Abstract

PURPOSE:To prevent the increase in the particle size of air bubbles, by providing a perforated pipe, which has a large number of fanwise fine apertures and is closed at the leading end thereof, in communication with the jet orifice of a jet nozzle. CONSTITUTION:In an air mixed liquid generation part A, water flowed into a liquid chamber 20 is converted to bubbles mixed water by air injected from an air nozzle 10 and flowed out to an outer cylinder 60 while passed through a large number of fanwise fine apertures 52. Subsequently, bubbles water flowed out to the outer cylinder 60 is flowed into the first pressure regulation chamber 70 of a bubbles water storate part C without generating the mutual coalescence of air bubbles caused by the generation of turbulent streams because there is no barrier plate nor a corner parter in a flowline. In the pressure regulation chamber 70, bubbles water flowed into the bottom part 71 thereof from the outer cylinder 60 passes through the top part 72 thereof to be successively sent to a pressure regulation tank 80.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a bubble liquid generation device, particularly a bubble liquid generator used in a wastewater treatment device for treating industrial wastewater, sewage generated in a ship's engine room, etc., an oil-water separation device, etc. The present invention relates to a device for generating water.

Although the prior art was invented and succeeded in continuously generating a bubble liquid, there was a drawback that the bubbles in the bubble liquid recombined and the bubble particle size became large.

Problems to be Solved by the Invention Therefore, the present inventor succeeded in preventing the bubbles in the bubble liquid from recombining and increasing the bubble particle size at the stage of producing a bubble liquid with a fine bubble particle size. did.

Means for Solving the Problems Therefore, the present invention provides a porous tube with a closed tip, which has a large number of pores that widen toward each other, and communicates with the injection port of an injection nozzle that injects a gas-mixed liquid. An outer cylinder is provided that surrounds the outer periphery of the porous pipe and is formed so that the bubble liquid flowing out from the pores that widen toward the end of the porous pipe can flow smoothly into the next first pressure adjustment chamber without generating turbulence, Furthermore, a first pressure adjustment chamber is provided in which the bubble liquid flowing out of the outer cylinder is allowed to flow into the bottom and flow out from a large number of diverging multi-pores provided at the top, and the bubble liquid flows out from the top of the first pressure adjustment chamber. The bubble liquid can be stored in a pressure adjustment tank.

Function: When the gas mixture liquid generated from the injection nozzle passes through the perforated tube and the multi-pores that widen toward each other at the top of the first pressure adjustment chamber, the bubble particle size is made finer, and the finer bubbles are Since it is designed to diffuse immediately, there is no risk of bubble particles recombining with each other, and since the outer cylinder from the porous pipe to the first pressure adjustment chamber does not generate turbulence, the air flows inside the outer cylinder. In the bubble liquid, there is little risk of bubble particles recombining with each other, and the bubble liquid with fine bubble particle size is continuously and stably stored in the pressure adjustment tank.

Embodiment The device of the present invention includes a gas mixed liquid generating section A1 a bubble liquid stabilizing section B.
And a bubble liquid storage section C is maintained. The gas mixed liquid generating section A includes a liquid chamber 20 formed on the outer periphery of a gas nozzle/L'lO1 gas nozzle/v10, and a liquid nozzle 801 having an injection port 81 facing the liquid chamber 20. 1'l
The gas-mixed liquid injection nozzle 40 is formed in communication with the liquid chamber 20 in the extending direction of the center line of the nozzle O [1]. The taper angle of the jet hole 11 of the gas nozzle/L/10 is α, and the horizontal distance from the taper part 41 of the gas mixture liquid jet nozzle/L/40 to the intersection point P with the inner circumferential surface of the nozzle 40 is the horizontal distance of the part 42. The distance is 14, and the intersection of the center line extension of the liquid nozzle 1lz80 and the center line of the gas nozzle/L'lO is 8
If the angle between − and the center line is q, the following relational expression is established.

10≦α〈80°, 1°≦β〈80°, α≧β, q≦9
0°, 0≦l l<L,, l12>O, l 8≧0.1
4≧0, l 5≧0, 20>β6〉I C-1
The corner 22 that transitions to 0 forms a smooth chamfer so that the liquid flows laminarly.

The reason why 1°≦α<80° is set in the above relational expression is that gases are mixed and fine bubbles are continuously generated. If the value of α is small, the air jet will be equal to the jet nozzle/l/40
It will penetrate through the hole without colliding with the inner wall of the hole. If the value of α is larger than 80″, there is a risk that the gas will not diffuse regardless of the value of α, and the flow will have a diameter that is approximately the same as the diameter of the pore portion 12 of the gas nozzle/l/10.

