[0002] Spark capturing device is generally installed in the air inlet front of dust remover, and main role is to process some high temperature and contain spark flue gas to remove the spark therein. For example, the flue gas of cupola, the flue gas of intermediate frequency furnace, the primary flue gas of converter etc. Spark capturing device is particularly important for bag filter, because the filter bag of bag filter is relatively fragile, if there is spark in flue gas, then the filter bag of dust remover is extremely easy to burn out.

[0003] Spark capturing device exists multiple structure forms, has gravity sedimentation type and louver type etc. The basic mechanism of gravity sedimentation type is an expansion chamber, and dust particle speed is reduced to reliable gravity sedimentation speed in expansion chamber, and the upper portion of expansion chamber is added with baffle plate, so that the direction of airflow is changed to add downward speed to dust particle, and the separation of dust particle can be improved. The louver type is internally provided with louver type filter plate, and plays the role of baffle plate, when flue gas enters and collides with the louver type filter plate at higher airflow, the direction is changed, and the speed is reduced, and then gradually settles down. The existing spark capturing device has problems such as large resistance and incomplete spark capturing. UTILITY MODEL CONTENT
