Description

Heating type anti-fouling fatty acid catcher Technical Field The utility model relates to the technical field of grease processing equipment, in particular to a heating type anti-fouling fatty acid catcher. Background In the deodorization process of oil refining, high-temperature steam carries a large amount of fatty acid steam into a trap, and the fatty acid steam needs to be converted into a liquid state through a condensation technology to realize the trapping of fatty acid. However, conventional traps present a significant technical bottleneck in the actual operation. Firstly, fatty acid steam is easy to solidify and adhere to the surface of the filler layer due to condensation and temperature reduction in the condensation process, so that scale deposit is formed, especially on the surface of the filler and the inner wall of a condensation pipe. Accumulation of scale not only greatly reduces heat transfer efficiency, but also causes gradual attenuation of trapping efficiency, increases gas flow resistance, and influences stability of a vacuum system. Secondly, the conventional trash cleaning process of the catcher is complex and high in cost, equipment is required to be detached regularly and the catcher is cleaned by a high-pressure water gun or a chemical solvent, so that time and labor are consumed, and environmental risks are increased due to treatment of chemical waste liquid. Especially under the working condition of high-viscosity fatty acid or low temperature, the fouling phenomenon is more serious, and the production efficiency is severely restricted. With the rising requirements of the food industry for energy efficiency, environmental protection and automation, there is a need for a new trapping device that can actively regulate temperature and inhibit scale formation during the trapping phase while maintaining efficient mass transfer. Disclosure of utility model The utility model aims to solve the problem of providing a heating type anti-fouling fatty acid catcher, which can improve the catching efficiency of fatty acid, improve the anti-fouling performance and reduce the cleaning and maintenance cost.
