Description

Novel jet flow adds coarse surface impacts ozone mixing equipment

Technical field:

The utility model relates to WWT ozone oxidation specific equipment field, is specifically related to novel jet flow and adds coarse surface impacts ozone mixing equipment.

Background technology:

1, ozone characteristics general introduction

Why ozone can be used as the medicament of the strong oxidation of WWT chemistry, and basic reason is the high oxidation potential that has because of ozone itself, and its potential level can be accomplished normal temperature and pressure and not add under the catalytic condition most of organic oxidising processs.In fact ozone contacts the back to accomplish the speed of oxidizing reaction very fast with organism, so the oxidation effectiveness of ozone will depend on basically that organic mixing contacts in ozone and the water.This relates to two of gas-liquids and mixes the mass transfer technology.

2, existing ozone hybrid technology brief introduction

First-generation Bubbling method: to be the ozone gas that produces ozonizer be passed into the bottom of oxidizing tower or oxidation pond through pipeline to Bubbling method, sends microbubble through the microvoid bubbler, bubble in the process that rises ozone solution in water.The efficient that adopts Bubbling method to mix ozone is generally 20%-30%.

S-generation fluid jet: fluid jet is that the air cavity in ejector forms negative pressure under the effect of high velocity jet, the inspiration ozone gas, and high velocity jet is pulverized ozone gas again, forms microbubble and fully contacts mixing with water.Adopt the efficient of fluid jet mixing ozone to be generally 25%-40%.

Third generation mixing pump method: mixing pump is generally eddy current type, in pump, forms negative pressure, and suction opening sucks gas (or liquid), and can carry out gas-liquid through the stirring of a plurality of impellers, and liquid liquid mixes.Common mixing pump generally is the Ni Keni mixing pump on the market.Adopt the mixing pump dissolved ozone efficient high, generally at 40%-70%.

The 4th generation the high efficient mixed tower: the material of this part generally also is difficult to find, so temporarily can't discuss its structure and performance, just claims that through relevant report its efficient will be higher than the mixing pump method, and equipment is less, is adopted by major companies such as coke coca colas.

3, impact jet flow

The impact jet flow technology is that particular fluid with specific objective ballistic process is taken place after spraying.About the research of jet impulse hybrid technology closely carry out in a lot of fields more extensive; Generally believe that its mixing efficiency is very high; And become the focus direction of present two phase hybrid technology researchs; But because the difficulty of shortage and the mathematical simulation of its guiding theory also is difficult to it is done the argumentation of system so far, but play a role in many fields as utilisation technology.The outstanding feature that this technology is generally acknowledged is that turbulent flow is strong, and Reynolds number is very big, moment the mass-and heat-transfer works very well.

4, the problem of existing ozone hybrid technology existence:

1, the mixing pump mode does not still have the other investment of big flow standardized product greatly at present, and the ozone addition is limited;

2, the high efficient mixed tower is owing to technical monopoly, and cost is higher.

The utility model content:

The purpose of the utility model provides novel jet flow and adds coarse surface impacts ozone mixing equipment, it have the mixing efficiency height, simple in structure, operation is convenient, cost of manufacture is low, be applicable to advantage such as the various water yields.

In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises water pump 1, ejector 2, ozonizer 3, pottery impact sheet 4, connects tail gas breaking plant 5, treat effluent mouth 6; Water pump 1 is connected with the top of ejector 2; Ozonizer 3 is connected with the trunnion place of ejector 2; Pottery impacts sheet 4 and is arranged on ejector 2 outlet vertical lower, connects the top that tail gas breaking plant 5 is arranged on the ozone mixing equipment, and treat effluent mouth 6 is arranged on the side top of ozone mixing equipment.

The utlity model has following beneficial effect:

1, one-piece construction is simple, and is easy to maintenance, and failure rate is low;

2, height and occupation of land are all very little, and cost is low;

3, conveniently amplify and dwindle, be applicable to the various water yield;

4, can adjust air input easily, the tolerance limit is much larger than air dissolved pump in addition;

5, possess the ozone mixing efficiency suitable under the same terms with air dissolved pump.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Embodiment:

Referring to Fig. 1, this embodiment adopts following technical scheme: it comprises water pump 1, ejector 2, ozonizer 3, pottery impact sheet 4, connects tail gas breaking plant 5, treat effluent mouth 6; Water pump 1 is connected with the top of ejector 2; Ozonizer 3 is connected with the trunnion place of ejector 2; Pottery impacts sheet 4 and is arranged on ejector 2 outlet vertical lower, connects the top that tail gas breaking plant 5 is arranged on the ozone mixing equipment, and treat effluent mouth 6 is arranged on the side top of ozone mixing equipment.

This embodiment is handled former water and is got into ejector through the water pump pressurization; Utilize the jet flow negative pressure principle to suck gas ozoniferous, at first carry out the first step and mix, reach the effect that the mm level mixes at ejector trunnion place; Ejector outlet vertical lower is provided with pottery and impacts sheet; The high speed impact collision is carried out on air-water mixture impact sheet surface under the surplus pressure effect, on impingement area(s), forms combined effects such as great randomness, Reynolds number, acceleration stresses, pressure, accomplishes most ozone and the mixing effect of handling former water; Afterwards, accomplish third stage hybrid reaction in the tiny bubble up-flow process.

This embodiment has following beneficial effect:

2, height and occupation of land are all very little, and cost is low;

3, conveniently amplify and dwindle, be applicable to the various water yield;
