After the organic waste gas is adsorbed and saturated by activated carbon, hot air is used for desorption and regeneration, and the desorbed high-concentration waste gas is evacuated by catalytic combustion. Catalytic combustion uses hot air or hot nitrogen to desorb the high-concentration waste gas produced. The organic waste gas is catalytically oxidized to CO ₂ and H ₂ O between 280-400 °C under the action of a precious metal catalyst, and releases a large amount of heat, which passes through the heat exchanger. Reuse the heat;
Scope of application: Purification treatment of low-concentration organic waste gas.
1. Safety: Safe, stable and reliable, equipped with fire retardant system, explosion-proof pressure relief system, over-temperature alarm system, etc., with long service life;
2. Low energy consumption: When the VOCs concentration reaches 3500mg/m ³, the heating chamber in the purification device does not require auxiliary heating (only 15-30 minutes at start-up), saving energy consumption costs;
3. Intelligence: During the entire operation process of catalytic combustion equipment, fully automated PLC control is realized, which is convenient and reliable;
4. Small footprint: adopting professional design specifications, compact structure, small equipment occupation area, and no impact on normal production;
5. High efficiency: The high-efficiency VOCs exhaust gas purification technology independently developed by Tiandeyi has a purification efficiency of over 97%. It is especially suitable for treating continuously emitted gases. It has a wide range of applications and high VOCs purification efficiency.
It is suitable for furniture spraying, automobile, container, hull, steel structure spraying, enameled wire, printing and other industries.
