Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used as pressure vessels for processes such as sulfidation, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation. A manhole is opened on the top of a large reactor. The opening of the manhole facilitates workers to enter the reactor for maintenance or overhaul. Waste gas is often released during the process of production in the reactor. The waste gas generated in the reactor is released into the waste gas collection and treatment device through the reactor manhole. Usually, a waste gas collection hood is installed above the reactor mouth. The waste gas collection hood is installed above the manhole of the reactor as an external accessory, and the waste gas is guided to the waste gas treatment device for treatment through connecting pipes or other means.
