A high-efficiency catalytic oxidation method for pretreatment of powdered activated carbon regeneration furnace

Abstract

The invention provides a powdered activated carbon regeneration furnace for preprocessing by an efficient catalytic oxidation method. The powdered activated carbon regeneration furnace comprises a base, a furnace body, a catalytic device, a feeding inlet, a burner, a separation plate, a spiral conveyer, a conveying motor, a destructive distillation cavity, an activation cavity, a sprayer, a spraying pipe, a water tank, a storing cavity, a discharging outlet and an exhaust pipe. The furnace body is fixed on the base and is successively divided to the catalytic device, the destructive distillation cavity, the activation cavity and the storing cavity by the separation plate from top to bottom. The feeding inlet is installed above the catalytic device. The discharging outlet is installed at the lower part of the storing cavity. Through the installation of the catalytic device, the powdered activated carbon regeneration furnace is capable of conveniently performing the catalytic oxidation treatment before the recovered activated carbon regeneration, reducing the adsorptive property of impurities adsorbed in the activated carbon, and improving the regeneration effect and efficiency. A solid-liquid separator, a recovering pipe and a recovering box are installed to recover and reuse catalysts. The actual use effect is better, and the powdered activated carbon regeneration furnace is convenient for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of industrial equipment, and in particular relates to a powdered activated carbon regeneration furnace for pretreatment by a high-efficiency catalytic oxidation method. Background technique [0002] Powdered activated carbon (Activated Carbon, AC) is a kind of adsorption material with very developed pore structure, large specific surface area, non-toxic and tasteless, and has a strong ability to adsorb molecules. , environmental protection and many other fields. In terms of environmental protection, activated carbon adsorption is widely used in the purification of polluted water sources and the advanced treatment of urban sewage and industrial wastewater, and is one of the important means of treating organic wastewater. [0003] The production cost of powdered activated carbon is high, and the waste of saturated activated carbon not only causes waste of resources, but also causes secondary environmental pol...
