De-dusting System and Principle of DTH Drilling Rigs
During the operation of a DTH drilling rig , not only is the dust concentration at the workplace high but also the dust particles are widely distributed. During the drilling operation, the rock dust is blown from the bottom of the hole to the ground by the compressed air, and if no measures are taken, it will spread in the atmosphere and form environmental pollution. In other words, the dust removal effect of the drilling rig is an important performance indicator to evaluate the drilling rig. De-dusting method There are two types of de-dusting methods: one is wet de-dusting and the other is dry de-dusting. The two types of dust removal methods have different effects on different rock properties and hydrogeological conditions. Dry de-dusting uses cyclone separation and filtration, while wet de-dusting uses water spraying in the compressed air to moisten the rock powder so that it does not drift away. Dry-type dust removal requires regular replacement of filter cartri...
