Advanced Solution of VOCs Treatment in Coating Industry to Save Energy Consumption

The coating industry refers to the industrial field of coating treatment on the surface of objects, which is widely used in automobile manufacturing, aerospace, shipbuilding and other industries. Common coating methods are: spraying, dipping coating, rolling/brushing, electrostatic spraying, electrophoretic deposition.

In the coating production process, volatile organic compounds (VOCs), dust, nitrogen oxides and other waste gases are usually produced. With the increasingly strict and perfect environmental protection laws and regulations, the standards and regulatory requirements for industrial waste gas emissions are also constantly improving. Companies are under increasing pressure not only to ensure that their emissions meet the latest environmental standards, but also to consider how to optimize treatment equipment to reduce energy consumption and achieve a balance between economic efficiency and environmental protection.

The Megaunity focuses on technological innovation to help companies achieve more stringent VOCs emission standards while effectively saving energy consumption during the operation of processing equipment. Actively exploring effective ways to implement recoverable heat in the exhaust gas not only reduces the need for external energy but also reduces overall operating costs.

Energy-saving VOCs governance measures

1. High concentration waste gas treatment:

Technical application: For exhaust gas containing higher concentrations of VOCs, particulate matter and other impurities are first removed through a pretreatment step, and then directly sent to a regenerative oxidation process (RTO) for efficient purification.

Waste heat recovery: The high-temperature gas generated during the RTO process passes through a special heat storage body, and this part of the heat can be reused to preheat the subsequent organic waste gas, thereby saving the fuel consumption of waste gas heating, and the heat recovery efficiency is ≥ 95%.

Compared with the traditional catalytic oxidation and direct combustion oxidation TO, it has the characteristics of high thermal efficiency and low operating cost. When the concentration is slightly higher, secondary waste heat recovery can also be carried out, which greatly reduces production and operating costs.

2. Large air volume and low concentration waste gas treatment:

Technical combination: When the paint produces large air volume and low concentration VOCs exhaust gas, the zeolite runner concentration device is used to concentrate the VOCs to a higher concentration, and then introduced into the RTO for thorough oxidation and decomposition.

Effect improvement: This combined process can effectively improve processing efficiency and reduce overall operating costs, while ensuring a very high purification rate.

3. Water-based paint waste gas treatment:

Washing absorption: for low concentration VOCs waste gas generated from water-based paint spraying and other processes, a washing tower is adopted to absorb harmful substances.

Economical and environmentally friendly: This method is easy to operate and relatively low maintenance costs, especially suitable for companies that are sensitive to initial investment but want to achieve good governance results.

4. Comprehensive energy-saving solutions:

Waste heat reuse: the treatment scheme is equipped with advanced waste heat recovery unit. These systems can convert the waste heat generated in the process into valuable resources, such as preheating the fresh air entering the oven, thereby reducing the energy consumption of the entire production process.

Intelligent control system: Combined with modern information technology, an intelligent monitoring and management system is established to dynamically adjust the working status of the equipment according to actual needs to further optimize energy consumption performance.

By implementing these comprehensive energy efficiency and emission reduction strategies, Megaunity can not only help customers easily meet current and future environmental regulations, but also significantly reduce their long-term operating costs and help companies go further on the road to sustainable development.
