The porous piece (11) (11 ′) and the grill case (7) are interposed so that a pressure gauge connecting hole (13) and a gas nozzle (14) are provided at the front of the grill case (7) on the inlet (4) side. Configuration of the combined mixer 1.

In another embodiment of the present invention, the stacked grille layer 6 is formed without forming the space portion 8 between the upper grille 6 and the upper grille 6 layers in the grill case 7. It consists of stages, and between the grill layer and the grill layer from the inlet (4) to the outlet (5) is interposed between the integrated diaphragm (10a) (10b), respectively, and then the inner diaphragm (10a) on the inlet (4) side ( 10b) forms a plurality of through holes 10c so that the liquid and gas introduced therein are mixed and moved while passing through the upper and lower grill layers, and between the diaphragms 10a and 10b where no through holes are formed when passing through the partial grill layer. A configuration of the mixer (1) adapted to mix mixing while moving to each layer of grill (6) located therein;

In another embodiment of the present invention, the grille 6 is formed in a single layer in the grill case 7 so that the liquid and gas introduced from the inlet 4 are mixed while moving in a single passage and discharged to the outlet 5. Configuration of the combined mixer 1. Reference numeral 15 denotes a pedestal, and 16 denotes a bulkhead which partially blocks unnecessary space for saving material.

The mixer 1 of the present invention configured as described above is installed as a water treatment plant, a wastewater treatment plant, a fish farm, an industrial chemical mixer, and the like as shown in FIG. 6 to mix and mix a liquid and a gas, a liquid and a liquid, a chemical and a chemical. For example, when the liquid and gas are mixed, the liquid is introduced into the connection socket (3) on the inlet (4) side of the mixer (1) and then moved through the porous piece (11) to the hexagonal grill (6) and at the same time the grill case. (7) The gas is injected from the gas nozzle 14 installed so that the exterior (2) penetrates on one side of the front surface and passes through the hexagonal grill (6) layer with the liquid.

The first mixed liquid and gas are collected again in the space part 8, and then passed through each of the grill layer passages stacked in two stages with intervening plates 10 and 10 ', respectively. The liquid and gas are discharged to the outlet (5) of the connection socket (3 ′) by the secondary mixing mixing at the y part, since they are moved in a small cycle curve in the ladle grille. As described above, the liquid and gas passing through the grill case 7 pass through the upper portion of the grill, are collected in the space 8, are compressed and mixed, and then mixed and mixed again in the three grill passages respectively stacked. When gas, liquid and liquid, chemicals and chemicals are mixed, the contact area is increased to achieve perfect mixing.

The theoretical basis applied to the mixer 1 of the present invention made as described above can be interpreted as Lewis' two-filem theory.

dm / dt = KgA (Cs-C) --------------- ①

(dm / dt: mass transfer rate, Kg: diffusion coefficient of gas, A: area where gas diffuses through it, Cs: saturation concentration of gas in solution, C: concentration of gas in solution)

① dm / dt = V × dc / dt, V × dc / dt = KgA (Cs-C)

(V × dc / dt: rate of change of concentration, Cs-C: deficiency until saturation)

As can be seen from the equation, the mass transfer rate can be increased by maximizing the contact area of the substance to be mixed compared to the diffusion coefficient and saturation deficiency of the gas. It is possible to apply. That is, even in the same phase or in different phases, materials having high reactivity may maximize the contact area of materials to be mixed in the mixing process in order to increase the reaction speed and minimize the deviation.

According to the above formula, the mixer of the present invention is to have a maximum contact area at a short distance by stacking hexagonal grilles in order to maximize the contact area, so that the material is finely pulverized and then stabilized through uniform mixing. Mechanism to be mixed was allowed to proceed in the enclosed space of the grill case (7).

The present invention thus formed the grill (6) in a hexagonal multi-structure and can be selectively made in manufacturing the height, side length, width, etc. depending on the intended use, so that the number of layers of the laminated grill also corresponds to the capacity of the mixture quality It can be stacked in a single layer to multiple layers, and between the stacked grill and grill layer, plates 9 and 10 are installed to form a mixing mixing passage.

