Description

Ultra-miniature gun generator {omitted}

The present invention relates to an ultra-micro bubble generator for water treatment, and more particularly, to a bubble generator that generates high-density ultra-compact bubbles in a short time by applying compressed air having a higher pressure to a pressurized water at a constant pressure.

In the prior art, for example, a device for generating bubbles in a pressurized tank, for example, in the pressurized pump, compressed air is directly injected into the feed pipe from the outside while the raw water is transferred to the pressurized tank through the feed pipe. After the transfer, bubbles are generated and discharged while staying in the pressurized tank for a long time. By injecting the compressed air directly into the injection pipe, the dispersion of the compressed air is delayed and it takes time to mix with the pressurized water. The longer the time, the longer the pressure tank is as long as the residence time is long, and has a difficult problem to ultra-fine bubbles.

In order to solve the above problems at once, the present invention disperses and presses compressed air having a higher pressure into the mixing pipe by pressurized water at a constant pressure, thereby allowing instant mixing processing in the process of passing the pressurized pipe at a high concentration in a short time. It is an object of the present invention to produce and discharge an ultra-fine strength cloth of a small size and to provide a compact and highly efficient device.

The steel plate is angled at 90 °, and this mixing bracket is packed with steel rods of a certain length in a number of different directions, bonded and fixed in different directions, and filled with pressure in the mixed pipe (4, 5) and compressed air. Is instantaneously mixed, dissolved, and processed, and FIG. 4 is a compressed air dispersing device that distributes and intrudes compressed air, which is built in the mixing pipe 4 · 5, into a compressed air, and to a compressed air inlet A-A-1. The device is constructed by being connected and connected to an external compressor.

The operation of the embodiment configured as described above will be described.

When bubble water is supplied from the inlet pipe 2 while the pressurized pump P is operated and rises to a predetermined pressure, the dispersing device 17 in which the compressed air of the air pressure one step higher than the pressurized water is built into the mixing pipe 4 · 5 Compressed air pressurized into the pressurized air is dispersed and pressurized by compressed air in the fine holes 18, and the compressed air pressurized by the dispersion is mixed with the bubble water pressurized by the pressurized pump P and the built-in mixing bracket 16 After passing through the mixing bracket, the compressed air and the bubble water injected into the compressed air are mixed, dissolved, processed, and transferred to the control pipe (6), where the compressed air is compressed without being mixed, dissolved, or processed. Compressed air, which is not mixed, dissolved, or processed, is compressed and pushed up by the air vent (14 · 14-1) attached to the upper part of the control pipe, and the air vent is operated to discharge to the outside. Only the mixed, dissolved, and processed bubble water is pumped through the both feed pipes (7) to the primary pressurized pipe (8), and then pressurized again in the pressurized pipes, and again through both feed pipes (9). The final pressurized water is pressurized to the secondary pressure pipe 10 and finally pressurized, and the final pressurized bubble water is pumped to the positive pressure discharge valve 12 through the discharge pipe 11, and the ultra-fine strength bubble is opened as the constant pressure discharge valve is opened at a predetermined pressure. Is discharged into the water, so it is used as an ultra-fine foam generator in the flotation separator for water treatment.

The bubble water flows into the inlet pipe, is processed into an ultra-fine fabric, and discharged is very short, and a feature of this device is to discharge a high concentration of ultra-fine fabric.

Since the present invention discharges a high concentration of ultra-small density cloth in a very short time, the device can be miniaturized and very advantageous for the production of a large-capacity treatment device, which can be used for water and sewage facilities.
