JINLING DRYING

The incineration process currently mainly adopts rotary kiln incineration technology and fluidized bed incineration technology in China. Widely used for incinerating various types of solid, semi-solid or liquid waste, especially suitable for industrial waste and hazardous waste with high moisture content and difficult treatment.

At present, the main treatment methods for household waste, leachate, and sludge are landfill, incineration, and gasification processes. The landfill method poses hidden dangers such as occupying a large amount of land and polluting groundwater, and has been banned by many developed countries; Incineration is currently the mainstream treatment method, but in the process of domestic incineration, sulfur oxides, nitrogen oxides, and fly ash emissions are still generated, and due to the limited combustion temperature, it is difficult to avoid the production of toxic substances such as dioxins. Compared with garbage incineration, garbage gasification technology has a higher reaction temperature, avoiding the production of pollutants such as dioxins, sulfur oxides, and nitrogen oxides. It achieves high-temperature solidification treatment of heavy metals in garbage, effectively avoiding secondary pollution, and is the main development direction of future domestic waste treatment technology.

The treatment of oily sludge remains a challenge both domestically and internationally, and the comprehensive disposal of oily sludge is a pain point in solid waste treatment. Especially in China, the treatment of oily sludge generated from oil extraction, refining, drilling, and other processes has just begun. Currently, there is still a significant gap in the treatment and comprehensive utilization of oily sludge in China compared to foreign levels.

The system consists of sealed feed, dedicated sludge dryer, sealed discharge, exhaust gas treatment and other systems. The system achieves safe operation control by controlling combustible components, temperature, pressure, and oxygen. It has high applicability to sludge containing organic solvents such as oil and is currently one of the safest sludge drying processes in China.