The reason for setting l°≦β≦80° is that even if the value of β is 4-4 degrees smaller than 1°, the generation of microscopic bubbles will be extremely small even if the value is larger than 80°. The reason why α≧β is set is that it is effective in generating bubbles while injecting the gas mixture liquid at an angle at which the air jetted from the jetting hole 11 of the gas nozzle μm0 collides with the inner wall surface of the jetting nozzle /l/40. It is from. Furthermore, the reason for setting 0≦Jl<L and e4≧0 is that the fluid flows while turning to the right or left in the diverging taper hole 41 of the injection nozzle/L'40, so at this time, the liquid and gas are Since the gas is stirred and mixed into the liquid, the efficiency is good, so the parallel part of e4 is provided, thereby forming an efficient laminar flow of the fluid at the inlet of the injection nozzle #40. Ru. Next, q≦90° and 15≧0 are set so that the liquid nozzle/l/80 is provided at the inlet of the injection nozzle 40 to help form an efficient laminar flow of the fluid. Also,
When e2〉0 and 8≧O, Shida is useful for forming a laminar flow of the fluid, same as the purpose of q≦90°, and the liquid fills the liquid chamber 20 and is injected from around the tip of the gas nozzle/L/10. This is because an average water flow to the nozzle 40 can be obtained. The bubble stabilizing part B is the injection port 41 of the gas-mixed liquid injection nozzle/L'40.
It consists of a porous pipe 50 that communicates with the porous pipe 50 and an outer cylinder 60 that surrounds the outer periphery of the porous pipe 50 and faces the next first pressure adjustment chamber 70. The porous tube 50 has a closed tip 51 and is provided with a large number of υ pores 52 that widen toward each other as shown in FIG. The pore 52 has a population diameter D larger than its population diameter d.
It is designed to prevent recombination and turbulence as much as possible, with the exit diameter being . The outer cylinder 60 is formed so that the bubble liquid flowing out from the pores 52 of the porous pipe 50 can smoothly flow out into the first pressure adjustment tube 70 without generating turbulence, and the flow path is free from corners and obstructions. The board has been removed. The bubble liquid storage section 0 consists of a first pressure adjustment chamber 7o and a pressure adjustment tank 80 surrounding the first pressure adjustment chamber 7o. First pressure adjustment chamber 7
0 allows the bubble liquid flowing out from the tip of the outer cylinder 6o to flow into the bottom part 71, and the top part 72 is provided with a large number of pores 720 which widen toward the end and are substantially similar to those shown in FIG. The pressure adjustment tank 80 has a bubble liquid outlet 81 located at a slightly higher position than the top 72 of the first pressure adjustment chamber 7o.

82 is the pressure regulating valve mounting screw hole, 88 is the surplus air overflow b.
The mounting screw hole 84 is a hole for mounting a pressure gauge.

Therefore, the gas nozzle/l/10 has pressurized air, the liquid nozzle 8
When pressurized water is supplied to the gas-mixed liquid generating section A, the water flowing into the liquid chamber 20 is made into bubble-mixed water by the air jetted from the gas nozzle (vlo), and the water flows through the porous holes p of the bubble-water stabilizing section B. It is fed into #50, passes through a large number of widening multi-pores 52, and flows out to the outside @60, but after passing through the pores 52, the bubbly mixed water becomes bubbly water with finer bubble particle size. However, in this case, since the pores have a cross section that widens toward the end, the bubbles are diffused and recombination of the finely divided bubbles is prevented. Next, the bubble water flowing into the outer cylinder generates turbulent flow because there are no baffles or corners in the flow path, and the first pressure adjustment ratio 70 of the bubble liquid storage section C is generated without recombining the bubbles. is flowing into the country. In the first pressure adjustment chamber 70 of the bubble liquid storage section C, the bubble water that has flowed into the bottom 71 from the outer cylinder 60 passes through the top 72 and is sequentially transferred to the pressure adjustment tank 80. When passing through the multi-pores 720, the bubble size in the bubble water becomes even finer, but at this time, since the pores widen toward each other and have multiple cross-sections, the bubbles are diffused and the fine-grained bubbles form one another. There is no fear of recombination. The bubble water with the fine bubble particle size is then transferred to the pressure adjustment tank 80.
It will be stored and supplied for various uses as needed.

Effects of the Invention As described above, the apparatus of the present invention makes it possible to continuously and stably generate bubble water while preventing the bubbles from recombining with each other during bubble refinement.
