Exhaust gas recovery device and exhaust gas recovery system for processing copper-clad plate

Abstract

The invention discloses an exhaust gas recovery device for processing a copper-clad plate. The exhaust gas recovery device comprises an absorption tower body. A spray absorbing section, a packing absorbing section, an air foam removing section and an exhaust gas emission section are sequentially arranged inside the absorption tower body from bottom to top. The spray absorbing section comprises a spray thrower, a liquid storage tank placed below the spray thrower, and a liquid cooler placed inside the liquid storage tank. According to the exhaust gas recovery device for processing the copper-clad plate, due to the fact that the liquid cooler is additionally arranged in the liquid storage tank of an absorption tower, the liquid for absorbing the exhaust gas of organic solvents such as DMF and acetone is cooled. Therefore, the absorbing speed of the circulation liquid to the organic solvents in the circulation process of the liquid is increased, the absorbed dose of the organic solvents such as the DMF and the acetone by the circulation water with the same weight is also increased, and the amount of water in the absorbing process of the exhaust gas is reduced. The invention further provides an exhaust gas recovery system for processing the copper-clad plate, wherein the exhaust gas recovery system for processing the copper-clad plate comprises the exhaust gas recovery device for processing the copper-clad plate.

Description

technical field [0001] The invention relates to the field of copper-clad laminate processing equipment, in particular to an exhaust gas recovery device for copper-clad laminate processing and an exhaust gas recovery system including the device. Background technique [0002] At present, in the copper clad laminate processing industry, a large amount of waste gas containing organic solvents such as DMF (dimethylformamide) and acetone will be generated during the dipping and drying process. Direct discharge will not only pollute the environment, but also affect human health, and waste raw materials, It will also increase the production cost of copper clad laminates and cause huge waste to enterprises. [0003] There are traditionally two treatment methods for a large amount of waste gas containing DMF, acetone and other organic solvents generated during the dipping and drying process. The first method is to send the organic solvent waste gas into the waste gas incinerator to b...
