Graphic Details
Equipment Introduction
This equipment utilizes the excellent heat storage and thermal conductivity properties of ceramics, enabling waste gas to be directly preheated within the ceramic body. Combined with catalysts, it allows complete pyrolysis and oxidation of organic waste gases at lower temperatures, significantly reducing the temperature inside the waste gas incinerator and making the system more energy-efficient and safer.
Main features: The temperature in the combustion chamber ranges from 300-450℃, effectively oxidizing and cracking organic waste gases. The temperature difference between waste gas inlet and outlet is less than 30℃, allowing for direct discharge.
Technical Principles and Processes
This technology achieves waste gas purification through four steps: In the preheating and heat storage stage, waste gas is preheated to 250-400℃ via a regenerative ceramic layer (traditional combustion requires over 800℃); In the catalytic oxidation stage, VOCs react with oxygen to produce carbon dioxide and water under the action of precious metal (e.g., platinum, palladium) or transition metal oxide catalysts, achieving a purification efficiency of 95%-99%; In the thermal energy recovery stage, high-temperature gases recover heat through regenerative ceramics, with thermal energy utilization exceeding 95%; Through intelligent switching of rotary valves, the system enables dual gas path alternating operation, significantly reducing energy consumption.
Technical Advantages
In terms of efficient purification, it can handle complex VOCs such as benzene, ketones, and aldehydes, with a stable purification rate exceeding 95%; In terms of energy conservation and consumption reduction, compared to traditional combustion methods, energy consumption is reduced by 40%-70%, and heat recovery efficiency exceeds 95%; In terms of safety and stability, it features fire prevention, explosion prevention, and over-temperature alarm mechanisms, combined with an automatic control system to ensure stable operation in explosive environments; In terms of waste heat utilization, reaction waste heat can be used for production processes such as drying and heating, achieving cascading energy utilization.
Application Fields
This technology is widely applied in the petrochemical industry (treating VOCs such as alkanes, alkenes, and aromatics), pharmaceutical industry (purifying highly toxic and odorous organic compounds), rubber and latex products (treating sulfur-containing and hydrocarbon waste gases), painting and printing (treating volatile solvents from paints and inks), etc. It is also suitable for industries such as furniture manufacturing, textile printing and dyeing, semiconductors, and synthetic materials.
For waste gas composition and concentration, detailed analysis of waste gas components is required to avoid substances such as sulfur and halogens that can easily poison catalysts. High-concentration waste gases need to be considered for dilution treatment;
Treatment objects: malodorous waste gases, organic waste gases (e.g., waste gases from painting and coating).
Treatment range: 5,000~50,000 Nm²/h
Concentration range of waste gases treated: 50mg/m²~3,000mg/m².
Treatment efficiency: can reach over 98%
Applicable industries: industries generating organic waste gases such as fine chemicals, intermittent painting production lines, printing, light industry, and plastics.
