BSTRACT
Cleaning of harmful dust and gases generated in technological processes today is one of the important tasks
of this day. Therefore, the main working factors affecting the cleaning process were determined in the
experimental model of the newly developed contact element accumulative flow generator. The gas velocity,
gas and liquid consumption in the apparatus, the length of the liquid film and the working surface were
determined based on experiments.

Leaf contact elements of different slopes were
selected for the apparatus, which creates a
lumped current. Based on the conducted
theoretical and experimental studies, preliminary
requirements for the device and technical tasks
were developed.
The following necessary equipment and devices
were selected for the experimental model to
determine the length of the liquid film through
the gas velocity, liquid and gas consumption, flow
regime and hydraulic resistance coefficients in
the wet dust collector and gas cleaning apparatus
(Fig. 1) [1-7].

selected. The length of the liquid film depending
on the diameters of the nozzle holes and gas
velocities was determined for the variation of
liquid and gas consumption. Experiments were
conducted in the following order [8-11].

D=100 mm, L=1200 mm. 2 Prandtl tubes with an
inner diameter of 7 mm, which determine the
static and dynamic forces in the pipe, were
selected as the experimental model, respectively.
Figure 2. 30 degrees; Overview of 45o and 60o contact elements.
Gas velocities and contact elements(zavikhritel)
depending on the change of slope angles and the
length of the liquid film were determined through
resistance coefficients. Figure 1, 2 30 degrees;
45o and 60o contact elements are provided.
Experiments were conducted in the following
order [2,3].
Gas velocities depending on changes in liquid and
gas consumption supplied to the device, angle of
inclination of contact element pieces(zavikhritel)
a=30o; 45o and 60o and the diameter of the
nozzle hole dsh=2; Experiments were conducted
to determine the length of the liquid film formed
in the working chamber when 2. 5 and 3 mm.
Liquid consumption according to the results of
the experiment when the rotometer scale shows
0÷100 and the length of the liquid film formed in
the working chamber of the apparatus when the
gas velocity is up to yg=7. 07÷28. 37 m/s is 30÷It
was found to be 335 mm. In experimental studies,
liquid film growth averaged 12÷showed an
increase in the range of 16 mm.
C
ONCLUSION
From the experiments carried out to study the
effect of the length and thickness of the liquid film
on its cleaning efficiency through liquid and gas
consumption, gas velocity and hydraulic
resistance, it can be concluded that the increase in
the angle of inclination of the contact element
blades that move the gas flow in the apparatus
ensured the thickening of the liquid film layer. But
it led to a decrease in the working surface. On the
contrary, the decrease in the angle of inclination
of the contact element blades led to an increase in
the length of the liquid film and an increase in the
working surface. With this, by increasing the
length of the liquid film in the working chamber
of the device and increasing the working surface,
