CONTACT DEVICE FOR HEAT, MASS-EXCHANGE AND SEPARATION PROCESSES, CONTACT BRANCH PIPE FOR IT, SWIRLER AND LIQUID SUPPLY DEVICE FOR BRANCH PIPE Russian patent published in 2018 - IPC B01D3/30 B01D45/14 

FIELD: manufacturing technology; technological processes.

SUBSTANCE: invention relates to the heat, mass-exchange and separation processes contact devices and can be used in gas cleaning of fine-dispersed mechanical impurities and a dropwise liquid, in the absorption, desorption and rectification processes. Technical result is realized by the construction of a multiblade swirler with its using in the contact device contact branch pipe, each of the blades is in the form of an elongated plate and are fan-shaped at an acute angle to its axis with partial overlapping on adjacent plates. Outer lateral edges of the blades form a conical surface of the swirler, oriented with a large base upwards, the height of the swirler cone is 1.2–1.4 times greater than the inner diameter of the contact branch pipe. Each blade inner edges are unfolded or bent inside the swirler relative to their outer edges with the formation of slit-type gaps between adjacent blades. Total cross section of the slit-type gaps between the blades is 0.9–1.1 of the contact branch pipe internal cross-section. Means for supplying liquid to the lower part of the swirler is made in the form of the horizontally arranged pass-through tube section with inlet openings at the ends, and in the upper side part the middle part of the pass-through tube is provided with a channel for connection to the inlet of the swirler.

EFFECT: by reducing the hydraulic resistance over the gas and liquid flows, uniform distribution of the atomized liquid in the swirler volume in the dispersion zone, increase in the contact surface of media an increase in the mass-exchange device performance and the gas washing intensity is enabled.
