The method for detecting the dust of the pulse bag filter is as follows:
(1) The clean dust collecting bag newly installed in the pulse bag type dust collector has larger pores, and the dust passing rate is higher when the pulse bag type dust collector is used for the first time. The pulse bag type dust collector has not yet reached the optimal filtering state, and the dust emission amount Larger ... With the progress of filtration, dust accumulates on the outer surface of the filter bag to form a dust layer, which makes the pores on the outer surface of the filter bag smaller and improves the dust removal efficiency. The "dust filter" effect can remove more than 99% of fine dust. Therefore, it is more accurate to measure the dust removal efficiency of the pulse bag dust collector after one month of continuous use.
Method for detecting dust in the pulse bag type dust collector (2) Check whether the filter bag of the pulse bag type dust collector is installed correctly. The ordinary pulse bag type dust collector relies on the elastic expansion ring sewn in the mouth of the filter bag to press the filter bag into the hole of the flower plate. The flower plate strictly separates the dust chamber of the middle box from the clean air chamber of the upper box. . If the elastic expansion ring at the mouth of the filter bag does not fully match the faceplate hole, a gap will be generated, which will cause the dust-containing airflow to directly enter the clean air chamber and generate a mist at the outlet of the exhaust cylinder. Check the installation of the filter bag openings one by one. If there is a gap, you need to tightly seal. During the installation of the pulse bag type dust collector, the installation quality of the filter bag is one of the key points of supervision and inspection. The installation has been improved and optimized: a ferrule is welded above each flower plate hole, the ferrule is 30 mm high, concentric with the flower plate hole, and a single layer of elastic expansion ring on the seam of the filter bag is closely attached to the inner wall of the ring It not only ensures the smooth installation of the filter bag, but also makes the installation and removal of the filter bag easier.
(3) The damage of the filter bag of the pulse bag type dust collector will directly discharge the dust-containing airflow, and the outlet of the exhaust tube behind the pulse bag type dust collector will discharge dust. For large-scale pulse bag dusters for off-line cleaning, the following methods can be used to determine the bag breaking position: manual cleaning of one room at a time, close the exhaust valve of one room at a time, pay attention to the exhaust pipe outlet. The exhaust pipe outlet is no longer dusty. Based on this, you can determine which chamber has a broken bag. If only a few filter bags are damaged, and the disc hole is sealed with an iron cap, the discharged dust concentration can be guaranteed. When the filter bag needs to be replaced, it is recommended that all the dust bag of the same pulse bag type dust collector be replaced at the same time to ensure that each filter bag has the same resistance. If only a few filter bags can be replaced, the bag mouth of the new filter bag needs to be closed and buried in the dedusting ash for a few days to increase the resistance of the new filter bag and make the resistance of the new filter bag close to the old filter bag.
Pulse bag dust collector dust detection method (4) For a vacuum cleaner in which the air inlet passage and the air outlet passage are separated only by the partition, it is necessary to check whether the intermediate partition is welded firmly. If there are welding seams and gaps in the middle partition, the high concentration of dust at the air inlet will enter the air outlet channel, resulting in dust emission at the exhaust outlet. Ensuring the welding quality of the intermediate partition and completely separating the inlet and outlet channels is another focus of quality inspection during the production and installation of pulse bag dust collectors.
