Referring to the first to fourth embodiments, the electrothermal desorption air treatment device 10 according to a preferred embodiment of the present invention comprises a housing 20, a substrate 32, an electrothermal layer 34, and a plurality of adsorbent materials 36. A temperature sensor 40 and a second protection net 42.

The housing 20 has a rectangular tubular shape and is hollow inside and has a first opening 22 and a second opening 24.

The substrate 32 is cylindrical and made of a ceramic material and has a front side 321 , a rear side 323 and a plurality of mutually parallel passages 325 which extend through the front side of the substrate 32.

The electrothermal layer 34 (as shown in the third figure) is formed of a material of a resistor and can generate thermal energy by energization, and is formed on the front side surface 321 of the substrate 32, the rear side surface 323, and the inner side wall surface of the channels 325. .

The adsorbent material 36 is a porous material of zeolite and is filled in the channel 325 of the substrate 32. The adsorbent material 36 has a gap 38 between the inner wall surface of the channel 32 and between the adsorbent material 36 and the adsorbent material 36. There is also a pore 39 for the gas to pass through; in the embodiment, the adsorbent material has a spherical shape, but may also be spherical, powder, strip or irregular, and further, the adsorbent 36 itself Pores can also be provided for airflow. In addition, in the present embodiment, the overall shape of the substrate 32 is cylindrical, but the designer can also design the substrate 32 into a square column, a columnar shape, or even a length, a width, and a height according to the shape of the pipe. For the equal rectangular parallelepiped, the cross-sectional shape of the passage 325 may be designed in any other shape, such as a circle, a square, a rectangle or a triangle, in addition to the regular hexagon shown in the fourth figure.

The temperature sensor 40 is accommodated in the channel 325 of the substrate 32 and can be monitored The internal temperature of the channel 325 is fed back to a heating controller (not shown).

The second mesh 42 (as shown in the third figure) is respectively disposed on the front side of the substrate 32 and is attached to the front side 321 and the rear side 323 to prevent the adsorbent material 36 from leaving the channel 325 by rolling.
