Application and design requirements.

Scrubber components:

- multi-section scrubber frame;
- irrigation system with centered tangential jets (replaceable);
- with sludge regulative float device;
- emergency water supply system

Contaminated gas is fed by inclined gas flue to the bottom of the scrubber and rises up the frame. On the top of the scrubber there are 3 irrigation tiers, which consist of centrifugal jets. Lime-water suspension  (CaCO3), that is under pressure, is spraying. Drops of aqueous solution CaCO3, are falling due to gravity towards contaminated gas.  Water drops capture dust articles happens due to inertial and diffusion mechanism, hydrodynamic and electrostatic forces and turbulent diffusion.  Gas cleaning from sulfur oxides is based on absorption technology. After contact of lime-water suspension with gas, reaction takes place:

control system and automatics for the scrubber

Control system and automatics for the scrubber

СаСО3 + SО2 + ½ Н2О = СаSО3·1/2Н2О + СО2
Oxygen, which is in the products of combustion, oxidizes the calcium sulfate in neutral sulphate (gypsum):
СаSO3 ·1/2H2O +1/2O2 = CaSO4·2H2O

Exhaust aqueous solution with gypsum and captured dust is accumulated in the bottom of the scrubber.  Peeled gas is fed by gas flues, which are located on the top of the device. For pulling of the sludge there is a special device, which consists of float camera and throttle control, that supports a given level of sludge in the hopper.

Scrubber frame is designed for organization of gas flows and water drops. Irrigation system is designed for supplying and spraying of the water in the scrubber frame. Drainage sludge mechanism is designed for automatic removal of sludge from scrubber frame. Emergency water supply system is designed for stopping of water supplying if it is impossible  to remove sludge from scrubber frame.

MXene is one of the most sensitive gas sensors ever reported

MXene gas sensorsMXene is one of the most sensitive gas sensors ever reported that sniff out chemicals in the air to warn us about everything from fires to carbon monoxide to drunk drivers to explosive devices hidden in luggage have improved so much that they can even detect diseases on a person’s breath. Researchers from Drexel University and the Korea Advanced Institute of Science and Technology have made a discovery that could make our best “chemical noses” even more sensitive.
