High-sulfur and high-halogen hazardous waste compatibility method

Abstract

The invention discloses a high-sulfur and high-halogen hazardous waste compatibility method. The method comprises the following steps of taking a part of hazardous waste materials as sample hazardouswaste, separating inorganic salts and ashes from the sample hazardous waste, and determining the mass ratio of sulfur, chlorine and / or fluorine in the separated inorganic salts and ashes through measurement; incinerating the sample hazardous waste remaining after separating the inorganic salts and ashes, absorbing flue gas generated by incineration through a solution, and detecting sulfur, chlorine or fluorine components in the solution so as to determine the mass ratio of organic sulfur and / or organic halogen in the sample hazardous waste; determining the type of the hazardous waste accordingto the mass ratio of the organic sulfur and / or organic halogen of the sample hazardous waste, specifically, the hazardous waste is high-halogen hazardous waste; and mixing the high-sulfur and high-halogen hazardous waste with non-high-sulfur and non-high-halogen hazardous waste to obtain new non-high-sulfur and non-high-halogen hazardous waste. According to the high-sulfur and high-halogen hazardous waste compatibility method, the content of pollutants generated by the high-sulfur and high-halogen hazardous waste in a furnace can be controlled, so that the long-term stable operation of a system is ensured.

Description

technical field [0001] The invention relates to the technical field of hazardous waste treatment, in particular to a high-sulfur and high-halogen hazardous waste compatibility method. Background technique [0002] In recent years, with the rapid development of the environmental protection industry, many companies are actively entering the field of hazardous waste disposal. At present, my country's hazardous waste is mainly disposed of by incineration technology. Under the current market background, hazardous waste incineration devices are only suitable for low-sulfur waste. Low-halogen incineration and the compatibility of hazardous waste entering the furnace mainly rely on the detection of the calorific value, flash point, phosphorus, total sulfur, and total chlorine of hazardous waste for routine compatibility. It cannot detect and distinguish high-sulfur, high-halogen hazardous waste from ordinary hazardous waste, nor distinguish between halogen and inorganic salts, and do...

AI Technical Summary

Problems solved by technology

It cannot detect and distinguish high-sulfur, high-halogen hazardous waste from ordinary hazardous waste, nor distinguish between halogen and inorganic salts, and does not separately detect copper, which has a greater impact on halogen incineration. During the compatibility process, it is easy to cause a certain period of time. Sulfur and halogen hazardous waste enter the furnace, leading to a series of problems such as serious acid corrosion and excessive pollutants in the hazardous waste incineration system; and excessive copper content, resulting in excessive dioxins produced during high-sulfur and high-halogen incineration
