It may be configured to include any one or more of the first and second inclined surfaces 634 and 636 so that, when only one of the first and second inclined surfaces 634 and 636 is formed, the hot air supplied from the combustion unit 500 moves in the upper or lower direction so that the low temperature By allowing air and hot air to generate a vortex, the effect of more smoothly mixing is realized.
  • the hot air from the combustion unit 500 moves upward and then moves in one direction again, so that the low-temperature air supplied in the other direction and By generating more and more eddy currents by the hot air, the effect of mixing the low temperature air with the hot air is realized more easily.

It is desirable to allow the concentrated harmful components to be evenly desorbed. If the low-temperature air and hot air are not smoothly mixed, the air having desorption heat is supplied only to a part of the desorption unit 210, so that the desorption of harmful components is performed smoothly. If not, the processing efficiency may be lowered.

Abstract

La présente invention concerne un système de purification de la pollution de l'air incorporé dans un boîtier, et plus particulièrement se rapporte à un domaine technique lié à un système de purification de la pollution de l'air incorporé dans un boîtier avec lequel des substances malodorantes et des composés organiques volatils générés dans une pièce peuvent être éliminés et évacués, et de l'air pur peut être fourni simultanément, et avec lequel non seulement l'efficacité de traitement est considérablement améliorée par la réutilisation d'une source de chaleur, mais les substances nocives concentrées dans une unité de désorption d'une unité de concentrateur peuvent être désorbées régulièrement, ce qui permet d'améliorer l'efficacité de purification.
