The design points of bag filters are mainly based on relevant national and local standards as well as the contract documents signed between the user and the designer. In the contract documents, key matters such as the specifications of the dust collector, the level of equipment, the expected service life, the supply of spare parts, and the specific content of technical services must be clearly defined.
As an environmental protection device closely serving the production process, it is extremely crucial to deeply understand the production process during the design of the bag filter. It is necessary to comprehensively grasp the current situation and future development plan of the process layout, anticipate possible sudden accidents during production, and at the same time, deeply study the characteristics of the smoke and dust and the specific requirements these characteristics impose on the dust collector.
The design of the bag filter focuses on determining various key parameters based on the characteristics of the flue gas entering the dust collector. However, it should be noted that the characteristics of the flue gas are not static. Although they are relatively stable to a certain extent, fluctuations and changes often occur during the actual operation of the production process. Therefore, during the actual application stage, it is necessary to fully and comprehensively master the real - time operation dynamics of the production process to ensure that the design of the dust collector can flexibly adapt to various changes in the production process. Only in this way can we effectively avoid malfunctions in the operation of the dust collector due to the particularity of production, thereby affecting the normal operation of the entire production system.
Among the key components of the bag filter, the electromagnetic pulse valve plays a pivotal role. It is the core component of the bag filter's ash-cleaning system. When a certain amount of dust adheres to the surface of the filter bags of the dust collector, it will affect the dust-removal efficiency and the operating resistance of the equipment. At this time, the electromagnetic pulse valve will open instantaneously according to the pre-set program and release a powerful compressed-air pulse. This pulse airflow can impact the filter bags at high speed, causing the filter bags to vibrate violently, thereby shaking off the dust attached to the surface of the filter bags and achieving the ash-cleaning process of the filter bags. In addition to the electromagnetic pulse valve, there are other important components. For example, the filter bag is a key component for directly filtering dust, and its material and structure determine the filtration accuracy and efficiency; the skeleton provides support for the filter bag, ensuring that the filter bag maintains a stable shape during the working process and preventing the filter bag from being deformed and damaged due to factors such as air - flow impact. These components cooperate with each other to jointly ensure the efficient and stable operation of the bag filter.
