[0002] The acrylic acid online mixing system is a supporting equipment for mixing acrylic acid and water. At present, the domestic acrylic acid mixing generally adopts the method of injecting acrylic acid into the acrylic acid storage tank, measuring the amount of acrylic acid injected, calculating the amount of water to be added according to the concentration, and then adding water into the acrylic acid storage tank. Subsequently, a circulating pump is used to circulate the water and acrylic acid through the circulation to mix. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of the acrylic acid online mixing system.

[0003] The existing online acrylic acid mixing system has certain drawbacks when in use. During the mixing process, if the production needs to use the prepared acrylic acid, it can only wait.

When mixing, the temperature of the pipeline is too high or too low, which can easily cause a certain impact on the liquid. In view of the defects of acrylic acid mixing, the acrylic acid mixing is optimized and modified. To this end, we propose an online acrylic acid mixing system. Utility Model Content
