The valves of a
"Glitch" type are already more than 50 years and they for a long time
require replacement by more efficient ones. Our devices offer to do it without
radical change of technology and equipment for manufacture of columns with valve
contact elements. More 50 inventions are developed.
There are the next groups of devices
1. Contact devices for opposite gas-liquid current with own zone of
liquid flow in every device and with two zones of contact of phases (bubble and
film) in every element. There are about 10 variants and versions. In comparison
with traditional Glitch valves they provide higher gas velocity (F-factor up to
2.5), plate liquid density till 180 m3/m2hour at high
efficiency of mass-transfer (at a
level "Glitch" and above on 10-15
%).
These devices are intended for realization for processes of absorption at
high "liquid - gas" ratio, for example, at bromine absorption by
water, gas cleaning, etc.
2.
Liquids inject valve contact devices with re-circulation of a gas-liquid mix
through contact device and co-knocking of flows. In difference of usual bubble
device generated beforehand biphase flow is going in a liquid. Provide the large
time of contact of a liquid with gas, high efficiency of contact of phases, high
flexibility (as at increase of loading on gas is increased a time of circulation
of a liquid through contact unit). Are intended for absorption equipment with
parallel proceeding chemical reaction and gas-liquid chemical reactors.
3.
Oscillating and pulsing valve contact devices ensuring imposing of fluctuations
on contacting phases of optimum frequency. It results in improvement of the
hydrodynamic characteristics and efficiency of phase contact.
4. One
direction gas-liquid devices with repeated (multiply) inversion of phases. These
devices do not excel in the world on flexibility, efficiency and throughput. The
realizations of chemical reactions are intended first of all for clearing gases.
5.
Polymeric (Teflon) valve contact apparatuses for reception of high cleaning
substances (micro-radio-electronics, fiber optics, etc.).
