AI Technical Summary

Technical Problem

When desulfurization of existing carbon black tail gas desulfurization devices, the tail gas temperature is high and contains solid impurities, which affects the desulfurization efficiency and leads to lower practicality.

Method used

A carbon black tail gas high-temperature desulfurization device is designed, including a desulfurization tower and spraying parts. The spraying components include air intake pipe, degrid box, water storage tank, water pump, spray head, filter plate, cooling component and cleaning component. The exhaust gas is sprayed and filtered through the spraying component, and impurities in the exhaust gas are removed in advance. After cooling, it enters the desulfurization tower for high-temperature desulfurization.

Benefits of technology

Effectively remove impurities in the exhaust gas in advance, improve desulfurization efficiency, enhance the practicality of the device, and ensure the stability of the exhaust gas desulfurization.
