The heat exchanger chemical cleaning method is based on the principle of dissolution reaction, through the chemical reaction of the cleaning solution with the deposits on the surface of the refining and chemical equipment, and the sundries on the surface of the heat exchanger are cleaned without dismantling the equipment. The entire cleaning process is simple Easy. However, when the chemical cleaning method is used to clean the refining and chemical equipment, if the cleaning solution is not selected scientifically, the performance and quality of the heat exchanger will be damaged during the cleaning process, and the refining and chemical equipment will corrode.
Under normal circumstances, the cleaning solutions used in the cleaning process of the heat exchanger of the refining and chemical equipment are all decontamination detergents. The heat exchanger of the refining and chemical equipment is cleaned with the help of the surface activity of the cleaning solution and the purification chemical reaction. The cleaning methods of refining and chemical equipment mainly include circulation method, dipping method and impact method. Among them, the circulation method is to circulate the cleaning liquid by the action of the pump; the immersion method is to fill the cleaning liquid into the heat exchanger, use the cleaning liquid to clean the heat exchanger for a period of time, and then exchange the cleaning liquid from the heat The bottom of the filter is discharged, and the cleaning liquid is transferred to the mixing equipment. When operators use the immersion method to clean the heat exchanger, they must first understand whether the refining and chemical equipment contains substances that are prone to chemical reactions to avoid damage to the heat exchanger during the cleaning process.
