As shown in Figure 1, the utility model provides a kind of preferable implementation for the ozone oxidation system for realizing ozone cascade utilization
Example, including ozone generator aeration head, ozone contact tank and jet aerator, the ozone contact tank includes water inlet pipe 1, first
Air-water contact area 2, the first reaction zone 4, the second air-water contact area 5, second reaction zone 7, the reaction of the 3rd air-water contact area the 8, the 3rd
Area 10, breather valve 13, vent ozone destructor 14 and outlet pipe 11, the water inlet pipe 1 and outlet pipe 11 are located at the upper of contact chamber both ends
Portion, the breather valve 13 are located at the top of contact chamber, and the aeration head includes the first aeration head 3, the second aeration head 6 and the 3rd exposes
Gas first 9, it is described to be respectively arranged in the first air-water contact area 2 of ozone contact tank, the second air-water contact area 5 and the 3rd air-water contact
The bottom in area 8, wherein the first aeration head 3 and the second aeration head 6 are connected with ozone generator 15, the 3rd aeration head 9 and ozone
It is connected at the top of contact chamber with jet aerator 12, the 3rd aeration head 9 passes through jet stream by the use of ozone contact tank tail gas as source of the gas
Aerator 12 blasts the 3rd air-water contact area 8.Since the utility model only launches ozone to first, second air-water contact area 2,5,
In first, second reaction zone 4,7 unreacted tail gas（It is only tail gas main source herein, naturally it is also possible in whole system
Tail gas）3rd air-water contact area 8 is introduced by the 3rd aeration head being connected with jet aerator 12.Therefore same amount ozone with
The contact area of waste water and time of contact are greatly improved, and the dissolution rate and reactivity of ozone have also obtained very big promotion.
Further, in the system, first aeration head 3 is identical with the aeration quantity of the second aeration head 6.
Further, in the system, the 3rd aeration head 9 passes through pipeline and 7 top of second reaction zone and jet aerator 12
It is connected.
Preferably, there are two breather valve 13 is set, respectively it is arranged at the first breather valve and the 3rd of the second reaction zone 7
Second breather valve at 10 top of reaction zone.The operation principle of breather valve is as follows：When the make-up gas in system, its upper part gas
When the pressure rise in space reaches the operation positive pressure of breather valve, pressure valve is open-top, gas from breather valve expiratory port escape, when up to
During to operation negative pressure, the negative pressure valve of breather valve is open-top, and gas is supplemented into region, keeps the air-tightness of system.Due to the 3rd gas
The ozone amount of water contact chamber and the 3rd reaction zone is fewer, so first, second reaction zone can quickly enter the 3rd instead
Area is answered to be reacted, the air pressure at the top of the ozone contact tank is controlled effectively, and need not be set on each reaction zone
Put breather valve.Above-mentioned two breather valve is set, can reach accurate and adjust the air pressure of ozone contact tank, while office can be reduced again
Breather valve opening causes the discharge and destruction of tail gas when portion's air pressure is excessive, causes waste of energy.
Preferably, partition plate is provided between 7 and the 3rd air-water contact area 8 of second reaction zone, the partition plate lower end connects
The ozone contact tank bottom is connected to, the partition plate upper end is extended at the top of the ozone contact tank, in close 3rd gas
An opening is offered at 8 liquid level of water contact zone.
Since the utility model only launches ozone to first, second air-water contact area, in first, second reaction zone 4,7 not
The tail gas of reaction（Tail gas main source is only described here, naturally it is also possible to for the tail gas in whole system, after do not repeat）Pass through
The 3rd aeration head 9 being connected with jet aerator 12 introduces the 3rd air-water contact area 8.Therefore contact of the ozone of same amount with waste water
Area and time of contact are greatly improved, and the dissolution rate and reactivity of ozone have also obtained very big promotion.
And the first breather valve and the second breather valve by being arranged at 10 top of the second reaction zone 7 and the 3rd reaction zone
The exhaust positive pressure and intake negative-pressure of first, second reaction zone 4,7 and the 3rd reaction zone 10 are controlled, maintains the pressure of whole system
Balance and safety.When the pressure in region is within the control operation pressure limit of breather valve, breather valve does not work, and keeps smelly
The air-tightness of oxygen contact chamber.And due to being provided with partition plate between 7 and the 3rd air-water contact area 8 of second reaction zone,
An opening is offered at 3rd air-water contact area highest liquid level.By the way that the opening is set to make first, second reaction zone the 4,7 and the 3rd
The tail gas of reaction zone 10 can directly escape into more freely the 3rd air-water contact area 8, avoid first, second reaction zone, 3 top air pressure
The discharge and destruction for carrying out tail gas are directly opened when excessive by breather valve, causes waste of energy.
When first, second breather valve reaches operation negative pressure, negative pressure valve is open-top, first, second air-water contact area 2,5 supplement
During ozone, during the pressure rise of 7 upper gas space of the first reaction zone 4 and second reaction zone, due in the 3rd air-water contact area 8
Ozone amount is few, and for second breather valve still in negative-pressure operation, the pressure valve of the first breather valve is not open-top, the first reaction zone,
Second reaction zone 4, the opening of gas from the partition plate on 7 tops escape into the 3rd air-water contact area 10, and pass through jet stream and expose
Mechanism of qi 12 accelerates its flowing, dissolving and reaction in the 3rd reaction zone 10；When first, second breather valve reaches behaviour again
When making negative pressure, negative pressure valve is open-top, and ozone enters first, second air-water contact area 2,5, and ozone is cycled again by after system consumption.
Only when first, second breather valve reaches operation positive pressure simultaneously, gas is just escaped from first, second breather valve, passes through tail gas
Row is into air after destructor 14 is destroyed.
Therefore, compared to the prior art, the utility model greatly improves contact area and the contact of ozone and contact chamber
Time improves rate of ozone dissolution and reactivity.According to the various factors relation for influencing rate of ozone dissolution and reactivity, input
Condition includes：Input appearance and size, contact method, treatment conditions, ozone injection condition of contact chamber etc..If the needs of ozone
In the case that amount is certain, when other conditions are identical, using the system, occurrence quantity and generation energy for required ozone generator
Power requirement will substantially reduce, and the quantity and damage of facilities Capability Requirement simultaneously for vent ozone destructor will also substantially reduce.Therefore
And the system, by promoting the absorptivity and reactivity of ozone, the utilization ratio of ozone is effectively improved, reduces energy consumption, on an equal basis
In the case of processing requirement, effectively realize the cascade utilization of ozone, reduce ozone injected volume.Reduce ozonation technology simultaneously
Relevant device construction cost and operating cost and reduce vent ozone destructor load and number of devices input.It reduces
Operation ozone contact tank and the wasting of resources generated and unnecessary expenditures, have potential economic serviceability, simultaneously help
Water factory obtains more good resource, environment, social sustainable development.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover among the right of the utility model.
