Description

A kind of ozone generating-device for water process

Technical field

A kind of ozone generating-device is the utility model is related to, particularly for the directly electric discharge generation in the solution of water process The ozone generating-device of ozone.

Background technology

It is colourless gas under ozone normal temperature, there is one special careless fishy smell, there is an extremely strong oxidability, stability extreme difference, Oxygen can be voluntarily decomposed under normal temperature.Ozone has been widely used as disinfectant tool, not only can be with the various bacteriums of quick inactivating And the disinfectant such as virus, the chlorine that killing effect is also commonly used more than traditional water process mode and medically is far better.Ozone can For the sterilizing of the food such as water fruits and vegetables, meat, fresh-keeping, for the purification to air, deodorization etc..Ozone is as oxidability One of most strong oxidant, moreover it is possible to remove the heavy metal ion such as manganese in sewage, lead, cadmium, mercury, and oxidation Decomposition is many poisonous has Harmful organic matter and inorganic matter, has a wide range of applications in fields such as water process, especially deep to colourity, foul smelling difficult degradation Waste water action effect is more obvious.Ozone will not produce secondary pollution due to turning into oxygen after decomposition.In many countries, ozone It is widely used in sterilizing the fields such as drinking water, purification of air, food processing, health care, aquaculture.Such as American-European countries Waterworks has reached popularity using ozone, and mineral water, pure water producer are nearly all equipped with ozone devices；The U.S. is from upper Century 70 just starts with Wastewater Treatment by Ozone, primarily to sterilization, removal pollutant, decolouring etc. reach Discharge standard；It is Japanese then used as reclaimed water after in water-deficient area, sewage is handled by the use of ozone；The country such as U.S., day, moral, method is in recent years All to establish large-scale ozone sewage treatment plant.

Because ozone is a kind of unstable gas, it is impossible to storage transport, thus ozone must be made using scene It is standby, the method for artificially generated ozone, mainly there are electrochemical process, photochemical method and electrion process.Electrochemical process is to utilize direct current Power supply is electrolysed oxygen-containing electrolyte（Pure water）Ozoniferous method is produced, this generator can produce the Ozone Water of high concentration, manufacture Cost is low, using with it is easy to maintenance, but can not do that big, electrode life is short, ozone is not easy to receive due to ozone output be present The shortcomings of collection, its purposes scope are restricted.Photochemical method is to promote oxygen molecule to decompose using ultraviolet and aggregate into ozone Method.High-voltage discharge method is that natural imitation circle thunder and lightning produces ozoniferous method, by artificial alternation high voltage electric field in gas The electric discharges such as middle generation corona, electric arc, spark, the oxygen molecule in air is ionized into single oxygen atom and aggregate into three through collision The ozone molecule of atom.The ozone generator use of this electrion type is most wide, efficiency highest, water treatment field it is existing compared with More applications.

In the case history of current water process, be typically passed through in ozone generator air and discharge obtain ozone, Imported again through piping in pending solution.The life-span of most of active oxygen is shorter in active material caused by electric discharge, such as smelly Oxygen can produce after pipeline flow decomposes equal loss, and hydroxyl radical free radical OH life-span only in nanoseconds magnitude, is migrating Easily decay or wither away with diffusion process, so as to which the reduction of ozone isoreactivity content of material causes to utilize after piping transmits Efficiency reduces and adds power consumption.And it is distributed in the solution not due to range of scatter very little after ozone importing solution , cause disposed of in its entirety effect not ideal enough；Due to ozone generator and pending solution it is relatively independent cause equipment complicated and Space-consuming is larger, and for discharging, stronger reactor also needs matched cooling system because temperature is higher.

Also have directly to discharge in some water at present and carry out the example of water process, active material can be improved to a certain extent Utilization ratio, but be typically directed the air into aerator in solution, cause air in region of discharge skewness and discharge Region is smaller, less efficient.Therefore for having the shortcomings that water process ozone generating-device at present, it is necessary to a kind of new, high Effect, simple processing unit and processing system.
