Description
Technical field
The present invention relates to sterilizing and purifying device field more particularly to a kind of ozonization plant and use its disinfection side
Method.
Background technique
Disinfection includes killing microorganism, removal organic matter, and microorganism includes bacterium, virus, and organic matter includes formaldehyde, first
A variety of harmful organic substances such as benzene, dimethylbenzene.
Hospital's segment space, to surface sterilization, is still diffused the fishlike smell of one ozone for second day, allowed using ozone in space
People feels unpleasant, while there are some potential safety problemss to medical staff and patient.It is often smelly in order to mitigate second day ozone taste
The concentration of oxygen disinfection is low and the time is short, cannot reach thorough disinfection purpose.
Quilt, pillow have certain disinfection by sun Sai, there is a small amount of ultraviolet light in sunlight, are shone for a long time by sunlight

The ultraviolet radiator 3 of the reduction ozone places according to the form of chlorination equipment, arranges, it should be made sufficiently to irradiate wait disappear
The space of malicious taste removal, and keep space Values In Ultraviolet Irradiance uniform, improve ultraviolet radiation factor K2, improve ozone reduction speed.Generally
Ground, K2The ratio between radiation-curable volume/spatial volume is approximately equal to multiplied by the radiation uniformity, when the ultraviolet radiator 3 of reduction ozone can spoke
When being mapped to entire space, the ratio between radiation-curable volume and spatial volume be 1, if because equipment cavity limit, can only partial radiation,
The ratio between radiation-curable volume and spatial volume less than 1, radiation the uniformity because reduction ozone ultraviolet radiator 3 it is related with spatial position,
It can be between 0.1~1.0, to shorten ozone reduction time K2As close possible to 1.0.
In order to accelerate ozone reduction speed, shorten the recovery time, other than lamp current density, to the power of ultraviolet radiator
It needs to select.
To verify the ultraviolet reduction effect to ozone, we devise special experiment thus, test ozone respectively certainly
Right state, power are that (tube current density is 0.35A/cm to 40W ultraviolet radiator2) and power be 120W ultraviolet radiator (tube current is close
Degree is 0.45A/cm2) irradiation under the rate of decay, disinfection space volume is V=1m3, data are as shown in the table:
1 ozone of table at any time test by attenuation process
Go out ozone in nature, the irradiation of 40W ozone reduction lamp and 120W ozone reduction lamp according to upper table data preparation
Under the rate of decay and the relation curve of time be illustrated in fig. 1 shown below.
It will be seen from figure 1 that the rate of decay of ozone in its natural state is most slow, under the irradiation of 120W reduction ultraviolet lamp
The rate of decay is most fast, and the rate of decay is taken second place under the irradiation of 40W reduction ultraviolet lamp, it can be seen that: ozone is in high-power height
Under strong ultraviolet irradiation, rate of decay can be dramatically speeded up.
Control group two, V=1m3, T=32/60=0.533h, Q=23.2 × 2.14=49.65mg/m3, ultraviolet conversion effect
Rate K1=45%, the space of ultraviolet light uniform irradiation, K2=1, P=40W, recovery coefficicnt k=(P0×K1×K2×T)/(Q×V)
=0.19；Such as deduct the Natural Attenuation of ozone, Q=23.2 × 2.14 × 63%=31.28.mg/m3, then ka=0.31.
Control group three, V=1m3, T=17/60=0.283h, Q=22.6 × 2.14=48.36mg/m3, ultraviolet conversion effect
Rate K1=40%, the space of ultraviolet light uniform irradiation, K2=1, P=120W, recovery coefficicnt k=(P0×K1×K2×T)/(Q×V)
=0.28；Deduct the Natural Attenuation of ozone, Q=22.6 × 2.14 × 78.3%=37.86mg/m3, then kb=0.36.
The Natural Attenuation of ozone is larger with temperature, humidity, surrounding medium, illumination effect, and experimental comparison group is in the natural ring of light
It is carried out under border, there are the irradiation of low Values In Ultraviolet Irradiance in natural light, under dark surrounds, Natural Attenuation amount is likely to reduced, Natural Attenuation

=1, then the ultraviolet radiator power P for restoring ozone is greater than 14.3W；It is required that 0.5 hour by ozone concentration by 60mg/m3Be down to
0.1mg/m3Hereinafter, then ultraviolet radiator power is greater than 85.7W.60m3At 3 hours by ozone concentration in the space that ultraviolet light can irradiate
By 30mg/m3It is down to 0.1mg/m3Hereinafter, ultraviolet radiator power is greater than 428.6W；1 hour by ozone concentration by 30mg/m3It is down to
0.1mg/m3Hereinafter, ultraviolet radiator power is greater than 1285.7W.The value of recovery coefficicnt k is bigger, indicates that ozone reduction speed is got over
Fastly, thus the power requirement of ultraviolet radiator is bigger.
It should be noted that using low power ultraviolet radiator ultraviolet irradiation, the reduction rate of ozone compares Natural Attenuation
Much faster, the value of recovery coefficicnt k includes but is not limited to k >=0.25Wh/mg, not absolute lower limit value, can also be with value
It is smaller, such as >=0.10Wh/mg, >=0.15Wh/mg, >=0.20Wh/mg, the present invention pursue Quick ozone reducing, choose one compared with
Big value.
The minimum value of k is respectively as follows: k >=0.25Wh/mg, corresponding P >=0.25 × Q × V/ (K1×K2×T)；
K >=0.30Wh/mg, corresponding P >=0.30 × Q × V/ (K1×K2×T)；
K >=0.35Wh/mg, corresponding P >=0.35 × Q × V/ (K1×K2×T)；
K >=0.40Wh/mg, corresponding P >=0.40 × Q × V/ (K1×K2×T)；
K >=0.45Wh/mg, corresponding P >=0.45 × Q × V/ (K1×K2×T)；
K >=0.5Wh/mg, corresponding P >=0.5 × Q × V/ (K1×K2×T)；
K >=0.55Wh/mg, corresponding P >=0.55 × Q × V/ (K1×K2×T)；
K >=0.6Wh/mg, corresponding P >=0.6 × Q × V/ (K1×K2×T)；
K >=0.7Wh/mg, corresponding P >=0.7 × Q × V/ (K1×K2×T)；
K >=0.8Wh/mg, corresponding P >=0.8 × Q × V/ (K1×K2×T)。
The value of recovery coefficicnt k is bigger, and power is bigger, and circuit load is big, while chlorination equipment system cost is high, from practical
Property angle is set out:
The maximum value of k is respectively as follows: k≤2.0Wh/mg, corresponding P≤2.0 × Q × V/ (K1×K2×T)；
K≤1.8Wh/mg, corresponding P≤1.8 × Q × V/ (K1×K2×T)；
K≤1.5Wh/mg, corresponding P≤1.5 × Q × V/ (K1×K2×T)；
K≤1.2Wh/mg, corresponding P≤1.2 × Q × V/ (K1×K2×T)；
K≤1.0Wh/mg, corresponding P≤1.0 × Q × V/ (K1×K2×T)。
