Scrubber dust clearing efficiency

On the basis of the observed inertia of model the method of calculation of a dust clearing efficiency in scrubbers with inner circulation of a fluid is developed. 

Determining relation of efficiency of trapping of corpuscles of a dust in a rotoklon from performance of a trapped dust and operating conditions major of which is speed of a gas flow in blade impellers. To develop a method of calculation of a dust clearing effieieney in scrubbers with inner cireulation of a fluid. 

Before an entry in the contact partition of the apparatus there is a contraction of a gas flow for gas speed enhancement, acquisition of high layers of a fluid and its entrainment in the contact channel. Functionability of all dust trap depends on efficiency of acquisition of a fluid by a gas flow—without fluid acquisition will not be supplied effective interaction of phases in the contact channel and, hence, qualitative clearing of gas of a dust will not be attained. Thus, fluid acquisition by a gas flow on an entry in the contact device is one of the defined stages of hydrodynamic process in a scrubber with iimer circulation of a fluid. Fluid acquisition by a gas flow can explain the presence of interphase turbulence which is advanced on an interface of gas and liquid phases. Conditions for origination of interphase turbulence are the presence of a gradient of speeds of... 

Defining characteristics of apparatuses for clearing of gas emissions are efficiency of separation and water resistance. Known methods of calculation of efficiency of the scrubbers based on the use of empirical functions, presenting parameters of fractional efficiency and dispersion composition of a dust, do not vary the significant accuracy. It is caused by the functions of mass particle size distribution of many industrial dusts which do not answer a logarithmically normal [lognormal] distribution because of the actions of several mechanisms of a dust formation. Use of some methods are inconvenient because of multistep, complexities, and labor contents of reception of initial data for calculation.
