Description

Ozone water immersion-washing device

Art

The present invention relates to Ozone Water occur and embathe decontaminating apparatus, embathe sterilization especially for food and utensil, and health care aspect, include water tank and ozonator, processed thing is immersed in water, and ozone is added to the water constantly.

Background technology

Ozone is the very outstanding chemicals of a kind of characteristic, can not only kill various bacterial virus instantaneously, can also the harmful chemical pollutant of resolution process.Because the ozone short time is reduced to oxygen, without any residue, do not cause secondary pollution, thus ozone is called as safest " green " disinfectant, is widely used in industrial water treatment equipment.Civilian in family, and health care aspect, people have carried out many trials.There is a kind of product, similar aquarium oxygenation is the same, be connected in series an ozonator in pipeline between air pump and aeration head (or plate), aeration head is at water tank bottom, and this product technology principle comes from aeration oxygenation (the adding ozone) technique in Treatment of Industrial Water.

In aeration system, underwater bubble diameter is very large, this is because the surface tension that bubble will overcome water departs from from aeration head (or plate), what lean on is the buoyancy of bubble, surface tension is directly proportional to the first power of the diameter of bubble, and buoyancy is directly proportional to the cube of bubble diameter, and no matter how little the aperture of solarization air cap have, bubble must grow to certain yardstick and could depart from from aeration head, becomes the bubble freely floated.Time of contact and the contact area of the efficiency of ozone dissolved in water and bubble and water are directly proportional, the diameter of contact area and bubble is inversely proportional to, and bubble is less, and specific surface area is larger, aeration system can not increase specific surface area, can only by increasing the dissolved efficiency improving ozone time of contact.In commercial Application, Aeration tank reaches several meters deeply, tens of rice has, and make bubble at the bottom of pond, float to the time that the water surface has several minutes, the time of staying that namely gas ducks in drink reaches several minutes, can realize ozone dissolved efficiency like this and reach 70 ~ 80%.But in above-mentioned household products, the degree of depth of water tank just 30 centimetres at most, adopt aeration method in water shallow like this, ozone dissolved efficiency is extremely low, and the ozone of more than 90 percent has all been discharged in air.In air, ozone concentration is too high, harmful, and there is relevant ozone environment concentration standard in country.Thus in domestic small sized product, adopting aeration method to be added to the water by ozone, is a kind of know-why just irrational method, and this is the main cause that never popularizes of this kind of product namely, in addition, this product in use and the dependable performance of product stablize aspect also have many problems.

Summary of the invention

The present invention is directed to the problem of this product above-mentioned, a kind of product of brand new is proposed, adopt the impeller-driven water of high-speed rotation, produce strong turbulent flow whirlpool, rely on strong turbulent flow whirlpool to be pullled by the bubble in water and be shredded into more more tiny bubbles, obtain higher gas-water contact area, thus realize high ozone dissolved efficiency.Adopt water tank and base can the structure of convenient dismounting, make user easy to operate, and safe and reliable.

Technical scheme of the present invention is: critical piece includes: water tank, base, impeller, motor, ozonator, also has power supply electric component.Processed thing is immersed in the water in water tank, motor driven impeller rotates, vane drive water sport on impeller, produces strong turbulent flow whirlpool, is pullled by the bubble ozoniferous be mixed in water and is shredded into more more tiny bubbles, obtain high gas-water contact area, realize high ozone dissolved efficiency, feature of the present invention is: motor is in base, and impeller is in water tank, impeller is furnished with pump case, forms water pump structure; Water tank is placed on base, and water tank can take off from base easily and place; Driving connection between impeller and motor have employed shaft coupling has axle to drive connection, or non-contact magnetic force drives connection.

So-called whirlpool, be exactly in the velocity field of the fluid of motion the speed of each point inconsistent, there is speed (vector) gradient, turbulent flow whirlpool intensity is high, be exactly that velocity gradient is high, under having bubble to exist, the speed of bubble surface each point is consistent in the speed of this point with fluid (water), but each point fluid (water) speed is inconsistent, consequently spherical bubbles is pullled elongated, thinning, under the effect of turbulence pulsation, a bubble is shredded into two or more bubbles like this, that is the surface tension of water is overcome, the strength of being torn up by underwater bubble is whirlpool (velocity gradient), velocity gradient is larger, namely whirlpool is stronger, mastication forces is also larger, then can tear into less bubble, underwater bubble is less, quantity is more, the area that gas contacts with water is larger, the efficiency that ozone gas is dissolved in water is higher.

Impeller and pump case form water pump structure, during the impeller-driven water sport of rotation, can turbulization whirlpool, and wheel speed is higher, and the flow of pump is lower, and turbulent flow whirlpool intensity is stronger.Impeller pump has three kinds of versions, and one is axial-flow type, and two is centrifugal, and three is eddy current types.The whirlpool intensity that axial-flow type produces is minimum, from topology layout, is not also suitable in the present invention.Centrifugal and eddy current type topology layout is applicable to the present invention, and both compare, and in turbulence type pump, turbulent flow whirlpool intensity is the strongest.What the gas-liquid mixing pump in commercial Application adopted is exactly turbulence type pump structure, and underwater bubble diameter is little of 20 ~ 30 μm, and ozone dissolved efficiency can reach 98%.

Compare with aeration method, the method that the present invention adopts, can by improving wheel speed, reduce the flow of pump, adopt turbulence type pump structure, enough strong turbulent flow whirlpool can be obtained, make the bubble being mixed in water enough little, can realize being applicable to the civilian and health care aspect of family, in the water tank of water depth deficiency 30 centimetres, obtain ozone dissolved efficiency that is sufficiently high, that can meet the demands.
