TECHNICAL FIELD
[0001] The utility model relates to the technical field of cyclone separator, especially relates to a matrix type parallel cyclone separator set. BACKGROUND
[0002] Cyclone separator is one of the important equipment in the field of modern industrial dust removal, and the traditional single cyclone separator has many shortcomings in practical application. Its processing capacity is often limited by the size of the equipment. In order to meet the requirements of process flow on the treatment gas volume, it is necessary to increase the processing capacity of the cyclone separator. The single cyclone separator needs to significantly expand the volume, but the oversized equipment not only occupies space, but also increases the manufacturing cost and installation difficulty. At the same time, the separation efficiency of single cyclone separator is greatly affected by the stability of airflow. In high gas flow conditions, airflow turbulence or vortex shedding may occur inside the equipment, which may lead to a decrease in separation efficiency and difficulty in dealing with large changes in flow or dust concentration. In addition, the single cyclone separator is easy to be damaged in high abrasion or corrosion conditions, which leads to frequent maintenance or replacement and affects the overall reliability of the system. These shortcomings make the single cyclone separator less adaptable to different working conditions and gas characteristics, making it difficult to meet the needs of modern industry for high efficiency, compactness and diversification, and it is urgent to use new design to improve the system performance.
[0003] Compared with the traditional single cyclone separator, the matrix type parallel cyclone separator has obvious advantages in handling high gas flow. The matrix type parallel cyclone separator can effectively improve the overall processing capacity by reasonably arranging multiple cyclone separation units to disperse large gas flow to multiple small separation units for processing. The gas flow handled by each separation unit is relatively small, which can ensure more stable internal airflow and avoid efficiency reduction caused by high flow rate or turbulence. Moreover, the matrix type parallel cyclone separator realizes the maximization of processing capacity per unit volume through compact design. Multiple cyclone units are usually arranged in a matrix type, and the overall equipment occupies less space, which is convenient for installation in limited space. At the same time, the matrix type parallel structure is composed of multiple independent cyclone separator units, each unit has a relatively independent working channel, and when maintenance or maintenance is needed, the faulty unit can be handled individually without stopping the whole system. This feature greatly improves the continuity and stability of system operation.
[0004] However, the uneven airflow distribution has a significant impact on the operation performance and stability of the matrix parallel cyclone separator, which can result in reduced separation efficiency, unbalanced unit load, increased pressure loss, weakened system stability, and intensified particle re-entrainment. When the airflow is unevenly distributed in each cyclone separation unit, the units with excessive airflow can destroy the internal flow field stability due to enhanced turbulence, leading to a decrease in separation efficiency, while the units with insufficient airflow cannot fully separate particles due to insufficient energy. This unbalanced load condition can cause some units to operate for a long time under excessive load, leading to accelerated wear and even shortened equipment life, while other units are not effectively utilized, resulting in resource waste.
[0005] Therefore, in order to overcome the problems of limited processing capacity and non-compact structure of the traditional single cyclone separator, and to improve the problem of reduced separation efficiency caused by uneven airflow distribution of parallel cyclone separators, a matrix parallel cyclone separator group can be designed.
