Abstract

The invention is suitable for the technical field of energy, and provides a prediction method and device for scaling maintenance in an evaporator. The method comprises the steps: obtaining a scaling heat flow model of the evaporator; according to the measurement data of the evaporator, obtaining a heat change model corresponding to the energy change amount of the evaporator; obtaining the scalingthickness of the evaporator according to the scaling heat flow model and the heat change model; and obtaining the descaling maintenance time according to the scaling thickness. After the descaling maintenance time is obtained, advanced planning or early warning work can be conducted on evaporator descaling, a worker can monitor the scaling situation in real time in a simple and rapid mode, unnecessary shutdown manual detection steps are reduced, and waste of manpower and material resources caused by too frequent descaling is reduced; meanwhile, the influence of too late descaling on the heat efficiency of the evaporator and the damage to equipment are also avoided; and finally, by combining a fine traditional physical model with a heat conduction process, the descaling prediction accuracyis improved.

Description

technical field [0001] The invention belongs to the field of energy technology, in particular to a prediction method and device for fouling maintenance in evaporators. Background technique [0002] The falling film evaporator is a kind of evaporator. The main working principle is that the feed liquid evaporates the liquid in the feed liquid by absorbing the heat of the fluid, so as to achieve the purpose of concentrating the feed liquid. During the concentration process of the feed liquid, according to the characteristics of the acidity and alkalinity of the feed liquid, some of them are very easy to cause fouling of the heat exchange tube. Scaling has an important impact on the normal operation of the evaporator. Due to the fouling of the evaporator, the fouling will absorb a considerable part of the heat and is not conducive to the transmission of heat, which will significantly reduce the operating efficiency of the evaporator and increase energy consumption. [0003] Th...
