Problems solved by technology

When regenerating corrosive granular waste carbon, it is necessary to consider that corrosive high-temperature exhaust gas will be generated during the carbonization and activation process of corrosive granular waste carbon. These high-temperature exhaust gases will corrode equipment. Usually, the regeneration of activa

Embodiment Construction

[0033] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0034] Such as figure 1 As shown, the corrosive granular waste carbon regeneration method of the present invention is: firstly dry the corrosive granular waste carbon, and then use the carbon activation integrated rotary kiln to carbonize and activate the corrosive granular waste carbon, thereby obtaining the regenerated activated carbon product ;The high-temperature tail gas produced by the carbon activation integrated rotary kiln is collected and dried by a corrosion-resistant tail gas collection tower, and then the high-temperature tail gas is sent to the secondary combustion chamber for combustion treatment. Neutralization treatment, dioxin absorption treatment, dust removal treatment and lye spray treatment for harmless treatment of h...

Abstract

The invention relates to a corrosive granular waste carbon regeneration method which is as follows: first drying corrosive granular waste carbon, and then carbonizing and activating the corrosive granular waste carbon by using a carbon activating integrated rotary kiln to obtain a regenerated activated carbon product; using a corrosion-resistant exhaust gas collection tower for collecting and drying high-temperature exhaust gas generated by the carbon activating integrated rotary kiln, sending the high-temperature exhaust gas into a second combustion chamber for combustion treatment, and sequentially performing heat recovery, neutralization treatment, dioxin absorption treatment, dust removal treatment and lye spray treatment on the combusted high-temperature exhaust gas to facilitate theharmless treatment of the high temperature exhaust gas. The method is a set of scheme mainly designed for regenerative production of the corrosive granular waste carbon, and the method comprises the regenerative processing of the corrosive granular waste carbon and the harmless tail gas treatment, the process flow is configured reasonably, and energy in the process flow is efficiently used, production efficiency is high, and the method helps an enterprise to improve the capacity of regeneration of the corrosive granular waste carbon.

Description

technical field [0001] The invention relates to the technical field of active carbon regeneration, in particular to a method for regenerating corrosive granular waste carbon. Background technique [0002] After the adsorption of activated carbon is saturated, the renewable granular carbon accounts for about 70%. Regeneration treatment not only satisfies the recycling of resources, reduces resource consumption, but also saves a lot of costs for enterprises. [0003] At present, there are many regeneration methods for activated carbon, such as: heating regeneration method, biological regeneration method, wet oxidation method, solvent regeneration method, electrochemical regeneration method, catalytic wet oxidation method, etc. The heating regeneration method is the most widely used and industrially mature activated carbon regeneration method. [0004] The regeneration of activated carbon requires corresponding regeneration treatment according to the properties of waste carbon...
