Abstract

The present invention provides an equipment capable of making pressurized fresh water or sea-water into micronano foams. It is composed of water-intake pipe, two semicircular devices, cylindrical device connected with water-intake pipe and two semicircular devices and micronano foam formation portion. Its working principle is as follows: after the water is passed through water pump and pressurized, the water can be rotated at ultrahigh speed in a container, under the centrifugal action in the container interior a peripheral liquor band and a central air band are formed, and can be discharged by means of two discharge holes, the contact surface air of container interior liquid jet pressure and external water pressure can be broken and pulverized so as to form the micronano foams (ultramicrosmall air bubbles). Said equipment can directly pump the natural gas (including air, oxygen gas and ozone) into water pump, so that said equipment has convenient property, economical property and practicability.

Description

High speed rotary type gas-liquid mixed type micro-nano foam generating device

Though this invention is adopted is the process of chopping of spiraling among putative three foaming methods, and it further develops the old-fashioned process of chopping of spiraling and makes foam become refinement more.And be the device of input ratio that is easy to regulate the liquids and gases of institute's output.

There is following weak point 1 in former device (such as WO00/69550), because of not taking into full account the ratio of internal capacity and gas-liquid tap, so the bubble of output lacks uniformity.2, because of rotary speed slow, so be necessary to strengthen the amount of flow of air.3, because of must being furnished with air leading-in conduit (as the mode of Fig. 2), so in case at sea or when using on the rivers and creeks conduit damage is arranged, device will stop operation.Also have the part that is equipped with many, also undesirable aspect cost.

This device has improved shortcoming recited above.Concrete improvement is described as follows.1, suitable internal capacity and gas-liquid are divided the ratio of tap.2, because be provided with the rotary speed (rotary speed improves the ultra micro refinement that more can promote foam) that hollow C shape pipe has improved liquid, improved 25% compared with former fine foam incidence.3, because of having adopted the mode that is provided with air leading-in conduit at pump outlet.Avoided the out of order situation of air conducting tube of Fig. 2 mode.

This device handlebar air, ozone, oxygen etc. melt effectively in running water, dam, the rivers and creeks, city, the great river, functions such as littoral ocean can purify water, and improve the ecological environment, and improve the output of aquatic products industry and agricultural.Extensively admitted abroad.

Up to the present not only the liquid speed of gyration is low for micro-bubble generation device, and the size of blebbing amount and foam also has restriction.

This invention is mentioned water flow inside speed and is surpassed in the past more than 2 times.It plays a driving role in the oxidation that improves water.

This device can reduce energy expenditure (electrical equipment, chemical fuel etc.), and cost is obviously descended.

Because of being equipped with attached gas gatherer, so can might change into the existing high speed cut-out mode of spiraling (the gentle fluid separation applications importing of gas-liquid mixing importing type type) two kinds.At input oxygen, in the time of ozone etc., uses an accessory, make that (air pressure on the face of land 0.1013MPa{1kgf/cm2}) is all mutually from the pressure of air accumulator supply and face of land air pressure.

The specific embodiment

Fig. 1 is the principle key diagram of manufacturing installation.

Fig. 1-(A) figure is a side view, and the figure of Fig. 1-(B) is the sectional drawing of figure of Fig. 1-(A).

Cause has had the condition of spiraling at a high speed and gas, the difference in specific gravity of liquid, and liquid produces powerful centrifugal force, and gas produces powerful centripetal force and makes can separating of liquids and gases simultaneously.Also to produce great turning speed poor because of the front and rear part 10. of Fig. 1-(A), makes 9. being cut off of continous-stable of banded gas portion.A large amount of micro-nano foam MNB has taken place in the result.The generation diameter is the foam of 50nm～20 μ m near Fig. 1-(4), and is emitted the container outside.

Fig. 2 is meant the key diagram that gas discharge hole is held concurrently as the schematic diagram of gas input hole.

Use and the range of application explanation

Small-sized, medium-sized, large-scale plant all can be made, but such as the large-scale device of needs configuration, that Water pump also needs large-scale joining, so cost can improve. Therefore, recommend to the utmost with small-sized, Raise the efficiency by increasing number.

The present invention can be used for the pond, rivers and creeks, dam, marsh, the purification of water quality of coastal grade, various dirt Water treatment, water saving facility project. So device that is easy to promote because simple structure is with low cost.

Claims

1. micro-nano foam generating device is a kind ofly to be formed with a columniform container combination that links to each other with water inlet pipe by two hemispherical containers.A hollow C shape pipe Fig. 1-A-(3) is arranged (3`) at columniform inner face, respectively have a circular hole (MNB) Fig. 1-A-(4) to play ejection liquid, form the effect of micro-nano foam and air conduit at hemispheric two ends.(in a hole, finishing three phenomenon).

2. be a kind of hollow C shape pipe, it is water inlet pipe and hydrostatic column connecting portion two parts (hollow C shape pipes suitable for reading), and the area of plane of each part is all littler than the area of plane of water inlet pipe Fig. 1-(1).The area of plane summation of two parts of cause is less than the area of plane of water inlet pipe, so the gas liquid mixture that pressurizeed is managed Fig. 1-(3) by hollow C shape, (3`) back speed has improved 25%.

3. be the hole pattern 1-(4) that is positioned at two hemispherical container two ends, it is that the hole takes place micro-nano foam, can be used as the gas entrance hole again.Must be equipped with another accessory and import natural air, oxygen, ozone gas etc., and a large amount of micro-nano bubbles discharged from another discharge orifice.

4. be a kind of device that is different from international monopoly WO00/69550, be provided with air leading-in conduit, be not provided with the combination of the uniqueness of gas introduction tube separately at the nanometer generating means at pump outlet.The bubbles volume that this device produces is big, and is evenly, stable.
