Technical Field

[0001] The utility model relates to the technical field of water reducing agent preparation devices, in particular to a water reducing agent sulfonation device. Background Art

[0002] Water reducer is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete. Most of them are anionic surfactants, such as lignin sulfonate, naphthalene sulfonate formaldehyde polymer, etc. After being added to the concrete mixture, it has a dispersing effect on cement particles, which can improve its workability, reduce unit water consumption, improve the fluidity of the concrete mixture or reduce unit cement consumption, thus saving cement.

[0003] Naphthalene water reducer is the mainstream water reducer product on the market. The production of naphthalene water reducer needs to go through the process steps of melting naphthalene, sulfonation, hydrolysis, condensation, neutralization, filtration and drying to obtain the product.

The heat contained in the waste gas is not fully utilized in the reaction process of the sulfonation device, resulting in a waste of resources. Therefore, the utility model proposes a water reducer sulfonation device to solve the shortcomings of the prior art. Utility Model Content
