The mining bag filter adopts a high-pressure fan equipped with equipment to blow back and clean the dust, which is not limited by the gas source conditions of the application site. It has fewer vulnerable parts, is easy to maintain, operates well, overcomes the disadvantages of compressed air pulse cleaning, has a long blowing distance, can use long filter bags, and fully utilizes space. At the same time, the mining bag filter occupies a small area.
The mining bag filter adopts a ladder shaped flat bag arranged inside the cylindrical body, with a simple and compact structure, and the filtering area refers to the elevation. Under the action of counter blowing, the trapezoidal flat bag has a large amplitude, and only one vibration is needed to shake off the accumulated dust, which is beneficial for improving the service life of the filter bag.
According to the characteristics of the dust source, wet dust control measures such as spraying dust suppression, spray dust suppression and covering dust prevention are adopted for the mine bag type dust remover. When wet dust prevention is unconditionally used in frozen and water scarce areas or cannot meet the required standards after wet dust prevention, a comprehensive method of mechanical dust removal or a combination of mechanical dust removal and wet dust prevention should be used. Mechanical dust removal equipment should be suitable for the characteristics of mines, requiring simple structure, small and compact size, easy migration, stable and practical performance. When comprehensive dust prevention measures cannot meet the requirements in each operation process, personal protection measures need to be taken.
Precautions for operating bag filter in mines:
The operation of mining bag filter can be divided into trial operation and daily operation. Firstly, during the trial operation, the individual components of the system should be inspected, followed by adaptive operation and partial performance testing. In daily operation, necessary inspections should still be carried out, especially for the performance of the bag filter of the crusher. Pay attention to the impact of changes in the load of the host equipment on the performance of the dust collector. After the machine is started, close attention should be paid to the working condition of the bag filter and relevant records should be kept.
