Abstract

The invention discloses a graphite dust collecting and nuisanceless disposing device. A graphite dust disposing device comprises a dust-collecting mechanism and a dust-removing mechanism, wherein the dust-removing mechanism comprises a dust-removing passage, at least one electrode positioned inside the dust-removing passage, at least one gas inlet passage, a detection device and at least one power supply device; the electrode is made of a resistance wire; the gas inlet passage is used for making graphite dust-containing gas, auxiliary combustion gas or a mixture of both enter into the dust-removing passage; the detection device is used for detecting the dust concentration at an outlet of the dust-removing passage. By virtue of an electrostatic adsorption principle, the graphite dust disposing device collects graphite dust in compressed air, enables the graphite dust to be adhered to the resistance wire, and burns the graphite dust, so that adsorption, collection and nuisanceless disposal of the graphite dust are implemented.

Description

technical field [0001] The invention belongs to the technical field of waste recycling, in particular to a device for collecting graphite material dust and pollution-free treatment. Background technique [0002] Since graphite material is a brittle material and cooling fluid is usually not used in the processing process, a large amount of dusty chips are easily generated during the mechanical processing of graphite material. Dust-like graphite chips not only have adverse effects on the health of on-site personnel, but also because graphite is conductive, graphite dust can easily cause short circuits in the surrounding electrical control systems or power grids and cause accidents. [0003] The collection and treatment of graphite chips is one of the important problems faced in the production process of graphite parts. The existing dust removal methods mainly use physical dust removal, that is, use a vacuum cleaner to collect chips in a certain container, or use a liquid to f...
