Description

Technical Field

[0001] The invention relates to the technical field of bag dust collectors, in particular to a bag dust collector. Background Art

[0002] Existing low-pressure pulse bag dust collectors may have the following deficiencies and defects when cleaning:

[0003] 1. High requirements for air source: A stable and clean compressed air source is required. If the compressed air contains oil, water or other impurities, it may cause the pulse valve to malfunction, affect the cleaning effect, and may also cause the filter bag to become damp and sticky, reducing the service life of the filter bag and even causing the filter bag to become blocked.

[0004] 2. It is difficult to accurately control the cleaning intensity and frequency: The cleaning intensity and frequency need to be reasonably adjusted according to the actual working conditions. If the cleaning intensity is too high or the frequency is too high, it may accelerate the wear of the filter bag and shorten the service life of the filter bag; if the cleaning intensity is insufficient or the frequency is too low, the dust accumulated on the surface of the filter bag cannot be effectively removed, resulting in increased resistance of the dust collector and affecting the dust removal efficiency.

[0005] 3. There may be local uneven cleaning: In large low-pressure pulse bag dust collectors, due to the influence of factors such as the length of the blow pipe and airflow distribution, some filter bags may not be cleaned well, while some filter bags may not be cleaned thoroughly, resulting in poor overall cleaning effect.

[0006] 4. Risk of filter bag damage: Although low-pressure pulse cleaning causes less damage to filter bags than high-pressure pulse cleaning, frequent pulse blowing may still cause local wear and tear of the filter bags during long-term operation, especially at the bag opening and bag bottom, increasing the replacement frequency and maintenance cost of the filter bags.

[0007] To this end, we propose a bag dust collector. Summary of the invention

[0039] Compared with existing technologies:

[0040] Improve cleaning efficiency: The filter bag is flipped to fully expose the inner and outer surfaces of the filter bag. Reverse blowing can directly act on the dust accumulation area and completely remove the dust from the surface of the filter bag. Compared with traditional cleaning methods, it can more efficiently remove dust on the surface of the filter bag and maintain good filtering performance of the filter bag.

[0041] Reduced operating resistance: Due to more thorough cleaning, the amount of dust accumulated on the surface of the filter bag is greatly reduced, thereby reducing the operating resistance of the dust collector. This means that at the same processing air volume, the energy consumption of the fan can be reduced, saving operating costs.

[0042] Improve filtration accuracy: Clean filter bags can better play a filtering role, effectively intercept dust particles, improve the filtration accuracy of the dust collector, make the exhaust gas cleaner, and meet more stringent environmental protection requirements.

[0043] Reduce maintenance workload: The extended service life of the filter bags and improved cleaning effect reduce the frequency of filter bag replacement and equipment maintenance, and reduce maintenance workload and maintenance costs. At the same time, the stable cleaning effect also reduces equipment failures caused by cleaning problems and improves the operating stability of the equipment.

[0044] Enhanced adaptability: This cleaning method has stronger adaptability to dusts with different characteristics. Whether it is sticky dust or ordinary dust, it can achieve better cleaning effects. Therefore, this cleaning method can be applied to dust removal systems in more different working conditions.

[0045] It can solve the problem of cleaning sticky dust: for dust with high stickiness, it is difficult to completely remove it from the surface of the filter bag by traditional cleaning methods, which can easily cause the bag to become sticky. The filter bag flipping process can loosen the dust layer on the surface of the filter bag, and combined with reverse blowing, it can better overcome the sticky force between the dust and the filter bag, effectively remove the sticky dust, and avoid the occurrence of bag sticking.

[0046] Can solve the problem of filter bag damage: Frequent pulse blowing in traditional pulse cleaning may cause local wear and tear of the filter bag; while the cleaning process of the filter bag flipping and reverse blowing is relatively gentle, which reduces the direct impact force on the filter bag, reduces the risk of filter bag damage due to cleaning operations, and extends the service life of the filter bag.

[0047] Able to solve the problem of air source impurities: Traditional low-pressure pulse bag dust collectors rely on compressed air for cleaning. If the air source contains oil, water or impurities, it will affect the cleaning effect and the life of the filter bags. The filter bags can be flipped and reversed for cleaning, which can use relatively clean reverse airflow and is less sensitive to air source impurities, thus reducing the impact of air source quality on the cleaning effect.
