Abstract

The invention relates to a process and a device for continuously preparing powdery washing powder particles. The process provided by the invention is simple in adopted equipment and high in production efficiency. The provided preparation device is simple in structure. The technical scheme is as follows: the process comprises the following steps: (1) a powdery mixture of a neutralizing agent and a wrapping agent and organic-material acid ester enter a high-shearing reactor according to a certain proportion; (2) the formed washing powder particles are output and then enter a flashing dryer; (3) certain particle size is maintained for the obtained washing powder particles; (4) mixed gas flow from an outlet of the flashing dryer enters a cyclone separator for separation; and (5) a finished product is obtained. The device comprises the high-shearing reactor, the flashing dryer, the cyclone separator, a cloth-bag dust remover and an induced draft fan which are communicated in sequence; and the high-shearing reactor is provided with an acid-ester inlet, a powder inlet, an air inlet and a material outlet communicated with the flashing dryer.

Description

technical field

[0001] The invention relates to a manufacturing process of surfactant particles, in particular to a manufacturing process of anionic surfactants. Background technique

[0002] Laundry powder is a granular detergent based on anionic surfactants, which are widely used in daily life. The anionic surfactants are mainly sodium alkylbenzene sulfonate, sodium ethoxylated alkyl sulfate (AES) Sodium alkenyl sulfonate, sodium fatty acid methyl ester sulfonate (MES), etc. The current production process of washing powder mainly adopts high-tower spray drying, that is, surfactants, additives and water are mixed into a slurry with a solid content of about 60%, and then sprayed into fine mist droplets by high-pressure pumps and injectors , and conduct heat transfer with hot air at 200-300°C to dry the droplets into laundry powder particles in a short time.

[0003] The high-tower spray drying process adopts hot air drying at 200-300°C, which consumes a lot of energy; and ...
