Thermal power combustion technology for packaging and printing exhaust gas treatment technology

Packaging and printing are inseparable from our lives, we use textbooks to see novels, mainly paper printing, plastic packaging and printing.

However, a large amount of organic waste gas will be produced during the printing process, mainly including toluene, stupid, ethyl acetate, butyl acetate, solvent oil No. 200, ethanol, butanol and the like produced by the ink solvent in the printing workshop. Pigments, resins, solvents, auxiliary and so on, printing workshop ink exhaust generated mainly in the ink and drying, compounding process, volatile organic solvents is the main source of exhaust gas pollution. Printing ink exhaust composition is complex, heavy smell, flammable, exhaust emissions without purification of the surrounding environment and human health impact.

For the printing ink industry, the characteristics of exhaust gas, we use thermal combustion technology for the above exhaust gas treatment. The typical principle of thermal combustion technology as shown. The VOCs begin to be incinerated. Under the action of heat, VOCs molecules are oxidized to CO2 and H2O. The burnt tail gas has a higher temperature. The heat exchanger is used to replace and reuse the waste heat. The purified exhaust gas is directly emission.

Temperature is a key factor in the thermal incineration process. The combustion temperature is usually controlled above 700 ° C. Most of the organic matter can be oxidized to CO 2 and H 2 O at this temperature, and the removal efficiency can reach more than 95%.

Thermal incineration technology is characterized by thorough oxidation of hydrocarbons can be degraded, there is generally no secondary pollution, easy to operate. However, thermal incineration technology also has some limitations. In the application of thermal incineration technology, it is necessary to first heat the exhaust gas to the required temperature. If the concentration of organic matter in the exhaust gas is high, the heat generated after the combustion of the exhaust gas can be required for the oxidation of the organic matter Of the reaction temperature, the use of exhaust gas combustion method is a viable approach to governance.
