Dust collector bag is an important part of the bag filter, the dust collector bag is equivalent to the heart, the other accessories to help it get the cleaning effect, when we found that the dust collector dust removal effect is not ideal, it is possible to dust bag aging Oh.
Dust master analysis of dust collector bag aging mainly for the following reasons:
1, the working conditions temperature anomalies.
If the temperature is too high, will lead to the dust bag is burned black, burned; if the temperature will slow down the dust bag bag condensation phenomenon, resulting in its prone to paste bag phenomenon, over time the dust collector bag will be aging, and even affect the use the term.
2, acid-base imbalance.
Dust bag and acid, alkali contact will cause the dust bag is corroded, so a long time acid-base imbalance, will lead to dust bag aging.
3, the moisture in the flue gas.
Some dust collector bags and moisture contact for a long time will be broken down, such as polyester as the material of the dust bag, so the water decomposition of the dust bag more easily aging.
4, dust bag bag plug.
The resistance will increase after blocking, cleaning interval will be shortened, these factors will accelerate the aging of the dust collector bag.
Dust Collector System Piping When the transport medium contains combustible gas or flammable and explosive dust, the piping system design should take the following explosion protection measures.
(1) to strengthen the detection and control of combustible concentration
In order to prevent the concentration of combustible material in the pipeline system to reach the explosive concentration, the necessary detection equipment should be set up so as to monitor the working status of the system frequently and realize the automatic alarm. In the design of the system air volume, in addition to consider to meet the purification requirements, but also check the concentration of combustibles, if necessary, increase the design of air volume to ensure that the transport of fuel concentration below the lower explosive concentration.
(2) to eliminate the fire source
On the possible fire caused by the explosion of strict control. Such as the use of explosion-proof fan, and the use of direct or shaft drive mode; the use of explosion-proof electrical components, switches, motors; materials into the system before the elimination of iron and other foreign matter.
(3) fire and venting measures
When designing a combustible gas pipeline, the minimum flow rate in the pipe should be greater than the flame propagation rate during the combustion of the gas to prevent flame propagation. Install a number of metal fire or gravel flame arrester on the pipe; in the local location (dead) of the piping system Set the vent hole or vent gate; gas pipe used in the connection of water seal and overflow water seal can also play a certain role in the vent.
(4) The equipment is sealed
When the dust collector pipe and equipment is bad, it may occur due to air leakage or combustible leakage and combustion explosion. Therefore, the equipment system must be sealed.
(5) plant ventilation
It is imperative to ensure that the piping system is absolutely closed, so it is necessary to strengthen the ventilation of the plant to ensure that the concentration of combustibles in the workshop is not dangerous. In addition, there is a workshop where a large amount of combustible gas is distributed when an accident occurs due to an accident or a system failure occurs. An exhaust system should be set up for emergency use.
