How to deal with waste gas from packaging and printing?
VOCs industrial waste gases are characterized by many sources, types, complex components and large consumption, which makes it very difficult to operate. Harmfulness of industrial waste gas: Generally speaking, people are not aware of the harm caused by organic waste gas, or they are lucky to be free of the harm caused by waste gas. But in fact, the damage to the body caused by the discharge of industrial waste gas belongs to "silent moistening".
Printing technology mainly includes offset printing, screen printing, gravure printing and hole printing. VOCs of differential printing technology come from the same source and discharge method: VOCs come from the printing ink and paint thinner used (paint thinner is required for packaging and printing sultry substrate, such as metal printing and plastic printing), composite adhesive and equipment cleaner. The discharge methods of the feasibility include: organic solvent evaporation in the whole process of printing ink preparation, ink solvent evaporation in the printing process, drying process Combine the whole process and equipment cleaning process.

The catalytic reaction air purification device is usually an air purification device that uses metal catalysts to adjust the reaction conditions so as to remove organics at a relatively low standard. The essence of the gas-solid catalytic reaction speed in the catalytic reaction air purification device is that ozone participates in deep air oxidation. Precious metal catalysts are selected to reduce the reaction activation energy of substances in organic waste gas and O2, so that organic compounds can be oxidized to form CO2 and H2O in sufficient air at a relatively low ambient temperature of 250~350 ℃, which belongs to flameless combustion and will not produce secondary pollution during the whole operation process.
Treatment of waste gas from packaging and printing
The organic waste gas in the printing industry comes from the evaporation of printing ink, xylene, xylene, automotive gasoline, ethanol and other solvents used in the printing process. The organic waste gas is a kind of combustible gas with complex composition and heavy odor. If the organic waste gas is discharged into the air immediately without purification, it will have a great impact on the surrounding environment,
Attention should be paid to the energy conservation and emission reduction of VOCs from the source control, the upgrading and transformation of production process, the end treatment and the plant design scheme. Only by finding the source of environmental pollution and doing a good job in prevention, can the environmental pollution problem be reduced from the source, and it is also closely related to the types of materials in the packaging and printing process, and the implementation and control of enterprise management.
Basic principle of RCO catalytic combustion device for packaging and printing waste gas treatment:
The precious metal catalyst is used to reduce the activation energy of the reaction between substances in the organic waste gas and O2 in the packaging and printing waste gas treatment RCO, so that the organic compounds can also be oxidized to form CO2 and H2O with sufficient air at a relatively low ambient temperature of 250~350 ℃, which belongs to flameless combustion. The high-temperature oxidation gas is discharged after indirect heat transfer according to the heat exchanger and the new organic waste gas, which is mainly used to solve the high concentration organic waste gas adsorbed by the absorbent regeneration.
It is committed to continuously in-depth understanding of the situation in the fields of packaging and printing, painting, printing and dyeing plants, electronic devices, plastics, furniture, oil refineries, plastics, chemical plants, paper industry, leather products, fertilizer, pharmaceutical industry, food industry, and other fields of odor and organic waste gas cleaning solutions.
