Description
Background technique
Ozone is light blue gas, is a kind of extremely strong oxidant, by oxidation, inhibits the breeding and life of bacterium
It is long, and lead to the death of bacterium, it is a kind of strong fungicide again.Ozone can be dissolved in water, and the Ozone Water of certain ozone concentration is same
With extremely strong bactericidal effect.Ozone and ozone water energy are sterilized and are sterilized to food, drinking water, are disappeared to drinking water
When malicious, in addition to the bacterium in water can be killed, it is further purified outside the impurity in water, moreover it is possible to increase the oxygen content in water.Ozone and
All kinds of skin diseases that Ozone Water causes bacterium, bacterial inflammation, the diseases such as burn surfaces have certain curative effect.Ozone and
Ozone Water also has many advantages, such as without side-effects, non-toxic, without secondary pollution.Therefore, it is widely used in drinking water, food
The fields such as processing, health care, chemical industry, environmental protection.
The method for preparing ozone has corona method and electrolysis method, and electrolysis method is again can prepare high-concentrated ozone better than corona method.
Current electrolytic ozone generator, by electrolysis ozone generator, electrolysis ozone generator power supply, anode water tank, cathode water tank
Composition.The ozone amount that single ozone generator can be prepared within the unit time is limited, can not meet actual use well
It needs, in the prior art, generally carries out that centralized system is standby and centralized collection by the way of the joint setting of multiple ozone generators,
Ozone amount to be electrolysed is just concentrated use in after reaching a certain level, such as: CN1900367, CN2430450Y,
CN2515207Y, CN2518840Y, CN2835228Y etc., these are all made of two to three electrolysis ozone devices processed in the prior art
It is used in combination, the rate of electrolytic preparation ozone can be improved to a certain extent, there is certain using effect and industry
Meaning.But using several electrolysis installations prepare ozone amount be still it is extremely limited, large area can not be met well
The demand of the large area disinfections such as the demand of disinfection, such as food workshop, greenhouse sterilizing.And it is smelly in order to be applied in large area sterilizes
Oxygen, it is necessary to using a large amount of ozone gas perhaps ozone liquid this just to the preparation facilities band of Ozone Water or ozone gas
Huge pressure is carried out, in order to adapt to this demand, large number of ozone generator is formed into array by technical staff, has carried out
Large-scale ozone preparation and collection.This technology make it possible in wide area carry out ozonization, but with
And come problem be: how these large number of ozone generators are reasonably controlled.If only individually control
Make the switch start and stop of these generators, it is clear that be not able to satisfy the needs of reasonable employment, energy-saving and emission-reduction, and in larger area range
It is interior in use, being not that whole ozone generators requires to be switched on, therefore, it is necessary to smelly in entire ozone generator array
Oxygen Generator carries out planning as a whole control and reasonable arrangement, and ozone amount needed for can either meeting disinfection also can properly control ozone
The available machine time of generator, the technical effect for playing and reducing energy consumption, avoid ozone generator excessive loss.But at present not
There is similar control method, therefore, in order to reach expected technical effect, needs to develop corresponding array ozone generator control
Method processed.
Summary of the invention
The present invention is mainly to solve not being suitable for the skill to multi-quantity, array ozone generator present in the prior art
Art problem provides a kind of real work for sterilizing actual demand based on wide area while considering array ozone generator
Situation and the situation of change of sterile environment, an appropriate number of ozone generator can be distributed with reach suitable ozone production capacity and and
When meet disinfection demand array ozone generator control method.
What the present invention was mainly addressed by following technical proposals in view of the above technical problems:
A kind of control method of array ozonization plant, the array ozonization plant include that multiple ozone occur
Device, several ozone generators form an ozone generator group, and there are multiple ozone generator groups, multiple ozone generators
Group is connect by several depot sidings with ozone tank respectively, and the Ozone Water that electrolysis generates is transported in ozone tank by pipeline；
If several ozone generators and corresponding ozone generator group are connected into array configuration by trunk pipeline；Several ozone occur
Device group rotation discontinuous operation makes to maintain a certain amount of Ozone Water storage in ozone tank, and maintains necessary ozone concentration.
The control method the following steps are included:
(1) ozone demand of environment to be sterilized, the current state of environment to be sterilized are obtained, Ozone Water deposits in ozone tank
The current working status of amount and each ozone generator group；
