Different types of dust bags have different stains inside, so that the methods and steps required for cleaning are different, but of course this we still need to simplify or increase the number of cleaning steps according to the actual situation. Common dust bag cleaning steps such as experiments for processing, bag cleaning, bag drying, bag repair, bag testing, etc. 1. Dust bag using high-frequency vibration, vibration can be as soon as possible through the filter bag above the various impurities to clean up a part. The larger dust particles entering the surface of the filter bag will be removed as far as possible, and will not have an impact on the fastness of the fiber entanglement, to maintain good peel resistance of the filter bag. 2. Dust bag chemical experimental treatment, which can not only deal with the bag impurities, at the same time will not damage the bag material. Extract bag samples, the use of professional instruments, laboratory testing of filter bag oil composition, so as to choose the appropriate washing materials, the maximum wash filter bag without causing any damage to the filter bag. 3. Dust bag cleaning can better help remove the stains of the bag Choose suitable washing materials and strict ratio, low temperature water cleaning, even water flow, moderate strength, no mechanical damage to the filter bag. 4. Drying of dust bag can guarantee better flatness of the bag without deformation Use 110℃ hot air drying, keep the size stability of dust filter bag, no deformation and no shrinkage after drying. 5. Dust bag repair can better protect the integrity of the bag Repair of damaged filter bags such as abrasion and holes due to use ensures a high reuse rate. 6. Dust bag testing can guarantee whether the bags are cleaned to standard The physical indicators of the cleaned filter bags are tested by instruments to ensure that the cleaning quality meets the requirements.

The design of the fiber fabric of different dust-removing bags is to pursue high-efficiency filtration as much as possible, and pursue a longer service cycle. So how to choose the right dust collector bag? The dust filter sleeve is a key component of the bag filter. Generally, it needs to be determined according to the acid-base performance of the dust, the chemical nature of the gas containing the dust, the temperature of the working condition, etc., so it is different for different working conditions. The focus of selection is also different. According to the nature of the gas under the working conditions, select the suitable dust filter sock that is resistant to high temperature or humidity Temperature: The temperature is lower than 130 degrees, you can choose the conventional baghouse bag such as polyester dust bag, the temperature is greater than 130 degrees, you need to choose high temperature dust bag, such as flumesi dust bag, PTFE dust bag, etc. Humidity: The choice of gas humidity. The product engineering department of Xinwei Environmental Protection, based on actual working condition experience and test conclusions, when the relative humidity of the gas in the working condition is greater than 30%, we should choose a waterproof cloth bag with a film. Acid and alkali: Fully consider the acid and alkali properties in the working conditions. Various types of kiln boilers often contain acid and alkali. The performance is different and the corrosive working conditions. Therefore, it is necessary to choose different use of acid and alkali resistance or Anti-oxidant dust bag. The industrial filter bag is selected according to the special nature of the dust. 1. The wettability and adhesion of dust. If the dust is dust-absorbing and highly adhesive, choose a dust-removing filter bag with a waterproof membrane filter material. 2. The combustibility and nuclear power of dust. Certain dusts are flammable, and flame-retardant dust collection bags should be selected. Dust filter bags are specially used for nuclear power dust. Select the dust collection bag according to the dust removal method of the dust collector. 1. Mechanical vibration type bag filter. It is required to choose a filter material that is thin and smooth, with a soft texture, and is conducive to the transmission of vibration waves, such as PTFE dust bag. 2. Back-blowing bag type dust collector. Pulse bag filter. The outer filter round bag with frame is usually used. It is required to choose thick, wear-resistant, and strong tension resistance. For example, Metas dust bag and so on.
