Chlorinated slag high-temperature water quenching chlorine-containing waste gas analysis method and treatment system

Abstract

The invention discloses a chloridized slag high-temperature water quenching chlorine-containing waste gas analysis method and a treatment system, belongs to the technical field of waste gas analysis,and provides a chloridized slag high-temperature water quenching chlorine-containing waste gas analysis method, namely the treatment system. According to the invention, water quenching treatment is simulated in the water quenching device, corresponding waste gas generated by water quenching is collected to sequentially carry out pretreatment, acid absorption treatment, alkali absorption treatmentand drying treatment, and metering is performed; then the absorption liquid subjected to acid absorption treatment and alkali absorption treatment is respectively detected to measure the content of chlorine and hydrogen chloride in the waste gas, and calculate the concentrations of corresponding chlorine and hydrogen chloride in the waste gas generated by water quenching in combination with test parameters such as waste gas metering data so as to realize analysis and treatment of the chlorinated slag high-temperature water quenching chlorine-containing waste gas.

Description

technical field [0001] The invention relates to the technical field of waste gas analysis, in particular to a method for analyzing chlorine-containing waste gas by high-temperature water quenching of chlorinated slag and a treatment system. Background technique [0002] In the production process of titanium extraction by the chlorination method, tailings are generated after high-temperature carbonization and low-temperature chlorination processes, that is, chloride slag; and a small amount of high-concentration chlorine gas remains in the tailings. Under the current environmental protection situation, it is necessary to The chlorination tailings are subjected to water quenching treatment so that the treated chlorination tailings can be reused. At this stage, the chlorinated slag has not yet undergone engineering treatment. During the process of taking slag samples from the high-temperature tailings silo at the production site, some chlorine gas leaked out, which made the sam...

AI Technical Summary

Problems solved by technology

At this stage, the chlorinated slag has not yet undergone engineering treatment. During the process of taking slag samples from the high-temperature tailings silo at the production site, some chlorine gas leaked out, which made the sampling conditions of the high-temperature chlorinated slag more complicated. The high-temperature slag samples taken out are as follows: How to quantitatively collect, detect and analyze the waste gas generated after water quenching? For these problems, there are no relevant treatment methods and standards for reference.
