  • the steam spraying means 30 is configured on the hot air inlet 12 side of the scrubber housing 10 and the steam is sprayed in a direction opposite to the inflow direction of the hot air, so that the steam particles are moved by the hot air, and the scrubber housing (10) Through the diffusion to the inside, the fine dust particles of the hot air can be absorbed and removed after sufficient contact with the steam inside the scrubber housing 10.
  • the white smoke removal means 100 is configured on the side of the hot air outlet 13 of the scrubber housing 10, and the hot air is condensed or condensed to remove the precipitation so that white smoke is not generated by the hot air exhausted to the outside.
  • the present invention shows that the scrubber housing 10 is configured at the rear end of an industrial facility such as a power generation facility or an incineration facility, but the configuration of the present invention is contaminant or fine particles in a closed space other than a power generation facility or an incineration facility. It is desirable to apply it to the space of all industrial facilities where air containing dust is generated so that fine dust can be removed.

Abstract

Un dispositif d'élimination de poussière fine et de fumée blanche de type épurateur est fourni selon la présente invention. Le dispositif comprenant : un carter d'épurateur qui a une structure cylindrique et fournit un espace pour éliminer des matières polluantes et de la poussière fine tandis que le vent chaud comprenant les matières polluantes et la poussière fine s'écoule dans une installation industrielle et est évacué de celle-ci ; un moyen de pulvérisation d'eau qui est installé sur la partie supérieure de l'intérieur du carter d'épurateur et pulvérise de l'eau vers la partie inférieure de façon à adsorber et à éliminer les particules d'odeurs ou les particules polluantes ; et un moyen de pulvérisation de vapeur qui est installé sur la partie inférieure de l'intérieur du carter d'épurateur et pulvérise de la vapeur dans la direction opposée du vent chaud vers une entrée de vent chaud conçue au niveau de la partie inférieure du carter d'épurateur, ce qui permet à des particules de vapeur d'être déplacées au moyen du vent chaud et ensuite d'être diffusées à l'intérieur du boîtier d'épurateur, et permet aux particules de poussière fines d'être adsorbées et éliminées après avoir été en contact avec les particules de vapeur à l'intérieur du carter d'épurateur.
