); The closed at both ends of blower (1) is processed with a plurality of blowhole (2) on the sidewall of blower (1).
