[0002] The acrylate production process involves a series of complex chemical reactions, and in these reactions, a large amount of waste gas is generated. The components of acrylate production waste gas are complex and diverse, including a variety of organic compounds, such as unreacted acrylic acid, acrylate monomers, organic solvent vapors, and volatile organic pollutants such as aldehydes and ketones generated during the reaction process.

[0020] 1. For this filtration and purification device for acrylate production, when in use, waste gas is introduced into the purification device. The waste gas is purified by the purification device in cooperation with the treatment liquid inside the purification barrel. After purification, the waste gas moves upward and enters the adsorption device. After the impurities in the waste gas are adsorbed by the adsorption device, the gas enters the preheating device.

At the same time, the driving motor drives the air pipe to rotate, the air pipe drives the air disk to rotate, and the air disk drives the flow distribution pipes to rotate. Then, the waste gas can be discharged from different positions inside the purification barrel through the flow distribution pipes, which is convenient for the waste gas to contact the treatment liquid at different positions, enabling the treatment liquid to be fully utilized.
