The electric method of gas dedusting is the most
effective, since it allows capturing solid particles with
a size from 0.01 µm to tens of microns. The efficiency
of dust and gas cleaning equipment of Novocherkassk
SDPP for cleaning flue gases from ash at power units
1-7 in the period from February 2015 to February 2017
is considered. The main equipment is electrostatic
precipitators. As a solid fuel, Donetsk culm is used. It
is established that the efficiency of waste gas
purification at power units 5-7 was about 99 %, while
at power units from the 1st to the 4th this value was
within 95-96 %. The data obtained correspond to the
design data, but it is recommended that the cleaning
devices be improved to improve their efficiency. The
most acceptable is a combined electrofilter-bag filter
After silage of ash captured by the electrostatic
precipitator, we installed the cyclone of NIIOGAZ
CN-15-500 for exhaust gas pre-treatment of the ash
resulting from the process of burning solid fuels (coal
of Donetsk) in boilers of Novocherkassk hydro power
plant. The plant cyclone examination was performed in
a production environment of Novocherkassk hydro
power station comprising 4 cylindrical cyclone
element diameters of 500 mm, and is defined by its
real effectiveness, which amounted to 91%. After the
cyclone, the gas enters the two-bag filter FRKI-90KP3-2-2
designed to trap solid ash residues and installed
over the silo dry ash. Filters are manufactured in
climatic design for temperate and cold climate with the
accommodation category 4. The article shows the
characteristic of the test results and bag filters FRKI-
90K-P3-2-2 before and after the cyclone in the
cleaning system. The work presents the analysis of the
composition of the ash and compares it with published
data. It is experimentally proved that the inclusion of
Cyclone CN-15-500 in the process diverting gas
purification scheme allowed more efficient operation
of fabric filters, reducing the dust significantly for the
input gases
Groundwater is the source of drinking water in rural areas, it is a part of urban water and it is formed due to the filtering of cross waters in a stratified medium permeable rocks. The impact of anthropogenic factors leads to changes in the qualitative composition of groundwater. The article presents the results of industrial environmental monitoring of ground water refinery of Tuapse in the period from 2012 to 2016 according to its content of ammonium-nitrogen, nitrate-ions, sulphates, formaldehyde, toluene, xylene and ethylbenzene. Analysis of groundwater sampled from wells located at the site of the refinery was conducted by a factory-certified laboratory. The content of the components meet the regulatory indicators. We examine the effects of industrial toxicants on the human body
The article presents results of research on drying a
slurry consisting of distilled water and finely chopped
cooked chicken protein of table eggs. The suspension
is placed in a Memmert oven, which has temperature
of 60 °C. In the process of removing moisture when
drying the slurry of water - boiled protein we
examined kinetics of its drying and performed
chronological photographing of conformation of the
system of water - boiled protein. The final weight of
the protein remaining after evaporation, was 0.06 g
corresponding to 26% by weight of cooked protein
source in an amount of 0.23 g. The analysis of the
system appearance including the evaporation of the
water showed that the protein was originally white,
and this color does not undergo any changes until 35
minutes of drying, i.e. when the main base is water.
Upon further drying of the suspension, starting with 40
minutes, boiled protein literally "melts" in the
surrounding water residues; and as it is disappearing,
becoming more and more transparent. Meanwhile, the
forms of the protein are becoming round and
transforming into the form of liquid crystals. The final
phase of the protein is a solid transparent film
