What is the thermal oxidator?
Thermal oxidizers are used as a method of controlling pollution for procedural air containing small particles of flammable solids or liquids. Exhaust air in industrial settings can be highly polluted and makes sense to oxidize (burn) as much as possible, so the exhaust consists of a small but non -toxic carbon (soot). Thermal oxidizers are sometimes divided into oxidizers without flames that use slow heating to combust the pollutants and direct thermal oxide flame oxide that uses chocoons of flame. Thermal oxidizers may also include a process called catalytic oxidation. In the catalytic oxidation, organic compounds pass through the supporting material coated with the catalyst, usually noble metal, such as platinum or rhodium, which supports pollutants in the air for burning. Catalytic oxidizers can decompose pollutants at much lower temperatures than thermal oxidizers laather the catalytic effect.It they are regenerative or recuperative.Regenerative thermal oxidizers use ceramic heat transfer beds to obtain as much energy from the oxidation process - often up to 90% to 95%. This bed of heat transfer acts as heat exchangers associated with the retention chamber where organic substances are oxidized. A heat exchanger uses a heat exchanger in the form of a plate, shell or tubes for thermal air with thermal energy from the oxidation process. These systems are less efficient than regenerative thermal oxidizers that only recover about 50% to 75% of generated heat.
One technology used to increase the efficiency of thermal oxidizer is the efficiency of rotor concentrators. The rotor concentrators reduce the total amount of air flowing through the system and increase the concentration of organic substances in the oxidation current. The incoming polluted air flows through the continuous wheel covered with an adsorbent agent.Clean air flows into the atmosphere. The wheel is cleaned by exposure to desorption gas and creates a small, highly concentrated current of organic substances, which can then be effectively oxidized.
The most important parameter for thermal oxidizers and catalytic oxidizers is their destructive efficiency, which usually ranges between 90% and 99%. The higher the efficiency of destruction, the less polluting substances relax into the atmosphere. The common unit for the specification of the efficiency of destruction is in terms of milligrams per cubic meter of volatile organic compounds. Catalytic oxidizers work at 400 to 600 ° F (about 204-316 ° C), thermal oxidizers at 1000 to 1800 ° F (about 538-982 ° C).
