Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to an anti-clogging SDS desulfurization bag dust collector. Background Art

[0002] SDS desulfurization bag dust collector is a device used to treat sulfur dioxide (SO2) in flue gas. It is usually used in industrial processes such as thermal power plants. During the long-term flue gas filtration process, the sulfuric acid particles and other particles trapped in the internal bag will adhere to the bag surface, affecting the bag's filtration efficiency. In severe cases, it will cause the bag to be blocked. Therefore, the staff needs to regularly clean the impurity particles adhering to the bag surface. At present, there are the following deficiencies in the cleaning of the bag:

[0003] (1) If manual cleaning is used, the staff must enter the bag dust collector to clean it, which is not only inconvenient to operate, but also causes the staff to inhale foreign particles into the body, causing harm to the staff's health;

[0004] (2) Nowadays, most bag dust collectors use a reverse blowing system for cleaning. However, the existing reverse blowing can only ensure that the bag is blown in the reverse direction, and cannot evenly and fully blow the bag from the inside to the outside, resulting in incomplete cleaning of the bag;

[0005] (3) The disassembly and assembly of the bags in the existing bag dust collector is very cumbersome, which greatly reduces the efficiency of the staff's inspection and maintenance of the bag dust collector;

[0006] Therefore, an anti-clogging SDS desulfurization bag dust collector is urgently needed. Utility Model Content

Specifically, the support frame 8 includes a clamping ring 20, a connecting rod 22 and a connecting ring 23. The outer diameter of the clamping ring 20 is larger than the diameter of the installation port 6, and the inner diameter is smaller than the diameter of the installation port 6. The upper surface of the clamping ring 20 is provided with a vibration motor 19, and the vibration motor 19 is controlled by an external power supply. The lower surface of the clamping ring 20 is provided with a plurality of connecting rods 22 that are perpendicular to the lower surface of the clamping ring 20 and uniformly distributed along the circumference of the clamping ring 20. The rod bodies of the plurality of connecting rods 22 are provided with a plurality of connecting rods 22 that are spaced axially from the connecting rods 22. The connecting ring 23 is arranged in order and parallel to the clamp ring 20, and is blocked at the upper part of the installation port 6 by the clamp ring 20. The several connecting rods 22 and the connecting ring 23 at the lower part of the clamp ring 20 are inserted into the filter cavity 11 through the installation port 6. The cloth bag 10 is sleeved on the outside of the several connecting rods 22 and the connecting ring 23. The upper part of the tank body 12 is provided with a connecting pipe 2 with one end connected to an external blowing device and the other end inserted into the exhaust cavity 3. The connecting pipe 2 located in the exhaust cavity 3 is provided with several connecting rods 22 and the connecting ring 23 connected to the installation port 6. A flushing pipe 5 corresponding to and protruding into the support frame 8, a plurality of air nozzles 9 are evenly distributed on the pipe body of the flushing pipe 5, a plurality of through ports 13 connecting the filter chamber 11 and the dust collecting chamber 16 are arranged on the surface of the lower partition plate 14, an air inlet 15 connected to the dust collecting chamber 16 and an air outlet 4 connected to the exhaust chamber 3 are arranged on one side of the tank body 12, a dust outlet 17 connected to the dust collecting chamber 16 is arranged at the bottom of the tank body 12, and a fan 18 connected to the dust outlet 17 is arranged at the lower part of the dust outlet 17;

[0029] When cleaning the cloth bag 10, turn on an external blowing device, such as a blower, and send the air flow into the flushing pipe 5 through the connecting pipe 2, and spray gas outward through the air nozzle 9 on the body of the flushing pipe 5, so as to blow gas out from the inside of the cloth bag 10 to the outside, and use the gas to blow off the dust and impurities adhering to the surface of the cloth bag 10. In order to improve the cleaning efficiency of the cloth bag 10, the vibration motor 19 can also be started, and the vibration motor 19 can be used to drive the vibration of the support frame 8, so that the dust and impurities adhering to the surface of the cloth bag 10 can be quickly shaken off. In order to prevent the several connecting rods 22 at the bottom of the support frame 8 from colliding and wearing with the mounting port 6, a rubber pad 21 is provided on the inner wall of the mounting port 6, and the several connecting rods 22 at the bottom of the retaining ring 20 are interference fit with the mounting port 6.

After taking it out, the bag 10 is removed from the support frame 8 to complete the disassembly and assembly of the bag.

[0031] Embodiment 3: When the dust-containing gas is blown in through the air inlet 15, a large amount of dust will float in the dust collecting chamber 16. In order to prevent the dust from entering the filter chamber 11 in large quantities along with the gas, the lower end of the through-port 13 is a conical structure, which not only makes the lower end of the through-port 13 have a sufficient size to guide the gas into the filter chamber 11, but also can block the dust in the gas, thereby reducing the amount of dust entering the filter chamber 11.

[0032] After the dust filtered out of the filter chamber 11 falls onto the lower partition 14, in order to prevent the dust from accumulating on the lower partition 14, the upper end of the through opening 13 is an inverted cone structure, which not only makes the upper end of the through opening 13 have a sufficient size to receive the dust, but also can guide the dust into the dust collecting chamber 16 through its cone surface.
