INSTALLATION OF HYDRODYNAMIC WATER TREATMENT Russian patent published in 2017 - IPC C02F1/34 

FIELD: ecology.

SUBSTANCE: hydrodynamic water treatment installation comprises a pump, a cavitation device, a system of working gas input from an external source into a stream of processed water, inlet and outlet pipelines, measuring and tuning elements. The cavitation device consists of a direct-flow convergent channel and a cylindrical chamber installed consecutively, while the convergent channel has a taper angle β=(20±5°), a length L=0.08-0.45 m, a diameter of the outlet section d=0.03-0.21 m and is designed to increase water flow rate to W≥25 m/s. The cylindrical chamber has a passage section diameter d=0.03-0.21 m and a length L=5±0.5 m, it is connected through a portioning device with a source of compressed oxygen-containing gas - an oxygen cylinder with pressure up to 150 atm, and is designed to enhance the cleaning effect of the hydrodynamic processes via conversion of liquid-phase in two-phases microbubble flow by supplying oxygen-containing gas into it with the following flow key parameters: Reynolds criterion≥ Re105; flow speed W=25-50 m/s; oxygen concentration in the flow CO₂=2.7-3.0 g/l in a gas input section; cubic liquid gas content δ=0.11-0.4; gas-vapor bubbles radius R≤100 mym; liquid and gas-vapor phases contact τtimeline τ=0.1-0.2 s; Veber criterion We=10⁵-10⁷.

EFFECT: expansion of the tool sets in the nonautonomus process to detect indicators The invention protects environment against contamination with toxic chemicals.
