Abstract

The invention discloses a device for removing dioxin in furnace slag. The device comprises a slag crusher and a photocatalytic reactor, wherein the slag crusher comprises a slag crushing chamber; an upper rotary blade group and a lower rotary blade group are sequentially arranged in the slag crushing chamber from top to bottom, and are mutually staggered along the horizontal direction; the photocatalytic reactor comprises a reaction chamber, a spiral material conveying device is arranged at the bottom part of the interior of the reaction chamber in an inclined downward way, an ultraviolet lamp is arranged at the top part of the reaction chamber, and a photocatalyst coating is arranged at the side wall of the reaction chamber; the bottom part of the slag crushing chamber is connected with a material inlet of the spiral material conveying device, and the tail part of the spiral material conveying device is provided with a material outlet which is communicated with the exterior of the reaction chamber. The device is used for effectively removing the dioxin substances in the furnace slag.

Description

technical field [0001] The invention relates to the field of solid waste treatment, in particular to a device for removing dioxin in furnace slag. Background technique [0002] At present, a large amount of slag is produced in boiler equipment such as coal-fired boilers. The treatment of slag usually adopts processes such as water washing and transportation to remove the dust in the slag. But even after dust removal, many workers in slag recycling still experience frequent physical discomfort, the cause of which has never been discovered. During an accidental investigation, the applicant found that many dioxin-like substances were mixed in the slag, and dioxin-like substances would have many harmful effects on the immune system and metabolic system of the human body. Because dioxins often exist in the gaseous phase and will be mixed in the solid slag, they have not been found. In view of this, the applicant provides a device for removing dioxins in slag, thereby obtaining...
