High Efficiency Rotary Kiln High Temperature Resistant Metallurgical Industry
Overview:
The rotary kiln is the core calcining equipment in industrial production and is widely used in cement, lime, metallurgy and chemical industries. Its high temperature and slow rotation design can ensure that the materials react fully and improve the quality of the finished product. It uses high temperature resistant materials and advanced combustion technology, saves energy and reduces consumption, and adapts to the needs of continuous large-scale production. It is an ideal choice for modern industrial and mining enterprises.

Product Introduction:
This hazardous waste incineration unit is an integral part of the Nanjing integrated production base of Celanese, a Fortune 500 American-owned company. The unit is designed to incinerate various types of chemical waste from the factory, including domestic garbage, hazardous solid waste from eight upstream units, sludge, waste liquid, waste gas, and other categories, totaling nine in all. Once operational, the facility will support the factory's commitment to green production and the principle of zero waste leaving the premises.
The unit's centralized hazardous waste disposal capacity is 12,000 tons/year. The unit additionally generates 6.9 tons/hour of 2.5MPa(G) saturated steam, which is integrated into the factory's pipeline network.
The unit occupies an area of 32 meters by 97 meters and includes various process units such as a waste liquid storage tank area, solid waste pretreatment and conveyance, incineration and waste heat recovery, flue gas rapid cooling, dust removal, desulfurization, and denitrification, ensuring that the incinerated flue gas meets emission standards.
This project reached mechanical completion on September 30, 2020, and completed thermal commissioning, including furnace drying, on November 10, 2020. It officially started production and operation in early December 2020.
Theory:
A rotary kiln’s body is a long and inclined cylinder that rotates to uniformly heat wastes in a high-temperature environment. During waste treating, high-temperature combustion is employed to effectively decompose and process organic materials and other components in waste. The design of the rotary kiln allows waste to stay in a high-temperature environment for a certain duration, ensuring thorough combustion of the waste while effectively dealing with hazardous substances.
Ruiding has independently developed a rotary kiln that combines all the advantages of a traditional rotary kiln incinerator. Significant advancements have been achieved in enhancing heat exchange and ash burnout rates. The incorporation of high-temperature grate technology has elevated the traditional second-stage combustion chamber to a more efficient second-stage furnace, resulting in improved ash burnout rates and a further increase in the incineration efficiency of the rotary kiln.This rotary kiln system is equipped with a chain-type evaporator that addresses the issue of inadequate contact between air and waste in traditional rotary kilns. This optimization enhances waste heat exchange and combustion effectiveness, prevents slag formation inside the kiln, and significantly boosts both combustion efficiency and equipment lifespan. With a high operational uptime, user-friendly maintenance, and suitability for medium to large-capacity processing needs, this rotary kiln solution offers customers an economically viable option for waste treatment.
Ruiding provides customized solutions for hazardous waste by analyzing critical parameters such as elemental composition, calorific value, moisture content, viscosity, ash residue rate, and combustion rate. These tailored solutions are designed to meet the specific needs and characteristics of the waste for each customer.
Advantages:
(1) Ruiding has independently developed a rotary kiln with reliable and safe operation. It is equipped with an advanced feeding system for automatic feeding and ash discharge. The system employs tight sealing measures and maintains a good furnace negative pressure to ensure that harmful gases are not released externally.
(2) The self-developed rotary kiln by the company is also equipped with a Selective Catalytic Reduction (SNCR) system, which efficiently removes NOx generated under high-temperature conditions, effectively preventing atmospheric pollution.
(3) The use of activated carbon adsorption and dual-bag dust removal technology ensures that dioxin emissions fully comply with standards.
(4) The rotary kiln equipment is equipped with an integrated heat recovery device, capable of capturing residual heat and utilizing it through a heat recovery boiler, achieving energy savings, reducing energy consumption, and enhancing the overall thermal efficiency of the system.
R&D and Production:
Ruiding has established the jiangsu province clean incineration resource engineering technology center and the key laboratory of the JICUI-Ruidings joint innovation center.
This laboratory is equipped with advanced detection equipment such as ICP inductively coupled plasma emission spectrometry, atomic absorption spectrophotometry, atomic fluorescence spectrophotometry, high-temperature combustion ion chromatography analyzer, high-temperature combustion rate analyzer, and rapid equilibrium flash point tester. it possesses capabilities for heavy metal analysis, elemental analysis, off-gas calorific value analysis, ash melting point detection, incineration boiler water quality testing, sewage analysis, and volatile waste analysis, etc.
