Description

Technical Field

[0001] The utility model relates to the technical field of surfactant production and processing, and specifically relates to a pipeline structure for surfactant production with a filtering structure. Background Technique

[0002] Surfactants, also known as interfacial active agents, are compounds that can significantly reduce the surface tension or interfacial tension between two liquids, between a liquid and a gas, or between a liquid and a solid. They can be used as detergents, wetting agents, emulsifiers, foaming agents, and dispersants, and are widely used. During the production and processing of surfactants, pipeline structures are needed to facilitate the transportation and transfer of the produced surfactants.

[0003] However, when the pipeline structure for surfactant production is used to transport the produced surfactants, some particulate impurities contained in the surfactants will enter the interior of the transport pipeline along with the flow. During long-term transportation and use, a large amount of impurities will accumulate inside the pipeline and form scale, which will not only block the surfactants transported inside the pipeline, but also be difficult to clean later. There are deficiencies. When the pipeline is used to transport surfactants, it is not convenient to filter the particulate impurities inside the surfactants.

[0004] Now, a new pipeline structure for surfactant production with a filtering structure is proposed to solve the above deficiencies. Content of the Utility Model
