Customer profileA large plastic granulation enterprise, with an annual output of 100,000 tons of plastic pellets, 8 granulators in the workshop run at the same time, a large amount of high-temperature oil mist (temperature 120 °C) is produced during the melting processing of PE and PP plastics, the oil mist concentration reaches 1200mg/m³, and contains a small amount of hydrogen chloride corrosive gas, which requires extremely high temperature resistance and corrosion resistance of the purifier, and needs to achieve the dual goals of efficient oil mist purification and resource recovery.

Core pain points：1. The high-temperature oil mist generated by granulation is easy to damage the seals and electric field modules of ordinary purifiers, and the equipment failure rate is high, and it needs to be stopped for maintenance twice a month, affecting the continuity of production. 2. The corrosive gas contained in the oil mist is easy to corrode the purifier plate, resulting in a rapid decrease in purification efficiency, and the purification efficiency of the traditional purifier is less than 70% after 3 months of use; 3. High-concentration oil mist is emitted unorganized, polluting the workshop and surrounding environment, high environmental compliance pressure, and serious oil mist waste, with an annual loss of about 15 tons of unrecycled waste oil. 4. Manual cleaning of oil mist pollutants is time-consuming and labor-intensive, and there are potential safety hazards, increasing labor costs.

Solution: Select high-temperature and corrosion-resistant electrostatic oil mist purifier, treat air volume of 9000-11000m³/h, suitable for high-temperature and high-concentration oil mist treatment scenarios. The equipment adopts 95# ceramic high-temperature electric field insulation material, which can operate stably in a high-temperature environment of 80-150°C for a long time, and the plate is coated with Hastelloy, which has a corrosion resistance life of ≥ 5 years, effectively resisting hydrogen chloride gas corrosion. The compound process of "pre-filtration + electrostatic adsorption + activated carbon adsorption" is adopted, which first intercepts large oil droplets and impurities, and then captures fine oil mist particles through high-pressure static electricity, and finally removes VOCs and corrosive odors.

Application effect：1. The oil mist purification efficiency reaches 98.5%, the outlet oil mist concentration ≤ 15mg/m³, and the VOCs removal rate is 92%, which completely solves the problem of oil mist pollution and successfully passes the environmental protection acceptance. 2. The high-temperature and corrosion-resistant design greatly improves the stability of the equipment, the monthly equipment failure rate is reduced to less than 0.1 times, the annual downtime and maintenance loss is reduced by 80,000 yuan, and the service life of the equipment is extended to more than 5 years; 3. 14 tons of waste oil are recycled annually, which can be recycled after treatment, with an annual income of 800,000 yuan, realizing resource recycling; 4. The automatic cleaning cycle of the plate is extended to 30 days, the annual operation and maintenance cost is reduced by 60%, the manual cleaning workload is reduced, and the annual labor cost is saved by 60,000 yuan, and the overall economic benefits are remarkable.
