After the gas is penetrated, phenomenon of voltage decreases between the poles and
the dark glow around the electrode.
3.9 Epilogue gas
An ozone-containing gas that is produced in an ozone water generator but not
completely dissolved in water.
3.10 Dew point
The temperature at which the gas source starts to become dew; the lower the relative
humidity of the gas, the lower the dew point temperature.
3.11 Specific consumption
The electric energy that is consumed by the ozone generator to produce a unit weight
of ozone.
4 Specifications and classifications
4.1 Specifications
The specifications of the ozone generator are represented by the amount of ozone
produced in a unit time (the basic unit is g/h).
4.2 Classification
4.2.1 Type
4.2.1.1 Work type is divided into ozone generator or ozone-water generator.
4.2.1.2 Placement is divided into table, standing, mobile and separate type.
4.2.2 Model marking
4.2.2.1 The structure of the ozone generation unit is divided into tube type (G) and
plate type (B).
4.2.2.2 The control methods of the ozone generator are divided into common type
(fixed type, P) and adjustable type [manual-adjusted (R), and program-adjusted (C)].
4.2.2.3 The working frequency of the power supply is divided into power frequency,
medium frequency and high frequency.
b) The frequency of the power supply is 50Hz±1Hz, the voltage is 220V±22V, the
atmospheric pressure is 86kPa~106kPa, and the relative humidity is
65%~85%, the temperature is room temperature;
c) The exit gas temperature should be < 27°C;
d) The output ozone concentration of closed type ozone generator should be ≥
12mg/L.
When the above conditions are changed, the corresponding indicator such as
discharge (corona discharge or glow discharge) per unit area of ozone yield,
concentration, output and electricity consumption should be measured according to
the specific conditions.
6.2.2 All kinds of electrical insulation parts of the ozone generator should meet the
requirements of high voltage insulation performance and structure. The insulation parts
in the environment of the glow discharge, ozone oxidation should also meet the
requirements of GB 9706.1.
6.2.3 For those using water as coolant, the consumption of cooling water per kilogram
of ozone should not exceed 1.5×103 kg.
6.2.4 The average life-span should be ≥ 20 000 h;accumulative working time without
fault should be ≥ 8 000 h.
6.3 Conditions for using ozone generator
Under the condition of ambient temperature below 45°C, atmospheric pressure
86kPa~106kPa, relative humidity 65%~85%, and the cooling water temperature lower
than 35°C, the ozone generator should be able to be used continuously.
6.4 Requirements for disinfection
6.4.1 Disinfection of air
6.4.1.1 Air disinfection should be carried out in a closed space with no human inside.
The ozone concentration should be ≥ 20mg/m3, the action time should be ≥ 30min.
6.4.1.2 The effect of disinfection should comply with the related requirements of the
“Disinfection technical specification” (2002 Edition).
6.4.2 Disinfection of water
6.4.2.1 It can be used to disinfect medical institutions’ diagnosis-water (non-injection
water), dirt-water, and the water in public places.
6.4.2.2 When it is used to disinfect the medical institutions’ diagnosis-water (non-
9.4.1 For ozone generation unit’s performance spot inspection, the sampling ratio is
5%. For example, sampling unit is ozone generating unit in a single ozone generator,
and the total number of ozone generation units is < 60, then, the sampling number
should be ≥ 3 ozone generating units. The ozone generating unit’s performance test
conditions should be in accordance with 6.2.1.
9.4.2 If the data measured by performance test is 10%~20% lower than the
performance requirements and the proportion is ≥ 20% of the units checked. Then, re-
test can be carried out after finding the causes. If the performance requirements are
still not met after re-test, then, increase the sampling proportion of the ozone
generating unit to 25%. If there is no failing of the performance requirements, then spot
test can be stopped. After expansion of the sampling proportion, if the proportion of
failing ozone generating units exceeds 5% of the checked-number, then, the causes
should be thoroughly found; and the production can only be resumed after problems
are solved.
9.4.3 For new-type products or formal-products that are being manufacturing, when
there are major changes in structure, material or process, or when continuous
production life of one product exceeds 3 years, then, a number of ozone generation
units should be randomly selected to test its performance parameters and service life.
9.5 Exit-factory inspection
9.5.1 Ozone generation unit should be accurately located in the ozone generator.
Components for fastening, support and connection should be firmly installed.
9.5.2 Appearance inspection of ozone generator
Internal appearance inspection includes. parts of ozone generating unit should be
clean, no oil stains, water stains, dust or other foreign objects; the anti-corrosion
coating inside of the ozone generator should be smooth and clean with no peeling,
chipping or other adverse conditions; The high-voltage power transmission and
distribution system should be tidy and should not cause abnormal transmission and
distribution.
External appearance inspection should include. the external shell surface should be
smooth with no scar, bump, dent, or other defects affecting the appearance;
protections and other adverse conditions (if on-site external decoration will be done
according to the requirements of the buyer, this test can be carried out when
appropriate). All kinds of appurtenances (parts) on the external shell should be installed
at the accurate location, firmly fastened, and quality acceptable. Any part of the shell
shall not obstruct installation, maintenance, cleaning etc. For ozone generators with
high pressure device, the shell should be flame-retardant.
9.5.3 The interface of the ozone generator with each instrument (meter), or with
10.2.2 The package shall be suitable for water/land transportation and meet loading
requirements.
10.2.3 The text and signs outside the package include the following.
a) Company name or trademark, registered address, production address, zip code,
contact number;
b) Product name, model, specification;
c) Product net weight, gross weight, center of gravity, lifting mark;
d) Date of production, exit-factory number;
e) Power connection condition, input power;
f) Storage and transportation marks, such as "fragile items", "Rain fear", "limit of
stacking layer", etc., shall conform to the GB/T 191 regulations.
