A predetermined amount is controlled to be introduced into the water tank 200 through the solution supply pipe 122, and when the temperature of the washing water detected by the temperature sensor 220 is less than or equal to the preset set temperature t1, the washing water temperature is The heater 240 is driven until the set temperature t2 is equal to or higher than the set temperature t2, and the washing water is heated. When the level of the washing water detected by the water level sensor 230 is lower than the preset level, a warning is displayed. To control.

4 and 6, in more detail, the pH value of the washing water is lowered as the system driving time elapses, so that the pH value of the washing water detected by the pH sensor 210 is preset in the controller 410. When the pH is lower than or equal to the set pH, the controller 410 opens the solenoid valve 123 in the closed state to maintain the proper pH of the washing water, thereby removing the sodium hydroxide solution stored in the solution container 121 from the solution supply pipe 122. Through a predetermined amount to the tank 200 through.

In addition, when the ambient temperature of the system decreases and the temperature of the washing water detected by the temperature sensor 220 reaches or falls below a preset temperature t1 preset by the controller 410, the controller 410 operates the heater 240. Thus, the temperature of the washing water is maintained at or above the preset temperature t2 preset by the controller 410. Here, the set temperature t2 is higher than the set temperature t1.

In addition, when the water level of the washing water stored in the water tank 200 decreases as time elapses, and the level of the washing water detected by the water level sensor 230 reaches a level lower than or equal to the preset water level preset by the controller 410. The control unit 410 displays a warning to the outside through the operation of a warning sound or a warning light. Here, the known technology may be adopted as the warning display technology by the operation of the warning sound or the warning lamp.

In one embodiment of the present invention, the intake and exhaust unit 300 is connected to the control unit 410 of the controller 400 on one side of the exhaust port 320 to measure the amount of harmful gas present in the purified air discharged. An exhaust sensor 330 is further provided.

That is, the exhaust sensor 330 is a harmful gas such as sulfur dioxide (SO ₂ ), nitrogen dioxide (NO ₂ ), carbon monoxide (CO), hydrogen sulfide (H ₂ S), etc., which may exist in the purified air discharged from the exhaust port 320. And measure the amount of fine dust (PM ₁₀ ) or ultra-fine dust (PM _2.5 ) and transmits to the control unit 410. Based on the information transmitted from the exhaust sensor 330, the control unit 410 generates harmful gas information D1 including information on the amount of harmful gas and fine dust PM ₁₀ or ultrafine dust PM _2.5 . The harmful gas information D1 is transmitted to the wireless communication unit 420.

Subsequently, the wireless communication unit 420 transmits the smartphone S through the wireless communication of the noxious gas information D1. As a wireless communication technology, a known wireless communication technology using WiFi or Bluetooth may be adopted, and the harmful gas information D1 transmitted from the wireless communication unit 420 may be a system control application for controlling the system of the present invention. ) Can be received from the smartphone (S) running and running.

Therefore, the user of the system of the present invention can check the purified air state together with the harmful gas information (D1) in real time through the smartphone (S). As a result, the system user can easily determine whether to continue to drive the system or how long to drive the system in consideration of the air purification state or to stop the driving of the pump 600.

In addition, when the system user transmits the pump driving information (D2) from the smart phone (S) by generating the pump driving information (D2) about the driving time of the pump 600, the ON / OFF driving of the pump through the application The wireless communication unit 420 may receive the pump driving information D2 through wireless communication.

When the wireless communication unit 420 receives the pump driving information D2, the wireless communication unit 420 transmits the information D2 to the control unit 410, and the control unit 410 transmits the pump 600 according to the pump driving information D2. ) Can be controlled.

For example, the user of the system through the application of the smartphone (S), the driving time information of the pump 600, the pump driving information (D2) or the ON driving information of the pump 600 or the OFF driving information of the pump 600 The controller 410 may drive the pump 600 for a predetermined time, drive the pump 600 ON, or drive the pump 600 OFF based on the transmitted information.

On the other hand, as an embodiment, the controller 410 may analyze the harmful gas information (D1) to automatically stop the operation of the system when the amount of harmful gas and fine dust is less than the reference value.

In a preferred embodiment of the present invention, the control unit 410 is to operate the pump 600 so that the water film layer (W1) of a predetermined height is first formed on the perforated plate 110 at the beginning of the operation of the dust collecting and air purification system. After driving first, the blower 310 is driven after a predetermined time and the on / off valve 530 is opened.

This will be described in more detail with reference to FIGS. 2, 3D, 4, 6, and the like. If the pump 600 and the blower 310 are driven at the same time, harmful air is introduced into the scrubber part 100 to be discharged to the exhaust port 320 before the water film layer W1 is formed on the perforated plate 110. Since the pump 600 is driven first, the washing water is first discharged from the washing water discharge unit 130, so that the water film layer W1 having a predetermined height is first generated on the perforated plate 110 before harmful air is introduced. There is.

Therefore, the controller 410 of the present invention drives the pump 600 first when the system starts to drive, and discharges the washing water first from the washing water discharge unit 130 so that only the washing water falls in the scrubber unit 100 for a predetermined time. . During this time the blower 310 is not driven and the on / off valve 530 is also in a closed state. After the initial predetermined time elapses, when the water film layer W1 having a predetermined height is generated on the perforated plate 110, the controller 410 drives the blower 310 to allow harmful air to flow into the scrubber part 100 and to open and close the same. The valve 530 is opened to supply the compressed air and the washing water to the washing water spray nozzle 170, and the washing water spray layer F is formed on the perforated plate 110 by the washing water spray nozzle 170 as described above. To be created.

As a result, the harmful air flowing into the scrubber part 100 can be reliably collected and purged without harmful air being discharged as it is without being purified at the beginning of system operation.

While the embodiments of the present invention have been described above, it will be apparent to those skilled in the art that various modifications can be made without departing from the scope of the technical idea.
