Customer profileA large plastic granulation enterprise, with an annual output of 100,000 tons of plastic particles, 8 granulators in the workshop run at the same time, a large amount of high-temperature oil mist (temperature 120 °C) is produced in the process of PE and PP plastic melting processing, the oil mist concentration reaches 1200mg/m³, and contains a small amount of hydrogen chloride corrosive gas, the oil mist is mainly large oil droplets, mixed with some fine oil mist, the high temperature resistance, anti-clogging and separation efficiency of the oil mist collector is extremely high, and it is necessary to achieve the dual goals of efficient purification of oil mist and resource recovery, and meet the requirements of environmental protection compliance.

Core pain points：1. The high-temperature oil mist generated by granulation is easy to damage the seals and filter components of ordinary mechanical collectors, and the equipment failure rate is high, which needs to be stopped for maintenance twice a month, affecting the continuity of production. 2. The high concentration of oil mist is easy to clog the filtration component of ordinary collectors, resulting in a rapid decrease in separation efficiency, and the purification efficiency of traditional mechanical collectors is less than 70% after 3 months of use, which cannot meet the discharge requirements. 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 and clogged components is time-consuming and labor-intensive, and there are potential high temperature safety hazards, increasing labor costs, and waste oil recovery is not timely and can easily cause secondary pollution.

Solution: The high-temperature resistant mechanical oil mist collector is selected, with an air volume of 9000-11000m³/h, which is suitable for high-temperature and high-concentration oil mist treatment scenarios. The equipment adopts high-temperature resistant stainless steel centrifugal impeller and filter assembly, which can be operated stably in a high-temperature environment of 80-150°C for a long time after dynamic balance treatment, and the surface of the impeller and filter assembly is coated with Teflon, which is anti-stick and anti-corrosion, effectively resisting hydrogen chloride gas corrosion and oil mist adhesion, and avoiding clogging. The compound process of "cyclone pre-separation + high-speed centrifugal separation + multi-layer filtration + activated carbon adsorption" is adopted, first through cyclone separation to intercept large oil droplets, and then through the 2900r/min high-speed rotating centrifugal impeller, the fine oil mist particles are thrown to the inner wall for coalescence and separation, and then the remaining fine particles are intercepted through multi-layer high-temperature resistant filter cotton, and finally the residual odor and trace corrosive gas are removed through activated carbon adsorption, equipped with an automatic oil drainage device and an automatic cleaning system for components, to achieve centralized recovery of waste oil and self-cleaning of components. Reduce manual maintenance and install an intelligent temperature monitoring system to avoid damage to equipment due to high temperatures.

Application effect：1. The oil mist purification efficiency reaches 98.3%, the export oil mist concentration ≤ 15mg/m³, and the odor removal rate is 92%, completely solving the problem of oil mist pollution, successfully passing the environmental protection acceptance, and complying with the "Comprehensive Emission Standard for Air Pollutants"; 2. The high-temperature resistance and anti-clogging design greatly improve the stability of the equipment, the monthly equipment failure rate is reduced to less than 0.1 times, the annual loss of downtime and maintenance is reduced by 80,000 yuan, and the service life of the equipment is extended to more than 5 years, without the need to replace components frequently. 3. 14 tons of waste oil are recycled annually, and the annual income reaches 800,000 yuan, realizing resource recycling and reducing oil waste; 4. The automatic cleaning cycle of modules is extended to 30 days, the annual operation and maintenance cost is reduced by 60%, the manual cleaning workload is reduced, the annual labor cost is saved by 60,000 yuan, and the safety hazards of high-temperature cleaning are completely avoided, and the overall economic benefits are remarkable.
