Description

Technical Field

[0001] The utility model relates to the field of production and manufacturing, in particular to a low-cost waste gas treatment system. Background Art

[0002] A large amount of VOCs (Volatile Organic Compounds) will be generated during the processing of copper clad laminates. VOCs are harmful to the environment and human body, so they need to be purified into clean gas before they can be discharged. The existing waste gas treatment system usually includes a waste gas treatment device and a waste gas generating device. One waste gas treatment device can treat the waste gas generated by 1 to 4 waste gas generating devices. A factory building usually has 6 to 10 waste gas generating devices and 2 to 3 waste gas treatment devices installed, that is, the waste gas treatment device and the waste gas generating device are designed as 1 to 5 or 1 to 4.

[0003] In actual production, a single exhaust gas generator typically produces only one type of product, and different exhaust gas generators are not used interchangeably. When orders for a particular product type are insufficient, the factory will stop producing the exhaust gas generator for that product. The corresponding exhaust gas treatment device will then be unable to obtain sufficient exhaust gas, necessitating the addition of additional air. This air temperature is generally low, requiring additional fuel to maintain a high temperature in the exhaust gas treatment device's furnace, which undoubtedly increases production costs. Furthermore, if a single exhaust gas treatment device malfunctions, the corresponding exhaust gas generator will cease production, severely impacting production efficiency. Summary of the Invention

That is, the exhaust gas generated by multiple exhaust gas generating devices can be transported to any exhaust gas treatment device under the control of the intelligent control device. In this embodiment, the exhaust gas generating device is an impregnation machine, and the exhaust gas treatment device is an exhaust gas incinerator.
