Problems solved by technology
[0009] Relatively speaking, more waste gas is produced during the production and spraying of water-based coatings. Most of the gases produced during the process are ammonia and alcohol. Activated carbon has a weaker adsorption capacity for these components. In addition, In order to increase the production speed, waste gas treatment needs to be treated in a flowing manner, and with the acceleration of the gas flow rate, the adsorption capacity of activated carbon is weaker, and even the adsorption effect cannot be exerted, so it is not suitable to treat waste gas by activated carbon adsorption

Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation examples, so as to clearly understand the technical solution of the present invention.
[0032] like figure 1 As shown, the waste gas treatment system of the present invention includes a waste gas collection unit, a filter unit, an exchange unit, and an exhaust unit.
[0033] The waste gas collection unit includes a plurality of waste gas pipes 11 arranged side by side, respectively connected to the pipes of the equipment producing waste gas during the construction of the water-based paint and the waste gas main pipe 12, and the waste gas is transported to the filter unit by the waste gas main pipe.
[0034] The filtering unit includes a spraying device 21, a circulating pool 22, a filter screen 23 and a water circulating pipe 24a. The spraying device 21 is placed on the top, and the circulating pool 22 is placed at the bottom. ...

The invention discloses a waste gas treatment system in the process of constructing a water-based coating. The system comprises a water gas collection unit, a filtering unit, an exchange unit and an exhaust unit, wherein the water gas collection unit conveys waste gas to the exchange unit to filter out water-based gas impurities, and the exhaust unit exhausts clean waste gas. The waste gas is subjected to double filtration through the exchange unit, most of water-soluble impurity gas in the waste gas is dissolved in water, and clean gas is exhausted finally, so that the system is environment-friendly, low in cost and high in efficiency; and the water is recycled in the filtering process, so that the cost is low.
Description
[0001] technical field [0002] The invention relates to a waste gas treatment system, in particular to a waste gas treatment system suitable for the construction process of water-based paint. [0003] Background technique [0004] Industrial coatings are chemical mixed coatings that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. It has the functions of anticorrosion and decorative appearance, and is an indispensable fine chemical product in modern industry. [0005] Most traditional paints use organic solvents as solvents and thinners, so they are called oil-based paints. During the baking process, organic solvent volatiles such as xylene and trimethylbenzene will be produced. These organic volatiles are harmful and toxic, and they have a great impact on the health of on-site workers and the surrounding environment. The country is also taking measures to Measures to gradually limit the use of oil-based paints, whil...
