Experimental studies of a wet single-zone electrofilter

Relevance . In the context of increasing requirements for air purity at industrial enterprises, electrostatic precipitators are of particular importance as an effective means of removing harmful particles from the air. The issues of their optimization remain relevant, since the level of purification and the cost-effectiveness of production processes depend on it. The purpose . To conduct an experimental study of a wet single-zone electrostatic precipitator and determine the influence of design and operating parameters on its efficiency. Methods . The electrostatic precipitator under study differs from classic electrostatic precipitators in the design of the precipitating electrodes. The precipitating electrodes are made in the form of round, rotating disks, which are half immersed in liquid for continuous cleaning. For the study, an experimental stand with a wet single-zone electrostatic precipitator was used, in which the key parameters were changed: supply voltage, distance between electrodes, radius of the precipitating electrodes and air flow velocity. The efficiency of the filter was estimated by measuring the concentration of particles before and after air purification. Each experiment was carried out for 20 minutes and repeated 5 times. Results . Based on the test results, graphs were constructed of the dependence of the air purification efficiency of the electrostatic precipitator on the design and operating parameters. The experiments showed that the air purification efficiency decreases with an increase in the air flow rate and interelectrode distance, while an increase in the voltage and diameter of the electrodes improves the cleaning quality. Graphic dependences of the efficiency on the variable parameters were obtained, which made it possible to identify the optimal parameters. Conclusion . Optimization of the parameters of the wet single-zone electrostatic precipitator helps to increase the air purification efficiency, which allows to reduce harmful emissions at production sites and improve the environmental friendliness and cost-effectiveness of production processes.
