With perfect industrial system and developed oil and gas storage and transportation, oil refining and processing, machinery manufacturing, port storage, automobile maintenance and other industries in Japan, a large amount of oily sludge is produced every year. This kind of waste belongs to HW08 hazardous waste, which is listed as the key control object by the Ministry of Environment in Japan, with extremely strict disposal standards. In accordance with the Waste Treatment Law and the Law on Countermeasures for Soil Pollution, Japan clearly requires that the oil content of the residue after the treatment of oily sludge shall not be higher than 0.3%. Wastewater must be recycled or discharged in accordance with the standard. It is strictly prohibited that the oil pollution permeates into the soil, pollutes groundwater and rivers. Enterprises will face huge fines, production bans and even legal liabilities if they dispose in violation of the rules. Traditional oily sludge treatment adopts flocculation sedimentation, centrifugal separation and other processes, which has problems such as low oil recovery rate and difficult to meet the standard of residual oil. Although the incineration method can achieve thorough reduction, it is difficult to meet the increasingly strict environmental protection requirements of Japan due to serious resource waste and easy secondary pollution.

In the field of hazardous waste treatment, Yongle Group, based on the characteristics of oily sludge in Japan and strict disposal standards, jointly developed with local environmental protection agencies in Japan, launched customized oily sludge pyrolysis treatment system in Japan, providing a breakthrough solution for industrial sludge disposal in Japan. The equipment strictly follows the hazardous waste disposal standard of Japanese environmental protection province and passes the local environmental protection certification of Japan. It adopts the combined process of three-stage screening, negative pressure pyrolysis and oil-water separation to remove the sand and metal impurities in the sludge, and then through the 400-500 ℃ oxygen-free pyrolysis technology, it realizes the three-phase efficient separation of oil, water and slag, with oil recovery rate of over 95%. The recovered oil has high purity, which can be directly sent back to the refinery for refining or used as industrial fuel to realize resource recovery and reutilization. After treatment, the oil content of the residue is less than 0.2%, which is non-toxic and harmless. It can be safely landfilled or used for soil improvement, completely complying with the disposal standard of Japan.

The whole equipment is made of anti-corrosion and anti-sticking materials, which can withstand the corrosion of oily sludge, avoid sludge wall blocking, operate stably and reliably, and have a long service life. It is suitable for various complicated sludge scenarios in Japan. Whether it is the bottom sludge of refinery tank, the sludge produced by mechanical processing, or the oil sludge from port and airport ground service, it can be effectively disposed. The equipment is equipped with an intelligent monitoring system to monitor the operating parameters and emission indicators in real time to ensure that the whole process meets the standards. The disposal data can be automatically stored and exported for the convenience of verification by the environmental protection department; Combustible gas generated in pyrolysis process can be reused for equipment heating to realize energy self-circulation. Its operation cost is reduced by 50% compared with traditional process, greatly reducing the operation burden of enterprises and perfectly meeting the demands of Japanese enterprises on "cost reduction and efficiency improvement, compliance and environmental protection".

At present, the oily sludge treatment equipment of China Yongle Group has been put into use in such industrial bases as Yokohama, Nagoya and Kobe, assisting Japanese refining and machinery manufacturing enterprises in achieving compliance disposal of oily sludge, eliminating water and soil pollution, reducing environmental risks, and at the same time achieving economic benefit increase through oil recycling, truly achieving environmental protection and benefit win-win. China Yongle Group provides one-stop services such as equipment installation, Japanese operation training, regular maintenance and compliance consultation. Core accessories can be purchased and replaced in Japan. After-sales response is timely to ensure stable operation of equipment. In the future, China Yongle Group will continue to deepen the cooperation with Japanese enterprises, optimize equipment performance, help Japanese industrial hazardous waste treatment develop towards a more efficient, low-carbon and resource-based direction, and make China's contributions to Japanese ecological environment protection.

Yongle Environmental Protection is mainly engaged in the research and development, production and sales of complete sets of technical equipment for organic solid waste disposal and comprehensive utilization. Production and manufacturing, domestic waste treatment equipment, tire pyrolysis equipment, medical waste disposal equipment, hazardous waste disposal equipment, and achieve efficient and comprehensive utilization of resources through independently developed low-temperature anaerobic pyrolysis equipment technology solutions.
