Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment, in particular to a bag type filtering device for tail gas treatment. Background Art

[0002] A bag filter is a device that filters out fine and dry dust in gas to obtain clean gas. Usually, the bag filter uses filter bags to filter dust. After the dust in the filter bags accumulates to a certain extent, the pulse system is used to flush down the dust. Currently, when the existing bag type filtering device is in use, it is necessary for workers to regularly clean or replace the filter bags. To disassemble and install the filter bags, the filter bags need to be taken out of the filtering device, which is likely to contaminate the workers' clothing. The taking-out process is relatively complex, increasing the time for replacing the filter bags, and thus reducing the working efficiency of the bag type filtering device.

[0003] For example, the utility model patent with the publication number CN209771623U discloses a bag filter with multi-layer filtration, including a first filter main body. The lower end of the first filter main body is fixedly connected with a dust outlet one. The side end of the first filter main body is fixedly connected with an air inlet. A fixing member one is fixedly connected to the inner wall of the first filter main body. A connecting member is movably connected inside the fixing member one. One end of the connecting member is fixedly connected with a baffle plate. One end of the baffle plate is fixedly connected with a cloth bag. A rotary door one is fixedly connected to the outer wall of the first filter main body. When this device is in use, it is necessary for workers to regularly clean or replace the filter bags. To disassemble and install the filter bags, the filter bags need to be taken out of the filtering device, which is likely to contaminate the workers' clothing. The taking-out process is relatively complex, increasing the time for replacing the filter bags, and thus reducing the working efficiency of the bag type filtering device.

The filtering block 16 is slidably installed inside the sliding grooves 10 through the sliding blocks 21, which can conveniently move the filtering block 16 outside the tower body 1, facilitating the staff to replace the filter bag 18 and avoiding the stains inside the first filtering chamber 11 from contaminating the staff's clothing;

[0024] The filter bag 18 is inserted into the installation groove 22 through the installation block 15. Adopting the insertion installation method facilitates the staff to replace the filter bag 18, reduces the time for replacing the filter bag 18, and thus improves the working efficiency of the bag-type filtering device.

[0025] In this embodiment, it is further set that a second filtering chamber 19 is arranged inside the tower body 1 and above the first filtering chamber 11. An air filter 14 is fixedly installed inside the second filtering chamber 19. A first protective door 6 is hinged on the tower body 1 at the position of the second filtering chamber 19. A pair of first fixing blocks 2 are arranged on the first protective door 6. A first bolt 23 is respectively screwed on the pair of first fixing blocks 2. A pair of first threaded holes 25 are arranged on the tower body 1. The first fixing blocks 2 are fixedly installed inside the first threaded holes 25 through the first bolts 23. A first baffle 8 is arranged inside the second filtering chamber 19. A second sealing strip 13 is arranged on the first protective door 6. The second sealing strip 13 is movably arranged on the first baffle 8;

[0026] The second filtering chamber 19 is a pretreatment chamber. The air filter 14 can filter the large molecular particles in the tail gas, reducing the load on the bag-type filtering device and thus prolonging the service life of the filter bag 18;

[0027] The first fixing blocks 2 are fixedly installed inside the first threaded holes 25 through the first bolts 23, thereby fixing the first protective door 6 on the first baffle 8. The first protective door 6 is sealed by the second sealing strip 13, which can avoid the situation that the tail gas inside the second filtering chamber 19 moves outside the tower body 1 and pollutes the surrounding air.

[0028] In this embodiment, it is further set that a second protective door 7 is hinged on the tower body 1 at the position of the first filter bin 11. A pair of second fixing blocks 3 are arranged on the second protective door 7. Second bolts 24 are respectively screwed on the pair of second fixing blocks 3. A pair of second threaded holes 26 are arranged on the tower body 1. The second fixing blocks 3 are fixedly installed in the second threaded holes 26 through the second bolts 24. A second baffle 9 is arranged in the first filter bin 11. A first sealing strip 12 is arranged on the second protective door 7. The first sealing strip 12 is movably arranged on the second baffle 9;

[0029] The second fixing blocks 3 are fixedly installed in the second threaded holes 26 through the second bolts 24, so that the second protective door 7 is fixed to the second baffle 9. The second protective door 7 is sealed by the first sealing strip 12, which can prevent the tail gas in the first filter bin 11 from moving outside the tower body 1 and polluting the surrounding air.

[0030] In this embodiment, it is further set that an exhaust bin 17 is arranged in the tower body 1 below the first filter bin 11. An exhaust pipe 4 is arranged on the tower body 1. The exhaust pipe 4 is connected to the exhaust bin 17.

[0031] In this embodiment, it is further set that an intake pipe 5 is arranged on the tower body 1. The intake pipe 5 is connected to the second filter bin 19.

[0032] In this embodiment, it is further set that a handle 20 is arranged on the side wall of the filter block 16.

[0033] Example: When the bag filter is in use, the tail gas enters the second filter chamber 19 through the intake pipe 5. The second filter chamber 19 is a pretreatment chamber. The air filter 14 can filter the large molecular particles in the tail gas, reducing the load on the bag filter and thus extending the service life of the filter bag 18. The pretreated tail gas enters the exhaust chamber 17 after passing through the filter bag 18 and is then discharged to a designated location through the exhaust pipe 4. The first fixing block 2 is fixedly installed in the first threaded hole 25 through the first bolt 23, thereby fixing the first protective door 6 on the first baffle 8. The first protective door 6 is sealed by the second sealing strip 13, which can prevent the tail gas in the second filter chamber 19 from moving outside the tower body 1 and polluting the surrounding air. At the same time, it is convenient for the staff to open the first protective door 6 and perform single-item maintenance on the air filter 14, improving the maintenance efficiency of the bag filter equipment. The second fixing block 3 is fixedly installed in the second threaded hole 26 through the second bolt 24, thereby fixing the second protective door 7 on the second baffle 9. The second protective door 7 is sealed by the first sealing strip 12, which can prevent the tail gas in the first filter chamber 11 from moving outside the tower body 1 and polluting the surrounding air. When replacing the filter bag 18, remove the second bolt 24, open the second protective door 7, and move the filter block 16 outside the tower body 1 through the handle 21, which is convenient for the staff to replace the filter bag 18 and can prevent the stains in the first filter chamber 11 from contaminating the staff's clothing. The filter bag 18 is inserted into the installation groove 22 through the installation block 15. The insertion installation method is convenient for the staff to replace the filter bag 18, reducing the time for replacing the filter bag 18 and thus improving the working efficiency of the bag filter equipment.
