Abstract

The invention discloses a ceramic fiber catalytic filter tube with a function of catalytically oxidizing organic pollutants and a dust remover. The ceramic fiber catalytic filter tube comprises a ceramic fiber tube, a catalyst coating and a honeycomb carrier; wherein the ceramic fiber pipe is of a pipe body structure with an opening in the top; the top opening of the ceramic fiber tube is filled with the honeycomb carrier; and the catalyst coating is coated on the inner wall of the ceramic fiber tube and the honeycomb carrier. The main components of the ceramic fiber tube are Al2O3, SiO2 and TiO2, and TiO2 is added, so that organic pollutants in tail gas can be adsorbed; wherein the ceramic fiber tube and the V2O5 carrier are coated with the catalyst coatings respectively, organic pollutants in tail gas can be effectively catalyzed and oxidized to generate harmless gas CO2, H2O and the like, and therefore the requirements of emission regulations are met.

Description

technical field [0001] The invention relates to a ceramic fiber catalytic filter tube and a dust remover equipped with catalytic oxidation of organic pollutants, belonging to the intersecting field of catalyst preparation and dust removal material preparation. Background technique [0002] With the application and promotion of soil thermal desorption technology, polluted soil is indirectly heated by high-temperature flue gas in the thermal desorption reactor, and the moisture and organic matter in the soil volatilize into gaseous state after being heated, thereby separating from the solid soil, and this part of the gas is It is called "thermal desorption gas". Its main components are superheated steam and organic matter vapor, and it carries a large amount of dust. It has the characteristics of high temperature, high dust, high humidity, and high concentration of organic matter. [0003] Existing thermal desorption equipment usually adopts the thermal desorption gas treatmen...
