Electric adsorption purification – application in rubber tire industry



Service tradeRubber tire industry
Oil for vulcanizing machine equipment46#Hydraulic oil
Mixing machine oil150~320#Gear oil and aromatic oil
Main pollutantsWater, mechanical impurities (rubber materials, carbon black), oxides (organic acids, alkaline nitrogen))
Purification capacity 1-1.5 t/8 h
Site requirements100㎡

Reasons for the generation of oil pollutants

Sulfurization machine: Water pollution, particulate matter pollution, etc. during long-term use of hydraulic oil
Internal mixer: Oil pollution caused by rubber materials, carbon black, etc. during the rubber mixing and tire manufacturing process.

Hazards caused by oil pollution

  • System lag.
  • The sealing ring is severely worn.
  • The cost of maintenance consumables and labor has increased.
  • Unplanned parking

Solution

Hydraulic system of vulcanizing machine: An electro adsorption online/offline purification system can be used to continuously purify water, mechanical impurities, oxides, etc. generated during the use of oil products.
Sealing oil for internal mixing: The production line for purifying and regenerating sealing oil for internal mixing machine rotors can be used to purify the oil offline, and the purified oil can be returned to the production line for use again.
