NTRODUCTION
Dust and toxic gases from technological processes
are increasing the pollution of the environment.
Therefore, the only way is to protect the
environment and find solutions to industrial
problems. There are several types of dust and
toxic gases emitted from manufacturing plants,

and the unfortunate one is the presence of toxic
substances among them that have toxic
properties. At present, production facilities use
devices of various structures to clean dust and
toxic gases. One of the most effective ways to treat
dust and toxic gases is wet cleaning, which uses
several designs of this type of equipment. Various
contact elements are used to humidify the dusty
gases in the devices used. However, the
consumption of the device, hydrodynamic
resistance, and low efficiency of dust removal
from the formed sludge do not allow optimal use
of the device. The efficiency of this type of device
is only 76 ÷ 90%.[1,2]. In order to solve these
problems, we conducted experimental studies to
determine the coefficient of resistance in the
apparatus through the flow of liquids and gases in
the apparatus, which designed and developed the
contact element fluctuating current [3,4]. The
contact element is in a current-generating
apparatusthe following required equipment and
apparatus were selected as the experimental
model in determining gas velocity, flow, flow
regime, and local resistance coefficients.

branded digital screen electronic meter; metal
pipe with gas flow rate D = 100 mm, L = 1000 mm.
One of the main parameters that determine the
stable operation of dust gas cleaning is its
hydraulic resistance.
Therefore, in determining
the velocity of the gas, a suction tube with an
angle of 00, 30o, 45o, 60o, 90o was installed in the
suction pipe of the fan. The main reason for this is
to determine the coefficients of hydraulic
resistance of the apparatus at different velocities
of the gas, and thus to conduct experimental
studies.
Each experiment was performed 5 times and the
arithmetic mean value of the detected quantities
was selected. (The kinematic viscosity of the air
