| titleOfInvention | Process for removing NOx in waste gas generated by burning tetrachloroethylene residual liquid |
| abstract | The invention relates to the technical field of tetrachloroethylene raffinate treatment, in particular to a process for removing NOx in waste gas generated by burning tetrachloroethylene raffinate, which comprises the following steps: when the tetrachloroethylene residual liquid is burnt, the adding amount of the hydrogen-containing fuel is controlled, so that chlorine can be generated in the tetrachloroethylene residual liquid in the burning process; and sequentially cooling, falling film absorption and water washing the generated waste gas, then carrying out alkali washing treatment, adding a strong oxidant into alkali washing liquid subjected to the alkali washing treatment, and finally discharging the waste gas to finish the process of removing NOx in the waste gas generated by burning the tetrachloroethylene residual liquid. The invention keeps the burning process in a hydrogen deficiency state by controlling the introduction amount of hydrogen-containing fuel in the burning process of the tetrachloroethylene residual liquid, so that chlorine with strong oxidizing property is generated by chlorine element in the residual liquid in the hydrogen deficiency environment, namely, strong oxidizer is prepared during the burning process, and the strong oxidizer can oxidize NO in the waste gas into NO 2 Thereby achieving the purpose of reducing the NO content in the waste gas at the outlet of the incinerator. |
