Abstract

The invention provides a device for preparing micro-bubbles through compressed fresh water or seawater. The device consists of a water inlet pipe as shown in figure 1-(1) and two semi-circle devices as shown in figure 1-(2), a cylindrical device as shown in figure 1-(7) which connects the water inlet pipe and the two semi-circle devices, and a micro-bubble (MNB) forming part as shown in figure 1-(4). Water rotates in a container with a super high speed after being pressurized by a water pump; the centrifugal action of the water divides the part inside the container into a circumferential liquid zone and a central gas zone and discharges the gas and liquid through two discharge holes (4); and the gas is cut off and crushed to form the micro-bubbles (ultramicro-bubbles) on the contact surface between the liquid injection pressure inside the container and the external water pressure. The device can directly pump gases in nature (air, oxygen, ozone) into the water pump, thereby having convenience, high economical efficiency and practicability.

Description

High-speed cyclic gas-liquid mixing type micro-bubble generation 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. 3), 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 two hollow C shape pipes have improved liquid greatly, improved 25% compared with former fine foam incidence.3, because of having adopted the mode that is provided with air leading-in conduit at the water pump suction pipe place.Avoided the out of order situation of air conducting tube as Fig. 3-(8) 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

Cause has had high-speed cyclic condition 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 of Fig. 1-(6), makes being cut off of banded gas portion such as Fig. 1-(5) continous-stable.A large amount of micro-bubbles has taken place in the result.The generation diameter is the foam of 5nm～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 as needing the large-scale device of configuration, that water pump also needs large-scale joining, so cost can improve.Therefore, recommend to the utmost, raise the efficiency by increasing number with small-sized.

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