That is, the pressure sensor described above is installed between the inlet hood 20 and the inlet damper 30 to check the pressure on the side into which the contaminated air flows, and is installed between the steam injection port and the filter 40 to be purified. The pressure difference between the intake damper 30 and the outtake damper 60 is determined by checking the pressure of the purified air installed between the intake damper 60 and the outflow hood 70. At the same time controlling the operation, it is possible to automatically monitor the failure of the multi-chamber 14 type mist separator.

Hereinafter, the overall operation of the multi-chamber type mist separator 1 according to an embodiment of the present invention will be described.

First, air containing contaminants such as oil mist and dust generated in various industrial processing processes is introduced through the inlet hood 20, in which the inlet damper 30 and the outlet damper 60 are introduced. Are all open.

The contaminated air introduced into the inlet hood 20 is separated into each chamber 14 through the grid 22 of the inlet hood 20, and then enters the inlet damper 30 and the outlet damper 60. ) Rotates in turn to seal the chamber 14.

Then, steam is injected from the steam injection port and the auxiliary steam injection port to remove contaminants such as oil mist and dust adhered to the filter 40 and the auxiliary filter 80. Sediment and waste water generated in the discharge through the discharge pipe 110 to the tank 100 outside.

The air purified while passing through the two filters 40 is discharged to the outside through the withdrawal hood 70 while the withdrawal damper 60 is opened, and then the intake damper 30 is also opened to introduce contaminated air again. .

This series of processes, though not shown, are automatically controlled through a controller (not shown) installed on the body 10.

That is, a pressure sensor is installed between the inlet hood 20 and the inlet damper 30 to check the pressure on the side into which the contaminated air flows, and the pressure on the side that is installed and purified between the steam injection port and the filter 40. The pressure of the purified air is installed between the withdrawal damper 60 and the withdrawal hood 70.

Then, the controller determines the detected pressure for each section to block or open the inlet damper 30 and the outlet damper 60 to continuously purify the contaminated air, or to select a specific one of the plurality of chambers 14. When the chamber 14 is abnormal due to clogging of the filter 40 due to contaminants, the inlet damper 30 and the outlet damper 60 are blocked to stop the purification of the specific chamber 14. .

At this time, in the case of the multi-chamber type mist separation apparatus 1 according to the present invention, as compared with the conventional mist separation apparatus formed of one chamber 14, the abnormality is generated as it consists of a plurality of independent chambers 14. Even if the purification operation of the specific chamber 14 is stopped, it is not necessary to stop the operation of the entire facility, and the local replacement and maintenance of the specific chamber 14 in which an abnormality occurs while operating the facility can be performed.

As described above, the multi-chamber type mist separator according to the present invention collects, separates, and purifies pollutants such as oil mist and dust generated in various industrial processing processes through separate chambers. As a result, it is possible to prevent the entire operation of the facility for the clogging of the filter and the maintenance thereof, thereby having an excellent effect of minimizing productivity disruption and human physical loss.

In addition, by sensing the pressure of the chamber through the pressure sensor installed inside the chamber it is possible to control each chamber in sequence, there is an advantage that can be operated effectively unmanned operation.
