Description

technical field

[0001] The invention relates to a technical field of air pollution control, in particular to a regeneration device and a regeneration method for regenerating desulfurization activated carbon that has lost part or all of its activity. Background technique

[0002] At present, in order to solve the problems of environmental pollution caused by coal burning and lack of sulfur resources in my country, and to promote the establishment of a conservation-oriented society and sustainable economic development in China, activated carbon flue gas desulfurization technology has been vigorously developed in recent years. This technology uses activated carbon as a desulfurizer to absorb sulfur dioxide in flue gas and store it in the micropores of activated carbon in the form of hydrated sulfuric acid. With the progress of adsorption and reaction, the activity of activated carbon gradually decreases. In order to ensure the continuous desulfurization process, the activated c...

Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0048] It can be clearly seen from Fig. 1 that the moving bed desulfurization activated carbon regeneration method designed by the present invention is composed of the following equipment: air blower 1, air preheater 5, hot blast stove 6, regeneration equipment 7, inert gas blower 9, water pump 11, water tank 13 and regenerative gas extraction induced draft fan 16 to form. The air preheater 5 is a tube-and-tube heat exchanger, and the material can be Corten steel or NI steel with good acid dew point corrosion resistance. The outer wall of the heat exchange tube is welded with spiral fins to enhance heat exchange, and the heat exchange surface is painted for corrosion protection. According to the fuel form (solid, liquid or gas), select different hot blast stoves 6 for use. The regenerative gas extraction induced draft fan 16 is selected from a temperat...
