Problems solved by technology

traditional control SO 2 Emission methods mainly include wet flue gas desulfurization, rotary spray dry desulfurization, and furnace calcium spray desulfurization, etc. These methods have been successfully applied. For example, the commonly used desulfurization method is wet desulfurization, such as "Control method of gas wet method and desulfurization process" (patent No. 87102943) and "exhaust gas desulfurization method" (patent No. 87106325), etc., are wet

Embodiment Construction

[0024] Enumerate the embodiment of the present invention below:

[0025] Set up a thermal test bench in the laboratory, and refer to the accompanying drawings for the system. Simulated flue gas was used for desulfurization experiments, wherein the volume ratio of each component was: 6% oxygen, 5% water vapor, 2000ppm, 1500ppm and 1000ppm sulfur dioxide, and the rest was nitrogen. Flue gas components before and after desulfurization were measured by a flue gas analyzer (Master2000 Gas Analyzer) and chemical titration. The desulfurization reactor, regeneration reactor, and catalytic conversion tower all use electric heating tube furnaces to maintain a stable reaction temperature.

[0026] The desulfurizer of the present invention adopts the DS01 and DS02 desulfurizers proposed in the "Renewable Metal Oxide Desulfurizer and Its Preparation" patent that the applicant applied for at the same time. Adsorb a lot of SO 2 After the gas reaches saturation, it is transferred to the re...

Abstract

The present invention relates to regenerable metallic oxide sulfur removal technology and system, said system includes desulfurization part, regeneration part and by product treatment part. The desulfurizing agent is prepared by using regenerable metallic oxide active component as absorbent and assisted by catalyst, to remove SO2 in smoke in desulfurization reactor, the SO2 saturated desulfurizing agent is regenerated in regenerator to produce mixed gas containing high concentration SO2, SO3, which is then catalyzed, transferred and absorbed to obtain concentrated sulfuric acid by product with concentration higher than 92%. The sulfur removal efficiency can be higher than 88%, the sulfurizing agent can be cyclically reused, it is low in cost and has no secondary pollution.

Description

technical field [0001] The invention relates to a method for removing SO in flue gas 2 Gas renewable metal oxide desulfurization technology and system. Background technique [0002] SO contained in flue gas (gas) released by burning fossil fuels (coal, oil, natural gas, etc.) in energy, chemical, metallurgy, electronics and other industries 2 Cause serious pollution to the atmosphere, my country has become the world's largest SO 2 As the country with the largest emission and the third largest acid rain area, environmental issues have become a key issue for the sustainable development of my country's national economy. In recent years, the Chinese government has paid great attention to environmental issues. For example, my country's Environmental Protection Law has clearly stipulated that power plant boilers that burn coal with a sulfur content greater than 1% must be equipped with desulfurization facilities. [0003] In recent years, the practi...
