The work is devoted to studying the hydrodynamics of highly efficient equipment for the complex treatment of dust and gas emissions. One way to reduce dust and gas emissions is to increase the efficiency of gas cleaning equipment. The considered designs of the devices for clearing exhaust gases work in the mode of the developed turbulence. Devices with a regular pulsating nozzle are characterized by high efficiency in catching solid particles of different dispersion, self-clean the contact elements from dust, low material consumption, and high reliability in operation. The study's primary purpose is the physical description of structures and the analysis of hydrodynamic modes of operation devices for the integrated treatment of dust and gas emissions in industrial enterprises. This goal is achieved by describing the structures and the physical picture of the interaction of gas and liquid phases in the volume of the studied devices, the establishment of the main hydrodynamic modes of operation, and optimal operating ranges of equipment at gas speed. The regular arrangement of the nozzle elements on the string allows you to organize vortex zones with a specific set step in both longitudinal and transverse crosssections, ensuring uniform flow distribution and homogeneity of the gas-liquid layer. In the ejection and nozzle versions of devices with a regular pulsation nozzle, we can clearly distinguish three hydrodynamic modes: countercurrent, transient and direct current. The operating mode is direct current. Studies of devices with a regular pulsation nozzle suggest its use for the comprehensive treatment of dust and gas emissions of enterprises to reduce the negative impact on the environment
