Tongrui NRY Engine Oil refinery equipment is particularly suitable to regenerate used internal-combustion engine oil including diesel engine oil, gasoline engine oil and used hydraulic oil, other used machinery lubrication oil. NRY series are able to effectively remove colloid, oxid, acid, pitch, particles, impurities, water, gas in the used oil. Specially, NRY can restore the color of used oil and remove the scent rapidly.

Edges of NRY
◆ Two main filtering systems in the NRY which can ensure the NRY works continuously by batch.
◆ Environmentally friendly, no acid used during operation.
◆ The filters in filtering systems are made of stainless steel. It can extend lifetime of filtering systems. Traditional filter is made of fabric or paper which need to be replaced frequently. So using stainless steel filter can largely decrease operation cost for customers.
◆ Exhaust gas removing systems can remove exhaust gas quickly and efficiently and make operation more environmentally friendly.
◆ Heat preservation material which can keep heating high efficient. Reducing operation cost.
◆ Purify blended oils.
◆ Low maintenance and replacement cost.
◆ Low operation cost.
◆ High regeneration rate.
◆ Automatic reverse-washing system will extend the lifetime of filters and improve the performance of the filters.
◆ High performance security system including pressure protection device and automatic temperature controller makes purifier operate safely.
◆ Small size, light weight, low noise.
Working Principle:
Waste oil is pumped into reactor through oil pump, adding certain amounts of flocculant and de-coloring additives into the reactor, mixing and heating. Then with electric-charged particulate becomes big one under the effect of coacervation in waste oil by physical-chemical reacts and sorption effects. At the same time, the gas and the water will be exhaust by the exhaust fan and condenser. After that, the oil enters into high precision strainer to remove off impurities; finally purified oil with regeneration like new oil.
