High-concentration oxygen-dissolving apparatus using ultrasonic waves

摘要

The present invention relates to a high-concentration oxygen-dissolving apparatus using ultrasonic waves. More particularly, the present invention relates to a high-concentration oxygen-dissolving apparatus using ultrasonic waves in which, when liquid is introduced via an inlet port, a sediment filter filters out foreign substances, a pre-carbon filter filters out harmful chemical substances, a UF membrane filter filters out impurities, a post-carbon filter filters out gas components and odorous components, the filtered liquid is stored in a storage tank, the liquid stored in the storage tank passes through a cooling device to be cooled to a low temperature, the liquid compressed to high pressure by means of a high pressure pump and a Venturi tube is introduced into an ultrasonic wave irradiating unit, oxygen is dissolved into the liquid by ultrasonic waves irradiated from the ultrasonic wave irradiating unit, the liquid flows to the storage tank through a flow pipe, and the liquid having an oxygen concentration higher than a predetermined level is discharged through an outlet pipe.

1. A high-concentration oxygen-dissolving apparatus using ultrasonic waves in an apparatus dissolving a high concentration of oxygen into liquid, comprising:
an inlet port (10) which receives liquid and has an inflow adjusting valve (16); a sediment filter (11) filtering foreign substances contained in the liquid flowing in through the inlet part (10); a pre carbon filter (12) connected with the sediment filter (11) for filtering a to harmful chemical substance contained in the liquid; an UF (Ultra Filtration) membrane filter (13) connected with the pre carbon filter (12) for filtering impurities dissolved in the liquid; a post carbon filter (14) connected with the UF membrane filter (13) for filtering gas components and odor components; an injection port (15) connected with the post carbon filter (14) for injecting liquid into the storing tank (20) which stores liquid and having a water level adjusting part which constantly adjusts the level of liquid; a temperature adjusting part (21) installed at an outer side of the storing tank (20) for setting the temperature of the storing tank (20); a D.O. (Dissolved Oxygen) meter (23) installed in the interior of the storing tank (20) for measuring the amount of oxygen dissolved in the liquid of the storing tank (20); a discharge tube (24) which is installed at a lower side of the storing tank (20) and has a discharge valve (22) through which the liquid of the storing tank (20) is discharged, thus adjusting the amount of the discharging liquid; a cooling apparatus (50) cooling the liquid to a low temperature when the liquid discharged through the discharge tube (24) passes; a high pressure pump (60) which transfers the liquid cooled in the cooling apparatus (50); an over oxygen return tube (64) connected with the high pressure pump (60) and the upper side of the storing tank (20) for inputting over oxygen, which is not dissolved in the storing tank (20), into the high pressure pump (60); a Venturi tube (80) connected with the high pressure pump (60) for discharging the liquid which is discharged from the high pressure pump (60); a pressure adjusting part (63) installed between the Venturi tube (80) and the high pressure pump (60) tot adjusting the pressure of liquid; an oxygen injection tube (70) connected with the Venturi tube (80) for injecting oxygen; an ultrasonic wave projection part (40) connected with the outlet port of the Venturi tube (80) and enhances the solubility of the oxygen and liquid by projecting ultrasonic waves toward the passing liquid and helps the passed-by liquid to flow into the storing tank (20); a flow tube (90) connected between the ultrasonic wave projection part (40) and the storing tank (20) and has a liquid pressure gauge (91), a decompression valve (92) and a flow adjusting valve (93); and a discharge tube (30) which is installed at a lower side of the storing tank (20) and discharges liquid to the outside after measuring the concentration of the oxygen dissolved in the liquid using the D.O. meter and has an ozone filter (32) for filtering ozone contained in the liquid and a solenoid valve (31) for opening and closing the liquid discharge.
