Carbon Industry Related Manufacturing Industries

The carbon industry mainly involves the production and processing of various carbon-based materials, which are widely used in multiple manufacturing fields. Mainly including:

  • Graphite product manufacturing: graphite electrodes, graphite molds, graphite lubricants
  • Carbon fiber and composite material manufacturing: carbon fiber reinforced plastics (CFRP), carbon fiber prepreg, carbon fiber fabric
  • Carbon black manufacturing: rubber and tire industry, plastics and coatings industry, ink and printing industry
  • Silicon carbide and boron carbide manufacturing: refractory materials, abrasives and grinding tools, semiconductor materials
  • Electrode and anode manufacturing: anodes for aluminum electrolysis cells, electrodes for the steel industry, carbon electrodes for the battery industry
  • Activated carbon manufacturing: water treatment and air purification, pharmaceutical and food industries, environmental protection and chemical industries

Wire mesh filter + RTO + post-installed main fan + hot air purge to prevent blockage

(1) Asphalt flue gas pretreatment

Asphalt flue gas is filtered and deoiled before entering RTO, with an oil-gas separation efficiency of up to 90%

Cyclone separator

Wire mesh filter

Rotary valve type RTO

(2) Anti-blocking technology for high-boiling-point copolymers

 

Set up steam heating device for purging (or electric heating)

Considering that a small amount of oily and sticky substances will accumulate on the heat storage bricks during long-term operation of RTO, a high-temperature purge gas pipeline is set up, and the fresh air is regularly preheated to 180℃ with high-temperature air. The oily and sticky substances remaining in the furnace body are evaporated and blown into the oxidation chamber for further decomposition.

(3) Quick replacement technology of heat storage bricks
