摘要（英）：

The invention relates to a sulfonation reaction device and an application thereof. The sulfonation reaction device consists of a gas-liquid separating tank, a sulfonation raw material tank, a sulfonation raw material pump, a sulfonator with a cooling and heat-preserving jacket, a horizontal decanter centrifuge, a circulating reflux pump, an aging tank, a neutralizing tank and an extracting tank, wherein the sulfonation raw material pump is connected with the sulfonation raw material tank and the sulfonator; the gas-liquid separating tank is connected with the sulfonator; the circulating reflux pump is arranged on a connecting circulating reflux pipeline in front of the sulfonation raw material pump and behind the horizontal decanter centrifuge; the other end of the sulfonator is connected with the horizontal decanter centrifuge; the aging tank is connected with the sulfonation oil outlet of the horizontal decanter centrifuge; the aging tank is connected with the neutralizing tank and the extracting tank; and the sulfonator is formed by hermetically connecting 2-8 glass tubes or metal tubes which are phi 22-27/phi 8-12 in outer diameter/inner diameter and are 100-500 millimeters in length. According to the sulfonation reaction device, a production process is quick and stable, continuous production is performed, and the tension of an oil-water interface can be below 1*10<-2> mN/m when the concentration of sulfonate is 0.1-0.3 percent.
