Description
Technical field
The present invention designs technical field of dust removal equipment, specifically a kind of cleaning shaft spark blowout.
Background technique
In the cleaning shaft of the Industrial Stoves such as steel-smelting electric furnace, Fesi Furnace, brickkiln, since smoke catching one's intention as revealed in what one says amount is larger,
Often by the spark grain intake line of bulky grains some in kiln, in order to avoid these spark grains are in bag filter
Filter bag is caused to impact and be burnt, and influences deduster filter effect, and traditional approach is to install rotation additional between pipeline and bag filter
Wind deduster eliminates the spark in flue gas.But cyclone dust collectors are bulky, steel quantity consumption is more, and manufacturing cost is higher, for one
The problem of it is excessively high that a little small-sized kilns will cause dust pelletizing system investment, increases customer investment cost.
Summary of the invention
The object of the present invention is to provide a kind of cleaning shaft spark blowouts, and structure is simple, compact, and manufacture, installation are just
Victory, lower production costs can effectively eliminate the spark grain in cleaning shaft.
In order to achieve the above objectives, the technical solution used in the present invention are as follows:
A kind of cleaning shaft spark blowout, it includes the change that both ends are mounted among two sections of cleaning shafts by flange
Diameter pipe, the lumen diameter in the middle part of reducer pipe are greater than the internal diameter of cleaning shaft, and the side of flange is equipped with back-fire relief net, reducer pipe it is interior
Two groups of Spark catcher plates are installed, every group of Spark catcher plate is made of the plate that several piece is parallel to each other, plate and level in chamber
Angle between face is 25-45 °.
Preferably, the bottom wall of the reducer pipe is equipped with ash discharging hole.
Preferably, the junction of the flange is equipped with asbestos-packing gasket.
Preferably, the size of the online mesh aperture of the back-fire relief, be woven into back-fire relief net material thickness according to different
The partial size of spark grain is designed accordingly in discharge flue gas.
In use, when dust trapping device sucks flue gas in cleaning shaft, spark grain follows flue gas to the present invention
Enter in cleaning shaft together；The flue gas for being mingled with spark grain is installed in after the back-fire relief net refinement of flange side, into change
In diameter tube cavity, since pipe diameter becomes larger suddenly, the speed that flue gas is advanced can decline；Spark grain after reduction of speed continues to first
Group Spark catcher plate movement, after spark grain collides back-fire relief plate, the direction of motion of spark grain is changed, speed also sharply under
Drop, the spark grain being refined start to settle under gravity, be gathered near ash discharging hole；What another part did not settle
Spark grain continues to move ahead, and after encountering second group of Spark catcher plate, the direction of motion of spark grain is changed again, and speed is also again
It reduces, starts to settle under gravity, the spark grain being mingled in flue gas is largely all eliminated, and minority is not eliminated
Spark grain advance to back segment after the refinement of second layer back-fire relief net cleaning shaft in, granularity is broken down into very little, speed
It substantially reduces, impact to bag filter filter bag and the destruction burnt substantially eliminate.Use through the invention effectively extends
The service life of bag filter filter bag reduces the workload of maintenance personnel, reduces the operating cost in deduster later period.
The invention has the benefit that
(1) present invention installs reducer pipe among cleaning shaft, back-fire relief net is arranged at the both ends of reducer pipe, in reducer pipe
Two groups of Spark catcher plates are set in inner cavity, decomposes refinement spark grain twice using back-fire relief net, passes through the drop that becomes larger of variable diameter bore
The speed of service of low spark grain is changed the traffic direction and speed of spark grain by Spark catcher plate, eliminates spark grain to cloth
It the impact of bag dust collector filter bag and burns, effectively extends the service life of filter bag；
(2) present invention has the asbestos-packing gasket of high temperature resistance in the setting of the junction of flange, can enhance pipeline
Sealing performance prevents the leakage of flue dust；
(3) the configuration of the present invention is simple is compact, manufactures install convenient, production cost is low, is widely portable to all kinds of dedustings and sets
In standby.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
In figure: 1, flange, 2, back-fire relief net, 3, Spark catcher plate, 4, ash discharging hole, 5, reducer pipe, 6, asbestos-packing gasket, 7,
Plate.
Specific embodiment
The invention will now be described in further detail with reference to the accompanying drawings.
A kind of cleaning shaft spark blowout as shown in Figure 1, it, which includes both ends, is mounted on two sections of dedustings by flange 1
The lumen diameter of reducer pipe 5 among pipeline, 5 middle part of reducer pipe is greater than the internal diameter of cleaning shaft, and the side of flange 1 is equipped with resistance
The network of fire 2 is equipped with two groups of Spark catcher plates 3 in the inner cavity of reducer pipe 5, what every group of Spark catcher plate 3 was parallel to each other by several piece
Plate 7 is constituted, and the angle between plate 7 and horizontal plane is 25-45 °.The bottom wall of reducer pipe 5 is equipped with ash discharging hole 4.
The junction of flange 1 is equipped with asbestos-packing gasket 6.
The size of mesh aperture on back-fire relief net 2, be woven into back-fire relief net 2 material thickness according in different discharge flue gases
The partial size of spark grain is designed accordingly.
In use, when dust trapping device sucks flue gas in cleaning shaft, spark grain follows flue gas to the present invention
Enter in cleaning shaft together；The flue gas for being mingled with spark grain is installed in after the refinement of back-fire relief net 2 of 1 side of flange, is entered
In 5 inner cavity of reducer pipe, since pipe diameter becomes larger suddenly, the speed that flue gas is advanced can decline；Spark grain after reduction of speed continue to
First group of Spark catcher plate 3 moves, and after spark grain collides back-fire relief plate 7, the direction of motion of spark grain is changed, speed
Sharply decline, the spark grain being refined starts to settle under gravity, is gathered near ash discharging hole 4；Another part does not have
There is the spark grain of sedimentation to continue to move ahead, after encountering second group of Spark catcher plate 3, the direction of motion of spark grain is changed again,
Speed also reduces again, starts to settle under gravity；The spark grain being mingled in flue gas is largely all eliminated, a small number of
In the cleaning shaft that the spark grain not being eliminated advances to back segment after the refinement of second layer back-fire relief net 2, granularity is decomposed
To very little, speed is substantially reduced, and impact to bag filter filter bag and the destruction burnt substantially eliminate.Making through the invention
With the service life for effectively extending bag filter filter bag, the workload of maintenance personnel is reduced, reduces the deduster later period
Operating cost.
The configuration of the present invention is simple is compact, manufactures install convenient, production cost is low, is widely portable to all kinds of cleaners
In.
