Reasons for powder leakage during high-temperature bag type dust removal
In production, the common products of high-temperature cloth bag dedusting mainly include Flumex needle felt dedusting cloth bags, PPS needle felt dedusting cloth bags, PTFE needle felt dedusting cloth bags, etc. These products have good high temperature resistance and corrosion resistance, and can still work stably in a very bad environment, but their prices are also higher than ordinary polyester needle felt dedusting bags. Recently, some customers have reported that powder leakage often occurs in the process of bag dedusting.
First of all, it is because the wind speed of the bag type dust remover is too high, which causes damage to the high-temperature dedusting bag. In order to reduce the manufacturing cost of the equipment, some bag filter suppliers will deliberately increase the wind speed of the bag filter, which is generally not found by customers. However, this practice greatly reduces the use time of high-temperature resistant bag filter, which greatly increases the cost of operating high-temperature bag filter for customers.
Secondly, it is because the working temperature of the bag filter exceeds the bearing range of the high-temperature dedusting bag, which is one of the reasons for the damage of the high-temperature dedusting bag. If the working temperature greatly exceeds the range that the bag can withstand, the bag will be burnt in a short time during the high-temperature bag dedusting process.
In addition, the performance of high-temperature dedusting cloth bag is also the key factor affecting its service life. Some customers do not understand the performance of each material's high-temperature dedusting bag, but choose the wrong type of high-temperature dedusting bag, which makes the performance of the high-temperature dedusting bag inconsistent with the actual working environment, resulting in the damage and burning of the dedusting bag.
The so-called high-temperature dedusting bag refers to the working condition with the working temperature ≥ 200 ℃, and the maximum working temperature can reach 300 ℃, including: METAS dedusting bag, Flumex dedusting bag, PPS dedusting bag, glass fiber needle felt dedusting bag, P84 high-temperature resistant dedusting bag. Each kind of high temperature bag type dust remover has different working conditions, so please choose.
