Abstract
The invention discloses a spark eliminator for dust collection pipelines, comprising a reducing pipe having two ends mounted in the middle of two dust collection pipelines through flanges; the inner diameter of a middle cavity of the reducing pipe is greater than that of the dust collection pipelines, one side of each flange is provided with a fire retardant mesh, two groups of spark trap plates are mounted in the inner cavity of the reducing pipe, and each group of spark trap plates includes a plurality of parallel plates which are 25-45 degrees angled to the horizontal plane. Spark particles are decomposed twice and refined by using the fire retardant meshes, running speed of the spark particles is decreased through the increase in the inner diameter of the reducing pipe, the running direction and speed of the spark particles are changed through the spark trap plates, impact and burn of filter bags of bag dust collectors due to the spark particles are eliminated, and the service lives of the filter bags are effectively prolonged. The spark eliminator is simple and compact in structure, convenient to manufacture and mount, low in production cost and widely applicable to various dust collectors.
Description
Technical field
The present invention designs technical field of dust removal equipment, specifically a kind of cleaning shaft spark blowout.
Background technology
In the cleaning shaft of the Industrial Stoves such as steel-smelting electric furnace, Fesi Furnace, brickkiln, because smoke catching one's intention as revealed in what one says amount is larger,
Often by some oarse-grained spark grain intake lines in kiln, in order to avoid these spark grains are in sack cleaner
Filter bag impacts and burns, and affects cleaner unit filter effect, traditional approach is to install rotation between pipeline and sack cleaner additional
Wind cleaner unit, the spark in flue gas is eliminated.But cyclone dust extractor is bulky, steel quantity consumption is many, and manufacturing cost is higher, for one
Small-sized kiln can cause dust pelletizing system investment too high a bit, increases the problem of customer investment cost.
Content of the invention
It is an object of the invention to provide a kind of cleaning shaft spark blowout, structure is simple, compact, manufactures, installs just
Victory, production cost is relatively low, can effectively eliminate the spark grain in cleaning shaft.
For reaching above-mentioned purpose, the technical solution used in the present invention is：
A kind of cleaning shaft spark blowout, it is included two ends and is arranged on the reducing in the middle of two sections of cleaning shafts by flange
Pipe, the lumen diameter in the middle part of reducer pipe is more than the internal diameter of cleaning shaft, and the side of flange is provided with back-fire relief net, the inner chamber of reducer pipe
In two groups of Spark catcher plates are installed, every group of Spark catcher plate is constituted by the plate that several piece is parallel to each other, plate and horizontal plane
Between angle be 25-45 °.
Preferably, the diapire of described reducer pipe is provided with ash discharging hole.
Preferably, the junction of described flange is provided with asbestos-packing gasket.
Preferably, the size of the online mesh aperture of described back-fire relief, be woven into back-fire relief net material thickness according to different
In discharge flue gas, the particle diameter 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
Together enter in cleaning shaft；Be mingled with spark grain flue gas be installed in flange side back-fire relief net refinement after, enter become
In the tube cavity of footpath, because pipe diameter becomes suddenly big, the speed that flue gas is advanced can decline；Spark grain after reduction of speed continues to first
Group Spark catcher plate motion, after spark grain collides back-fire relief plate, the direction of motion of spark grain is changed, speed also drastically under
Fall, the spark grain being refined starts to settle under gravity, is gathered near ash discharging hole；Another part does 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
Reduce, start under gravity to settle, the spark grain major part being mingled with flue gas is 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
Substantially reduce, the impact to sack cleaner filter bag and the destruction burnt substantially eliminate.Extended using effective by the present invention
The service life of sack cleaner filter bag, reduces the workload of attendant, reduces the operating cost in cleaner unit later stage.
Beneficial effects of the present invention are：
（1）The present invention installs reducer pipe in the middle of cleaning shaft, arranges back-fire relief net at the two ends of reducer pipe, in the inner chamber of reducer pipe
Two groups of Spark catcher plates of middle setting, decompose refinement spark grain twice using back-fire relief net, reduce greatly fire by the change of reducing bore
The speed of service of flower grain, is changed traffic direction and the speed of spark grain, eliminates spark grain and cloth bag is removed by Spark catcher plate
The impact of dirt device filter bag and burning, effectively extends the service life of filter bag；
（2）The present invention has the asbestos-packing gasket of resistance to elevated temperatures in the setting of the junction of flange, can strengthen the sealing of pipeline
Performance, prevents the leakage of flue dust；
（3）Present configuration is simply compact, manufactures install convenient, low production cost, is widely portable in all kinds of cleaners.

Specific embodiment
The present invention is further detailed explanation below in conjunction with the accompanying drawings.
A kind of cleaning shaft spark blowout as shown in Figure 1, it includes two ends and is arranged on two sections of dedustings by flange 1
Reducer pipe 5 in the middle of pipeline, the lumen diameter at reducer pipe 5 middle part is more than the internal diameter of cleaning shaft, and the side of flange 1 is provided with resistance
The network of fire 2, is provided with two groups of Spark catcher plates 3 in the inner chamber of reducer pipe 5, every group of Spark catcher plate 3 is parallel to each other by several piece
Plate 7 is constituted, and the angle between plate 7 and horizontal plane is 25-45 °.The diapire of reducer pipe 5 is provided with ash discharging hole 4.
The junction of flange 1 is provided 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 particle diameter 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
Together enter in cleaning shaft；Be mingled with spark grain flue gas be installed in flange 1 side back-fire relief net 2 refinement after, enter
In reducer pipe 5 inner chamber, because pipe diameter becomes suddenly big, 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
Drastically decline, the spark grain being refined starts to settle under gravity, is gathered near ash discharging hole 4；Another part does not have
The spark grain having sedimentation continues to move ahead, and after encountering second group of Spark catcher plate 3, the direction of motion of spark grain is changed again,
Speed also reduces again, starts under gravity to settle；The spark grain major part being mingled with flue gas is all eliminated, minority
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 substantially reduces, and the impact to sack cleaner filter bag and the destruction burnt substantially eliminate.Making by the present invention
With effectively extending the service life of sack cleaner filter bag, reduce the workload of attendant, reduce the cleaner unit later stage
Operating cost.
Present configuration is simply compact, manufactures install convenient, low production cost, is widely portable to all kinds of cleaners
