Embodiment approach

[0036] In this embodiment, ensure that the material conveying capacity of the auxiliary discharge screw conveying mechanism 50 is less than or equal to the material conveying capacity of the discharge screw 40, so that the material conveying capacity of the auxiliary discharge screw conveying mechanism 50 will not be too large As a result, the discharge screw 40 cannot deliver the auxiliary discharge screw mechanism 50 to the material near the dust removal material outlet 15 in time, resulting in material accumulation. Of course, it can be understood that, preferably, v1 / v2 is equal to V1 / V2, and at this time, the material conveying capacity of the auxiliary discharge screw conveying mechanism 50 matches the material conveying capacity of the discharge screw 40, reducing material accumulation. At the same time, the discharge screw 40 can output the material with the maximum conveying capacity.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a particle bed dedusting device. Background technique [0002] Coal pyrolysis gas contains a large amount of dust and tar. If the tar and dust are not removed from the coal pyrolysis gas in time, once the temperature drops, the dust and the condensed tar will stick together, which may cause the pyrolysis system to be forced to shut down. If the dust in the pyrolysis gas is not sufficiently removed, the dust will contaminate or block subsequent coal tar processing equipment, reducing the quality of coal tar. [0003] Existing devices for dedusting coal pyrolysis gas are mainly granular bed dedusting devices. Most of the existing granule bed dedusting devices include a main body. The material inlet and the dust removal material outlet, the granular material for dust removal enters the inner cavity from the dust removal material inlet and falls into the bed cavity, a discharge sc...
