There are many reasons why dust collection bags burn out, but the main cause is usually temperature. The operating environment for dust removal filter bags is generally quite extreme, especially as high temperatures have a significant impact on these bags. I. Filtration air velocity An excessively high filtration air velocity in bag dust collectors is the main cause of damage to the collector’s filter bags. In recent years, some companies have blindly sought to reduce equipment costs in order to increase profits; when designing bag filters, they have increased the filtration air velocity. Users do not notice any obvious effects in the short term, but this **reduces the service life of the filter bags**. As a result, this not only fails to save the customer money but also imposes a heavy financial burden and wastes time. II. Dust Medium The choice of fabric for dust collector bags depends on the properties of the dust; it is necessary to consider whether the dust contains acids, bases, or other highly corrosive substances. Selecting a filter media suitable for the properties of the dust ensures that the filter bags can effectively absorb dust without affecting their service life. III. Operating Temperature Choosing the right dust collector filter bags that are suitable for the temperature of the corresponding dust is crucial for these filters. If the temperature is too high, the dust collector filter bags used will be exposed to temperatures beyond their normal operating range; this may shorten their service life, or in severe cases, cause them to burn out in a short time. Therefore, when selecting filter bags, it is essential to measure and calculate the dust collector inlet temperature before choosing the appropriate dust collector bags. The effectiveness of dust removal by dust collectors generally depends on various factors, but it is primarily determined by the bag cover; this cover is made of fabric or felt woven from synthetic fibers, natural fibers, or glass fibers. The protective cover can be made by weaving cotton, wool fibers, glass fibers, or various chemical fibers into filter media, which are then sewn into vertically hanging filter bags; different filter media should be selected for different applications. Sew the cloth or felt into bead-type dust collector bags as needed
If the quality of the filter bags is poor, turn to me – we specialize in producing filter bags, dust collection cartridges, as well as other dust removal components such as plastic burn plates
The inlet and outlet pressure difference, inlet temperature alarm, and interlock can be considered.
Solutions for bag burning require a comprehensive consideration of various factors.
If the feeding is uneven and detonations occur frequently in the furnace, sparks can quickly reach the bag filter at the rear, causing damage to it. This is the accident status.
The original poster has only provided a qualitative description; could a quantitative analysis be given, such as the maximum allowable wind speed, and what smoke temperature typical fabric bags can withstand?
