Abstract
The utility model discloses a kind of bag filter of high temperature reduction kiln, including dust cleaning case, ash bucket, support frame, blast pipe and discharge pipe, and the dust cleaning case includes purification gas chamber, the dirt pocket at middle part and the inlet plenum of lower part on top；Filter chamber equipped with multiple built-in filter bags in the dirt pocket, one end of the inlet plenum are connected to blast pipe, and equipped with multiple wind-distributing pipes that axis direction and airintake direction are vertical in inlet plenum, the wind-distributing pipe is evenly distributed；The lower end of the filter chamber of the blast pipe side is concordant with the upper limb of blast pipe nozzle.The filter bag senile abrasion speed of the utility model is slower, and service life is longer, and maintenance workload is small, high dust collection efficiency.
Description
Technical field
The utility model relates to technical field of dust removal equipment, the bag filter of specifically a kind of high temperature reduction kiln.
Background technique
Bag filter is one kind of cleaner, is widely used in the fields such as mine, metallurgy, building materials, machinery, chemical industry,
Have the characteristics that high dust collection efficiency, processing air quantity range is wide, structure is simple, attended operation is convenient, low cost, its working principle is that
Gas containing dust enters in bag filter, and the filter bag in bag filter is filtered dust, and dust is blocked in
Filter bag surface, it is outer to achieve the purpose that dust removal by filtration that clean gas then penetrates filter bag discharge deduster.Although bag filter
Application is big, but in some environments use when also can be defective, such as apply in high temperature reduction kiln when gathering dust, due to gathering dust
Gas temperature is high, and inlet gas velocities are big, and filter bag aging is caused to accelerate, and shakes larger, hits friction, accelerate filter bag abrasion to
It shortens the working life, maintenance workload is big.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of filter bag senile abrasion speed is slower, service life
Longer, maintenance workload is small, the bag filter of the high temperature reduction kiln of high dust collection efficiency.
The technical scheme adopted by the utility model is providing the bag filter of high temperature reduction kiln, including dust cleaning case, ash
Bucket, support frame, blast pipe and discharge pipe, the dust cleaning case include the purification gas chamber on top, the dirt pocket at middle part and lower part
Inlet plenum；Filter chamber equipped with multiple built-in filter bags in the dirt pocket, one end of the inlet plenum are connected to blast pipe, into
Equipped with multiple wind-distributing pipes that axis direction and airintake direction are vertical in gas chamber, the wind-distributing pipe is evenly distributed；The blast pipe
The lower end of the filter chamber of side is concordant with the upper limb of blast pipe nozzle.
Preferably, the blast pipe be equipped with adjustable cold blast sliding valve, adjusted by the control of cold blast sliding valve cold wind into
Enter amount and then to control the temperature of air inlet, it is ensured that filter bag can within the scope of normal temperature normal use, extend the cloth bag service life, subtract
Few maintenance cost, reduces production cost.
After using the above structure, the utility model bag filter is lowered by the way that wind-distributing pipe is arranged in inlet plenum
The flow velocity of gas is evenly distributed to corresponding filter chamber, improves efficiency of dust collection, filter chamber lower end and blast pipe pipe in inlet side
Mouthful upper limb concordantly avoid flue gas it is excessive impact caused by filter bag undue wear, extend service life, maintenance
It is reduced.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the bag filter of the prior art.
Fig. 2 is the structural schematic diagram of the utility model bag filter.
In figure, 1, dust cleaning case, 2, blast pipe, 3, adjustable cold blast sliding valve, 4, wind-distributing pipe, 5, ash bucket, 6, support frame, 7, outlet air
Pipe.
Specific embodiment
The utility model is described in detail below in conjunction with drawings and examples.
As shown in Fig. 2, the bag filter of the utility model high temperature reduction kiln, including dust cleaning case 1, ash bucket 5, support frame 6,
Blast pipe 2 and discharge pipe 7, dust cleaning case 1 include purification gas chamber, the dirt pocket at middle part and the inlet plenum of lower part on top；Purified gas
It is connected to discharge pipe 7, blast pipe 2 and discharge pipe 7 are respectively provided at 1 two sides of dust cleaning case, and multiple built-in filter bags are equipped in dirt pocket
Filter chamber, filter chamber are arranged along 2 side of blast pipe to 7 side of discharge pipe, and one end of inlet plenum is connected to blast pipe 2, sets in inlet plenum
There are the multiple wind-distributing pipes 4 of axis direction and airintake direction vertically, the both ends of each wind-distributing pipe 4 are connected on the inner wall of inlet plenum,
Wind-distributing pipe 4 is evenly distributed to 7 side of discharge pipe along 2 side of blast pipe；The lower end of the filter chamber of 2 side of blast pipe and blast pipe 2 are managed
The upper limb of mouth is concordant.
In the specific implementation, blast pipe 2 is equipped with adjustable cold blast sliding valve 3 to the utility model, for passing through control valve
Aperture regulation intake is to control the temperature of air inlet.
The utility model reduces the flow velocity of air inlet, so that air quantity is in each mistake by the way that wind-distributing pipe is arranged in inlet plenum
The difference of filter chamber is more uniform, improves the efficiency of dedusting, and cold blast sliding valve is arranged, reduces the temperature of air inlet, avoids high temperature pair
The influence of filter bag, the setting of the filter chamber of blast pipe side also avoid entering the wind direct impact, reduce the abrasion of filter bag, extend
Service life reduces maintenance workload.
