A hydrogen combustion steam activation furnace

Abstract

The invention provides a hydrogen burning water vapor activation furnace. The activation furnace is formed by a material activation reaction section, a gas buffer distribution section and a gas mixed burning section, wherein a feeding hole and an exhaust emission pipe are formed in the material activation reaction section; a material supporting gas distribution plate and a discharge pipe upper baffle are arranged at the bottom of the material activation reaction section and the bottom is communicated with a discharge pipe; the gas buffer distribution section is arranged below the material supporting gas distribution plate and the discharge pipe; a secondary gas distribution plate is arranged at the bottom of the gas buffer distribution section; the gas mixed burning section is formed by the secondary gas distribution plate and a primary gas distribution plate; a nitrogen inlet pipe is communicated in the gas mixed burning section; a hydrogen and oxygen mixer is arranged below the primary gas distribution plate and is communicated with an oxygen inlet pipe and a hydrogen inlet pipe. The activation furnace has the beneficial effects that the water vapor is controlled by inlet oxygen to activate materials via the distribution plates, thus utilizing the heat energy and saving the energy; besides, the materials are activated uniformly, thus improving the activation efficiency.

Description

technical field [0001] The invention relates to a method for physical activation of activated carbon and activation equipment for activated carbon, in particular to a method for activating activated carbon by burning steam with hydrogen and an activation furnace for burning steam with hydrogen. [0002] technical background [0003] Activated carbon is an excellent adsorbent. Because of its extremely developed inner pore structure and large specific surface area, it is widely used in various aspects such as chemical wastewater treatment and environmental protection. There are two production methods of activated carbon, chemical activation and physical activation. [0004] There are usually two kinds of activation furnaces in the existing physical activation methods, one is a vertical activation furnace, and the other is a horizontal rotary activation furnace. The vertical activation furnace is mainly the Sleep furnace, and its main disadvantages are: complex structure, high ...

AI Technical Summary

Problems solved by technology

Vertical activation furnaces are mainly Sleep furnaces, and their main disadvantages are: complex structure, high requirements for feed materials, and high technical requirements

During the actual operation of the activation furnace, the actual consumption of water fed into the activation furnace in the two processes of gasification and activation is unknown, and the actual consumption of water vapor in the activation process can only be calculated according to a specific calculation formula Conversion, there are inaccurate factors

Secondly, the phenomenon of uneven activation effect is easy to appear during the activation process.
