Printing process exhaust gas comprehensive treatment solution


The waste gas component of the printing production workshop is mainly organic waste gas generated by the ink solvent. Paper product printing belongs to low-concentration organic waste gas, and plastic product printing belongs to medium-high concentration organic waste gas. Printing a small amount of ink exhaust gas, the exhaust gas generated by the general ink is mainly non-methane total hydrocarbon organic matter generated by the evaporation of the ink diluent, such as organic waste gas such as toluene, benzene, ethyl acetate, alcohol, etc., and the dust in the ink is mainly carbon black. the Lord. Different treatment processes are adopted according to the difference between the printed product and the used ink. Generally, after the primary exhaust gas is subjected to primary filtration, a photocatalytic oxidation process, a low temperature plasma process, an activated carbon adsorption + CO process, an RTO process or a combination of different processes may be selected.

Process characteristics
(1) Low-concentration exhaust gas adopts a simple process to reduce investment costs;
(2) The high-concentration exhaust gas adopts a combustion process or an adsorption + combustion process, and the removal efficiency is high;
(3) Meet the national environmental emission requirements.
