RCO catalytic combustion device

Overview of catalytic combustion treatment technology for RCO
    Catalytic combustion due to the ignition temperature is low, is an ideal catalyst by catalytic reaction (flame) method for treatment of organic pollutants and has wide application range, simple structure, high purification efficiency, the advantages of energy saving, no two pollution, has been widely used at home and abroad.
    I developed the company catalytic combustion purification device has the advantages of simple operation, high degree of automation, can effectively deal with all kinds of organic waste gas pollutants, the concentration of 10g/m is less than or equal to fand, welcomed by the majority of customers.
    Catalytic combustion treatment technology, structure and principle, catalytic combustion purification device is mainly composed of flame arrester, heat exchanger, catalytic reaction bed, fan these main components

Principle of RCO catalytic combustion treatment technology

   Compared with direct combustion, catalytic combustion temperature is lower and combustion is more complete. The catalyst used for the catalytic combustion (change catalyst does not change the chemical balance, the original is only the speed of chemical reaction, and after reaction. The properties of the catalyst itself does not change) for noble metal and metal oxide with large specific surface. Catalytic combustion is the removal of organic pollutants. Under the action of catalyst platinum and palladium, it can oxidize organic pollutants in waste gas into carbon dioxide and water at lower temperature.

    he gas flame arrester after filtration through the synchronous reverse switching valve, by-pass valve into the main regulator into the heat exchanger, the heat exchanger heat increased after a certain temperature into the preheating chamber, after heating the preheating chamber, the exhaust gas temperature to the catalytic ignition temperature (~ 250 degrees), and then into the catalytic reaction in the bed. The activity of catalyst, oxidation reaction of organic waste harmless water and carbon dioxide, and release a certain amount of heat. After reaction, the high temperature gas enters the heat exchanger again, and finally enters the atmosphere at lower temperature by the draft fan.

    With the help of the catalytic combustion catalyst at low temperature (200 to 400 DEG C), complete oxidation of organic matter, therefore, the operation is simple, safe, high purification efficiency, especially in organic waste recycling organic waste gas purification value is widely used.

    Different emission occasions and different exhaust gases have different process flows. But no matter which process is adopted, it is made up of the following process units.

(1) Exhaust gas pretreatment
(2) Preheating device
(3) Catalytic combustion system

 

Process flow diagram

Catalytic combustion performance characteristics of RCO

(1)With high-quality metal platinum and palladium plating on honeycomb ceramic carrier as catalyst, the purification efficiency is as high as 97-100%, the equipment life is long, and renewable, gas flowing, small resistance.

(2)Complete safety facilities: fire protection dust collector, pressure relief hole, overheating alarm and other protection facilities.

(3)Preheat 15~30 minutes, full power heating. When working, only the fan power can be consumed. When the exhaust gas concentration is low, automatic intermittent compensation heating.

(4)The waste heat can be returned to the drying channel for drying, reducing the power consumption in the original drying channel, and also for other aspects of the plant heat recovery.

Selection of equipment for RCO catalytic combustion treatment and matters needing attention

(1)Exhaust gases should not contain the following substances: oils with high viscosity. Such as phosphorus, bismuth, arsenic, antimony, mercury, lead and tin; high concentrations of dust.

(2)When selecting the equipment, indicate the composition, concentration and outlet temperature of the exhaust gas.

(3)Equipment installation site, no corrosive gas, and have good rainproof measures.

(4)The power supply for the equipment is three-phase AC 380V, frequency 50Hz.

(5)Indicate whether there are special requirements

Applicable range of catalytic combustion of RCO

(1)For the purification of organic solvents, such as benzene, alcohols, esters, phenols, ethers, alkanes and other mixed organic waste gases.

(2)Apply to enamel wire, machinery, motor, chemicals, instruments, automobiles, engines, plastics, electrical appliances and other industries in the purification of organic waste gas.

(3)Suitable for drying oven, printing ink, motor insulation, drying line, etc..
