High-efficiency desulfurized active coke analysis tower and analysis method

Abstract

The invention discloses a high-efficiency desulfurized active coke analysis tower and an analysis method. The analysis tower comprises a material feeding section, a preheating section, a first buffering section, an analysis section, a second buffering section, a cooling section and a material discharging section which are communicated with one another in sequence from top to bottom, wherein the preheating section, the analysis section and the cooling section are all of tube-shell type heat exchange structures; a cooling section gas inlet is formed in the lower part of the cooling section, and a cooling section gas outlet is formed in the upper part of the cooling section and is communicated with an analysis section gas inlet formed in the lower part of the analysis section; an analysis section gas outlet formed in the upper part of the analysis section is communicated with a preheating section gas inlet formed in the lower part of the preheating section; a preheating section gas outlet formed in the upper part of the preheating section is emptied; the first buffering section is provided with a material distribution and gas guide structure and an analysis gas outlet; the analysis gas outlet is connected with an acid preparation system through a fan. The invention also provides an analysis method of the analysis tower. The analysis tower is simple in structure, high in heat exchange efficiency and low in energy consumption; regeneration of desulfurized active coke is realized; furthermore, high-concentration SO2 can be obtained, and recycling of sulfur is realized.

Description

technical field [0001] The invention relates to the technical field of active coke flue gas purification, in particular to a high-efficiency desulfurization active coke analysis tower and analysis method. Background technique [0002] In recent years, my country's environmental problems have become increasingly prominent, especially air pollution dominated by "smog weather", which seriously endangers people's health. Coal-fired power plants are the main pollution source of the atmospheric environment, and have been the focus of environmental governance for many years. In response to the national call, most domestic power plants are equipped with SCR, ESP, FGD and other technologies to control NOx, dust, SO 2 The emission of pollutants, etc., has achieved good results. However, there are many problems in the existing technology, such as long process chain, high energy consumption, low removal efficiency, and secondary pollution. Therefore, my country urgently needs to deve...

Problems solved by technology

[0006] The analytical tower is the core equipment of the activated coke flue gas desulfurization process, but the application of this process in my country is just in its infancy, especially the power plant scale application has no performance in my country, so my country urgently needs to develop a high-efficiency analytical tower with independent intellectual property rights, Reduce analytical energy consumption and lay the foundation for the promotion of this process
