The printing industry is an indispensable industry in modern society, but in the production process, a large amount of waste gases, such as inks, solvents, etc., will not only cause pollution to the environment, but also cause harm to human health. Therefore, it is very necessary to treat the exhaust gas of the printing industry.
First, the governance plan.
1.Exhaust gas collection.
First of all, it is necessary to collect the exhaust gas in the printing workshop, which can be collected by pipeline to concentrate the waste gas in the treatment equipment.
2.Exhaust gas treatment equipment.
According to the characteristics of the exhaust gas in the printing industry, the following kinds of waste gas treatment equipment can be selected:
1) Activated carbon adsorption device: suitable for the treatment of organic waste gas, activated carbon has a strong adsorption capacity, which can effectively adsorb harmful substances in waste gas.
2) Photocatalytic oxidation equipment: suitable for the treatment of ozone and other harmful substances, photocatalytic oxidation equipment can use the action of ultraviolet lamps and catalysts to decompose ozone into oxygen.
3) Bag filter: It is suitable for the treatment of dust generated in the printing process, and the bag filter can effectively filter the dust and reduce the pollution to the environment.
3.Operational management.
During the operation of exhaust gas treatment equipment, the following points need to be noted:
1) Regularly check the operation of the equipment to ensure the normal operation of the equipment
2) Regularly replace adsorption materials such as activated carbon to ensure that the exhaust gas is effectively treated;
3) Detect the treated exhaust gas to ensure that it meets the emission standards.
4.Third-Party Governance.
For some small and medium-sized printing enterprises, the cost of building their own waste gas treatment facilities is high, and they can choose to entrust it to a professional third-party management company for governance. The third-party treatment company can provide professional waste gas treatment solutions according to the actual situation of the enterprise, and is responsible for the installation, commissioning and operation management of the equipment.
2. Case analysis.
Take a printing enterprise as an example, the enterprise mainly produces printed matter, and a large amount of ink, solvent and other waste gases will be generated in the production process. After comprehensive consideration, the company chose a treatment scheme combining activated carbon adsorption device and bag filter.
Treatment effect: After treatment, the company's exhaust emissions have been effectively controlled, and the air quality has been significantly improved. At the same time, the company's production efficiency has also been improved, saving costs for the company.
Economic benefits: Although the company's governance costs are high, the company's economic benefits have been significantly improved by improving production efficiency and reducing environmental pollution. In addition, the company's brand image has also been enhanced, laying the foundation for the company's long-term development.
3. Summary. Waste gas treatment in the printing industry is an important environmental protection work, which requires the joint efforts of enterprises and society. Through scientific and reasonable treatment schemes, effective operation management, professional third-party management companies and other measures, it can effectively reduce the emission of waste gas in the printing industry, protect the environment and protect human health. At the same time, it can also promote the sustainable development of the printing industry and contribute to the harmony and stability of the society.
