Ozone gas-water hybrid technology and
product introduction
Introduction of ozone gas and water mixing device
High ozone oxidation treatment effect of the main factors in
addition to the nature of pollutants, concentration, ozone dosage,
pH, temperature, reaction time, the gaseous O3 dosing method is also
very important. O3 dosing is usually mixed reactor. Mixing reactor
(contact reactor) role has two; ① promote gas, water diffusion
mixing; ② so that gas, water full contact, rapid response; ③
increase ozone gas in water residence time; mixing reactor design to
consider when ozone the water molecules in the diffusion rate and
the reaction rate and pollutant. When the diffusion rate is large,
and the reaction rate of the ozone step speed control process, the
mixed structure of the contactor should be sufficient to facilitate
the reaction. Pollutants in this category alkyl sulfonate, tar,
CODcr, BOD5, sludge, ammonia, etc., the reactor can be microporous
diffuser plate bubble column. When the reaction rate is large, the
diffusion rate for the entire ozonation process speed control steps,
structure type should be conducive to ozone accelerated
proliferation. Fall into this category of pollutants of iron (II),
Mn (II), cyanide, phenol, hydrophilic dyes, bacteria, etc.,
generally water treatment can be used as a reactor injector, the
effect is more ideal.
Microporous diffuser plate bubble column shown in Figure 1-5.
Ozone gas from the bottom of the microporous diffuser plate
(diameter of about 15 ~ 20um) ejected countercurrent contact with
the waste; tower can be filled with ceramic ring, plastic ring
packing, in order to improve water vapor exposure conditions. The
device is characterized by a long time can maintain a certain
concentration of ozone is conducive to ozone and water pollutants
adequate response. In addition, the device has a large liquid
volume, volume adjustment easy.
Partial flow jet contactor shown in Figure 1-6. High-pressure water
through the ejector and the ozone gas inhaled water, this device is
characterized by a well mixed, but the contact time is shorter.
Recently, there was a static mixer (Figure 1-7). Also called static
mixer tube mixer, a pipe installed in a number of propeller blades,
propeller blade has the adjacent two opposite directions, the flow
dividing the rotary motion generated by contact with the ozone many
tiny vortices. The water gas are fully mixed. The ability to mass
mixer, ozone utilization of up to 87% (73% pore diffusion), and less
energy-consuming equipment, low cost, high performance I produced
mixed results while incorporating aeration Hybrid integrated mixing
and jet apparatus has added a static mixing device (see product
navigation - gas-water mixing device) greatly enhance the
disinfection of drinking water in the gas-water mixing efficiency.
Since ozone gas is generated by high-energy method, ozone exposure
is also very important economic benefits. Contact system appropriate
cost - benefit assessment should seriously consider are:
(1) The actual amount of dissolved ozone;
(2) contact the solute and (or) the efficiency of the reaction
suspension;
(3) contact or diffusion means of the energy needed for the
operation;
(4) different contacts each specific maintenance tasks:
(5) Operation processing charges.
For a higher degree of mixing
or shear sufficient to produce the interface area, can use the
mixing tank, a static mixing apparatus, and an axial mixer (pipe
mixer) associated with.
Representative equipment:
BNP-YWS type high concentration ozone water disinfection equipment
Using a gas filter, high
concentration of oxygen gas source, ozone generator, static mixing
device and a dynamic mixing and integration integration technology.
BNP-YWS type high
concentration ozone water disinfection equipment Main technical
characteristics:
● Ozone concentrations up to
1mg / L, 2mg / L, 3mg / L, 4mg / L-10ppm, can replace chemical
fungicides and UV sterilization.
● The PSA oxygen gas source,
so high concentrations of ozone, avoiding the use of air source of
nitrogen oxides into the drinking water treatment applications
generated when the nitride may affect water taste, using oxygen gas
source comparison equipment water taste sweet.
● generation of corona
discharge cell gap, high efficiency, small size, high-frequency
characteristics of a good, stable, high concentrations of ozone
produced. Ozone absorption apparatus specially designed for
real-time residual ozone gas decomposition, solve the workspace
ozone pollution problems.
● source of oxygen - ozone -
Treatment synthetic design, air and water mixed with imported
advanced gas-liquid mixing pump Southern (vortex impeller mixer),
good mixing effect. The machine then water electrical connection can
be used, without external devices, easy to operate.
● Low noise, mobility, the use
of convenient operation, good working environment. Control panel
friendly design, simple operation, and convenient.
Note: This equipment is generally applicable to high concentration
ozone water disinfection 1-2T / h of water, a higher amount of water
used for mixing tower form my company to help customers configure
different options of high concentration ozone water full set of
equipment.
