Description

  The present invention ultrasonically vibrates a metal pipe, generates a standing wave in the metal pipe, collects and collects particles in the gas, and removes mist from the sucked gas with a wire demister. It relates to a collection device.

  In general, as a particle recovery device, an evaporator is cooled and condensed, or dehumidification is performed using a cyclone or heating.

However, a system using such an evaporator or cyclone requires a very large device, and the oil mist recovery device uses a ceramic filter, a hepa filter, or a water flow film. Such a device also has a problem that it has a complicated configuration.

  The problem to be solved is that the conventional particle recovery apparatus becomes large, expensive, and complicated.

  The intake device is rotated by a motor, the mist collector introduces gas sucked by the intake device, collects the mist with a wire demister, the metal pipe is connected to the mist collector, and the ultrasonic transducer It is attached to a metal pipe, the mist collection bottle is connected to the mist collection device, collects the mist from the gas introduced by the air intake device with the wire demister of the mist collection device, and passes through the mist collection device to the metal pipe The particles contained in the introduced gas are attached and recovered by vibrating the pipe by the ultrasonic vibration of the ultrasonic vibrator.

  In the present invention, the mist is recovered from the gas introduced by the air intake device with the wire demister of the mist collecting device, and the metal pipe is ultrasonically vibrated by attaching an ultrasonic vibrator to the metal pipe. The particles are attached to the metal pipe from the introduced gas to recover the particles contained in the gas, and a complicated configuration is not required, so that maintenance is easy.

  FIG. 1 is a schematic configuration diagram of an ultrasonic particle collecting apparatus according to an embodiment of the present invention. FIG. 2 is a side sectional view of the mist collecting apparatus of FIG. 1, and a metal pipe 1 bent in a case is attached. An upper opening 3a of a mist collecting device 3 provided with a wire demister 2 is attached to a lower release portion of the metal pipe 1, and an intake device 5 for rotating and sucking air by a motor 4 is connected to a mist intake port 3b of the mist collecting device 3. The mist collection bottle 6 is attached to the lower opening 3 c of the mist collecting device 3, the upper part of the metal pipe 1 is released, and a bolted Langevin type ultrasonic vibrator 7 is attached to a part of the metal pipe 2. It is installed.

  In the ultrasonic particle collecting apparatus of the present embodiment configured as described above, when the intake device 5 is rotated by the rotation of the motor 4, ambient air is sucked from the intake device 5 into the mist collecting device 3, and the wire demister 2 Mist contained in the air is collected, and the air that has passed through the mist collecting device 3 is introduced into the metal pipe 1. When the ultrasonic vibrator 7 vibrates, the air that passes through the metal pipe 1 is collected. Comes into contact with the inner wall of the metal pipe 1, moisture particles adhere to the inner wall of the metal pipe 1, flow downward as water droplets, and are collected from the mist collecting device 3 through the wire demister 2 in the mist collecting bottle 6. The

  In the ultrasonic particle collecting apparatus of the present embodiment configured as described above, the wire demister 2 of the mist collecting apparatus 3 removes the metal pipe 1 from the air sucked by the intake apparatus 5 and the ultrasonic vibrator 7 can remove moisture in the air with a simple configuration that only vibrates.

  In addition, although the example which removes the moisture contained in gas was demonstrated in the said Example, you may make it remove oil particles from oil mist, and may remove substances, such as a tar, from tobacco smoke. In addition, substances contained in the smoke may be removed from the flue gas in the factory.

It is a see-through | perspective perspective view of the ultrasonic particle collection apparatus of the Example of this invention. It is an expanded side sectional view of the mist collection device of the ultrasonic particle collection device of FIG.
