The coal bag boiler dust collector has a short life, a large amount of maintenance work, high maintenance costs, and a heavy economic burden on the company. After many years of reform and replacement of the coal-fired boiler dust collector bag, the damage of the PPS dust bag The time can be avoided.
The temperature of the dust bag is also used to cause damage. When the user selects the dust bag, the temperature of the dust removal device must be taken into consideration. If the temperature is too high, the filter bag will be burned or its service life reduced. Therefore, the dust should be selected according to the temperature. Bags.
First, filter the wind speed
The excessive filtering speed of the bag filter of the coal-fired boiler is the main reason for the damage of the PPS dust bag. In recent years, some units have blindly reduced the cost of equipment and increased profits. When designing bag filters, the filter speed has been increased. The users have no obvious reaction in a short time, but the service life of the filter bags has been greatly shortened. In this way, giving customers not only does not save money, but also brings a very large economic burden and wastes time.
The main function of the PPS dust bag is the dust medium absorbed by the mobile phone dust collector. Therefore, in some acidic or alkaline media environments, the filter bag with good corrosion resistance should be selected. If it is common, it will inevitably cause corrosion of the bag.
Second, the use of temperature
The correct selection of dust bag suitable for the corresponding dust temperature is the key to the filter bag. If the temperature is too high, the filter bag used is selected to exceed the normal operating temperature. If the filter bag is light, the service life is shortened and the filter bag is severely burned in a short time. Therefore, when selecting the filter bag, it must be determined to calculate the inlet temperature of the filter, and select the corresponding dust bag.
The most direct reason for the damage of PPS dust bag is the quality of the product. Nowadays, there are too many pursuits by some manufacturers for the dust removal frame. No matter what the material selection or production is, the quality of the product is poor and the filter bag often appears on the line. The phenomenon of falling out of the bottom and cracking has seriously affected the use of dust removal equipment. The excessively high filtration speed setting of the dust removal equipment directly leads to a shortened life of the dust bag. Although the reaction will not occur in the short term, the life of the bag is shortened. It’s cheap to buy, but it doesn’t take long to use. It’s also a very big economic loss for users, and more importantly, it wastes time.
Third, product quality
The processing of PPS bags is particularly important. In recent years, some small manufacturers use small sewing machines as processing equipment, and use inferior quality lines as raw materials during processing, which is far from real and the level of processing is far behind. The use of dust bag in the use of time is not long, there will be open lines, cracks, falling bottom and so on. Although the bag size is slightly smaller, it can be used. However, after the dust having a larger specific gravity is adsorbed, the bag falling phenomenon will occur for a certain period of time.
