Water mist dust removal apparatus for graphite production

Abstract

The invention discloses a water mist dedusting device for graphite production, which includes a suction fan, a flue, a cold water pipe, and a dust removal tank. One end of the flue is connected to a suction fan, and a graphite production workshop is arranged below the suction fan. The suction fan is installed on the top of the graphite production workshop, the top of the flue is provided with a water inlet pipe, the bottom of the water inlet pipe is provided with a water outlet pipe, the inside of the flue is provided with a cold water pipe, and one end of the cold water pipe connected to the water inlet pipe, and the other end of the cold water pipe is connected to the water outlet pipe. The beneficial effects of the present invention are: by designing the dust removal tank and the high-pressure nozzle, after the gas enters the dust removal tank, the high-pressure nozzle sprays water mist, the liquid droplets fully contact with the dust-containing gas, and the dust particles are washed and settled to purify the gas. At the same time, it can also remove some gaseous pollutants. It has a simple structure and a reasonable layout. It can handle high-temperature and high-humidity airflow and has high dust removal efficiency.

Description

technical field [0001] The invention belongs to the technical field of graphite production, in particular to a water mist dedusting device for graphite production. Background technique [0002] Graphite is a crystalline form of carbon. Hexagonal crystal system, iron ink color to dark gray. The density is 2.25 g / cm3, the hardness is 1.5, the melting point is 3652°C, and the boiling point is 4827°C. Soft, creamy, and conductive. Chemical properties are inactive, corrosion-resistant, and not easy to react with acids and alkalis. Intensified heat in air or oxygen can burn and generate carbon dioxide. Strong oxidizing agents will oxidize it to organic acids. Used as anti-friction agent and lubricating material, making crucibles, electrodes, dry batteries, pencil leads. High-purity graphite can be used as a neutron moderator in nuclear reactors. Often called charcoal or black lead because it was previously mistaken for lead. Carbon is a very common element that exists in v...

Problems solved by technology

[0003] The graphite production process of the prior art has the following problems: during the production and processing of graphite, a large amount of dust is generated, which pollutes the atmospheric environment, and long-term inhalation of graphite dust can cause graphite pneumoconiosis, which endangers the health of the staff and is difficult to handle
