Whirlwind apparatuses

The problem of clearing of great volumes of gas emissions of the industrial factories in an aerosphere can be solved for the account of application for these purposes of apparatuses of whirlwind t)q)e. Use in whirlwind apparatuses of centrifugal separation of phases removes restriction... 

Thus, the analysis of the observed designs of whirlwind apparatuses allows to draw a conclusion about possibility of working out of highly effective irrigated whirlwind apparatuses for clearing and cooling of gas streams. 

Without research of three-dimensional stmcture of sharp twirled stream, it is impossible to size up correctly new design solutions and to find boundary lines of conversion zones of woik for whirlwind apparatuses, it is impossible to define, whether peak efficiency of target process, and the main thing is attained,—it is impossible to create the similarity theory of sharp twirled streams necessary for realized and purposeful perfection of gas-cleaning installations.

At direct-flow interacting of streams, the liquid from a contact zone is taken out with a great speed. Tests have shown that the most effective branch of a liquid from gas (steam) is attained in the field of a centrifugal force. Presence whirlwind, is forward-rotary motion in a RC is another feature of whirlwind apparatuses[ll-16]. 

The high speed of the easy phase, which are carrying away in direct-flow motion a liquid, and reliable separation of phases after interacting in a vortex flow allow to intensify sharply a mass transfer and in 3-8 times to increase carrying capacity of the apparatus. Application of whirlwind apparatuses for a dust separation (Ershov, 1973 Prihodko, 1979 and Diarov, 1979) is presented. 

Basic element of whirlwind apparatuses is whirlwind contact devices (W CD). They consist of a contact coimecting pipe, an air swirler, knots of input of a liquid in a contact, and separation zone[25-26]. 

Comparison of possibilities a gas-cleaning installation of various types also testifies to preference of application of whirlwind apparatuses at clearing of great volumes of gas emissions. 

Formation of streams in whirlwind apparatuses, their parameters of work (efficiency of conducting warmly—and mass-transfer processes, a water resistance, etc.) are defined by a build and sizes of whirlwind apparatuses and regimes of their work. 

In any whirlwind apparatuses of a pressure loss are one of the major characteristics. They are necessary for knowing for sampling of fan devices, an estimation of efficiency of expenses of energy, comparison of various ways of conducting warmly- and mass-transfer processes, designing of apparatuses, their elements and systems. 

Pressure losses in whirlwind apparatuses develop of following components ... 

Most full the theory of a water resistance of whirlwind apparatuses is devised in Ref Anthony (1970) and Uzhov (1973). 

The analysis of known builds of rotary connections has allowed to reveal major factors (loading on a liquid phase, a monkey wall and a stream breakaway, discharge cormection sizes), working upon a water resistance of whirlwind apparatuses. Resistance is defined by the sum of pressure losses of an air swirler, in the separation chamber and on an exit from it. It is shown that pressure losses in an air swirler depend on its geometry and extent of a twisting of gas.

The aerodispersion ftalo-air gas-vapour mixture was cleared of a dispersoid, at change of gas rates 196-250nm /h and a dispersoid 0.62-23.0nm As a result of experiences have been installed that efficiency of separation in the whirlwind apparatus with the right-angled twisting channels makes 96 percent. Thus the air swirler water resistance was in limits of 50mm.water.coliunn.
