Embodiment Construction

[0016] The present invention provides a method for removing voc from acrylic emulsion and its device. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] The present invention provides a kind of acrylic acid emulsion voc detachment method, wherein, described method step is:

[0018] A. Preheat the crude extract of acrylic acid emulsion. The voc removal method of the present invention mainly uses the principle of interaction between the mixed gas in the evaporator and the acrylic emulsion so that the volatile organic compounds are stripped from the emulsion. In order to ensure that the acrylic emulsion has a higher voc removal efficiency in the evaporator, it is necessary to use The crude extract of t...

Abstract

The invention discloses an acrylic emulsion voc (volatile organic compounds) removal method and a device therefor. The method comprises the steps of preheating an acrylic emulsion crude extract, introducing the preheated acrylic emulsion crude extract into an evaporator, and meanwhile, introducing mixed gas of water vapor and inert gas into the evaporator for voc removal, thereby preparing the acrylic emulsion finished product. By the method, the content of voc in the acrylic emulsion crude extract can be greatly lowered, and the quality of the product is greatly improved, so that the product can fully meet environment-friendly requirements; and the method is low in operation cost and high in voc removal efficiency and has little damage to the product high polymer, so that the quality of the product cannot be affected.

Description

technical field [0001] The invention relates to the technical field of polymer separation, in particular to an acrylic emulsion VOC detachment method and a device thereof. Background technique [0002] The voc (volatile organic compounds) in the acrylic acid products obtained by the current acrylic emulsion system is still high, which does not conform to the trend of green and environmental protection technology development. The detachment process is not only costly and time-consuming, but also the detachment effect is not ideal, which greatly limits the development of high-quality acrylic products. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above deficiencies in the prior art, the object of the present invention is to provide a method and device for removing voc from acrylic emulsion, aiming at solving the problem of excessive voc content in current acrylic emulsion products. [0005] Tec...
