In other words, in special workplaces such as dairy processing companies, wastewater treatment plants, and excreta treatment plants, harmful components including bacteria are intensively generated along with bad odors. It can only be removed, but sufficient deodorization and sterilization functions are not provided.

In addition, since the conventional air purifier simply uses a filtration method by a filter or an adsorption removal method by an adsorbent, there is a limit in its adsorption performance and the filter must be cleaned or replaced frequently, which causes inconvenience and increases the maintenance cost. There was a problem.

Furthermore, although wet cleaning is used to intensively treat odors, it requires a large installation area, increases maintenance costs according to the use of treatment agents, and removes secondary pollutants such as wastewater and waste sludge. There were problems such as generating.

In view of the above circumstances, at this point in time, there is a need for an air purification treatment device that can completely detoxify polluted air containing high concentrations of odors and harmful components, while also enabling economical operation.

In addition, when a method of purifying air by a burning method is adopted, foreign substances and oils contained in the air are deposited while burning on the surface of the filter generating a high temperature, thereby reducing the purification efficiency.

In addition, in order to wash the filter applied to the air purification method of the burning method, there is a problem in that it takes a lot of time due to the operation stop where the purification cannot proceed because the method through disassembly must be used.

Since the purification process has been described above, a repeated description thereof will be omitted.

Here, in the third purifying unit 400 that maintains the standby state, the third circulation valve 472 , the third intake valve 404 , and the third exhaust valve 406 are all closed.

In this case, a first differential pressure sensor unit and a second differential pressure sensor unit may be disposed above the first catalytic filter 230 and the second catalytic filter 330 , that is, at the outlet end 260 , and the first and second differential pressures The sensor unit may sense the pressure of the air passing through the first catalytic filter 230 and the second catalytic filter 330 and transmit it to the control unit.

When the pressure value transmitted from the first and second differential pressure sensor units is equal to or greater than the set value, the control unit determines that the filtering efficiencies of the first catalytic filter 230 and the second catalytic filter 330 are normal and continues to the first purifier ( 200) and the second purification unit 300 may perform a purification process.

On the other hand, when the pressure value transmitted from the first and second differential pressure sensor units is equal to or less than the set value, the control unit determines that the filtering efficiency of the first catalytic filter 230 and the second catalytic filter 330 is abnormal, and thus the first purifying unit ( 200 ), the second purifying unit 300 may perform a regeneration process, and may operate the third purifying unit 400 to perform a purifying function.

When the second purifier 300 and the third purifier 400 perform the purification function and the first purifier 200 performs the regeneration function, the first heatable filter of the first purifier 200 220 is turned off, the first intake valve 204 and the first exhaust valve 206 are closed, and at the same time, the first circulation valve 272 is opened and the first circulation fan 274 is operated. .

When the respective valves are opened and closed in this way, the first heaterable filter 220 is turned on again by an electrical signal to increase the temperature. will be done

Accordingly, as the air in the first purifier 200 circulates in the reverse direction opposite to the purifying process, suspended substances such as fine dust adhering to the first catalytic filters 230 fall while the first heatable It is carbonized by the filter 220 so as to be extinguished, so that regeneration is achieved.

At this time, after the regeneration time of the first purifier 200 is set to about 30 to 500 minutes, the first circulation valve 272 is closed, and the operation of the first circulation fan 274 is stopped. , by turning off the first heatable filter 220 and then switching to the standby mode.

In this state, when the filtering efficiency of the second purifying unit 300 and the second catalytic filter 330 is lowered, the second purifying unit 300 switches the regeneration process and the first purifying unit ( 200) is converted back to the purification process, and the conversion to the regeneration process of the second purification unit 300 and the purification process of the first purification unit 200 is the same as the regeneration process of the first purification unit 200 described above.
