Research of the Equipment of the Washing Liquid Purification Unit With Analysis of the Energy Efficiency of Foam Generators in Conditions of Variable Pressure and Liquid Flow

The article considers the issue of increasing the energy efficiency of the equipment of the washing liquid purification unit with an emphasis on the analysis of the operation of foam generators under conditions of variable pressure and liquid flow. Given the growing requirements for energy conservation, emission reduction and efficient use of resources in industry, it is relevant to determine the optimal parameters of the functioning of foam generators, which allow ensuring stable foam formation with minimal energy costs. The study used the method of numerical modeling of processes in the FlowSimulation software environment (SolidWorks), which made it possible to build a mathematical model of the foam generator operation and calculate energy efficiency coefficients at different operating modes. The analysis of the influence of changes in liquid flow (from 0.001 to 0.025 m³/s) and pressure (from 6 to 12 MPa) on the efficiency of the device's operation was carried out. It was established that the most optimal mode is a liquid flow of 0.015 m³/s and a pressure of 8 MPa, at which the highest ratio of productivity to energy consumption is achieved. Outside this range, the efficiency decreases: when the flow rate decreases to 0.001 m³/s, the energy efficiency coefficient is 1–1.09, and when it increases to 0.025 m³/s, it is 1.14–1.45. The results obtained have applied value for optimizing technological processes of liquid purification and modernization of industrial plants, contributing to reducing energy costs, increasing production efficiency and improving environmental performance. The article can serve as a scientific and practical basis for further research in the field of energy saving, automation of purification systems and environmental safety of technological equipment. The proposed approach can also be adapted to other types of equipment, where efficiency depends on the dynamics of hydraulic parameters, which opens up prospects for the development of complex energy-saving technologies in various industries.
