Description

Technical Field

[0001] The invention belongs to the technical field of dust removal, and in particular relates to a grid-type metal spark separation device applied to a dust removal pipeline. Background Art

[0002] In industrial production, some processes will generate a lot of metal sparks, such as cutting, welding, grinding, etc. If these metal sparks enter the dust removal pipeline, they will damage the filter material, fan and other equipment in the pipeline, and even cause fire and explosion. Therefore, it is necessary to set a device in the dust removal pipeline to effectively separate the metal sparks and protect the safe operation of the dust removal system.

[0003] At present, there are many devices for separating metal sparks, such as water bath type, cyclone type, electromagnetic type, etc. Among them, the water bath type device mixes the metal sparks with water, uses the cooling and quenching effect of water to make the metal sparks inactive, and then separates them by sedimentation or filtration. The cyclone type device separates the metal sparks from the airflow by using the centrifugal force of the cyclone separator. The electromagnetic device uses the effect of the electromagnetic field to adsorb the metal sparks on the electrode.

[0004] However, these existing technologies all have certain disadvantages and shortcomings. For example, water bath devices consume a large amount of water resources and produce wastewater containing metal particles, which needs to be treated and recycled. Cyclone devices require a large space and have high requirements for the speed and direction of the airflow. Electromagnetic devices consume more electricity and have high requirements for the material and shape of the metal sparks. Summary of the invention
