Vertical-type discharge active carbon regenerating furnace

Abstract

The invention discloses a vertical-type discharge active carbon regenerating furnace. The vertical-type discharge active carbon regenerating furnace comprises a stander, wherein the top end of the stander is provided with a feeding cabin, the bottom end of the stander is provided with a discharging cabin, a regenerating furnace group is arranged between the feeding cabin and the discharging cabin, the regenerating furnace group consists of a plurality of regenerating furnaces which are successively arranged from top to bottom, each regenerating furnace comprises an insulation sleeve, an annular graphite electrode and a central electrode, the central electrode is fixed at the center of the insulation sleeve, the annular graphite electrode is coaxially assembled in a cavity of the insulation sleeve, a conductive plate is embedded between the annular graphite electrode and the inner wall of the insulation sleeve, the outer wall of the central electrode is provided with threaded projections, the inner wall of the annular graphite electrode is correspondently provided with threaded projections, and an annular regenerating cavity is formed between the outer wall of the central electrode and the inner wall of the annular graphite electrode. By adopting an annular furnace body and the central electrode structure, the active carbon is uniformly heated; and by adopting a multi-sectional independent furnace body structure, the temperature requirement for the activation of the active carbon can be met.

Description

technical field [0001] The invention belongs to the field of chemical equipment, in particular to a vertical discharge activated carbon regeneration furnace. Background technique [0002] Activated carbon is a good material for water filtration and impurity removal. Activated carbon can be regenerated by activated carbon regeneration technology for repeated use after the adsorption is full. Activated carbon regeneration technology requires the use of discharge activated carbon regeneration furnace. The existing discharge activated carbon regeneration furnace is generally vertical. Its structure generally heats and regenerates the activated carbon through the discharge of two parallel flat electrodes located inside the vertical rectangular furnace body. Such a regeneration furnace will bring the following two problems: [0003] ①Because the furnace body is rectangular, the four corners inside the furnace body are dead corners. The activated carbon flows slowly in the dead cor...