As another embodiment of the present invention, the diaphragm 10a (10b) provided between the stacked grill layer and the grill layer in the mixer case (1) grill case (7) of FIG. After the formation, a plurality of through holes 10c are formed in the front concave diaphragm so that the liquid and gas are mixed as a whole by moving up and down through the plurality of through holes 10c at the front part of the grill layer, and a plurality of through holes 10c are formed. From the non-xy part, each moving passage is formed so that the liquid and gas are finely crushed and mixed again when moving to achieve stabilization.

As another embodiment of the present invention, the mixer 1 of FIG. 5 is formed to form a single layer of the number of grill layers installed in the grill case 7 to be used when mixing a small amount of material.

In addition, the gauge connection hole 13 formed at the upper end of the mixer 1 inlet 4 of the present invention is equipped with a pressure and flow rate gauge, and a gas supply tank and a gas gauge are connected to the gas nozzle 14 at the lower side. .

Referring to the field of use of the mixer 1 of the present invention made as described above are as follows.

Example 1) Field of application: for the management of dissolved oxygen in fish farms, ② Condition: seawater consumption 250㎥ / hr, raw water D.O → 7.4 ③Place: the material for bathing ground in Tongyeong-gun, Gyeongnam,

It is difficult to maintain the dissolved oxygen level necessary for physiological activity in the breeding tank where the large amount of fish is fished in the fish farm. Therefore, it is necessary to continuously supply a large amount of oxygen while supplying a huge amount of seawater to replace it. It was.

In the above situation, the mixer of the present invention is equipped with oxygen to supply water to the tank by mixing oxygen together when supplying seawater, and thus, sufficient dissolved oxygen can be maintained in the tank, so that the activity of meat becomes more active than before, and the amount of seawater used Not only can it be reduced to less than half, but even if a large amount of fish is operated closely, the physiological activity of meat is not impeded at all, and sufficient activity is provided even if only 20% of oxygen is supplied based on 100% of the existing oxygen supply. there was.

Example 2) Application area: for the management of dissolved oxygen in fish farms, ② Condition: seawater consumption 260㎥ / hr, raw water D.O → 7.4, ③Place: Busan, Busan

As a fish farm similar to Example 1 above, red tide creatures frequently appeared in local conditions. In this case, we have experienced a lot of deaths in the situation that we will stop supplying seawater. However, using the mixer of the present invention, when oxygen is supplied and mixed together when supplying seawater, and oxygen is supplied using seawater in a tank in a situation where the supply seawater is stopped, sufficient dissolved oxygen can be maintained, while the existing oxygen supply is based on 100%. It supplied about 20% oxygen and no meat was killed. Therefore, it was possible to operate the fish farm without any problem in the survival of the meat until the surrounding red tide disappeared.

Example 3) Application: Oxygen supply for drainage treatment of chemical plant, ② Location: Yeosu Hwachi-dong, Yeosu, Korea

In order to treat the high concentration of wastewater discharged from the chemical plant here, it was operated by the oxygen aeration method and used 200㎥ / hr of oxygen to operate it, and it was expensive. Therefore, as a result of supplying oxygen by supplying the mixer of the present invention to the return sludge line, dissolved oxygen was increased by 10 ppm or more, and the oxygen consumption was about 20% of the existing consumption.

As can be seen in the above embodiment, when the mixer of the present invention is used, the liquid and gas to be mixed, the liquid and liquid, chemicals and chemicals, etc., increase the contact area when the mixer passes through the grill, thereby increasing the fine size in the grill layer. By pulverizing and mixing in a water treatment plant, waste water treatment plant, fish farm, etc., it is possible to maintain the dissolved oxygen amount for a long time.

The mixer of the present invention as described above is compact in size, ② light in weight, ③ inexpensive to install, and ④ easy to attach and detach by mixing the connection socket with the inlet and outlet of the mixer. In the grill layer, the length of the contact area made when mixing objects such as liquid and gas is mixed to a minute size, so that dissolved oxygen is maintained in the treated water for a long time, so that oxygen is supplied to the purified water treatment plant, the wastewater treatment plant, and the fish farm. Only about% can get enough effect.
