Packaging and printing waste gas treatment Printing waste gas treatment
Colorful printing inks and organic chemical diluents are used in the production process of the printing industry. This organic solvent causes a lot of volatile industrial waste gas, with hydrogen chloride, nitrogen dioxide, VOC and other odorous organic waste gas. If the printing waste gas is discharged immediately without disposal, it will cause great harm to the surrounding environment and even the health of the body. Therefore, it is very important for the company to select the appropriate process.
1. UV light striking method: the highly active oxygen UV ultraviolet light is used to directly irradiate the molecular bonds of odorous gas, crack the chemical substances of odorous gas, reuse the highly active oxygen UV ultraviolet light to dissolve the oxygen atoms in the air, generate active oxygen, and converge with the pollutant molecules in the state of free ions to create harmless or low harmful chemicals, so as to achieve the purification treatment effect;
2. Secondary spraying+plasma oil fume purifier: use the form of two-stage spraying to remove the fine particles and vegetable oil in the organic waste gas by spraying, and then use the plasma purification technology to remove the malodorous gas, discharge CO2, H2O and other harmless chemicals, in addition to causing a lot of negative air ions.
3. Adsorption method: use activated carbon to adsorb hazardous components in organic waste gas horizontally.
4. Catalytic combustion method: use metal catalyst to reduce combustion temperature, accelerate the thorough air oxidation of toxic gas, and achieve the effect of purification treatment.
5. Low temperature plasma method: under the action of external electric field, it is a safe chemical substance that can transform complex biological macromolecular pollutants into simple small molecule water.
How to prolong the service life of waste gas treatment equipment for environmental protection packaging and printing?
At this stage, with the rapid development of society, there are various environmental waste gas treatment equipment. However, how long can a set of environmental protection equipment for organic waste gas treatment be used? How to prolong the service life of organic waste gas treatment, environmental protection, packaging and printing waste gas treatment equipment?
Companies that assemble organic waste gas treatment equipment must standardize the use of organic waste gas treatment equipment. They can't ignore it and let the environmental pollution and industrial waste gas spread to the steam immediately. The selection of industrial waste gas machinery and equipment should also take into account the cost and practical value. Do not replace parts for the second half of the daily maintenance of the organic waste gas treatment equipment. The equipment is made of metal materials and can operate normally for at least 5-6 years.
In order to reduce the maintenance cost of the organic waste gas treatment equipment in the later period, we must learn the training preventive measures: in order to avoid the function of the mechanical equipment, reduce the zero point of the measurement accuracy or reduce the problems, the maintenance plan is carried out according to the theme activities of the predefined activities. Professional knowledge and skills are called the preventive maintenance of mechanical equipment. What is the preventive maintenance method commonly used around the world.
Considering the situation of skill assessment in operation process, monitoring and maintenance of skill assessment in operation process is a preventive maintenance method, which should be the basis of quantitative analysis method for skill assessment in operation process of organic waste gas treatment equipment. In general, this kind of equipment often needs routine maintenance and regular maintenance to master the professional ability of the equipment. In view of the deterioration level of various parts of mechanical equipment, preventive maintenance shall be carried out in time before the problems occur, and the common failure risk of mechanical packaging printing waste gas treatment equipment shall be eliminated, as well as the maintenance performance and precision.
