Microwave High-Temperature Carbonization for Impurity Removal in Organic Materials

Microwave high-temperature carbonization and impurity removal for organic-containing materials demonstrates significant advantages with microwave kilns

I. Characteristics of Microwave Impurity Removal Technology:

Microwave technology employs high-temperature carbonization to remove impurities from solid waste containing organic matter. Utilizing microwave's penetrating heating, internal molecular friction for temperature rise, overall heating, and selective heating of materials with high dielectric constant, it enables instant high-temperature catalytic heating. Under specific atmospheric conditions, organic matter rapidly decomposes, achieving carbonization of impurities. This thermal process breaks down large molecular chain organic compounds into smaller, more manageable compounds, combustible gases, oils, carbon black, etc. It effectively removes organic impurities from solid materials, achieving reduction and harmless treatment, while allowing partial resource recovery. Applications include diamond micropowder, alumina residue, kaolin residue, quartz sand powder, and removal of organic impurities from hazardous solid waste.

II. Microwave Heating Principle and Advantages of Microwave Technology:

Microwave high-temperature impurity removal kilns utilize the material's own dielectric properties (powder, granules, blocks, sheets, columns, etc.). Under the influence of a high-frequency electromagnetic field, polar molecules realign according to the field's polarity, transitioning from random distribution to ordered orientation. This rapid realignment generates intense friction, producing heat. In this microscopic process, microwave energy converts into thermal energy within the material, resulting in macroscopic temperature rise—this is the fundamental principle of microwave internal heating. In contrast, conventional coal, electricity, oil, or gas kilns have high energy consumption, pollution, and exhaust emissions. Their heating method involves external heat conduction, from surface to interior, requiring prolonged heating time, low thermal efficiency, high energy consumption, and prone to coking, necessitating regular furnace cleaning, shutdown maintenance, and frequent component replacement. 

Microwave technology offers energy savings (high thermal conversion efficiency, over 30% more energy-efficient than traditional heating), environmental friendliness (no external emissions, effectively reducing harmful substances), cleanliness (materials absorb microwave energy and heat themselves, contact-free and pollution-free, improving product quality and yield), and high thermal efficiency (rapid heating, high energy utilization). Additionally, microwave industrial equipment manufactured by Zhongsheng operates at temperatures up to 1600°C, with kiln temperature stability within ±5°C, high automation, effectively reducing manual labor and environmental impact.

III. Industry Advantages of Zhongsheng Thermal Energy Microwave Kiln Equipment:

Yueyang Zhongsheng Thermal Energy Co., Ltd., established in 2011 with registered capital of 12 million RMB, specializes in the R&D, application, and equipment integration of microwave thermal technology for industrial use. The company designs, manufactures, and sells microwave equipment, primarily producing microwave experimental furnaces for enterprises and research institutions, as well as custom microwave industrial equipment. In the field of microwave applications, it holds 12 unique invention patents and 57 utility model patents. Its microwave heating kiln technology was included in the National Development and Reform Commission's fifth batch of key energy-saving technology promotion catalog. Compared to low-power household microwaves, Zhongsheng's industrial microwave equipment meets the demands of continuous operation, stable production, and durability in industrial settings. It features professionally configured 1.5KW industrial-grade microwave sources with continuously adjustable power, ensuring uniform, adjustable, and controllable furnace temperature. Designed for 24/7 operation, it uses proprietary crack antenna energy feed devices to ensure uniform microwave fields and prevent microwave reflection damage to magnetrons, allowing uninterrupted use and online replacement of wear parts without affecting production. Additionally, it employs unique microwave leakage prevention devices: microwave leakage does not exceed 1mW/cm² (national standard is ≤5mW/cm²), enhancing production safety, whereas other manufacturers typically only meet national standards. Zhongsheng's microwave drying equipment, microwave experimental furnaces, microwave high-temperature bell kilns, microwave high-temperature push plate kilns, microwave high-temperature roller kilns, and microwave pyrolysis kilns all have successful application cases.
