Device for producing quaternary ammonium salt surfactant
The invention relates to the field of equipment for the chemical industry, in particular to a
device for producing quaternary ammonium salt surfactant.
Quaternary ammonium salt surfactant is a cationic surfactant, which is formed by
replacing all four hydrogen atoms of ammonium cation [NH] with organic groups. It
can be prepared by the reaction of tertiary amine and alkylation agent. The alkylating
agent can be a halogenated hydrocarbon, including methyl chloride,
chloromethylbenzene, etc., or dialkyl sulfate, such as dimethyl sulfate, or alkylene oxide,
such as ethylene oxide. It also can be sulfonate, such as methyl p-toluenesulfonate, etc.
Different quaternary ammonium salt surfactant can be prepared according to above
alkylating agents. Comparing with general ammonium salt, the quaternary ammonium
salt cationic surfactant remaoins stable in alkaline aqueous solution, and release no
amine.
Because surfactants are mostly substances with large foam, high viscosity, and poor
fluidity, stirring them with many foams in general reactors can be very difficult to
perform, and rapid production is difficult to organize. Therefore, large reactors are
generally used for low-speed production with small capacity, long production time and
low production efficiency.
A stirring device is arranged inside the stirring barrel of the existing reaction device for
quaternary ammonium salt surfactant, and the stirring device generally comprises a
stirring shaft driven by a motor, the stirring shaft is arranged at the center of the stirring barrel. There is only the middle stirring shaft rotates in the reaction device with this kind of structure, and the solution in the whole reaction device can only be driven by stirring the solution around the stirring blade, such stirring method provides poor stirring effect and uneven mixing performance, as well as low stirring efficiency. There is obvious layering of the stirred solution, which cannot maintain stable for a desired period of time.
The stirring blade of the conventional stirring device stirs the solution centrifugally,
which makes some of the materials in the solution easy to adhere to the wall of the
device, and the stirring blade can not stir the materials near the side wall very well.
The purpose of the invention is to provide a device for producing quaternary ammonium
salt surfactants. The present invention adds an auxiliary stirring device on the basis of a
conventional stirring device, so that internal liquid is stirred irregularly, and the stirring
effect is better.

wherein a inlet and a first motor are arranged at the top of the reaction tank; an output
shaft of the first motor penetrates through the reaction tank and is connected with a first
connecting shaft which is positioned inside the reaction tank; a stirring blade is arranged
at the bottom of the first connecting shaft; An auxiliary stirring device is provided on the
first connecting shaft and above the stirring blade, and the stirring direction of the
auxiliary stirring device is different from the stirring direction of the stirring blade; The

flow of the solution in the reaction tank. The solution in the reaction tank is stirred
disorderly, so as to prevent the materials in the solution from adhering to the inner wall of
the reaction tank and ensure a good stirring performance. After the reaction of the internal
