Problems solved by technology

[0003] On the other hand, the so-called super activated carbon with high specific surface area and microporous structure is an important new material in the field of clean energy. It has the performance of large-capacity storage of natural gas and hydrogen, and has special adsorption and separation performance. The product of the source of goods, because the preparation of this kind of activated carbon involves environmental protection and energy consumption issues
Prepared by chemical activation method, the cost is too high due to environmental protection requirements
Prepared by physical activation method, due to the low reaction rate and long time, the energy consumption is too high

Embodiment Construction

[0008] According to the size of the waste incinerator and the size of the suitable temperature zone, the length and diameter of the activation furnace are designed. One end of the furnace body is provided with an activated carbon raw material inlet and an oxidant (incinerator tail gas) inlet, and the other end is provided with an exhaust gas outlet and a pipeline connected to the incinerator fuel inlet, as well as an online detection and feedback control system for CO. This end is equipped with a finished charcoal unloading device. Depending on the activation temperature, the type and amount of catalyst, the activation time is 80-160 hours.

Abstract

The present invention provides the process of preparing active carbon with high surface activity in activating furnace coupled to a garbage incinerator. The main points of the process includes utilization of high temperature produced in garbage incinerator for activating, utilization of the tail gas of the garbage incinerator as the oxidant for activating, and returning the tail gas of the activating furnace to the garbage incinerator for re-burning. The present invention can reduce the preparation cost of active carbon with high surface activity and raise the total economic utility of garbage incinerator.

Description

technical field [0001] The invention relates to a new preparation method of high-surface activated carbon and a way to improve the economic benefits of garbage incinerators, belonging to the preparation of high-surface activated carbon and garbage incineration technology. Background technique [0002] The harmless disposal of urban waste is an important topic that has attracted worldwide attention. my country's cities are growing rapidly, and the problem of garbage disposal is an urgent task. The core technology for the harmless treatment of garbage is the incinerator. Improvements in incinerator design can reduce waste disposal costs, but the current economics of the best waste disposal technologies still make the harmless disposal of waste an important national burden. An effective way to solve this problem is to try to increase the added value of by-products in the waste incineration process. The direct product of the incinerator, whether it i...
