The petroleum processing, machinery manufacturing, and port logistics industries in Japan are well-developed. The Tokyo Bay Refinery, the surrounding areas of Hokkaido oil fields, and major ports produce approximately 86000 tons of oily sludge annually, with an oil content of 32% -56%, mixed with impurities such as crude oil residue, mechanical oil pollution, and sand particles. Due to its small land area, Japan often uses pyrolysis technology to treat oily sludge, but traditional equipment generally suffers from wall sticking, shortened lifespan, and exhaust pollution problems. According to the Water Resources Protection Law and JIS K 0120 water quality standards, the oil recovery rate of oily sludge must be ≥ 92%, and the oil content of the treated residue must be ≤ 0.3%. Environmental protection requirements are extremely strict.

China Yongle Environmental Protection Engineering has developed the "Japanese standard anti sticking wall type" oily sludge treatment equipment: using a titanium alloy anti-corrosion compartment and a fully enclosed negative pressure pyrolysis structure, it is suitable for complex working conditions in oil fields and refineries, and the core overcomes the pain points of traditional equipment sticking walls. Automatic scraping devices and high-temperature anti sticking coatings are added inside the furnace body, and the service life of the equipment is extended to more than 8 years. Adopting a dual process of "multi-stage screening+anaerobic pyrolysis", 99.4% of sand particles and metal debris are first removed through three-stage precision screening, and then the oil fraction is separated by anaerobic pyrolysis at 550 ℃, with an oil recovery rate of 94.5%. The recovered oil can be refined and used as industrial fuel; The combustible gas produced by pyrolysis consumes 40% of the energy, and the exhaust gas is purified and meets the JIS K 0099 standard. The residual oil content after treatment is ≤ 0.25%, which can be used as building materials.

Adaptation to the entire industry chain scenario: At the Tokyo Bay Refinery, the large centralized equipment has a daily processing capacity of 40 tons and is linked with the plant's fuel supply system to achieve a "sludge oil industrial fuel" cycle. The processing data is uploaded in real-time to the Japanese Ministry of the Environment's regulatory platform; Mobile equipment can be deployed along the operating platform around the Hokkaido oil field, with a daily processing capacity of 18 tons, to avoid the risk of sludge transportation leakage; At Yokohama and Osaka ports, modular equipment with a daily processing capacity of 35 tons is used to clean sludge from oil tankers and prevent ecological pollution in Tokyo Bay and Osaka Bay; In small mechanical processing plants, mini equipment has a daily processing capacity of 4.5 tons, on-site processing of oil and sludge, reducing transportation and storage costs.

Exclusive service guarantee: The equipment has passed JIS certification and dual audits by the Japanese Ministry of Environment and Water Resources Department, successfully adapting to the pyrolysis treatment scenario in Japan. Set up service bases in Tokyo and Osaka, reserve oil resistant and corrosion-resistant spare parts and specialized anti sticking coating materials, and achieve 24-hour maintenance response; Provide Japanese language operation training and process optimization services, equipped with a professional technical team to assist enterprises in solving the pain points of pyrolysis treatment; The equipment procurement cost is only 53% of similar products in Japan, and the income from oil recovery and energy self-sufficiency can cover the investment within 10 months, helping Japan protect the aquatic ecology and overcome the technical difficulties of oily sludge treatment.

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.
