    Selection of dust filter bag


    When the gas and dust are acidic and neutral, it is good to use dust-removing cloth bags (filter bags) made of polyester and polypropylene that are resistant to most inorganic and organic acids.

    The dust bag (filter bag) has short life and is easy to break. From the analysis results of the dust bag (filter bag) after use, in most cases, it is performed under conditions that exceed the performance of the dust bag (filter bag). There are many examples of short life of dust-removing cloth bags (filter bags) caused by use, especially due to the influence of high temperature.
    Due to management deviation, the gas temperature often changes for a long time in a state that exceeds the heat-resistant temperature of the dust-removing cloth bag (filter bag), so it should be appropriate to use a dust-removing cloth bag (filter bag) with higher heat resistance.
    The choice of dust cloth bags (filter bags), as mentioned above, various dust cloth bags (filter bags) can not have the indispensable performance in meeting the requirements of temperature, humidity and chemical corrosion and other conditions. Therefore, the correct selection of the dust bag (filter bag) will become an important part of the bag filter to fully display its effectiveness, and should be selected according to the following principles:
    Select dust-removing cloth bags (filter bags) according to the properties of the dust, first analyze the measurement results based on the filtered gas and dust properties, and refer to the performance of various dust-removing cloth bags (filter bags).
    In addition, the design of the dust collector must meet the performance of the fiber used in the dust bag (filter bag). When the polyester dust bag (filter bag) filters alkaline gas, due to the effects of temperature and humidity, it will be decomposed by water, resulting in a significant decrease in the strength of the dust bag (filter bag). Therefore, in this case, use a nylon dust bag (filter bag) instead.
    Due to the price and other aspects of this dust filter bag (polytetrafluoroethylene, etc.), its scope of application is subject to certain restrictions, so you must be very careful when choosing it. When the gas and dust are acidic or neutral, it is good to use a dust-removing cloth bag (filter bag) made of polyester and polypropylene, which is resistant to most inorganic and organic acids. However, note that when the temperature of the flue gas exceeds 80 ° C, the strength of polypropylene will deteriorate.
