Description

  The present invention relates to an ultrasonic air / water separator for separating a liquid from air / water by vibrating a collection vibration tube using ultrasonic vibration.

As a conventional air / water separator of this type, as shown in FIG. 3 , an adsorption mat 2 is mounted in a case 1, an exhaust pipe 3 is mounted on the upper end of the case 1, and a supply mounted on the lower end of the case 1. A device is proposed in which a gas supply device 5 is connected to the tube 4, and a waste liquid tube 6 is connected to the lower part of the case 1, and a waste liquid device 7 is connected to the waste liquid tube 6.

  In the conventional air / water separator configured as described above, the gas containing the mist supplied from the gas supply device 5 is adsorbed by the adsorption mat 2 in the case 1, and the mist adsorbed by the adsorption mat 2 is liquid. Although it is configured to be collected as a droplet from the waste liquid pipe 6 by the waste liquid apparatus 7, in this conventional example, since the adsorption mat 2 is mounted in the case, a high-pressure gas is supplied from the supply pipe. Otherwise, the adsorption mat 2 is not adsorbed, and because the adsorption mat 2 is used, there is a problem of chemical resistance of the adsorption mat 2, and the adsorption mat 2 used to some extent must be discarded. Therefore, there is a problem that the inside of the case 1 needs to be maintained because the suction mat 2 is used.

  The problem to be solved is that in the conventional air-water separator, in order to use the adsorption mat, the gas must be supplied at a high pressure, and the adsorption mat has a problem of chemical resistance. If the suction mat is used to some extent, it must be discarded, and furthermore, since the suction mat is used, there is a problem that maintenance inside the case is required.

In the present invention, a supply pipe connected to a gas supply device that supplies a gas containing liquid particles is provided at the lower end, an exhaust pipe that discharges the gas is connected to the upper end, and a collection attached to the inside of the case A vibration transmission plate having one end fixed to the collecting vibration tube through the side of the case, an ultrasonic vibration generating device fixed to the other end of the vibration transmission plate, and the ultrasonic vibration generation An oscillator connected to the apparatus, and transmits the ultrasonic vibration generated from the ultrasonic vibration generator to the collection vibration pipe through the vibration transmission plate, and one end of the supply pipe has the collection vibration It is mounted at the center of the pipe and separates liquid particles from the gas supplied from the supply pipe to which the gas supply apparatus is connected. The vibration generator includes a coupling horn and a dummy horn of a Langevin type vibrator. The vibration transmission composed of It is being sandwiched and fixed between the coupling horn and the dummy horn.

In the ultrasonic air-water separator of the present invention, a vibration transmission plate connected to the ultrasonic vibration generator is fixed to the side of the collecting vibration tube, and the ultrasonic vibration from the ultrasonic vibration generator is attached to the vibration transmission plate. When the ultrasonic vibration is transmitted to the collecting vibration tube via the center, the ultrasonic pressure is concentrated and synthesized from the outside to the center of the collecting vibration tube, so that the sound pressure at the central portion of the collecting vibration tube is increased. Therefore, the liquid particles contained in the gas supplied from the supply pipe concentrate in the vicinity of the supply pipe, and when the liquid particles become large, they fall along the supply pipe, and only the liquid particles are recovered from the waste liquid pipe of the case is, gas liquid particles have been removed has the advantage that Ru is exhausted from the exhaust pipe.

  In the present invention, the case is connected to a supply pipe connected to a gas supply device that supplies a gas containing liquid particles and an exhaust pipe that discharges the gas, and the collection vibration pipe is mounted inside the case, and the vibration transmission plate One end is fixed to the collecting vibration tube through the side of the case, the ultrasonic vibration generator is fixed to the other end of the vibration transmission plate, and the ultrasonic vibration generator is a horn that combines a piezoelectric vibrator with a metal block and a horn. The vibration transmission plate is sandwiched and fixed between the coupling horn and dummy horn of this Langevin type oscillator, and the oscillator is connected to the ultrasonic vibration generator and generated from the vibration generator. The ultrasonic vibration is transmitted to the collection vibration tube via the vibration transmission plate, and the liquid particles are separated from the gas supplied from the supply tube by the collection vibration tube.

  FIG. 1 is a side sectional view of an ultrasonic air / water separator according to an embodiment of the present invention. FIG. 2 is a plan sectional view of the apparatus shown in FIG. 1. An exhaust pipe 10 is attached to the upper part, and one end of the supply pipe 11 is attached so as to be inserted into the center of the collecting vibration pipe 9 through the lower part of the case 8, and a gas supply device 12 is connected to the other end of the supply pipe 11. One end of the vibration transmission plate 13 is fixed to the side portion of the collecting vibration tube 9, and the other end is mounted between the coupling horn 14a of the Langevin type vibrator 14 and the dummy horn 15, and the Langevin type vibrator 14 is connected to the coupling horn. 14a and the metal block 14b, the piezoelectric vibrator 16 is sandwiched, the oscillator 17 is connected to the piezoelectric vibrator 16, and the waste pipe 18 is connected to the lower part of the case 8, and the waste pipe. A waste liquid device 19 is connected to 18.

  In the ultrasonic steam-water separation device of this embodiment configured as described above, when the oscillation output is applied from the oscillator 17 to the piezoelectric vibrator 16 of the Langevin vibrator 14, the coupling horn 14a of the Langevin vibrator 14 is used. Since the vibration transmission plate 13 mounted between the dummy horn 15 vibrates and ultrasonically vibrates the collection vibration tube 9 in the case 8, the ultrasonic vibration transmitted to the collection vibration tube 9 is collected vibration. Since concentrated synthesis is performed from the tube 9 toward the center, the liquid particles in the gas supplied from the supply tube 11 are concentrated in the vicinity of the center of the collection vibration tube 9, and when the liquid particles are concentrated, the particles become larger. Since the mass increases and drops through the supply pipe 11 through the supply pipe 11, the dropped liquid drops accumulate in the lower part of the case 8, flow from the waste liquid pipe 18 to the waste liquid device 19, and are collected.

  Thus, in this embodiment, by transmitting ultrasonic vibration to the collection vibration tube 9, the sound wave concentrates at the center of the collection vibration tube 9, and the mist contained in the gas supplied by the concentrated sound wave Since the gas is collected into large droplets and the mass is increased, the gas falls into the case 8 and is recovered, and the gas from which the mist has been removed is exhausted from the exhaust pipe 10 at the top of the case 8, and the adsorption mat is not used. Since the gas supply has no pressure loss, there is an advantage that the supply pressure can be reduced, there is no problem of chemical resistance, industrial waste is eliminated, and maintenance in the case 8 is not required.

  In the above embodiment, an example using a Langevin type vibrator has been shown. However, any generator that generates ultrasonic vibration can be used, and the oscillation frequency from the oscillator can be changed. By controlling the size of the collected droplets, it is possible to control the size of the collected droplets, and further, a cleaning device that generates mist, a drying device, a food manufacturing device, a semiconductor wet processing device, a liquid crystal wet processing device, a precision cleaning device, etc. It can be installed in to collect harmful and harmless mist.
