Scrubber with Ultrasonic Vapor Atomizer

The present invention relates to a scrubber for absorbing and removing various harmful substances such as fume hydrochloric acid (Fume) used in the industrial field, and in particular, the absorption of harmful substances by spraying the absorbent in the vapor state using ultrasonic waves to absorb the harmful substances. The present invention relates to a scrubber with an ultrasonic water vapor atomizer that can be maximized.

In general, the harmful substance absorbing device is intended to prevent air pollution by absorbing and removing harmful substances contained in the gas. Conventionally, a packing tower, a spray tower, a cyclo scrubber, a venturi scrubber, a jet scrubber, and the like are known. have.

1 (a) and 1 (b) are schematic diagrams showing a representative conventional scrubber device.

By spraying the absorbing liquid supplied along the supply pipe 6 through the nozzle 7 installed on the upper part of the main body 1, a gas containing harmful substances supplied from the gas pipe 2 rises from the lower part of the main body 1 Although it is configured to pass through the demister (8) and is absorbed by the absorbent liquid and discharged to the lower part, the harmful substances not absorbed are discharged through the upper gas outlet (3) to contaminate the atmospheric environment.

These scrubber devices use the basic principle of spraying the absorbing liquid into the gas to absorb and remove the harmful substances in the gas. However, the scrubber devices have different advantages and disadvantages, respectively. Since the absorbent liquid is sprayed into the liquid phase, there is a problem that the harmful effects of gas and the absorbent liquid are less contacted, so that the harmful substances cannot be removed smoothly, contaminating the air environment, and the power is consumed by spraying the absorbent liquid. There were many problems such as many.

The present invention is designed to solve the conventional problems as described above, by spraying the absorbent liquid in the state of water vapor, the effect of contact with harmful gas is large, the power cost is low, the water consumption is low, and the treatment of large amounts of harmful gas concentration An object of the present invention is to provide a scrubber with an ultrasonic water vapor spraying device capable of being used in parallel with an existing scrubber.

According to the present invention, a gas containing noxious substances supplied to the gas pipe 2 connected to one lower part of the main body 1 passes through a demister 8 in the center of the main body 1 and is installed in the supply pipe 6. In the scrubber configured to be discharged to the upper gas outlet (3) in contact with the sprayed liquid in the upper part, and absorbed harmful substances are discharged to the discharge pipe (9) in the lower part, the storage tank (11) installed inside the case (19) Spray tube for supplying the absorbent liquid to the absorbent liquid supply pipe 12 having the flow control valve 13 installed therein), and supplying the absorbent liquid in the state of water vapor with ultrasonic waves generated by the ultrasonic generator 14 installed at one lower side of the reservoir 11. An ultrasonic water vapor spraying device 10 is formed by installing 17 and the spray pipe 17 is connected to the gas pipe 2.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the scrubber with the present invention ultrasonic steam spray device.

2 is a schematic view showing a scrubber with an ultrasonic vapor spray device of the present invention, Figure 3 is a detailed view of the ultrasonic steam spray device of the present invention.

A storage tank 11 having a size adjustable according to a gas supply amount is installed in the case 19, and an absorbent liquid supply pipe 12 is installed, and a flow rate control connected to the level sensor 16 installed at one side of the storage tank 11 is provided. By installing the valve 13, the level of the absorbing liquid in the reservoir 11 is checked to maintain the level constantly at all times.

An ultrasonic generator 14 is installed at one lower side of the reservoir 11, a spray amount control switch 15 is installed at an outside of the reservoir 11, and is connected to a power switch 18 outside the case 19. do.

Next, the spray tube 17 is installed through the case 19 so that the absorbent liquid vaporized by the ultrasonic wave generated by the ultrasonic generator 14 is supplied, and the spray tube 17 is connected to the main body 1 of the scrubber. Connect to the gas pipe (2) which supplies gas to the bottom.

The ultrasonic water vapor spraying device 10 configured as described above may be used in parallel with a conventional scrubber, or may be used separately.

Hereinafter, the operation of the scrubber with the present invention ultrasonic steam spray device configured as described above will be described in detail.

Ultrasonic waves generated by the ultrasonic generator 14 installed inside the reservoir 11 strongly strikes the water molecules, vaporizes the water molecules, and the steamed fine particles are gas pipes 2 through the spray tube 17. And the gas pipe 1 is connected to the lower part of the body 1 of the scrubber.

Hazardous substances supplied from the gas pipe (2) is absorbed and removed by reacting with the water vapor sprayed first in the gas pipe (2), and the faint absorbent liquid is supplied to the inside of the scrubber body (1) to the demister (8) Passing through, several water molecules combine to be collected into water droplets and flow down.

If the pollution concentration of the gas is severe, it is possible to maximize the removal efficiency of harmful substances by spraying the absorption liquid from the nozzle (7) installed in the conventional scrubber in parallel treatment.

The spray amount control switch 15 is installed outside the reservoir 11 to adjust the spray amount according to the gas concentration.

As described above, when the scrubber with the present invention ultrasonic vapor atomizer is attached, the absorption liquid is sprayed in the vapor state to increase the contact efficiency with the gas containing harmful substances, thereby improving the removal efficiency of the harmful substances. In addition, it has a low energy cost and can be used efficiently even when the concentration of harmful substances is high.
