The main objectives of this project are to increase the efficiency of the cleaning mechanism in a falling film evaporator and to recover the heat and chemicals contained in the cleaning agents. An evaporator cleaning system uses energy to dissolve or suspend material adhering to the evaporator tubes. This energy may be provided in the form of kinetic, thermal or chemical energy. Conventional cleaning systems have traditionally relied on the last two energy forms. However, this project greatly increases the efficiency of cleaning by increasing the flow of the liquid detergent, i.e. by using the kinetic effect. Larger pumps are used to achieve an improved flow rate and these pumps are dedicated to the cleaning process alone. Unlike conventional systems, the system described re-uses its cleaning agents. It reduces energy consumption in the form of electricity and steam usage, while also reducing chemical and water use. It also increases plant availability and reduces the waste chemical load on the environment.
